The Southeastern Public Service Authority (SPSA) is proposing to charge $1 per house per month beginning July 1, 1996, for curbside recycling service. The FY 1996-97 estimated cost to provide this service to Virginia Beach residents currently receiving SPS,4 curbside service is approximately $1.2- MILLION. This fee could ultimately grow to $1.3-MILLION as SPSA curbside collection expands to all 112,000 residences currently served by the City's Waste Management Division. The City can reasonably expect that efforts will be made to increase this fee in later years. SPSA is also proposing a reduction in its tipping fee from $48.20/ton to $45.00/ton, upon implementation of the proposed curbside recycling fee. The City Manager could not recommend Virginia Beach agree to this fee. The City Manager distributed a policy report prepared by the Department of Public Works, citing several alternative courses of action available to the City that are more cost-effective and advantageous should the City elect to discontinue this service. Said report is hereby made a part of the record. The City's Agreement for Disposal of Ash and Processed Residue with SPSA has a provision that effectively caps the tipping fee Virginia Beach pays to SPSA. The City required this provision to protect the City against an uncertain cost structure. 7his proposed fee is in addition to the tipping fees and has not been included in the FY 96197 Operating Budget. The City Manager advised unless otherwise directed, the City's representatives will vote against the increased fee during the Southeastern Public Service Authority Meeting on April 24, 1996.

Stone, Chair Virginia Beach CPMT Department of Social Services 2432 Virginia Beach Boulevard Virginia Beach, VA 23452-4497 Dear Dan: On behalf of the State Family Preservation and Family Support Services Planning Committee, I am pleased to inform you that your five year plan for Virginia Beach has been approved. Implementation of the plan may begin immediately. Accompanying this letter are instructions on the fiscal procedures necessary to track expenditures and receive reimbursement for costs incurred in the implementation of your plan. We thought your revisions made the plan much stronger. The programs were well described. The plan contained a well-developed set of measurable objectives. We appreciated your analysis that linked the needs you prioritized with the programs you proposed. As was discussed with Susan Dye on the phone, we still had some concerns about the domestic violence legal support program. We are recommending that you develop a written agreement with the Commonwealth Attorney's Office that would make explicit some of the assumptions underlying the program, and that these include: 1. That Virginia Beach will fund the position. 2. That the foremost issue in connection with any proposed prosecution will be to protect all family members. 3. That a wide range of sanctioning and/or sentencing guidelines and options will be utilized to preserve and strengthen families as appropriate. An Equal Opportunity Agency Mr. Dan Stone. Page 2 4 That all services will be directed toward serving and Supporting families so that to the fullest extent possible, they may maintain family safety, integrity, and independence. Our purpose in suggesting this agreement is to ensure that the funds are used to support, protect, and preserve individuals and families whenever possible. We do not recommend that prosecution for the sake of punishment be the sole criterion considered when these cases come before the court. Your team may also want to consider developing relationships with the media or creating some public awareness strategy to maximize the benefits of this program. Again we offer our congratulations to the planning group and to all the people who have contributed to your effort, and wish Virginia Beach the best of luck in implementing your Family Preservation/Family Support programs and services. Please feel free to contact Eliot Rosenbloom (804-692-1291) if you have any questions about this letter or would like assistance in developing or continuing your initiative. Sinceit@ly.

Oberndorf and Members of City Council Re: Public Works Specifications and Standards Manual Amendment Number Two Dear Council Members: The agenda package for council's April 23, 1996 meeting includes Amendment Number Two, a compilation of proposed revisions to the Public Works Specifications and Standards Manual. These revisions address items requiring clarification or supplemental information identified during the last year of using the manual. They have been compiled by staff with input from consultants and outside agencies to improve the content and clarity of the manual. A letter from the Tidewater Builders Association is attached recommending adoption of these revisions. Highlights of these revisions are summarized below. The majority of revisions to this manual are the result of the recently adopted changes to the Storm Water Management ordinance which was updated to reflect state requirements. This affected mainly Chapters 8, 10, and 11, the Table of Contents, and Appendixes E and F. Revisions include changes in definitions, wording, and terminology. Some additional minor changes have been incorporated to clarify and/or to bring attention and understanding to existing requirements of storm water management. Another large segment of revisions deals with Traffic Engineering technical issues and updates. Chapters 2 and 16 have been revised to reflect new sign post specifications, including the "quick punch" sign post and updated traffic control regulations, references and materials to meet the latest state and national standards. Section 16.4.13 has been revised to restrict the amount of time The Honorable Meyera E. Oberndorf and Members of City Council April 5, 1996 Page 2 that obstructions next to travel lanes can remain. Construction involving utility cuts, pavement "drop-offs" (differences in work area/travel lane elevations), temporary traffic control devices, pavement reconstruction/repavement, and other similar construction work that hinders the traveling public, must now be completed and disturbed areas restored in a reasonable amount of time, as specified in this section. Chapter One has been revised to reflect updated technical references as well as to expand and clarify the explanation of the intent of the manual in subsection 1.0. Chapter Two revisions, beside those involving the Traffic Engineering issues, also provide clarification of requirements to seal lift holes on all drainage pipes and to seal the pipe-joints and tie-in locations between a pipe and a structure using appropriate fabric material. Chapter Three has been revised to reflect updated terminology in the Storm Water Management Ordinance. Additional changes ensure consistency with the City Zoning ordinance for drive aisle widths in parking lots. Chapter Five reflects additional definitions for types of streets to avoid confusion with pavement designs. Additional minor items for clarification of soil boring tests and minimum roadway patch pavement thickness is shown. Section 5.1.1 designates the AASHTO method and the Vaswani (VDOT) method of pavement design as the City's official methods with other standard methods being used only for comparison. Chapter Eleven refers developers to the upcoming Virginia Beach Development Review Handbook being prepared by the Development Services Center to obtain the latest checklists, process explanations, legal forms, etc. Section 11.11 and 11.17 expands the requirement for dumpsters and for dumpster pads on commercial and multi-family residential site plans. Section 11.11 also reflects the requirement for standard perimeter curb around parking lots. Section 12.11(f) has been slightly revised to give more flexibility for the required fill under structures, particularly single family structures where cost and small lot size are factors to consider. In Appendix A, drawing A-18 reflects a prominent note giving direction to the City review engineer, planner or other City office involved in a decision to reduce the width of a road, as to what is The Honorable Meyera E. Oberndorf and Members of City Council April 5, 1996 Page 3 required to avoid any loss of state maintenance funds on new streets. If less than a thirty-foot (30') wide hard surface is built, then approval from VDOT is required. Drawings A-20 through A-28 have been requested by the Planning Department for the new B- 3A Zoning District in the Central Business District (CBD). Drawings B-3, B-6, B-7, B-8, B-9 and B-13 in Appendix B reflect some minor option changes and typographical corrections. Drawings B-37 and B-38 are new City Standard Shallow Drainage Structures where usual VDOT or City inlets cannot be used. Drawing C-2, Appendix C has been revised to reflect finishing work required on the standard City Permanent Survey Monument. Drawings C-3 and C-4 reflect changes to highlight the intent and appropriate use for small pavement patching rather than more extensive pavement reconstruction. Appendix E shows a slightly revised Table 4-1 to be more consistent with the rainfall volumes and intensities in the National Weather Service data (TP-40). Additional sheets have been revised to reflect the new organizational changes with the Planning Department's Development Services Center, Permits and Inspections, and Civil Inspections role in all development related plans. I will be glad to provide you with any information you may need. With pride in our City, t Jam X- Spore cit anager JI<S/RHE/jh Attachments Note: This document is 196 pages.

It is also a reference to policies, procedures, and ordinances related to public and private improvements for infrastructure. This manual is a supplement to other City ordinances referenced within the chapters such as the City Zoning, Site Plan, Subdivision and other ordinances and does not in any way waive specific requirements of such ordinances. This manual applies to all users, public and private. City contracts may possibly call for some modification of a literal application for some of these requirements based on applicability of City policies and procedures. Design, Review, Operation and Inspection agencies should recognize practicality in this regard. This manual provides flexibility for items such as design parameters, accepted engineering practice, and operation requirements as long as the goals of longevity, long term economy, functioning, reasonable maintenance, and other good engineering practices of the system are met. Items requiring waivers or variances are noted in the manual and are generally related to performance, materials, policies, ordinances, etc. The user of this manual must employ sound, professional engineering judgement to assure that each design, and the subsequent construction, applies these Specifications and Standards to result in functional infrastructure in the best interests of the health, safety, and welfare of the public. These specifications and standards are also intended to be flexible and adaptable as new materials, equipment, and methods become available. This publication consolidates, collects, and/or references necessary design, construction, operations, and development related information into one reference manual, wherever possible. Thereby, this will assist in the reduction of potential conflicts and deficiencies. suggestions and comments are solicited from users of this publication for improvement to this manual. Whenever the public interest will be best served, the material will be incorporated by future revisions to this manual. The Department of Public Works will continue to review and research new materials and publications. We welcome your contribution.

SECTION 2.1 Storm Sewers For the purpose of analysis, design and designation, a storm sewer is defined as follows: "Generally, a drainage system, installed to convey storm water, consisting of one or more pipes connecting one or more drop inlets, catch basins, and/or manholes is considered to be a storm sewer. An exception to this general rule is; one or more cross drain pipes connecting two or more drop inlets hydraulically designed as a culvert(s) and not connected to a storm sewer." When storm sewer pipes convey public waters, any connections shall be with a standard drainage structure as referenced in this manual. Helically corrugated pipe shall have a minimum of two (2) annular corrugations on each end. Connecting bands shall engage at least one annular corrugation on each side of the joint for the full periphery of the pipe. Fiber Bond corrugated steel pipe shall conform to ASTM Designation A885.

C) Due to the nature of construction work, it will not always be possible to operate within this framework. In the interest of economy, practicality and in emergency situations, deviations may be approved by the City Manager. SECTION 3.7.13 North Beach Improvement With each site plan or subdivision development in the North Beach area the developer is required to record an agreement which states that he will pay 100% of the cost for standard right of way improvements along the frontage of his site, should the city have a project to improve the street frontage under the Installing Drainage Pipe, Curb and Gutter and sidewalks Upon Recruest of Private Property Owners Policy. This would apply to all minor streets and alleys between 49th Street and 89th Street, including the Princess Anne Hills area. This agreement is to include the owners consent to dedicate any right of way if needed for the project. Right of way improvements along Atlantic Avenue should be treated as usual with the plan being reviewed, by the City Engineer. This agreement becomes necessary since we have begun contacting property owners along specific streets in North Beach to see if they desire to participate in curb and gutter improvements. The North Beach Street Improvement Policy (Section 6.2.5) includes: curb and gutter, drainage improvements, street light upgrades, and pavement widening. These projects are generally following the areas being improved with the North Beach Storm Drainage Projects scheduled in the C.I.P. Revised 1/9 Geometric Alignment & Design age 3 - 25 Public Works Specifications and Standards SECTION 3.7.14 Right of Way Improvement - Development Plans The purpose of this regulation is to provide guidelines in the establishment of of f -site right of way improvements associated with proposed development.

Page 3 - 30 Geometric Alignment & Design Revised 1/96 Public Works Specifications and Standards SECTION-3.9 Roadway Alignment Contact the City Engineer's office and Traffic Engineering for specific information concerning any roadway alignment to see if there is a preliminary alignment or plans available. SECTION 3.10 Turn Lanes SECTION 3.10.1 General The following criteria is applicable in determining the requirement for the construction of right and left turn lanes. These turn lane standards have been established to expedite the movement of through traffic, to control the movement of turning traffic, to increase the capacity of intersections, and to improve the safety characteristics of roadways. SECTION 3.10.2 Right Turn Lanes Justification A right turn lane may be required when the location being studied generates thirty-f ive (35) or more vehicles entering in the peak hour. However, other factors such as accident history and analysis, pedestrian conf licts, and the existing highway capacity must also be considered for the justif ication of the installation of a right turn lane and will be determined by the City Engineer. SECTION 3.10.3 Right Turn Lane Goometrics Typically, a right turn lane shall measure 150 feet in length with a 150 foot bay taper transition. a) Width - A twelve (12) f oot turn lane width is required f or right turn lanes with any new road projects or development. The width of the turning lane shall not include the gutter pan. b) Bay Taper - A straight taper along the right edge of the travelled way is used to guide vehicles into the turning lane. This taper is generally 1501 feet long. A short radius should be used at the beginning and end of the bay taper. c) Deceleration Length - The posted, or if available; the 85th percentile speed should be used in determining the deceleration length. 3001 feet of deceleration lane is required where full deceleration is desired of f high speed through lanes. The deceleration length includes the bay taper length. Revised 1/ Geometric Aligrment & Design Page 3 - 31 Public Works Specifications and standards d) Storage Length - Storage length of a right turn lane at unsignalized intersections is determined by the proposed or posted speed limit as follows: MINIMUM STORAGE LENGTH / BAY TAPER LENGTH BASED ON MPH 25 MPH to 30 MPH = 100'/100' 35 MPH > = 1501 / 1501 At signalized intersections, storage length should be based on two (2) times the average number of vehicles that would store per signal cycle (peak hour)depending on length, phasing and arrival / departure rates. The storage lane length shall not be less than the minimum. SECTION 3.10.4 Entrances Located Within The Right Turn Lane Entrances are allowed in the turn lane only when no alternative access is available. At least 501 on tangent is required between the curb but and the end of the bay taper. This distance should be as long as possible. SECTION 3.10.5 Substandard Right Turn Lanes on Corner Sites See the City Subdivision ordinance sec. 4.4.2 and this distance is also used as a standard for site plans on corner lots. SECTION 3.10.6 Right of Way Dedication for Right Turn Lanes Right of way dedication for turn lanes will be required when turn lanes are required. SECTION 3.10.7 Left Turn Lane Justification A left turn lane may be required when the site being studied generates thirty (30) or more trips per day. Accident history and existing capacity may also be factors in determining the need for a left turn lane. At signalized intersections left turn lanes shall be based on supporting evidence. Page Geometric Alignment @Design Re ised 1/96 Public works Specifications and Standards SECTION 3.10-6 Left Turn Lane Goometrics Left turn storage lanes should be at least 1501 in length with a 1501 bay taper transition. The dimensions will be reviewed on a case by case basis, by the Traf f ic Engineer, where site frontage is limited, or where existing right of way is not sufficient. Also, see Section 3.10.3 for left turn lane dimensions. SECTION 3.10-2 Left Turn Lane Approach Transition Whenever a left turn lane is required where there is not a median, an approach taper to the left turning lane must be installed. The approach taper length will be determined by the following formulas. a. For speeds 45 or more : L = S x W WS2 b. For speeds 40 or less : L = --- 60 Where: L = Length in feet S = 85th (or posted) percentile speed W = Offset in feet SECTION 3.11 MXedian Crossover spacina GBCTION 3.11.1 General The application of median crossover spacings on all divided roadways without full control of access in the City of Virginia Beach shall follow the design criteria as established in the current edition of the Roadside Desicrn Guide published by the Virginia Department of Transportation. Revised 1/96- eometric Alignment & Design Page 3 - 33 Public Works Specifications and Standards SECTION 3.11.2 Spacing Criteria Table The following table lists the desirable and minimum median crossover spacings for divided roadways based on design speed and minimum sight distance. This table is based on the VDOT Roadside Design Manual. TABLE III - 4 CROSSOVER SPACING CRITERIA Design Speed crossing spacing Minimum of Sight Highway Desirable xin![-Ua Distance (MPH) (Post) (Feet) (Feet) 70 1250 1000 825 60 1100 900 700 55 1000 800 650 50 900 700 600 45 800 650 525 40 700 600 475 35 600 500 400 The minimum sight distance requirement must be met at all crossover locations. SECTION 3.11.3 Reduction of Minimum Spacing Standards Consideration in crossover spacing less than the established minimum will be given for intersecting Rublic roadways with a current ADT of loo or greater. Crossovers for private streets or commercial entrances will be considered on a case by case basis following an evaluation of an individual traffic safety and operation study. This study shall be submitted by the design consultant and evaluated by Public Works Engineering. Factors to be included in the study (but not limited to) shall be: operating speed, volume of traffic for crossover and the through street, signal operation/progression, accidents with and without the crossover, number of U-turns, weaving maneuvers, alternative solution, capacity analysis, type of vehicles, etc. Final approval (waiver) for reduction in median spacing shall be by the City Engineer. Page 3 34 Geometric Alignment & Design R vised 1/96 Public Works Specifications and Standards BECTI)N-3.12 Sight Distance BECTI)N 3.12.1 General The following standards are established concerning safe vertical and horizontal sight distance at street and driveway intersections. This criteria has been established to ensure that sufficient sight distance is available to the driver to permit a safe maneuver across or onto an intersecting roadway. SECTION 3.12.2 Visibility Triangle The visibility triangle is the area along the intersection needed to ensure safe maneuvering across or onto an intersecting roadway. The visibility triangle is formed by using the speed limit (preferably the 85th percentile if available) in Table III - 5 below determine the sight distance from the edge of travelled roadway. Placing the driver on the controlled minor approach twelve (12) feet back from the intersecting major roadway, a "line of sight" from the driver to the determined distance on the intersecting road will form the visibility triangle (see Appendix D-7). In this visibility triangle, nothing shall be erected, placed, parked, planted or allowed to grow in such a manner as to impede vision of the driver a height of two and one-half (2.5) feet above the centerline of the intersecting roadways. SECTION 3.12.3 Sight Distance at Intersections Non-signalized intersections where a minor road meets a major road, or two (2) major roads intersect, commercial entrances and crossovers are required to have sufficient sight distance to permit a safe departure from a stopped position. Sight distance requirements may be reduced at signalized intersections for protected movements since ideally the traffic signal assigns the right-of-way thereby reducing the visibility required. However, unprotected right and left turning movements still need to meet the sight distance criteria. Table III - 5 provides the required sight distance based on the speed limit of the non-controlled (approaching) leg of the intersection. The 85th percentile speed should be used if available for improved accuracy. @/VD ueometr Public Works Specifications and Standards TABLE III - 5 Sight Distance at Intersections MPH 25 35 45 55 Residential / local streets: 250' 350' 450' 550' Residential collectors, minor arterial rural roads: 350' 500' 600' 750' major arterial, interchanges, etc.: 500' 600' 775' 950, SECTION 3.13.4 Stopping Sight Distance Stopping sight distance is the minimum sight distance allowable at a corner intersection and will only be used when proper sight distance (Table III -7 5) cannot physically be obtained, because of existing conditions or monetary constraints prohibit using the corner sight distance. TABLE III - 6 Stopping Sight Distance MPH 25 35 45 55 Stopping Sight Distance: 150' 250' 345' 470' SECTION 3.13 Bus Turnouts Bus turnouts shall be provided at bus stops on major arterials. The turnouts shall be twelve (12) feet wide, not including the curb and gutter, and a minimum tangent length of eighty (80) feet, with fifty foot pavement transitions. The transitions shall have reversed radii, a minimum 300 feet, on the both the entrance and exit end of the turnout. A "BUSES ONLY" sign shall be placed adjacent to the turnout in the vicinity of the bus loading point. Page 3 - 36 Geometric M igrment & Design Re ised 1/96 Public Works Specifications and Standards SECTION-3.14 Guardrail SECTION 3.14.1 General The application of guardrail installations in the City of Virginia Beach shall follow the design criteria as established in the Roadside Design Guide published by the American Association of State Highway and Transportation officials, copyright 1989 (or current edition). SECTION 3.14.2 Guardrail Type As a basic guide for guardrail selection, the City of Virginia Beach utilizes standard GR-2 (strong post) guardrail with standard GR-7 (wood post) breakaway cable end treatment. Any change from these standard types must be justif ied by the designer/developer and will be considered on an individual basis by the City Engineer. SECTION 3.14.3 Guardrail Placement A guardrail installation shall be considered at all locations where clear zone requirements are not met for fixed objects, embankments, bodies of water, or where a large number of bystanders or pedestrians may be expected. on curbed sections of roadway, the f ace of the W beam guardrail shall be vertically aligned six (6) inches behind the face of the curb. Revised 1/96 Geometric Alignment & Design Page 3 - 37 Public Works Specifications and Standards CHAPTER 5 PAVEMENT DEsiGN SECTION 5.0 General All pavement designs shall be certified by a licensed professional engineer and shall conform to the criteria listed within this chapter as applicable. SECTION 5.1 Method of Determining Traffic Volumes For the purpose of determining traffic volumes, average trips per dwelling units of vehicles per day shall be used. Traffic generation shall be determined by multiplying the average twelve (12) trips by the number of dwelling units to be served by the street to be designed. A collector or arterial street shall be designed by using the sum of traffic generated by local or intersecting streets. A minimum ten percent (10%) truck traffic for industrial and commercial streets, seven percent (7%) for major collector and arterial streets of 4 lanes or wider, and five percent (5%) trucks for all other streets shall be used in the design of new and reconstructed pavement. . For design purposes one (1) truck shall equal 11,300 cars, where not otherwise specified by a particular design method. SECTION 5.1.1 Pavement Design methods and Life The AASHTO method of determining pavement design is acceptable for design of pavements. Otherwise, the Vaswani Method (VDOT) shall be used for design of roadway pavements. Other methods such as the Asphalt Institute MS-1 method may be used for comparison and information only. Pavement life within the geographical boundaries of the City of Virginia Beach shall be designed as follows: Major roads 35 years Minor roads 35 years The following growth rate for pavement design shall be used unless a different growth factor is substantiated: Industrial, commercial, Major Collector and Arterial Streets ........................... 6% Minor Collector Streets (2 lanes) .......... 5% Subdivision or Residential Through Streets.4% Subdivision or Residential Loop Streets .... 3% Subdivision or Residential Cul-de-sacs ..... 2% Revised 1/96 Pavement Design Page 5 - I Public Works Specifications and Standards subdivision through streets are generally streets that connect through from one side of a subdivision or neighborhood to the other side; or such street that is mainly used by motorists passing through and not stopping in a neighborhood. Loop streets are such streets that loop back to the same road and connect at two separate locations to the same road within a particular subdivision development or neighborhood. SECTION 5.2 Design Wheel Loads Pavement design shall be based on the following wheel loads: (a) Minor streets .................... 12,000 lbs (b) Collector streets ................ 12,000 lbs (c) Major collector & industrial ..... 12,000 lbs (d) Arterial streets (801 R/W) ....... 15,000 lbs (e) Arterial streets (901 - 1101 R/W) 18,000 lbs SECTION 5.3 Soil and Subgrade Requirements All soil and subgrade information shall be evaluated by the engineer prior to design of pavements. Soil and subgrade information as specified in Chapter 4 entitled "Geotechnical Information & Design", shall be submitted to the City to substantiate the pavement design prior to plan approval in accordance with these criteria. Local materials that under normal conditions may be unsatisfactory for use in construction may be acceptable when stabilized with lime, cement, or geogrids in accordance with these standards and criteria. For other than condominium, apartments and private parking (on site) a minimum CBR value of 9 on the subgrade support soils has been assumed. Where subgrade support soils indicate a CBR value of less than 9, the design should include a method for stabilization and proper support either through the use of geogrids or removal by undercutting or by lime or soil cement stabilization. Where field conditions indicate further selective areas of poor or yielding subgrade upon exposure of the subgrade, these substandard areas shall be undercut to provide for additional subbase, base, or select material (in compliance with Section 2.5 and/or 2.6 of this manual) as directed by the Department of Public Works. As an alternative to undercutting, the Department of Public Works may require raising the CBR value to a minimum of 10 by stabilization of the subgrade soil with lime or cement. The stabilization of subgrade shall be to a depth as established by VDOT publication Virginia's Method of Conducting CBR Test and Designing Flexible and Rigig Pavements (1952), or other acceptable method. Page 5 2 Pavement Design Revised 1/96 Public Works Specifications and standards When the CBR values of a soil are low (between 2 to 8), rather than using the maximum soil support factor of 3 automatically; the soil shall be classif ied using the Vaswani Method to determine the correct soil support factor. Also, two-thirds (2/3) of the average CBR value shall be used for the Vaswani Pavement Design Method (or any other method of Pavement design used for comparison) instead of the average CBR value. VDOT indicated that their nomographs were intended to be used with a two- thirds the average CBR since the procedure for soaking a soil sample may not be long enough to give a representative soaked CBR value of the soil in its native condition. A minimum of one CBR test for each cul-de-sac is required unless a CBR test has already been taken within 500 feet of the entire length of the cul-de-sac. All open graded beach type sand shall be removed and root material h'I diameter and larger and/or root mat (organic material) as directed by the Public Works inspector or Planning civil inspector. a) Definition Group Index (GI) GI = (F-35)[0.2+0.005(LL-40)]+O.Ol(F-15)(PI-10) where: F percentage passing 0.075 mm (No. 200) sieve, expressed as a whole number. (Do not include material larger than 3 inches) LL Liquid Limit PI Plasticity Index b) General information and guidelines for subgrade soils The following soils generally provide a good subgrade: Soils in groups GW, GP, GM, GC, SW, SP, SC (with CBR > 10), and SM (Unified Soil Classifications) Revised 1/96 Pavement Design Page 5 - 3 Public Works Specifications and Standards Soils in groups A-1, A-2, A-3, A-4 (with CBR > 10), (AASHTO & SCS Soil Classification) The following soils generally provide a poor subgrade and should be designated in the pavement design to be removed, stabilized, or bridged with stone columns, tensile geogrid and geotextile fabric. Soils in groups OL,,MH, CL, ML, SC (with CBR < 10), OH, and Pt (Unified Soil Classification). Soils in groups A-4 (with CBR < 10), A-5, A-6, and A-7 (AASHTO & SCS Soil Classification) High elasticity and poor subgrade support leads to fatigue cracking of pavements. If test on the items listed below are beyond the limits specified then subgrade removal of minimum of 1211 will generally be required or subgrade stabilization must be designed, unless the City review engineer deems this unnecessary due to other means of handling a particular unsuitable soil situation: Recommended Values Group index values <13 CBR (soaked @ 95% max., @ 8 compaction, 24 hrs. min. Permeability >10-4 Standard boring spoon >4 blows/foot for clay penetration Shear strength 2: 169 lb/ft2(27N/CM2) (0.40 kglcm2 Subgrade modulus >100 lb/inj Unconfined compressive Strength (for cohesive >317 lb/ft2 (0.75 kg/CM2 (soils) Particle size analysis <35% silt and/or clay with remainder being sand > 65% Liquid limit <50 Plasticity index <30 organics <5% (depending on depth) Moisture density test using Standard Proctor The professional soils engineer who performs these tests shall recommend a method of subgrade stabilization to the city as applicable. All pavement designs will include subgrade testing (in accordance with AASHTO, ASTM and/or VTM Page 5 4 Pavement Design Revised 1/96 Public works specifications and Standards standards and every 500 feet/2 lanes). CBR tests must be performed in accordance with Section 4.3 and to be run only for 95% compaction. If the subgrade can not be compacted to 95% due to high moisture content, etc. then the subgrade must be stabilized or undercut. Compaction and proof-roll of subgrade and aggregate layer is required with a fifty (50) ton roller on roadways with vpd > 5,000 or a fully loaded tandem dump truck on streets with < 5, 000 vpd and on private parking lots, etc., even if not listed in each individual design and/or plan. If soils (minimum 21 below the top of the compacted subgrade) contain more than 35% clay and silt combined or where high water table exist then underdrains or road edge drains shall be installed as required in Section 2.2.7. soils with large percentages of clay shall be protected from traffic, disturbance, and water. Otherwise, they will soften and will be required to be removed. SECTION 5.3.1 Chemical Subgrade Stabilization General guidelines: Each situation should be evaluated by the design engineer on a case by case basis. In all cases, driving on stabilized subgrade should not be allowed. The Virginia Test Method for Lime Stabilization (VTM-11, July 1, 1979) shall be used to determine the percent of lime to stabilize the soils. Asphalt stabilization shall not to be used on soils with greater than 25% passing the number 200 sieve. The Plastic Index value must be less than 6 and must have a sand equivalent less than 25. AASHTO soils Al-2, Al-6, A2-4, A2-6, A-3, A-4 and some A-6 with low plasticity are recommended for this type of stabilization. Soil cement and lime stabilization shall not be used on soils with greater than 20% silt or 40% clay or where organic material is present and when the plasticity index is less than 12. For silts, use a 10% to 20% fly ash 80% to 90% lime mixture. Use of A-4 or A-7 soils is recommended for lime stabilization. Tests for unconfined compressive strength or CBR tests for soil stabilized with lime and cement shall be performed by the design engineer prior to specification. Unconfined compressive Revised 1/96 Pavement Design Page 5 5 Public Works specifications and Standards strength shall be equal to or greater than 500 p.s.i. and/or CBR values shall be equal to or greater than 15 for material after stabilization with lime or cement. Soil cement guidelines: AASHTO CEMENT % CEMENT % SOIL BY VOLUME BY WEIGHT AlA 5 - 7 3 - 5 AIB 7 - 9 5 - 8 A-2 7 - 10 5 - 9 A-3 8 - 12 7 - 11 A-4 8 - 12 7 - 12 A-5 8 - 12 8 - 13 A-6 10 - 14 9 - 15 A-7 10 - 14 10 - 16 Heavy clay: lime reacts better the heavier the clay; add: 5% to 10% by weight lime for base 1% to 3% by wight lime for subbase Clay gravel mixtures: add 2% - 4% lime by weight pH of material after lime stabilization should be in the range of 12.5 General percentage of lime = liquid limit x 0.12 if LL < 50 General percentage of lime = liquid limit x 0.12 if LL > 50 Hydrated lime cannot be used without a dust control plan and cannot be used adjacent to residential areas or in windy weather conditions. Notes shall be added to the plans concerning these issues. water trucks should be on site for soil cement and lime stabilization prior to placement even if soil is wet and saturated. Soil cement and lime may take more water than is naturally available even in wet conditions. Lime soil mixtures should be mixed and cured for 48 hours before final mixing and then compacting. Care should be taken during winter months, the freeze/thaw cycle may negate the soil cement application before hydration has occurred. Curing times for soil cement and lime stabilization shall be in accordance with VDOT, Road and Bridge Specifications, Section 306, or as determined by the Public Works Inspector, however, lime may take 30 days Page 5 6 Pavement Design Revised 1/96 Public Works Specifications and-Standards Soil cement and lime can be utilized to stabilize subgrades as determined on a case by case basis by the design engineer. Soil cement and lime stabilized subgrades should have a minimum equivalent CBR value of 8, however, a value greater than 12 will not be allowed for design analysis. Stabilized subgrades shall be designed to provide equivalent pavement system performance as a pavement system designed utilizing a subgrade meeting the minimum recommended values presented in Section 5.3 (b). Fly ash should not be mixed with fine grained soils. SECTION 5.3.2 Geotextile, Geogrids and Underdrains Geotextiles should be used when undercutting is utilized to remove unsuitable subgrade soil. The geotextile should be placed at the bottom of the undercut zone to separate the select backf ill from the native soil. Geotextiles will not be required if it is demonstrated that the following criteria is met. Dis BF D50 BF 5, & < 25 D85 SG D50 SG The geotextile shall meet the criteria f or medium survivability separation geotextiles per AASHTO M288. Geogrids can be utilized to stabilize subgrades as determined on a case by case basis by the design engineer. Geogrid stabilized subgrades should have a minimum equivalent CBR value of 8, however, a value greater than 10 will not be allowed for design analysis. Geogrid design calculations must be supported through the use of a layer coefficient ratio which can be verified from independent, full-scale testing similar to that described in DOT/FAA RD-92/25 and have a documented performance history of not less than 3 years. Geogrid stabilized subgrades shall be designed to provide equivalent pavement system performance as a pavement system designed utilizing a subgrade meeting the minimum recommended values presented in Section 5.3 (b).

