Date Aug 2011 of June 2012 Dec Work Map Meeting was held in May 2011

5 Study Update Methodologies Levels of Study Coastal Analysis Physical Map Revision (PMR) Area studied: Long Island Sound

6 Data Used for Coastal Analysis Topographic data collected during 2007 Connecticut Light Detection And Ranging (LiDAR) mission 2-ft contours were used for mapping Appendix D (2003) of the Guidelines and Specifications and Atlantic and Gulf Coast Update (2007)

7 LiDAR Coverage

8 Detailed Study Coastal Analysis Coastal analysis - includes 4 main components: Stillwater Level (storm surge) + Wave Set-up Overland Wave Propagation Wave Runup and Overtopping Primary Frontal Dune

9 Detailed Study Stillwater Level (SWEL) Return period gage analysis Linear interpolation between gage points Pool elevation

10 Detailed Study Wave Setup Numerically determined at each coastal transect Determining factors Average nearshore slope [depth of wave breaking to SWEL] Deepwater significant wave height SWEL + Wave Setup = Total Water Level (TWL) Areas where floodplain is restrictive, wave setup is removed and SWEL is mapped Constrictions such as low bridges Narrowing of the floodplain

11 Detailed Study Overland Wave Propagation Includes Wave Generation on Inland Water Bodies

12 Detailed Study Runup and Overtopping

13 Detailed Study Primary Frontal Dunes

14 Detailed Study Summary Significant Changes from previous study: Includes Wave Set-up Includes Wave Generation other than offshore waves Includes 2% Wave Runup Includes Primary Frontal Dune

15 Limit of Moderate Wave Action LiMWA Areas subject to wave heights greater than 1.5 feet Defines Coastal A Zone Recommendation of building to V zone standards Currently nonregulatory in Connecticut

16 Flood Risk Products - Background In 2010, FEMA funded creation of flood risk products for the 2009 studies These products are intended to help communities better understand and communicate flood risk GIS data such as parcels and building footprints were requested from the communities by STARR to be included in these products

17 Flood Risk Products - Background The following flood risk products were created for this study Changes Since Last FIRM (CSLF) Wave Height Grids Contributing Engineering Factors

18 Flood Risk Products Changes Since Last FIRM SFHA Decrease SFHA Increase

19 Flood Risk Products Wave Height Grids Wave Height Grids Provided for 1% annual chance floods

20 Flood Risk Products Contributing Engineering Factors Provide insight into the factors behind the increase or decrease in the flood hazard areas Can prove to be useful for planning and mitigation measures

23 Discover the Coastal Communities Understand local interest, issues, capabilities of communities Status of Mitigation Plan Communication desire, skills, resources Interest in and resources for mitigation Experience with flood disasters and recovery Floodplain administration Interest in cost-share Mitigation support needs and interests

24 Middlesex County Coastal Community Mitigation Plan Status Community Plan Expiration Date RPA Name (Multi) Plan Status t Clinton 1/18/2012 CRERPA Approved Fenwick 1/18/2012 CRERPA Included in the Old Saybrook Mitigation Plan Old Saybrook 1/18/2012 CRERPA Approved Westbrook 1/18/2012 CRERPA Approved

25 Discover FEMA Programs Flood Mitigation Assistance annual funding to reduce risk to NFIPinsured structures Hazard Mitigation Grant Program declared disaster funding for longterm hazard mitigation measures Pre-Disaster Mitigation Program annual funding for hazard mitigation planning and implementation Repetitive Flood Claims - annual funding to reduce risk to NFIP-insured structures with one or more claims Severe Repetitive Loss annual funding to reduce risk to NFIP-insured severe repetitive loss structures Community Rating System proactive communities receive insurance discounts for residents

26 POST-PRELIMINARY PRELIMINARY PROCESSING

27 Post-Preliminary Preliminary Phase Timeline Typical Post Preliminary Phase takes approximately 14 months to complete E Sept 22, 201 Nov 9, 2011 Est. Dec days Est. Dec days st. Mar Es st. June months Est. Dec Review and Appeal Period Compliance Period

28 Community Review 90-day Public Review and Appeal Period Appeals versus Protests/Comments Appeals The sole basis of appeal shall be the possession of knowledge or information indicating that the elevations proposed by FEMA are scientifically or technically incorrect. Protest or Comments Road or flooding source name change, changes to corporate limits, i etc. Changes to flood hazard delineations due to more detailed topographic p (elevation) information

29 Post-Preliminary Preliminary Processing Communities with new or modified Base Flood Elevations Town of Clinton Town of Old Saybrook Town of Westbrook Borough of Fenwick NOTE: All communities may review and submit comments during the 90-day time period

30 MYTHS! The 90- day appeal/protest p period is my only chance to change FEMA s maps? NO What are my other options? Letter of Map Amendments (LOMA): A request to FEMA for removal of individual properties p or structures from the SFHA Letter of Map Revisions (LOMR): A request to FEMA to modify an effective Flood Insurance Rate Map (FIRM), or Flood Boundary and Floodway Map (FBFM), or both. Results in the modification of the floodway, BFEs, or the Special Flood Hazard Area (SFHA).

31 Post-Preliminary Preliminary Processing Summary of Map Actions (SOMA) Background Letters of Map Change (LOMCs) are legally binding changes to the map Many LOMCs (such as Letters of Map Amendment) are not typically y reflected in the new FEMA maps due to scale constraints Some LOMCs are superseded when a new map is issued Summary of Map Actions is an assessment of all existing LOMCs compared with the new FEMA maps

32 Summary of Map Actions Category 1: shown on the new DFIRM panel Category 2: NOT shown on the new DFIRM panel due to scale limitations (revalidated after the new DFIRMs become effective)

33 Summary of Map Actions (continued) Category 3: superseded, and no longer valid, due to revised flood hazards Category 4: property owner must request this be re-determined

34 Post-Preliminary Preliminary Processing Revalidation of Letters of Map Change (LOMCs) The Summary of Map Actions (SOMA) is used to generate a Revalidation Letter The Revalidation Letter is issued to the community Community officials are encouraged to disseminate this information.

35 Post-Preliminary Preliminary Processing Revalidation Letter Distribution Community FEMA Regional Office NFIP State Coordinator LOMC Compendium NOT to Homeowners or Developers IS available through Map Service Center:

36 Post-Preliminary Preliminary Processing The compliance and map adoption period begins at the date the Letter of Final Determination is sent, and ends at the effective date. During the compliance and map adoption period, community officials review and, if appropriate, revise the community s floodplain ordinances to ensure they are compliant with NFIP regulations. Important! To avoid suspension from the NFIP, the community must adopt a compliant floodplain management ordinance and submit its ordinance to the FEMA Regional office (through the NFIP State Coordinator s Office) for approval prior to the end of the compliance and map adoption period.
