The District of Columbia Flood Prevention Act of 2025 aims to expand eligibility for federal funding under the Coastal Zone Management Act of 1972. Its primary purpose is to include the District of Columbia among the entities that can receive financial assistance for coastal zone management and related activities. The bill achieves this by amending Section 304(4) of the Coastal Zone Management Act. This amendment specifically inserts "the District of Columbia" into the definition of "State," thereby making it eligible for the Act's programs and funding. This legislative change would allow the District to access resources for flood prevention and other coastal management initiatives.