One and one-half (1k) inches of cement stabilized subgrade for one (1) inch of untreated compacted VDOT Type I or Type II aggregate; a substitution ratio of 1.5:1. 4. One (1) inch of crushed hydraulic cement concrete for one (1) inch of untreated compacted VDOT Type I or Type II aggregate; a substitution ratio of 1:1. 5. Two (2) inches of lime stabilized soil for one (1) inch of asphalt; a substitution ratio of 2:1. 6. The following minimum thickness will be required for soil chemical stabilization: a) Six (6) inches of soil cement b) Eight (8) inches of lime stabilization Where designs provide for reduction of the thickness of the base course by stabilization of the subgrade, the maximum reduction shall be three (3) inches. Where stabilized material is to be substituted for base material, the minimum compressive strength at seven (7) days shall be 500 psi. 7. The minimum depth of any aggregate base shall be four (4) inches with an intermediate base course (such as BM or IM) or six (6) inches without an intermediate base course. C) When the various VDOT approved "Vaswani Methods" of pavement design are used and more than one layer of asphalt is required, the surface course (SM-2A or SM-2C) and the intermediate course (IM-LA or IM- IB) can be treated as one surf ace layer with the underlying aggregate being treated as the second layer. Revised 1/96 Pavement Design Page 5 - 9 Public works specifications and Standards d) Porous pavement is not allowed in the City right- of-way or in any City easements because of maintenance costs and design parameters. Porous pavement is strongly not recommended for use as a Best Management Practice (BMP), as its effectiveness is minimal due to special equipment required for maintenance. SECTION 5.5 Full-depth Asphalt Pavement Full-depth asphalt pavement shall not be used on untreated subgrade. When full-depth asphalt pavement design is allowed the criteria shall conform to the provisions of the Asphalt Institute Manual Series No. 1 (MS-1). When the above criteria is used for full-depth asphalt pavement design the equivalency factors as established by Asphalt Institute Manual (MS-1) shall apply when utilizing treated or untreated base or subbase. a) When an intermediate binder course of less than three (3) inches is to be used, a minimum two (2) inch lift of either IM-LA or IM-LB may be used. b) The Vaswani method of pavement design specifies that a 311 layer of aggregate be installed between soil cement and an asphalt overlay to prevent reflective cracking. Some severe pavement failures have been documented using 211 S-5 over 311 aggregate over soil cement due to the aggregate moving and shifting on top of the soil cement, even though the soil cement remained in good condition. Therefore, when soil cement is specified, the aggregate layer shall be eliminated and an intermediate asphalt course (BM-3 or IM-2) shall be placed directly on the soil cement under the surface mix to prevent reflective cracking. SECTION 5.6 Minimum Design Standards A minimum design based upon a 12,000 lb. wheel load and a subgrade CBR value of 10 has been established. Where the existing subgrade has a CBR value of 10 or greater; alternative pavement designs may be submitted for review and approval providing the traffic capacity and pavement strength are equal to or greater than the minimum design. Based upon evaluation and analysis of existing flexible pavement failures in Virginia Beach, it is strongly recommended that a minimum three (3) layer pavement design be utilized for roadway construction and reconstruction. (SM bituminous concrete over I or BM Page 5 - 10 Pavement Design Revised 1/96 Public Works Specifications and Standards bituminous concrete over aggregate or other subbase over compacted or stabilized subgrade.) MINIMUM PAVEMENT DESIGNS Concrete: 5" Plain portland cement concrete (on-site) and 8" plain portland cement concrete (in the right of way, over Compacted subgrade Full Depth Asphalt: Total asphalt pavement placed directly on subgrade is not allowed due to poor work product results. Flexible Pavement with Aggregate Base: 2" Bituminous concrete surface, over 6" VDOT Type I or Type II aggregate base, over Compacted subgrade The minimum allowable SM-2A thickness within the City right-of-way shall be two (2) inches over aggregate; 1 1/2" SM-2A may be used if over BM-2 base material. S-5 bituminous concrete may be substituted for SM-2A on-site outside of the public right of way or as approved by the Department of Public Works. Installed pavement thickness must be not less than 90% of each layer specified in a design. otherwise, installed pavement shall be either removed or added, to bring the total thickness up to 100% of that specified in the design. SECTION 5.7 Materials for Design All materials, including their handling, treatment, and placement shall conform to Chapter 2 "Materials" of this publication and the Virginia Department of Transportation Road and Bridge Specifications (1991). Revised 1/96 Pavement Design Page 5 - 11 Public works Specifications and Standards SECTION 5.8 Miscellaneous Design Provisions a) All bridge designs shall be in accordance with the bridge design specif ications established by the American Association of State Highway and Transportation Officials, (AASHTO). b) Where a dam structure is designed as part of a roadway, a special agreement shall be executed with the city to design the spillway on one hundred (100) year frequency recurrence storm. The dam structure shall not be the only access to the properties. C) Parking lot surfaces shall be of Portland cement concrete or asphalt concrete type. d) The perimeter of all driveway and parking areas shall have a minimum six (6) inch concrete curb (VDOT CG-2) along all sides except where the pavement abuts a building. Where parking is shown adjacent and perpendicular to the property lines, the face of curb shall be placed a minimum of two and one-half feet (2 1/2) inside the property line. e) A pocket penetrometer or vane shear (not both) shall be used every 250' plus an observation jar settlement technique every 250' to observe the rough soil gradation in addition to the required CBRs (every 500') at the elevation of the subgrade along the roadway. f) A hydrometer test or equal shall be performed if the material tested is greater than 20% of the sample is passing the number 200 sieve. g) Specify compaction of 95% of Standard Proctor test when designing parking lots and private streets (on site) such as apartments and condominiums; and specify Standard Proctor when designing subdivision and minor streets with less than 5,000 vpd, with compaction at 90% for cohesive and 95% for cohesion less soils. h) Use the Modified Proctor test when designing major streets with 5,000 vpd and greater with compaction at 90% for cohesive and 95% for non-cohesive soils. Page 5 12 Pavement Design Revised 1/96 Public Works Specifications and Standards SECTION 5.9 Asphalt Anti-stripping Recruirements The Department of Public Works requires for all projects approved by the City and for all work in the City right of way the criteria set f orth in this section, in addition to Section 211 of the Virginia Department of Transportation Road and Bridge Specifications, (1991) ; concerning the requirement of the use of hydrated lime in asphalt concrete to meet anti-stripping requirements. The contractor must meet a Tensile Strength Ratio (TSR) of at least 0.75 as set forth in the VDOT specification, however, the use of lime will not be explicitly required. The contractor must document to the city that the TSR is at least 0.75 by the following: a) The proposed job mix formula must include certification that the job mix formula has been tested by an independent testing lab and found to have a TSR of at least 0.75 (the actual TSR must be noted). b) Upon approval by the City of the job mix formula and upon approval by the City of the certification of supply for the component materials of the asphalt concrete, the contractor shall have the test performed as per VDOT specifications, using the materials from the approved sources of supply to establish the actual TSR of the asphalt concrete. The actual value of the TSR must be determined and certified by an independent testing lab and be no less than 0.75. These test shall be done sufficiently in advance of paving operations so as not to impact the contractor's paving schedule. C) Where the contractor quality control requires pavement corings of the contractors in-place asphalt, the TSR or the asphalt concrete must be at least 0.75 and the actual TSR value determined and certified by an independent testing firm. SECTION 5.10 Pavement Conformance Standards Within the City right-of-way and City easements, all surface asphalt must conform to VDOT standards, and must be SM-2A or SM-2C. On private property, S-5 surface course asphalt may be substituted for SM-2A, if specified by the owner. Revised 1/96 Pavement Design Page 5 - 13 Public Works Specifications and Standards SECTION 5.11 Tack Coat and Prime Coat A prime coat may not be required if asphalt is thicker than four (4) inches. A tack coat shall be used for IM-IA, IM-IB, BM-1, BM-2, and BM-3 (or any intermediate course) if the final driving surface is not placed and if traffic has been driving on the surface. SECTION 5.12 Pavement Replacement and Patching Pavement replacement and/or pavement patching in the City of Virginia Beach is required after the roadway surface has been disturbed due to road construction, underground installation or repairs of: sewer, water, storm sewer, telephone, power, cable television, gas, or any other underground utility or service lines. The reviewing and design engineers must use sound engineering judgment in determining whether the roadway work involved constitutes a roadway reconstruction or a roadway patch as defined below. Any pavement replacement or patching shall be bonded as specified in the City of Virginia Beach Right of Way Permit Specifications, and in this section. Definitions - The following definitions are provided to clearly delineate the types of pavement replacement: a) ROADWAY RECONSTRUCTION - shall be defined as reconstruction of pavement that has been removed or damaged to such an extent that a roadway patch (as described below) cannot be used. 1. Roadway reconstruction of any streets, cul-de- sacs, collectors, or major arterials, etc. , shall be considered as the placement of new pavement and therefore, will require the submittal of a pavement design based on at least one CBR test in accordance with City Standards, except that the CBR test shall be on the material placed in the roadway reconstruction. This material may be either select fill (CBR 2 15 with Unified Soil Classification of SC, SW, S, SP, SM, or SW) or the original trench material as mixed, meeting these criteria, and compacted back in the area of excavation. The pavement design will be reviewed by the Department of Public Works review engineer. Select fill shall be used if the material from the excavation is unsuitable. Page 5 14 Pavement Design Revised 1/96 Public Works Specifications and standards b) ROADWAY PATCH - shall be defined as a repair of a pavement that has been cut no more than f ive (5) feet wide, the width of the roadway, and between 45 and 90 degrees to the length of the roadway, or a ten (10) foot by ten (10) foot square, maximum. 1. Roadway patch for residential streets and cul- de-sacs shall be: 1 1/2" SM-2A Bituminous Surface Asphalt concrete, over 2" IM-2A Bituminous Intermediate Base Mix Asphalt Concrete, over 8" Aggregate Base Material, Type I or II No. 21 or 21A, over Compacted subgrade (all existing materials shall be removed and replaced with select fill minimum CBR > 15). Subgrade shall be compacted in 1211 layers to 31 below pavement and then in 6" layers thereafter to 95% of the ASTM D-698 (standard Proctor) maximum theoretical density. Appropriate substitution for soil cement stabilization, lime stabilization and asphalt stabilization shall be used. 2. Roadway patch for collector streets and major arterials shall be the greater of: match the existing pavement section in depth and type of materials, or 1 1/2" SM-2A Bituminous Surface Asphalt Concrete, over 3" BM-2 Bituminous Base Mix Asphalt Concrete, over 8" Aggregate Base Material, Type I or II No. 21 or 21A, over Compacted subgrade (all existing materials shall be removed and replaced with select fill minimum CBR > 15). Subgrade shall be compacted in 12" layers to 31 below pavement and then in 6" layers thereafter to 95% of the ASTM D-698 (standard Proctor) maximum theoretical density. Appropriate substitution for soil cement stabilization, lime stabilization and asphalt stabilization shall be used. Revised 1/96 Pavement Design Page 5 - 15 Public Works Specifications and standards C) When pavement is removed, the replacement will normally be of a similar type, i.e. a concrete pavement section should be replaced with a concrete pavement section and an asphalt pavement section should be replaced with an asphalt section. Exceptions must be specifically approved by the City Engineer. d) Pavement riding surface shall be replaced with similar materials; i.e. replace S-5 with S-5, replace SM-2A with SM-2A, replace concrete with concrete, and replace asphalt over concrete with asphalt over concrete. e) Except as noted below, in cases of items (a)(1) and (b)(1) and (2) above, flowable fill may be used on a case by case basis, as approved by the City Engineer's Office. If flowable fill is proposed for use above sanitary sewers, force mains or water mains, such use must also be approved on a case by case basis by the Department of Public Utilities Engineering Office. Flowable fill shall be used onlv in open cut pavement patches as follows: The entire trench (from 12" above the top of the installed utility) is to be filled to the bottom of the asphalt pavement section (gravel base layer). The first 12" directly above the utility shall be backfilled and compacted with select material CBR > 15 to prevent flowable fill from contacting to the utility line itself. The minimum depth of flowable fill used shall be twelve (12) inches. Mixture design shall be provided to the City by the contractor. The contractor shall submit a mixture design for approval supported by laboratory test data verifying compliance with 28 day compressive strength requirements. Mix design must be approved by the reviewing engineer prior to placement. Flowable fill shall have a compressive strength of 30 to 200 psi at 28 days when tested in accordance with AASHTO T-23. Mixture design shall result in a fluid product having an 811 to 1011 slump at the time of placement. The flowable fill supplied shall be in accordance with Virginia Department of Transportation Road and Bridge Specifications, Sections 109, 202, 203, 216, 217, 219, 241 and 303. Page 5 16 Pavement Design Public works Specifications and Standards NOTE: Flowable fill is normally not acceptable and shall not be used above or within a horizontal distance of two (2) feet of any metal pipes, such as City water or sewer mains and service lines or any metal City facilities such as metal culverts. The contractor must have written approval from the Departments of Public Works and/or Public Utilities, as applicable, if flowable fill is proposed to be used. f) In all cases when a road has been open cut and the final pavement cannot be placed the same workday or the trench backfilled and temporary cold patch placed in accordance with- the City of Virginia Beach Right of Way Permit Specifications; then, the trench shall be backfilled and a temporary steel bridge plate placed over the trench, at the direction of the city inspector. Unless special approval is given by the City, all travel lanes shall be reopened to traf f ic at the end of each workday. only if previously approved by the City may the trench be barricaded by appropriate work area protection as required by City and/or VDOT standards. Again, no travel lanes are to remain closed unless approved by the City. See Section 16.4.13 for restrictions on any work within the public right-of-way that is within ten (10) feet of the travel lane. This includes any work such as (but not limited to) obstructions hindering the motoring public, pavement drop offs, open cuts, utility work, paving, pavement reconstruction, temporary traffic control, construction, or any other issue considered to be a hazard or an inconvenience to the traveling public. g) A one (1) year surety "defect" bond equal to 120% of the project cost shall be required by the City on all private development projects requiring open cutting in accordance with the City of Virginia Beach Right of Way Permit Specifications. The bond amount should include inspection fees, and all associated costs with the replacement of the pavement. The costs of excavating and compacting of backfill should also be included.

Page 5 - Pavement Design Public Works Specifications and Standards CHAPTER 8 STORM WATER MANAGEMENT SECTION 8.0 General a) The storm water management and storm drainage design criteria for open and closed drainage systems shall generally conform to the applicable provisions of the ASCE Design and Construction of Urban Stormwater Management Systems, No. 77, WFF Manual FD-20, 1992 Virginia Department of Transportation- Drainage Manual (1980), the ASCE Manual of Engineering Practice No. 37, WPCF Manual of Practice No. 9, Desicrn and Construction of Sanitary and Storm Sewers 1986, Virginia Erosion and Sediment Control Regulations, (1990), the Virginia Erosion and sediment control Handbook third edition, (1992), and applicable publication; of the Federal Highway Administration. b) Storm water management and Storm Water Management Facilities (SWMFS) shall be incorporated into the design of all storm drainage in accordance with the City of Virginia Beach Storm Water Management Ordinance, (SWMO) and the Storm water Management Guidance Manual, (February 1993), which is included in Appendix F; and the Design Guidance Manual for Hampton Roads-, prepared by the Hampton Roads Planning District Commission, dated December 1991, shall be used as a guideline. Final decisions on the use of this manual are to be determined by and are at the discretion of the Development Services Center and the Department of Public Works. C) All storm sewer drainage systems shall be designed to be in accordance with the Storm Water Management Ordinance (SWMO), and must restrict the developed flows to pre-existing conditions unless a regional system has been adopted for quantity and quality and the regional system has the proper easements for drainage, impoundment, treatment, etc. In such a case or in the case where the area of disturbance of the site is less than one acre, the downstream system must still be proven adequate. For land disturbance activities of less than one (1) acre, the project is exempt from the SWMO. However, all sites, subdivisions, City and private projects regardless of size must ensure adequate downstream capacity and easements even if exempt from the swmo. Revised 1/96 Storm Water Management Page 8 Public Works Specifications and Standards d) The City of Virginia Beach has developed a City Storm Water Management Study which includes the final master plan reports and remedial action plans for the major watersheds within the City. The Engineering Division of Public Works encourages all engineers to peruse the associated master plan report to obtain information which may be useful in the design of the storm water management plan for their particular site. e) All Storm Water Management Facilities (SWMFS) are subject to the SWMFs Reinspection and Monitoring Program. f) On all Storm Water Management Facilities (SWMFS) the owner shall obtain from the City of Virginia Beach and complete a "SWMF Maintenance Agreement - for Storm and Surface Water Facility and System Maintenance". Upon completing the SWMF Maintenance Agreement, the owner must record the agreement in the Clerk of Circuit Court in the City of Virginia Beach, Virginia. See Section 10.11 for the agreement. SECTION 8.1 Conformance Standards a) All underground storm sewers and open drainage ways shall be constructed according to the applicable provisions of Divisions II, III, IV, V, and VI of the Virginia Department of Transportation Road and Bridcie Specifications, (1994) and the Virginia Department of Transportation Road and Bridge standards, (1993) and the standard drawings included in Appendix A and B of this manual. b) VDOT storm drainage inlets and curbs and gutter shall be used unless otherwise directed or approved by the Department of Public Works or the City Engineer, or his designee on all right-of-ways greater than 60 feet. SECTION 8.2 Precast Drainage Structures If precast storm drainage structures, other than City of Virginia Beach or VDOT standards, are utilized, shop drawings with proper certifications, must be submitted to the Department of Public Works or Planning for approval. Page 8 - 2 Storm Water Management Revised 1/56 Public Works Specifications and Standards SECTION 8.3 Improved Properties Drainage Storm drainage of improved properties shall be designed to be adequate for the type of improvements proposed and to be designed to adequately handle the existing and projected upstream storm water runoff based on City standards and in such a manner as not to have detrimental effect on the properties of others (upstream or downstream) or the public rights-of-way. Current land use (available in the City Planning Department) shall be used for the establishment of runoff coefficients for the computation of storm water quantities. Where a conflict may exist, the highest coefficient shall be used. Drainage systems that intercept the drainage of public right-of-way shall be designed in accordance with the current publication of the Department of Public Works specifications and Standards, and Section 8.10 (Downstream Drainage) and all necessary easements dedicated to the City of Virginia Beach. SECTION 8.4 Storm Drainage Structure Information size, slope, invert and rim elevations of all proposed and existing storm drainage pipes and structures in the vicinity of the site shall be shown on the plans. (a) The minimum storm drainage pipe or culvert diameter in the City right-of-way or drainage easement shall be fifteen (15) inches. Where appropriate, a twelve (12) inch, ten (10) inch or an eight (8) inch pipe may be used as an exception when conditions dictate such as at the shallow end of the system or where conflicts exist. This is primarily intended for situations involving connections or extensions to existing systems with established geometric constraints. New storm drainage systems should not be considered for this exception to the minimum pipe size criteria. (b) The minimum storm drainage pipe or culvert diameter on-site, for means of restricting storm water runoff flows off site shall be six (6) inches. (c) Storm drainage structures are required to be placed in the storm drainage system such that the pipe distance between each structure is a maximum of 300 feet for storm drainage pipes less than 4811 in diameter. For pipes 4811 in diameter and greater the maximum distance between structures shall be 400 feet. Revised 1/96 Storm Water Management Page 8 - 3 Public Works Specifications and Standards SECTION 8.5 Storm Drainage Calculations All drainage calculations and drainage area maps shall be submitted to the City at the same time as with the submitted plan. SECTION 8.6 Storm Frequency Design criteria The design of storm drainage systems shall be based upon the following criteria: a) The "Rational Method" or other acceptable method shall be used to determine the peak storm water run-off from any site less than 200 acres. sites used to determine the rainfall intensity in conjunction with the Rational Method, and as included in Appendix E (Rainfall Intensity Chart). b) The time of concentration shall be computed in accordance with the Vircrinia Delpartment of Transportation Drainacte Manual (1980), using the Kinematic Wave Formula. d) The determination of pipe capacity should be based upon "Mannings Equation" with subsequent,backwater equations, or other methods acceptable to the City. e) Coefficients of runoff to be used are as follows, unless site specific calculations are made: TABLE VIII - 1 Runoff coefficients Area Runoff Classification Coefficient Business, Industrial & Commercial 0.90 Apartments & Condominiums 0.75 Schools 0.55 Residential (Lots 7,500 to 10,000 sq.ft.) 0.40 Residential (Lots 10,000 sq.ft. to 1/2 acre) 0.35 Residential (Lots 1/2 acre or more) 0.30 Parks, Cemeteries, and Unimproved Areas 0.20 f) Storm sewer drainage system capacities shall be designed for rainfall events having a ten (10) year recurrence frequency for streets, site plans, and subdivisions; except where the area involved is in excess of three hundred (300) acres, the rainfall return shall be increased to a twenty-five (25) year recurrence frequency. For all watersheds in excess of five hundred (500) acres, a 50 year recurrence frequency shall be used. g) All subdivision and site plan storm drainage Page 8 4 Storm Water Management Revised 1/96 Public Works Specifications and Standards calculations, for detention systems, should be computed on a minimum of a twenty-four (24) hour storm event unless a shorter duration storm is calculated or required to be calculated showing a more critical duration. h) Inlets on private and public streets shall be sized and spaced so as not to exceed a spread of ten (10) feet in the street (immediately up stream of the inlet) based on 3.5 inches per hour. Inlet capacities for four-lane divided highways and larger roadways shall be checked on grade (immediately up stream of the inlet), in a sump (immediately up stream on both sides of the inlet as well as in front of the inlet), based on 6.5 inches per hour. See the "Drainage Outline" in Appendix E. i) All subdivision residential retention and detention Stormwater Management Facility (SWMF) basins must be designed such that the 100 year storm event rise is not higher than the floodplain elevation shown on the floodplain maps adopted by the City, unless the existing ground of the subdivision where residential houses are to be built, is a minimum one (1) foot above the floodplain elevation as shown on the Federal Emergency Management Agency FIRM maps. A note shall be added to the plans that no basements shall be built or the lots lowered in any way. All wet storm water retention Stormwater Management Facilities (SWMFS) shall be a minimum five (5) feet in depth with a two (2) foot over dredge; f or a minimum depth of seven (7) feet. An as-built certification of the depth, by a Virginia Certified Land Surveyor, shall be submitted to the City for review and approval at the time of request for release of final bonds. This minimum depth is measured from the normal dry weather water elevation to the bottom of the retention basin at its lowest point. The elevation of the dry weather water level shall not be less than the 10-year high tide elevation (see Table E-14) of the downstream outfall system to prevent backflow of saltwater into the proposed retention system which would kill vegetation already acclimated to a freshwater environment. soil stabilization should be biodegradeable within vegetated areas.

