Georgia Flood Risk Mapping Assessment and Planning MAP

Georgia Flood Risk Mapping Assessment and Planning (MAP) Program Southwest Georgia Regional Commission March 28, 2019 Haydn Blaize, Manager, Floodplain Unit

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

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

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) • Food Risk Zones • Base Flood Elevations for Detailed Studies – water surface elevation during passage of the 1% annual chance flood 4

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

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

JOINING THE NFIP Participation in the National Flood Insurance Program (NFIP) is voluntary. To join, the community must: • Complete an application; • Adopt a resolution of intent to participate and cooperate with FEMA; • Adopt and submit a floodplain management ordinance that meets or exceeds the minimum NFIP criteria. The floodplain management ordinance must also adopt any FIRM or FHBM for the community. 16

Community Rating System • Voluntary incentive program • Encourages community floodplain management activities that exceed the minimum NFIP requirements. • Will reduce flood insurance premium rates 17

Base Level Engineering (BLE) • Base Level Engineering (BLE) is an approach that combines high resolution ground elevation data and automated modeling technology advancements to create engineering models and flood hazard data typically at a large scale, like a watershed. • GAEPD proposes to undertake BLE studies on 11, 150 stream miles in 47 watersheds (Subject to FEMA Approval and Funding). 25
