ITEM # 41956 John Herzke, City Engineer, advised The Public Works Specifications and Standards Manual was adopted by City Council on June 14, 1994, with the provision that all amendments shall be forwarded to City Council each year for adoption. The amendments proposed in the City Council Agenda include a compilation of proposed revisions to The Public Works Specifications and Standards Manual These revisions address items requiring clarification and supplemental information identified during the last year associated with the use of the manual This has been compiled by City staff with input from and review by area consultants, Tidewater Builders ,4ssociation and outside agencies to improve the content and clarity of the manual. Chapter 1: Section 1.7 has been added to reflect Public Works' role in development review and construction which is handled by the Planning Department Chapter 2: Various sections of this chapter have been reviewed to clarify language and intent, as well as to update materials specifications including storm drainage pipes, traffic signs and sign poles, and other traffic control services. A standard for recycled plastic decorative traffic sign posts for residential streets is added to complement a new drawing for the same in Appendix D. Chapter 3: Several sections dealing with traffic control guidelines, entrances onto roadways and roadway geometric design standards were taken out of Chapter 6, updated and inserted into Chapter 3. These sections previously shown in Chapter 6 are to be deleted and are crossed out in the chapter because these sections more appropriately belong in Chapter 3. Other sections involving engineering design guidelines, technical requirements for "As-Built" record drawings, and minimum shouMer wider requirements were updated. Section 3. 7.14 was revised to require developments to install, at a minimum, adequate pavement width, an eight-foot wide earth and/or gravel shouMer, plus a relocated drainage ditch along existing road frontages where standard curb, gutter, sidewalk and other urban improvements are not appropriate due to the rural nature of the area or the character and specifics of the development. Chapter 4: Only one page was revised to clarify and to give more flexibility to soils testing and subsequent pavement design options. Chapter 6: Sections of Chapter 6 were revised to bring curb cut ramps up to date with the latest VDOT and ADA (Americans with Disabilities Act) requirements. As mentioned in Chapter 3 sections dealing with traffic control, entrances, and geometrics were deleted from this Chapter 6, updated and inserted into Chapter 3. Renumbering of the remaining sections' titles were necessary. Chapter I0: Wording was added to clarify the requirement that City roadway projects as well as private development must tie to the State Plane Coordinate System. Chapter 11: Clarification was given to sections dealing with the requirements, procedures, and processes .for "As-Built" survey drawings and plans for the City's records. April L 1997 -3- CITY MANAGER'S BRIEFING PUBLIC WORKS SPECIFICATIONS MANUAL AMENDMENTS ITEM # 41956 (Continued) Chapter 12: Sections 12.4 and 12.5 were revised and expanded to protect the City's interest on the standard to be used for bulkheads, revetments, or other shoreline hardening structures along the oceanfront and the bayfront. A correction was made to refer to Section 5B of the Site Plan Ordinance for floodplain issues. Chapter 15: A correction was made to show that Civil Inspections Bureau is no longer in Public Works. Chapter 16: Sections were revised to update traffic control standards. The City is attempting to have emergency vehicle pre-emption equipment installed in all new traffic signals and to retrofit existing signals in the future, as resources permit. APPENDIX B: Several drawings in Appendix B, dealing with standard storm drainage structures, are included in the package. Minor revisions were made to increase structural strength and to make the drawings more flexible to take advantage of available standard pre-cast concrete structures. Also, new drawings for standard shallow structures were included to assist in reducing design costs for special structures used with many projects. APPENDIX C: Drawing C-7, CG-12 Curb Ramp was revised to bring it into compliance with City policy as well as state and federal ADA regulations. The standard City Wakefield Bulkhead drawing is added to Appendix C along with a new drawing for concrete paver units when used specifically for sidewalks and pedestrian crosswalks within the roadway pavement. APPENDIX D: New drawings were added providing standard details for a recycled plastic decorative traffic sign post, and the telescoping steel traffic sign posts, which are referred to in Chapter 2. Other minor changes to the City standard median nose and entrance locations were made to improve safety. APPENDIX E: The standard traffic engineering general notes were updated. April 1, 1997 -4- CITY MANAGER'S BRIEFING WELFARE REFORM 11:15 A.M. ITEM # 41957 Daniel M. Stone, Director - Social Services, advised in July 1995, Welfare Reform became a reality in Virginia. At that time the General Assembly approved the Virginia Independence Program (VIP) on a state-wide basis. A variety of components were included in VIP, including a work component which is called the I/irginia Initiative for Employment not Welfare (}rlEW). VIEW began a phased-in program with the Culpepper Economic Development District being the first to implement the work component. Since that time, four additional Economic Development Districts have begun participation in the program. The final implementation of VIEW will be accelerated throughout the State. Virginia Beach and the other Hampton Roads cities will initiate VIEW in October 1997. The Virginia Beach Department of Social Services has already implemented those components of the Virginia Independence Program (PIP) which affect all Temporary Assistance to Needy Families (TANF) recipients in our City and throughout the State. The VIP components have already increased the volume of work for staff. Nancy Hinch, Co- ordinator for Welfare Reform, and Pat Warren, Division Chief- Financial Services, assisted in the presentation. Components of the VIP program mandated throughout the Commonwealth are: Learnfare requires children receiving TANF to attend school. Mothers who do not keep their children in school lose a part of their benefits when the truant child is removed from the grant. A child born ten months after the mother begins receiving TANF will not be included in the TANF grant. This child will receive all of the child support collected from the father and will also receive Food Stamps and Medicaid. Unless married, teen parents under the age of 18 are required to live with a parent or person acting as a parent in order to receive TANF for their children. Parents receiving TANF must have their children immunized. If this is not done, the benefits are reduced for each child not immunized. ,4 parent is required to cooperate with the Division of Child Support Enforcement in securing support from the absent parent(s) of children receiving TANF. If the custodial parent is uncooperative, the amount of benefits are reduced and the case may ultimately be closed. Two-parent families may now receive TANF for unemployed parents for as long as their eligibility continues to exist. This assistance is intended for two-parent families when one parent is either unemployed or underemployevL The Diversion Assistance Program provides assistance to otherwise eligible families totaling up to 120 days of TANF assistance in a lump sum to meet a one time emergency. This assistance is limited to one time in a six month period and requires that the family not apply for TANF benefits for up to 160 days after the receipt. After implementation of VIEW in October 1997, these additional components will be mandatory: TANF recipients must sign an Agreement of Personal Responsibility at which time their two year time limit for the receipt of benefits will begin. Mothers whose children are 18 months or older will be required to participate in the work component. April L 1997 -5- CITY MANAGER'S BRIEFING WELFARE REFORM ITEM # 4195 7 (Continued} Recipients must participate in a work component sdthin 90 days of signing the Agreement of Personal Responsibility. Higher income disregards will be available to employed customers. They will be allowed to keep their income and TANF grant totaling up to 150% of the Federal poverty level. Recipients who are required to work may own a car worth up to $7,S00.00 Recipients will be allowed a savings account of up to $5,000.00 with which to start a business. Recipients may not reapply for assistance for two years following the termination of their assistance due to the two year time limit. Hampton Roads is the last area to phase-in a work component of welfare refornr Hampton Roads constitutes 30% of all welfare recipients in Virginia. PUBLIC ASSISTANCE IN VIRGINIA BEACH AS OF FEBRUARY 1997 Virginia Beach has a total of 2,262 TANF families. 2,162 families are headed by single female parents. 3,687 children receive assistance 1,317 adults receive assistance. 49% of the adults have completed high school. 220 families are headed by mothers under 21 10 families are headed by mothers under 18 The average length of stay on assistance is about 18 months. The family is constituted as an adult plus one or more minors living together.

Pat Warren advised there are approximately 600 cases in V'trginia Beach of senior citizens who are legally in the United States, but have not become citizens. 200 cases do not qualify.

Brown advised proceeds from the fair will enhance educational opportunities for youngsters in the region through the provision of scholarships. The State Fair annually contributes thousands of dollars in educational scholarships to Virginia's youth by providing wholesome, competitive programs.

Council Lady Henley distributed copies of the correspondence to City Counci~ which is hereby made a part of the record. The Cartwright's requested assistance in either obtaining the removal of the Princess Anne Road site designation across these properties, or obtaining the City's approval to purchase this property at existing fair market value prices. Council Lady Henley did not believe this improvement of Princess Anne Road wouM be done anytime in the near future; however, it is hard to say whenever the community might desire this improvement. The City Staff does not recommend a street closure. ITEM # 4196O Vice Mayor Sessoms inquired relative the cost of the day shelter.

Revised 3/97 Table of Contents Page xxxv Public Works Specifications and Standards (This page intentionally left blank) Page xxxvi Table of Contents Revised 3/97 Public Works Specifications and Standards FORWARD This manual replaces all previous Department of Public Works Specifications_ and Standards, "Engineering Standards" , and establishes new Department of Public Works Engineering Division Specifications and Standards for development in the City of Virginia Beach, Virginia. These specifications and standards are intended for the use in the design and preparation of contract documents for all work in the City of Virginia Beach, Virginia Ordinances, and all contracts awarded by the Department of Public Works, City of Virginia Beach, Virginia. Their authority is established by the adopted resolutions of the City of Virginia Beach Council and the ordinances of the City. " "will " "must " "should," "may," and The use of the words "shall, , , "can" within these specifications and standards is meant to emphasize directions which will ensure the appropriate intended purpose is understood. To clarify the meanings intended in this manual by the use of these words, the following definitions shall apply: SHALL. WILL. OR MUST A mandatory_ condition. Where certain design criterion is described in a procedure or in the design of public improvements, it is mandatory that this condition be met. An~&~ condition. Where the word "should" is used, it is considered to be advisable usage, recommended but not mandatory at the review engineer's discretion. ~AY OR CAN A permissive condition. Design or application for good engineering practice but is optional at the review engineer's discretion. Questions or comments concerning this manual or the specifications and standards contained within, should be directed to the City of Virginia Beach, Department of Public Works, City Engineer's Office. Revised 3/97 Table of Contents Page xxxvii Public Works Specifications and Standards (This page intentionally left blank) Page xxxviii Table of Contents Revised 3/97 Public Works Specifications and Standards CHAPTER 1 INTRODUCTION SECTION 1.0 Intent This manual provides the Public Works design and construction Specifications and Standards for City right-of-ways, easements, and City owned property as well as private property development. 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. The following manuals and publications or latest editions are hereby adopted, and made an integral part of these specifications and standards: Virginia Department Specifications (1994) of Transportation Road and Bridge Revised 3/97 Introduction Page 1 - 1 Public Works Specifications and Standards If any errors are found in the Virginia Department of Transportation Road and Brid~e Specifications (1994); then the Virginia Department of Transportation Road ~nd Bridge Standards (1993) shall apply, or Public Works Engineering shall be consulted for further information and guidance.

