Congressional Districts: 17, 18, 20, 21, 22, 23, 25, 26, 27



The West Palm Beach Canal (C-51)/Stormwater Treatment Area (STA) 1 East project was authorized under the Flood Control Acts of 1948, 1954, 1962, and 1968, and the Water Resources Development Act (WRDA) of 1996. The project is located in Palm Beach County and runs east/west from West Palm Beach at Lake Worth to Water Conservation Area (WCA) No. 1 (Loxahatchee National Wildlife Refuge). The authorized project will provide 30-year flood protection to the urbanized eastern basin and 10-year flood protection to the western basin. All eastern basin features have been completed. During mediation of the Everglades water quality litigation, a technical plan was developed for resolution of the litigation. The technical plan included a substantially modified C-51 project. The modified plan expands the original 1,600-acre floodwater detention area into a 6,500-acre stormwater detention area. In addition to the flood damage reduction benefits provided by the original project, the modified plan provides water quality treatment, reduction of damaging freshwater discharges to Lake Worth, and increased water supply for the Everglades and other users.

Construction. Construction of works authorized by the 1962 Act were started in 1982 and completed in 1990. A series of reports and design memorandum related to the works authorized by the 1968 Act were prepared from the early 1970s through the early 1990s, which delayed construction of those works. Construction of the works authorized by the 1968 Act and the 1996 Act was concurrent, starting in 2001, and was completed in 2005. Renovation work on the culverts and trash rakes was conducted from 2011 to 2017. The completed features have been transferred to the South Florida Water Management District (SFWMD) for operation and maintenance.

Current Status. All construction/renovation activities have been completed and the project is being fiscally closed out. An audit of the work carried out by the non-Federal sponsor has been done. A letter report along with a reimbursement agreement recommending reimbursement of $921,243.00 to the NFS was completed. The agreement, along with the letter report, is under review at Corps of Engineers Headquarters. The agreement approval is currently scheduled for June 2018.
