Reduce undesirable discharges to east and west coast estuaries
Deliver “new” sources of clean water to the Central Everglades and ENP
Restore habitat in the central Everglades

CENTRAL EVERGLADES PLANNING PROJECT (CEPP)
PROPOSES TO:
Move water south from Lake Okeechobee through Everglades Agricultural Area (EAA)
Improve benefits to the Caloosahatchee and St Lucie estuaries
Store and treat flows with proposed flowage equalization basin (FEB) in the EAA
Send treated water south through Water Conservation Area 3A (WCA 3) and a flowway portion of 3B, and into Everglades National Park and Florida Bay

SPATIAL PERSPECTIVE North of the Redline
Combination of features to increase water deliveries downstream and improve estuarine benefits
South of the Redline Features and their locations to best restore
sheetflow in northern Water Conservation Area 3A
Greenline/Blueline Features to best restore sheetflow through southern
WCA-3A and 3B
Configuration of conveyance features to best restore flows to Everglades National Park
Yellowline Features to best compliment rest of project and
manage seepage to the eastern urban area without impacting the water supply

STORAGE AND TREATMENT
DISTRIBUTION/CONVEYANCE
Increase S-333 capacity to 2,500 cfs Two 500 cfs gated structures in L-67A, 0.5 mile spoil removal west of
L-67A canal north and south of structures Construct ~8.5 mile levee in WCA 3B, connecting L-67A to L-29 Remove ~8 miles of L-67C levee in Blue Shanty flowway (no canal back fill) One 500 cfs gated structure north of Blue Shanty levee and 6,000-ft gap
in L-67C levee Remove ~4.3 miles of L-29 levee in Blue Shanty flowway, divide structure
east of Blue Shanty levee at terminus of western bridge Tamiami Trail western 2.6 mile bridge and L-29 canal max stage at
9.7 ft (FUTURE WORK BY OTHERS) Remove entire 5.5 miles L-67 Extension levee, backfill L-67 Extension canal Remove ~6 mile Old Tamiami Trail road (from L-67 Ext to Tram Rd)
Increase S-356 pump station to ~1,000 cfs Partial depth seepage barrier south of Tamiami Trail (along L-31N) G-211 operational refinements; use coastal canals to convey seepage
FEB Pump
Note: System wide operational changes and adaptive management considerations will be included in project
