DESCRIPTION OF PROJECT:  The Scope of Work for this project includes the construction of the following major structures.

1. One single barrel, ungated, 4.5’ diameter, High Density Polyethylene (HDPE) culvert which conveys water from an area north of Mitigation Area ‘A’ to the headwater of the C-512 canal.
2. One pump station with a 1,050cfs total capacity for seepage and intake flows to the impoundment.
3. One single barrel, 5’x6’ box culvert with remotely operated slide gates which serves as an embankment dam discharge.
4. One double barrel 8’x8’ box culvert with slide gates which serves as the embankment dam’s main discharge structure.
5. One emergency discharge overflow spillway with a crest width of 150 feet. 
6. One single barrel 8’x8’ box culvert with weir and sluice gate, which provides optimal seepage stage and discharge excess seepage from the C-511 canal to the C-11 Canal in the event of a power failure at the seepage pump bank.
7. Three broad crested weir structures; sheet pile with a concrete cap.
8. One single barrel 10’x10’ ungated box culvert, which provides conveyance of seepage from the C-511 canal to the C-11 canal. This culvert also provides access over the top along SW 45th Street to the S-503 Pump Station.
9. One double barrel 6’x6’ungated box culvert, which provides access across the C-511 canal from SW 26th Street to the top of the D-511 embankment.
10. One cast in place concrete pipe culvert with 4’ diameter internal HDPE form and slide gate, which provides a water passage from the impoundment to Mitigation Area ‘A’.
11. One double barrel 6’ diameter HDPE culvert with stoplog risers, which discharges Mitigation Area ‘A’ to the C-512 canal.
12. One single 4’ diameter barrel HDPE gated culvert, which provides conveyance of water from Mitigation Area B to the C-512 canal.
13. One triple barrel 6’ diameter HDPE culvert with flap gate, which provides conveyance for seepage to the C-511 canal.
14. One single 4’ diameter barrel HDPE culvert with 4’ diameter internal HDPE form and risers, which provides conveyance for seepage to the C-511 Canal.
15. One ungated 48” HDPE culvert, which provides drainage conveyance from environmentally sensitive lands to the C-511 canal.
16. One single barrel 30” HDPE gated culvert, which controls wet and dry season flows from an existing mitigation area to the C-511 canal.

Location of Project

The Comprehensive Everglades Restoration Plan Broward County Water Preserve Areas, C-11 Impoundment Plan is located in Broward County.  

Specific Project Challenges

The C-11 Impoundment encapsulates approximately 917 acres of wetlands; some quality wetlands and some of lesser quality. Approximately 215 acres of quality wetlands have been identified for avoidance during construction (i.e. no borrow, avoidance of staging and access, and mechanical clearing of stands of woody vegetation of greater than 4-inches only).

The work will require significant surface and groundwater management for the duration of construction to ensure proper foundation preparation and construction occurs per project specifications.  USACE will obtain the appropriate Comprehensive Everglades Restoration Plan Regulation Act (CERPRA) permit from the Florida Department of Environmental Protection (FDEP), however the construction contractor will be responsible for obtaining additional permits from the FDEP and the SFWMD for water use authorization and stormwater discharge during construction.

Work will require the excavation and processing of several million cubic yards of material to be used as embankment fill.  Embankment dam internal drainage features will have very specific criteria and will require importing material from off-site.  The full interior and crest of the embankment dam will be covered with soil cement.  Aggregate for soil cement will be obtained from off-site sources. 

The proposed structures will require construction of cofferdams and significant dewatering to maintain a dry working surface on the cofferdams interior for construction of these mass concrete structures.  Cofferdams and dewatering system design for the structures will be the responsibility of the construction contractor.
