Alternate text does not appear on pages with the maps as the maps convey spatial data and have various layers of data which can be selected or de-selected individually. For information about a specific location, the 'Identify Feature Properties' function may be used to click on the map and generate a information window with details about underlying map layers

While the floodplain data that is shown on this map is the same, this map is not an official FEMA Flood Insurance Rate Map (FIRM). This Interactive Mapping Tool is not intended for insurance rating purposes and is for information only. Locating property on the Aerial/Roads Hybrid view is more accurate than geocoding the address. Please contact your local floodplain administrator for more information or to view an official copy of the Flood Insurance Rate Map (FIRM).

Points Use this tool to view information about the points represented by your pins. This information can be viewed for each pin, also, by clicking on the head of the pin. Point info for flood maps is read only from digital maps. Additional information for each point is pulled from the US Geological Survey (LIDAR ground elevation) and the LSU AgCenter (Basic Wind Speed for the residential building code in Louisiana), and DOTD (Community Contacts)

Flood Maps

The most widely distributed flood map product in the United States is the Flood Insurance Rate Map (FIRM) of the National Flood Insurance Program (NFIP). FIRMS have been furnished predominantly as paper maps, which are still being used in many communities. FEMA now provides FIRMS in digital form; these work well in map-layering systems and enable information from the map to be read electronically. Read more about how FIRMs are made and used.

Effective FIRM is the FIRM that is used to rate NFIP flood insurance policies. Older FIRMs were delivered as paper products; newer FIRMs are delivered as true digital products. For older FIRMs we display a scanned image of the paper map that has been processed somewhat to improve the alignment of features shown on the map (such as road intersections) with their position as determined by high resolution imagery. Use the Legend â€œFIRM (Scanned paper or gray-scale).â€ For newer FIRMs we display the data as it is provided to us by FEMA. Use the Legend â€œEffective FIRM (Digital).

Preliminary FIRM is a FIRM presented to a community as part of the production or revision process. FEMA provides the Preliminary FIRM and the underlying Flood Insurance Study (FIS) to communities for review and comment, and considers those comments when producing the final product. The Preliminary FIRM becomes a Future FIRM when FEMA issues a Letter of Final Determination (LFD). The Preliminary and Future FIRMs are never used for rating flood insurance, but may be used by the community for regulating development. Preliminary FIRMs present the most up-to-date flood risk information until they are replaced by their Future FIRM. Use the legend â€œProposed FIRM (Digital)â€

Future FIRM is the FIRM that was delivered to the community as a Preliminary FIRM and, after review and expiration of comment and appeals periods, has been adopted by the community and/or determined by FEMA to become the next Effective FIRM. The Future FIRM will become the Effective FIRM on the Study Effective Date (SED), which is six months after the date of the Letter of Final Determination (LFD). LFD and SED are shown in the 'Events' tool. The Future FIRM is not used for insurance until the Study Effective Date; it may be used by the community for regulating development. Future FIRMs present the most up-to-date flood risk information. Use the Legend â€œProposed FIRM (Digital)â€

Historical FIRM is the FIRM that was retired when the Future FIRM became the new Effective FIRM. Historical FIRMs that were issued originally as paper products are displayed as scans of the paper map. Historical FIRMs that were issued as digital products are shown in gray-scale, but remain fully digital. Use the Legend â€œFIRM â€“ (Scanned paper or gray-scale). On this site we show only the most recent Historical FIRM. Earlier historical FIRMs for the community may be available at the FEMA Map Service Center(http://msc.FEMA.gov).

Advisory Base Flood Elevation (ABFE) is a temporary Base Flood Elevation issued by FEMA after a disaster for use during recovery, while the FIRM is being revised to reflect risks discovered in the disaster event. ABFEs are never used for rating insurance. They may be used by the community to regulate some or all development. ABFEs were issued across coastal Louisiana following hurricanes Katrina and Rita and communities were required by the state to adopt ABFEs as a regulatory standard for rebuilding or forfeit hazard mitigation funding. ABFEs are retired by the next revised FIRM.
