The North Carolina Floodplain Mapping Program (NCFMP) has revised the Chatham County Floodplain Maps based on appeals and comments received during the appeal period which ended January 12, 2015. NCFMP is now working with FEMA to finalize the maps for final release. No timeline has been given for the final release. 


The North Carolina Floodplain Mapping Program (NCFMP) in coordination with Federal Emergency Management Agency (FEMA) has issued preliminary Flood Insurance Rate Maps (FIRM) for Chatham County. These revised maps will replace the 2006 maps that are currently effective.

View the FIRM maps. To view the changes in the Chatham County maps since the last FIRM was published, on the website, toggle between the Effective and Preliminary FIRM and then turn on the “Changes since last FIRM” layer. There is a color coded map legend that provides information on the maps.
