The Regional Evacuation Study for South Florida (, completed in December 2010, used Sea, Lake and Overland Surge from Hurricanes (SLOSH) data from the National Hurricane Center, along with a digital elevation model, to produce the Storm Tide Atlas (Volume 7-11), which identifies the areas of the region that are projected to be under water in a Category 1 storm event. This study should be used as the basis for meeting the requirements of House Bill 1359, which amended Section 163.3178 (Coastal Management) in the Florida State Statutes, calling for a redesignation of the Coastal High Hazard Area (CHHA) as “the area below the elevation of the Category 1 storm surge line as established by the SLOSH computerized storm surge model.”  Local governments are required to amend their future land use map and coastal management elements to reflect the new definition of the Coastal High Hazard Area and depict it on the map.  The South Florida Regional Planning Council (SFRPC) did not produce a shapefile of the Coastal High Hazard Areas in the region as part of the Regional Evacuation Study for South Florida .  Instead, we have posted below links to the GIS shapefiles for a Category 1 Storm used to prepare the Storm Tide Atlas for each of the counties in South Florida – it will be up to each jurisdiction to review the data and determine the Coastal High Hazard Area for their jurisdiction in fulfillment of statutory requirements.
