Flood Insurance Rate Maps & Flood Insurance Study Notice

The United States Department of Homeland Security’s Federal Emergency Management Agency (FEMA) is in the process of producing new preliminary Flood Insurance Rate Maps (FIRM) and Flood Insurance Study (FIS) for Dallas County as this includes the City of Lancaster; see link below for this letter.  A FIRM is a map that shows the 100-year floodplain as this affects properties near existing City creeks.  The FIS is a study that compiles and presents the flood hazards along existing streams, creeks and lakes within a community.  The last official FIRMs and FIS for the City of Lancaster was done on July 7, 2014.  A comparison of the preliminary and existing (July 7, 2014) FIRM is available in the link below.

The 90-day public review period begins August 1, 2021 and ends October 31, 2021.  If your property is currently mapped within the preliminary FIRM of this 100-year floodplain and you have scientific evidence that FEMA’s mapping is incorrect, there is an appeal process that must be submitted directly to FEMA.  After this 90-day public review period, FEMA will start the process of finalizing the FIRMs and FIS.  A hard copy of the FIRMs and FIS are located within a white binder located at the Development Services, 700 East Main Street, Lancaster, Texas 75146. Citizens may also access these documents in the links below.
