Hurricane Rita Flood Recovery Maps (Louisiana)

Geographic Information Systems (GIS) Data

GIS is used to display and analyze spatial data that are tied to databases. The Rita Recovery Maps were developed using GIS. Several data layers from the Rita Recovery Maps are available as GIS shapefiles for download. To download the GIS data, click on one of the links below. Please refer to Mapping Methods and Data Sources page for more information on the development of these data.

Preliminary High Water Marks (HWMs)

WinZip archive containing the Shapefile of the coastal HWMs (.zip 22 KB) collected throughout southern Louisiana following Hurricane Rita. More information about the HWMs is available in the final Hurricane Rita Louisiana HWM report. (PDF 8MB)

Surge Inundation Limits

For each of the parishes listed, a WinZip archive is provided that contains the estimated Hurricane Rita storm surge inundation limits. These limits were developed using the surge-only coastal High Water Marks (HWMs) and best-available topographic data.

Please note: Because of the scarcity of HWM data in some areas, the Rita inundation limits may over- or underestimate the actual surge flooding that occurred; the GIS data provided here should therefore be viewed as estimated surge inundation limits.

Surge Elevation Contours

WinZip archive containing the Shapefile of preliminary surge elevation contours (ZIP 0.4 MB), which were derived from the surge-only coastal HWMs collected following Hurricane Rita.

Advisory Base Flood Elevations (ABFEs)

For each parish listed below, a WinZip archive is provided that contains the Shapefile of the ABFEs and ABFE zone boundaries. Flood Recovery Guidance published for each parish, which is available on the Recovery and Mitigation Resources page, provides further information on how these ABFEs were determined.

For additional information concerning these GIS files, such as the horizontal and vertical datum and other pertinent mapping details, please see the “Read Me” file included with each dataset.
