This project also includes the removal of 452 LF 8" sewer from permit WQ0040504 (Davis Park Townhornes Public Permit) and removal of 329 LF 8" sewer from WQ0038871 (Davis Park Apartments Permit). The sewer system has two sections, one that will be publicly owned and one that will be private. The public sewer system will be owned and operated by Durham County. The proposed development will consist of approximately 381 apartment units (285 units with the public permit), clubhouse, pool, and the associated parking areas. The total public wastewater flow generated by this project is 74,169 GPD. The receiving downstream sewer permit number for this project is WQ0038871. The sewer flows to the Triangle WWTP (permit no. NC0026051) treatment facility. The anticipated date for installation completion for the sanitary sewer system associated with the Davis Park East Pod B development is Spring 2022. The anticipated date for 1st effluent discharge (certificate of occupancy) is Fall 2022. Sincerely, THE JOHN R. MCADAMS COMPANY, INC. John C. Martin, P.E.
