C&SF Flood Resiliency Study (I)

May 2024

Central & Southern Florida Flood Resiliency (Section 216) Study 
Investigations (I)
Congressional Districts: 9, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28


The study will recommend a coordinated and implementable solution for the Central and Southern Florida (C&SF) Project to provide continued and improved flood risk management to reduce the most immediate risk as a result of changing conditions including climate change, sea level rise, land development, and population growth at the lower east coast of Florida in Palm Beach, Broward, and Miami-Dade Counties. The study area includes the most vulnerable urbanized areas and disadvantaged communities located east of the East Coast Protective Levee, including areas upstream of the vulnerable infrastructure and the consideration of associated impacts downstream. The study is focusing on 18 coastal water control structures characterized as highly vulnerable and the primary canals conveying water to these structures.


Estimated Total Cost $19,200,000
Estimated Federal Cost $9,700,000
Allocation thru FY23 $976,000
Allocation for FY24 $475,000
President’s Budget FY25 $300,000

This study is highly important to local stakeholders due to effects of climate change on the C&SF Project infrastructure already being felt in Broward and Dade Counties. Congressional and non-federal sponsor urgency resulted in Feasibility Cost Share Agreement execution on 21 September 22. Strongly attended public NEPA Scoping meetings were held 28 November 2022 and planning charrette held 11-12 January 2023 to inform the Alternatives Milestone Meeting.  Stakeholder interest and support has remained high during the planning of the 216 Study. The AMM was held 27 March 2023 and actualized 20 July 2023. The study team determined the need for additional resources due to magnitude of system changes and number of coastal control structures impacted.

Vertical alignment on the scope and budget are pending evaluation of future without project data with the NFS and stakeholders in May 2024 and further budget coordination on design maturity guidance.

The project delivery team will prioritize locations within study area that can be advanced to the next WRDA in coordination with the NFS, the South Florida Water Management District (SFWMD), as well as stakeholders (Palm Beach County, Broward County, Miami-Dade County, the Seminole Tribe of Florida). The Jacksonville District USACE will seek vertical alignment on the scope and budget for priority structures based on future without project evaluations and level of feasibility design maturity required for the study.  The Jacksonville District USACE will seek approval of a request for additional resources that would result in additional capability in FY25 and beyond to study priority structures. The NFS is considering whether accelerated funds may expedite the level of detail to include additional structures in the recommendation.
