How Mesquite came to be in the NFIP:

The City of Mesquite made application to enter the National Flood Insurance Program (NFIP) in the mid-1970’s. The hydrologic and hydraulic analyses for the flood study maps were completed by the Corps of Engineers in May 1978 and the Federal Emergency Management Agency (FEMA) adopted the maps June 4, 1980 making them the “effective” floodplain maps.

The City of Mesquite became a member of the National Flood Insurance Program (NFIP) in the late 1970’s. The NFIP establishes a self funded program to provide federally backed flood insurance to residents in communities that are a part of the program Federal NFIP regulations require the City review all new development in the floodplain to ensure it meets guidelines set forth by the Federal Emergency Management Agency (FEMA). City floodplain and drainage regulations are stricter than federal NFIP regulations to ensure residents are protected. City participation in the NFIP is also a condition for many federal grant and disaster aid programs.

Portions of the maps have been revised since their initial adoption to account for development activities in the floodplain and bridge and flood control improvements; however the base hydrology and hydraulic models and the underlying topography were not updated until the development of the new DFIRM mapping that in the process of being adopted.
