Flood Map Modernization
A critical component of the National Flood Insurance Program is the accurate and most up to date mapping of the floodplains.

Important changes will be effective on September 26, 2014.

On March 29, 2013, Preliminary Digital Flood Insurance Rate Maps (DFIRMs) were provided to the County and municipalities by the Federal Emergency Management Agency (FEMA) for review.  These Preliminary DFIRMs are available for viewing and a Flood Map Viewer  has been developed to assist in locating property on the Preliminary DFIRMs.  A Summary of Map Actions is also available provides the status of all Letters of Map Amendment upon adoption of the revised maps.

On June 26, 2013 a Preliminary DFIRM Community Coordination Meeting with FEMA and the staff of the County and municipalities was conducted followed by many Community Outreach Open Houses.
 
On October 2, 2013, FEMA advised that the Comment and Appeal Period for the new DFIRMs would begin on October 16, 2013 and end on January 14, 2014.  The period ended with only comments being received.

On March 26, 2014, FEMA issued the Letter of Final Determination (LFD) for unincorporated Pasco County and the municipalities.  The LFD advised the County that prior to September 26, 2014, as a condition of continued eligibility in the National Flood Insurance Program (NFIP), the County must adopt or update their floodplain management regulations to comply with the standards of the NFIP regulations.  The mandatory revisions to the County ordinances were adopted on August 19, 2014 and the new, modern Digital Flood Insurance Rate Maps (DFIRMs) will become effective on September 26, 2014.
