If I have to rebuild, how do I get started? You should talk to your municipal floodplain administrator to see if your house is substantially damaged. You should also contact your municipality to see what kind of local approval you may need and what construction standards you have to build to. In addition to the DEP's elevation standards, buildings in flood zones must meet Uniform Construction Code standards that are regulated by the New Jersey Department of Community Affairs (DCA) and implemented at the local level.
