National Flood Insurance Program

Nashville participates in the National Flood Insurance Program (NFIP) administered by the Federal Emergency Management Agency (FEMA), which aims to reduce the impact of flooding on private and public structures. For this program, Flood Insurance Rate Maps (FIRMs) produced by FEMA are used to determine each property's flood hazard. The current flood maps are searchable on FEMA's website.

Beginning April of 2017, new maps produced by FEMA that include previously un-mapped areas become effective. For more information on these changes, view our New Flood Map Fact Sheet.

Assistance for residents

If you are a resident in Davidson County whose property is included within the newly mapped 100-year floodplain or floodway, you should have received a 100-year floodplain resident letter. For those residents, we will be holding an Open House on November 7 and an Open House on November 8 to view these changes and answer questions.

Assistance for lenders, realtors, and insurance agents

Metro Water Services can provide assistance with flood insurance forms and interpreting flood insurance rate maps. Download our National Flood Insurance Program flyer for more information.
