  1. Georgia Flood Risk Mapping Assessment and Planning (MAP) Program Heart of Georgia Altamaha Regional Commission June 27, 2019 Haydn Blaize, Manager, Floodplain Unit

  2. Role of State • The State of Georgia entered into a Cooperating Technical Partner (CTP) agreement with FEMA’s Region IV in August 1999. • State of Georgia now develops and updates the flood hazard maps for communities in all 159 counties https://msc.fema.gov/portal/home 2

  3. Role of State Cont’d The Floodplain Unit provides community outreach and assistance through a structured Community Assistance Program State Support Services Element (CAP SSSE) 3

  4. Regulatory Products • DIGITAL FLOOD INSURANCE RATE MAP (DFIRM) • Delineates the Special Flood Hazard Area (area inundated by the 1% annual chance flood often referred to as the 100-year flood) • Flood Risk Zones • Base Flood Elevations for Detailed Studies – water surface elevation during passage of the 1% annual chance flood 4

  7. Role of Community • State and local governments are required to enforce floodplain management ordinances • Residents and business owners with buildings in SFHAs required to purchase flood insurance • Not in the SFHA ? – ALL can purchase flood insurance • Close to 35% of claims are from properties NOT in a SFHA 7

  8. Role of Community (Cont’d) • A community that does not participate in the NFIP faces the following challenges: • Flood insurance not available through the NFIP • No federal flood related grants or loans available • No federal flood related disaster assistance available • No federal mortgage insurance or loan guarantees provided 8
