Detailed Project Report And Environmental Assessment Wilson Branch Chesterfield County South Carolina Revision

The recommended plan of improvement for Wilson Branch consists of demolishing six houses which lie below the 10-year flood plain on Wilson Branch. These six adjacent houses lie in a reach from 500 to 1500 feet from the mouth of Wilson Branch. All disturbed areas would be planted with grass, shrubs and trees to prevent erosion and to restore a natural appearance. Project lands would be obtained and controlled by the local project sponsor for maintenance purposes. Local project sponsors must also enforce flood plain ordinances to assure that any future development of the residual flood plain would be compatible with the flood hazard. Estimated first cost for implementation of the recommended plan is $314,590 plus an additional $120,000 in related cost for the relocation of current occupants of affected flood plain structures. Average annual project benefits resulting from the implementation of the recommended plan of improvement are estimated to be $27,440 in flood damage reduction benefits to existing development.
