Coastal Flood Maps (reference here as flood maps) are used to determine the minimum elevation needed for construction to reduce the chances of flooding, as well as construction methods required in certain zones. The Federal Emergency Management Agency (FEMA) released new PRELIMINARY flood maps for Monroe County. Monroe County wants to ensure all residents and owners are aware of the potential for changes for their property so that they can be informed and make proactive decisions.
90-Day Appeal Ends June 17, 2021
All private appeals must be received by Monroe County by 5 p.m. on Thursday, June 3, 2021.

Flood Map Comparison Application
Monroe County created an application that shows property owners the current Effective FEMA Flood Maps, the FEMA Preliminary Flood Maps, and the County’s Appeal Flood Maps developed by Woods Hole Group for Monroe County’s appeal of the Preliminary FIRMs
- Flood Map Comparison Application (application best viewed in Google Chrome or Firefox browsers)
To use this application, simply enter in the RE# (real estate number format 00000000-000000), the AK# (alternate key number format 0000000), or the Owner's Name (last name, first name format) within the red search box (top left) and the application will zoom to the property, showing a three-pane side-by-side comparison of the maps. For questions, email FloodMaps@MonroeCounty-FL.gov or call 305-453-8759. To find the RE# or AK# for your property, search the Monroe County Property Appraiser website with a property address or an owner's name.
PLEASE NOTE: This application does not search for properties by Address, and the data in this application is ONLY for Unincorporated Monroe County and does not reflect any of the incorporated municipalities in Monroe County.
DISCLAIMER: The Preliminary Flood Maps and the County’s Appeal Flood Maps are NOT FINAL or ADOPTED. These maps may indicate a future change to required elevation for future construction; however, until such time as FEMA issues a Letter of Final Determination and Monroe County adopts the FIRMs (final flood zone maps), all information in the Preliminary Flood Maps and County Appeal Flood Maps are subject to change. Property owners/applicants are being informed about the upcoming release of the new flood maps and that the permitting requirements may change based on the final flood maps. Please note, the Preliminary Flood Maps and the County’s Appeal Flood Maps are preliminary and subject to an appeal. The final outcome will not be known until the appeal(s) are resolved and an Applicant’s/Owner’s use of this preliminary data is at their own discretion.
