There is a slim possibility that we won't be given the right to grant variances again. We won't know until the review is over, though. Without variances all building in the flood plain must follow the zoning laws. Structures must be either elevated above the flood plain or built to be flood proof. Raising a building above the flood plain could mean anywhere from six to 10 feet above the existing grade depending on the location, according to Rinehart.
Flood proofing a structure is more complicated and more costly.
Kentucky Fried Chicken, on the corner of Fourth and Pike Streets is the only building in the flood plain that was constructed with flood proofing. Flood proofed structures must be anchored to the ground, which is difficult in Marietta because of the type of soil, Rinehart said. The KFC had to use pilings driven into the ground. After anchoring the building the walls then have to be designed to withstand the pressure of flood waters. Doors and windows also have to be sealed over.