Page 1 - 6 Introduction Revised 3/97 Public Works Specifications and Standards Section 1.7 Public Works Role in Private Development Review and constructi0~ I. General Topics, issues and details covering the role of Public Works in private development review for Planning Development Services Center (DSC) are listed and discussed below. Questions on these standards and this Manual in general are to be directed to the DSC first in order to ensure proper coordinating of all aspects of a development. A. Development Review: The City of Virginia Beach supports the common well being and promotes economic growth for the betterment of the citizens of the City. The unique geographic, physical, and cultural attributes of Virginia Beach offer opportunities to expand its benefits to more people and citizens. In this regard, it is the desire of the City Council to encourage thoughtful and beneficial development. Commercial, agricultural, and residential development, when in conformance with the various City, state, and federal codes and regulations, is encouraged. Towards this end, and in an effort to expedite the benefits of such development, the City has centralized the development review process. The Development Services Center (DSC) in the Planning Department, has been established as the focal point for all activities related to the private utilization and development of the land resources within the City limits. The DSC provides guidance and support to developers in obtaining City approval for proposed developments. · The DSC follows the City Council's direction as reflected in ordinances and resolutions. This direction is captured in the City Code, particularly in Appendix A (Zoning Ordinance), Appendix B (Subdivision Regulations), Appendix C (Site Plan Ordinance), Appendix D (Storm Water Management), and Appendixes E, F, G, and H. · The DSC is both the orchestrator and reviewer, consolidating the sometimes complex and extensive review process, insuring timely and meaningful responses while protecting the City's interests at the same time. The DSC, staffed internally with expertise to perform most development/site plan reviews, may call upon supporting departments, including Public Works, for more in-depth consultational advice when difficult, complex, or Revised 3/97 Introduction Page 1 - 7 Public Works Specifications and Standards Be unusual issues arise. The supporting departments provide assistance as requested, in a timely manner to enable the DSC to quickly respond to citizen/developer inquiries and requests. · The Civil Inspections Bureau within the Planning Department is the inspections office that handles inspection and construction coordination of private development projects. They work closely with the engineers and other review agencies in the Planning Department to enforce requirements shown on approved development plans and to ensure good construction practices are followed. Engineering Center of Excellence The Public Works Department, as the City's Engineering "Center of Excellence" provides engineering support to all City departments. Through the Specifications and Standards Manual approved by City Council, the engineering criteria for City funded Projects as well as private development projects is clearly established. The manual forms the basis for any development work which will be provided/dedicated to the City or which works in conjunction with City systems such as storm water systems for example. The standards and the commensurate requirements they place on developers are published to provide an easily obtainable and consistent baseline against which all work will be measured both in the plan review and the inspection process. · In addition to the documented manual, the Public Works Department has a staff of more experienced civil engineers, traffic specialists, surveyors, real estate, and mapping specialists capable of providing consultation services to the DSC for development review when the need arises. In addition, those areas where the skills or capabilities are absent from the DSC (i.e. traffic engineering, surveying, mapping, and real estate), Public Works acts as the consultant for the DSC, providing comments for inclusion in overall DSC development reviews. Additionally, when a DSC engineer seeks a "second opinion" or "consultation" for an unusual or a technically complex review, Public Works Engineering provides such additional professional capability to the DSC's Civil Engineers. However, day to day reviews, inspections, complaints, and problem solving are handled by the engineers and project managers in the DSC. Page 1 - 8 Introduction Revised 3/97 Public Works Specifications and Standards II. C-. · Proposed Public Works Specifications and Standards Manual changes, new engineering or city-wide engineering information is distributed to all area consultants via the Bimonthly City/Consultant meetings hosted by Public Works Engineering. The purpose of such meetings is to encourage a dialogue between the City and consultants/designers relating to engineering issues. Overall City Concerns The review actions performed by the DSC, while detailed, are all intended to protect City and taxpayer resources. They ensure that any infrastructure constructed, which the City will subsequently accept or maintain, or which protects other citizens, conforms to City standards. · Considering the City Council's stated desire to encourage judicious development, the review process must be responsive to developers' needs to facilitate their construction thereby adding new residents, businesses, or organizations to the tax rolls. This balance of protecting the City while encouraging development is met within the DSC. Difficult as it may be, decisions are made daily to ensure measured progress is achieved toward an improving and growing Virginia Beach. public Works Support kO Planning/DSC for Qevelop~ent Review A. Responsibilities: The Public Works Department is responsible for roads, storm water systems, trash collection, and several other aspects of City infrastructure and service related to engineering. In this role, it is also responsible for the maintenance and upkeep of most infrastructure dedicated to the City by developers (i.e. roads, storm water management facilities, etc.) with the exception of sanitary sewer and potable water (drinking water) facilities. · Additionally, the Public Works Department has engineers with a wide assortment of skills to support all City departments when needed. It is the center for solving unusual or complex engineering problems which generally exceed other staffs' engineering experience or capabilities. This "Center of Excellence" concept translates into providing consulting services to others within the City as needed and in a timely manner. Revised 3/97 Introduction Page 1 - 9 Public Works Specifications and Standards Be · Finally, the Public Works department is responsible for the "Public Works Specifications and Standards" Manual. This Manual publishes the City's engineering requirements in a single document, available to all. Since this manual defines the City engineering standards, any variances requested by developers from the Manual's provisions are investigated, evaluated, and processed with a recommendation by the DSC and forwarded to Public Works, through the Engineering Division for final evaluation and recommendation. Waivers of the manual's engineering requirements may be granted by the Director of Public Works. New engineering methods/requirements and other City-wide information planned for inclusion in the manual is distributed to all area consultants via the Bimonthly City/Consultant meetings, hosted by Public Works/Engineering. This meeting serves as a forum to exchange ideas and involve the consultant and contracting community in the City's engineering and standards process. Feedback from Planning Departments', DSC and Civil Inspections, Public Works Operations, and other City agencies is passed on to the consultant and contracting community and incorporated into the Public Works Specifications and Standards Manual if appropriate. Feedback that is received from consultants and contractors at the Bimonthly meetings is also addressed and passed on to the appropriate City agencies. Public Works Engineering also coordinates and participates with the overall region's local governments, Public Works, and Public Utility Departments' via the Hampton Roads Planning District Commission's (HRPDC) Municipal Standards Subcommittee for engineering standards and related issues. Unique Areas: The Public Works Department contains several unique areas of expertise which are not available in the DSC or other departments. While the DSC and the Planning Department has planners, inspectors, engineers, etc., it does not have an internal capability in the real estate, surveying, mapping, and traffic engineering areas. Those capabilities remain exclusively in the Public Works Department. · The Public Works Operations Division maintains a customer service office for receiving complaints and inquiries involving drainage, roads, and other public infrastructure except water and sanitary sewer. Those which are development related are passed on to Civil Inspections and the Development Page 1 - 10 Introduction Revised 3/97 Public Works Specifications and Standards Services Center, when the complaints are associated with private development. C.., Qperator of Dedicated Infrastructure: The Public Works Department, through the Specifications and Standards Manual, guides the developer who constructs infrastructure for dedication to the City (as part of their project). Public Works Operations then assumes the responsibility for the operation and maintenance of most of the infrastructure for the City. Exceptions such as water, sewer, buildings, and parks are maintained by other City Departments. By review of planned construction, and participation in various inspections, especially the final inspection, Public Works personnel gain first hand knowledge and feedback about the infrastructure the City will accept and maintain. III. The Review Process A. The DSC: Ail development activities for the City start and end with the DSC. As noted above, the DSC orchestrates the City review of proposals, development plans, etc. to ensure the City's (and citizen's) interests are protected. In the early stages of a proposed development, the developer may request a pre-submittal meeting between his consultant and the City reviewers. This informal meeting, although not required, provides necessary background, information,and assistance for both the designer/consultant and City reviewers so the developer's submittals are correct and City reviews are completed quickly and efficiently. · The resultant preliminary subdivision, when received by the DSC, is distributed to internal DSC reviewers as well as Public Works Traffic Engineering and Mapping. Upon completion of the reviews, the approval (or comments identifying needed correction) is returned to the developer by the DSC. A copy of that response is provided by the DSC to Public Works Traffic Engineering, Mapping and Real Estate so they can track ongoing actions. · If the development is not a subdivision and only requires a site plan submittal, the DSC, upon receipt, distributes it to Public Works Traffic Engineering. Engineers from Public Works Engineering Storm Water Bureau or the Design Revised 3/97 Introduction Page 1 - 11 Public Works Specifications and Standards · . · section are asked to participate if an unusual storm water issue arises. The Storm Water Bureau also assists with storm water equivalent residential unit calculations, if needed due to unusual site or drainage characteristics. When the preliminary subdivision is approved, the subdivision construction plan (which normally includes the Storm Water Management Plan and Erosion and Sediment Control Plan) is prepared and submitted to the DSC for approval. Again, the DSC quickly distributes the submittal for internal and external review. Within Public Works, only Traffic Engineering reviews this submittal. If, however, the Planning DSC or Planning Waterfront Operations identifies a concern for an unusual or complex issue in the waterfront, storm water, or other technical area, they may request comments from Public Works Engineering or Public Works Beach Management. Reviews are completed within 21 days and approval or comments are provided to the developer via the DSC. Once the Erosion and Sediment Control Plan is approved (usually a component of the Storm Water Management plan, as a section of the subdivision construction or site plans), bonds are posted and an erosion and sediment control permit is issued. These reviews and subsequent procedures are handled within the DSC. Public Works is not normally involved in these actions. After receipt of this permit, land disturbing activities may begin. If full construction or site plan approval and proper permits are obtained, construction of the proposed public and private infrastructure may commence. During construction, City Civil Inspectors from the Planning Department periodically review progress, ensuring that all phases of the work comply with approved plans, with good construction practices, as well as with federal, state, and City Standards. Note: this is not an inspection of every aspect of construction, but rather one to ensure overall compliance with the approved plans to protect the City's interests. Quality control inspections continue throughout a development project during all phases of construction. Usually near the completion of construction (although it could be earlier if certain performance bonds are posted), the developer submits his final plat, deeds, bonds, agreements, etc. for review and recordation. The DSC simultaneously reviews these documents with the Page 1 - 12 Introduction Revised 3/97 Public Works Specifications and Standards Be City Attorney and Public Works Surveying Bureau and the Real Estate Bureau. When found complete, the documents are signed and recorded. · Record drawings are provided to the DSC when construction is complete. The DSC distributes them for 1) recording within the City's mapping system and 2) use by the City operators who are charged with maintaining the improvements dedicated to the City. In addition, the Certificate of Completion, which allows the release of all but the defect bond, is coordinated and signed by the DSC after the inspecting agencies have signed off on their areas of responsibility. · In the interest of improving the quality of development and/or reducing costs, the DSC and/or consulting engineers may work with the Public Works staffs to develop new standards and specifications for general or specific use. New and innovative methods of construction or design may be tested and evaluated with development projects for later inclusion in the Public Works Specification and Standards Manual. Review, as noted earlier, of such manual changes are coordinated by Public Works Engineering. Public. Works Role The Public Works role, as generally defined above is accomplished in several phases: When requested by the DSC, Public Works engineers participate in the pre-submittal meetings. This provides the engineer-to-engineer information so that those aspects of a development planned for dedication to the City are based on accurate, consistent, and acceptable data. Not surprisingly, the more detailed the discussions at this stage, the fewer the review comments later in the process. The Public Works Specifications and Standards Manual establishes the baseline requirements for construction to be dedicated to the City. · Upon receipt of the preliminary subdivision plan from the DSC, both Mapping and Traffic Engineering review the submittal simultaneously. Mapping assigns the preliminary GPIN corresponding to the area for identification. Traffic Engineering fully reviews all roadway requirements and designs, traffic control, streetlights, and signals planned or required for dedication to the City. In addition to these reviews, if the DSC has noted any other areas of concern, such as water body impacts, special storm water problems, or if a survey review is called for, they will also forward a request for Revised 3/97 Introduction Page 1 - 13~ Public Works Specifications and Standards · · assistance and advice directly to Beach Management, Engineering, Operations, or the Survey Bureau. Those sections of Public Works receiving a request from the DSC will complete the requested review and provide comments within 21 days or as required by the DSC. As the City's engineering "Center of Excellence", Public Works Engineering will "consult" and provide requested advice, review, and information on any areas beyond the DSC engineer's capabilities when requested. After development or during infrastructure construction along with bonding of the infrastructure to protect the City, the final plats and legal documents are submitted to the DSC for approval and recordation. The DSC forwards the plats to the City Surveyor and the Mapping Bureau in Public Works for review of the City improvements to ensure they are correctly reflected and that the proper state plane coordinate system has been used. Mapping reviews the final plat to insure that GPINs are correct and to note any lot or boundary changes. The City Surveyor's review is usually complete in 7 days permitting prompt plat recordation. Similarly, the legal documents are forwarded to Real Estate if any City real estate action is required. If any such action has been requested of Real Estate (and the need is diminishing since most dedications are now being shown on plats) it will be completed and forwarded to the DSC and City Attorney for further action. When improvements are to be provided to the City, the Planning Department's Civil Inspector will notify the Public Works Operation's Planner/Estimators to assist with the final inspections. Public Works Planner/Estimators will participate when practicable. While not the final authority in the inspection, the Public Works Planner/Estimator is present when requested to assist in ensuring that improvements comply with City standards. In addition, he is there to view the facilities to be provided to the City. Final inspections will not be delayed due to the non- availability of Public Works Operations' Planner/Estimators. The Public Works' Mapping Bureau participates in final acceptance of infrastructure and receipt of copies of record drawings. This will ensure that the necessary information such as edge of roadways, new right-of-ways, underground pipes, public buildings, and parking lots, etc. are recorded for Page 1 - 14 Introduction Revised 3/97 Public Works Specifications and Standards · future Public Works maintenance for those facilities being dedicated to the City. Proper recording in the Public Works Maintenance Management System is essential to allow follow-up on City inspection and maintenance. In cases where the Planner/Estimator cannot accompany the Planning Department's Civil Inspector to the job site, then the Civil Inspector will ensure that a copy of his report is forwarded to the Public Works Operations' Planner/Estimator. When all work has been completed, record drawings ("as-builts") are provided to the DSC by the developer. The DSC forwards the record drawings to the Public Works Mapping and Survey Bureaus. Mapping records the general improvements in the GIS showing infrastructure to be owned by the City and well as general improvements shown on site plans that are privately owned. The Survey Bureau performs field surveys to check the completion and accuracy of all storm drainage, sanitary sewer systems, grades, monumentation and right-of-ways. Acceptance by the City Surveyor is required prior to bond release. · · Notification by the Planning Department is given to the Public Works Operations Management Bureau to update the maintenance files and commence maintenance on any new City storm drainage facilities and infrastructure to be owned by the City. If storm water facility improvements have been dedicated, if easements are provided to the City or if private water quality facilities drain into the City systems, the Storm Water Section of Engineering also receives the appropriate record drawings to update their data base. Since this is only the documentation phase for storm water facilities, no report is returned to the DSC upon completion of this updating of the storm water infrastructure data base. The Certificate of Completion documents the completion of all work for bond release on subdivision construction. The Public Works Surveys Bureau and the Real Estate Bureau sign off as needed. After all aspects of the Certificate of Completion have been fulfilled, the certificate is signed by the DSC, the performance bond is released and a defect bond is posted completing the subdivision development. Revised 3/97 Introduction Page 1 - 15 Public Works Specifications and Standards IV. a. m~ C. Traffic Engineering Working Meetings!Pre-submittal Me_eting: When requested by the developer or his consultant, either directly or indirectly through the DSC, working meetings may be held with Traffic Engineering. The purpose of the working or pre- submittal meetings are to establish a dialogue and to provide an exchange of information between the design consultant and the City staff to enable the developer to more efficiently prepare a correct development plan. The goal of such meetings is to provide the design engineer or consultant with the basis to prepare submittals that comply with City Standards, good engineering practices, and good construction practices. All meetings are informal, but usually documented, and are intended to help the participants. As a by-product of such meetings, the City's participating Traffic Engineer will gain an insight into the design concept, identify appropriate requirements, and be able to more quickly review the submittal when received. Preliminary Plat: upon receipt of the preliminary plat from the DSC, Traffic Engineering looks for any possible impacts the proposed development will have on neighboring areas and roads, and the solutions proposed to minimize them. Access, safety and other traffic related concerns both during and after construction are addressed at this stage. Comments are forwarded to the DSC within 21 days. Site Plan: Site plan submittals received from the DSC are acted upon within 21 days. Review items center on compliance with the Public Works Specification and Standards as well as correction to the earlier submittals, if applicable. Specifically, Traffic Engineering reviews include traffic impact to area roads (improvements needed), streetlights, temporary and permanent pavement striping, signs, roadway design, temporary traffic control during construction, interim and permanent traffic control and other related traffic issues. Comments are forwarded to the DSC within 21 days. Revised 3/97 Page 1 - 16 Introduction Public Works Specifications and Standards Ve De, ae S · Ce D· Acceptance Inspections: Traffic Engineering is invited by the DSC prior to the release of related bonds to inspect any traffic striping and any electronic traffic control devices installed by the developer which are to be dedicated to the City. Traffic Engineering is not normally invited to the acceptance or final inspection meeting itself. If the DSC determines that such expertise is needed, Traffic Engineering will participate in the entire final inspection meeting. Public Works Real Estate Bureau Working MeetingsfPre-s~b~ittal Meetings~ Unless unusual real estate actions are anticipated, or unless the developer anticipates a need for acquiring City property (or for the City to acquire additional property), Real Estate normally does not participate in these early discussions. Preliminary Plat: Again, unless unusual real estate actions are anticipated, or unless the developer expects a need to acquire City property (or for the City to acquire additional property from a developer), Real Estate normally does not review this submittal. · Copies of comment sheets, letters, and responses to developers are provided to Real Estate by the DSC for information and to ensure the Real Estate Bureau is aware of development progress where appropriate. Site Plan: I · Not applicable to Real Estate unless some unusual conditions exist as determined by the DSC. · Copies of DSC comment sheets, letters, and responses to developers are provided to Real Estate for information to ensure that the Real Estate section is aware of development progress where appropriate. Acceptance Inspect~QDs: Usually, not applicable to Real Estate, unless a special condition is required of a developer. Revised 3/97 Introduction Page 1 - 17 Public Works Specifications and Standards VI. E_~. Final Subdivision Plat: The DSC provides a copy of the final subdivision plat for Real Estate review prior to recordation only when an unusual issue involving the City arises. In these cases, reviews identify any actions necessary to ensure that the City receives the proper dedications, etc. Most plats include the dedications of right-of-ways and no additional City Real Estate Bureau actions are necessary. · Occasionally, when deeds, agreements, or other legal documents are necessary, action by the Real Estate Bureau is required. Real Estate follows through on these issues so that they are identified and that correct action is taken with the City Attorney's Office to ensure that deeds and plats are properly recorded to protect the City. Public Works/Engineering/Surveying: A: Working Meetings/presubm~ttal Meetings There is normally no involvement of the Surveying Bureau in these meetings. However, information about the use of proper datums on all development plans and plats is discussed. B. Preliminary Plat: No normal review by the Surveying Bureau of this submittal. If the DSC requires a surveying review for a known unique condition, preliminary plats are provided to the Survey Bureau by the DSC for review within 7 days. C. Site Plan: No normal review by surveying of this submittal. D. Acceptance Inspections: No action by surveying during the inspection unless a surveying problem is identified by the DSC, and participation by Public Works Surveying is requested. Final Subdivision Plat: Upon receipt from the DSC, Public Works Surveying reviews the document for proper monumentation of City dedications and property boundaries, proper use of Datums, the State Plane Coordinate System Page 1 - 18 Introduction Revised 3/97 Public Works Specifications and Standards and other general and boundary related items. Review comments are provided to the DSC for correction before recordation. The consultant who seals the plat with his or her professional seal guarantees the accuracy and correctness of the survey itself. F. As-built Submit.tals: The Survey Bureau performs field surveys to check the completion and accuracy of monumentation, all storm drains, sanitary sewer systems, grades, and right-of-ways before the release of bonds where the developer's consultant is not required to survey these completed items. It is anticipated that a portion of this requirement will shift almost entirely onto the developer's consultant in the near future. VII. Mapping: A. Working Meetings/Pre-submittal Meetings: There is normally no involvement of the Mapping Bureau in these meetings. B. Preliminary Plat: No normal review by the Mapping Bureau of this submittal. If the DSC requires a mapping review for a known unique condition, preliminary plats are provided to the Mapping Bureau by the DSC for review within seven (7) days. C. Site Plan: No mapping involvement during the site plan review process. D. Acceptance Inspections; No mapping involvement during the inspections. E. Final Subdivision Plats: The Mapping Bureau reviews final plats for accuracy of GPINs and verification of changes in lot/boundary lines, that all lots/boundaries have directions and distances and that the lots/boundaries close on the Mapping Computer System. After recordation, the duplicate final subdivision plat is returned to Mapping by the Clerk of the Circuit Court for inclusion in the mapping system and filing. Revised 3/97 Introduction Page 1 - 19 Public Works Specifications and Standards VIII. F. As-built Submittal: The Mapping Bureau receives the record drawings from the DSC and inserts the basic outline of the new improvements into the City mapping system. The City Mapping Bureau coordinates the reproduction and distribution of record drawings when requested by Public Works Engineering's Storm Water Management and Public Works Operations Management sections. Permanent filing of as-built and record drawings is provided by the Mapping Bureau. Public Works Operations: ae Be C. Working Meetings; Public Works Operations attends developmental working meetings when needed. The DSC will ask for expertise and additional guidance on long term maintenance for engineering issues on development reviews from Public Works Operations. Complaints/Problem Solving: Public Works Operations maintains a Customer Services Office to receive Public Works' types of complaints. They provide a central point of contact. Operations can quickly ascertain if a complaint involves an ongoing development which is then quickly referred to the engineers, project managers and the Civil Inspectors in the Planning Department. Feedback to all. Offices to Improve Performance: Public Works Operations provides feedback to the DSC as well as Public Works Engineering to improve the Engineering Standards and to identify problems. These in turn are passed on to the consulting community and written into the Public Works Specifications and Standards manual where appropriate. This feedback is not just one way, but is a continuing interchange of ideas and improvements among Planning, Public Works, the consulting community, HRPDC, Tidewater Builders Association (TBA), Hampton Roads Utilities, and Heavy Contractors Association (HRUHCA), and various manufacturers of products for infrastructure. Page 1 - 20 Introduction Revised 3/97 Public Works Specifications and Standards CHAPTER 2 MATERIALS SECTION 2.0 General All materials shall conform to the specifications provided in Division II of the Virginia Department of Transportation Road and Bridge Specifications, 1994; unless otherwise specified herein. 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 hydraul~Gally 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. Ail storm sewer pipes and culverts shall be installed in accordance with the Virginia Department of Transportation Road and Bridge Specifications, 1994, and the ~ Department of Transportation Standard~, (1993), drawings 107.01, 107.02, and 107.03. Ail storm sewer pipes and culverts installed in the right of way as well as public easements, wherever pipes may be subject to traffic loadings, shall be backfilled with granular material placed in six (6) inch lifts and compacted to 95 percent of standard density based on AASHTO Specifications T-99 (ASTM D698).

