WRDA 2000 Initial Projects:
C-111 North Spreader Canal
Description – Modify the ongoing C-111 Project by increasing the capacity of C-111N and extend the canal approximately two miles under U.S. Highway 1 and Card Sound Road into the Model Lands. Backfill lower end of the C-111 canal and remove S-197
Purpose - Improve water distribution and enhance the connectivity and sheetflow in the Model Lands and Southern Glades area, and reduce damaging wet season flows in C-111 to Card Sound and Florida Bay
Benefits – Improve water deliveries and enhances the connectivity and sheetflow in the Model Lands and Southern Glades areas, improves the quality of water discharged into the Model Lands, Southern Glades, and Florida Bay
Land Status - Ongoing land acquisition programs by State and local agencies; 2,451 acquired by SFWMD, 3,780 acquired by Miami-Dade County, 495 acres acquired by the State, for a total of 6,231. 6,184 acres remaining to be acquired. Total estimated acreage requirement - 12,415
C&SF Restudy Component - "WW"
General Description: This project has been sited in south Miami-Dade County in the Southern Glades and Model Lands areas. The project includes modifications to the ongoing C-111 Project to improve water deliveries and enhance the connectivity and sheetflow in the Model Lands and Southern Glades area, and reduce damaging wet season flows in C-111 to Card Sound and Florida Bay. These modifications include expanding the proposed
Criticality: This project is included in the initial authorization for several reasons: 1) early authorization will allow for inclusion into the ongoing detailed design and construction of the C-111 project, and 2) inclusion of a stormwater treatment area to provide water quality treatment of agricultural runoff prior to distributing water through the C-111N spreader canal. This project will improve deliveries and enhance the connectivity and sheetflow in the Model Lands and Southern Glades areas, reduce wet season flows in C-111, and decrease potential flood risk in the lower south Miami-Dade County area.
Engineering Design: This project includes construction, modification or removal of levees, canals, pumps, water control structures, culverts and a stormwater treatment area. This project enhances the C-111 Project design for the C-111N Spreader Canal with: the construction of a 3,200 acre stormwater treatment area; the enlarging of pump station S-332E from 50 cfs to 500 cfs; increasing the capacity of C-111N for the higher capacity of flow and the extension of the canal approximately two miles under U.S. Highway 1 and Card Sound Road into the Model Lands; and culverts under U.S. Highway 1 and Card Sound Road. The initial design of this project pumps water from the C-111 and the C-111E Canals through two 250 cfs pump stations into a stormwater treatment area prior to discharging through S-332E to the Southern Glades and the Model Lands through the C-111N Canal. This project also fills in the southern reach of the C-111 Canal below C-111N to S-197; removal of structures S-18C and S-197; completely backfilling C-110; and removal of adjacent levees and roads. The final size, depth, location and configuration of this project will be determined through more detailed planning and design.
Benefits: This project improves deliveries and enhances the connectivity and sheetflow in the Model Lands and Southern Glades areas, reduces wet season flows in C-111, and decreases potential flood risk in the lower south Miami-Dade County area while improving the quality of water discharged into the Model Lands and Southern Glades areas.
Related Projects: This project enhances the ongoing C-111 Project design for the C-111 N Spreader Canal with the addition of a stormwater treatment area, enlarged pump station S332E, and extension of the canal under U.S. Highway 1 and Card Sound Road into the Model Lands.
Schedule: This project is currently scheduled for construction initiation in July 2005 with completion in July 2007. Of the 12,415 acres needed for this project, the SFWMD and Miami-Dade County and the State have acquired 6,231 acres to date. This schedule is based on a very optimistic real estate acquisition plan.
