Floodproofing reduces the damage a building will suffer when floods happen. The most effective on-site floodproofing is to have the habitable (finished) space above the anticipated flood level. For residential structures, elevating the floor is the only method that makes the building compliant with flood damage prevention ordinances. For non-residential buildings, compliance can be achieved using a technique called dry floodproofing, in which the building is sealed to prevent entry of floodwater. There are a number of permanent modifications to a building or grounds that can be effective in reducing flood damage, but do not bring the structure into compliance. These provide no insurance premium reduction and generally are not eligible for federal mitigation funding. In this presentation we will review the important features of these flood protection method and discuss some of the pros and cons associated with each.