Revised 3/97 Geometric Alignment & Design Page 3 - 5 Public Works Specifications and Standards S, EC~.ION 3.7.1 Vertical Curves and MinoF Intersecting streets Ail proposed streets and roads with a centerline vertical profile grade difference of one (1) percent or greater must be designed with vertical curves at least 100 feet in length. The length of a vertical curve shall be determined by the passing sight distance noted in the Virginia Department of TraDsportation Road and B~idge Standards, (1993), for roads with posted speed over 25 m.p.h., or a length appropriate for the design speed of the facility. Vertical curves may be eliminated in minimum grade changes when requested by the developer's engineer, after review and approval of the specific plans submitted. Minor intersecting streets must have negative gradelines falling away from the major through streets with vertical curves on the approaches of the minor street to the major through street. SECTION 3.7.2 Open Cuts Open cutting of existing roadways will not be allowed unless under extreme circumstances. All open cut requests must be made in writing, with substantial justification which may include dig-up information to verify conflicts, for review, prior to plan approval. Should an open cut request be approved, an appropriate traffic control plan must be included on the plans and approved by the Department of Public Works. Open cuts may be allowed subject to approval on site plans and subdivisions for all minor and residential streets, except where conditions would logically warrant boring or jacking of the proposed crossing. The open cut pavement replacements must meet the minimum pavement replacement criteria included in Chapter 5 of this specification and Appendix C, detail C-3 or C-4, as applicable. Open cuts shall be avoided when possible. Designers and review engineers shall consider the following: a) b) c) Number of vehicles per day Traffic congestion Ease of installation Page 3 - 6 Geometric Alignment & Design Revised 3/97 Public Works Specifications and Standards d) e) f) g) Cost of jacking vs. inconvenience to the public Age of the existing pavement Condition of existing pavement Is the existing pavement scheduled for overlay in the near future Temporary pavement patch material must be available on- site prior to the commencement of any open cut activity. Water lines and mains shall be installed with the construction of the roadway at the time of the project or be bonded as per the direction of Public Utilities. If a future water line retrofit of new subdivisions is necessary, provisions shall be made with Public Utilities and Public Works at the time of plan review/approval where future water lines will be installed. This includes mainlines and service taps. SECTION 3.7.3 Right-of-Way Dedication for Site Plans With the development of a site, a right-of-way dedication is required if the traffic generated by the development can be shown to create the need for the dedication. If traffic projection fails to justify the dedication, then a right-of-way reservation is required. SECTION 3.7.4 Site Plan Right-of-Way Reservation On site plans where the developer is not making any use of the future right-of-way other than for entrances, a reservation agreement is not required. The site plan shall show the existing and ultimate right-of-way lines and the building setback shall be measured from the ultimate right-of-way line. Where the developer desires to use all or any portion of the future right-of-way for additional parking, etc. a reservation agreement will be required prior to the release of the approved site plan. In addition, the setback shall be measured from the ultimate right-of-way line. No structures shall be permitted within the reserved area. SECTION 3.7.5 Right-of-Way Improvement Requirements for Site Plan a) Right-of-way improvements are required with the development of sites and are required to be shown on the site plan prior to site plan approval. Revised 3/97 Geometric Alignment & Design Page 3 - 7 Public Works Specifications and Standards b) c) d) e) Accepting or requiring an escrow (or bond which serves this purpose) is a last resort and is discouraged because the value of the escrow amount decreases with time and obtaining the physical improvements is the primary objective. Escrows will be required where projects are in the C.I.P. regardless of pavement widening. An inflation factor should be applied to provide adequate cost when the improvements will be installed in the future. Sidewalk, curb and gutter, drainage and streetlights are a necessity whether a Capital Improvement Project exists or not. These improvements will not be waived except in unusual or impossible cases such as when sidewalks do not connect to other sidewalks or there are few in the area, or no adjacent piped storm drainage or curb and gutter; as justified, in writing, to the Director of Public Works. In no case will streetlighting be waived. In addition, pavement widening is a safety requirement and upgrading road frontage (widening up to 3') to an existing street section may be necessary regardless of C.I.P. improvements and will not be waived unless in unusual or impossible cases. The widening does not entail additional lanes nor is traffic impact justification a necessity. Requiring additional lanes for construction shall be substantiated by traffic generation. SECTION 3.7.6 Right-of-Way improvements including curb and gutter, drainage, median crossovers, and left turn lanes on City highway projects I. General Guidelines for all Cases ae It should be stressed that where highway improvements are provided with the project in return for right-of-way dedications the values of each should be fairly comparable. Be Before any highway improvements are eliminated from a highway project because of right-of-way Page 3 - $ Geometric Alignment & Design Revised 3/97 Public Works Specifications and Standards negotiations, it shall be determined by the Director of Public Works that this will not be detrimental to the project. Ce Every attempt should be made in each situation to be consistent in applying these policies. De This section applies only to projects which are constructed entirely with City funds. Federal Aid and State projects do not allow installation of street improvements to be a consideration in the negotiations for right- of-way. II. Right-of-Way Negotiations This section is intended to provide guidelines for the operating departments in right-of-way acquisition and construction of right-of-way improvements on City highway projects. It is recognized that there are certain instances where highway improvements which would not normally be constructed as part of a City project can be provided in return for right-of-way dedications. The following guidelines should be used in determining when certain right-of-way improvements should be included in a project and under what circumstances improvements can be exchanged for right-of-way dedications. A. Unimproved Properties On all unimproved properties the owners should be advised that the City can install as part of the highway project certain road improvements (curb and gutter, sidewalks, entrances or street connections) at no cost to the owner provided that all right-of-way and easements needed for the roadway widening are dedicated. In addition, where median strips are proposed on the highway project, median crossovers and left turn lanes may also be provided if the estimated cost of all the improvements is substantially the same as the estimated market value of the right-of-way and/or easements required; provided that the median crossovers and left turn lanes meet certain minimum requirements as outlined herein. If the estimated cost of such improvements is substantially greater than the value of the right-of-way, the city may construct as a part of the project those Revised 3/97 Geometric Alignment & Design Page 3 - 9 Public Works Specifications and Standards Be improvements costing more than the value of the right-of-way dedicated, provided that the owner pays the City the estimated cost difference between the value of right-of-way and of said improvements. Excluded from this section on unimproved properties are the following: Unimproved Single Family Lots- In those cases where there exists a single unimproved residential lot in a residential neighborhood, attempts should be made to secure a dedication of all right-of-way needed. However, even if unsuccessful in securing a dedication, construction of the improvements along the property may still be included with the project if it is determined that these improvements will be in the best interest of the public. · In cases where the present or any previous property owner was required to dedicate right-of-way as a condition of rezoning, subdivision or site plan approval, improvements should not be considered for construction. Generally, as a condition of rezoning, subdivision or site plan approval installation of street improvements by the property owner is required. However, if the cost of street improvements was previously placed in escrow with the City by a property owner, the City would install the necessary improvements with the project using the funds that are held in escrow for this purpose. Improved Properties Where right-of-way is required from properly zoned and improved; (1) commercial (2) apartment (3) office (4) industrial and (5) residential properties, attempts should be made to secure a right-of-way dedication. However, even if unsuccessful the improvements along this property may be installed as part of the project. This approach is taken for Page 3 - 10 Geometric Alignment & Design Revised 3/97 Public Works Specifications and Standards III. Ce ao several reasons: (1) If improvements are not constructed with the project a patchwork road would develop. The property owner may have little reason to expend the funds necessary for additions to existing buildings or a change in use of the property. (2) If he was content with the operation of the site before the road improvement, there would be little chance of his installing the improvements at his expense. (3) The owner may have been required under previous site plan approval to install the improvements and due to a modification in road alignment, the improvements could not be used in conjunction with the new project. It would be an unfair financial burden to require him to pay for the improvements twice. Improved Non-Conforming Use Properties There are numerous properties existing in the City that are zoned for one type of use but are being used for another (i.e. commercial zoned property improved with a residence). In those cases where it is felt that proper development of the property will occur in the near future, the improvements may be installed only in return for a right-of-way dedication. Should the owner refuse to dedicate, he will be compensated for the right-of-way and be required to install with future development the street improvements along his property. However, in those areas where it is felt that development may be in the distant future, improvements may be installed as a part of the project if it is determined that installation of the improvements will be in the best interest of the public. In all of the above cases the property is handled on an individual basis with a final determination reached after review by the Director of Public Works. Design criteria and justification for Median Crossovers and Left Turn Lanes First priority for median crossovers will be given to existing intersecting city streets in order to provide for the smooth flow of Revised 3/97 Geometric Alignment & Design Page 3 - 11 Public Works Specifications and Standards · C~ traffic through the intersection. The cost of these crossovers and left turn lanes are to be included in the city's project cost. Second priority should be given to existing major traffic generators; for example, hospitals, schools and large shopping centers, provided the location of the crossover allows a minimum crossover spacing in conformance with the design criteria of the Virginia Department of Transportation Standards and Specifications. At public facilities, such as schools, hospitals, fire stations, etc., the city will bear the expense of providing median crossovers and left turn lanes at project cost. In the case of private development, the city should request the property owner to bear the expense of the left turn lane and crossover as outlined in Section I above. This, of course, is dependent on the crossover location meeting the standard crossover separation and other traffic and safety requirements that may apply. Also, included in this are proposed subdivision streets and proposed large commercial developments whose construction is planned to follow the highway project. In these cases, crossovers and turn lanes should be handled with the right-of-way negotiations as outlined above. It is desirable to construct crossovers and turn lanes in advance of the proposed development. This eliminates the need to later enter onto the new roadway and disrupt traffic in order to construct these facilities when development occurs, and it also provides a more desirable appearance since subsequent cutting and patching of pavements and curbs are eliminated. It also aids the City in insuring that the crossover and entrance locations are adhered to when the adjacent lands are developed. Third priority should be given to minor traffic generators; for example, small businesses, churches, service stations, etc., provided safe distances can be achieved between crossovers, and traffic volume on the major thoroughfare is such that conflicting movements can be safely permitted. In these Page 3 - 12 Geometric Alignment & Design Revised 3/97 Public Works Specifications and Standards instances, the property owners should bear the expense of the crossovers and turn lanes, either by cash payment or through equivalent value of dedicated right-of-ways as outlined above. SECTION 3.7.7 Major Right-of-Wa~ Improvements - Development This section applies to all roads on the Master Street and Highway Plan projected to pass through or abut a proposed development. a) The requirement for improvement to four or more lane roads shown on the Master Street and Highway Plan should depend in part on access to the road from interior streets in the subdivision. b) Where improvement is necessary, it shall be required along the entire length of the right-of- way adjacent to or passing through the subdivision. Any improvements required for a development fronting on a roadway that is not part of an active project, either City funded or State funded, will be installed by the developer. c) Where there is no interior street connection to the right-of-way in question, and where it would not be feasible or reasonable on the basis of traffic circulation to require such a condition, then no improvement may be required, at the discretion and judgement of the review engineer. d) Regardless of the requirement for improvement, full right-of-way dedication shall be required in all cases. e) The developer of all subdivisions in such a situation and any site plan which generates the need for improvements at the time of development is to dedicate to the City of Virginia Beach that part of the proposed right-of-way which lies within the property boundary, and to deposit in the subject road project account with the City of Virginia Beach 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. However, at the time of plat recordation or site plan release the developer is Revised 3/97 Geometric Alignment & Design Page 3 - 13 Public Works Specifications and Standards f) g) h) ±) responsible for only that part of the right-of-way shown on the plat or site plan. Before construction of the road, the City will provide the remainder of the cost for the ultimate section. The standard City street consists of a 30-foot curb to curb pavement section, curb, gutter, sidewalk on one side, and drainage, all to accepted City standards. This cost will be determined by the City Engineer in accordance with recent construction cost estimates. If construction of part of the length of the road is necessary to provide immediate access to the proposed project, then a minimum of two lanes of the ultimate section of the road sufficient to provide immediate access shall be designed and constructed by the developer. In this event the developer will be given credits for all expenditures in excess of what it would cost to construct a standard City street. The road project deposit requirements, as listed in the previous paragraph, shall apply to the remaining length of the proposed road. If, at the time of plat recordation, the Virginia State Highway Commission has accepted the proposed improvement as a Virginia Department of Highways and Transportation project, then the developer's participation would be reduced by the current percentage of participation by the state. However, there will be no reimbursement if funds have been posted and subsequently the project is accepted as a State Project. The cutoff for requiring escrows will be the date of council's resolution approving acquisition of right-of-way for a project. In the event the City does not commence construction of the project within five (5) years after the completion of the final section of the subdivision, a reimbursement of any funds which have been posted will be made. Where perimeter roads consist of a right-of-way 60' or less, the participation will be 50% of the cost to construct a standard City street. Page 3 - 14 Geometric Alignment & Design Revised 3/97 Public Works Specifications and Standards · · · widening including pavement transition (minimum 50') is required based on traffic impact, safety and/or development generated need. The width and length of widening shall be determined upon review by Traffic Engineering. The Department of Public Works Engineering Plan Review staff, in coordination with Traffic Engineering, shall require pavement widening and full right-of-way improvements when necessary. Should a proposed development not be required to comply with substantial pavement widening, as defined, and the necessary pavement width to construct the ultimate right-of-way improvements in excess of the incidental pavement widening definition (3' or less), curb and gutter will not be required to be constructed along the development site frontage. Right-of-way requirements, including sidewalk, storm drainage facilities and street lighting, will be evaluated independent of the pavement widening and curb and gutter requirements and shall be required, as determined upon review, by the Public Works Engineering Division Plan Review and Traffic Engineering Staff. Right-of-way Improvements shall be based upon the criteria listed for the following developments: a) Commercial, Apartments, Condominiums 1. Traffic impact study, if required 2. Curb and gutter in the area · Vacant developable property in the area which could add improvements 4.

