What Elements are Used to Determine the Floodplain?
The main responsibility for establishing floodplain management rests with local governments that have the power to direct how certain land will be used and developed within their boundaries. In many jurisdictions, a Floodplain Administrator issues permits and makes sure that the programs and policies are enforced. In addition, federal and state governments and river authorities can provide financial and technical help in order to carry out floodplain management programs.
Your local regulatory authority must first determine what kind of resources it has available to protect its citizens, including finances, manpower, equipment and other considerations. It then establishes a regulatory floodplain based on the size of the flood and total area it can reasonably expect to manage.
