This site directs you to information you can use to understand how predicted flood levels may impact you, how you can reduce flood damage and how you can recover and rebuild once the floodwaters recede.
Elevation provides the best protection for flood damage, short of relocating the house to an area that is less prone to flooding. Raising a structure does not remove it from the special flood hazard area (SFHA); therefore, it does not exempt the owner or the mortgage company from flood insurance mandates.

If you have decided to restore your storm-damaged home, you’ve already determined that your neighbors are probably coming back, that public utilities will be restored (or you will provide your own), that you will have police, fire and medical services and that there will be jobs and schools. Other things to consider include new building regulations, cost estimates, debris removal, opportunities to upgrade systems and add space.

This site was created for people who are rebuilding or restoring their homes following a hurricane. Though designed as a tool for participants in the Road Home program, it can be a valuable resource for anyone planning a building, restoration, renovation or remodeling project in Louisiana. The information was developed jointly by the LSU AgCenter, Tulane City Center and UNO-CHART.
Registry Off Line: The original Rebuilding and Restoration site included a registry of building industry professionals, to help homeowners who are rebuilding or remodeling find qualified, licensed building contractors who work in their area. Homeowners could send information about their rebuilding and restoration projects to contractors who did the kind of work needed. Countractors could respond by sending their direct contact information to the homeowner. The Registry has been suspended while we evaluate its performance and the need for it. Inquiries may be sent to firstname.lastname@example.org.