SECTION 3,.10 Turk 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 Lane Justification When the location being studie~ generates thirty-five (3~) or more right turn entering p~ak hour trips into a single entrance, a right turn lane will be required. Other factors such as accident history and analysis, pedestrian conflicts, and the existing highway capacity must also be considered for the justification of the installation of a right turn lane and will be determined by the City Engineer and/or City Traffic Engineer. Page 3 - 36 Geometric Alignment & Design Revised 3/97 Public Works Specifications and Standards SECTION 3.10.3 Right Turn Lane Geo~etrics a) 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 = 50'/50' 30 MPH to 35 MPH = 100'/100' Greater or equal to 40 MPH = 150'/150' At signalized intersections, storage length should be based on two (2) times the average number of vehicles that would store per signal cycle using 20 feet per vehicle (peak hour) depending on the cycle length, signal phasing and vehicle arrival/departure rates. The storage lane length shall not be less than the minimum, based on roadway speed. b) Bay Taper - A straight taper along the right edge of the travelled way is used to guide vehicles into the turning lane. A short radius should be used at the beginning and end of the bay taper. c) Width - A twelve (12) foot turn lane width is required for right turn lanes with any new road projects or development. The width of the turning lane shall not include the gutter pan. If the turn lane will in the future be incorporated into and as part of a widening of the roadway as an outside travel lane, then the right turn lane shall be 13 feet wide, plus a 2 foot wide gutter pan. Ail other aspects of the turn lane in this case shall be designed to match future design for widening, such as drainage, pavement thickness, landscaping etc. 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 50' on tangent is required between the end of the entrance radial curb and the end of the bay taper. This distance should be as long as possible. SECTION 3.10.5 Right Turn Lanes for Corner Sites See the City Subdivision Ordinance Sec. 4.4.2. This ordinance shall also be used as a standard for parameters concerning traffic engineering and design for site plans Revised 3/97 Geometric Alignment & Design Page 3 - 37 Public Works Specifications and Standards that are high traffic generators on corner lots. For geometrics see Appendix D, sheet D-4. SECTION 3.10.6 Right-of-Way Dedication for Right Turn Lakes Right-of-way dedication for turn lanes will be required when turn lanes are justified and required by the City. SECTION 3.10.7 Left Turn Lane Justification When the location being studied generates thirty (30) or more left turn entering peak hour trips into a single entrance, a left turn lane will be required. However, other factors such as accident history and analysis, pedestrian conflicts, and the existing highway capacity must also be considered for the justification of and to require the installation of a left turn lane. This will be determined by the City Engineer and/or City Traffic Engineer. Page 3 - 38 Geometric Alignment & Design Revised 3/97 Public Works Specifications and Standards SECTION 3.10.8 Left Turn Lane Geometrics a) Storage Length - Storage length of a left 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 The greater of either a critical gap analysis using a length double the average number of vehicles stored at 20 ft per vehicle, or the following table. 25 MPH = 50'/50' 30 MPH to 35 MPH = 100'/100' Greater or equal to 40 MPH = 150'/150' 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 the cycle length, signal phasing and vehicle arrival/departure rates. The storage lane length shall not be less than the minimum. b) Bay Taper - A straight taper along the left edge of the travelled way is used to guide vehicles into the turning lane. A short radius should be used at the beginning and end of the bay taper. c) Width - A twelve (12) foot turn lane width is required for left turn lanes with any new road projects or development. The width of the turning lane shall not include the gutter pan. The dimensions will be reviewed on a case by case basis, where site frontage is limited, or where existing right-of-way is not sufficient. SECTION 3.10.9 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 × 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 Revised 3/97 Geometric Alignment & Design Page 3 - 39 Public Works Specifications and Standards SECTION 3.11 Median Crossover spacing SECTION 3..11.1 Sp_acing 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 Road Design Manual.

