Storm Climatology & SelectionįEMA use of a single Coastal Reference Point (CRP) in Miami-Dade County to establish a set of synthetic storms for modeling is not representative of the Keys (see picture below). Errors or inconsistencies with the first five study components could result in regional impacts to the FEMA Flood Insurance Rate Maps (FIRMs), while issues with the last three study components could result in more localized impacts to the FIRMs. A summary of the study components of concern is provided below. The review identified eight RiskMap study components that are of concern because of (a) the use of non-standard approaches in certain study areas, (b) inconsistencies in methodology with other FEMA Coastal RiskMap studies, (c) discrepancies between the RiskMap documentation and the analyses, or (d) possible errors in the analysis. Woods Hole Group completed a review of FEMA’s December 2019 RiskMap study for Monroe County.

Summary of FEMA RiskMap Review for Monroe County The technical consultant will also be reviewing the maps and modeling conducted by FEMA and is prepared to appeal any of the maps that do not appear to be correct. The County has hired a consultant to analyze how flood risks are changing in Unincorporated Monroe County based on the provided studies using updated information and the best available science and technology. 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. Please note, the Preliminary Flood Maps and the County’s Appeal Flood Maps are preliminary and subject to an appeal. 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. 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. 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.ĭISCLAIMER: The Preliminary Flood Maps and the County’s Appeal Flood Maps are NOT FINAL or ADOPTED. 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. 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. Flood Map Comparison Application (application best viewed in Google Chrome or Firefox browsers).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 PowerPoint Presentation (PDF).Coastal Flood Maps, otherwise known as Flood Insurance Rate Maps (FIRMs) 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.
