Flood Depth and Analysis Grids
• Grids include: – Flood Depths for multiple flood frequencies
– Water Surface Elevation for multiple flood frequencies
– Water Surface Elevation Change Since Last FIRM (1%)
– Percent Annual and 30-yr Percent Chance of Flooding
– Velocity
– Hillshade

Areas of Mitigation Interest
Mapping a Coastal Floodplain
Coastal Flood Hazard Zones
– VE Zone – Areas expected to be affected by waves 3 feet and higher in the 1% chance storm
• Base Flood Elevation established – AE Zone – Areas expected to be flooded by waves of
less than 3 feet in the 1% chance storm • Base Flood Elevation established
– LiMWA – Limit of Moderate Wave Action, where the wave height is 1.5 feet. The area between the LiMWA and the VE zone is the Coastal A zone
• Non-Regulatory – X Zones – Areas not expected to be flooded in 1%
chance storm • Shaded X – Areas expected to be flooded in 0.2% chance event • Base Flood Elevations not established
Limit of
Moderate Wave Action (LiMWA) FEMA Procedure Memorandum No. 50, 2008
• No federal regulatory requirement
• No federal insurance requirements tied to LiMWA
Study Findings: •Recurrent flooding is a significant issue and risk in coastal Virginia and is predicted to worsen •A variety of adaptive strategies are feasible and appropriate •It takes 20 to 30 years to plan & implement an effective response strategy

RECOMMENDATIONS TO THE SECURE COMMONWEALTH PANEL ON THE ISSUE OF SEA LEVEL RISE AND RECURRENT FLOODING
IN COASTAL VIRGINIA
SUBMITTED TO THE HONORABLE BRIAN MORAN
SECRETARY, PUBLIC SAFETY AND HOMELAND SECURITY CHAIR, SECURE COMMONWEALTH PANEL

Select Recommendations from the Report
• Consider modification to Real Estate disclosures to include flood-related damages
• Reassess FEMA Special Flood Hazard Areas
• Collect and maintain LiDAR in conjunction with NOAA and other federal agencies.
• Use the U.S. Army Corps of Engineer Silver Jackets program and the Virginia Sea Grant to coordinate agencies.
