1. US Army Engineer Research and Development Center COASTAL OUTREACH ADVISORY TEAM Kick-off Meeting November 19, 2010 FEMA Region III Coastal Mapping Project

2. US Army Engineer Research and Development Center Today’s Agenda Map Modernization to Risk MAP Region III Coastal Study Preliminary DFIRM schedules Outreach Coastal Outreach Advisory Team (COAT) Questions/Discussion

3. US Army Engineer Research and Development Center Map Mod to Risk MAP Nationwide, 5-year, $1 billion program Updated FEMA’s Flood Insurance Rate Maps (FIRMs): 70 percent were over 15 years old Produced seamless digital flood data on a countywide basis Reduced map production time Reduced cost/time for future updates

4. US Army Engineer Research and Development Center New digital FIRMs more accurately represent current flood risk Countywide DFIRMS – easier to use and update Map Mod to Risk MAP

5. US Army Engineer Research and Development Center Risk Mapping, Assessment and Planning, or Risk MAP: 2010- 2014 Builds on Map Mod successes Will deliver quality data that increases public awareness and leads to action that reduces risk to life and property. Watershed approach Coastal re-mapping Stronger communication support Map Mod to Risk MAP

6. US Army Engineer Research and Development Center Why a Region III Coastal Study Project Coastal flood risk information is out-of-date New Coastal Guidelines need to be implemented Update base data such as topographic dataset and aerial imagery to high resolution products and seamless Digital Elevation Model (DEM) Use newer proven coastal hazard methodologies developed during the FEMA Mississippi Coastal Restudy

7. US Army Engineer Research and Development Center Why a Region III Coastal Study Project Take advantage of higher performance numerical modeling Take advantage of improvement in GIS technologies to allow for more accurate FIRMs

8. US Army Engineer Research and Development Center Where Will the Study Occur? All of Region III coastal counties/cities (Atlantic Ocean Chesapeake Bay, Delaware Bay and their tributaries)

9. US Army Engineer Research and Development Center Coastal Study Process TERRAIN PROCESSINGSTORM SURGE ANALYSIS STARTING WAVE CONDITION ANALYSIS FIELD RECONNAISSANCEFRONTAL DUNE DELINEATION

10. US Army Engineer Research and Development Center Base Flood Elevation on FIRM includes 4 components: 1. Storm surge stillwater elevation (SWEL) 2. Amount of wave setup 3. Wave height above storm surge (stillwater) elevation 4. Wave runup above storm surge elevation (where present) Basic Elements of a Coastal Floodplain Study

11. US Army Engineer Research and Development Center Region III Storm Surge Modeling Current stillwater elevations (SWELs) on FIRMs date back 25-35 years SWELs will be updated for 50 coastal counties covering approx. 2280 miles of shoreline State-of-the art modeling setup by using ADCIRC soft coupled with the 2D wave model SWAN

12. US Army Engineer Research and Development Center Region III Storm Surge Modeling (cont’d) Obtain updated 10%, 2%, 1% and 0.2% annual chance stillwater elevations, wave setup and wave conditions for nearshore open-coast and back-bay shorelines Model results validated Being performed by USACE; due Spring 2011

13. US Army Engineer Research and Development Center Coastal Hazard Analyses Components Transect layout Field Reconnaissance (land use, obstructions, shoreline conditions, structures) Starting wave conditions (wave height and period) from 2D wave modeling

14. US Army Engineer Research and Development Center Coastal Hazard Analyses Components Erosion analysis Development of a seamless Digital Elevation Model Overland wave height computation (using WHAFIS) Wave Runup

15. US Army Engineer Research and Development Center Elements of a Coastal Floodplain

16. US Army Engineer Research and Development Center Something New – LiMWA Limit of Moderate Wave Action FEMA Procedure Memorandum No. 50, 2008 At present, not a regulatory requirement No Federal Insurance requirements tied to LiMWA CRS benefit for communities requiring VE Zone construction standards in areas defined by LiMWA or areas subject to waves greater then 1.5 ft

17. US Army Engineer Research and Development Center Region III Coastal Study Timeline Surge Study Results Spring 2011 Surge Study Results Spring 2011 Coastal Hazard Analysis Results Summer 2011-Fall 2012 Coastal Hazard Analysis Results Summer 2011-Fall 2012 Preliminary DFIRMs Winter 2011 – Spring 2013 Preliminary DFIRMs Winter 2011 – Spring 2013 Public Comment Period Winter 2011– Spring 2013 Public Comment Period Winter 2011– Spring 2013 Letter of Final Determinati on Fall 2012– Winter 2013 Letter of Final Determinati on Fall 2012– Winter 2013 New Effective Coastal DFIRMs Spring 2013 – Summer 2014 New Effective Coastal DFIRMs Spring 2013 – Summer 2014

18. US Army Engineer Research and Development Center OUTREACH

19. US Army Engineer Research and Development Center Outreach is Critical Goal: Maximize public and private sector awareness of and engagement in the flood study process Increase public awareness and understanding of risk and vulnerability to floods plus options for minimizing their risk; Keep citizens, public officials and stakeholders informed; Increase engagement of county and city elected officials; Foster stakeholder awareness Provide communities with outreach tools

20. US Army Engineer Research and Development Center Multiple Sources Outreach must be constant and consistent to all Internal (“In-Reach”) Elected Officials City/County Managers & staff Stakeholders Local industry; Interest Groups Chamber, Civic organizations Media Local newspaper, radio Public Open House, Library Local Government TV & website Homeowner Association Meetings

21. US Army Engineer Research and Development Center Coastal Study Outreach Support Coastal Outreach Strategy Website – www.r3coastal.com Outreach factsheets Outreach meetings Initial outreach (scoping) meetings for each county/city Regional technical storm surge study meetings Flood study review meetings for some counties/cities Final community meetings for each county/city Open houses for some counties/cities Stakeholder Meetings – COAT

22. US Army Engineer Research and Development Center Coastal Outreach Advisory Team Your Role is Important Share local data or new information Relate study information and status to other stakeholders Provide input on outreach methods, target groups, etc. Identify potential contentious issues Provide input on coastal study methodology

23. US Army Engineer Research and Development Center Coastal Outreach Advisory Team Meeting Frequency & Content Every other month or as needed One hour in length Typical Agenda Study status and outreach update Request updates (e.g., outreach, new studies, issues) from team members Share any new outreach material; ask for feedback Discuss any changes to methodology of coastal analysis; ask for feedback Identify other possible members that should be invited

24. US Army Engineer Research and Development Center New Coastal Study Results Mean… More accurate picture of our coastal flood risks Better, more comprehensive planning for economic development, mitigation & emergency response Better tools to manage flood risks, land-use, water resources, disaster recovery & other responsibilities more effectively Safer building practices based on current risk information More informed financial decisions by residents and business owners who understand their flood risk and apply their knowledge to financially protect their home or business

25. US Army Engineer Research and Development Center Questions/Discussion