PVC pipe can be used; however, the orifice equation does not apply to pipes. A backwater check will give the correct size to be equivalent to an orifice, which probably will be much larger than the orifice you would have used if using the orif ice equation. If the orif ice size calculated is smaller than six (6) inches in diameter use section 8.6 (m). M) When restricting flows on small sites (less than I cfs), to eliminate the use of outfall restricting devices less than six (6) inches in diameter, Darcy's Law for Flow and/or the following derivation of Darcy's equation may be used to restrict flows using a minimum pipe size of six (6) inches in diameter with VDOT #8 or #57 aggregate or similar restriction aggregate overlaid with #3 BMP aggregate with a minimum 1/2" x 1/2" hardware cloth attached to the pipe opening. Darcy's Law applies to storm water infiltration systems. q = kiA where; q = volume of flow passing through the stone measured in cfs k = permeability coefficient of the stone (see table below) i = hydraulic gradient (slope of groundwater or water surface through the media) A = cross-sectional area of stone TABLE VIII - 3 Typical Ranges of Permeability for Different Soil Types Soil Type Relative Degree of k, Coeff. o f Dramage Properties Permeability Pe@bility (cm/sec) Clean gravel High 1 to 10 (avg = 5) G Clean sand, sand and Me-dium 1 to 10-3 (avg = 10-) Good gravel n2ixtures Fine sands, silts LOW 10 3 to Io-' Fair through poor Sand-silt-clay Very low io@ to lo Poor through mixtures, glacial tills practically impervious Homogeneous clays Very I o w t o Less than Practically impervious p r a c t i c a I I y io-7 impermeable Revised 1/96 Storm Water Management Page 8 - 7 Public Works Specifications and Standards BMP STONE PERMEABILITY CHARACTERISTICS Aggregate Ilk" CFS per type (cm/s) 2'x 2'x 21 section 03 5 0.656 #57 4.1 x 10-1 0.054 #8 4.7 x 10-1 0.062 #50 sand (Tarmac) 3.4 x 10-2 0.0045 Manufactured sand (Vulcan) 1 x 10 -3 0.00013 Approximate value n) Infiltration and storage in the stone voids cannot be counted as the sole positive drainage discharge or as storage in the storm drainage calculations for the required ten-year storm event. Storage in the stone voids as a SWMF should only be counted in the two-year event (or first ill of runoff) SWMF calculations for water quality. A backup, bleed off pipe is required as inf iltration may decrease substantially over time. o) Infiltration systems, without storage, do not require any retention time as with dry or wet retention systems, providing the entire quantity of storm water is to be recharged into the ground as it is being received after the rainfall event has subsided based on a ten (10) year storm event. However, the downstream system must still be able to handle the pre- development ten-year (10) flows and a backup bleed off pipe is required. P) All on-site drainage required internally for the development of any proposed site improvement or subdivision shall be designed and constructed in its entirety by the developer, with appropriate consideration of the major storm systems which are serving adjacent and/or upstream properties. SECTION 8.7 Kinematic Wave Formula Runoff Coefficients The following roughness coefficients for overland flow in the kinematic wave formula shall apply in the City of Virginia Beach: TABLE VIII - 4 Roughness Coefficients Surface 'ON" Dense growth (*) .................... 0.4 -0.5 Pasture (*) ......................... 0.3 -0.4 Lawns (*) ........................... 0.2 -0.3 Bluegrass sod (**) .................. 0.2 -0.5 Short grass prairie (**) ............ 0.1 -0.2 Sparse vegetation .................. 0.05 -0.2 Bare clay-loam soil (eroded) ....... 0.05 Concrete/asphalt ................... 0.02 from Crawford and Linsley (1966) from Woolhiser (1975) Page 8 - 8 Storm Water Management Revised 1/96 Public Works Specifications and Standards SECTION 8.8 Open Drainage Systems Open storm drainage conveyance systems (i.e., ditches greater than 18", in depth) shall be piped with the development and improvement of any property. The standard for land development of site plans and subdivisions shall be the installation of underground storm systems. Land Management drainage plans are excluded from this section; see Section 11.19 of this manual for specific Land Management design criteria. a) open drainage systems and channels will be considered for approval by the Department of Public Works where culvert requirements exceed a seventy-two (72) inch diameter reinforced concrete pipe or equivalent. Open drainage systems, if approved by the Department of Public Works, shall be designed in accordance with the criteria established in this manual and in items b, c, and d below. b) open ditching is not acceptable, however, open swales systems may be approved provided they do not exceed eighteen (18) inches in depth, measured from the invert of the swale to the top of cut. Swale side slopes shall be flatter than 3:1. The minimum longitudinal slope should be 0.5% or 0.005 ft/ft., if possible. C) For design of canal, lake, SWMF retention basins and other wet drainage systems, the side slopes (including retention/detention ponds - wet or dry) must not be steeper than three (3) feet horizontal to one (1) foot vertical (3:1) as measured from the bottom to the top of bank with a twenty (20) foot drainage and maintenance strip on the top of bank of the canal. When drainage and maintenance strips are required, they shall be provided on both sides of the canal beyond the top of bank whenever the top of bank to top of bank width is thirty (30) feet or greater. see details in Appendix B drawings number B-33 and B-34 showing standards. All wet SWMF retention basins shall adhere to drawings B-33 and B-34. Bank slopes steeper than 7:1 (H:V) shall show riprap as shown or some other appropriate stabilization such as a short bulkhead or CCA treated wooden revetment, or other acceptable structural hardening to prevent erosion from wave action.. Revised 1/96 Storm Water Management Page 8 - 9 Public Works Specifications and Standards d) Whenever open channel drainage systems or swales are installed, adequate bank stabilization and erosion control measures shall be implemented in accordance with the Virginia Erosion and Sediment Control Law and Regulations (1993) and the Virginia and sediment Control Handbook, third ed. (1992); the City of Virginia Beach Ordinance 485 "Erosion and Sediment Control; and Chapter 16 of this publication. The design engineer shall inspect and classify the soil on all bank slopes graded steeper than 7:1 and recommend appropriate stabilization measures. Bank slope protection shall be installed on all wet retention/detention ponds with bank slopes steeper than 7:1, in accordance with detail drawings B-33 or B-34, as applicable, in Appendix B of this manual. Bank slopes steeper than 7:1 also require riprap or other appropriate long term hardened revetment design for stabilization at the waterline as shown on drawings B-33 and B-34, to prevent escarpments and damage from wave action at the normal waterline. e) A perimeter ditch shall be defined as any existing open drainage system located on a property line such that the boundaries for storm water runoff are contiguous to two or more adjacent properties. Perimeter ditches in subdivisions and/or site plan development must be picked up and piped with an underground drainage system. The storm system shall be sized to accommodate all existing upstream drainage and provide adequate easement for any future drainage requirements. Perimeter ditches must be piped when adjacent to developed properties. Where adjacent to undeveloped properties, residential subdivision projects must pipe the perimeter ditch also. The design engineer may propose the filling of the entire perimeter ditch instead of piping, if there will be no blockage of drainage flows on the site or adjacent properties. If the perimeter ditch is to remain open temporarily then, appropriate storm drainage inlets connected to the City's storm drainage system, every second lot line shall be provided to drain the perimeter ditch and the perimeter ditch shall be regraded to a perimeter swale until it can be filled in entirely. The regrading or partially filling a temporary perimeter swale can be waived by the reviewing engineer if substantial tree damage can be verified. f) For non-residential development, where a proposed commercial site is adjacent to an undeveloped commercial or non-residential property, the initial developer will be required to pipe one-half (1/2) of the perimeter ditch for its length along the undeveloped property at the downstream outfall location. Page 8 - 10 Storm Water Management Revised 1/96 Public Works Specifications and Standards SECTION 8.9 Subdivision Times of Concentration The City will accept the following KAXIMUM times of concentration for subdivisions TO THE FIRST INLET: TABLE VIII - 5 Subdivision Times of Concentration 181 x 801 townhouse lots (8 units/bldg) .... 10.0 minutes 181 x 801 townhouse lots (4 units/bldg) ..... 10.0 minutes 201 x 801 townhouse lots (8 units/bldg) ..... 12.0 minutes 201 x 801 townhouse lots (4 units/bldg) .... 11.0 minutes 201 x 1001 townhouse lots (8 units/bidg) .... 13.0 minutes 201 x 1001 townhouse lots (4 units/bldg) .... 11.0 minutes 751 x 751 single family lots ............... 13.0 minutes 501 x 1001 single family lots ............... 11.0 minutes 751 x 1001 single family lots ............... 14.0 minutes 1001 x 1001 single family lots ............... 15.0 minutes 1001 x 2001 single family lots ............... 16.0 minutes NOTE: if unusual situations require lower times of concentration due to grades, lot coverage, drainage layout, etc. , then calculations must be done by the developer. SECTION 8.10 Downstream Drainage The purpose of this section is to provide guidelines for requirements f or downstream improvements and easements with development. This covers all commercial site plan and subdivision development in the City of Virginia Beach. If the development is draining into a wide area of wetlands in a wide natural floodplain or watercourse, the development may continue to discharge into the downstream system at its present undeveloped rate of runof f without having an easement of record provided any increase in volume will not cause downstream or upstream damage. If the developer plans to increase the rate of runoff through the system, an easement must be obtained, even though the system may be adequate to receive the runoff. If the downstream drainage system, canal or ditch is man- made, improved by man or upstream of a wide area of wetlands in a wide natural flood plain, the developer must obtain written recorded permission (or drainage easement) to drain anv water through this downstream system. This generally applies to commercial site plans Revised 1/96 Storm Water Management Page 8 - 11 Public Works Specifications and Standards where no public water flows through the site. This applies even if the rate of flow if storm water runoff from the site is held back to existing (predeveloped) public drainage. When any water will be from public lands or rights-of-way, the City must be provided with an easement all the way downstream to a point such as a large wetlands area within a wide natural floodplain. This applies to commercial site plans and subdivisions even if the storm water outfall is held back to existing (predevelopment) conditions. Downstream improvements are not required when the storm water runoff from the site is restricted to pre-existing flow and/or is retained on-site; UNLESS the existing storm water conveyance outf all system is inadequate or is higher than that of the site outfall or unless the post- development rate or volume of runoff is greater than the pre-existing runoff. The design engineer must submit proof, of the existing downstream drainage facility capacity, to the City in the form of topographical survey; including elevations, location, size of vegetative growth within the existing ditch as well as trees, photographs, and a reasonable channel lining coefficient, along with drainage calculations, drainage area map, location map, in addition to the pre-existing flows and post-development flows. If either the review engineer or the design consultant suspect that the post- development or existing flows (rate or volume) exceed the capacity of the existing receiving outfall channel, then downstream drainage easements and downstream improvements shall be required, to a point such as a large wetlands area within a wide natural f loodplain downstream that the improvements and easements are satisfactory as determined by the Department of Public Works. SECTION 8.11 minimum Slope and Velocity in Storm Water Conveyance Systems PIPES AND CULVERTS The minimum slope in pipes and culverts should be 0. 3% or 0.003 ft/ft. VELOCITY The minimum desirable velocity of any storm drainage pipe or culvert should be three (3) feet per second based on a ten (10) year storm frequency for the design of the storm drainage system. However, it is recognized that due to the relatively flat terrain of this region, it may not always be possible to achieve this desired velocity. The maximum velocity shall not exceed the design criteria as specified by the pipe manufacturer, unless otherwise approved by the City Engineer. When the storm drainage pipe outfall is submerged, it is difficult to obtain three (3) feet per second and the design engineer should take this into consideration when designing the outfall. Page 8 12 Storm Water Management R vised 1/96 Public Works Specificati ons and Standards SZCTION-8.12 SWMF and Drainage Facility Setback Roquirements This section provides additional guidance regarding the interpretation of City Storm Water Management ordinance concerning Storm Water Management Facilities (SWMFS) drainage facility and setbacks. This section applies to all proposed SWMFS, drainage ponds, Storm Water Management Practices, retention basins (wet ponds), detention basins (dry ponds), infiltration trenches (including open and rock f illed) , swales, ditches and any similar storm drainage facilities such as trenches f or storm drainage pipe which may damage the property of others. This section also applies to the above drainage facilities if they were existing and a new property line is being created near them. a) DEFINITIONS: 1. WET POND or LAKE - Any pond of storm water which has a permanent pool of water in the bottom. The Storm Water Management Ordinance designates this normally as a retention basin. 2. DRY POND - Any pond of storm water which does not have a permanent pool of water in the bottom and is usually dry unless there is a storm event. The Storm Water Management Ordinance designates this normally as a detention basin. 3. DEPTH TO WATER - Vertical height measured from the top of bank at existing or proposed ground to normal, dry weather water surface elevation. 4. DEPTH OF WATER - Vertical height measured from the normal dry weather water surface elevation to the bottom of the retention basin (wet pond). 5. DEPTH OF DRY POND, DETENTION BASIN, DITCH BASIN, ETC. - Vertical height measured from the highest existing or proposed surface elevations to the bottom of the lowest proposed excavation or existing depression. 6. SETBACK - Horizontal distance measured from the property line or right-of-way line to the top of bank of any detention basin, retention basin. Revised 1/96 Storm Water Management Page 8 - 13 Public Works Specifications and Standards 7 Linear Development Projects - The exemption for Linear Development Projects does not mean that City highway projects, private development highway, street development, or subdivision projects are exempt (see conditions and definitions in Sections 4 and 5 of the SWMO.) 8. Receiving Bodies of Water - is all inclusive as defined in Section 4 of the SWMO from the smallest subarea and subwatershed through the entire system, downstream to the Chesapeake Bay, Back Bay, North Landing River, the Atlantic Ocean, etc., regardless of the design or type of drainage system. b) SWF and Drainage System Setback Facility Considerations The Public Works Engineering or Planning review engineer shall consider the following items when determining or recommending SWMF setbacks: 1. Type of SWMF Basin or Drainage System: a) WET (Retention) - Should maintain a minimum 20-foot wide strip around the entire wet pond beyond top of bank f or construction, dredging, and maintenance. b) DRY (Detention) - Requires access from at least one side of the dry pond with a 15- foot preferred setback from the property line depending on what property of others might be damaged. This will not necessarily require a waiver to the Stormwater Management Ordinance. Review engineer may need approval from City Engineer or may need a waiver to the Stormwater Management Ordinance, depending on the judgement of the review engineer. C) EXISTING POND SWMF or Drainage Facility - To be expanded in the future. A new property line being created nearby will not require a variance to the Stormwater Management Ordinance. 2. Items on or adjacent to the property line (both sides) which may be damaged during construction or future maintenance: a) Mature trees and their root spread b) Saplings C) Other landscaping including bushes d) Buildings e) Fences f) Highly erodible soils Page 8 14 Storm Water Management Revised 1/96 Public Works Specifications and Standards 3. Future improvements a) Capital Improvement Projects b) Expansion of right-of-way improvements C) Future construction within adjacent properties - particularly future residential use 4. Any other unusual situations C) Subsection 9 of the Storm Water Management ordinance is interpreted as follows: 1. All retention basins (wet ponds) shall meet the setbacks in accordance with the Stormwater Management ordinance unless a written variance request is obtained. See subsection b above. 2. Setbacks for detention basins (dry ponds) more than six (6) inches deep but less than eighteen (18) inches deep shall be located at least five (5) feet away from any existing exterior property line and at least five (5) feet from any existing and/or proposed right- of-way lines of public streets and/or highways. Dry ponds more than eighteen (18) inches but less than thirty-six (36) inches deep shall be at least ten (10) feet from all existing exterior property lines and at least ten (10) from all right-of-way lines of public streets and/or highways. Dry ponds between thirty-six (36) inches deep and sixty (60) inches deep shall be located at least fifteen feet (15') from all existing exterior property lines and at least fifteen (15) feet from any existing or proposed right-of-way lines of public streets and/or highways. 3. The setbacks for all proposed swales, infiltration trenches and other drainage excavations, no more than 18 inches deep to the bottom of the excavation can be approved by the review engineer down to zero feet from the property line if no damage to property of others will result, taking into account considerations listed in Section b above. 4. If in doubt as to whether any of the above SWMFs or drainage facilities are too close to the property lines or may cause property damage, the review engineer shall request assistance from the City Engineer or his designee or process a variance in accordance with Section 5 of the Storm Water Management ordinance. Revised 1/96 Storm Water Management Page 8 - 15 Public Works Specifications and Standards 5. Ponds, borrow pits, SWMFs greater than a minimum 1/4 acre should provide adequate space adjacent to them for spoil facilities (needed for maintenance) ; or an easement on a park site and a minimum of two access/pumping easements along appropriate lot lines, ten (10) foot minimum in width. d) Variance requests 1. Variance requests, recommendations and replies shall be in writing to document the reasons for the decisions made in accordance with Section 5 of the storm Water Management ordinance. 2. Variance requests will be accompanied by photographs taken by the person requesting the variance to document the conditions in the field. A plan shall accompany the photographs, indicating where, when, and in what direction the photographs were taken. 3. The variance recommendation will be prepared by the review engineer and forwarded to the Development Services Center for review and approval or denial by the Director of Planning. 4. The response to the variance should be provided to the customer within 30 working days, unless additional issues or questions arise. SECTION 8.13 Rear Lot Drainage in Multi-Family Dwellings This section pertains to all new townhouse developments in the city of Virginia Beach, including condominiums and/or apartment developments that are constructed similar to townhouses. a) Positive drainage is required in all townhouse developments, with outlets for rear lot drainage between all buildings. b) Easements along rear iot and side lot property lines are to be dedicated as "Drainage/Pedestrian Easements" and must be a minimum of five (5) feet wide on each side of property lines. Page E Storm Water Man gement R vised 1/96 Public Works Specifications and Standards C) Concrete swales or combination concrete swale/pipe systems are required within rear lot and side lot drainage easements in accordance with City of Virginia Beach Department of Public Works standards. All concrete swales and combination concrete swales and pipe systems are to be designed and constructed with a minimum of 1/2 percent (1/2% or 0.50%) longitudinal slope, on new construction. This may reduce slightly only for good reason which shall be documented in the file. d) Concrete swales or combination swales and pipe drainage systems are to be installed prior to issuance of occupancy releases on all affected lots. e) No encroachments will be allowed within the drainage/pedestrian easements. f) Private utility lines may be allowed within the drainage/pedestrian easements if installed in accordance with the city of Virginia Beach Department of Public Works Standards. g) Request for variances to this policy must be submitted in writing for consideration by the Director of Public Works. h) Drainage in the rear of apartments, townhouses, or any multi family dwelling of more than two units per building structure must have some type of paved swale and two yard inlets, one at each end of the units of the structure. PVC pipe and PVC type inlets, or 12-inch half-round concrete pipe will be allowed. These must be installed prior to release of any units for occupancy. SECTION 8.14 Impoundment Easements A City drainage and impoundment easement must be recorded by plat over the entire lake, pond, drainage system, retention basin, detention basin or other SWMF and the following note must be shown on the plat where City or public waters or stormwater runoff flows through or into such drainage storage or SWM Facility. "Drainage and Impoundment easement is hereby dedicated to the City of Virginia Beach for all of the following, but not limited to, conveyance, storage, drainage, impoundment, treatment and other related uses of surface and/or ground water as described in the deed of easement recorded herewith. No alterations whatsoever of the lake and its bank side slopes within the limits of the Revised 1/96 Storm Water Management Page 8 - 17 Public Works Specifications and Standards drainage and impoundment easement is permitted without the approval of the Department of Public Works. city maintenance shall be limited to that as described above.of A twenty (20) foot maintenance easement as measured from the top of bank shall be platted around the lake and dedicated to the City. SECTION 8.15 Stormwater Management Facilities (SWMP) Stone All BMP stone size shall be "City of Virginia Beach #3 SWMF aggregate" or equal as approved by the Department of Public Works. SECTION 8.16 stormwater management Facilities (SWMF) Bond All associated storm drainage facilities, which are part of the BMP, must be bonded as part of the SWMF, in the Stormwater Management and Erosion Control Bond. All SWMF Bonds must meet the permit criteria set forth in Section 9.3 of this publication. SECTION 8.17 Storm Sewer Pipe Termination All storm sewer pipes dead-ending at the upstream end and/or leading from a gravel infiltration system or gravel inlet structure must have an acceptable filter fabric around the end of the pipe or the pipe must be plugged with concrete to keep silt from entering the pipe system. SECTION 8.18 Stormwater Management Facilities (SWMF) Considerations a) All SWMFs must design a minimum distance of three (3) feet separation between the edge of the SWMF and the edge of any building foundation. b) Infiltration and/or dry Detention Basin SWMFs must have a minimum separation distance of two (2) feet between the seasonal (adjusted) high water table elevation and the bottom of the infiltration trench. The consultant shall establish the seasonal (adjusted) high water table elevation based on good engineering practices. C) Filter fabric should not be wrapped directly around perforated pipe or risers. The fabric restricts flow by a factor of 8 to 15 over free flow through an orifice. Instead, wrap the fabric around the #3 SWMF stone placed around the perforated pipe or riser. Page 8 18 Storm Water Management Revised 1/96 Public Works Specifications and Standards d) over excavation (beyond 15 feet deep and/or beyond the horizontal or vertical limits shown on the approved plans) of dry ponds or wet ponds will not be permitted, without prior written approval by the City Engineer or the Development Services Center. e) The minimum stone depth for infiltration structures shall be eight (8) inches. f) All special and/or modified drainage structures for SWMFs shall be clearly and completely detailed with all necessary notes and dimensions for construction. This detail must be included on the plans. Modified structures must correlate with current City of Virginia Beach Standards and Specifications or Virginia Department of Transportation Standards and Specifications including all applicable notes, specifications and references. g) Subdivisions that require Stormwater Management Facilities (SWMFs), in the case of Land Management Drainage Plans for septic tanks in poorly drained soils, the SWMFs shall be separated from the land management ditches which drain the septic tank(s) drainfields. The SWMF outfall should be constructed upstream of the land management outfall to ensure "flushing" of the land management runoff and to not create any backflow conditions or septic conditions in standing water which could cause a health threat to the public. Generally, single family land management plans do not require a SWMF because there is not increased stormwater runoff. However, all land management plans require downwtream drainage easements to avoid health problems from blockage of the downstream drainage system. h) Volume control SWMFs will not be permitted within the public right-of-way or designed with subdivision development within the right-of-way unless approved by the City Engineer. If these volume control SWMFs are used in the right-of-way then pipes and outfalls shall be designed for a standard ten (10) year flow (or more if applicable). SECTION 8.19 Stormwater Management Facilities (SWMF) AS-Built Drawings SWMF as-built drawings are required for all wet and dry detention and retention ponds constructed within the City of Virginia Beach. These drawings shall be submitted to the City in accordance with the criteria in these specifications and standards, Section 11.6. Revised 1/96 Storm Water Management Page 8 - 19 g Public Works Specifications and Standards SECTION-8.20 Narking Underground Stormwater Management Facilities (SWMFs) All underground SWMF facilities must be marked with a 5" x 5" x 1/4" or larger steel plate at each corner or marked with white metallic marking tape, 3" wide, placed on top of the SWMF, not to exceed one f oot below the ground surface. In certain cases, at the option of the City Inspector, it may be appropriate to use both. All underground storm drainage, water and sewer pipes (non-metallic, or concrete) in the City right-of -way must be marked with white (or other appropriate color) metallic marking tape, 3" wide, placed above the facility, not to exceed one foot below the ground surface. SECTION 8.21 Storm Water Floodplain Storage Guidelines In designing and reviewing proposed activity within the floodplain in conjunction with storm water storage requirements, the following shall be considered along with Section 5B of the Site Plan ordinance pertaining to floodplain regulations: a) Maintenance of Flood Storage Capacity To assure that flood storage capacity is not decreased, the review engineer shall require that there be no net movement of fill material from outside the floodplain limits to inside the floodplain limits. He may allow, however, transfer of material from one part of the floodplain to the other provided that neither conveyance nor storage capacities are adversely affected and all other guidelines contained herein are adhered to. b) Storage Capacity for Lesser Storms The requirement to maintain flood storage capacity shall be construed as applying not only to the 100- year storm but to all storms of lesser intensity as well. Therefore, in regard to movement of material within the floodplain, the net movement of material shall be from a lower to a higher elevation within the floodplain, and not the reverse. In no case shall movement of material be allowed which decreases flood storage capacity for storms of less than 100-year intensity. The bottom of any excavation in the floodplain shall be at +3.0 ft. (m.s.l.) or above or at -4.0 ft. (m.s.l.) or below to avoid creation of mudflats. Page 8-- 20 Storm Water Management Rev sed 1/96 Public Works Specifications and Standards C) (Lakes, Wet Ponds), Retention SWMFS: Excavation of lakes within the floodplain in order to create additional storage capacity will be allowed, except that the capacity created shall be measured by the volume created above the normal water outfall elevation. Lakes excavated outside of the limits of the floodplain shall not be figured in the measurement capacity. It must be noted that the normal water elevation of Back Bay and the creeks is 1.0 ft. (m.s.l.) and the level of water at the start of a storm is 2.0 ft. (m.s.l.) or that as recommended in the Camp Dresser McKee Drainage Study of the City, whichever is higher. d) Effect on Storm Water Flow Conditions In order to assure compliance with the requirements of this section with respect to storm water flow conditions, it shall be assumed that natural flow conditions are optimum, and any deviation from natural state shall be the minimum necessary. SECTION 8.2 Retention (Wet) and Detention (Dry) Stormwater Management Facility (SWMF) Design Guidelines The purpose of this section is to provide a guide f or the design, review or construction of retention and detention basins. An understanding of retention and detention basin facilities is a key factor in the development of a complete storm water management plan. This section provides a cursory review of topics to consider when analyzing retention and detention basins. It is recognized that retention and detention Stormwater Management Facilities (referred to as SWMFs in this manual and in the SWMO) are designed on a site-specific basis and that innovative designs are encouraged. it should be noted that a hydrologic analysis, detailing peak flows, allowable flows and system capacities, must be performed in conjunction with the design of any SWMF. The City of Virginia Beach has adopted a Storm Water Management Ordinance, and the information within this section in no way supersedes or alters the requirements contained in, or the spirit of, that ordinance. Retention (wet ponds) and detention (dry ponds) are the temporary storage of stormwater runoff, where the discharge is released at a predetermined and controlled rate. Storage begins when the flow into a system exceeds the flow out of the drainage system. A properly designed and constructed SWMF will attenuate peak runoff rates, decrease soil erosion, allow settling of solids and improve water quality. @evisea i/96 Stor ement Page 8 - 21 Public Works Specifications and Standards When development occurs, whether site, subdivision, or highway, storm water runoff rates are typically increased above the pre-developed rates. The Stormwater Management ordinance requires that f lows from development not exceed the peak pre-development rates. This requirement is most commonly met by designing and providing a SWMF basin. A thorough design should include consideration for the hydraulic characteristics, water quality, safety, aesthetics, and maintenance of the system. It is recognized that not all of the following items can necessarily be incorporated into the detention pond design, however, it is recommended that as many items as practical be utilized. a. Hydraulics The peak post-development discharge rate from a detention pond is limited to the peak pre- development runoff rate at the pond's outfall. When determining the pre and post-development runoff rates, the time of concentration (Tc) and travel time (Tt) is the most important controlling factor. Due to a number of variables, time of concentration can be a difficult parameter to determine. Accurate time of concentration calculations must be performed to properly size a detention pond. The longest Tc to a detention pond should be used in most cases unless the drainage area is of unusual width to length proportions, and then the Tc can be measured accordingly for design. When measuring drainage areas, the area of the retention basin itself is considered 100% impervious, as it represents direct rainfall contribution to the system. SWMFs should be designed for any future development within the watershed of the project. Larger retention "wet" systems are more efficient from the perspective of construction cost, maintenance cost, and land requirements, and may be better suited to meet the standards and requirements of the Storm Water Management ordinance. Additional development may be limited by a facility that was previously under designed for future expansion. The hydrologic and hydraulic properties of the ultimately developed watershed must also be considered. This often means determining the future land use and its time of concentration of Page 8 22 Storm Water Management Revised 1/96 Public Works Specifications and Standards percent impervious area. For any such assumptions, it is wise to be conservative. Course-C, the Pagan Method and the Waller Method are popular methods for approximating detention storage volume requirements. These methods may be used for small sites (5 acres or less) . These methods are conservative when an orifice or culvert is used to restrict discharge rates. Conversely, they are not conservative, and should not be used, when a weir or multi-stage outlet is controlling the outflow or when the drainage area exceeds the limitations of the intended design method. Numerous methods for actual storm routing exist and each method will be reviewed on a case by case basis for the individual project by the Department of Public Works as to its acceptance and applicability. The SCS National Engineering Handbook, Section 2, "Hydrology" should by used when preparing the reservoir routing, calculations by hand. The following computer programs are accepted for use in the City for reservoir routing: SCS (TR-20 OR TR-55) , FHWA-Hydrain, EPA-SWMM, Haestad Methods - Pond Pack, Muncaster Engineering - Muncaster Hydrograph/Routing, Small Pond (for areas less than 5 acres) , and ICPR or other similar computer programs. The downstream system from a SWMF must always be considered in the design process. Detention ponds extend peak runoff rates beyond the pre-development duration. This presents two problems that are often overlooked. First, the downstream system may be subject to erosion. If the existing conveyance system is inadequate, additional stabilization measures may be required. Second, the extended peak may meet a peak from another watershed and cause damaging flooding. Cumulative hydrographs can cause excessively high peak flows under certain conditions. A proposed facility's runoff timing should be checked against the natural and developed characteristics of the full watershed. If the downstream system is sensitive to timing, the proposed SWMFs outflow may have to be reduced to duplicate the cumulative peak flow in the downstream system. Revised 1/96 Storm Water Management Page 8 - 23 Public Works Specifications and Standards SWMFs are typically required to be designed for at least the 2-year (2) and ten-year (10) storm frequency, depending on the number of acres in the watershed. The two (2) year event should also be checked for compliance with the Virginia Erosion and Sedimentation Control Regulations, (1993) , and for storm water quality objectives. A facility will operate correctly at a single design condition if only one design storm is considered. Often, only minor adjustments to the outlet structure are required before a complete agreement between actual and calculated discharge rates exist. When the total cost of a facility is considered, including overall maintenance, the additional design effort is justified if full protection for a variety of storm events is provided. SWMF basin location is a consideration in all phases design for hydraulics, water quality, safety, maintenance, aesthetics, etc. Often if SWMF basins process flows from outside watersheds, these systems become excessively large and costly, and should be avoided. SWMFs should be located so that they operate by gravity, i.e. without the aid of mechanical pumps. If a SWMF basin is located within a flood zone, it's operation may be adversely affected by flood waters. It is recognized that areas typically designated for retention or detention facilities are undesirable or unbuildable; however, this does not release a developer from providing a functional system. The normal dry weather water surface elevation of a retention basin shall not be below the ten-year (10) high tide of the downstream system (see appendix E) to avoid vegetation die-off due to saltwater inundation. Outlet structures control the hydraulic function of SWMFs. Typically, an outlet control structure is a multi-stage device which regulates discharge rates to simulate the pre-developed condition. Discharge from a well designed system does not exceed the pre-development rate for all storm frequencies up to and including the design storm required by ordinance. Outlet structures are most commonly comprised of a combination of orifices, pipes and weirs. The hydraulic performance of an outlet structure is the sum of it's staged outlets at a given water elevation. Numerous equations, charts and nomographs are available to determine their hydraulic capacities. Tailwater conditions must Page 8 - 24 Storm Water Management Revised 1/96 Public Works Specifications and Standards always be considered when analyzing the hydraulic performance of an outlet device. Many factors such as annual high tides, seasonal groundwater, and flood elevations will all affect tailwater elevations. Outlet structures should be equipped with an emergency overflow designed so that parking lots and buildings do not flood. Outlet control structures should be designed to discourage clogging. Floating or suspended debris will easily plug an unprotected outlet, which is a problem during less frequency storms when debris is washed through drainage systems. Trash racks, if designed and installed properly, can effectively protect against clogging. Trash racks usually consist of metal grates placed over an outlet structure. A good rule of thumb is that the total area of a rack's openings should be at least ten (10) times greater than the area of the outlet it is protecting. The clear openings in the grates should be smaller than the diameter of the outlet. Trash racks should also be sloped at a 45 degree angle to prevent trapping objects or persons against it. A hinged rack allows for easy maintenance and cleaning of the outlet. Another type of outlet control device is a riser pipe. Typically, it is a corrugated metal pipe set vertically near an outfall. Small holes drilled in the sides of the pipe regulate the normal outflow, with the top of the pipe accommodating less frequent storms. If the flow into a riser pipe is large, vortexing and erosion may occur. Baffles around a riser pipe help to minimize vortexing and scouring around the pipe. Depending upon the outlet device, washed gravel can be piled around small diameter pipes or orifices to discourage clogging due to sediments in the storm water. Regardless of what type of outlet control structure is selected, it should be located so that it is accessible for maintenance. It should also be a permanent structure that is not easily removed or vandalized. b. Water Quality SWMFs must comply with the Stormwater Management Revised 1/96 Storm Water Management Page 8 - 25 Public Works Specifications and Standards Ordinance, Southern Watersheds Management Ordinance and the Chesapeake Bay Preservation Area Ordinance for water quality protection. Retention and detention basins can be very effective at removing pollutant laden suspended solids from stormwater. For a more detailed description of Stormwater Management Facilities (SWMF) requirements in Virginia Beach, see (SWMF) Requirements and Design Guidelines in Appendix F. A few simple design methods can help to maximize a SWMF's ability to improve water quality. Long narrow basins with inflow and outflow points at opposing ends, discourage short circuiting, decrease velocities and increase detention time, which encourages settlement of suspended particles. Rip-rap and flattened pipe slopes at inlets decrease the inflow velocities, helping to reduce resuspension of settled particles. A two (2) or three (3) fps velocity (partially submerged) at inflow points into the pond is recommended. Benching (if required) should be constructed, sloping at 10:1, in the first twenty feet of a detention pond's littoral zone below the normal water elevation. Benching promotes the growth of aquatic vegetation, which aid in the uptake of nutrients from the storm water. Forebays, benches and wetland vegetation are an integral part of a sound storm water management plan, and should be included with the design of detention ponds. Creating new wetlands, in conjunction with storm water management facilities, has been found to significantly improve the quality of storm water runoff, and frequently have added benefit of necessitating 404 permits to perform maintenance. Therefore, before creating new wetlands it is imperative that the designer ensure that the new wetlands will not require any permits to perform maintenance. If a pond discharges into the headwaters of a stream, special precautions may be required. SWMF basins typically discharge unnaturally warm water during the summer months. Fish living in headwaters can be killed if their surrounding water temperature is elevated. If a SWMF basin discharges into sensitive waters, all appropriate regulatory offices having jurisdiction should be contacted. One possible alternative is to draw cooler water from the bottom of a SWMF basin and/or oversize the permanent pool. Page 8 - 26 Storm Water Management Revised 1/96 Public Works Specifications and Standards Protecting SWMF basins from erosion and sedimentation during construction is critical, so that the function of the system is maintained. A silted detention pond can become detrimental to the environment it was designed to protect, if it is regularly releasing sediments which accumulated during construction. SWMF retention basin and drainage system side slopes and banks should be sodded immediately after the banks are graded, regardless of the overall site's construction schedule or progress. Sodded banks trap sediment in overland flow and help to control rutting and erosion. Detailed construction sequencing and erosion control details should be clearly specified on the erosion control plans. A good erosion and sediment control plan goes beyond straw bales and silt fence and includes such measures as check dams, stilling basins, diversion berms, etc. Construction projects which release sediments are responsible for damages and can be forced to restore spoiled downstream systems. Proper erosion control planning, installation, and maintenance can save a contractor and the City both time and money if adequately maintained. c. Safety The creation of SWMF retention basins (wet ponds) and the storing storm water in these ponds may produce potential safety hazards. The location and use of ponds dictate the extent of required safety measures. Ponds located in or near residential neighborhoods may create a greater hazard potential than one located in industrial areas. All basins should be designed to the greatest extent to fully eliminate as much of a hazard as practicable. Designing bank slopes at 4:1 or flatter and incorporating benching could prove beneficial. Any slope steeper than 7: 1 (H:V) must incorporate the requirements of section 8.8 and drawings of B-33 and B-34 for soil evaluation or other structural hardening for a revetment design. Revised 1/96 Storm Water Management Page 8 - 27 Public Works Specifications and Standards Trash racks and grates can be designed to reduce the chance of a person getting trapped or stuck in a drainage structure. When a basin is accessible to the public, fences can be installed around wingwalls and steep dropoffs. Gently sloping safety benches, where a person can stand, may be located in the first twenty (20) feet of water around the shorelines. Many detention and retention ponds utilize an earthen berm which acts as a dam to impound storm water. Seepage collars around discharge pipes reduce the chance of failure due to washout. Pipe joints located within a berm or any fill must be sealed to prevent leakage and undermining. Additionally, the area downstream from proposed basins must be studied to determine the possible dangers should a berm fail. Even the most carefully designed outlet .systems are susceptible to clogging. Emergency overflows must be provided to pass flows caused by clogging or infrequent storms. Weirs are typically used to manage overflows. They should be designed to operate at 0.5 to 1. 0 feet of head. One foot of freeboard between a pond's maximum water elevation and the top of bank is desirable at the peak rise during the 100 year storm event. Ponds located in residential areas must be incorporated into the residential lots, with the appropriate City drainage impoundment easements provided. An agreement to have the property owners maintain a lake/pond is required only on commercial site plans where no City drainage easement will be obtained. d. Maintenance Detention ponds and retention basins are not maintenance free. All types of basins will need periodic cleaning. An accessible twenty-(20) feet wide area around the basin should be provided for the operation of maintenance equipment. A twenty- foot (20) wide maintenance easement around the top of the basin must be dedicated to the City where a Page 8 - 28 Storm Water Management Revised 1/96 Public Works Specifications and Standards City drainage/impoundment easement is required. Large facilities may need to be cleaned with a dragline and a spoil area will be dedicated to the City. The spoil area easement is to be a minimum equal to 10% of the area of the lake. It shall be shown on the subdivision plat in an open area such as a park or other open space unencumbered by trees and structures. Each subdivision will be evaluated individually. The spoil can be pumped up to 0.5 mile from the lake access easement and a City site in the vicinity may be considered. Twenty-foot wide access easements to the lake shall be dedicated to the City, one for every five (5) acres of lake. A fee in lieu of a spoil easement may be accepted if approved by the PW/Operations Office based on a plan to acquire a centralized regional easement. This does not apply to lakes on individual sites (unless City water flows into it since the owner is responsible for the maintenance. Detention and retention basins should be designed to operate without moving parts such as sluice gates, pumps or valves. A method for completely draining ponds by gravity is desirable. Outlet devices and other structures must be constructed of reinforced concrete or heavy gage steel. Bolting appurtenances in place discourages vandalism. e. Aesthetics Minor improvements can turn a basin into a site amenity rather than a liability. Aesthetics are especially important when a basin is located in a residential district. An attractive facility helps to lessen public opposition. SECTION 8.23 STORMWATER MANAGEMENT FACILITIES (SWMF) Monitoring Wells Monitoring wells shall be installed for all non residential infiltration SWMFs, a minimum of one between each drainage structure and/or a minimum of two installed in each SWMF, at the direction of the City's Inspector. SECTION 8.24 Development Adjacent to the City of Norfolk When development is occurring within the watershed boundaries of the City of Norfolk's lakes used for water supply, the following guidelines for stormwater management facilities prepared by the City of Norfolk shall be adhered to, in order to protect the drinking water supply.

SECTION 8.25 Water quality a) Water quality in the City of Virginia Beach should be in accordance with the STORM WATER MANAGEMENT GUIDANCE MANUAL, prepared for the City of Virginia Beach NPDES Storm Water Permitting Project, and the Best Management Practices, Design Guidance Manual for Hampton Roads, Hampton Roads Planning District Commission (1991) b) Proposed storm drainage pipe inverts shall be located at or above the elevation established for permanent pool, wet retention water quality dead storage volumes. c) Water quality dead storage volume below normal water at the outfall elevation (dead storage) will not be counted towards the two-year (2) and ten-year (10) storm event retention or detention storage requirements. Infiltration shall not be relied on to lower water levels below the invert elevation of the outfall system. d) Water quality storage may be considered, if necessary, in the stone voids but not above the invert elevation established for the storm drainage outlet structure. Generally, utilize 1" over the impervious area for determining the water quality volume required per site. (See Appendix F) . Volume in stone voids, below the outfall invert elevations, shall not be used for or counted towards the 2-year and 10-year water quantity storage required to reduce stormwater outflow rates to predeveloped flows. SECTION 8.26 Storm Water Utility-Fee Adjustment All developed sites discharging storm water runoff into the City storm sewer system or to bodies of water within the City, either directly or indirectly, will be charged a fee in accordance with Chapter 39 of the Code of Virginia Beach pertaining to the Storm Water Management Utility. a) Any existing developed site may request a fee adjustment based upon savings to the utility resulting from the on site storm water management Revised 1/96 Storm Water Management Page 8 - 31 Public Works Specifications and Standards facility in accordance with the Storm Water Utility-Fee Adjustment Policy.

