CERP Project:
Big Cypress - L-28 Interceptor Modifications

Modification of levees and canals, water control structures, pumps, and stormwater treatment areas (with a total storage capacity of 7,600 acre-feet) will re-establish sheetflow from the West Feeder Canal across the Big Cypress Reservation and into the Big Cypress National Preserve, maintain flood protection on Seminole Tribal lands, and ensure that inflows to the North and West Feeder Canals meet applicable water quality standards. Upstream flows entering the West and North Feeder Canals will be routed through two stormwater treatment areas to be located at the upstream ends of the canals. Sheetflow will be re-established south of the West Feeder Canal consistent with the Seminole Tribe's Conceptual Water Conservation System master plan.

The initial design is for a 1,900 acre (water level fluctuating up to 4 feet above grade) stormwater treatment areas located near the Miccosukee and Seminole Indian Reservations in Collier and Hendry Counties. Conceptual sizes of the stormwater treatment areas were based on interim phosphorus concentration targets in the conceptual plan for the Everglades Construction Project. The final size, depth and configuration of this facility, including the stormwater treatment areas, will be determined through more detailed planning and design.
