A-1 Flow Equalization Basin (FEB)The A-1 FEB project is a part ofthe overall Everglades restorationeffort and will support theoperations of STA-3/4 and STA-2/Compartment B. The A-1 FlowEqualization Basin (FEB) will bean approximately 15,000 acrebasin that will be utilized toattenuate peak storm water runoffflows being delivered to the STA-3/4 and STA-2/Compartment Bfrom the North New River Canal(NNRC) and the Miami Canal.11WesternInteriorConveyanceLevee isshorterCollection andConveyance Canalwas modifiedExistingRoads/Levees will bedegraded to adjacentgradeSeepage pumpsat G-370 will beupgraded
G-716 Three Gate Structure During high flow events from the C-51 West Basin and whenthere is capacity for storage in the L-8 FEB or when STA 1Eis receiving optimal flows, water will be diverted through S-375 & G-716 to the G-311 Structure, the addition of G-716Structure is required. G-716 Structure will be designed for acapacity of approximately 2,400 cfs.G-716
L-8 Divide Structure, G-541This Project includes the designand construction of a fullyautomated, reinforced concretewater control structure to belocated within the L-8 BorrowCanal, east of the L-8 FEB. Thestructure will be designed tofunction within the currento[perational criteria for the L-8Borrow Canal, while facilitatingflows from the STA-1 Inflow Basininto the L-8 FEB. The structure willalso be used to allow flows to bedirected south from the L-8 FEBinto the STA-1 Inflow Basin.
S-5AS Divide Structure Under the Restoration StrategiesProgram S-5A Basin a& the C-51 West Basin runoff will bedirected north through S-5AS tothe L-8 FEB. With theimplementation of this Program,the use of the S-5AS structurewill increase and therefore willrequire upgrades to ensure moreefficient operations andincreased use at higher stagesand flow rates.
