Flood Maps

Flood Insurance Rate Map (FIRM)

The flood insurance rate map is the official map of Terrebonne Parish that displays the floodplain, more explicitly special hazard areas and risk premium zones as determined by FEMA. This is the map that is used by insurance companies for flood insurance purposes. This map was developed by FEMA to replace both the FIRM and ABFE and was adopted by Terrebonne Parish Consolidated Government on August 23, 2023 and is effective from September 7, 2023.

Flood Insurance Study

To identify a community's flood risk, FEMA conducts a Flood Insurance Study. The study includes statistical data for river flow, storm tides, hydrologic/hydraulic analyses, and rainfall and topographic surveys. FEMA uses this data to create the flood hazard maps that outline the flood risk areas in the community.

What action should be taken if a structure or property is in the Special Flood Hazard Area(SFHA)?

If you are affected by these changes, it is important to check with your insurance agent and mortgage lender to ensure that you remain compliant with the conditions of your loan.

If you feel that there is an error with the changes made to your property’s special flood hazard risk, you can request a Letter of Map Amendment & Letter of Map Revision.

Flood Map Advisory

Terrebonne Parish Consolidated Government requires that all new construction, substantial damage/improvement and elevations raise to the September 7, 2023 DFIRM plus 1’ freeboard for most and 2' freeboard for critical facilities. Projects receiving federal funding are often required to build to the DFIRM +2'.