SECTION 3.15.2 Reduction of Mi~m%%~ spacing S~andards Consideration in crossover spacing less than the established minimum will be given for intersecting p_u~ roadways with a current ADT of 100 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 or the City Traffic Engineer. Page 3 - 40 Geometric Alignment & Design Revised 3/97 Public Works Specifications and Standards SECTION 3.1~.$ight Distance SECTION 3.12.1 General The following standards in Section 3.12 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 Distanc,e 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 $5th percentile speed should be used if available for improved accuracy.

If the soils are relatively uniform, then the full 10 foot deep soil boring and complete soil tests may be required only at 1,000 to 1,250 foot intervals instead of every 500 feet. However, a CBR test is still required evey 500 feet, regardless. Resilient Modulus (MR) = 1,500 x CBR value (if no resilient modulus test are performed this may be used as an approximation. SECTION 4.4 Atterberg Limits Atterberg limits for proposed pavement designs shall be included in the soil report. Atterberg limits for subbase and aggregate base material shall conform to the Virginia Department of Transportation Road and Bridge .Specifications (1994), Section 208.

Where the pH value is outside this range, steps shall be taken to prevent chemical attack on metal pipes and geotextile fabrics. SECTION 4.9 Soil Exfiltration and Percolation Test Permeability tests shall be included in the soil report when volume control BMPs are proposed. Soil exfiltration (percolation) test for volume control of infiltration BMPs shall be performed at trench excavation prior to the installation of the BMP. The results of the exfiltration test must clearly establish the suitability of the soils to function as an infiltration system. SECTION 4.10 Ground Water Elevation The existing ground water elevation must be shown in the soil report along with the seasonal high groundwater elevation. Any infiltration design BMPs and pavement designs must take into consideration the seasonal high ground water elevation and fluctuation as shown on the seven (7) year ground water fluctuation chart in Appendix C-13. SECTION 4.11 Soil Reports for ~aveme~ Design Soil reports for pavement designs must indicate the depth of material tested to ensure it coincides with the proposed subgrade elevation. SECTION 4.12 Specification Block A moisture - density specifications block will be developed for each soil material used in a pavement section (subgrade, borrow, fill,subbase, and base material). SECTION 4.13 Field Inspection Appropriate field inspection is required by Public Works Inspectors to verify proper material and placements. The Revised 3/97 Geotechnical Information & Design Page 4 - 3 Public Works Specifications and Standards inspectors will verify placement according to the Spec Block for the materials. SECTION 4.14 Recommendations A licensed soil engineer's remarks and recommendations shall be provided. All tests included in the analysis shall comply with the appropriate ASTM and AASHTO designation. SECTION 4.15 Embankments and Fill Ail embankments shall consider underdrains and reinforcement with geotextiles or geogrids unless adjacent to a lake, canal or pond steeper than 3.0 (horizontal):l (vertical) and higher than five (5) feet; see Section 5.4.2 and Appendix E for further information on geotextiles and geogrids. The design engineer shall evaluate this issue. See Section 8.8 "Open Drainage Systems" for requirements on slopes adjacent to lakes, canals, and ponds. Whenever a subdivision or site plan is proposed where fill has been previously placed under a proposed pavement, dwellings , or other structures, the design engineer shall have a licensed soils engineer make recommendations to avoid settlement. If an area is being filled, then the owner shall cause a plat to be put to record in the circuit court identifying the fill area for future information to owners developers and builders. A note must be shown on such plat relating that any developer or subdivider shall hire a licensed soils engineer for recommendations before construction of any type. SECTION 4.16 Soil Classification by Settlement Jar for Rough Field Estimates The settlement jar technique may be used to field estimate rough percentages of sand, silt and clay in a soil. This technique requires a one quart jar or larger (with graduations on the jar) with a lid. A soil sample should be carefully placed into the jar to fill the jar approximately one third (~) to one half (½) full. Then fill the remaining portion of the jar with water. Shake well until thoroughly mixed. Then let settle and mark the different layers that settle. From this a rough percentage of sands, silts, and clays can be determined as follows: Page 4 - 4 Geotechnical Information & Design Revised 3/97 Public Works Specifications and Standards a) Sandy material settles out within approximately 90 seconds, which will form on the bottom of the jar. b) Silty material settles out in approximately 10 to 40 minutes, which will form a middle layer of settled soil material. c) Clay material settles out in approximately 4 or more hours or not at all, will form the top layer of settled soil material. Mark or make note of the above amounts of soil settlements relative to the final overall amount of soil settlements. This will give the percent of sand, silt and clay in the soil.