Revised 1/96 Storm Water Management Page 8 - 37 11 Public Works Specifications and Standards If the application for utility fee adjustment is based on-site SWM facilities, information substantiating that the facilities meet the criteria, contained herein, for optimal design, construction, and maintenance must be included with the application. Minimum information will typically include as- built survey information, engineering calculations, inspection and maintenance records and plans and schedules for the continued inspection and maintenance of the SWM facilities. Engineering calculations documenting compliance with SWM facility design and construction criteria must be prepared and stamped by a professional engineer or land surveyor class B licensed to practice in the Commonwealth of Virginia, unless waived by the City Engineer. Section 4. Criteria for Storm Water Management Facilities Information provided with the application for storm water management utility fee adjustments must substantiate that the on-site storm water management facilities were designed in accordance with Department of Public Works design standards and/or the Virginia Storm Water Management Regulations, were constructed in accordance with the design, and are maintained in proper working order. Department of Public Works design standards are summarized in Table 1. All fee adjustment requests must include the date of construction of the SWM facilities; inspection and maintenance records for the SWM facilities; and a plan and schedule for the continued inspection and maintenance of the SWM facilities. Minimum criteria for optimally designed and constructed SWM facilities are: A. Wet Detention Ponds An optimally designed and constructed wet detention pond shall have a permanent pool of water with volume based on an average hydraulic residence time greater than or equal to 2 weeks. Table 2 summarizes the storage volume (inches per acre of drainage area) for the permanent pool of the wet detention pond required by this criteria. The required storage volume (cubic feet) is computed by multiplying the required wet detention (inches) by the total area draining to the wet detention pond and multiplying that sum by the conversion factor 3 , 630. Page 8 - 38 Storm Water Management Revised 1/96 Public Works Specifications and Standards Alternatively, the wet pond may have a permanent pool volume no less than three (3) times the water quality volume. The water quality volume is defined as the volume equal to 0. 5 inch of runoff multiplied by the total area draining to the SWM facility. The depth of the permanent pool shall be between 3 and 15 feet; the distance between the pond inlet(s) and outlet(s) shall be maximized to prevent short-circuiting of storm water flows (minimum length/width ratio of 2 : 1) ; the side slopes of the wet detention pond shall be gradual enough to prevent erosion, facilitate maintenance, and promote vegetative growth (5H: 1V or flatter preferred; 3H: 1V steepest acceptable) ; and other criteria to assure optimal functioning may be required. Note that the length is defined by the distance from the inflow point to the outflow point and width is defined as the surface area divided by the length. Survey information substantiating these criteria shall be required. The maximum utility fee adjustment (reduction) for a property utilizing optimally designed and constructed wet detention ponds for the total area of the property will be 30% of the property's total number of equivalent residential units (ERUs) , unless greater proportional savings to the utility are substantiated by the property owner. Partial fee adjustments; i.e. , less than 30%, may be made where a wet detention pond serves less than the total area of the property, provided it is optimally designed and constructed for the partial area of the property served by the wet detention pond. In such case the partial adjustment (percent) , if allowed, will be equal to the ratio of partial area served by the optimally designed and constructed wet detention pond to the total area of the property multiplied by 30%. Fee adjustments, full or partial, will not be allowed for wet detention ponds whose permanent pool volume is less than the required permanent pool volume or that fail to meet the other criteria. However, wet detention ponds not meeting the criterion for permanent pool volume may be considered for fee adjustment request purposes as dry basins, if meeting the other criteria for wet ponds and the criteria for dry basin optimal design and construction, with the exception of the permanent pool. B. Dry Detention Ponds An optimally designed and constructed dry detention pond shall have extended detention such that the water quality Revised 1/96 Storm Water Management Page 8 - 39 Public Works Specifications and Standards volume (or greater) or the volume obtained through the use of Table 3 shall be detained and released over 24 hours and preferably 30-hours. Detention time shall not exceed 72 hours. The 24-hour detention time shall begin at the time of peak storage of the water quality volume in the dry detention pond and end upon the complete dewatering of the dry detention pond. However, if this requirement would result in an outlet opening area less than 7. 1-square inches (3 inches in diameter or equivalent) , then the 24-hour detention time shall be waived to the extent necessary so that 7. 1-square inches will be the smallest outlet area necessary. The distance between the dry detention pond's inlet(s) and outlet(s) shall be maximized to prevent short-circuiting of storm water flows (minimum length/width ratio of 2 : 1) ; the side slopes of the basin shall be no steeper than 3H: 1V, and preferably no steeper than 5H: 1V; inlet and outlet protection, such as rip-rap, shall be utilized; stabilized low-flow channels shall be utilized to prevent standing water; other criteria to assure optimal functioning may be required. Note that the length is defined by the distance from the inflow point to the outflow point and width is defined as the surface area divided by the length. Survey information substantiating these criteria shall be required. The maximum utility fee adjustment (reduction) for a property utilizing optimally designed and constructed dry detention ponds for the total area of the property will be 20% of the property's total number of ERUs, unless greater proportional savings to the utility are substantiated by the property owner. Partial fee adjustments; i.e. , less than 20%, may be made where a dry detention pond serves less than the total area of the property, provided it is optimally designed and constructed for the partial area of the property served by the dry detention pond. In such case the partial adjustment (percent) , if allowed, will be equal to the ratio of partial area served by the optimally designed and constructed dry detention pond to the total area of the property multiplied by 20%. Additionally, partial fee adjustments may be allowed for dry detention ponds that do not meet the 24-hour detention time criterion. Where the full detention time is less than 24 hours, the ratio of actual detention time to 24 hours will be applied to the adjustment that would have been allowed with a 24-hour detention time; except that no adjustment will be allowed if the detention time Page 8 - 40 Storm Water Management Revised 1/96 Public Works Specifications and Standards is less than 12 hours. However, in cases where the detention time is shown to have been reduced solely to meet the minimum outlet size criterion, and all other criteria are met, the allowed fee adjustment will not be reduced by the actual detention time to the 24-hour detention time ratio. Fee adjustments for dry detention ponds with detention times greater than 24 hours but less than or equal to 72 hours will be based on a 24-hour detention time. Fee adjustment, full or partial, will not be allowed for dry detention ponds not meeting these criteria. C. Infiltration Facilities Optimally designed and constructed storm water infiltration facilities shall have sufficient infiltration capacity to fully exfiltrate the water quality volume into the underlying soil in no more than 72 hours. The floors of infiltration facilities shall be an absolute minimum of 2 feet above the seasonally high groundwater level and preferably 4 feet above. The underlying soil shall have an infiltration rate of at least 0.5 in/hr. Infiltration facilities shall be surrounded by vegetated buffers. Soil information, including infiltration rate and soil type(s) , and seasonally high groundwater elevation information shall be required. The maximum utility fee adjustment (reduction) for a property utilizing optimally designed and constructed infiltration facilities for the total area of the property will be 20% of the property's total number of ERUs, unless greater proportional savings to the utility are substantiated by the property owner. Partial fee adjustments; i.e. , less than 20%, may be allowed where a storm water infiltration facility serves less than the total area of the property, provided it is optimally designed and constructed for the partial area of the property served by the storm water infiltration facility. In such case the partial adjustment (percent) , if allowed, will be equal to the ratio of partial area served by the optimally designed and constructed storm water infiltration facility to the total area of the property multiplied by 20%. Fee adjustments, full or partial, will not be allowed for storm water infiltration facilities not meeting these criteria. Revised 1/96 Storm Water Management Page 8 - 41 i I Public Works Specifications and Standards D. Other Storm Water Management Facilities Fee adjustments for vegetative practices, oil/water separators, and other water quality inlets designed and constructed in accordance with methods recognized in the technical literature, such as "Controlling Urban Runoff: A Practical Manual for Planning and Designing Urban SWMFs" , may be allowed upon review and approval of supporting engineering calculations and documentation submitted with the fee adjustment request. Vegetative practices, in particular, must be shown to have been designed and constructed and currently functioning as integral and effective components of the property's total SWM plan; i.e. , vegetated areas of and by themselves are not a basis for fee adjustments. Fee adjustments will not be allowed for vegetated buffers established to meet specific City, state, and/or federal regulatory requirements; however, vegetated buffers established for such regulatory requirements may be omitted from the total area of the property for fee adjustment calculations. Additionally, no separate fee adjustment will be allowed for vegetated buffers required for infiltration storm water management facilities. The maximum utility fee adjustment (reduction) for a property utilizing one or more of these SWM facilities for the total area of the property will be 10% of the property's total number of ERUs, unless greater proportional savings to the utility are substantiated by the property owner. Partial fee adjustments; i.e. , less than 10%, may be allowed at the rate of 1% for each 10% of the property served effectively by the facility. E. Storm Water Flood Control Facilities An optimally designed and constructed storm water flood control facility shall control the rate and volume of storm water discharged from the property such that the post-development runoff volume and peak rate of flow from the 2-year, 24-hour storm do not exceed the pre- development runoff volume and peak rate of flow from the 2-year, 24-hour storm and do not produce erosive velocities in off-site drainage systems. In addition, an optimally designed and constructed flood control facility shall control the rate and volume of storm water discharged from the property such that the post- development off-site maximum water surface elevations for the 100-year, 24-hour storm do not exceed the pre- development off-site maximum water surface elevations for Page 8 - 42 Storm Water Management Revised 1/96 Public Works Specifications and Standards the 100-year, 24-hour storm. The maximum utility fee adjustment (reduction) for a property utilizing optimally designed and constructed storm water flood control facilities for the total area of the property will be 20% of the property's total number of ERUs, unless greater proportional savings to the utility are substantiated by the property owner. If the flood control facility also meets the storm water quality criteria for wet detention ponds, dry detention ponds, infiltration facilities, or other storm water management facilities listed in Sections 4A through 4D, the fee adjustment reduction for the flood control facility will be in addition to that granted for water quality benefits. Partial fee adjustments; i.e. , less than 20%, may be allowed where a storm water flood control facility serves less than the total area of the property, provided it is optimally designed and constructed for the partial area of the property served by the storm water flood control facility. In such case the partial adjustment (percent) , if allowed, will be equal to the ratio of the partial area served by the optimally designed and constructed storm water flood control facility to the total area of the property multiplied by 20%.

(c) Subdivision construction plans shall have incorporated into the set of plans, one overall sheet which shows the lot grading, rims and inverts of the storm drainage structures, any SWMF(wet or dry) information required, and other information as required by Section 8.19 (SWMF As-Built Drawings) and Section 11.6 (As-Built Drawings) which will be used for the as-built survey and/or certificate of completion. (d) Over excavation of storm water detention ponds, for purposes other than storm drainage, will not be allowed without the developer first obtaining a conditional use permit, for a borrow pit. If the developer wishes to mine sand, a conditional use permit must be obtained. (e) Subdivisions both residential and commercial shall not create any lots or parcels that are entirely Page 11 - 4 Site Plan & Subdivision Requirements Revised 1/96 Public Works Specifications and Standards taken up by drainage ponds, lakes or other structures to the point that the lots are unbuildable. See Section 8.8 (Open Drainage) for additional information. (f) When a construction or subdivision plan is adjacent to a future CIP road project and a right-of-way dedication is involved; a minimum five (5) foot temporary construction easement is required. If the CIP road construction plans show a different temporary construction easement width, then the same width as the CIP road plans shall be required. SECTION 11.2 Subdivision Development - Sidewalks a) Sidewalk in front of a building lot must be installed before the builder obtains a Certificate of Occupancy. b) A separate sidewalk performance bond can be posted if the Certificate of Completion, for the remaining improvements, has been signed. The request for a separate sidewalk performance bond can be made when the Certificate of Completion is submitted. The time period proposed for the bond should also be included with the request. c) The entire sidewalk improvement must be installed within the time period established for the sidewalk performance bond. SECTION 11.3 Preliminary Subdivision Review Procedures a) In some cases, a rezoning petition or use permit may be pending for a parcel at the same time that it is under preliminary subdivision review. Also, there is a certain amount of lag time from the date that City Council acts on an item, until the time that the City Clerk's Office forwards typed minutes to Planning. In order to cover these situations, the staff engineer responsible for a particular preliminary, and the developer should check with the staff engineer responsible for the Planning Commission Agenda reviews to see if there has been a recent application involving that property. If there was a recent application, the engineer could determine the status of the application or whatever other information is necessary from the Development Services Center. Site Plan & Subdivision Requirements Page 11 - 5 Public Works Specifications and Standards b) In some instances, property which is under subdivision review may have been the subject of two or more rezonings or use permits in the past. Planning will forward as many City Council cover letters as are applicable; however, the engineering staff and the developer may have some difficulty in determining what specific area of the subdivision is covered by a particular Council action. In these situations, the engineer and the developer should check Planning's files. c) The reviewing engineer should seek assistance from the Planning Department Development Services Center's planner or zoning inspector in providing the needed interpretation. SECTION 11.4 Public Drainage and Utility Easement Dedications on Final Subdivision Plats The below listed requirements shall be followed in dedicating drainage and utility easements for townhouse and detached dwelling unit subdivision plats: a) Physically show all easement dedications on the final plat. b) Specify in an easement dedication note on the final plat exactly where easements are being dedicated for each lot. c) Unless the drainage easement carries City storm water flows, the drainage easement shall be designated as "private" belonging to the appropriate homeowner. d) Appropriate environmental assessments are required for acquisition and/or dedication to the City of land for easements, for right-of-way, and for fee simple ownership by the City. SECTION 11.5 Right-of-way Dedication Requirement - Preliminary Subdivisions The purpose of this section is to establish the right-of- way requirement for those subdivisions where one or two lots are being created with a residual exceeding 15 acres. A right-of-way dedication will be required along the frontage of the lot being created, if needed in accordance with the Master Street and Highway Plan, but not along the frontage of the residue if the residue exceeds 15 acres. Page 11 - 6 Site Plan & Subdivision Requirements Revised 1/96 Public Works Specifications and Standards SECTION 11.6 As-Built Drawings A. As-Built Lot Grading The purpose of this section is to provide guidelines and step-by-step procedures for the review and subsequent approval of overall lot grading associated with new subdivisions requiring "excessive" fill and to provide by definition, a lot suitable for construction of a dwelling prior to final plat recordation. This shall cover all new subdivisions that are reviewed and approved by the Development Services Center and determined, during the design review stage, to warrant one (1) foot or more of fill to provide a minimum of one percent (1%) lot grading in accordance with the current lot grading and drainage requirements enforced by the Development Services Center. The as-built grades and information required within this section should reflect what was actually built and the as-built drawings and information should not be used as a means to check the review process. Prior to the recordation of the final plat for any newly created subdivision determined by the Development Services Center as having "excessive fill", by the established definition, the following step-by-step procedures must be completed before the Development Services Center reviews or approves the recordation of said subdivision plat. These procedures are in addition to all other procedures and requirements established under the City of Virginia Beach Subdivision Ordinance regulations pertaining to final subdivision plat recordation: 1) Procedures a. The developer initiates an "as-built" lot grading surveys to be performed by a land surveyor licensed in the Commonwealth of Virginia, upon completion of the fill requirements as dictated on the City approved design subdivision construction drawings. b. The developer, or his designated representative, submits five (5) paper copies of the "as-built" lot grading plan directly to the Development Services Center for review. Revised 1/96 Site Plan & Subdivision Requirements Page 11 - 7 Public Works Specifications and Standards c. The Development Services Center - Plan Review Staff will be assigned the "as-built" plan for review within a seven (7) to ten (10) work day time frame. Appropriately, the City Staff Engineer whom reviewed and approved the subdivision construction plans will be assigned the "as-built" plans. d. Should the reviewing engineer determine, upon completion of their review, that it is unacceptable as submitted, correspondence will be forwarded to the consultant addressing the discrepancies and corrective measures necessary. Resubmittal of the "as-built" plans will be required upon correction of the discrepancies noted. (note: Pre and Post- review conferences are recommended and endorsed by the City Engineer's Office in order to reduce the overall review time. ) e. Should the City Staff Engineer determine, upon completion of their review, acceptance and approval of the submitted "as-built" plans, the five (5) copies submitted will be approved, dated, and endorsed as such by the staff review engineer. The consultant will be notified, in writing, to obtain approved copies from the Development Services Center. The developer will be forwarded a copy of all correspondence. The approved plans will be distributed as follows: 1. Development Services Center file - 1 copy 2 . Permits and Inspection - 1 copy 3 . City of Virginia Beach Records Management - 1 copy 4. Applicant/Consultant - 2 copies f. Consultant submits reproducible (mylar) copy and original subdivision plat documents to the Department of Planning Development Services Center for processing. The above documents must be accompanied by a copy of the "as- built" approval letter as verification of lot grading approval. g. Process complete. Page 11 - 8 Site Plan & Subdivision Requirements Revised 1/96 Public Works Specifications and Standards NOTE: The building official, at his discretion, shall require the builder to submit individual "as-built" lot grading plans (prepared by a professional engineer or land surveyor) to their office prior to the issuance of the certificate of occupancy. This decision will be made at the time of the final lot grading inspection by the respective building inspector if, in their option, the incidental work performed by the builder has disrupted the minimum lot grading and/or drainage patterns established by the developer at the time of the subdivision "as-built" lot grading plan approval. 2) Requirements a. Submittal of "as-built" plans must be accompanied by a transmittal letter which includes the following information: 1) Subdivision name, lot numbers, block number and street names. 2) Must define which lots and their descriptions within the subdivision that fall into the category of review (i.e. lots with fill exceeding one (1) foot depth - total number. ) 3) Lots and their descriptions which are exempt from the "as-built" lot grading requirements are encompassed within this new subdivision (total number) . 4) Transmittal reference should include Public Works Engineering and Development Services Center file numbers. 5) Transmittal letter must indicate if developer has provided seeding of fill and graded areas to promote vegetative growth or indicate anticipated seeding schedule dates. 6) The above requirements (a - e) may be shown on the plan if preferred. b. All plan sheets are to be sealed and endorsed by professional engineer and/or land surveyor. The exact date the "as-built" information was obtained in the field must be so noted. Site Plan & Subdivision Requirements Page 11 - 9 Public Works Specifications and Standards c. A legend depicting the proposed design grades, the existing grades prior to the filling operation, and the actual "as-built" grades is to be established on all associated plan sheets. d. "Physical Lot" grades must be within two- tenths (0.2) of a foot to be an acceptable grade, however, in all cases a one percent (1%) minimum lot grade must be achieved unless approved by the review engineer. e. Surveyors obtaining the "as-built" grades must provide a minimum of four (4) grade elevations or three (3) where the design grades have been established on the approved construction plans. When two (2) as-built elevation grades are shown, it shall mean that the slope is uniform between such elevations. The intent of this "as-built" is to provide documentation to the City of Virginia Beach, that through this survey, the existing field conditions and the design approved are comparable and the developer has met the lot grading requirements in the field, as established with the approved subdivision construction plans. f. Complete sets of "as-built" plans must be submitted, no partials will be accepted. g. "As-built" plans should be the approved drawings, reproduced, with the additional "as- built" information incorporated. B.

All graphic elements shall be registered to the Virginia State Plane Coordinates System - South Zone (NAD-83) and the values expressed in International Feet (one foot equals 0. 3048 meters exactly. ) SECTION 11.7 Subdivision Performance Bonds The purpose of this section is to provide guidelines for the posting and reduction of performance sureties for subdivision developments. This shall cover all subdivision development within the City of Virginia Beach. Page 11 - 14 Site Plan & Subdivision Requirements Public Works Specifications and Standards a) Prior to the recording of an approved subdivision plat, a performance bond must be posted with the Development Services Center. The bond must cover the entire area of the plat to be recorded including street and drainage facilities within the City right-of-way and easements, all water and sewer facilities including pump stations and all street lights and traffic control devices. b) Bond amounts will be determined by estimates prepared by the developer's consulting engineer and approved by the various City agencies. The actual amount of the bond will be equal to the total of the improvements to be completed. Initial subdivision bonds will be posted for a period of two (2) years, and all renewals will be posted for a minimum of six (6) months. c) Request for bond reductions may be submitted at various stages of construction. The request must be accompanied by a revised engineer's estimate subject to approval by various City agencies. In no cases will the bond be reduced to less than twenty percent (20%) of the total improvements for the area covered by the plat. d) Upon completion of all improvements covered by the bond and approval by the various City agencies of all sections of the Certificate of Completion, the developer will be notified to post a two (2) year defect bond equal to ten percent (10%) of the total improvements for the area covered by the plat. Prior to the expiration of the two (2) year defect period, a final inspection will be made, and, if any discrepancies exist, the developer will be required to correct these before the defect bond is released. e) Satisfactory forms of surety for subdivision and defect bonds will be those acceptable to the City Attorney such as cash, letters-of-credit, or insurance bonds. f) Under certain circumstances, the Director of Public Works may approve ancillary bonds for certain improvements (e.g. sidewalks, street lights) . g) In some cases, special water system survey may be required. This survey will remain as a performance Site Plan & Subdivision Requirements Page 11 - 15 Public Works Specifications and Standards survey until connection to the City's water system is allowed. SECTION 11.8 Site Plan Performance Surety a) All site plans shall post a guarantee fees/surety/bond for which a permit is required by Section 33 of the City Code. For permits allowing open cut of roadway or where construction is determined to be of questionable durability, bonds will be held for a period of one (1) year. Otherwise, after all discrepancies have been corrected and reinspected and all highway and utilities inspection fees paid, a final release for occupancy will be granted and the bond released. Notification of release will be given the permittee and the insurance company. b) Acceptable forms of surety for site plans and subdivision plans will be those acceptable to the City Attorney such as cash, letters of credit or insurance bonds. No permits will be issued until surety is received. SECTION 11.9 Field Density Material Testing The purpose of this section is to provide guidelines for performance of field density tests in subdivision developments. Also see Chapter 4 (Geotechnical Information & Design) and Chapter 5 (Pavement Design) for additional information. This covers all field density testing in subdivision developments. a) All field density tests will be performed with a nuclear field density device and will be performed in accordance with Section 304 of the Virginia Department of Transportation Road and Bridge Specifications, (1991) . b) All subdivision developers will be responsible for contracting with a private firm at the developer's cost to perform field density test. c) Prior to scheduling field density tests, the developer will be required to call Civil Inspections of Permits and Inspections to inspect proof rolling, depth checks and the grading. Page 11 - 16 Site Plan & Subdivision Requirements Public Works Specifications and Standards d) When the field density tests are to be performed, Civil Inspections should be notified of the time. The Civil Inspector must receive a copy of the test results before the next phase of construction can begin. This copy can be a field copy. The inspector will insure by field observation that the test results are representative of the field conditions before authorization is given to proceed with construction. e) Testing should include the following information: 1. The results of the proctor test on the subgrade material. 2. The optimum moisture of the aggregate. 3 . Theoretical maximum density of the aggregate. 4. Location map showing the number and location of the test(s) performed. 5. Weather conditions during the testing. 6. The test results. 7. Evaluation of the test results and recommendations by the registered soils engineer. f) The testing frequency will be a minimum of two tests per 500 feet of roadway, with a minimum of two tests on any roadway, or as required by Civil Inspections. g) If the surface tested has been disturbed by traffic or has been adversely affected by weather, density tests will have to be repeated. h) If the test results are acceptable and the City inspector authorizes the next phase of construction, work on the next layer should begin within three (3) days. SECTION 11.10 ReQuiring Final Paving When Base Asphalt is Used The purpose of this section is to provide guidelines for determining time of placement of final paving when base asphalt is used. Site Plan & Subdivision Requirements Page 11 - 17 Public Works Specifications and Standards This applies to all subdivision developments in which base asphalt is used in the City of Virginia Beach. a) No occupancy releases will be granted until at least the base asphalt is placed. When base asphalt is used as a riding surface on occupied subdivisions, the asphalt will be placed around utility structures in such a manner as to create a safe condition for drivers, free of any sharp edges. b) The City will allow subdivisions to enter into a defect without the final asphalt in place in which intermediate or base asphalt is used if a separate bond is posted in an amount equivalent to 110% of the estimated cost of the remaining paving and related work. The estimate shall be based on unit prices contained in the City's current bituminous concrete maintenance schedule contract. c) When deferral is granted for a subdivision section, the final paving will be placed within one year from placement of the base asphalt or prior to 75% occupancy of that section, whichever occurs first. Request for time extension may be made, in writing, to the Director of Public Works. However, in no cases will a deferral be granted beyond the expiration date of the defect bond. d) When the final pavement is placed during the first year of the defect period, the defect expiration date of the project will not change. When the final pavement is placed during the second year of the defect period, the defect expiration date of the project will be extended twelve (12) months from the completion of final paving. ' e) To be considered for deferral of final paving, the drainage structures must be constructed in such a manner to allow run-off after base asphalt has been placed. This may require the use of "weep holes" on catch basins. f) Any exceptions to this policy must be approved by the Director of Public Works, Page 11 - 18 Site Plan & Subdivision Requirements Public Works Specifications and Standards SECTION 11.11 Site Plans a) Six inch (6") thick concrete dumpster pads with appropriate reinforcement shall be required on all multi-family (over 10 dwelling units) and commercial development site plans for commercial trash pickup. These concrete pads shall extend fifteen feet (15 ' ) in front of the dumpster and access to the pad shall be through the parking lot for the site. Wire mesh is not considered appropriate reinforcement. A note must be included on the plans in a conspicuous lettering that City refuse service will not be provided. See Section 11. 17 for further details. b) On site perimeter curb is required around parking lots, including all parking spaces, maneuvering spaces and drive aisles. Where parking is limited for small sites, a turn around area must be provided to ensure all vehicles will be able to exit the site without backing onto the City right- of-way. See Appendix C, drawing number C-9, for example. c) For sites with drive-up or pick-up windows such as fast food restaurants, banks, debit or credit card machines, dry cleaners, etc. , a minimum ten (10) vehicle stacking lane is required to ensure adequate on site stacking without the vehicles stacking into the right-of-way. SECTION 11.12 Request for Waiver Every effort should be made to resolve waivers of on-site and off-site improvements at the Engineering staff level, utilizing the decision making tools at hand; i.e. codes, ordinances, policies, standard procedures, and, of course, good engineering judgment. Staff is qualified to make proper decisions based on considering the aforementioned. In exceptional cases, when the engineering staff has been unable to resolve a matter, the issue will be forwarded to the Director of Planning. Prior to meeting with the requestor of the waiver, the Director should be briefed on all particulars and given staff recommendations. If through that process the matter cannot be resolved, a memo can then be prepared to the City Manager outlining all details and identifying differences, as well as staff recommendation to what the disposition should be. With that information being provided, the Manager can then make a final decision or arrange a meeting if one is necessary. Revised 1/96 Site Plan & Subdivision Requirements Page 11 - 19 Public Works Specifications and Standards SECTION 11.13 Truck Haul Any site plan involving the "Truck Haul" lanes for beach replenishment should be brought to the attention of the PW/Beach Management Office. Also, see Chapter 16 (Traffic Control) for additional information.

Such temporarily enclosed space shall not be used for human habitation. SECTION 11.20 Criteria for Installation of Residential Sewage Disposal Systems in Areas with Poorly Drained Soil and which Land Management Techniques are necessary a) For each septic tank application, an individual systematic soil evaluation will be made. This evaluation will consider site position, soil profile, seasonal water table elevation, and soil performance. When the evaluation indicates the site in question to be severely limited, soil management provisions or design and construction modifications that may overcome unfavorable site characteristics will be considered. b) On lots of less than three acres, current policy of acceptance of soils in compliance with the "Rules and Regulations" will continue. c) In high density subdivision development, with lots containing a minimum of twenty thousand (20, 000) square feet, soil used for subsurface disposal of sewage effluent shall indicate, by soil evaluation performed or reviewed by the Health Department; the minimum characteristics of a seasonal water table at one and one-half (1 2) to two and one-half (2 2) feet and moderate permeability. d) Soil management provisions or design and construction modifications to overcome unfavorable site characteristics will be considered only on sites containing a minimum of three (3) acres or more and not including swamp, or marsh land. Lot size may be increased from three acres when determined necessary by the appropriate regulatory agency. e) Soil types considered having the capability of responding to management provisions must indicate favorable permeability characteristics. Page 11 - 26 Site Plan & Subdivision Requirements Revised 1/96 Public Works Specifications and Standards f) When site drainage is considered, a land management drainage plan shall be provided. This plan must be developed, by a certified land surveyor or civil engineer, under the supervision of the appropriate local governing body official, such as the City Engineer. Upon approval of the drainage plan, the drainage must be provided under the supervision of the local Health Department. This certification will become part of the septic tank permit LHS-121. g) Storm water management for land management plans 1. Positive surface grading in the area of the dwelling and drain field must be obtained at a minimum slope of 0. 5%. a) The minimum elevation for the area of the proposed drain field shall be 6. 0 m.s. l. The Health Department may allow the area of the drainfield to be filled with native material (excavated material from the ditches) six (6) inches, maximum, in depth to achieve a minimum elevation of 6. 0 m.s. l. 2 . Side property line ditches criteria is as follows: a) Minimum bottom of ditch grade shall be 0.20%. b) The depth in the vicinity of the drain field shall be a minimum of two (2) feet; the City requirement of a maximum of 18 inches is waived for land management. 3 . Diversion ditch(es) : a) Diversion ditches are required where the adjacent property is equal to or higher than the site in elevation and may be expected to discharge storm water runoff onto the adjacent site. b) Design shall meet individual requirements. 4. Receiving Facility a) The receiving storm water facility must be adequate in capacity and depth to allow storm water runoff from the site to be conveyed to it in accordance with City policy. Revised 1/96 Site Plan & Subdivision Requirements Page 11 - 27 Public Works Specifications and Standards b) All subdivisions utilizing the Land Management Criteria (LMC) for septic tank installation in poorly drained soils are REQUIRED TO PROVIDE DOWNSTREAM DRAINAGE EASEMENTS; regardless of the adequacy of any existing system in terms of runoff computations, to such a point that the "conveyance" ditch widths to the point that it cannot be blocked by debris (generally 20' to 30 ' wide depending on the depth) . A roadside ditch which is within a public right-of-way, and part of an adequate drainage system, shall be considered to be a suitable outfall for LMC sites and no further downstream drainage easements will be required, since private water mixes with public water and the City will be responsible for keeping ditches flowing from that point downstream. However, if the system is not adequate (based on the 10 year storm) and downstream improvements must be accomplished outside of the right-of- way by the owner, appropriate easements must be obtained by the owner. c) Diversion ditches, where downstream drainage is required, or other ditches shall be provided to transport storm water from the site to the receiving body in accordance with these specifications and standards. d) Land management ditches should be designed to outfall downstream of the Storm Water Management BMP outfall, see Section 8. 18 (g) of this publication. 5) Ditches shall remain open and will not be piped or covered unless approved by the appropriate local governing agency. h) Subsurface drain fields must not be located closer than seventy (70) feet, ± 10 feet, of any drainage ditch, tile, potential drainage ditch, drainage tile, or to any property line. i) Adequate drainage easements must be provided to assure access for proper drainage maintenance. Page 11 - 28 Site Plan & Subdivision Requirements Revised 1/96 Public Works Specifications and Standards These easements shall be public and dedicated to the City of Virginia Beach. j) Political subdivisions will assure proper installation and maintenance of storm water facilities. In new subdivisions, performance bonds shall be required to insure installation of storm water facilities as a precondition to the recording of the subdivision plat; this does not apply to interior agricultural drainage. k) Adequate over-lot grading with no depression for the collection of storm water will be provided. Rough grading shall be provided prior to the installation of the septic tank and drainage fields. Appropriate local governing body, such as the City Engineer, will provide technical evaluation of the lot grading, when necessary. Final approval of residential sewage disposal systems will be contingent upon completion and approval of the lot grading, including the associated ditch work. 1) Typed on the reverse side of the LHS-121 form, will be the following statement and signed by the applicant: I understand that this soil has severe limitations for the disposal of septic effluent. With the above mentioned drainage measures, the Health Department expects reasonable serviceability, however, it may malfunction during extreme conditions. I understand and acknowledge the above, and agree to INSTALL AND MAINTAIN THE ABOVE MENTIONED DRAINAGE MEASURE. Signed: Date: m) Proper deeds will be recorded requiring that a copy of the LHS-121 be attached and become a part of any deed of conveyance. n) If any part, section, subsection, sentence, clause, or phrase is invalid; such decision shall not affect the validity of the remainder. Revised 1/96 Site Plan & Subdivision Requirements Page 11 - 29 I I Public Works Specifications and Standards o) Alternative methods of sewage disposal shall be explored. Health Department staff will assist applicants in processing applications for alternative sewage facilities. Research and development into alternative methods of approved sewage disposal will continue, and will ultimately require Health Department approval. p) Preliminary subdivision plats and land management drainage plans may be submitted to the City at the same time, however, the Health Department must first determine if the site needs land management. o) The Planning Department will require that the Health Department accept and approve a soils analysis (then the DSC approve a land management plan, if applicable) prior to approving a preliminary subdivision. Until the appropriateness of land management is decided for each subdivision, the preliminary plan will not be approved. p) Land Management Process for poorly drained soils used in the southern portion of the City for areas with poorly drained soils. The Health Department will determine whether a septic tank maybe installed by performing a "perk test" . The step by step review procedures for Land Management as follows: 1. Land owner request perk or 1. Land owner request test from Health Dept. subdivision approval from Planning 2 . Perk test performed by Health Department (subject site fails test) 3 .

In no case will directional signs be installed displaying names or locations of subdivisions. If the citizens of a subdivision desire any type of entrance sign, the established encroachment procedure shall be followed. 2 . Shopping centers and shopping malls do not justify directional signing. Generally, extensive advertising establishes the location of these sites. Furthermore, shopping centers are usually located on major arterial highways where they are very visible. 3 . Public or private transportation facilities justify directional signs in certain cases. When possible a sign shall display the appropriate symbol, e.g. bus symbol for bus station. If two similar facilities are located nearby, then a supplementary name plate should be added to distinguish between sites. The directional signs shall be used only to delineate the route to the site from nearby major arterial or interstate highways. Signs are to be installed not more than one mile from the site. 4. Off-street municipal parking facilities open to the general public may have directional signs. Signs should be used to direct motorist to municipal parking facilities in order to minimize on-street congestion. Signs shall be installed within a reasonable proximity to the parking facility as determined by Traffic Engineering. 5. Municipal services may have directional signs in certain cases. Remote municipal facilities dedicated to serve a small area of the City may have signs from the nearest arterial street only when the site is difficult to locate. The signs shall not be used for facilities where the general public does not regularly visit. As an example, remote highway storage yards, equipment storage or municipal garages do not justify signs. Precinct police stations and fire stations justify signs if they are off major arterial or located on "hard to find" sites. Page 16 - 44 Traffic Control Revised 1/96 Public Works Specifications and Standards 6. Centralized municipal facilities such as the Municipal Center may have signs within a larger radius. The Municipal Center is a central City-wide facility which generates considerable citizen traffic unfamiliar with the location of the center, e.g. , citizens needing permits, attending court, visiting social services, etc. Such directional signs will only be installed on major arterial highways. 7. Public Schools and libraries do not justify directional sign except when the facility is very remotely located. In this instance, directional signs shall be used only to direct motorist from the nearest residential collector street. Generally, with schools the users are very familiar with the location because the facility only serves a small section of the City. 8. Accredited colleges and universities including extension campuses, may have directional signs. Proof of accreditation must be submitted with any request. The directional signs shall be used only to delineate the route to the site from nearby arterial or interstate highways. 9. City, state and national parks merit directional signs in some cases. Neighborhood City parks do not justify any directional signs. City-wide or regional parks may have signs only when the site is remotely located and difficult to find. Sign placement should be limited to nearby arterial streets. 10. Other regional recreational facilities such as camping, golf, recreation areas, fishing services and theme parks may have directional signs. The signs shall in no case have individual names to delineate specific facilities. Directional signs shall be limited to a reasonable distance of the site as determined by Traffic Engineering. The recreational facilities which merit signs shall be major generators of traffic of a regional nature and not individual small sites. Revised 1/96 Traffic Control Page 16 - 45 Public Works Specifications and Standards 11. Any request for this type of guide sign shall be reviewed by the Traffic Engineering Division for conformance with this policy and the appropriateness of the proposed location of the installation. If such signing is deemed appropriate, it will be installed by Traffic Engineering personnel and the associated expense will be borne by the requesting.

