New  2019 Preliminary Coastal Flood Maps

PHOTO 1 RGB

This preliminary data has been presented by FEMA as the best information available at this time and includes new or revised Flood Insurance Rate Maps (FIRMs), Flood Insurance Study (FIS) reports and FIRM Databases.  This release provides community officials, the public, and other stakeholders with their first view of the current flood hazards, which include changes that may have occurred in the flood hazards and risks throughout the County since the last flood hazard map was published in 2012.

Flood hazards and associated risks can change over time and water flow and drainage patterns can change dramatically because of surface erosion, land use, and natural forces. Thus, preliminary flood hazard maps help inform public officials, floodplain managers, industry stakeholders, and the public about how the community’s flood hazards and risks have changed.

Study Overview

In Fiscal Year 2013, the Federal Emergency Management Agency (FEMA) initiated a coastal flood risk study for the Southwest Florida Study Area that affects Charlotte, Collier, Desoto, Hendry, Lee, and Sarasota Counties. The results of that study will be incorporated into updated digital Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) reports for these counties.

 Preliminary National Flood Hazard Layer

  • The Flood Map Changes Viewer (FMCV) is the best way to view the Preliminary National Flood Hazard Layer and Preliminary Changes Since Last FIRM (CSLF) data in a map. The Preliminary CSLF view provides a visual of proposed changes to flood extents or proposed changes to zone designations for a location. The FMCV features the Preliminary Map Comparison Tool through which you may print a report featuring a side by side comparison of effective data and preliminary data a selected location.

    Preliminary Map Comparison Tool (PMCT): The PMCT allows customers to see Effective and Preliminary maps overlaid on one another. With this tool, users can view the latest hazard information overlaid with the existing information and save or print a report detailing the changes between these two data sets side-by-side for a single point of reference. A tutorial is available to provide additional information on how to use the Preliminary Map Comparison Tool.
