Flood Zone Maps

The City of Longwood, Seminole County, the State of Florida Department of Community Affairs (DCA), and the Federal Emergency Management Agency (FEMA) have partnered together to revise and update the 1995 Flood Insurance Rate Maps (FIRM). FEMA’s map modernization program entails providing updated flood maps and data for communities nationwide that are more accurate, easier-to-use, and readily available.


The City of Longwood, in partnership with our stormwater engineering consultants, performed a Conditions Analysis and Stormwater Modeling study as part of the City of Longwood’s Stormwater Master Plan.  The study resulted in updates to the predicted flood hazard zones. These are based on detailed parameters and regional drainage characteristics specific to the City of Longwood and contributing drainage basins. Currently, the results of the existing study and the predicted flood hazard zone limits have not been formally adopted by FEMA, however, the updated predicted flood hazard zones have been officially adopted by the City Commission and may supersede FEMA information at the discretion of the city engineers for the purposes of planning and engineering documents prepared for the City in the course of development review.

The Longwood Predicted Flood Hazard Zone Maps provide access to maps showing the predicted flood hazard zones from the City of Longwood study as well as an overlay of the predicted flood hazard zones compared to FEMA flood zones. The City of Longwood predicted flood hazard maps should be consulted as part of the due diligence phase when considering leasing or purchasing property in the city limits.
