  1. WATERSHED FLOOD MAPSApalacheeBay – St. Marks River Basin Resources Flood Maps

  2. WATERSHED FLOOD MAPS APALACHEE BAY – ST. MARKS RIVER WATERSHED AERIAL • Base map for the development of flood maps • Helps understand the water resource

  3. WATERSHED FLOOD MAPS POPULATION2010 CensusTotal Basin Population353,476 MAP IN PRODUCTION

  4. LAND USE WATERSHED FLOOD MAPS Total Basin Size (NWFWMD) = 543 sq. mi. [Forest/Wetlands = 790 sq. mi. (76%)]

  5. WETLANDS WATERSHED FLOOD MAPS • 325 sq. mi. of wetlands in the basin • Help attenuate flood flows • Provide a significant amount of flood storage • NWFWMD ERP provides wetland protection & mitigation • NWFWMD dam safety regulatory program

  6. CONSERVATION LANDS WATERSHED FLOOD MAPS • Most are within the Apalachicola National Forest & the St. Marks Wildlife Refuge • Along with public preservation and recreation opportunities, conservation lands are a preventive measure that helps keep development out of the flood zone.

  7. WATERSHED FLOOD MAPS GAGE LOCATIONS MAP IN PRODUCTION • Existing gages • Useful for flood warning and flood study model calibration

  8. LiDAR DATA WATERSHED FLOOD MAPS • NWFWMD LiDAR data base • DEM for entire basin • Important base data that is used throughout the district for flood mapping

  9. SPECIAL FLOOD HAZARD AREA(SFHA) WATERSHED FLOOD MAPS

  10. WATERSHED FLOOD MAPS Escambia CountySFHA w/ Panel Scheme MAP IN PRODUCTION • Map Modernization – upgraded maps in Escambia County • Maps revised and went effective on September 29, 2006

  11. WATERSHED FLOOD MAPS Santa Rosa CountySFHA with Panel Scheme MAP IN PRODUCTION • Map Modernization – upgraded maps in Santa Rosa County • Maps revised and went effective on September 29, 2006

  12. WATERSHED FLOOD MAPS Okaloosa County SFHA with Panel Scheme MAP IN PRODUCTION • Map Modernization – upgraded maps in Okaloosa County – Effective = December 6, 2002 • Now we are working under the risk map program to further improve the flood maps.
