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
