New 2019 Preliminary Coastal Flood Maps
This preliminary data has been presented by FEMA as the best information available at this time and includes new or revised Flood Insurance Rate Maps (FIRMs), Flood Insurance Study (FIS) reports and FIRM Databases. This release provides community officials, the public, and other stakeholders with their first view of the current flood hazards, which include changes that may have occurred in the flood hazards and risks throughout the County since the last flood hazard map was published in 2012.
Flood hazards and associated risks can change over time and water flow and drainage patterns can change dramatically because of surface erosion, land use, and natural forces. Thus, preliminary flood hazard maps help inform public officials, floodplain managers, industry stakeholders, and the public about how the community’s flood hazards and risks have changed.
In Fiscal Year 2013, the Federal Emergency Management Agency (FEMA) initiated a coastal flood risk study for the Southwest Florida Study Area that affects Charlotte, Collier, Desoto, Hendry, Lee, and Sarasota Counties. The results of that study will be incorporated into updated digital Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) reports for these counties.
What Areas of Collier County have been included in this study?
In terms of the flood maps, the County is divided into a total of 156 FIRM panels. The panels in blue color (see image) are the panels included in the study.

Preliminary National Flood Hazard Layer
The Flood Map Changes Viewer (FMCV) is the best way to view the Preliminary National Flood Hazard Layer and Preliminary Changes Since Last FIRM (CSLF) data in a map. The Preliminary CSLF view provides a visual of proposed changes to flood extents or proposed changes to zone designations for a location. The FMCV features the Preliminary Map Comparison Tool through which you may print a report featuring a side by side comparison of effective data and preliminary data a selected location.
Preliminary Map Comparison Tool (PMCT): The PMCT allows customers to see Effective and Preliminary maps overlaid on one another. With this tool, users can view the latest hazard information overlaid with the existing information and save or print a report detailing the changes between these two data sets side-by-side for a single point of reference. A tutorial is available to provide additional information on how to use the Preliminary Map Comparison Tool.
Instructions for Using the FMCV:
- The Preliminary National Flood Hazard Layer is a geospatial database that contains current preliminary flood hazard data. The information can be used to better understand proposed flood hazards in your community.
- Read the welcome message and press “OK” to continue to the FMCV
- Type into the address search bar on the top right corner of the page either the exact address, the zip code, or the city and state of the location for which you want to view flood map data
- Select the magnifying glass symbol to the right of the address search bar or press enter on the keyboard to execute the search and navigate to the location
- The symbol directly to the left of the address search bar with three pieces of paper is the Layer List symbol, which opens a list of the operational layers that are viewable in the FMCV. Users may select or de-select boxes next to the layers to have the data appear or disappear from the FMCV.
- The symbol directly to the left of the Layer List symbol is the Legend symbol with a triangle, square, and circle bulleted list. Pressing the Legend Symbol will open a legend defining the various symbols and colors displayed in the FMCV.
- The plus and minus symbols on the bottom left corner of the FMCV allow users to zoom in or out from the map location.
- The public may access their community’s preliminary data by visiting the Preliminary Data Search Tool or through the MSC through the Search All Products or Product Availability Table.
- The preliminary data webpages listed above undergo periodic maintenance. If you are unable to access your community’s preliminary data through these channels, please visit this alternate site
- To explore the current digital preliminary flood hazard data in a map, the best tool to use is the Flood Map Changes Viewer. From the Flood Map Changes Viewer, you may view, download, and print flood maps for your location
FEMA MAP REVIEW PROCESS OPEN HOUSES
Recently, FEMA conducted multiple Flood Risk Open Houses in Collier County, Marco Island and the City of Naples to give residents and property owners the opportunity to review how the recent preliminary FIRM affects their homes and businesses.
Attendees had the chance to ask questions about flood insurance and other mechanisms for reducing the flood risk to their homes, businesses, and families. They were able to confer with local and state officials about the appeal and compliance periods and the map adoption process.
GMD Leadership, Geographical Information Systems and CFM Staff has established an action plan in which staff will be conducting a feasibility analysis in order to provide recommendations to FEMA regarding any known mapping product deficiencies. Staff will also incorporate the details of the newly released preliminary maps into its annual outreach program. Property owners and residents may direct inquiries to staff through the Flood Information Hotline listed at the bottom of the page.
Appeal and Comment Period
- Communities in Collier County will have a 90-day appeal period for all changes to Special Flood Hazard Areas.
- SFHA changes will be published in the Federal Register.
- SFHA changes will be published in the local newspaper twice within a 10-day period.
- The second newspaper publication will begin the 90-day appeal period.
- According to FEMA, the Base Flood Elevations (BFE) shown on the preliminary flood maps are determined by experienced mapping experts using the latest engineering methods and computer models. The results are based on professional expertise of the mapping engineers, the amount of data collected and the precision of measurements made.
- For that reason, an appeal must be based on data and documentation showing that the proposed flood elevations shown on the preliminary maps and/or in a Flood Insurance Study (FIS) report are scientifically or technical incorrect. Parties that are interested in appealing the changes, need to demonstrate that better methodologies and or data exists and provide alternative analyses that incorporate those methodologies and or data. The results must show an overall change in the Base Flood Elevations.
- Communities in Collier County will also have a comment period.
- Comments do not involve BFEs.
- Comments include, but are not limited to, the following:
- Channels Names and Locations
- Road Names and Locations
- Corporate Limit Changes