SECTION 16.4 Construction - Maintenance SECTION 16.4.1 Description The purpose of this section is to set forth the basic principles and standards to be observed by all agencies, private or public, who perform work in or adjacent to a public street, to provide safe and effective work areas and to warn, control, protect and expedite vehicular and pedestrian traffic. SECTION 16.4.2 General Information a) Proper traffic control techniques shall be effectively utilized to: 1. Reduce accidents 2 . Reduce confusion for motorists 3 . Expedite traffic flow 4. Minimize injury to workmen and the public 5. Reduce damage to private and public property, Traffic Control Page 16 - 51 Public Works Specifications and Standards including damage to the construction project and construction equipment 6. Minimize the possibility of claims and litigation arising from work area accidents 7. Improve public relations b) Standardization of traffic control devices and methods of application are very important when dealing with temporary conditions. These tend to be more dangerous to the public because temporary conditions are usually unexpected. A familiar sign in a familiar configuration greatly facilitates the drivers' decision-making process. c) All traffic control devices and procedures specified in this section shall conform to the applicable provisions of the Manual on Uniform Traffic Control Devices, (MUTCD) for Streets and Highways published by the Federal Highway Administration (1988) , and Part VI of the MUTCD 1988 edition, Revision 3, dated September 3, 1993 and the VDOT Work Area Protection Manual and all revisions and special revisions published by the Virginia Department of Transportation (1995) . d) The erection of all such devices shall be accomplished according to the applicable provisions of Division VII, of the Virginia Department of Transportation Road and bridge Specifications (1994) . e) Due to the variety of conditions encountered, no one standard sequence of signs or other devices can be set up as an inflexible arrangement for all situations. An attempt has been made to eliminate unreasonable restrictions, and incorporate sufficient rules to assure adequate safety and traffic flow. f) All persons or agencies doing work in public streets or public right-of-ways are responsible for obtaining all necessary permits, coordinating the work to the satisfaction of all affected agencies and the public, and informing occupants of abutting properties of access limitations due to the work area. g) Construction or repairs of streets can create Page 16 - 52 Traffic Control Revised 1/96 Public Works Specifications and Standards hazardous conditions which may result in traffic accidents if proper precautions are not taken. Public and private agencies can be liable for such accidents through gross negligence. Proper signing, barricading and channelization on approaches and at work areas in the public street are deterrents to such accidents. h) Responsibility for the installation of adequate safety devices for the protection of the traveling public and the workmen, as well as the safeguard of the work in general shall rest with the contractor, utility company, or public department doing the work. All traffic control devices used on street construction or maintenance work shall comply to the applicable specifications of this handbook. SECTION 16.4.3 General Requirements a) Street space is at a minimum so no more space should be used for construction or maintenance work than is absolutely necessary. Through barricading and channelization, the remaining street space is to be used to carry the traffic around the work area in the best way possible under prevailing conditions. b) Traffic control devices shall be set up prior to the start of construction or maintenance operations, and shall be removed or relocated as the work is finished or work conditions change. The agency doing the work shall patrol the work site as required to ensure that all traffic control devices are in place and operating at all times. c) All traffic control signs for the work areas shall be in accordance with sections 2 .11 and 2 . 12 of this manual, pertaining to reflectivity and materials. d) At night adequate barricades with reflectorized material and lights are required to call attention to obstructions and hazards and to indicate their actual locations. e) When not in use during work hours or at night, equipment shall not be parked in such a manner as to block the motorists' view of traffic signs and signals. Revised 1/96 Traffic Control Page 16 - 53 Public Works Specifications and Standards f) The minimum width for temporary travel lanes is 10 feet; however, a 12 foot lane is advisable and should be provided wherever possible. g) Whenever traffic must be routed across the centerline, the two directions of traffic flow must be physically separated. Traffic cones can be effectively used for this purpose during daylight hours; reflectorized drums or vertical panels must be used for night-time hours. h) The peak flow of traffic in Virginia Beach occurs between the hours of 7-9 a.m. and 4-6 p.m. During these hours, construction or maintenance work which involves a moving lane of traffic will not be allowed on arterial streets except for emergency conditions or with approval from Traffic Engineering. Unless otherwise noted and under normal conditions, all work shall be done on streets within the hours of 9:00 a.m. - 4: 00 p.m. i) The agency doing the work shall provide flagmen and/or Police control when required. j) Every attempt shall be made to schedule and expedite the work to cause the least inconvenience to the traveling public. k) In situations not covered in this section, the protection of the traveling public and the protection of the workmen on the site will dictate the measures to be taken consistent with the general principles here. 1) The contractor, utility company or City department involved in the work is responsible for notifying Traffic Engineering of any work where the number of travel lanes are reduced from normal conditions or the street is required to be closed. Except in emergencies, the following notification is required: 1. Closing 1 or more travel lanes - three (3) working days prior to the scheduled work; 2 . Closing a street - ten (10) working days prior to the scheduled work. Page 16 - 54 Traffic Control Revised 1/96 Public Works Specifications and Standards 3. Where a major disruption of traffic will result from the lane or street closure fifteen (15) working days will be required. m) This lead time is necessary for planning and notifying the public of expected changes in the normal traffic conditions. n) Where a complete street closure is necessary, the agency performing the work shall obtain prior written approval by the Traffic Engineer. The contractor or agency shall be responsible for closing the street and fully signing the detour route and work zone. o) The Public Works Director or his representatives are authorized to stop any construction or maintenance activity which is not properly signed and barricaded as required by this section until such requirements are met. SECTION 16.4.4 Planning a) All work shall be planned well in advance to keep traffic obstructions, public inconvenience and lost working time to a minimum. b) Those responsible for planning should visit the job site before starting the work to consider: 1. Traffic conditions 2 . Existing traffic controls 3 . Traffic lane requirements 4. Physical features 5. Visibility restrictions 6. Access to private or business properties 7. The type, number and location of signs, barricades, lights and other traffic control devices for the job. 8. Safety of pedestrians, including the blind or other physically handicapped persons. SECTION 16.4.5 Approval Procedure For Work In City Streets a) It is necessary that both public and private agencies receive approval from Traffic Engineering before starting work that will affect traffic on City streets. Coordination can thus be achieved which can best serve the public interest. Public Revised 3/95 Traffic Control Page 16 - 55 Public Works Specifications and Standards and private agencies must notify Traffic Engineering in advance of any work activity that will effect the flow of traffic (Section 16.4. 3 . 1) . The starting date, approximate duration of the job, work area involved, and type of work to be done shall be furnished. When required by the City, a meeting in the field shall be held before the work starts. b) A traffic control plan must be provided by the contractor or agency doing any work in the street or highway, and the traffic control plan must be approved by Traffic Engineering prior to starting work. SECTION 16.4.6 Control, Warning and Guidance Devices a) All temporary traffic control devices shall be furnished, placed and maintained by the agency doing the work. Simplicity and accuracy is the keynote to safety and effectiveness. b) Traffic control devices include the following: signs, barricades, traffic cones, drums, lights, flashers, hand signaling devices and high level warning devices. 1. Signs: a) Signs, when used in construction or maintenance, serve to warn and guide the motorist of a closure or work activity before he reaches that point where the lane is closed or work is being performed. Whenever a motorist must change his path of travel due to construction, maintenance operations, or any work zone areas, signs are necessary for advance warning (see Appendix "D" for illustrations concerning required sign spacing) . Construction or maintenance warning signs shall be black/orange. b) All warning signs shall face and be visible to approaching traffic. Signs shall be clean, legible and mounted as to resist displacement. Advance warning signs shall be located on the right hand Page 16 - 56 Traffic Control Revised 1/96 Public Works Specifications and Standards side of the street (not in a travel lane) . On divided highways with a median or island width of eight (8) feet or more, supplemental advanced signs shall be placed on the left hand side of the roadway. All construction signing shall be reflectorized in accordance with specifications set forth in Section 2 . 12. Revised 1/96 Traffic Control Page 16 - 57 Public Works Specifications and Standards - 2. Position of Signs: a) Signs shall be placed in positions where they will convey their message most effectively. b) Placement must be accommodated to highway design and alignment. c) Signs shall be so placed that the driver will have adequate time for response. d) As a general rule, signs shall be located on the right hand side of the roadway. e) At no time should the bottom of a sign be lower than one foot from the top of the ground. f) Where a series of advanced warning signs are used, the warning sign nearest the work site or restriction should be placed: Urban (low speed -39 mph) 200 ' Urban (high speed +39 mph) 350 ' Rural 500 ' Expressway/Freeway 1,000 ' g) The following guideline shall be used to determine the spacing between signs used in a sign series: Urban (low speed -39 mph) 200 ' Urban (high speed +39 mph) 350 ' Rural 500 ' Expressway/Freeway 1, 000 ' Page 16 - 58 Traffic Control Revised 1/96 Public Works Specifications and Standards 3 . Channelizing Devices: a) The functions of channelizing devices are to warn and alert drivers of hazards created by construction or maintenance activities in or near the traveled way, and to guide and direct drivers safely past the hazard. Channelizing devices used herein include but are not limited to cones, vertical panels, drums, barricades, and barriers. b) Devices used for channelization should provide a smooth and gradual transition in moving traffic from one lane to another, onto a bypass or detour, or in reducing the width of the traveled way. No channelizing devices shall be placed in a moving lane of traffic without proper advance warning signs and appropriate delineation. A single cone,vertical panel, or drum shall not be placed alone in a travel lane. 4 . Channelization: a) The single most important element, within the system of traffic control devices commonly used in construction or maintenance areas (where a reduction in pavement width is involved) , is the taper that is provided for the channelization. An inadequate taper will frequently produce undesirable traffic operations with resulting congestion and possibly accidents through the area. b) The minimum desirable taper length for roadways having a posted speed of 45 m.p.h. or greater shall be computed by the formula L = S x W. The formula L = WS2 _ 60 should be used to compute taper lengths on urban, residential and other streets where the posted speeds are 40 m.p.h. or less. Under either formula, L equals the taper length in feet, W the width of offset in feet, S the posted speed or off-peak 85 percentile speed, in M.P.H. (See Table XVI-4 and Table XVI-5) Revised 1/96 Traffic Control Page 16 - 59 Public Works Specifications and Standards c) The minimum desirable length derived from appropriate formula above applies to roadway conditions of relatively flat grades and straight alignment. Adjustments may be necessary to provide adequate sight distance on the approach to the channelization. d) The real test concerning adequate length of taper is the operation of vehicles through the transition. It should be long enough so that drivers of vehicles approaching side by side have sufficient length in which to adjust their respective speeds and merge into a single lane before the end of the transition. A brief period of observing driver performances will generally provide some clear indications of the adequacy of the taper length. For example, if severe brake applications are observed, an increased taper length is indicated. e) Channelizing devices and barricades parallel to the travelway shall be spaced not more than 40 feet for speeds of 0 through 35 m.p.h. and no more than 80 feet for speeds of 36 m.p.h. or greater. Spacing on transitions, curves of 6 degrees or greater and locations determined by the Traffic Engineer shall be no more than 20 feet for speeds of 0 through 35 m.p.h. and no more than 40 feet for speeds of 36 m.p.h. or greater. f) Sometimes during maintenance operations, work at one site will extend over several days , thereby requiring that channelization be set up each morning and removed each evening. Under these circumstances the locations of the cones, drums, etc. ,should be marked at the time of the original set-up to facilitate the rapid, orderly re-setting of the devices on each succeeding day.

This column is appropriate for lane widths less than 12 feet. Traffic Control Page 16 - 61 Public Works Specifications and Standards - 5. Traffic Cone - Design: a) Traffic cones and tubular markers of various configurations are available. These shall be a minimum of 36 inches in height with a broadened base and may be made of various materials to withstand impact without damage to themselves or to vehicles. b) Orange shall be the predominant color on cones. They should be kept clean and bright for maximum target value. For night-time use they shall be reflectorized for maximum visibility. Reflectorization of tubular markers and cones shall be provided by a minimum 13- inch white band placed a maximum of 3- inches from the top, or a 6 inch band supplemented with a 4 inch band spaced a minimum of 2 inches below the 6 inch band. Reflectorized material shall have a smooth, sealed outer surface which will display the same approximate color day and night. 6. Vertical Panel - Design and Application: a) Vertical panels used as channelizing or warning devices shall be 8 to 12 inches in width and a minimum of 24 inches in height. They shall be orange and white striped and reflectorized in the same manner as barricades and mounted with the top a minimum of 36 inches above the roadway. For panels less than 3 ' in height, 4" stripes shall be used. If used for traffic in two directions, back to back panels shall be used. These devices may be for traffic separation or shoulder barricading where space is at a minimum. b) Panels with stripes which begin at the upper right side and slope downward to the lower left side are to be designated as " right " panels (VP-1R) . Panels with stripes which begin at the upper left side and slope downward to the lower Page 16 - 62 Traffic Control Revised 1/96 Public Works Specifications and Standards right side are to be designated as "left" panels (VP-1L) . 7. Drum - Design a) Plastic Drums used for traffic warning or channelization shall be approximately 36" in height and a minimum of 18" in diameter. METAL DRUMS AND SIMULATED BARREL PANELS ARE NOT PERMITTED. The markings on drums shall be horizontal, circumferential, orange and white encapsulated lens reflectorized stripes 4 to 8 inches wide, using a material that has a smooth, sealed outer surface which will display the same approximate size, shape, and color day and night. b) There shall be at least two orange and two white stripes on each drum. These stripes shall be alternating beginning at the top with orange. 8. Drum - Application: a) Plastic Drums are most commonly used to channelize or delineate traffic flow but may also be used singly or in groups to mark specific hazards. Drums are highly visible and have good target value, give the appearance of being formidable obstacles and, therefore, command the respect of drivers. When drums are placed in the roadway, appropriate advance warning signs shall be used. 9. Barricade - Design Type II barricades will not be permitted on construction projects on which the contract is awarded after July 1, 1988. On contracts awarded prior to that date, Type II barricades will be permitted until completion. For all other work, Type II barricades will not be allowed after July 1, 1988. Drums will be used in lieu of Type II barricades. a) Barricades are portable or fixed devices with one to three rails with appropriate Revised 1/96 Traffic Control Page 16 - 63 Public Works Specifications and Standards markings used to control traffic by closing, restricting, or delineating all or a portion of the right-of-way. b) Barricades consist of two types: Type II, or Type III c) Barricades with stripes which begin at the upper right side and slope downward to the lower left side are to be designated as " right " (R) barricades. Barricades with stripes which begin at the upper left and slope downward to the lower right are to be designated as "left" (L) barricades. d) Markings for barricade rails shall be alternate orange and white stripes (sloping downward at a angle of 45 degrees in the direction traffic is to past) . e) Where a barricade extends entirely across a roadway, it is desirable that the stripes slop downward in the direction toward which traffic must turn in detouring. Where both right and left turns are provided for, the chevron striping may slope downward in both directions from the center of the barricade. f) Barricade rails should be supported in a manner that will allow them to be seen by the motorist and provide a stable support not easily blown over by the wind or traffic. g) To facilitate rapid identification of channelizing devices on a job site, the name and phone number only of an agency, contractor, or supplier may be shown on the non-reflective surface of the face part of the barricade. Such identification shall be in one color and non-reflective with letters not to exceed one inch in height. Page 16 - 64 Traffic Control Revised 1/96 Public Works Specifications and Standards h) The entire area of orange and white shall be reflectorized with a material that has a smooth, sealed outer surface which will display the same approximate size, shape, and color day and night. 10. Barricade - Application a) Type II barricades are intended for use in situations where traffic is maintained through the area being constructed and / or reconstructed. They may be used singly or in groups to mark a specific hazard. b) On high speed situations where barricades may be susceptible to overturning in the wind, sandbags should be used for ballasting. Sandbags may be placed on lower parts of the frame or stays to provide the required ballast but shall not be placed on top of any striped rail. c) When a road is closed to traffic, Type III barricades shall be erected at the points of closure. They shall extend completely across a roadway and its shoulders or from curb to curb. Where access is provided through the Type III barricades,responsibility should be assigned to a person to assure proper closure at the end of each working day. d) When a road or street is legally closed, but access must still be allowed for local traffic, the Type III barricade cannot be erected completely across a roadway. Instead, an arrangement should be devised that will permit local use but effectively discourage use by through traffic. A sign with the appropriate legend concerning permissible use by local traffic shall be installed. e) Signs may be erected on barricades, particularly those of the fixed type, and they offer a most advantageous facility for this purpose. The ROAD CLOSED and DETOUR Arrow signs, and the Large Arrow warning signs, for example, can Traffic Control Page 16 - 65 Public Works Specifications and Standards effectively be mounted on or above the barricade that closes the roadway. f) For night-time use, add flashing warning lights when barricades are used.

Portable Barrier - Design and Application a) Barriers are appurtenances designed to prevent vehicular penetration from the travelway to areas behind the barrier such as to minimize damage to impacting vehicles and their occupants and to workers. They may also be used to separate two-way traffic. For nighttime use, barriers shall be supplemented by the use of standard delineation or channelization markings or devices. Page 16 - 66 Traffic Control Revised 1/96 Public Works Specifications and Standards b) Barrier vertical panels 8 inches in width and 12 inches in height shall be installed on top of the barrier. On the transition or taper sections the panels shall be installed on 48 foot centers and in the tangent sections on 96 foot centers. A type "A" flashing light shall be installed on the barrier at the breakpoint where the transition or taper ends and the barrier becomes parallel. 12. Crash Cushions a) Crash cushions are devices designed to absorb the energy of an impacting vehicle in a controlled manner such that the impact forces on the passengers are tolerable. Two types of crash cushions commonly used in construction work zones are: 1. Sand filled plastic barrels 2 . Guard Rail Energy Absorbing Terminal b) Crash cushions should be designed to meet the needs of each location, depending on the type, length and width of the hazard and this information should be included on the highway construction or traffic control plan. c) Truck Mounted Crash Cushions (TMCC) should be required on all highways and on all four or more lane roadways with posted speeds of 45 mph or greater for the following operations: 1. Pavement Marking. 2. Stationary Lane Closures. 3 . Other mobile maintenance operations occupying all or part of a lane. 4. Other situations where the Traffic Engineer feels such protection is warranted. Revised 1/96 Traffic Control Page 16 - 67 Public Works Specifications and Standards 13 . High Level Warning Device a) A high level warning device provides advance warning of a work area by being visible to the driver even when the work area is obstructed from view by vehicles or equipment. High level warning devices shall be a minimum of 9 feet high and should support at least three 18 inch high visibility orange flags. The base of all high level warning devices shall be designed or weighted to resist overturning in brisk winds. b) These devices may be used to alert motorist during the daylight hours. High level warning devices may be attached to equipment, barricades or signs, and serve as an auxiliary warning. While these devices are occasionally mounted alone on approaches to work areas, they should generally be used to supplement warning signs. The use of high level warning devices is recommended in congested areas. 14 . Lighting Devices • a) Steady-burn 1) In accordance with the modifications to the Virginia Department of Transportation's requirements for steady-burn warning lights, the City standards for traffic control devices are being likewise modified as follows: a) Barricade warning lights (type c, steady-burn) will not be required on channelizing devices. b) Steady-burn warning lights (type c) that were previously required on concrete barrier service shall be replaced with barrier vertical panels 8 inches in width and 12 inches Page 16 - 68 Traffic Control Revised 1/96 Public Works Specifications and Standards in height and shall be installed on top of the barrier. On the transition or taper sections the panels shall be installed on 48 foot centers and in the tangent sections on 96 foot centers. The panels shall be fabricated with a solid orange color made of fluorescent orange prismatic lens type sheeting. c) Due to large reduction in steady-burn lights that are to be utilized in traffic control activities, it is imperative that the reflectivity of the channelizing devices be maintained at all times. This will require regular inspection and cleaning of these items by the contractor or agency completing the work. b) Flashing 1) Yellow flashers are alerting devices to be used for advance warning and marking of unexpected hazards in or near the street. They are very effective when mounted on barricades, or on sign supports with advance warning signs. Flashers should not be used in a longitudinal display to delineate a travel path, or in a random pattern, which may confuse the motorist. They should not be used in an attempt to "guide" traffic, but only as an altering device. Where lights are needed to delineate the travel path through or around obstructions in a construction or maintenance area, the delineation shall be accomplished by use of steady burning lights. Revised 1/96 Traffic Control Page 16 - 69 Public Works Specifications and Standards 2) As used herein, barricade warning lights are portable, lens directed, enclosed lights. The color of the light emitted shall be yellow. They may be used in either a steady burn of flashing mode. 3) Barricade warning lights shall be in accordance with the requirements of ITE Standard for Flashing and Steady Burn Barricade Warning Lights. TABLE XVI - 7 Barricade Warning Lights Barricade Warning Lights Type A Type B Type C Low High Steady Intensity Intensity Burn Lens Directional Face 1 or 2 1 1 or 2 Flash Rate/Minute 55 to 75 55 to 75 Constant Flash Duration (A) 10 % 8 % Constant Minimum Effective 4 . 0 35 Intensity (B) Candelas Candelas Minimum Beam Candle c) Flashing Arrow Panels: 1) Arrow panels are signs with a matrix of lights capable of either flashing or sequential displays. Flashing arrow panels are effective day and night, for moving traffic out of a lane to the left, or to the right, and may be used for tapered lane closures and moving operations. 2) The minimum sizes for arrow panels are shown in Table XVI-8 . The flash rate should be between 25 and 40 flashes per minute. The minimum lamp "on time" should be 50 percent for the flashing arrow and 25 percent for the sequential chevron. 3) Arrow panels are required on all two or more lanes of traffic in the same direction where at least one of these lanes is closed or is being blocked, reguardless of the speed limit. Page 16 - 70 Traffic Control Revised 1/96 Public Works Specifications and Standards TABLE XVI - 8 Arrow Panel Sizes and Dimensions ARROW PANEL SIZES AND DIMENSIONS Minimum Minimum Number Legibility Type Minimum Size of Panel Lamps Distance A 24" x 48" 12 1/2 mile B 30" x 54" 13 3/4 mile C 48" x 96" 15 1 mile 3) The flashing or sequential arrow modes should NOT BE USED under the following conditions: a) When the location of the work does not require any lanes to be closed. b) When all the work is outside of the shoulder and there is no interference which requires the adjacent traveled lane to be closed. c) When the flagger is controlling traffic on a normal two-lane, two-way road. 4) Use of the arrow modes under the above conditions will lead to the loss of credibility when the arrow mode is used for lane closures and moving operations. 5) Flashing arrow panels used at night should be checked to insure that the device is properly dimmed, otherwise motorist may be temporarily blinded. Circular hoods are recommended around each of the lens to prevent side distraction at night. Revised 1/96 Traffic Control Page 16 - 71 Public Works Specifications and Standards 15. Temporary Construction Pavement Markings a. The Contractor shall have a certified Pavement Marking Technician present during marking operations. Temporary construction pavement markings shall be applied in accordance with the manufacturer's recommendations. b. During construction activities, temporary construction pavement markings shall be installed at temporary reversible crossovers, at locations shown on the plan and at hazardous locations as directed by the Traffic Engineer. c. ASPHALT CONCRETE; Temporary construction pavement markings installed on asphalt concrete pavement shall be either Type B (Class I, II, or III, Type C or Type D. d. HYDRAULIC CEMENT CONCRETE; Temporary construction pavement markings installed on hydraulic cement concrete shall be either Type B Class II, or III, Type C or Type D. Type B Class I shall not be used. e. On final roadway surfaces where traffic patterns are subject to change during construction, Type D temporary tape shall be used. f. On areas where the roadway is to be resurfaced or on areas where the pavement is to be demolished, Type B or Type C markings shall be used. g. TIME LIMITS; The following time limits are set forth for installing pavements markings on new roadways opening to traffic on resurfaced roadways and on other roadways where the pavement markings have been obscured and the roadway is open to Page 16 - 72 Traffic Control Revised 1/96 Public Works Specifications and Standards traffic. Pavement marking installation shall be completed with in the time limits herein unless otherwise directed by the Traffic Engineer. Exceptions to the below time limits will be granted only for weather restrictions. 1. Pavement marking installation on roads having traffic volumes of 10,000 ADT or more shall be completed within 24 hours after resurfacing or obscuring of the existing markings. * 2 . Pavement marking installation on roads having traffic volumes between 3, 000 and 10, 000 ADT or more shall be completed within 48 hours after resurfacing or obscuring of the existing markings. * 3 . Pavement marking installation on roads having traffic volumes of less than 3, 000 ADT shall be completed within 72 hours after resurfacing or obscuring of the existing markings. * h. If the Contractor will not have pavement markings installed within the time limits set above, the Contractor shall be required to install "Type D" temporary construction pavement marking tape within the same time limits and maintain such until the final pavement markings can be installed. The cost of installing, maintaining and removing the "Type D" temporary construction pavement marking tape shall be borne by the Contractor with no cost to the City. *See Section 16.4 . 13 for time restrictions on overall construction within 10 feet of any travel lane within the public rights-of-way.

