Rather than wait for a flood to occur, you can act now to protect your property from flood damage. Various alternatives are available to help minimize flooding. If the floor level of your property or structure is lower than the Base Flood Elevation (BFE) located on the city's Flood insurance Rate map (FIRM), consider ways to prevent flooding from occurring such as retrofitting your building. “Retrofitting” means altering your building to eliminate or reduce flood damage.

Retrofitting measures include:

  1. Elevating the building so that flood waters do not enter or reach any damageable portion of it,
  2. Constructing barriers out of fill or concrete between the building and flood waters,
  3. “Dry flooding” to make the building walls and floor watertight so water does not enter.
  4. “Wet floodproofing” to modify the structure and relocate the contents so that when flood waters enter the building there is little or no damage, and
  5. Preventing basement flooding from server backup or sump pump failure.

There are several good references on retrofitting in the city of Grand Prairie's public library. Many of these will inform you about retrofitting techniques and help you decide which is best for you.
