2: Identifying Projects
Elevation
This option involves raising residential structures so that their lowest floor is higher than projected flood depths. This measure was considered for areas with a projected flood depth of between 3 and 18 feet.
Floodproofing
This option refits structures so they can be resistant to flood damages. Residential and commercial floodproofing was considered for areas with projected flood depths of 3 feet or less.
Voluntary Acquisition
We considered this option in areas where projected flood depths make elevation or floodproofing infeasible and where residential structures would need to be elevated higher than 18 feet. Our initial estimates were that only a small percent of the total nonstructural program would need this option. We will refine this aspect of the program in close partnership with local communities. A community may wish to move as a group to preserve important cultural ties. Other communities may have different needs. Working closely with affected citizens will help us fine tune this component of the nonstructural program.