SECTION 6.2.3 Design Standards i · The following are guidelines which shall be adhered to during plan preparation. The numerical sequencing is only an aid and is not intended as a hierarchy or priority of significance. ao The roadway width shall be 36 feet when measured face-to-face between the curbs. be The roadway cross section shall include curb and gutter (type CG-6). Ce The roadway cross section is centered within the roadway right-of-way. de A cul-de-sac is normally located at the end of the existing roadway and shall not extend into the dune line. Se A cul-de-sac shall have a minimum pavement radius of 35 feet. fe ge On street public parking is provided and maximized. The existing street lighting is evaluated. The resulting street lighting design plan shall meet all current City standards for residential illumination. he Encroachments in the right-of-way such as landscaping and physical structures may be removed as necessary to accommodate construction. The property owner shall have Page 6 - 6 Incidental Concrete Construction Revised3/97 Public Works Specifications and Standards i® j · k· l, m· adequate notice and opportunity to relocate the encroachments prior to the start of construction. The face of curb radii shall be a minimum of 35-feet at the intersection of the project street with Atlantic Avenue. The existing traffic control signing and pavement marking is evaluated. The City shall ensure the project design conforms to the current standards and requirements of the Manual on Uniform Traffic Control Devices (MUTCD). The required installations shall conform to current Public Works/Traffic Engineering standards. The pavement section will be constructed of asphaltic concrete designed for the existing soil conditions. Existing exposed-aggregate finish driveway aprons and parking pads are replaced in-kind, unless in conflict with VDOT of ADA standards. All other aprons and pads are replaced with class A-3 concrete. If the property owner elects to upgrade the driveway or parking pad to an exposed aggregate finish, the property owner must pay the cost differential (exposed aggregate vs. A-3 concrete finish). This is a material standard; see item #13 below for geometric criteria. Each single-residential unit requires two parking spaces. Where adequate on-site parking exists or is required by the approved site plan, one 12-foot wide driveway is designed so as to tie into that parking area. Where on- site parking does not exist or is not required as part of the approved site plan, a 20-foot wide parking pad for two cars is designed within the right-of-way. For multi-residential units, each unit requires two parking spaces. Where adequate on-site parking exists or is required with the approved site plan, one 12-foot wide driveway is designed so as to tie into that parking area. Where on-site parking does not exist or Revised 3/97 Incidental Concrete Construction Page 6 - 7 Public Works Specifications and Standards is not required as part of the approved site plan, parking pads are designed within the right-of-way using the following widths: 4 cars = 36 feet 6 cars = 48 feet 8 cars = 64 feet The width of the parking pad will not exceed the lot width. Any existing entrances and parking pads within the right-of-way shall be modified to meet the criteria set above. Refer to chart (Figure VI - 2, Entrance Detail). Whenever on-site parking is available or required as part of the approved site plan but does not provide the minimum required number of parking spaces, the City shall amend the parking pad widths described above by deducting for any parking which is provided or required by the approved site plan. The City will coordinate with the property owner to design the most practicable parking. For example: a single residential unit has no existing on-site parking but the approved site plan stipulated one space was required. The City will design a 12-foot wide driveway which shall extend through the full right-of-way for parking of one vehicle and the property owner shall provide a parking space as required by the approved site plan. SECTION 6.2.4 Petitions The petitions used in this program are presented on page 6-17 of this manual. SECTION 6.2,~ Procedures I · General. The following procedures specify the necessary activities and their sequence for implementing the North Beach Street Cost Participation Program. See Figure VI - 1, Process Flow. ae Select a Block Captain: The property owners for each affected block must select an individual to represent them as Block Captain. Page 6 - 8 Incidental Concrete Construction Revised3/97 Public Works Specifications and Standards be C. de e. The Block Captain will coordinate the activities of this program and serve as liaison with the City. The city will coordinate all activities of this SECTION through the Block Captain. Petition for Preliminary Design: Petitions are circulated and collected by the Block Captain. Each separate parcel of property with frontage on the project street is allotted one vote for participation during the petition process. The ~reliminar~_ design ~lan is prepared only after the City receives petitions favorably re=uestina the Dro4ect from at least 85% of the affected property -- -- -- ~ The City will retain the original petitions on file and will return copies to the Block Captain for use during the next petition activity after the public workshop. See Figure VI - 2, Entrance Detail and paragraph 2 below for determination of costs. The time allowed for preparation and delivery of the petitions to the City is 60 days. Preliminary Design Plan Preparation: Individual cost participation requirements are also determined for the affected properties. The preliminary design plan is prepared in accordance with the Design Standards, outlined in this section. It typically takes 60-90 days for development of preliminary design plans. Review Preliminary Design Plan: The preliminary design plan is given to the Block Captain to coordinate review by property owners. The Block Captain will contact all property owners and afford them an opportunity to review the preliminary design plan and individual property owner cost participation requirements. The Block Captain will document all contacts. After all property owners have been contacted, the Block Captain will request that the City schedule a public workshop (typically held 30-45 days after receipt of the preliminary design plan). Public Workshop: The City will schedule a workshop to allow affected property owners an Revised 3/97 Incidental Concrete Construction Page 6 - 9 Public Works Specifications and Standards f. ge opportunity to discuss the scope, cost participation, time schedule and plan details of the project with City officials. Property owners may request clarification of, or changes to the preliminary design plan or cost participation requirements at this workshop. Typically, the duration of the workshop is 2 hours. Post Workshop Activities: The City will review the requested changes and revise the plans and cost participation requirements when appropriate. The City will return to the Block Captain copies of the original, completed petitions with cost requirements for final execution by the property owners. The revised plans and cost participation requirements will be returned (typically 45-60 days after the workshop) to the Block Captain for final review by property owners. During this final review, all property owners must return to the Block Captain their signed petitions (bottom portion) with their attached checks or a brief letter describing their objections to the project. If a property owner cannot or will not pay his/her portion, another property owner or group may voluntarily contribute the portion required. The City must receive favorable netitions from -- -- SS% of ~he propert~ Qwner9 and must secure full ¢1~0%) Cos~ participation before final plans and construction documents are ~re~ared. The time allowed for post workshop activities is 90 days. The project is terminated if the above stated conditions are not met. If the above stated conditions are met but the property owners later decide to terminate the project, the property owners shall not receive reimbursement for any cost participation; the only exception to this reimbursement policy is described below in item H: failure of the City Council to approve funding. Final Plans and Construction Documents Preparation: It typically takes 60-90 days Page 6 - 10 Incidental Concrete Construction Revised3/97 Public Works Specifications and Standards for preparation of construction documents. final plans and he Post Final Plans and Construction Documents Activities: Once the final plans, construction documents and total project costs estimate are completed, the project is presented to Council for full funding. If Council approves full funding for construction, the project is bid and a construction contract is entered. It typically takes 120-180 days from Council approval to start of actual construction. If Council does not approve funding, the affected property owners will receive full refunds according to their actual paid cost participation amounts. This amount will include any contribution made towards the participation requirement for another property. SECTION 6.2.6 Cost ~art~cipa~ion le Standard Lots: Each separate parcel of property with frontage on the project street will pay the cost participation requirement stipulated in Figure VI - 2, Entrance Detail. · Cul de Sac: Where cul de sac improvements are proposed in the right of way, frontage shall be determined based on the right of way of the project street, i.e., the straight line distance from property line to property line along the right of way, regardless of the location of the cul de sac. The full criteria stipulated for cost participation in Figure VI - 2, Entrance Detail are applicable. · Corner Lots: If the property abutting a roadway intersection has a circular property line on the right of way being improved, the definition of "frontage" is modified. The frontage shall be determined by connecting the tangents of the circular property line (extending two straight property lines to form a corner) and then measuring from this point of connection to the opposite property line corner on the project street. Revised 3/97 Incidental Concrete Construction Page 6 - 11 Public Works Specifications and Standards 4. Alleys: ae Private: Only the property owner having frontage along the project street will have a vote for participation. The alley is treated as a driveway entrance and subject to the cost participation criteria stipulated in Figure VI - 2, Entrance Detail. be Public: Criteria established for "corner lots" and general criteria stipulated in Figure VI - 2, Entrance Detail will apply for those properties with frontage along the project street. 5. Special: For the property owner without an entrance on the project street, the cost participation requirement stipulated in Figure VI - 2, Entrance Detail will not include a width of driveway (since it has zero width). If the property owner has an existing entrance on the project street, the full criteria stipulated for cost participation in Figure VI - 2, Entrance Detail are applicable. If the property owner has an entrance/access on Atlantic Avenue but she/he desires an entrance with pad on the project street, the property owner must relinquish (close) that Atlantic Avenue entrance/access and follow the cost criteria described above for "an existing entrance on the project street." SECTION 6.2.7 Exceptional If the criteria above do not fully describe a particular situation, the situation is considered "exceptional." The City will determine cost participation requirements for exceptional situations on a case-by-case basis in concert with the precepts and principals outlined throughout this SECTION.

Variations from the standard location of sidewalks and bike paths may be allowed or required by the Department of Public Works due to topographical features or other physical features that may warrant the revision. SECTION 6.3.1 Construction of Bikeways Requirement The purpose of this section is to provide guidelines for requiring right of way and construction of bikeways during plan review. This section shall cover all bikeways included on the City of Virginia Beach Master Bikeway Plan. a) Bikeways included on the City of Virginia Beach Master Bikeway Plan or as amended, will be viewed in the same manner as streets included on the Master Street and Highway Plan during the plan review process. b) The City will require dedication of bikeways when the bikeway passes through or adjacent to developing property. A dedication of at least four (4) feet beyond the requirement of the Master Street and Highway Plan (MSHP) requires a separate bikepath facility on the city bikeway plan; except where the MSHP includes the bikeways. If a sidewalk would normally be installed or escrowed, then the bikepath is required to be built or escrowed instead of the sidewalk. c) Where monolithic sidewalk is required, it may be constructed monolithicly or may be constructed using #3 reinforcing steel dowels between the sidewalk and concrete curb and/or Revised 3/97 Incidental Concrete Construction Page 6 - 17 Public Works Specifications and Standards drainage structures placed 16" on center, or a ledge shall be provided in accordance with drawing #C-15. d) The City will require construction of bikeways when the bikeway passes through or adjacent to developing property and that development generates a need for the bikeway. This requirement can only be waived by the City Manager. ~CTION 6.3.2 Beach Borough Sidewalks The purpose of this section is to provide guidelines for requiring the construction of sidewalks in the Beach Borough. This section shall cover all sidewalks in the Beach Borough. a) Ail sidewalks shall be installed in accordance with the current Virginia Department of Transportation and the City of Virginia Beach Standards and Specifications. b) The north-south street sidewalks for Arctic Avenue, Pacific Avenue, and Atlantic Avenue between Rudee Inlet and 45th Street shall be a minimum of eight (8) feet wide. c) The east-west street sidewalks for Norfolk Avenue, 17th Street, 19th Street, 24th Street, 31st Street and 40th Street between the boardwalk and Arctic Avenue shall be a minimum of eight (8) feet wide. d) Ail sidewalks in the Beach Borough shall be installed monolithically with the curb unless sufficient engineering reason exists which would dictate that this is not practical. e) Any variance to this policy must be approved by the Director of Public Works. SECTION 6.3.3 Curb Ramps (Persons with Mobility Impairments) a) The thickness for curb ramps for persons with mobility impairments shall be seven (7) inches including flares to match the curb thickness and Page 6 - 18 Incidental Concrete Construction Revised 3/97 b) c) d) e) Public Works Specifications and Standards provide sufficient structural support for occasional vehicles which may ride over these areas. That seven inch thickness shall extend to the second construction joint from the curb which shall be a minimum distance equal to the width of the sidewalk/bikepath. When determining the proper corner or entrance radii requirements, use should be made of accepted turning templates for larger vehicles. The guidelines listed in this manual are minimum~adii, and every effort should be made to ensure good engineering judgement is used in determining the proper radii in each case and subsequent location of CG-12 curb ramps. Ail curb ramps shall be designed in accordance with the Code of Virginia (Section 15.1-381), the latest American with Disabilities Act(ADA) guidelines and VDOT interpretations as outlined in VDOT Location & Design Division Instructional & Informational Memorandum (LD-92 (D) 55.3 dated March 23, 1992, and the VDOT METRIC 1994 Road And Bridge Standards. See Section 2.4.1 for material information. The minimum width shall be 3' with a maximum 12'1 slope or flatter. Elimination of the requirement for installation of curb ramps must be based on an engineering reason such as a ditch or wall obstruction. An "accessible route" must exist before requiring a curb ramp. An "accessible route" must be at least 3 feet wide with a stable, firm and slip-resistant surface such as grass. A stable vegetated surface is considered slip-resistant. Curb ramps are required along these accessible routes; but it must be noted the curb standard ramps are required even if no sidewalk exists or is proposed. When a Standard VDOT CG-12 curb ramp is required, the entire curb ramp must be installed, in its appropriate location as the typical locations in Appendix A. No wipe downs in the curb line will be allowed in the "anticipation" of a sidewalk or future curb ramp being installed at a later date. Refer to the latest VDOT ~ Road and Bridge Standards and VDOT Volumes I & I Memoranda for the latest drawings, details and instructions for Standard CG-12 curb ramps. Revised 3/97 Incidental Concrete Construction Page 6 - 19 Public Works Specifications and Standards f) g) n) i) Curb cut ramps for the physically disabled shall be located at all intersections where both curbs and sidewalks or curbs and vegetated accessible spaces are provided and at other major points of pedestrian flow. The CG-12 ramps, where possible, are to be located, two to each corner directly across from each other at intersections so as to preserve curbs for use by the visually impaired at the crosswalk itself. CG- 12 ramps will be installed at both ends of each radius at the tangent, or as close as practical to the point of tangency within the radius and match the location of the cross walk and in front of the STOP BAR as these standards require, as shown in Appendix A. CG-12 ramps shall not be installed centered in the radius, particularly on high volume and/or high speed roadways which have no pedestrian signals.

