*Click here for the current FEMA Flood Maps (dated 2/18/2005) Note: FEMA is no longer printing paper flood maps.

The City is expecting new - as yet unseen - flood maps to become effective sometime late-2019 to early 2020.

Historical Flood Maps & Flood Insurance Studies:

Notes: The older the original flood maps are, the harder they are to read. We've digitalized these older map sets and remastered them to be easier to read. However, these remastered versions are only approximate. When viewing buildings close to a flood boundary line, it'd be best to reference the original flood panel maps also listed below. 

Accessing these flood maps from the past will become more necessary as the release of new flood maps nears. Early indicators are to expect these new flood maps during the spring of 2021; longer if the City decides to mount appeals.

If FEMA's proposed maps do become effective, hat a number of buildings presently not required to maintain flood insurance – currently located within an “X” type flood zone – may need to obtain flood insurance for the first time, as those “X” zones are scheduled to shrink. Some 2,000 building presently in an "X" type flood zone will be remapped into "AE" type zones. (View the proposed new flood maps.)

Property owners may need to demonstrate structures built after December 31, 1974 were constructed to the flood zones and elevations existing at the time. Using the City’s GIS web site, the year of construction can be matched-up to the flood map in effect at the time (Use the most recent flood map dated prior to a permit for construction).

Major flood map changes occurred between the 1976, 1983, 1989 & 1997. Relatively minor changes occurred with the 1997 & 2005 maps.

Flood Insurance Study (FIS) Every community participating in the National Flood Insurance Program (NFIP) has an initial Flood Insurance Study that provides a detailed analysis of a community's flood risks.  This publication is usually only of interest to hydraulic engineers.

  * Prior to the establishment of an official Flood Hazard Rate Map (FIRM), the NFIP issued this Flood Hazard Boundary Map (FHBM) on June 15, 1973. This early map didn't have any identified flood zones nor Base Flood Elevation (BFE) levels within the City of Key West. (The flood zones and BFEs shown on this map are outside the city limits. 

Under this map, the entire City was considered an "Approximate A Zone." As such, the minimum elevation standard was +two-feet above grade.

The first FIRM with identified flood zones and BFEs was issued about a year later on July 1. 1974. (Reflected on revised maps dated Oct. 29, 1976).
