The C-11 Basin is a region of west central Broward County, Florida, the western portion of which is drained into the Everglades through the C-11 Canal. The C-11 West Basin is an area of 72 square miles (45,701 acres), which includes five municipalities (the Cities of Cooper City, Pembroke Pines, Sunrise, and Weston and the Towns of Davie and Southwest Ranches). The C-11 West Basin has experienced a population explosion since 1985.
The C-11 Basin is part of the original Everglades, and would naturally have standing water many months per year. The original inhabitants of the C-11 managed to live on the few tree islands, and navigated by dugout canoe. Conservation areas in the background of Interstate-595 show approximately what the area looked like before massive drainage projects, road construction, dredge-and-fill, and construction activities were initiated. Now the residents of the area are working together to reduce the impacts of their livelihood on the surrounding environment.
Numerous governments, agencies, and associations are directly responsible for the C-11 Basin. Just the management and permitting of water use is controlled and/or managed by the South Florida Water Management District and three Special Districts, the Central Broward Water Control District, the South Broward Drainage District, and the Indian Trace Development District governed by the City Commission of the City of Weston working with other municipalities and two Divisions of Broward County government, as well as homeowners' associations (HOAs) who are often responsible for some aspects of canal and lake maintenance. Other state and Federal agencies, such as the US Army Corps of Engineers (US-ACE) are responsible for broader issues of canal management and Everglades Restoration. Other environmental and human issues in the C-11 are handled by still more governments and agencies.