Construction Pavement Markers a. Temporary pavement markers shall be installed with Type B, C and D construction pavement markings in work zones which will encroach upon the traveled way for a period of more than two (2) days, except that construction pavement markings placed as edge lines beside concrete barriers outside of transition areas will not require temporary pavement markers. b. Temporary pavement markers shall be installed in transition areas on twenty (20) foot centers and in all other areas on forty (40) foot centers. Temporary pavement markers shall be located in alignment with the pavement markings. Where double line pavement markings separating traffic are installed, two-way markers shall be installed on each line. The Contractor may install two one-way markers in lieu of each two-way marker at no addition cost to the City. c. Temporary pavement markers shall be installed with a hot applied bitumen adhesive except epoxy may be used on hydraulic cement concrete roadways and non-final surfaces of asphalt concrete roadways. Damage created in the pavement by removal of markers shall be repaired in kind by the Contractor at no additional cost to the City. 17 . Eradicating Pavement Markings a. Eradication shall be performed by grinding; sand blasting or a combination thereof. Grinding shall be limited to removal of material above the pavement surface except when removing thermoplastic markings Revised 1/96 Traffic Control Page 16 - 75 I I Public Works Specifications and Standards from asphalt concrete pavement, which may be removed by grinding alone. Sand blasting shall be used on both asphalt concrete and hydraulic cement concrete pavements to remove all other types of markings. Other methods may be submitted for approval by the Traffic Engineer. b. The Contractor or City agency shall contain eradication residue and have engineering controls in place, such as vacuum assisted methods, in compliance with the Occupational Safety and Health Administration's standards as detailed in 29 CFR 1926. 103 and 1910. 94 . c. When markings are removed for lane shifts, 100% of the marking shall be removed. d. Type E black construction pavement marking tape may be used to cover existing markings in. lieu of eradication methods on asphalt concrete surfaces when its use will not be required for more than 120 days. When Type E construction pavement marking tapes are specified as a pay item, the Contractor shall use this material on markings as indicated in the plans or as directed by the Traffic Engineer. Type E construction pavement marking tape shall be applied in accordance with the manufacturer ' s recommendations. Paint or liquid asphalt shall not be used. The following is the limitations of the use of Type E - Black Tape: . 1. The surface is asphalt concrete 2 . Work is at the final pavement surface 3 . Operations dictate shift in the traffic pattern 4. Traffic pattern will shift back to the original pattern within 120 days Page 16 - 76 Traffic Control Revised 1/96 Public Works Specifications and Standards 18. Hand Signalizing Devices a) A number of hand signaling devices such as STOP/SLOW paddles, lights, and red flags are used to control traffic through work zones. The sign paddle bearing the messages STOP or SLOW provides motorists with more positive guidance than flags and shall be the primary hand signaling device. Flag use shall be limited to emergency situations and at spot locations which can best be controlled by a single flagger or to supplement the STOP/SLOW paddle for greater emphasis. b) On roads posted under 45 mph, sign paddles shall be at least 18 inches wide with letters at least 6 inches high. For roads posted 45 mph or greater, 24 inch wide paddles with letters 8 inch high shall be used. A rigid handle shall be provided such that the bottom of sign paddle will be 5 ' above ground. This combination sign may be fabricated from sheet metal or other light semirigid material. The background of the STOP face shall be octagon shaped with encapsulated lens red sheeting with encapsulated lens white letters and border. The background of the SLOW face shall be diamond shaped with fluorescent orange prismatic lens sheeting with black letters and border. c) Flags when used for signaling purposes shall be a minimum of 24 by 24 inches in size, made of a good grade of red material securely fastened to a staff approximately 3 feet in length. The free edge should be weighted to insure that the flag will hang vertically, even in heavy winds. SECTION 16.4.7 naggers a) Since flaggers are responsible for human safety and make the greatest number of public contacts of all construction personnel, it is important that qualified personnel be selected. A flagger should Revised 1/96 Traffic Control Page 16 - 77 Public Works Specifications and Standards possess the following minimum qualifications: 1. Average intelligence. 2 . Good physical condition, including sight and hearing. 3 . Mental alertness. 4 . Courteous but firm manner. 5. Neat appearance. 6. Sense of responsibility for safety of public and crew. 7. Proper flagging, certification card b) The use of a hard hat and a orange vest shall be required for flaggers. For nighttime conditions similar outside garments shall be reflectorized. (Virginia Occupational Safety and Health Standards (Construction industrial) 29 CFR, part 1929, (1989 edition) . c) Flaggers are provided at work sites to stop traffic intermittently as necessitated by work progress or to maintain continuous traffic past a work site at reduced speeds to help protect the work crew. For both of these functions the flagger must, at all times, be clearly visible to approaching traffic for a distance sufficient to permit proper response by the motorist to the flagging instructions, and to permit traffic to reduce speed before entering the work site. In positioning flaggers, consideration must be given to maintaining color contrast between the work area background and the flagger's protective garments. d) Whenever practicable, the flagger should advise the motorist of the reason for the delay and the approximate period that traffic will be halted. Flaggers and operators of construction machinery or trucks should be made to understand that every reasonable effort must be made to allow the driving public the right-of-way and prevent excessive delays. e) When Flagging is required at a signalized intersection, it shall be accomplished by a City of Virginia Beach Police Officer (either on-duty or off-duty) . Page 16 - 78 Traffic Control Revised 1/96 Public Works Specifications and Standards SECTION 16.4.8 Plainer Stations a) Flaggers stations shall be located far enough in advance of the work site so that approaching traffic will have sufficient distance to reduce speed before entering the project. This distance is related to approach speed and physical conditions at the site; however 200 to 300 feet is desirable. In urban areas when speeds are low and streets closely spaced, the distance necessarily may be decreased. b) The flagger should stand either on the shoulder adjacent to the traffic being controlled or in the barricaded lane. At a "spot" obstruction a position may have to be taken on the shoulder opposite the barricaded section to operate effectively. Under no circumstances should a flagger stand in the lane being used by moving traffic. The flagger must be clearly visible to approaching traffic at all times. For this reason the flagger must stand alone, never permitting a group of workers to congregate around the flagger station. The flagger should be stationed sufficiently in advance of the work force to warn them of approaching danger, such as out-of-control vehicles. c) Flagger stations shall be adequately protected and preceded by proper advance warning signs. At night, flagger stations shall be adequately illuminated. d) At short construction and maintenance lane closures where adequate sight distance is available for the safe handling of traffic the use of one flagger may be sufficient. SECTION 16.4.9.Flagger Control a) Where the one-lane section is short enough so that each end is visible from the other end, traffic may be controlled by means of a flagger at each end of the section. One of the two should be designated as the chief flagger for purposes of coordinating movement. They should be able to communicate with each other verbally or by means of signals. These signals should not be such as to be mistaken for flagging signals. Revised 1/96 Traffic Control Page 16 - 79 Public Works Specifications and Standards - b) Where the end of a one-lane section is not visible from the other end, the flaggers may maintain contact by means of radio or field telephones. So that a flagger may know when to allow traffic to proceed into the section, the last vehicle from the opposite direction can be identified by description or license. SECTION 16.4.10 Mobile Operations a) Mobile operations are work activities that make frequent short stops, up to a 15 minute period, such as litter cleanup or pothole patching and are similar to stationary operations. Warning signs, flashing vehicle lights, flags, and/or channelizing devices should be used. b) Safety should not be compromised by using fewer devices simply because the operation will change its location frequently. Portable devices should be used. Flaggers may be used but caution must be taken so they are not exposed to unnecessary hazards. The control devices should be moved periodically to keep them near the work area. If mobile operations are in effect on a high speed travel lane, flashing arrow panels should be used. SECTION 16.4.11 Bridging of Excavation and Trenches a) Whenever necessary and possible, trenches and excavations shall be bridged to permit an unobstructed flow of traffic. Trench walls and adjacent soils shall be sufficiently stable for the use of steel plates. • b) Bridging must be secured against displacement by using adjustable cleats, angles, bolts or other devices to prevent movement by traffic. c) The trench must be adequately shored to support the bridging and traffic. d) Excavations are to be backfilled with select fill and compacted to 95% compaction in maximum one foot lifts. e) A minimum of eight inches of crush and run stone is to be placed in the excavation and a temporary asphalt patch to be placed prior to any usage by vehicular traffic Page 16 - 80 Traffic Control Revised 1/96 Public Works Specifications and Standards f) Steel plates used for bridging must extend one foot beyond the edges of the trench. Temporary paving materials (premix) shall be used to feather the edges of the plate to minimize wheel impact. SECTION 16.4.12 Pedestrian Traffic a) When the work area encroaches upon a sidewalk, walkway or crosswalk area, special consideration must be given to pedestrian safety. Since the pedestrian moves at a relatively slow rate, an effort must be made to separate the pedestrian from the work area. b) Protective barricades, fencing, handrails, and bridges, together with warning and guidance devices and signs, must be utilized so that the passageway for pedestrians, especially blind and other physically handicapped, is safe and well defined. c) Walkways in construction areas shall be maintained at least four feet in width and free from abrupt changes in grade. Obstructions within the walkway shall be illuminated during hours of darkness. Minimum vertical clearance to any obstruction within the walkway shall be seven feet. d) Where sidewalks are closed by construction, an alternate walkway shall be provided. Where it is necessary to divert pedestrians into the parking lane of a street, approved barricading or delineation shall be provided to separate the pedestrian walkway from the adjacent traffic lane. At no time shall pedestrians be diverted into a portion of the street used for vehicular traffic. Whenever a sidewalk must be closed due to construction and / or maintenance activities, the agency doing the work must obtain a permit from the division of Highways, and Traffic Engineering of the City of Virginia Beach. e) At locations where alternate walkways cannot be provided, appropriate signs and barricades must be installed at the limits of the work area and in advance of the closure at the nearest crosswalk or intersection to divert pedestrians across the street. Revised 1/96 Traffic Control Page 16 - 81 I it Public Works Specifications and Standards SECTION 16.4.13 General Traffic Control And Time Restrictions On Construction Near Travel Lanes Traffic Control Notes shall be included on all projects. Traffic Engineering will determine which notes shall apply. See Appendix E, Table E-10, Page E-59. On all construction projects, any work within any travel lane and/or next to and within ten (10) feet of any travel lane, within the City right-of-way, must be completed with the finished paving, removal of obstructions and traffic control, and completion of all work, in accordance with the following restrictive time criteria: I. For total work area within ten (10 ' ) feet of a travel lane in the City right-of-way as (including all construction and disturbed areas and staging areas) within the City right-of- way of less than 100 feet in length and less than 2 , 000 square feet in area (as measured within the right-of-way) : 25 mph speed & less than 500 vpd - 14 calendar days* 25 mph speed & less than 2000 vpd - 10 calendar days* 25 mph speed & less than 500 vpd - 10 calendar days* 35 mph speed & more than 500 vpd - 6 calendar days* More than 35 mph speed - 6 calendar days* II. For total work areas within ten (10 ') feet of travel lane in the City right-of-way between 100 feet in length and 1, 000 feet in length and between 2 , 000 and 20, 000 square feet in area: 25 mph speed & less than 500 vpd - 56 calendar days* 25 mph speed & less than 2, 000 vpd - 40 calendar days* 35 mph speed & less than 500 vpd - 24 calendar days* 35 mph speed & more than 500 vpd - 24 calendar days* More than 35 mph speed - 24 calendar days* III. Major projects with work areas within ten (10 ' ) feet of a travel lane in the City right-of-way above 1, 000 feet in length and above 20, 000 square feet of disturbed area, the professional engineer designing the plan shall make a recommendation and show on the plans the time restriction(s) appropriate to conditions. The City will review and approve these time restrictions if appropriate. IV. The above time restrictions may be decreased at the discretion of the City, during permit or plan review, if other conditions dictate, such as narrowness of pavement, curves, congestion, etc. If the above cannot be met, then an interim asphalt patch or pavement may be used for an additional seven calendar days at which time, it shall be removed prior to final paving. Page 16 - 82 Traffic Control Revised 1/96 Public Works Specifications and Standards Temporary and/or permanent pavement markings must be installed within the number of calendar days specified in Section 16.4. 6 (15) and (16) and prior to opening to traffic. The time restrictions specified in Section 16.4. 6 (15) and (16) for temporary and/or permanent pavement marking are in addition to the time restrictions in I and II above. This applies even if lane closure is approved and this applies to all City work and City contracts as well as to private development work and any utility (City and private) work. *As measured from the time when any land disturbance, paving, milling, digging, pavement cutting, installation of traffic control, incidental related work, or any other appropriate disturbance or public inconvenience commences. Traffic counts may be estimated by using standard accepted computational methods if no traffic counts exists. If a contractual relationship exists between the City and the contractor, then the contract, along with the plans specifications, shall control. The City inspector or City project manager may specify or authorize extensions on these time restrictions only for appropriate justification, and only as long as work by the contractor or utility progresses in a resonable workmanlike manner and not abandoned for more than the aforementioned time limits. Appropriate justification to specify or authorize extensions on these time restrictions for projects may include, but are not limited to: - The large extent of the work such as travel lane reconstruction/addition more than 1, 000 feet long. - Unknown utilities or extensive utility relocation required. This is an applicable justification only if prior location dig-ups have been performed by the design consultant during design. - Unknown poor subgrade that requires drying out. This is appropriate as justification only if the design consultant has obtained soils tests previously during design. - Weather. - No road/travel lanes were previously existing at this location and there is no inconvenience to the public. If appropriate utility location dig-ups and soil borings/tests have not been performed, then utility and subgrade (soils) problems and delays are not appropriate justification to extend the time frames required in this section. Revised 1/96 Traffic Control Page 16 - 83 Public Works Specifications and Standards Larger construction and work projects in the City right-of-way, although not necessarily under the aforementioned time limits to finish all work in the City right-of-way, shall not cease and abandon the work for more than the aforementioned time limits. In addition, these projects shall continue the overall work in a reasonable, workmanlike manner. The design consultant shall also show appropriate time restrictions on the plans. If any construction or work project ceases the work and/or abandons the work in the City right-of-way for more than the time allowed, then the City, at its discretion, may file on the bond posted with the City, immediately shut down the entire project, including work outside the right-of-way, and thereby proceed to take any other appropriate action as necessary to complete the work within the City right-of-way. Abandonment shall mean the ceasing of work, ceasing of workmanlike progress in a reasonable manner, unreasonably removing necessary machinery, equipment, supplies, personnel, etc. , off the work area or other actions that appropriately indicate to the City that work is abandoned. SECTION 16.4.14 General Street Closure a) No more than two (2) complete road closures are permitted at any given time within any residential subdivision so as not to excessively inconvenience residents and to impede emergency access. b) The contractor shall submit at the preconstruction meeting his schedule of construction sequence and a list of all proposed street closures and dates of closures that may be in effect during construction. c) The contractor shall submit to Traffic Engineering, a traffic control plan for each separate street closure within five (5) working days prior to the starting of each separate street closure. The contractor shall not close a street to through traffic unless there is an approved traffic control plan on site for that particular street. d) Advanced warning signs for a street closure shall be provided in each direction affecting traffic flow. Signs shall be mounted on 4" X 4" wooden post, and shall be 7 feet from the bottom of the sign to the top of the ground. At a minimum, these signs shall include: 1. "ROAD WORK AHEAD" 48" X 48" (W20-1) 2 . "DETOUR AHEAD" 48" X 48" (W20-2) 3 . "DETOUR ROUTE MARKER" 30" ,X 24" (M4-9) 4. "END DETOUR" 24" X 18" (M4-8a) Page 16 - 84 Traffic Control Revised 1/96 Public Works Specifications and Standards _ e) All traffic control signs shall be equipped with flashing warning lights and orange warning flags 24" x 24" . SECTION 16.4.15 Summary a) The standards presented in this section are the minimum required. Additional signs, cones, barricades, and warning devices may be used but at no time will less than what is specified here be acceptable. Since public safety is involved, a high degree of conformity to the presented standards is necessary. b) In all cases, the guidelines in this section and the traffic control plan should conform to, or be of higher standards than, the Manual in Uniform Traffic Control Devices, (MUTCD) . Adequate protection of the traveling public, workers, and pedestrians will dictate the measure to be taken, consistent with the information presented herein and in the MUTCD. c) This section was designed and written to be used with, not to replace, the MUTCD, which has the finial authority over this section. It should be useful to anyone involved with planning, designing, installing, maintaining, and inspecting traffic control. d) Other traffic control devices or applications may be used, but only with the approval of the Traffic Engineer for the City of Virginia Beach. SECTION 16.5 Sequence of Construction All roadway plans designed for (or by) the City of Virginia Beach shall include a sequence of construction section for the project. In this section, the designer shall address each phase and stage of construction on a step by step basis. A written narrative of each phase and stage shall be included as part of the plans. The construction project shall be depicted on a 1" = 50 ' maximum scale map for each stage. Phases and areas of construction shall be identified by shading, cross hatching, or some other symbol. Each phase/stage of construction shall include a maintenance of traffic plan complete with the following: a) Temporary striping with temporary raised pavement markers included in the transition and merge tapers. Revised 1/96 Traffic Control Page 16 - 85 Public Works Specifications and Standards b) The locations and identifications of all channelizing devices shall be shown. c) All temporary traffic control and warning signs for construction shall be located and identified on the plan. Provide MUTCD type and size. d) All pertinent traffic control notes (see Section 16. 3 .13) shall be included as part of the traffic maintenance plans. e) Dimensions for merge tapers, transition lengths, and sign spacings shall be depicted on the plans. f) Temporary street lighting locations (if warranted by construction sequencing, traffic volumes, and/or roadway geometries) shall be depicted on the plans. g) Any temporary signalization installations or modifications of existing signals must be addressed on the maintenance of traffic plans. A separate, more detailed sheet may be necessary for this work. h) Any street closures and detours necessary for construction of the roadway project shall be included with the sequence of construction plans. Any street closures included in the plan will be approved in advance by the City Traffic Engineer. The designer must provide written justification for the street closure. i) If warranted, concrete barrier service may be required on a roadway project. If required, this barrier service shall be depicted on the sequence of construction plans with all openings and end treatments located and identified. All geometries of channelizing device placements, temporary striping layouts, and construction signing sequences shall be in accordance with the current edition of the Manual on Uniform Traffic Control Devices or the Virginia Work Area Protection Manual. SECTION 16.6 Construction Haul Routes SECTION 16.6.1 General The intent and purpose of this section is to provide specific information and direction needed to prepare CONSTRUCTION - HAUL ROUTE plans and specifications for roadway, utility,and other development projects in accordance with the requirements of the City of Virginia Beach. The guidelines in the section are a supplement to current edition of the Virginia Department of Transportation, Road and Bridge Specifications. Page 16 - 86 Traffic Control Revised 1/96 Public Works Specifications and Standards SECTION 16.6.2 Requirements Haul routes shall be established between the project area and material source(s) that will minimize disturbance to the community and shall in all cases utilize arterial and collector roadways, and not utilize residential streets in compliance with VDOT-Section 104. 04-(k) . However, if a project is located within a residential area, special approval must be granted by Traffic Engineering. Haul route plans shall include the following information for review: a) A map outlining the direction of hauling to and from the work site. ( Map must be an appropriate City map at a scale of 1" = 3200' ) . b) A listing of all bridges within the City limits that will be traveled upon during the hauling procedure. c) Haul route entrance points on the project site and material site(s) to be utilized. d) A traffic control plan showing placement of "TRUCKS ENTERING HIGHWAY" signs and other advance warning signs to be installed on the approaches of the access point. All traffic control signs and devices shall conform to the Manual on Uniform Traffic Control Devices for Streets and Highway. e) If flagmen are needed to warn or to direct traffic at established access points entrances, a traffic control plan shall be included showing proper placement and selection of advance warning signs. f) All traffic control signs shall be removed or covered when haul route is not in affect. g) Include traffic control notes on plans and in the specifications. SECTION 16.6.3 Time Restrictions Traffic Engineering will determine the times of day trucks are hauling on the street or highway. Traffic Engineering reserves the right to restrict the hours of which time trucks are hauling on the street or highway. This may be done due to traffic volumes during peak hours or special events. Revised 1/96 Traffic Control Page' 16 - 87 Public Works Specifications and Standards SECTION 16.6.4 Approval All proposed HAUL ROUTES shall be reviewed and approved by Traffic Engineering. Traffic Engineering shall review the haul route plan within five (5) working days after receipt. Haul Route activity shall not begin until an approved Haul Route plan has been returned to the contractor, and all traffic control devices have been installed according to the approved traffic control plan.

Further development of this parcel will have to conform to all City of Virginia Beach Development Ordinances. Appropriate environmental assessments are required for acquisition and/or dedication to the City of land for easements, for right-of-way, and for fee simple ownership by the City. Page E - 20 Appendix E Revised 1/96 Public Works Specifications and Standards City policy requires the subdivider to install additional right of way improvements along to conform to current standards. However, because of existing substandard improvements in the area, the location of the site, and the minimal impact of the lot subdivision on the existing transportation and drainage facilities, it is recommended that the requirement be waived. City policy requires the subdivider to dedicate to the City of Virginia Beach that portion of the proposed right of way for , which lies adjacent to or within the boundary of the subdivision, and to deposit in the subject road project account the cost of design and construction of a standard city street for the entire length of the roadway through or adjacent to the proposed development. This cost is presently estimated at per linear foot and the actual escrow cost will be determined at the time the escrow is posted. An erosion, sediment control and tree protection plan with a surety bond in the appropriate amount will be required prior to the commencement of any land disturbing activity. A one (1) foot no ingress/egress easement is required along for parcel(s) City policy for a foot right of way requires the developer to construct pavement widening to set the face of curb feet from the centerline of the ultimate right of way and include curb and gutter, sidewalk, and drainage improvements for A City drainage and impoundment easement must be platted over the entire lake system and the following note shown on the plat: "Drainage and impoundment easement is hereby dedicated to the City of Virginia Beach for all of the following, but not limited to, conveyance, collection, storage, drainage, impoundment, treatment and other related uses of surface water and/or ground water. No alterations whatsoever of the lake and its bank side slopes within the limits of the drainage and impoundment easement is permitted without the approval of the Virginia Beach Department of Public Works. City maintenance shall be limited to that as described above. " A twenty (20) foot maintenance easement as measured from the top of bank shall be platted and dedicated to the City. Revised 1/96 Appendix E Page E - 21 Public Works Specifications and Standards Portions of this subdivision may be affected by the Floodplain Ordinance. This subdivision will adversely affected by the Floodplain Ordinance, and, therefore, it will result in major changes to this preliminary layout with the potential for loss of lots. Because of excessive fill required in conjunction with this development, "As-Built" lot grading plans must be submitted reviewed and approved by the City Engineer's Office prior to final subdivision plat recordation. On-site retention will required in conjunction with this development. A hydrology study will be necessary to establish the on-site and downstream drainage requirements and easements. City policy requires the subdivider to install additional right of way improvements along the frontage of . However, these improvements may be deferred. A recordable agreement is to be executed prior to the approval of the final plat which states that the owner agrees to pay the full cost of improvements along if the city has a project in the future. He also is to agree to dedicate whatever additional right of way may be needed at the time the improvements are to be installed. If the city has no project within ten years of the recordation date, the agreement will become null and void. All roadways 48 feet face to face or larger must be designed to VDOT TC-4 standards with a maximum super elevation of e=0. 03 foot per foot. No retention system in this residential development is to rise above the 100-year rise shown on the Federal Emergency Management Agency flood maps adopted by the city, unless existing ground on all lots is above the ultimate rise in the retention system. In accordance with the City's Master Street and Highway Plan and the City's Bikeway Plan, which calls for an• ultimate foot right of way for a dedication of feet will be required along the frontage of this parcel. The following note must be placed on the final plat: "Further development of these lots including any filling Page E - 22 Appendix E Revised 1/96 Public Works Specifications and Standards or physical alterations of the lots may require additional permits from the City of Virginia Beach or other governmental agencies. " Section 4.4 (k) . This plat shall show the approximate high waterlines, bulkheads, pier lines if officially established top of bank and toe of slope, and where such lines are intersected by lot or block lines, measurements locating such intersection shall be given along lot or block lines. Section 6.2 (p) . A foot right of way dedication is required along to upgrade this roadway to an acceptable minimum foot right of way. A foot width right of way dedication is required along in accordance with the city project/ preliminary alignment on file in the City Engineer's Office. A foot right of way dedication is required along in conjunction with the development. The existing perimeter ditch(es) adjacent to this subdivision is/are to be piped with this development. Should turn lanes be required by Traffic Engineering, additional right of way dedication will be required. The requirement for a traffic analysis should be/will be addressed by Traffic Engineering for this development. Traffic Engineering has been notified. Downstream drainage easements will be required since the down stream system is manmade. A note must be placed on the final plat stating that the property owner will maintain the on-site gravel driveway sufficient to support emergency vehicles at all times. Right of way improvements (i.e. , pavement widening and gravel shoulder) are to be constructed along in conjunction with this development. The proposed pavement widening is to be measured 12 feet from the centerline of the existing paved roadway and, in addition, include a four (4) food wide by six (6) inch deep gravel shoulder with relocated drainage ditches/swales as necessary. Construction plans are to incorporate the above requirement. Revised 1/96 Appendix E Page E - 23 Public Works Specifications and Standards A four (4) foot wide by six (6) inch deep gravel shoulder extending 30 feet on the approach side of all proposed driveways is required with this development. If necessary, existing drainage facilities associated with the gravel shoulder installation may be required to be relocated. Townhouse and condominium development requires the installation of concrete swales or combination swale/pipe systems within the rear lot and side lot drainage easements. All concrete swales and combination swale/pipe systems must be constructed with a minimum 0.5% slope. Easements along rear and side lot property lines must be dedicated as "private drainage, pedestrian, and/or utility easements" and a minimum five (5) foot width is required on each side of the property line. These easements shall be dedicated by a recorded master deed of easement. In accordance with the Department of Public Works policy for townhouse and condominium development, all utilities, both private and public located within the drainage, pedestrian, and/or utility easement, must be installed in the established utility location area. The following note must be placed on the final plat: "No encroachments (i.e. , permanent or temporary above grade structures) will be allowed within the drainage, pedestrian, and/or utility easements unless approved by the Department of Public Works. This subdivision will be adversely affected by the Chesapeake Bay Preservation Act (CBPA) Ordinance. The features and requirements of the CBPA must be shown on the construction plans in conjunction with this development and, therefore, may result in major changes to this preliminary layout with the potential for loss of lots. A Declaration of Covenants for Environmental Permits for Subdivisions must be executed and recorded prior to final plat recordation. The city makes no guarantees as to whether any of these newly created lots are buildable or not since the owner has not yet obtained all necessary environmental permits, including the U.S. Army Corps of Engineers. Page E - 24 Appendix E Revised 1/96 Public Works Specifications and Standards City policy requires the subdivider to submit for review and approval one master utility and landscape layout plan in conjunction with this development which shows all major utilities (water, sewer, power, gas, street lights, telephone, television) landscape plan, storm drainage (including Best Management Practices) , and standard roadway section including curb, gutter, and sidewalk. This plan must show all utilities and shall be used in the determination of the appropriate right of way width, therefore, this subdivision may result in major changes to the preliminary layout with the potential for loss of lots due to the wider right of way requirements.

This document should be adopted as the single official manual to ensure proper selection, design, and maintenance criteria for acceptable types of SWMFs to be used within the City. Because maintenance of SWMFs is critical to their effectiveness in reducing pollutant loadings from stormwater, the revised design guidelines should also specify types of acceptable types of SWMFs to be used within the City. Because maintenance of SWMFs is critical to their effectiveness in reducing pollutant loadings from stormwater, the revised design guidelines should also specify types of acceptable SWMFs as well as their design criteria in order to ensure that only "maintenance-friendly" SWMFs are installed in the City. In addition, the goals of the NPDES stormwater management program for Virginia Beach should be addressed in the revised manual by only allowing SWMFs which are effective in reducing loads of most or all of the 12 pollutants specified in the NPDES regulations. In addition to the proposed single SWMF document, the Environmental Coordination Report (April 24, 1992) to James K. Spore, City Manager, recommended that the City compile all of the water quality/stormwater management ordinances into a single document (each remaining as a separate ordinance) , edited to ensure procedural and technical consistency. This report also recommended the development of a concise introductory chapter that explains the City's approach to surface water quality management and the role each ordinance plays in that approach. The committee report continued to say that because each ordinance was developed separately, there are inconsistencies in the ordinances in such areas as definitions, technical criteria, and administrative processes. However, considered collectively, the ordinances form the basis for a coordinated approach to surface water quality management associated with development activities. Once edited for procedural and technical consistency, this compilation of water quality/stormwater Revised 1/96 Storm Water Management Guidance Manual Page F - 3 Public Works Specifications and Standards Typical components of the management hierarchy are listed below in order of consideration: (1) Credit for Existing Programs and Facilities: The starting point for the management hierarchy is the documentation of the existing municipal programs and facilities which already achieve reductions in stormwater pollution discharges. Examples of existing structural Stormwater Management Facilities (SWMFs) within the City include: existing roadway maintenance programs, spill control programs, and other stormwater management programs. The reduction in stormwater pollution discharges achieved by existing municipal programs and drainage facilities has been estimated to determine benefits from the existing operations. (2) Enhancements to Existing Nonstructural Programs: The City has identified enhancements to existing nonstructural control programs which can achieve additional reductions in storm water pollution discharges. As an example, the Adopt-a-Waterway program will focus on wet detention basins and canals, lakes and ponds that function as SWMFs. (3) New Nonstructural Controls: The City has identified new nonstructural control programs which can achieve additional reductions in stormwater pollution discharges. Examples include public education programs for management of used oil and pesticide applications. (4) Structural Controls for Future Development: The City of Virginia Beach requires the employment of structural SWMFs (e.g. , stormwater retention and detention ponds) for new development to reduce post-development discharges of storm water pollution. Performance standards for storm water pollution controls are typically related to predevelopment stormwater discharges. Structural SWMFs for new urban development are Revised 1/96 Storm Water Management Guidance Manual Page F - 5 Public Works Specifications and Standards is located far enough downstream to manage a fairly large service area, but not so far downstream that it impacts major stream channels. The front-end costs for constructing regional SWMFs are typically assumed by the local government which administers the regional facilities plan. Capital costs for the facilities are then recovered from upstream developers on a "pro-rata" basis as development occurs. Individual regional SWMFs are usually phased in as future development occurs rather than having all regional facilities constructed at one time. Maintenance responsibility for regional structural SWMFs is generally assumed by the local government. The other approach to a comprehensive stormwater management program is the use of onsite SWMFs. This approach involves requiring the construction of one or more stormwater management facilities (e.g. , detention basins, infiltration devices) , within the development site boundaries for future land development projects to achieve specified performance standards for storm water management. An onsite SWMF basin typically has a maximum drainage area on the order of 20 to 30 acres. This means that about 10 times more onsite SWMF retention or detention facilities are required to control the same service area as a single regional detention facility. Unlike the regional approach, all requirements for implementing onsite retention or detention facilities reside with the respective land developers. The local government is responsible for reviewing each structural SWMF design to ensure conformance with specified design criteria, for inspecting the constructed SWMF to ensure conformance with the design, and for ensuring that a maintenance plan is implemented for the facility. Revised 1/96 Storm Water Management Guidance Manual Page F - 7 Public Works Specifications and Standards 2 . 0 EXISTING ORDINANCES This section summarizes the existing ordinances (and the proposed Owl Creek Watershed Protection Program) which require storm water management planning for new development and redevelopment projects. These ordinances and The Comprehensive Plan reference the SWMF manuals that are summarized in Section 3 . 0. 2 . 1 SITE PLAN ORDINANCE The Site Plan Ordinance (City Code, Appendix C) ensures that minimum standards and conformity are met by all new development and redevelopment projects in the City of Virginia Beach. This ordinance requires submission and approval of a site plan before commencement of construction. The Site Plan Ordinance requires that adequate drainage be provided with each development and the corresponding Stormwater Management Ordinance (SWMO) requires submission of a stormwater management plan (including water quality aspects) with all site plans. Stormwater management described on all site plans must be in accordance with Department of Public Works design standards. In addition to a plan to manage post-development stormwater, all site plans must include provisions and a schedule for the adequate control of erosion and sedimentation during construction in accordance with the Erosion and Sediment Control Code (City Code sections 30-56 through 30-78) . In addition, open space on development parcels must be provided according to lot size and zoning. City landscaping standards must be met by all site plans and an approved Landscaping Plan is required for both new development and for redevelopment. Planting of trees over underground stormwater management controls is prohibited. Revised 1/96 Storm Water Management Guidance Manual Page F - 9 Public Works Specifications and Standards The key to the effectiveness of this ordinance is the requirement of submission of a stormwater management plan for most site plans submitted to the City for review. As discussed above, site plans are required for all new development as well as for alteration or improvement of existing development. The only development activities exempt from the Stormwater Management Ordinance requirement is disturbance of less than one acre or a single-family residential structure or additions not part of a subdivision. See conditions for exemption in the SWMO and in Chapter 8, including the requirement for downstream easements. In addition, variances to the stormwater management plan requirement may be granted if: the rate stormwater runoff is unchanged, the redevelopment action will not have adverse impacts on a wetland, upstream or downstream watercourse, or water body, or will not contribute to degradation of water quality. The stormwater management plan must meet performance standards for stormwater quantity such that runoff after development is approximately equal to runoff before development unless discharged to an off-site stormwater management facility. Performance standards for water quality specify the "protect[tion] or restor[ation] of the quality of ground and surface waters" and "protect[ion of] the beneficial functioning of wetlands as areas for the natural storage of surface waters and the chemical reduction and assimilation of pollutants" . Design criteria to be used in the development of a stormwater management plan for areas of new development or redevelopment include the following: • Runoff routed through systems to allow suspended solids to settle and remove pollutants. • Runoff shall be detained and retained before it enters any natural watercourse to preserve natural hydrodynamics of watercourses and to prevent siltation or other pollution. Detention and retention ponds shall be used to manage the increased and accelerated runoff from development. Revised 1/96 Storm Water Management Guidance Manual Page F - 11 Public Works Specifications and Standards Chesapeake Bay for the express purpose of protecting water quality in the Bay. This ordinance was adopted in order to implement the requirements of the Chesapeake Bay Preservation Act (CBPA) of the Code of Virginia. Virginia Beach was designated "provisionally consistent" with the CBPA and must implement specified changes to the Chesapeake Bay Preservation Area Ordinance in order to obtain a "consistent" status. These changes will be implemented by the Department of Planning. Additionally, The Comprehensive Plan will be amended by the City as appropriate in order to comply with the Chesapeake Bay Preservation Act and associated regulations. In addition to the stormwater management plan requirements of the Stormwater Management Ordinance, development in Chesapeake Bay Preservation Areas must also meet the following performance standards: • Postdevelopment nonpoint source pollution runoff load must not exceed the predevelopment load for areas of new development, a 10% reduction of pollution load for areas of intense development or redevelopment, and a 40% reduction in nonpoint source pollution from agricultural areas. • Development disturbing more than 2,500 sq ft shall comply with erosion and sediment control requirements. • ' A reserve sewage disposal drainfield site with a capacity of at least equal to that of the primary sewage disposal drainfield site shall be provided, unless, in the judgement of the Virginia Beach Health District, the area of such lot is insufficient to accommodate such reserve drainfield site. The use of buffer zones and structural controls to meet the performance standard is encouraged. Long-term maintenance of structural controls must be addressed as part of the proposed plan. In addition, a water quality impact assessment is required for any development or redevelopment within a resource Revised 1/96 Storm Water Management Guidance Manual Page F - 13 Public Works Specifications and Standards • Postdevelopment runoff quantity must not exceed predevelopment conditions unless runoff is discharged to a regional SWMF facility. • The quality of surface waters and groundwater shall be protected and enhanced where practicable. • A reserve sewage disposal drainfield site with a capacity of at least equal to that of the primary sewage disposal drainfield site shall be provided, unless, in the judgement of the Virginia Beach Health District, the area of such lot is insufficient to accommodate such reserve drainfield site. Design criteria to be used to meet the performance standards include the retention or detention of runoff by stormwater management ponds to remove pollutants to the maximum extent practicable before it enters any watercourse. A plan for the maintenance of best management practice facilities must be included. The City reviews all site plans for development or redevelopment for conformance with the provisions of the Southern Watersheds Management Ordinance. Inspection during construction is provided by the Departments of Public Works and Agriculture. Violations of provisions of the Southern Watersheds Management Ordinance may be enjoined and civil penalties or civil charges up to $2, 000 may be imposed. 2 . 5 EROSION AND SEDIMENT CONTROL CODE The City's erosion and sediment control requirements (City Code sections 30-56 through 78) are intended to manage stormwater during construction activities to minimize water quality impacts. These requirements implement the State's Erosion and Sediment Control Law and the State Erosion Control Regulations promulgated by the Virginia Soil and Water Conservation Board (Code of Virginia, Section 10.1-562) . Revised 1/96 Storm Water Management Guidance Manual Page F - 15 Public Works Specifications and Standards 2 . 6 OWL CREEK WATERSHED PROTECTION PROGRAM A program for the protection of water quality including an ordinance to impose additional restrictions on development or redevelopment activities in areas draining to the Atlantic Ocean via Owl Creek is currently being developed by the City. The Owl Creek watershed is the only area of the City where development restrictions tailored to the special needs of the watershed presently are not required. Revised 1/96 Storm Water Management Guidance Manual Page F - 17 Public Works Specifications and Standards regional objectives and requirements. Its purpose is to provide guidance to persons preparing stormwater management plans and persons designing or operating drainage systems. The manual is designed to address the needs of a broad range of users and has been adopted as the City's SWMF manual. Revised 1/96 Storm Water Management Guidance Manual Page F - 19 Public Works Specifications and Standards 3.2 ADDITIONAL DESIGN GUIDELINES Section 4. 0 of this manual presents standards and specifications for selected SWMFs including wet retention basins, extended dry detention basins and infiltration basins. Revised 1/96 Storm Water Management Guidance Manual Page F - 21 Public Works Specifications and Standards retention basin to a given area will depend on topography, soil conditions and adequate site size. Where possible, wet retention basins should conform to the existing topography with a minimal amount of excavation required. Soils should not be highly permeable so that a permanent pool can remain at its design level. Consideration should also be given to the depth to bedrock, location of existing underground utilities, and low marshy areas where wetland permits may be required. Revised 1/96 Storm Water Management Guidance Manual Page F - 23 Public Works Specifications and Standards 4 . 1. 3 PLANNING CONSIDERATIONS Wet retention basins provide water quality and erosion/flooding control benefits. The water quality goals for a watershed must be considered in planning for onsite and regional detention basins. The goals may be to limit or reduce the pollutant loading from runoff to the receiving streams, or a more specific goal may arise to reduce by a given amount the load into an environmentally sensitive area or downstream lakes. The pollutant removal efficiency of a wet detention basin depends primarily on the size and design of the permanent pool. The pollutant removal mechanisms include sedimentation and biological uptake. Erosion and flooding control goals and/or policies must also be considered for multipur-pose basins. Outlet structures can be designed to control future development peak discharge rates so that the release is equal to or less than the existing development peak rates. Wet retention basins are usually attractive, particularly if there is extensive wetland vegetation around the perimeter of the permanent pool. Wet retention basins are considered as property value amenities in many areas. Wet retention basins also offer the advantage that sediment and debris accumulate within the permanent pool. Since these accumulations are out-of-sight and well below the basin outlet, wet retention basins tend to require less frequent cleanouts to maintain an attractive appearance and to prevent outlet clogging. If the drainage area is too small, storm runoff and dry weather inflows into the wet retention basin may be too small to maintain a permanent pool during "dry" seasons. While excessive drawdown of the permanent pool does not pose a nonpoint pollution control problem, it will cause aesthetic problems.

"VR" is the mean annual runoff volume for the drainage area. "Z" is the mean depth of the permanent pool (VB/As) . Revised 1/96 Storm Water Management Guidance Manual Page F - 27 Public Works Specifications and Standards For regional SWMFs which typically drain a few hundred acres, minimum surface areas can be set at levels which facilitate maintenance activities. Assuming drainage areas (Aw) up to 300 acres, and a 3-acre minimum surface area, an As/Aw ratio of 1% will result with average TSS removal rates on the order of 90 to 95 percent for residential watersheds. Revised 1/96 Storm Water Management Guidance Manual Page F - 29 Public Works Specifications and Standards For nonresidential watersheds with relatively high levels• of imperviousness, As/Aw ratios in excess of about 3% are desirable to achieve high levels of sedimentation. Peak Flow Control Additional storage may be provided above the water quality pool in order to meet flow reduction goals for erosion and flood control. This storage may be determined based on the design storms as described in the flood control criteria section of the Public Works Design Guide (March 1990) and in the Stormwater Management Ordinance. Minimum Drainage Area For onsite SWMFs, the minimum drainage area should permit sufficient flow to prevent severe drawdown, with its associated aesthetic problems, during dry periods. Drainage area is also a factor in the sedimentation efficiency achieved by the retention basin. For many areas, a minimum drainage area of 20 to 25 acres should be adequate to ensure adequate dry weather inflows. For regional SWMFs, the maximum drainage area should be set at a level which minimizes the exposure of upstream channels to erosive storm flows and also minimizes public safety hazards associated with dam height. A rule of thumb that has been applied to regional retention basin master plans is to restrict the maximum drainage area to 100 to 300 acres depending on the amount of imperviousness in the SWMF watershed. This drainage area range is considered adequate to prevent excessive streambank erosion upstream of the regional SWMF. Highly imper- vious drainage areas will typically be restricted to the lower end of the range (100 acres) and vice versa. Revised 1/96 Storm Water Management Guidance Manual Page F - 31 Public Works Specifications and Standards Soil Permeability Highly permeable soils may not be acceptable for wet detention basins due to the greater potential for excessive drawdown of the permanent pool during dry periods and associated aesthetic problems. However, successful operation of a wet retention basin SWMF without severe drawdown has been demonstrated at NURP testing sites underlain by relatively permeable soils. In cases where relatively permeable soils are encountered, drawdown rates can be minimized by compacting the permanent pool soils during construction. The planning of individual wet retention basins must be performed in coordination with a watershed wide stormwater management study. The location, size, and outlet structure design of detention basins will be developed to not only provide the desired control at the retention basin site, but also to provide the maximum benefits throughout the watershed. Dam and Embankment Fill Material. The dam or embankment should be constructed of materials with sufficient strength to remain stable and with low permeability to prevent seepage of water through the embankment. A clay core can also be used in the center of the embankment where local fill is not adequate to prevent seepage. Foundation Cutoff Trench. In order to prevent undermining of the dam by seepage, a cutoff trench backfilled with clay should be built into the foundation of the embankment if naturally impervious soil is not located at the dam site. Revised 1/96 Storm Water Management Guidance Manual Page F - 33 Public Works Specifications and Standards through the spillway from impinging on the toe of the dam or principal embankment structure. Inflow/Outflow At inflow points energy dissipaters such as riprap should be used to reduce the velocity of flow. The outflow channel below the pipe outfall should be designed to protect against erosion and scour from high velocities and turbulence. Riprap should be provided at the points of discharge as necessary. Vegetation The embankment, emergency spillway, spoil and borrow areas, and other disturbed areas should be stabilized with vegetation. No trees should be allowed to grow on the embankments. Where feasible a shallow marsh around the perimeter of the permanent pool can be established. A 20 to 25 foot buffer strip around the wet retention basin should be established with low maintenance grasses and shrubs. The elevation 'of the dry weather normal water level shall not be lower than the 10-year high tide elevation of the downstream outfall system to prevent backflow of saltwater into the proposed retention SWMF which would kill vegetation already acclimated to a fresh water environment. If required, erosion control mats should be biodegradable within vegetated areas. Safety and Aesthetics All possible safety precautions should be taken especially in heavily populated areas, and local ordinances on health and safety must be followed. Steep side slopes should be avoided and dangerous outlet structures should be protected as necessary. The embankment and basin shall be fenced where deemed necessary and warning signs should be used when appropriate. A well designed and properly vegetated wet retention basin can provide an aesthetic improvement to the local areas. Revised 1/96 Storm Water Management Guidance Manual Page F - 35 Public Works Specifications and Standards areas. Borrow areas should be graded to provide adequate drainage from the site. Erosion and Sediment Control Construction practices should comply with the City's Erosion and Sediment Control Code. Construction plans should provide details of the control measures and their locations to be employed during construction. 4 . 1. 6 MAINTENANCE Inspections The Department of Public Works administers a reinspection and monitoring program (City of Virginia Beach, 1990) for all structural SWMFs within the City of Virginia Beach (public and private) to ensure that regular maintenance is performed by the responsible party. The SWMF reinspection and monitoring program helps ensure that maximum pollutant removal efficiencies are obtained as well as the maximum life of the device is achieved. The SWMF reinspection and monitoring program covers all types of SWMFs constructed in the City including wet retention basins. The City has established the life expectancy and the minimum and optimum inspection schedules for wet retention basins. The life expectancy of a wet retention basin is 15 to 20 years. The minimum inspection schedule calls for an inspection one year after the wet retention basin is accepted and every five years thereafter. The optimum inspection schedule calls for an inspection one year after acceptance and every two years thereafter. In addition, site inspection criteria have been Revised 1/96 Storm Water Management Guidance Manual Page F - 37 Public Works Specifications and Standards Nonroutine Maintenance Nonroutine or corrective maintenance refers to a rehabilitative activity that is not performed on a regular basis. Erosion and Structural Repair Areas of erosion and slope failure should be filled and compacted, if necessary, and reseeded as soon as possible. Eroded areas near the inlet or outlet should be revegetated and, if necessary, be filled, compacted and reseeded or lined with riprap. Damaged side slopes and embankments should be repaired using fill dirt of adequate permeability. Major damage to inlet/outlet and riser structures should be repaired as soon as possible. Access to wet detention basins is necessary for excavating equipment, trucks, mowers, and personnel for routine maintenance and erosion repair and for the removal of sediment accumulation. Where access is particularly difficult or impractical, basins should be overdesigned to allow for sediment accumulation. Sediment Removal and Disposal Sediment removal is a very important maintenance activity because wet retention basins are designed to remove pollutants by sedimentation. Sediments collect at the bottom of the basin reducing storage volume, and accumulated sediment can reduce the pollutant removal efficiency of the basin.

