ADD ON
Mayor Sessoms, along with the entire City Council, offered condolences to Council Lady Wilson at the
untimely passing of her brother-in-law. He was on vacation in Peru. The family is working to get his
body back to the United States.
On a positive note, Council Lady Wilson is on her way to New York as her daughter is in labor.
As such, Council Lady Wilson and Councilman Wood are unavailable to attend the Retreat scheduled for
Friday, September 6`". In addition, there is a good chance Councilmen Davis and DeSteph may no longer
be serving as City Council representative so it is the Mayor's suggestion to cancel the upcoming Retreat.
City Council consented.

The adaptation strategies below are for recurrent flooding:
N
Recurrent Flooding - ,
Adaptation Strategies` °'• --.-
• Management/Retreat
— Prevent development in high risk areas
— Discourage rebuilding in high risk areas
• Accommodation
— Elevating buildings/Flood proofing homes
— Evacuation routes/warning systems
• Protection Measures
— Focus of Today's Discussion
• Interim
• Comprehensive 19
The Adaptation Strategy of Protection Measures is the basis of today's discussion. Protection Measures
are complex and costly; and, most importantly, there is a limit to their effectiveness:

— Limit to Effectiveness (LOS)
• LOS Exceedence = Major Flooding

New Orleans has 130 miles offloodwalls, levees and dikes, with over seventy (70) major pump stations.
Each of the waterways in and out of the city has a major storm surge barrier, and yet all of the protective
measures were not enough to stop the flooding of Hurricane Katrina:

The Stormwater CIP included Eastern Shore Drive Drainage Improvement, partially funded through
FY2017. The funded amount of$54-Million with the final costs is likely to be significantly higher. The
Project Development Study is underway:
Comprehensive Flood Control Measures
Major CIP: 7-151 Eastern Shore Drive
Drainage Improvement
Programmed Funding: $53.13 M
Final Cost: TBD
Project Development Study Underway
• Identifying Improvements: Large Collection
Pipes, Pump Stations, Outfalls, Flood Control
Gates, Flood Walls
• Structures in Lowest Lying Areas Will Likely Need
To Be Elevated
• Developing Phased Implementation Plan
• Draft Study Results By End of Year 23
The Interim Flood Control Measures below are currently in place:
Interim Flood Control Measures
• Following the Nor'Ida in 2009, requests for flood
control became more frequent
• Some have suggested installing backflow preventers
to keep tides out
• Inflatable Temporary Devices—Trial Basis
• Requires Accurate Prediction of Tides and Rain
• Reliance on Human Performance for Inflation and
Deflation of Devices
• Safety Concerns for Personnel
• Once in Place, Cannot Be Adjusted During Storm
• Have Potential To Worsen Flooding
• Inflatable Devices Are Not Automated

The automated devices can overcome many of the operational issues of inflatable temporary devices;
however, they have the potential to worsen flooding:

Interim Flood Control Measures
Detailed analysis:
• Determine where backflow prevention devices
will help reduce flooding from high tides
• Determine where backflow prevention devices
will not increase flooding from rainfall
• Determine type of backflow prevention device
appropriate for location (flexible check valve
or automated sluice gate)
27
The City identified thirty-nine (39) locations to be considered for installing these automated devices:
Interim Flood Control Measures
39 Locations Considered
For Each Location Evaluated:
• Determined tidal elevation at which flooding will
occur, even with backflow preventer in place
• Determined elevations of streets and homes
• Calculated available storage for rainfall in each
drainage basin
• Hydraulically modeled numerous rainfall /tidal
elevation combinations to determine benefits and
impacts of installing backflow prevention devices

some benefit:

Summary of Findings
• In eight locations backflow prevention devices can
provide limited benefit by reducing the frequency of
flooding from certain high tide /rainfall combinations
• Greatest benefits are associated with relatively low
probability events(High Tide, Low Rain)
• Backflow prevention devices cannot eliminate all
flooding
• There have been at least three storms since 2009 for
which the backflow preventers would have had
absolutely no benefit:
— Nor'Ida(November 2009) Elev.6.9'
— Irene(August 2011) Elev. 5.5'
— Sandy(October 2013) Elev.5.7' 36
All elevations are In NAVD 88 datum.
