The Water Resources Development Act (WRDA) of 2000, Section 601 (b)(1)(A), authorized the Comprehensive Everglades Restoration Plan (CERP) as the framework for restoration of the South Florida ecosystem. The Biscayne Bay Coastal Wetlands Phase I Project was authorized under Section 7002 (5) (5) of the Water Resources Reform Development Act (WRRDA) of 2014. The purpose of the Biscayne Bay Coastal Wetlands Project is to rehydrate wetlands and reduce point-source discharges into Biscayne Bay. The project, located in southeast Miami-Dade County, incorporates the Deering Estate, the Cutler Wetlands, the L-31E Flow-way/North Canal, and recreational features.
The decision to implement the project via two Project Implementation Reports (PIRs) was based on technical uncertainties and sponsor preference. Phase 1 of the project includes construction of seven pump stations, approximately 10 culverts reconnecting wetlands, and approximately three miles of spreader canals, and the plugging of 2,500 feet of mosquito control ditches. The Phase 1 project area is covers approximately 3,761 acres, with the northern boundary at Deering Estates and the southern boundary at the Turkey Point Power Plant.
Phase 2 extends the project into the Barnes Sound area and includes construction of 4 pump stations, mosquito ditch plugs, and culverts. Information gained through adaptive management actions in Phase 1 will support Phase 2 planning.

As part of the SFWMD Expedited Construction Plan, the SFWMD completed construction of the Deering Estate features in March 2012. This feature includes a pump station, spreader structure, and canal extension. The SFWMD completed design of the Cutler Wetland features, which include a 400 cfs pump station, a 7,000-ft concrete lined channel, a spreader canal, and associated culverts. The SFWMD portion of L-31E Flow-way includes the addition of 4 culverts that were completed in May 2010.
The Corps and the non-federal sponsor, the SFWMD, executed a Project Partnership Agreement (PPA) in August 2016. Following execution of the PPA, the Corps constructed two culverts on the L-31E Flow-way, and designed one pump station and four culverts. In 2018, the SFWMD constructed four additional culverts designed by the Corps. The Corps is currently designing the remaining L-31E Flow-way components, which consist of four pump stations and an inverted siphon. The Corps is scheduled to award construction contracts (two contracts) for the remaining L-31E features in FY20.
In January 2019, the SFWMD requested that the Corps develop a Project Management Plan and Scope of Study for the Phase 2 portion of the BBCW project as referenced in the PIR. The PMP is drafted and planning efforts are scheduled to start in late FY20.