Criteria established by the Soil Conservation Service (SCS, 1984) and the U. S. Army Corps of Engineers (COE, 1965; COE 1980) should also be considered. Table 4-3 outlines the recommended design criteria for extended dry detention basins. Separate criteria are presented for onsite and regional SWMFs. The following is a summary of general criteria for extended dry detention basins. Storm Water Management Guidance Manual Page F - 43 Public Works Specifications and Standards Storage Requirements and Release Rates Extended dry detention basins that provide erosion and flood control in addition to water quality management will have different storage requirements and release rates for each function of the detention basin. Water Quality Management Since pollutant removal is achieved primarily by sedimentation, the basin must have ample volume, area, and detention time to allow for sufficient setting. A volume resulting in a dewatering time of 24 hours is recommended. Table 4-4 summarizes recommended extended dry detention volumes for a 24-hour maximum detention times. Peak Flow Control The storage required for erosion and flood control should be based on maintaining the existing development peak discharge for the future development watershed conditions. It may also be desirable to reduce the peak release rate from the detention basin to less that the existing development peak rate in order to achieve watershed wide erosion/flood control goals. The design storms for peak flow control are presented in the Public Works Design Guide and the Stormwater Management Ordinance.

A clay core can also be used in the center of the embankment where local fill is not adequate to prevent seepage. Foundation Cutoff Trench In order to prevent undermining of the dam by seepage, a cutoff trench backfilled with clay should be built into the foundation of the embankment if natural impervious soil is not located at the dam site. Settlement The height of the dam should be designed to allow for settlement. Additional fill material in order of 10 to 15 percent should be taken into consideration. Top Width and Side Slopes The top width of the dam should be based on the total height of the embankment. For heights of 10 feet or less, the minimum top width should be 6 feet. For heights of 20-24 feet the minimum top width should be 12 feet. Side slopes should be designed for stability and maintenance requirements. They should be on the order of 4:1 or 5: 1 (horizontal to vertical) . kevised 1/96 Storm Water Management Guidance Manual Page F - 49 Public Works Specifications and Standards Inflow/Outflow At inflow points, energy dissipaters such as riprap should be used to reduce the velocity of flow. The outflow channel below the pipe outfall should be designed to protect against erosion and scour from high velocities and turbulence. Riprap should be provided at the points of discharge as necessary. Vegetation The embankment, emergency spillway, spoil and borrow areas, and other disturbed areas should be stabilized with vegetation. No trees should be allowed to grow on the embankments. A 20 to 25 foot buffer strip around the extended dry detention basin should be established with low maintenance grasses and shrubs. The elevation of the invert or bottom of a dry detention basin shall not be lower than the 10-year high tide elevation of the downstream out fall system to prevent backflow of saltwater into the proposed retention SWMF which would kill vegetation already acclimated to a freshwater environment. See Appendix E for 10- year high tide elevations. Safety and Aesthetics All possible safety precautions should be taken, especially in heavily populated areas, and local ordinances on health and safety must be followed. Steep side slopes should be avoided and dangerous outlet structures should be protected as necessary. The embankment and basin shall be fenced where deemed necessary and warning signs should be used when appropriate. Revised 1/96 Storm Water Management Guidance Manual Page F - 51 Public Works Specifications and Standards Erosion and Sediment Control Construction practices should comply with the City' s Erosion and Sediment Control Code. Construction plans should provide details of the control measures and their locations to be employed during construction. 4.2 . 6 MAINTENANCE Inspections The Department of Public Works administers a reinspection and monitoring program (City of Virginia Beach, 1990) for all structural SWMFs within the City of Virginia Beach (public and private) to ensure that regular maintenance is performed by the responsible party. The SWMF reinspection and monitoring program helps ensure that maximum pollutant removal efficiencies are obtained as well as the maximum life of the device is achieved. The SWMF reinspection and monitoring program covers all types of SWMFs constructed in the City including extended dry detention basins. The City has established the life expectancy and the minimum and optimum inspection schedules for extended dry detention basins. The life expectancy of an extended dry detention basin is 10 to 15 years. The minimum and optimum inspection schedule calls for an inspection once per year. In addition, site inspection criteria have been developed and include: • No bare spots on SWMF slopes or in surrounding . buffer. No significant erosion of bank slopes. • Water levels should be recorded over several days after rainfall. Basin should be designed to store a 1-3 inch rainfall event and discharge in not less than 24 hours and not more than 72 hours. • All trash and debris should be removed. Revised 1/96 Storm Water Management Guidance Manual Page F - 53 Public Works Specifications and Standards Erosion and Structural Repair Areas of erosion and slope failure should be filled and compacted, if necessary, and reseeded as soon as possible. Eroded areas near the inlet or outlet should be revegetated and, if necessary, be filled, compacted and reseeded or lined with riprap. Damaged side slopes and embankments should be repaired using fill dirt of adequate permeability. Major damage to inlet/outlet and riser structures should be repaired as soon as possible. Access to extended detention basins is necessary for excavating equipment, trucks, mowers, and personnel for routine maintenance and erosion repair and for the removal of sediment accumulation. Where access is particularly difficult or impractical, basins should be overdesigned to allow for sediment accumulation. Sediment Removal and Disposal Sediment removal is a very important maintenance activity for dry extended detention basins because these facilities are designed to remove pollutants by sedimentation. Sediments collect at the bottom of the basin reducing storage volume and increasing the likelihood of clogging the orifices of the extended detention outlet structure. Dry extended detention basins may have to be cleaned out more frequently than wet detention basins for aesthetic reasons. 4 . 3 INFILTRATION BASIN 4. 3 . 1 DESCRIPTION An infiltration basin is a water impoundment formed by constructing a dam or an embankment or by a combination of excavation and an embankment in or on relatively permeable soils.

G : 4 rylry1 N I i r 1-53 Public Works Specifications and Standards Infiltration basins have relatively large surface area requirements. Depths of infiltration basins should generally range between 3 to 12 feet. Infiltration basins should be situated on soils which will infiltrate a minimum of about 36 inches of stored runoff over a 3 day period. In addition, infiltration basins should be located in areas where the seasonally high water table and bedrock are at least 2 to 4 feet below the surface. 4 . 3 .4 DESIGN CRITERIA The design criteria for infiltration basins should be based on local criteria and standards for impoundments. Criteria established by the Soil Conservation Service should also be considered. The following is a summary of general criteria for infiltration basins. Infiltration Rate Saturated soil infiltration rates must permit adequate percolation of stored runoff. Typical values based on soil texture classifications are shown in Table 4-5. Ideally, this value should be measured in the field by an appropriate method. It is recommended that infiltration basins be restricted to sites with minimum infiltration rates of about 0. 3 in/hr (i.e. , silt loam soils in Table 4-5) within the underlying and surrounding soil profile. Dewatering Time The maximum allowable dewatering time should minimize the risk of carryover runoff storage between rainstorms. If the infiltration facility requires an excessive amount of time to dewater, storage will not be available for runoff from subsequent rainstorms. The infiltration basins should be designed to completely drain the stored runoff within 3 days, in a maximum 72-hour dewatering period.

Revised 1/96 Storm Water Management Guidance Manual Page F - 61 Public Works Specifications and Standards Emergency Spillway_ For infiltration basins created by the construction of an embankment, an emergency spillway should be provided to pass the flow from a 100-year storm with one-foot of free board to the top of the dam. The embankment, emergency spillway, spoil and borrow areas, and other disturbed areas should be stabilized with vegetation. A dense turf of water tolerant grass should be established on the floor and sides of the basin to promote infiltration and prevent erosion and scouring. No trees should be allowed to grow on the embankments. A 20 to 25 foot buffer strip around the infiltration basin should be established with low maintenance grasses and shrubs. Safety and Aesthetics All possible safety precautions should be taken, especially in heavily populated areas, and local ordinances on health and safety must be followed. Steep side slopes should be avoided and dangerous outlet structures should be protected as necessary. The embankment and basin shall be fenced where deemed necessary and warning signs should be used when appropriate. 4. 3 .5 CONSTRUCTION CONSIDERATIONS Protection of Device During Construction In order to preserve natural infiltration rates at the infiltration basin site, particularly for basins with embankment dams, the site should be roped off to prevent the entry of heavy construction traffic which would cause excessive compaction of the soil. Initial Excavation Initial excavation should be carried out with light-weight equipment to minimize compaction of the soil profile. Where possible, excavation should take place from the sides of the device rather than from the device floor. Excavated materials should be placed a sufficient distance from the sides of the device to help prevent side failures and also to prevent migration of soil particles back into the device. Excavation in clay soils (clay content > 25 percent by weight) should Revised 1/96 Storm Water Management Guidance Manual Page F - 63 Public Works Specifications and Standards dissipaters such as riprap may be required to help control erosion near the inlet. Outlets should be designed to protect against erosion and scour due to high velocities. Riprap should be provided as needed along the outflow channel. Tilling Tilling is recommended after basin construction has been completed to restore natural recharge (infiltration) rates to compacted soils. Tilling should be accomplished using light-weight equipment (e.g. , small tractor) with rotary tillers or disc harrows. If heavy equipment has traversed the infiltration area, tilling should be preceded by deep plowing. A leveling drag should be towed behind the equipment on the last pass to ensure a level and smooth infiltration surface, which will facilitate future cleanout operations. Lining Infiltration basins may be lined with a 6- to 12-inch layer of filter material such as coarse sand in order to prevent the buildup of impervious deposits on the natural soil surface. To increase the permeability of clayey soils, a 6-inch layer of coarse organic material is sometimes specified for dicing or spading into the soil. 4. 3 .6 MAINTENANCE Inspections The Department of Public Works administers a reinspection and monitoring program (City of Virginia Beach, 1990) for all Storm Water Management Guidance Manual Page F - 65 Public Works Specifications and Standards infiltration basin. Following reinspection, a "notice to comply" form is completed which establishes the necessary maintenance requirements. Inspection criteria, frequency of inspection and maintenance scheduling also are presented in the SWMF manual, "Stormwater Management Facilities (SWMFs) Evaluation Report Associated with Design - Maintenance - Monitoring - Inspections. " Routine Maintenance Grass can be mowed occasionally if desired. Grasses of the fescue family can be mowed twice per year, in June and September. In addition to grass maintenance, any other vegetation in the infiltration basin area or access area which has reached nuisance levels (e.g. , bushes and weeds) should be trimmed or removed. Fertilization activities may not be necessary due to the nutrient concentrations in the runoff. If the inspector determines that the dewatering rate is too slow, the basin should be tilled. It is anticipated that tilling operations will be required about once a year. Before the basin can be tilled, however, all accumulated sediment must be removed. Sediment should be removed using light equipment only after the layer has dried, cracked, and separated from the natural floor of the basin. After the sediment accumulations have been carefully removed, tilling should be performed using the methods outlined above for construction practices. In some cases sand or organic matter can be tilled into the soil to increase the infiltration capacity.

Upon motion by Councilman Baum, seconded by Councilman Heischboer, City Council DENIED: Application of the CITY OF VIRGINIA BEACH to AMEND the City Zoning Ordinance: Section 111 of the City Zoning Ordinance re definition of correctional facility Section 801 of the City Zoning Ordinance by ADDING correctional facilities as a conditional use in the 0-2 Office District. City Council referred this issue to the Planning Commission for study/recommendation re privately-owned correctional facilities. The recommendations shall be returned within 120 days [25 August 1996]). Councilman Baum's Motion: " Under the present City Zoning Ordinance, correctional facilities are allowed in Office Districts, including the Municipal Center, but only if they are operated by the government. Correctional facilities operated by private entities are not allowed in any zoning district. However, we all recognize that there is a need for correctional facilities, and that in some cases, it may be more economical for these facilities to be operated by private entities, rather than by the City or State. I do not believe that 0-1 or 0-2 zoning is appropriate for this type of facility, but I do think that we should make some provision for allowing privately-operated facilities to be located within the City. For those reasons: I move that we deny the ordinance amendments but request the Planning Commission and Staff study the issue and make recommendations as to appropriate zoning regulations pertaining to private correctional facilities within 120 days from today".

If not necessary, the City Attorney shall schedule a Public Hearing for the City Council with all interested parties appropriately notified. City Council hopes this can be completed within 60 days. April 23, 1996 - 39 - CITY COUNCIL CONCERNS ITEM #40696 Councilman Baum expressed concern relative the erection of No Wake Signs on Blackwater Creek near Blackwater Road. There are only three homes affected The boaters are showing contempt for the signs with racing and vulgar hand signs. The marine patrol will not be there until after Memorial Day. Councilman Baum suggested one of the residents videotape the boaters. Councilman Baum requested the City Manager provide a report to City Council. ITEM #40697 Council Lady Parker referenced the technology issue and the establishment of a pilot program. Council Lady Parker had spoken with David Sullivan, Director of Information Technology, and advised Council Members Strayhorn, Jones, Dean and herself had agreed to be a test pilot program. ITEM #49698 Council Lady Parker referenced the City's response to the correspondence of Reservations Plus. Council Lady Parker referenced Item No. 7: "Possible that Operations will cease once volume exceeds the amount negotiated: All offerors were asked to place a "cap" on the amount of financial exposure (risk) to the City under their pricing plan. ITT Global ConNextion's pricing plan proposed a beneficial partnership that shared the risk and profits of the services and put the City at significantly less financial risk" Council Lady Parker requested this item be explained and identify the City's potential risk exposure on this particular process. The City Manager advised another letter has been received from Reservations Plus, and copies of same will be provided City Council. ITEM#49699 Council Lady Parker referenced a telephone call relative a sign variance granted by the Board of Zoning Appeals to the Amphitheater. She was concerned that no one in the City took a legal position at the BZA on the sign. The original request was for 40 feet high and a 120 square foot per sign face. After review by the Advisory Review Committee, the sign was reduced to 30 feet high and 65 square foot per sign face. Councilman Harrison and Branch advised the sign is not visible from Princess Anne Road. It is an entrance feature composed of two steel columns, pulling together the architecture from the facility to the front side of the berm. Cellar Door paid for this entrance feature. The City Manager advised this is actually a sculpture. Assistant City Attorney Macali advised if this were an ordinary sign, the City may have problems with precedent; however, information presented has shown this not to be the case. April 23, 1996 - 40 - CITY COUNCIL CONCERNS ITEM #49700 Council Lady Strayhorn referenced telephone conversations from residents on Colechester Road relative the "fish pond". The citizens were concerned relative City Council's actions after the 90-day enforcement of the weight limit on Colchester Road. On April 2, 1996, Assistant City Attorney Vanessa Valldjuli advised pursuant to Section 21-204 of the City Code, the Department of Public Works performed an engineering study of Colchester Road and recommended the maximum weight limit upon this road should be eight (8) tons. The engineering study disclosed the recent operation of commercial vehicles over Colchester Road seriously damaged the road and rendered it unsafe for all vehicular traffic. Signs stating the eight (8) ton weight limit shall be erected immediately at each end of Colchester Road. This will be effective for 90 days. Enforcement of this weight limit will ensue immediately upon the posting of the aforesaid signs. Council Lady Henley advised an 8-ton weight limit is not a solution, as this will mean the residents would not be able to have City services. A garbage truck certainly weights more than 8 tons. The City Attorney advised his office, Public Works and Planning are coordinating and will provide a status report to City Council. ITEM #49701 Council Lady Strayhorn referenced a concern of citizens attending her Town Meeting, The citizens did not see the need to do away with the names of the Boroughs simply because there were District Numbers available.

Smith DEPARTMENT: PW/Engineering SUBJECT: Public Works Council CIP Briefing on April 23, 1996 During the Public Works CIP briefing to City Council on April 23, 1996, issues were raised with respect to bike path coordination with roadway projects, ranldng criteria for storm water projects, and the Southeastern Parkway and Greenway project Architectural and Engineering selection process. The following information is provided in response to the three issues. In its implementation of the Roadways CIP, Public Works looks to the Planning Department for guidance on which Roadway projects should incorporate bikeways. The Planning Department's 1986 Master Bikeway Plan (copy attached) and Master Street and Highway Plan (MSHP) are the initial sources utilized by Public Works. Additionally, during the design of a Roadway project, Public Works Project Management staff consults with the Planning Department staff for input on bikeway design and for guidance on whether to include a bikeway even if none is shown on the 1986 Master Bikeway Plan or the MSHP. The following Roadway CIP projects currently are programmed to include bikeways: 2-149 Birdneck Road II 2-270 Constitution Drive Extended 2-174* Dozier's Bridge 2-152* Elbow Road Extended 2-096* Ferrell Parkway Phase V 2-137 Great Neck Road/London Bridge Road 2-219 Independence Blvd Phase IVC 2-095 Indian River Road Phase VI 2-256 Indian River Road Phase VII 2-136 International Parkway 2-279* Kempsville Road/Providence Road Intersection 2-139 Kempsville Road Phase III 2-140 London Bridge Road Phase II 2-132 London Bridge Road Extended 2-167 Lynnhaven Parkway Phase XI 2-930 Salem Road * MSHP did not call for bikeway Mr. Spore May 9, 1996 Page 2 With respect to deterioration of the storm drainage system, the majority of the City's drainage system has been constructed with concrete pipe and structures and is in relatively good condition. However, as Public Works ranks the storm water projects and deterioration of the system has been identified in a project area, the condition of the system is considered under the Urgency criteria which includes evaluation for a dangerous situation and the likelihood of causing degradation to the environment or property. Attached is a copy of the 1996-97/2001- 2002 Storm Water Capital Improvements Program Project Priority (dated 4/17/96) and page 1 of the Storm Water Projects Section of the proposed Capital Improvement Program which contains the RankinEi System and Criteria.

Items considered for a project include a project's ability to reduce environmental degradation from storm water run-off and frequency of flooding. - This criterion measures the extent to which a prior commitment has been made by the city to a project and/or the extent to which a project will relieve a dangerous situation. Included in this criterion is the importance of a project in ensuring access to major transportation routes in storms, and the likelihood of storm activity causing further degradation of the environment or property. qorvi&A And Rannfit - This Criterion Measures the number of people who will benefit from the project, both directly and inchrectiy, and the associated costs. Boments considered in the rating include the project type (water quality versus water quantity; large versus small; residential versus non-residential) and the area of the service. rnmprnhnne*vp Plan rnmpnt*hol;tv - This criterion is a measure of land use impact of a particular project and project consistency with current land use policies. - This criterion addresses the project's impact on the city's aesthetic qualities, natural environment, and neighborhoods. at rqtimnta nofinitonm a of project cost estimates are defined as follows: R,,dgatarg rnat F:etimaton - Based on general layouts and approximate costs per lineal foot of similar projects previously constructed.

An expanded system of bikeways in Virginia Beach would provide better facilities for the growing number of cyclists by developing an infrastructure of facilities which encourages bicycle use, addresses the demand for bicycle commuting, provides for a greater number of utilitarian bicycle trips, and improves bicycling safety. Although Virginia Beach had constructed a number of bikeways before this Plan was first adopted, they had not been part of a coordinated system. The Comprehensive Plan for Virginia Beach, adopted in 1979 and revised in 1985, provided for a major bikeway system by recommending the development of a Bikeway Plan as a major functional component of the Comprehensive Plan. Specifically, the Comprehensive Plan calls for the provision and maintenance of a bikeway network for the City; "The City of Virginia Beach is committed to the development of a transportation system comprised of different yet compli- mentary "modes" such as streets and highways, fixed-route bus, trolleys, passenger rail, bikeways and pedestrian walkways in locations and combinations which emphasize smooth traffic flow for convenient and safe access to residential, commercial, employment and recreational centers." The Comprehensive Plan, as revised in 1985, states City policy on bikeways: "The City has adopted a Bikeway Plan for the development of a master system of bike paths throughout the City. These Bikeways will use existing streets as well as independent rigbts-of-way. Wherever appropriate, new bikeways will be constructed as part of highway improvement projects." This Revised Bikeway Plan is in direct response to the policies established in the Comprehensive Plan. The Plan is intended to satisfy, over a period of time, the biking needs of the public. This Bikeway Plan is the official guide for bikeway construction in Virginia Beach. Bicycles are used for both transportation and recreational purposes. With the diversity of interest and skill levels among cyclists, the demands on a bikeway system are neither uniform nor constant. This Bikeway Plan addresses the some of the needs of all bicyclists, recognizing that it is not possible to satisfy totally the needs of anv one group. The planned Bikeway system is designed to 'provide for a balanced blend of facility types, and the selection of facility type (path, lane or route) is based on the demand anticipated for the facility. I THE PLAN In developing the publication "Guide for Development of New Bicycle Facilities: 1981," The American Association of State Highway and Trans- portation Officials (AASHTO) defines a BIKEWAY as ffany road, path, or way which in some manner is specifically designated as being open to bicycle trave4 regardless of whether such facilities are designated for the exclusive use of bicycles or are to be shared with other transportation modes." A "bikeway system" is " .. a series of bikeways laid out to link various areas of the City in a manner consistent with the adopted priorities in the goals and policies." To address the adopted goals and policies of the City, the Bikeway Plan for the City of Virginia Beach consists of the following elements: 0 A map and description of planned routes which fulfill the goals and policies and make up the bikeway "system". 0 An implementation process 0 A set of guidelines to phase the development of the bikeway system over time. * Design criteria to guide construction. THE CONCEPT The Bikeway Plan provides for a continuous and coordinated network of bicycle routes. This network is composed of nine Study Area systems which separately provide bicyclists access to the activity centers within each Study Area, and which combined form a continuous City-wide bikeway system. The City-wide bikeway circulation system is linked to and complemented by a major east-west route - the Norfolk Southern Railway line. Within each of the nine Study Area systems, bicycle routes have been categorized as primary, secondary and neighborhood routes. "Primary routealff, serving as the Study Area trunk lines, provide cyclists a direct and continuous route traversing the entire Study Area (See Map). ndary routesm function as connectors between activity centers, major population concentrations and primary routes. wneighborbood routes" facilitate internal neighborhood movement and serve as links between secondary routes and activity centers. In brief, the major components include: A series of primary bikeway routes within each Study Area. A system of secondary routes which provide for a smooth connection between primary bicycle routes. 2 0 An internal system of neighborhood routes which tie into the secondary routes in each Study Area. 0 An east-west corridor route along the Southern Railway line. 0 A north-south corridor route along the Virginia Power/Virginia Department of Highways and Transportation Right-of-Way from Mount Trashmore Park to Munden Point Park. The bikeway system improvements are constructed to the following classi- fication standards: Bike Path-. Separate trail facility or separated Bikeway/walkway. Bike Lane: Signed and striped lane along the roadway. Bike Routes Marked route with adequate shoulder. Some bicycle routes may consist of more than one class due to varying street widths, rights-of-way or parking conditions. Unlike the first Bikeway Plan adopted in 1981, this proposed revised Plan does not attempt to prioritize all bikeway improvements. The experience of the past few years has shown that priorities can change from year to year, and that this document cannot anticipate the policies which will guide capital programming for the next 4 to 5 years. The Capital Improvement Program will be the instrument for the timing and funding of the individual bikeways. In establishing a process for the phasing of bikeway construction, the Capital Improvement Program (CIP) will attempt to address both the need to meet immediate problems and the need to implement a Citywide bikeway system. It should be noted that some bikeways will be constructed in conjunction with future road projects and thus cannot always be timed according to a phased program involving bikeways only. By programming bikeway projects through the CIP process, the actual programming of projects will be sensitive to any changes in priorities, and the implementation of the bikeway system will be more responsive to the recognized need for bicycle facilities. 3 PUBLIC DEMAND FOR BIKEWAYS The need for communities in Virginia to develop Comprehensive Bikeway Plans has been a growing issue since the mid 1970's. In 1974, the Virginia Department of Highways and Transportation prepared a report, The Bikeway Development Study, which recommends legislative programs to fund the planning and construction of bikeways at the local and regional level. In May, 1976, the Southeastern Virginia Planning District Commission in conjunction with the local Planning Departments, prepared the "Bikeway Plan and Guidelines for Southeastern Virginia". This document incorporated bikeways identified by the City of Virginia Beach. Bikeway projects were identified as part of the regional transportation planning process to enable the bikeway projects to be eligible for Federal and State Highway Funds. More recently, the Trails Element of ffthe Regional Open Space Plan" prepared by the Southeastern Virginia Planning District Commission in 1979, included proposals for both recreational and commuter bikeways. The Trails Element proposes increased coordination within and between local jurisdictions and the integration of bikeway planning with the regional transportation system. Prior to adoption of the Bikeway Plan in 1981, Bikeways had been considered on an individual basis, rather than as part of a comprehensive system. The City of Virginia Beach has been successful in constructing more than 22 miles of bikeways. This figure includes bikeways of Bike Paths, Bike Lanes and Bike Routes. The existing bikeways are located in the following areas: Oceanfront - (including Seashore State Park) Bike Path, Bike Lane and Bike Route Total Distance - 13.3 miles Great Neck Bike Lane and Bike Route Total Distance - 6.0 miles Mount Trasbmore Bike Route Total Distance - .6 miles Little Neck Bike Path Total Distance - 3.4 miles General Booth Boulevard Bike Path Total Distance - 3.1 miles Witebduck Road Bike Path Total Distance - 2.2 miles Diamond Springs Road Bike Path Total Distance - 1.7 miles KempwMe Road Bike Path Total Distance - 1.8 miles Park Connector Bike Path and Route Total Distance - 4.85 miles Lynnhaven Parkway Bike Path Total Distance - 2.5 miles The adoption of the policies in the Virginia Beach Bikeway Plan which provided for the construction and maintenance of a bikeway system represented a major change in the planning, funding, and improvement of bikeways in Virginia BeaciL It was also one of the first efforts by any local jurisdiction in this region to actually develop a comprehensive bikeway system. TRENDS Since the. adoption of the Bikeway Plan in 19819 interest in bicycling has continued to increase. The reasons for the sustained interest in both utilitarian and recreational bicycling trips include: 0 Concern for physical fitness 0 Concern for improved air quality 0 High cost of gasoline 0 Concern for energy conservation 0 Cost of alternative recreation opportunities 0 Parking cost and congestion Assuming the current trends in bicycling continue, a sustained effort must be made to plan for the increased demand for bikeways and other bicycle facilities. 5 SAFETY The bicycling accidents resulting in the most severe injuries are those involving bicycle/motor vehicle collisions. Bikeways contribute to bicycle safety chiefly by separating bicycles from motor vehicle traffic, by either providing a separate bicycle facility (Bike Path), or providing a clearly marked area for bicycle traffic on a shared roadway (Bike Lane). Bicycle/motor vehicle conflicts can thus be avoided or minimized and non-intersection accidents decreased. It should be noted that 91% of the reported bicycle accidents involved personal injuries, and that there were three bicycling fatalities in the City during the past four years. Bikeway signing may also improve safety conditions by making motorists more alert to the possible presence of cyclists (Bike Routes). Even such improvements as wide curb lanes and paved shoulders can increase safety by providing more space and a better riding surface for cycling. The bicycling safety record in Virginia Beach has displayed a marked improvement since the adoption of the first Bikeway Plan. That document stated that the average number of reported accidents involving bicycles between 1977 and 1979 was approximately 7.9 per montfu For the years 1981 through 1984, the monthly reported accident rate was 7.4 - a decrease of six percent. Furthermore, these statistics are more impressive when considering that the population of the City increased by approximately 60,000 between 1977 and 1984. Clearly, the record on bicycle safety is improving. The credit for the impressive safety record must go to all those involved in and concerned about bicycle safety. INCREASED USEAGE In Southeastern Virginia, bicycling is cited as one of the top four outdoor recreational activities and is only surpassed by beach use. The nature of the usage could also change with utilitarian trips gaining in importance relative to recreational trips. Utilitarian trips include bicycling as an alternative mode of transportation to a place of employ- ment, schoolsg stores or a community activity center. in other cities, surveys of bicycle patterns have found that additions to the bikeway network induced 38% of those surveyed to expand their use of the bicycle for utilitarian trips. Recreational bicycle trips include the use of bicycles for health purposes, exercise or general pleasure. Recreational trips currently constitute the majority of the bicycle trips in Virginia Beach, a trend which is due in part to the resort orientation of the City. An expanded system of bikeways would provide better facilities for bicyclists, encourage increased use of bicycles, increase the number of utilitarian trips made by bicyclists 6 and improve safety conditions for all bicyclists. Once the Revised Bikeway Plan is adopted by The city of Virginia Beach, the routes will be incorporated into the Regional Open Space Plan and the Regional Bikeways Facilities Plan, ensuring eligibility for state and federal funding. 7 GOAL STATEMENT The following goal and policies are set forth to guide future decisions and to identify actions for implementation. The goal outlines a desired future accomplishment, while the policies state those actions necessary for goal achievement. GOAL A CONTINUOUSY SAFE AND COORDINATED SYSTEM OF BIKEWAYS AND BICYCLING FACILITIES PROVIDING ACCESS TO MAJOR RECREATIONALT EMPLOYMENTO EDUCA77ONAL AND COMMERCIAL ACTIVITY CENTERS IT IS THE POLICY OF THE CITY OF VIRGINIA BEACH TO: 0 Coordinate the Virginia Beach Bikeway with the Regional Bikeway System for Southeastern Virginia. Develop a Bikeway System which addresses the full range of bicycle uses - both recreational and utilitarian. 0 Include a bikeway facility as part of a road improvement construction project wherever so indicated on this Plan. Design and construct bicycle facilities in accordance with the guidelines developed by the American Association of State Highway and Transportation officials (AASHTO) and endorsed by the Federal Highway Administration. To view bikeways in this Bikeway Plan in the same manner as streets are viewed in the Master Street And Highway Plan during the plan, subdivision and site plan review process. 0 To require dedication of bikeways when the bikeway passes through or adjacent to developing property. 0 To require construction of bikeways when the bikeways passes through or adjacent to a developing property and that development will generate the need for the bikeway. 0 To consider bikeway projects for evaluation in prioritizing projects for the Capital Improvement Program. 0 To program only those bikeway facilities which are included in this Plan either as adopted or amended. 8 0 To include neighborhood bike lanes and routes in the development of new subdivisions which cannot be anticipated by this document. These facilities are to be identified during the development review process for new subdivisions, and are to be specified in the preliminary subdivision approval 9 BIKEWAY SELECTION METHODOLOGY To develop a bikeway system that would be both comprehensive in nature and meet the needs oi individual communities, a procedure for rating individual routes and then determining which of those routes would be incorporated in the overall strategy was developed. The following steps were taken in rating potential routes: Identify routes and activity centers which are likely to attract substantial bicycle traffic. 2. Evaluate alternative route locations. 3. Evaluate routes with respect to safety conditions. 4. Evaluate routes with respect to the physical design and planning limitations, including fiscal impacts and liability concerns. Recommend type and location of routes. A discussion of the selection of appropriate types of bikeways and the necessary trade-offs involved for each type of 6fkeway follows. CRITERIA UTILIZED IN ROUTE SELECTION PROCEDURE The purpose of using criteria in the selection procedure is to provide an objective means for establishing a balanced bikeway system. Since the cost of implementing a "perfect" bikeway system which overcomes every physical barrier and safety hazard would be prohibitive, the criteria are developed and used to consider those characteristics of a bikeway which are most important A goal of the Plan is to achieve the optimum service levels within available resources and constraints. The following sections describe how the optimum route locations and class levels are selected. 1. Demand Criteria To establish an initial concept of a bikeway network, anticipated demand, trip origins and destinations and connections to other routes were the primary factors considered. Trip origins and Destinations - Routes which could be used to connect high density areas to all major activity centers receive high ratings. Activity centers include the Oceanfront, employment locations, schools, libraries, recreational centers, local and regional parks and major shopping centers. Proposed bikeways link these activity nodes to major population concen- trations in the City. 10 * Demand - The anticipated volume of bicycle trips for given routes is a factor in rating routes. Utilitarian and recreational trips are rated equally. * Linkage with other Routes - Accessibility and continuity are considered important factors in developing a bikeway system for the City. Even a well designed bikeway facility can make travel slow and inconvenient by requiring detours or deviation around landscaping features. When not tied into other bike routes, a bikeway's usefulness is limited. Those routes which provide the most direct link between activity centers and high density residential areas receive high ratings as do those routes which link neighborhood routes to primary connecting routes. 2. Alternative Route Locations Alternative locations for bikeways are considered. The choice of an alternative bikeway route depends to some extent upon the type of bikeway proposed. lmwse residential or business streets with a low volume of traffic and low traffic speed are the most obvious routes to be initially included in the evaluation process as stated above. However, a number of other locations exist that could easily be converted or adapted into bikeway routes. For example, bikeways which are situated away from vehicular traffic could provide cyclists with more safety and aesthetic appeal. All of the following locational considerations are evaluated for potential use based upon terrain, demand and viability of the alternative to provide a better quality bikeway than other alterna- tives. * Existing railroad rights-of-way - Existing railway rigbts-of-way have been used to develop Bike Path facilities elsewhere. The advantage in using existing railroad rights-of-way will require legal right-of-way agreements between the local jurisdictions and the railway and involves some concern for liability. An additional consideration in the use of railroad rights-of-way is the expense involved in providing a separated bicycle facility. * Telephone and power ]Line righ@-way and easements - Telephone and power line rights-of-way and easements present long,,narrow, cleared strips of land, which, like railroad rights- of-way, could provide excellent locations for Bike Path facilities, particularly for recreational use. However, fragmentation of ownership and liability concerns must be considered (See Park Connector). 0 State and local parks - Parks provide ideal locations for bicycle trails. With their scenic beauty or historical signifi- cance, these facilities offer the cyclist excellent locations for recreational cycling. Especially important are those bikeways linking parks with population centers. Since most parks are publicly owned, acquisition of rights-of-way may be possible 11 through cooperation with the appropriate authorities. * Abandoned roadways - Abandoned roadways may also be considered for bicycle trails. However, they are usually short or dead-ended, limiting their inclusion in a bikeway system. * Sidewalks and pedestrian walkways - Sidewalks and pedestrian walkways which carry low pedestrian volumes may be easily converted to bikeways. In most cases alternatives may be necessary to meet bikeway design criteria, and special treatment may be necessary to obtain adequate horizontal and vertical clearance. 3. Selection of a Facility Type In selecting the type of facility for which to plan, the anticipated purpose of that facility (recreational or utilitarian) was the determinant factor. However, other factors were also considered. They include: 0 Barriers - In some areas there are physical barriers to bicycle travel caused by topographical features, freeways, restricted land use or other impediments. * Accidents - The reduction or prevention of bicycle accidents of all types was a strong factor in facility selection. * Directness - The directness of the proposed route, particularly for primary and secondary routes, is considered to promote ease and convenience. * - Facilities were recommended which provide frequent and easy access by bicyclists. Access is restricted on only a few primary routes. * Attractiveness - Scenic aesthetics and natural settings were considered in selecting facility type (Seashore State Park Path). * Use Co - Efforts were made to avoid conflicts between motorists and bicyclists wherever feasible. Planned routes along Virginia Beach Boulevard were deleted from this revised Plan due to the extensive and intense commercial development. 0 Truck Traffic - Main truck access roads (Lynnhaven Parkway through Oceana West Industrial Park) were avoided. 0 Traffic Volumes wW Speeds - Wherever possible, bikeways were not planned along high speed corridors (Princess Anne Road south of Lynnhaven Parkway). Those segments which do have bikeways planned will provide for a physical barrier between 12 bike traffic and auto traffic. Bridges - The expense of building and maintaining bridge structures mandate that planned separate bicycle structures be minimized. Where indicated in this Plan, street and highway bridges should include provisions for bicycle traffic. late n Conditions - Since a high proportion of bicycle accidents occur at intersections, this Plan attempts to avoid the most intensely developed and congested intersections. Types of Blkeways A bikeway is considered to be any road, street, path or way that is specifically designated as being adequate for bicycle travel, regardless of whether such facility is designated for the exclusive use of bicycles or is to be shared with other modes of trans- portation. Generallyo there are three types of bikeways: bicycle paths, bicycle lanes and bicycle routes. As discussed in the section on safety in this plan, bikeway types were selected for specific routes based primarily upon the volume and speed of traffic. In addition to these safety considerations, several other planning constraints including design, construction and maintenance cost influenced the final selection of bikeway types. The following discussion reviews the basic criteria used in the bikeway classification selection plus the trade-offs involved in that selection process. Paths - A separate route or path designed for the exclusive use of bicycles, or for the combined use by bicyclists and pedestrians. Although usually the most costly, bike paths minimize the exposure of bicyclists to vehicular traffic, thereby providing the safest alternative in bikeways. Bicycle paths are the most convenient and direct as they either parallel major traffic routes or follow more direct, separate alignments. While providing the cyclist with the highest degree of safety - a result of the total separation of bicycles and automobiles - this type of bikeway requires the construction of bicycle paths of acceptable design, the cost of which will vary with right-of-way and construction expenses. In additior4 signs, pavement markings, and in some circumstances, lighting, will be needed to complete bike paths. Also, maintenance cost will be higher with bike paths than with either bike lanes or bike routes. Frequent inspection of the surface condition, along with removal of debris and periodic repainting and stenciling, will all add to the overall cost of bike paths facilities. A combination bikeway/walkway provides an acceptable facility in areas where pedestrian traffic is low and curb cuts are few. 13 Many of the road projects listed in this plan will include a widened sidewalk on one side of the street as a combined use facility. This reduces right-of-way acquisition and damage costs as compared to separated bikeways. Long stretches of continuous right-of-way found in parks, utility easements, railroad easements and along waterways are excellent locations for major collector and recreational bicycle paths. Where right-of-way must be purchased, costs may become prohibitive. When there are many interruptions such as driveways, poles, curb cutst side streets and changes in bikeway type, bike paths may not be likely to receive the use that would justify the cost. Advantages- High degree of safety Convenient and direct route Usually parallels major traffic routes Accommodates commuter, recreational and utilitarian uses Disadvantages: High construction and maintenance costs. Often requires the purchase of additional rigbts-of-way. Bicycle LanOS A portion of the roadway that has been designated generally for the exclusive use of bicycles. This class is usually part of the roadway or shoulder and distinguished by painted stripes, curbing, parking blocks or similar devices. While through-travel by automobiles is prohibited, parking may be allowed. Cost assessments regarding bike lanes are dependent upon route selection and current roadway conditions. The establishment of separate bicycle lanes may, in some instances, require modification of existing streets and acquisition of additional right-of-way. Where these modifications and acquisitions prove too costly, the reevaluation of proposed lanes may be necessary . While all bike lanes, regardless of their location, will require signs, pavement markings and markersp some will warrant modifications such as curb cuts, ramps, physical barriers and signal changes. The type of bike lane used will depend on road width, existence of and need for on-street parking and condition of road sboul- ders. Leaving on-street parking along bike lanes, street width permitting, creates problems which occur with entering and leaving the vehicles or parking space. Removing parking from streets where people have used and depended upon on-street parking causes opposition from residents. Adequate need should be determined before attempting removal of parking. Advantage= More room on road for bicycles increases safety. Automobiles are made aware of bicycle 14 traffic by signs and stripes. Usually less expensive that bike paths Maintenance may t>e included with normal street cleaning activities, depending on separation. Disadvantages. A bicyclist may believe he is safer than he really is. Parking removal may inconveniences residents. Debris may accumulate in bike lanes. Bicycle RouteSA roadway officially designated and marked as a bicycle route but is open to motor vehicle traffic. Because this class shares its traffic right-of-way with automobiles, it is necessary to limit these bicycles routes to residential areas of low traffic volumes as to provide for the safety of the cyclist. Bicycle routes are the least expensive type of bikeway to implement. This is due to the fact that the riding surface of existing roads is utilized and only bikeway signs need to be installed. The acquisition of additional right-of-way is not necessary to make the facility operational. Likewise, maintenance costs are minimal, with only sign posts and panels requiring periodic inspections. These routes are usually minor residential collectors and make connections to schools, parks and other bikeways. They may also occur along major streets at narrow bridges or where parking and right-of-way limitations ezut. Of the three types of bikeways, bicycle routes are the most limited in the additional protection they provide for the cyclist. The designation of bicycle routes is of value where a particular neighborhood route is determined to be preferable to alternative routes as a connecting route or to reach an activity center. Bicycle routes also enhance motorist awareness of bike traffic and provide information to bicyclists concerning destinations. Advantages. Low cost. No parking need be removed. No need for additional right-of-way. Fills functional gaps in bikeway system (i.e., it is the only solution to some problems). Disadvantages: Provides little additional safety. Potential conflicts with parked cars. 15 BIKEWAY ROUTES This section identifies the bikeway routes selected for each Study Area. Maps and tables describe each Study Area Bikeway System.