B. Lot Grading "As-Built" D~awings 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 Revised 3/97 Site Plan & Subdivision Requirements Page 11 - 7 Public Works Specifications and Standards 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 ae 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. be 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. 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. de 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.) Se 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.

SECTION 16.2.8 Keep Right Si=ns -- -- -- a) The following criteria shall be utilized to establish the need for a KEEP RIGHT (type R4-7) sign installation. 1· KEEP RIGHT signs installations shall be required at all median noses of traffic signalized intersections where other signs do not obviously mark the need for motorists to keep to the right. · KEEP RIGHT signs shall be required where the median opening is located in a curved section of the roadway, or the through lanes do not align across the median opening. · KEEP RIGHT signs shall be required at median islands where unusual or unexpected traffic patterns have been established. · KEEP RIGHT signs shall be required and shall be mounted on the face of , or just in front of, any existing obstruction in the center of the roadway. · KEEP RIGHT signs may be required where accident history or an engineering study indicate the existence of a hazardous traffic condition that could be addressed by a KEEP RIGHT sign. · KEEP RIGHT signs shall not be required at intermediate ends of divisional islands or Revised 3/97 Traffic Control Page 16 - 43 Public Works Specifications and Standards medians that are located in straight sections of roadway. · KEEP RIGHT signs shall not be used at locations where other signs obviously indicate that the motorist must pass on the right. SECTION 16.2.9 Directional Signage a) Directional signs are intended to direct motorist to important landmarks, educational, historical recreational, cultural or government sites. In all cases, the color, shape and placement shall conform to the Manual of Uniform Traffic Control Devices and all applicable requirements of Section 2.10 of this manual. This policy applies to all directional signs installed in the City of Virginia Beach: · 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. · 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. · 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. · 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 Page 16 - 44 Traffic Control Revised 3/97 Public Works Specifications and Standards · o · · shall be installed within a reasonable proximity to the parking facility as determined by Traffic Engineering. 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. 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. 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. 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. City, state and national parks merit directional signs in some cases. Neighborhood Revised 3/97 Traffic Control Page 16 - 45 Public Works Specifications and Standards 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. 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. Page 16 - 46 Traffic Control Revised 3/97 Public Works Specifications and Standards SECTION 16.3 ~avement Markings The guidelines and requirements provided in this section are included in the revised "Pavement Marking Standards & Details" plan which contains typical pavement marking drawings. A copy of this plan may be obtained by contacting Traffic Engineering at 427-4491. SECTION 16.3.1 Crosswalks a) Crosswalk lines shall be solid white lines, six (6) inches wide, marking both edges of the crosswalk area. b) Crosswalk lines shall extend from edge of pavement to edge of pavement or edge of shoulder as applicable. c) Lines forming a crosswalk shall be parallel. d) The width of a crosswalk shall be eight (8) feet except in the Beach Borough or other heavy pedestrian areas where they shall be ten (10) feet. e) Crosswalk shall have (as required below) twenty- four (24) inch wide consecutive white rectangles seven (7) feet or nine (9) feet long and shall be installed perpendicular to the six (6) inch white lines. Spacing shall be approximately six (6) feet on center. They shall be located so as to avoid normal wheel paths. f) Warrants for twenty-four (24) inch longitudinal striping: 1) Where there is an exclusive pedestrian phase at a traffic signal; 2) Where there is a crosswalk within an identified school walking zone that has a crossing guard; 3) Where there are a substantial number of pedestrians and a crosswalk is unexpected. Revised 3/97 Traffic Control Page 16 - 47 Public Works Specifications and Standards SECTION 16.3.2 Stop Bars a) Stop bars, solid white lines being twenty-four (24) inches wide, shall completely traverse all traffic lanes on each approach at signalized intersections, or approaches with "STOP" sign control at major arterial roadways. b) Stop bars shall be located at a minimum of four (4) feet in advance of the crosswalk, unless otherwise specified on the plans. SECTION 16.3.3 Lane, Edge and Centerline a) White lane lines, either solid or mini skip shall be six (6) inches wide. b) Lane lines for thru lanes on an approach to a signalized intersection shall be solid white lines and they shall extend continuously from the beginning of the full width of the turning lane to the stop bar. Mini-skips shall extend from the lane line to the end of the transition. c) Edge lines, when noted on the plans, shall be solid white lines four (4) inches wide, but solid yellow lines are to be used when adjacent to a median which separates opposing directions of vehicular traffic flow.

SECTION 16.3.5 Gore Markings a) Markings shall consist of twenty-four (24) inch solid transverse lines spaced as required by Section 16.3.5 (c). b) Chevrons shall be used when specified on the plans. c) Twenty-four (24) inch median and gore markings shall be spaced according to the posted speed limit as follows: 1. 30 MPH and below - 8 feet on center 2. 35 MPH to 45 MPH - 16 feet on center 3. Greater than 45 MPH - 20 feet on center SECTION 16.3.6 Pavement Legends a) Legends shall be transversely aligned across each lane. The distance between the arrow symbol and the stop bar shall be eight (8) feet. b) Arrows and legends shall not be placed beyond the solid white lines. c) Word messages shall be located in advance of its accompanying symbol by a distance of not less than thirty-two (32) feet nor more than sixty (60) feet from the symbol. After fifth legend in a turn lane, spacing between legends may go up to eighty (80) feet maximum. For auxiliary (right and/or left turn) lanes on all approaches, legends shall be centered within the lane. They shall continue the length of the lane beginning and ending with a symbol. ~E~ION 16.3.7 Genera~ Notes a) Materials and workmanship shall conform to the City specifications. Revised 3/97 Traffic Control Page 16 - 49 Public Works Specifications and Standards b) c) d) e) f) g) h) i) J) Pavement markings shall be installed in accordance with the regulations governing the design, location, and operation of all official traffic signs, signals, and markings on and along highways within the Commonwealth of Virginia. Ail pavement markings shall be reflectorized in accordance with VDOT Road add Bridge Specifications, (1994) Section 246. The contractor shall prepare the pavement surface for the proper adhesion. Any sweeping or removal of debris, gravel, dirt, or other foreign materials shall be considered as incidental to the installation, and no separate payment made therefore. The contractor shall remove completely all previous markings, which in the opinion of the engineer, conflict with the new pavement markings. The contractor shall note all special provisions of the contract and specifically with regards to: The rate of application, maintenance of traffic, restricted working hours, and/or restricted weather conditions. No deviations will be permitted. Unless specified otherwise, the basis of measurement shall be alone the longitudinal centerline of pavement markings.

There are many conditions where the minimum height referenced above can not be used due to conflicts or restrictions with pre-development or post-development utilities, drainage items and pavement section. Engineering judgement is required in the design of any drainage structure. If the drainage pipe does not cross under a curb or curb and gutter, one can subtract 0.75 feet to the minimum height. Safety Slabs are to be provided at approximate 10' vertical intervals and are to be spaced so as not to conflict with the pipe openings. See page 106.13 of the VDOT, 1993, Road and Bridge StandArds, Volume 1, for more information. *** The maximum depth does not correspond to this combination of precast units but to the depth of the maximum number of precast units assembled into a drainage structure. See page 106.10 of the VDOT, 1993, Road and.

Dear Richard: On behalf of Tidewater Builders Association, I would like to thank you for the opportunity to comment on amendment number 3 of the Public Works Standards and Specifications Manual. The shelter industry considers the manual a great tool in being able to "know the rules up-front". Therefore, we solicit comments on proposed amendments, such as the current one, to our site development subcommittee. This committee consists of builders, developers, and engineers who regularly do business in Virginia Beach. With such a diverse membership and ultimately varying technical opinions, we do not routinely "endorse" the manual. However we received no comments/concerns from our subcommittee on the proposed changes in the draft amendment. We look forward to discussing future amendments in order to continue improving the manual on a routine basis. Sincerely, Dick Foster, Chairman Virginia Beach Municipal Affairs Chairman "Do Business With A Member" Affiliated w~th the Home Builders Associauon of Vlrg~ma and the ,"dauonal Association of Home Buff&rs SUMMARY PUBLIC WORKS SPECIFICATIONS AND STANDARDS MANUAL REVISIONS The agenda package for Council's April 1, 1997, meeting includes 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 by those individuals 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 Highlights of these revisions are summarized below CHAPTER 1 Section 1 7 has been added to reflect Public Works' role in development review and construction which is handled by the Planning Department CHAPTER 2 Various sections of this chapter have been revised to clarify language and intent, as well as to update materials specifications including storm drainage pipes, traffic signs and sign poles, and other traffic control devices A standard for recycled plastic decorative traffic sign posts for residential streets is added to complement a new drawing for the same in Appendix D CHAPTER 3 Several sections dealing with traffic control guidelines, entrances onto roadways, and roadway geometric design standards were taken out of Chapter 6, updated and inserted into Chapter 3 These sections previously shown in Chapter 6 are to be deleted and are crossed out in that chapter because these sections more appropriately belong in Chapter 3 Other sections involving engineering design guidelines, technical requirements for "As-Built" record drawings, and minimum shoulder width requirements were updated Section 3 7 14 was revised to require developments to install, at a minimum, adequate pavement width, an eight-foot wide earth and/or gravel shoulder, plus a relocated drainage ditch along existing road frontages where standard curb, gutter, sidewalk and other urban improvements are not appropriate due to the rural nature of the area or the character and specifics of the development CHAPTER 4 Only one page was revised to clarify and to give more flexibility to soils testing and subsequent pavement design options CHAPTER 6 Sections of Chapter 6 were revised to bring curb cut ramps up to date with the latest VDOT and ADA (Americans with Disabilities Act) requirements As mentioned in Chapter 3 sections dealing with traffic control, entrances, and geometrics were deleted from this Chapter 6, updated and inserted into Chapter 3 Renumbering of the remaining sections' titles were necessary CHAPTER 10 Wording was added to clarify the requirement that City roadway projects as well as private development must tie to the State Plane Coordinate System CHAPTER 11 Clarification was given to sections dealing with the requirements, procedures, and processes for "As-Built" survey drawings and plans for the City's records CHAPTER 12 Sections 12 4 and 12 5 were revised and expanded to protect the City's interest on the standards to be used for bulkheads, revetments, or other shoreline hardening structures along the oceanfront and the bayfront A correction was made to refer to Section 5B of the Site Plan Ordinance for floodplain issues CHAPTER 15. A correction was made to show that the Civil Inspections Bureau is no longer in Public Works CHAPTER 16 Sections were revised to update traffic control standards We are attempting to have emergency vehicle pre-emption equipment installed in all new traffic signals and to retrofit existing signals in the future, as resources permit APPENDIX B Several drawings in Appendix B, dealing with standard storm drainage structures, are included in the package Minor revisions were made to increase structural strength and to make the drawings more flexible to take advantage of available standard pre-cast concrete structures Also, new drawings for standard shallow structures were included to assist in reducing design costs for special structures used with many projects APPENDIX C Drawing C-7, CG-12 Curb Ramp was revised to bring it into compliance with City policy as well as state and federal ADA regulations The standard City Wakefield Bulkhead drawing is added to Appendix C along with a new drawing for concrete paver units when used specifically for sidewalks and pedestrian crosswalks within the roadway pavement APPENDIX D New drawings were added providing standard details for a recycled plastic decorative traffic sign post, and the telescoping steel traffic sign posts, which are referred to in Chapter 2 Other minor changes to the City standard median nose and entrance locations were made to improve safety APPENDIX E The standard traffic engineering general notes were updated AMENDMENT # 3 PUBLIC WORKS SPECIFICATIONS AND STANDARDS MANUAL MARCH 1997 Public Works Specifications and Standards TABLE OF CONTENTS FORWARD ................................................... xxviii INTliODUCTION Section 1.0 Intent 1-1 e.eeeeeeeeeeeeee..eeeeeee.eeeee.ee.e Section 1.1 Resolution of Conflicts 1-3 e.e................

