Flood Insurance Study (FIS) for Lee County

Since the first Flood Insurance Rate Maps were adopted in Lee County in 1984, FEMA has occasionally updated portions of the maps. Effective August 28, 2008, Lee County adopted the first comprehensive update affecting FIRM panels countywide.

Preliminary map panels for the 2008 update were presented in 2006 as part of a nationwide map modernization. These new maps included previously unmapped areas and also established new floodways. Floodways are areas along rivers, creeks, canals and other natural watercourses in the Special Food Hazard Area (SFHA). Within these floodways, there are additional regulations governing construction and the placement of fill.

Lee County hosted a public open house Oct. 25, 2006 to reveal these preliminary maps to the public. Representatives of FEMA attended and discussed map modification with about 250 people.

On Jan. 31, 2007, Lee County, the city of Sanibel, the Town of Fort Myers Beach, and several private property owners appealed specific map panels. These appeals generally asked FEMA to reduce areas included in the regulatory floodways and in coastal hazard areas. These appeals changed 76 of the 155 proposed map panels.

Coastal Mapping, Assessment & Planning (Risk MAP)

In November 2014, FEMA notified Lee County that it is analyzing coastal wave action in the Gulf of Mexico as part of its Risk Mapping, Assessment & Planning (Risk MAP) program. This analysis will be used to create new elevation data for Flood Insurance Rate Maps (FIRMs). Preliminary maps will be distributed in 2018. These maps will be subject to local appeal.

Hendry, Charlotte and Sarasota counties are included in this effort.

Lee County is hiring a consultant early in this process to monitor data collection and modeling and to assist in potential appeals of the working draft and preliminary maps. This may help mitigate the need to appeal and revise the maps after they are adopted. 

The timeline for this project is general:

  • Surge and wave modeling will be done by the end of 2016;
  • Work maps will be distributed in 2017;
  • Depending on the appeal of work maps, a Community Coordination and Outreach (CCO) meeting will be held in the fourth quarter of 2018 to reveal preliminary maps.
