The main purpose of this legislation is to amend the Coastal Zone Management Act of 1972 to enable the District of Columbia to receive federal funding. This funding is intended to support efforts related to coastal management and flood prevention. Key provisions of the legislation include a specific amendment to the definition of eligible entities under the Coastal Zone Management Act. The amendment adds the District of Columbia to the list of areas that can qualify for federal funding. This change allows the District to access resources that were previously unavailable to it under this law.