SECTION 2.1 Storm 8ewers 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. Ail storm sewer pipes and culverts shall be installed in accordance with the Virginia Department of Transportation Road and Bridge Specifications, ~9 I994, ~, and the Virginia Department of Transportation Standards, (1993), drawings 107.01, 107.02, and 107.03. Ail storm sewer pipes and culverts installed in the right of way as well aw ~ubli~ ~a~ements, w~er~ve~pipes.may be subject to traffic loadings~ shall be backfilled with granular material placed in six (6) inch lifts and compacted to 95 percent of standard density based on AASHTO Specifications T-99 (ASTM D698). See Section 5.12 concerning the use of flowable fill in or around City storm sewers, ductile iron or cast iron water or sewer lines. However, if corrugated metal pipe is to be used the pipe must be asphalt coated. Revised 3/97 Materials Page 2 - 1 Public Works Specifications and Standards into the coarser materials under the action of hydraulic gradient from ground water flow. Where significant ground water flow is anticipated, avoid placing coarse, open graded materials, such as (crushed rock) Class IA, ASTM D2321 above, below, or adjacent to finer materials, unless methods are employed to impede migration. A filter fabric shall be used to separate the materials and stop migration of fine materials into the open graded material. SECTION 2.1.3 Inlet Shapinq Ail storm sewer drop inlets, catch basins, and manholes shall have full diameter invert shaping ~in accordance with. VDOT Standard IS-1. T~im. ~upport this ~usual SECTION 2.1.4 Minimum Drop Across Structures Whenever possible all storm sewer drop inlets, catch basins, and manholes shall be installed with the crown of the inlet pipe matching the crown of the outlet pipe, unless the inlet and outlet pipes are the same size, in which case the total drop between the inlet and outlet across the structure shall be no less than 0.1 foot, whenever possible. Variances to this may be addressed by the reviewing engineer, based on the acceptability of the hydraulic grade line calculations. SECTION 2.1.5 Weep Holes Ail storm drainage inlet structures in the right of way shall have a note or detail indicating that permanent weep holes be installed into drainage structures at the aggregate/subgrade interface. These weep holes shall remain open after completion of the construction by using hardware cloth (or an acceptable alternative as approved by the Civil Inspector) to prevent gravel intrusion into the drainage structure. Weep holes shall be constructed in accordance with City standard details ~ A~pen~iX B. SECTION 2.1.6 Marking Non-Concrete and Non-Metal Pipe Ail storm sewer pipe and culverts which are not concrete or metal shall have 3" white metallic marking tape placed above the pipe at an elevation no less than one (1) foot below the ground surface.

SECTION 2.2.3 Corrugated Aluminum Allo¥ Wall Thickness Revised 3/97 Materials Page 2 - 5 Public Works Specifications and Standards SECTION 3.12 Sight Distance SECTION 3.12.1 General The following standards in Seut~on 3~12 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.

SECTION 3.14.2 ~uardrail TvDe 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 justified by the designer/developer and will be considered on an individual basis by the City Engineer Or City TrafficEngineer. SECTION 3.14.3 ~uardrail 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 face of the W beam guardrail shall be vertically aligned six (6) inches behind the face of the curb. SECTION .3. t5 As-Built Drawings 1.

Accepting or requiring an escrow (or bond which serves this purpose) is a last resort and is discouraged because the value of the escrow amount decreases with time and obtaining the physical improvements is the primary objective. Escrows will be required where projects are in the C.I.P. regardless of pavement widening. An inflation factor should be applied to provide adequate cost when the improvements will be installed in the future. Sidewalk, curb and gutter, drainage ~ streetiights are a necessity whether a Capif~l Improvement Project exists or not. These improvements will not be waived except in unusual or impossible cases such as when sidewalks do not connect to other sidewalks or there are few in the area, or no adjacent piped storm drainage or curb and gutter; as justified, in writing, to the Director of Public Works. ~n _no ~se wll~ streetlighting be waive~. In addition, pavement widening is a safety requirement and upgrading road frontage (widening up to 3') to an existing street section may be necessary regardless of C.I.P. improvements and will not be waived unless in unusual or impossible cases. The widening does not entail additional lanes nor is traffic impact justification a necessity. Requiring additional lanes for construction shall be substantiated by traffic generation.

The improvements will: delineate public parking, improve public safety, and standardize private entrances. This section is applicable to the 100/200 blocks of 41st Street through 89th Street. C~ncral The city of Virginia Beach shall provide street improvements (as funding is made available) for the Virginia Beach property owners within the project area when all requirements stipulated in this SECTION are met. Public cost participation is required to help defray the expenses of design, administration, and construction of the project. .............. · ..... ~ ..... · ............. These definitions apply to this section as they pertain to North Virginia Beach Street Improvements. Aggregate - Hard, inert, mineral material used for mixing in graduated fragments. Includes sand, gravel, crushed stone, and slag. Alley - A public or private right-of-way usually designed to serve as secondary access to the side or rear of those properties whose principal frontage is on a street. Apron - A broadened part of an automobile driveway or parking pad, at where it joins the roadway. Asphalt - Dark brown to black cementitious material, solid, semisolid, or liquid in consistency, in which the predominant constituents are bitumens that either occur in nature or are obtained in the refining of petroleum. Asphalt Concrete - High-quality, thoroughly controlled hot mixture of asphalt cement and well-graded, high- quality aggregate, thoroughly compacted into a uniform dense mass. Bid - An offer to perform construction work for payment, the acceptance of which constitutes a contract between the city and the contractor. Block Captain - The representative designated by property Page 6 - 6 Incidental Concrete Construction Revised3/97 Public Works Specifications and Standards The following are guidelines which shall be adhered to during plan preparation. The numerical sequencing is only an aid and is not intended as a hierarchy or priority of significance. I · The roadway width shall be 36 feet when measured face-to-face between the curbs. The roadway cross section shall include curb and gutter (type CG-6). The roadway cross section is centered within the roadway right-of-way. A cul-de-sac is normally located at the end of the existing roadway and shall not extend into the dune line. A cul-de-sac shall have a minimum pavement radius of 35 feet. 6~. On street public parking is provided and maximized. The existing street lighting is evaluated. The resulting street lighting design plan shall meet all current City standards for residential illumination. Encroachments in the right-of-way such as landscaping and physical structures may be removed as necessary to accommodate construction. The property owner shall have adequate notice and opportunity to relocate the encroachments prior to the start of construction. The face of curb radii shall be a minimum of 35-feet at the intersection of the project street with Atlantic Avenue. The existing traffic control signing and pavement marking is evaluated. The City shall ensure the project design conforms to the current standards and requirements of the Manual on Uniform Traffic Control Devices Page 6 - 10 Incidental Concrete Construction Revised3/97 Public Works Specifications and Standards (MUTCD). The required installations shall conform to current Public Works/Traffic Engineering standards. 11. The pavement section will be constructed of asphaltic concrete designed for the existing soil conditions. 12. Existing exposed-aggregate finish driveway aprons and parking pads are replaced in-kind, unless in conflict with VDOT of ADA standards. All other aprons and pads are replaced with class A-3 concrete. If the property owner elects to upgrade the driveway or parking pad to an exposed aggregate finish, the property owner must pay the cost differential (exposed aggregate vs. A-3 concrete finish). This is a material standard; see item #13 below for geometric criteria. Each single-residential unit requires two parking spaces. Where adequate on-site parking exists or is required by the approved site plan, one 12-foot wide driveway is designed so as to tie into that parking area. Where on- site parking does not exist or is not required as part of the approved site plan, a 20-foot wide parking pad for two cars is designed within the right-of-way. For multi-residential units, each unit requires two parking spaces. Where adequate on-site parking exists or is required with the approved site plan, one 12-foot wide driveway is designed so as to tie into that parking area. Where on-site parking does not exist or is not required as part of the approved site plan, parking pads are designed within the right-of-way using the following widths: cars = 36 feet cars = 48 feet cars = 64 feet The width of the parking pad will not exceed the lot width. Any existing entrances and parking pads within the right-of-way shall be modified to meet the criteria set above. Refer to chart (Figure VI - 2, Entrance Detail). Revised 3/97 Incidental Concrete Construction Page 6 - 11 Public Works Specifications and Standards Whenever on-site parking is available or required as part of the approved site plan but does not provide the minimum required number of parking spaces, the City shall amend the parking pad widths described above by deducting for any parking which is provided or required by the approved site plan. The City will coordinate with the property owner to design the most practicable parking. For example: a single residential unit has no existing on-site parking but the approved site plan stipulated one space was required. The City will design a 12-foot wide driveway which shall extend through the full right-of-way for parking of one vehicle and the property owner shall provide a parking space as required by the approved site plan. The petitions used in this program are presented on page 6-17 of this manual. SECTtON~ 6.2 . 5 . General. The following procedures specify the necessary activities and their sequence for implementing the North Beach Street Cost Participation Program. See Figure VI - 1, Process Flow. a. Select a Block Captain: The property owners for each affected block must select an individual to represent them as Block Captain. The Block Captain will coordinate the activities of this program and serve as liaison with the City. The City will coordinate all activities of this SECTION through the Block Captain. be Petition for Preliminary Design: Petitions are circulated and collected by the Block Captain. Each separate parcel of property with frontage on the project street is allotted one vote for participation during the petition process. The preliminary design plan Page 6 - 12 Incidental Concrete Construction Revised3/97 Public Works Specifications and Standards approval to start of actual construction. If Council does not approve funding, the affected property owners will receive full refunds according to their actual paid cost participation amounts. This amount will include any contribution made towards the participation requirement for another property. · Standard Lots: Each separate parcel of property with frontage on the project street will pay the cost participation requirement stipulated in Figure VI - 2, Entrance Detail. · Cul de Sac: Where cul de sac improvements are proposed in the right of way, frontage shall be determined based on the right of way of the project street, i.e., the straight line distance from property line to property line along the right of way, regardless of the location of the cul de sac. The full criteria stipulated for cost participation in Figure VI - 2, Entrance Detail are applicable. · Corner Lots: If the property abutting a roadway intersection has a circular property line on the right of way being improved, the definition of "frontage" is modified. The frontage shall be determined by connecting the tangents of the circular property line (extending two straight property lines to form a corner) and then measuring from this point of connection to the opposite property line corner on the project street. 4. Alleys: a· Private: Only the property owner having frontage along the project street will have a vote for participation.