The process involves both multi-modal transportation planning for meeting an types of travel needs and unimodal planning to meet specific bicycle transportation needs such as park access. It is recognized that the best facilities are those which serve the full range of bicycling needs, and which are heavily used during both business, shopping and recreational hours. The first step in the implementation of this Plan is the actual adoption of the revised Bikeway Plan by the Virginia Beach City Council. The process leading up to that adoption involves an extensive process for citizen and agency participation and review. The major participation and review steps are as follows: 1. PARTICIPATION AND REVIEW CITIZEN The degree of citizen participation in the development and review of this revised Bikeway Plan has been extensive. Firs@ the Mayor's Committee on Bikeways is composed of interested citizens appointed by the Mayor to advise on matters concerning bicycles and bikeways. The draft revised Plan is a document which has been prepared by this Committee. In developing this draft revised Plan, the Committee notified each of the more than 90 Civic Leagues in the City that the revised Plan was being developed, and that any specific concerns and suggestions from the Civic Leagues would be welcome. Several Civic Leagues did respond, expressing their concerns on several proposed bikeways. Those bikeways were subsequently deleted from this revised draft. in contrast, several members of an Oceanfront Civic League expressed an interest in adding a bikeway connecting their neighborhood with the resort area. As a result, the Committee added a bikeway along Norfolk Avenue between the Norfolk Southern Rail Line and the resort area. Through such meetings, the Mayor's Committee has sought to develop a revised Bike Plan which is both sensitive and responsive to the concerns of the Community. The second step in the Citizen Participation and Review Phase involves two formal public hearings. To provide ample opportunity for partici- 41 pation, these hearings were held at the Virginia Beach Pavilion and the Virginia Beach Recreation Center in Kempsville. Notification of these public hearings was listed in the Beacon supplement to the Virginian-Pilot & Ledger Star newspapers. At each hearing, preliminary drafts of the revised Plan were available for public review, and comments were invited. These comments, along with those from other interested organizations, have been considered by the Committee. An appropriate response has been composed for each comment, and in some cases, comments have resulted in changes to this draft revised Plan. INTERESTED ORGANIZATIONS Because the. plans, policies and recommendations in the Virginia Beach Bikeway Plan affect a wide range of organizations and interests, the Mayor's Committee has distributed copies of the draft revised Plan to several interested organizations for review and comment. Some of these organizations include: Hampton Roads Chamber of Commerce Tidewater Builders Association Tidewater Bicycle Association Virginia Beach School Administration Virginia Beach Council of Civic Organizations Green Run Homes Association Resort Area Advisory Commission PUBLIC AGENCIES Several public agencies are responsible for the administration of programs which would be affected by the plans, policies and recommendation of the Virginia Beach Bikeway Plan. In some cases, the implementation of this Plan is the direct charge of these agencies. Funding and other types of assistance may come from State and Federal agencies as well as from local sources. Only through cooperation among these agencies can we anticipate the coordinated implementation of this Plan. As a result, the comments from these agencies provide valuable information for avoiding problems in implementing this Plan. Some of the major public agencies involved in this review process are: DEPARTMENT OF PUBLIC WORKS: The Department of Public Works is responsible for the design, construction and maintenance of most of the bikeways in the City. Three Divisions of this Department (Engineering, Real Estate and Traffic Engineering) have already participated in the development of revised highway typical cross sections to incorporate bikeway paths and lanes in road construction (See Appendix). 42 DEPARTMENT OF PARKS AND RECREATION: The Department of Parks and Recreation is responsible for the city-wide system of parks and recreation centers. This includes promoting the recreational application of bicycling. Through their efforts and cooperation, the city has been able to procure State funding for the construction of the Park Connector Bike Path, which provides access to both Mount Trashmore and Princess Anne Parks. POLICE DEPARTMENT. The Police Department is responsible for the enforcement of traffic regulations and the promotion of highway safety. As a result, their assistance in assessing the safety of bikeway location and design is invaluable. The computerized file of bicycle accidents is used to identify areas of frequent accident occurrences, a factor which was weighted heavily in determining the type and location of bikeway facilities. The Department is also available at the request of schools to conduct lectures and programs on bicycle safety. NAVAL AIR STATIOWOCEANA A U. & ARMY EULSF/FORT STORY: Oceana Naval Air Station and Fort Story Amy Installation are located near population and recreation centers. Each employs both civilians and military personnel There is a need for commuter, shopping and recreational bikeways for employees and their dependents who live on or near the installation. Fort Story is located at Cape Henry, and it surrounds the historic Cape Henry Lighthouse. The installation is an "open" military facility, with virtually free access to the base property. The Bikeway Plan proposes facilities which provide access to both access gates on the base. Oceana Naval Air Station, located southwest of the resort area, is bounded by a number of major roads which connect residential, commercial and industrial areas. The U.S. Navy has agreed to allow the use of right-of-way around the perimeter of the base for bikeway facilities. SOUTHEASTERN VIRGINIA PLANNING DISTRICT COMMISSION: As the designated Metropolitan Planning Agency for this soutbside Hampton Roads area, the Southeastern Virginia Planning District Commission (SVPDC) is responsible for carrying on the continuing, coordinated and comprehensive transportation planning process for the region. In cooperation with the five local jurisdictions (Vir- 43 ginia Beach, Chesapeake, Portsmouth, Suffolk and' Norfolk) and the Virginia Department of Highways and Transportation, SVPDC pre- pares both the Long-range Element and the Transportation Systems Management (Short-Range) Element of the Regional Transportation Needs Study. SVPDC is also responsible for the development of the regional bikeway plan (of which this Plan will be a part). DEPARTMENT OF PLANNING: The Planning Department coordinates the development and implementation of the Bikeway Plan. In addition to acting as liason with other agencies, the Department serves as staff support to the Mayor's Committee, assists in developing project descriptions for inclusion in the Capital Improvement Program, and advises the implementing agencies on the provisions of the Master Street and Highway Plan and the Virginia Beach Bikeway Plan. 2. DEVELOPMENT REVIEW Many of the bikeways proposed in this Plan are located on land which is currently undeveloped. As these areas are developed, the Developers and the City Staff are to work cooperatively to ensure that the provisions of the Bikeway Plan are implemented. The specific methods for implemen- tation are to be determined during the development review process. Upon preparing preliminary subdivision submittals, the Developer or his engineering consultant should be aware of any proposed bikeway alignments in or along the perimeter of the tract to be subdivided. The appropriate dedication or reservation of right-of-way should be specified on the preliminary submittal Information on the appropriate dedication is available from either the Engineering Division of the Department of Public Works or the Department of Planning. In addition, this Plan cannot anticipate the location and design of new neighborhood streets for subdivisions which will be developed during the next several years. Obviously, there are no bikeways planned for these currently undeveloped land tracts. However, once the tract is developed, the need for bikeway facilities will be established. Since any facilities will be tied to the subdivision street system, the location and type of bike facility must be determined concurrently with the establishment of the street system. Specifically, provisions must be made for bikeways in the preliminary subdivision plat and subdivision construction plan. To implement the policy of providing for Bike Routes and Bike Lanes in new subdivisions, the subdivision review process must specify the location of bikeways for inclusion in the subdivision construction plan. Except where otherwise specified in this Plan, Bikeway facilities in subdivisions are to be limited to Bike Routes and Bike Lanes. Bike Routes are to be located on Minor Streets Serving Residential Uses. Bike Lanes are to be located 44 on residential Collector Streets (Pavement widths, right-of-way widths and street types are defined in Section 4.1(m) of the Subdivision Regulations of the City of Virginia Beach). Since Bike Lanes require additional right-of-way and pavement width, they are to be located so that they provide access either to major activity centers (schools, parks, etc.) or to other Bike Paths and Lanes. The exact location and type of Bikeway facilities in developing subdivisions Is to be determined by the Developer and the City's Development Review Staff. 3. FUNDING Funding for bikeway facility construction may be available from a number of separate sources. These sources include: L PWoral Highway Adm tion: Funds allocated through the Federal Highway Administration (FHWA) are administered by the Virginia Department of Highways and Transportation. Funds allocated for roadway construction in the Commonwealth may be used for bikeway construction if the bikeway facility is to be part of a highway construction project. To be eligible for this funding, the bikeway facility must be within the right-of-way limits of the highway. These funds are allocated on a matching basis with the Federal share being 70% and the State and local being the remaining 30%. 2. Virginia Department of Highways and Transportation. The Commonwealth of Virginia through the Virginia Department of Highways and Transportation (VDH&T) will fund bikeway construction concurrently with highway construction projects under the following conditions: A. The Bikeway must be part of an overall plan for commuter bicycle routes. B. The principal use of the facility will be commuter oriented. C. Additional right-of-way necessary for construction on secondary road projects is provided at no cost to the Department. D. In urban areas, the cities and towns will be required to participate in the same proportion as they do for urban highway or street projects. 3. Virginia Commission on Outdoor Recreation: The State Commission on Outdoor Recreation has determined that bikeways providing access to recreational sites are eligible for funding. The Park Connector Bikeway connecting Mount Trashmore and Princess Anne Parks was funded partially with a grant from this Agency. 45 4. City of Virginia Beachs. The City of Virginia Beach has on several occasions.demonstrated that bikeways are a local priority by funding bikeway construction with local revenues. For example, the widening of General Booth Boulevard from Oceana Boulevard to Princess Anne Road was funded with 1980 Referendum Bonds. This project included a Bikeway. In addition, the City has matched grants from other agencies for bikeway construction. Finally, the City financed the construction of the northern portion of the Little Neck Bike Path using Charter Bonds. This project was programmed as part of the Capital Improvement Programming process. 46 APPENDIX d d d d 11 d d i I I I I 1 47 1 DESIGN There is a wide range of facility improvements which can enhance bicycle transportation. Improvements can be simple and involve minimal design consideration (e.g., changing drainage grate inlets) or they can involve a detailed design (e.g., providing a bicycle path). The controlling feature of the design of every bicycle facility is it location (Le., whether it is on the roadway or on an independent alignment). Roadway improvements such as bicycle lanes depend on the roadway's design.' On the other hand, bicycle paths are located on independent alignments; consequently, their design depends on many factors, including the performance capabilities of the bicyclist and the bicycle. Improvements for motor vehicles through appropriate planning and design can enhance bicycle travel and in any event should avoid adverse impacts on bicycling. A community's overall goals for transportation improvements should, whenever possible, include the enhancement of bicycling. Public involvement in the form of public meeting or hearing or bicycle advisory groups is desirable during the design process. Guidelines are presented in this chapter to help design and construct both roadway improvements and separate paths that accommodate the operating characteristics of "bicycles" as defined in this guide. Modifications to facilities (e.g., widths, curve radilt superelevations, etc.) that are necessary to accommodate adult tricycles, bicycle trailers, and other special purpose human powered vehicles and accessories should be made in accordance with expected use, using sound engineering judgement ROADWAYIMPROVEMENTS To varying extents, bicycles will be ridden on all highways where they are permitted. All new highways, except those where bicyclists will be legally prohibited, should be designed and constructed under the assumption that they will be used by bicyclists. Bicycle-safe design practices, as described in this guide, should be followed to avoid the necessity for costly subsequent improvements. Because most highways have not been designed with bicycle travel in mind, there are often many ways in which roadways should be improved to more safely accommodate bicycle traffic. Roadway conditions should be examined and, where necessary, safe drainage grates and railroad crossings, smooth pavements, and signals responsive to bicycles should be provided. In addition, the desirability of adding facilities such as bicycle lanes, bicycle routes, shoulder improvements, and wide curb lanes should be considered. Information on each of the different roadway improvements is contained in this section. 48 Drainage Grates Drainage grate inlets and utility covers are potential problems to bicyclists. When a new roadway is designed, all such grates and covers should be kept out of bicyclists, expected path. On new construction where bicyclists will be permittec4 curb inlets should be used wherever possible to completely eliminate exposure of bicyclists to grate inlets. It is Important that grates and utility covers be adjusted flush with the surface, including after a roadway is resurfaced. Parallel bar drainage grate inlets can trap the front wheel of a bicycle causing loss of steering control and, often, the bar spacing is such that they allow narrow bicycle wheels to drop into the grates, resulting in serious damage to the bicycle wheel and frame and/or injury to the bicyclist. These grates should be replaced with bicycle-safe and hydraulically efficient ones. When this is not immediately possible, consideration should be given to welding steel cross straps or bars perpendicular to the parallel bars to provide a maximum safe opening between straps. This should be considered a temporary correction. While identifying a grate with a pavement marking, as indicated in the MUTCD, would be acceptable in most situations, parallel bar grate inlets deserve special attention. Because of the serious consequences of a bicyclist missing the pavement marking in the dark or being forced over such a grate inlet by other traffic, these grates should be physically corrected, as described above, as soon as practicable after they are identifiecl Railroad Cr=Wngs Railroad-highway grade crossings should ideally be at a right angle to the rails. The greater the crossing deviates from this ideal crossing angle, the greater is the potential for a bieyclist's front wheel to be trapped in the nangeway causing loss of steering control. It is also important that the roadway approach be at the same elevation as the rails. Consideration should be given to the materials of the crossing surface and to the flangeway depth and width. If the crossing angle is less than approximately 45 degrees, consideration should be given to widening the outside lane, shoulder, or bicycle lane to allow bicyclists adequate room to cross the tracks at a right angle. Where this is not possible, commercially available compressible nangeway fillers can enhance bicyclist safety. In some cases, abandoned tracks can be removed. Warning signs and pavement markings should be installed in accordance with the MUTCD. 49 Pgivements Pavement surface irregularities can do more than cause an unpleasant ride. Gaps between pavement @ or drop-offs at overlays parallel to the direction of travel can trap a bicycle wheel and cause loss of control; holes and bumps can cause bicyclists to swerve into the path of motor vehicle traffic. Thus, to the extent practicable, pavement surfaces should be free of irregularities and the edge of the pavement fill joints, adjust utility covers or, in extreme cases, overlay the pavement to make it suitable for bicycling. Traffic @ol Devices At intersections where bicycle traffic exists or is anticipated, bicycles should be considered in the timing of the traffic signal cycle, as well as the traffic detection device. Normally, a bicyclist can cross an intersection under the same signal phasing arrangement as motor vehicles: However, on multi-lane streets special consideration should be given to ensure that short clearance intervals are not used. if necessary, an all-red clearance interval may be used. To check the clearance interva4 a bicyclist's speed of 10 mph (16m/h) and a perception/reaction/braking time of 2.5 second.% should be used. Detectors for traffic-actuated signals should be sensitive to bicycles and should be located in the bicyclist's expected patn including left turn lanes. Where programmed visibility signal heads are used, they should be checked to ensure that they are visible to bicyclists who are properly positioned on the road. The MUTCD should be consulted for guidance on signs and pavement markings. Where bicyclists are expected to use different routings than motorists, directional signing should be used to confirm to bicyclists that the special routing leads to their destination. Woulders Wide curb lanes and bicycle lanes are usually preferred over shoulders for use by bicyclists. However, if it is Intended that bicyclists ride on shoulders, smooth paved shoulder surfaces must be provided. Pavement edge lines supplement surface texture in delineating the shoulder from the motor vehicle lanes. Rumble strips can be a deterrent to bicycling on shoulders and their benefits should be weighed against the probability that bicyclists will ride in the motor vehicle lanes to avoid them. Shoulder width should be a minimum of 4 feet (1.2m) when intended to accommodate bicycle travel. Roads with shoulders less than 4 feet (1.2m) wide normally should not be signed as bikeways. If motor vehicle speeds exceed 35 mph (55m/h), if the percentage of trucks, buses, and recreational vehicles is high, or if static obstructions exist at the right side, then additional width is desirable. 50 Adding or improving shoulders can often be the best way to accommodate bicyclists in rural areas, and they are also a benefit to motor vehicle traffic. Where funding is limited, adding or improving shoulders on uphill sections first will give slow moving bicyclists needed maneuvering space and decrease conflicts with faster moving motor vehicle traffic. Wide Curb Lanes On highway sections without bicycle lanes, a right lane wider than 12 feet (3.7m) can better accommodate both bicycles and motor vehicles in the same lane and thus is beneficial to both bicyclists and motorists. In many cases where there is a wide curb lane, motorists will not need to change lanes to pass a bicyclist. Also, more maneuvering room is provided when drivers are exiting from driveways or in areas with limited sight distance. in general, a lane width of 14 feet (4.3m) of usable pavement width is desired. Usable pavement width would normally be from curb face to lane stripe, or from edge line to lane stripe, but adjustments need to be made for drainage grates, parking, and longitudinal ridges between pavement and gutter sections. Widths greater than 14 feet (4.3m) can encourage the undesirable operation of two motor vehicles in one lane, especially in urban areas, and consideration should be given to striping as a bicycle lane when wider widths exist. ENcycle Routes It may be advantageous to sign some urban and rural roadways as bicycle routes. When providing continuity to other bicycle facilities, a bicycle route can be relatively short. However, a bicycle touring route can be quite long. For long bicycles routes. a standard bicycle route marker with a numerical designation in accordance with Part IX of the MUTCD can be used in place of a bicycle route sign. The number may correspond to a parallel highways indicating the route is a preferred alternate route for bicyclists. It is often desirable to use supplemental plaques with bicycle route signs or markers to furnish additional information, such as direction changes in the route and intermediate range distance and destination information. Bicycle route signing. should not end at a barrier. Information directing the bicyclist around the barrier should be provided. Overall, the decision whether to provide a bicycle route should be based on the advisability of encouraging bicycle use on a particular road, instead of on parallel and adjacent highways. The roadway width, along with factors such as the volume, speed, and type of traffic; parking conditions; grade; and sight distance should be considered when determining the feasibility of a bicycle route. Generally, bicycle traffic cannot be diverted to a less direct alternate route unless the favorable factors outweigh the inconvenience to the bicyclist. Roadway improvements, such as safe drainage grates, railroad crossings, smooth 51 pavements, maintenance schedules, and signals responsive to bicycles should always be considered before a roadway is identified as a bicycle route. Further guidance on signing bicycle routes is provided in the MUTCD. Bicycle Lanes Bicycle lanes can be considered when it is desirable to delineate available road space for preferential use by bicyclists and motorists, and to provide for more predictable movements by each. Bicycle lane markings can increase a bicyclist's confidence in motorists not straying into his/her path of travel. Likewise, passing motorists are less likely to swerve to the left out of their lane to avoid bicyclists on their right. Bicycle lanes should always be one-way facilities and carry traffic in the same direction as adjacent motor vehicle traffic. Two-way bicycle lanes on one side of the roadway are unacceptable because they promote riding against the now of motor vehicle traffic. Wrong-way riding is a major cause of bicycle accidents and violates the Rules of the Road stated in the Uniform Vehicle Code. Bicycle lanes on one-way streets should be on the right side of the street, except in areas where a bicycle lane on the left will decrease the number of conflicts (e.g., those caused by heavy bus traffic). Under ideal conditions, minimum bicycle lane width is 4 feet (1.2m). However, certain edge conditions dictate additional desirable bicycle lane width. The minimum bicycle lane width for such locations is 5 feet (1.5m). Bicycle lanes should always be placed between the parking lane and the motor vehicle lanes. Bicycle lanes between the curb and parking lane create hazards for bicyclists from opening car doors and poor visibility at intersections and driveways, and they prohibit bicyclists from making left turns; therefore this placement should never be considered. Where parking is permitted but a parking lane is not provided, the combination lane, intended for both motor vehicle parking and bicycle use, should be a minimum of 12 feet (3.7m) wide. However, If it is like the combination lane will be used as an additional motor vehicle lanes it is preferable to designate separate parking and bicycle lanes as shown in Figure l(a). In both instances, if parking volume is substantial or turnover is high, an additional 1 or 2 feet (0.3 or 0.6m) of width is desirable for safe bicycle operation. Bicyclists do not generally ride near a curb because of the possibility of debris, of hitting a pedal on the curb, of an uneven longitudinal joint, or of a steeper cross-slope. Bicycle lanes in such locations should have a minimum width of 5 feet (1.5m) from the curb face. if the longitudinal joint between the gutter pan and the roadway surface is uneven and falls within 5 feet (1.5m) of the curb face, a minimum of 4 feet (1.2m) should be provided between the joint and the motor vehicle lanes. 52 Bicycle lanes may have a minimm width of 4 feet (1.2m), where the shoulder can provide additional maneuvering widtt4 A width of 5 feet (1.5m) or greater is preferable; additional widths are desirable where substantial truck traffic is present, where prevailing winds are a factor, on grades, or where motor vehicle speeds exceed 35 mph (55km/h). Bicycle lanes tend to complicate both bicycle and motor vehicle turning movements at intersections. Beemse they encourage bicyclists to keep to the right and motorists to keep to the left, both operators are somewhat discouraged from merging In advance of turns. Thus, some bicyclists will begin left turns from the right-dft bicycle lane and some motorists will begin right turns from the lane to the left of the bicycle lane. Both maneuvers are contrary to established Rules of the Road and result in conflicts. At intersections, bicyclists pr ing straight through and motorists turning right must cross paths. Striping and signing configurations which encourage these crossings in a@nce of the intersection, In a merging fashion, are generally preferable to those that force the crossing in the immediate vicinity of the internnion. To a lesser exteni4 the same is true for left-tuming bicyclists; however, in this maneuver, most vehicle codes allow the bicyclist the option of making either a "vehicular style" left turn (where the bicyclist merges leftward to the same lane used for motor vehicle left turns) or a *pedestrian style" left turn (where the bicyclist proceeds straight throvo the intersection, turns left at the far sides then proceeds across the intersection again on the cross street). Where there are numerous bi a separate turning lane, as indicated in Part IX of the MUTCD, sh=M be considered. The design of bicycle lanes should also include approwate signing at intersections to reduce the number of conflicts. General guidance for pavement marking of bicycle lanes is contained in the MUTCD. Ade4uate pavement surface, bicycle-safe grate Inlets, safe railroad crossings, and traffic signals mponsive to bicycles should always be provided on roadways where bi@e lanes are being designated. Raised pavement markings and raised barriers can cause steering difficulties for bicyclists and should not be used to delineate bicycle lanes. Bl@E PATHS Bicycle paths are facilities on exclusive rigbt-of-way and with minimal cross now by motor vehicles. Bicycle paths can serve a variety of purposes. They can provide a eommuting bicyclist with a shortcut through a residential neighbwhood (e.g, a connection between two cul-de-sac streets). Located in a park, they can provide an enjoyable recreational opportunity. Bi@ paths can be located along abandoned railroad rights-of-way, the banks of river@ and other similar areas. Bicycle paths can also provide @le access to areas that are otherwise served only by limited access highways closed to bicycles. Appropriate locations can be identified during the planning process. 53 Bicycle paths should be thought of as extensions of the highway system exclusive or preferential use of bicycles in that are intended for the .nte ad for the exclusive or much the a reeways are I ar@ any similarities between ame way as f e of motor vehiele@ Th -9., in preferential us paths aV those for highways (a design criteria for bicycle - quirementst signingo and ment determining horizontal aitgn . horizontal and vertical the other hand 51 re) are dictated by markings).

The vertical clearance to obstructions should be a minimum of 8 feet (2.4m). However, vertical clearance may need to be greater to permit passage of maintenance vehicles and, in underpasses and tunnels, a clearance of 10 feet (3m) is desirable for adequate vertical sight distance.
