FACT SHEET

COMPREHENSIVE EVERGLADES RESTORATION PLAN
Site 1 Impoundment

Construction General (C)

Congressional Districts: 18, 19, 20, 21, 22, 23, 24

 

1. DESCRIPTION

Congress authorized the Site 1 Impoundment project in the Water Resource Development Act (WRDA) of 2007. The purpose of this project is to supplement water deliveries to the Hillsboro Canal by capturing and storing excess water currently discharged to the Atlantic Intra-coastal Waterway. The 1,660 acre impoundment will store up to 13,280 acre-feet of water. These supplemental deliveries will reduce demands on Lake Okeechobee and Loxahatchee National Wildlife Refuge (LNWR). The impoundment will also provide groundwater recharge, reduce seepage from adjacent natural areas, and help prevent saltwater intrusion by releasing impounded water back to the Hillsboro Canal when conditions dictate.

The project also includes construction of a 6-acre wildlife wetland area. Benefits of Phase 1 features will reduce the amount of seepage loss from the adjacent LNWR, also known as Water Conservation Area 1. This will help maintain the stage of this conservation area, also categorized as an Outstanding Florida Water Body (OFW) which contains pristine water. Reduction in seepage from LNWR will help to increase the amount of water that remains in that natural system, especially during the dry periods.

4. STATUS

Site 1 Phase 1 construction was completed in January 2016. The Site 1 Phase 1 includes L-40 Modifications and miscellaneous features including clearing, grubbing and dewatering activities, miscellaneous demolitions, establishing onsite borrow and disposal areas, earthwork modifications to approximately 15,000-LF of the existing L-40 levee, installation of dam monitoring instrumentation, placement of turf reinforcement mat and smooth plate soil cement. The Corps transferred Phase 1 of the project to the SFWMD for Operation, Maintenance, Repair, Rehabilitation, and Replacement in December 2016. The remaining Phase 2 will include construction of additional impoundment features including recreational areas. Phase 2 of the project is on hold due to the sponsor’s current lack of interest, and may require Congressional authorization for a new total project cost due to exceedance of the 902 limit.
