C&SF Flood Resiliency Study (I)

May 2023

Central & Southern Florida Flood Resiliency 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 of Miami Dade, Broward and southern Palm Beach Counties, located as the eastern side of the East Coast Protective Levee, including areas upstream of the vulnerable infrastructure and the consideration of associated impacts downstream. A total of 18 coastal structures have been characterized as highly vulnerable based on the results of south studies, as follows: S20, S20-F, S123, G93, S21, S22, S25, S25B, S26, S27, S28, S29, G58, G54, G57, S33, S36 and S37A.


Estimated Total Cost $3,000,000
Estimated Federal Cost $1,500,000
Allocation thru FY22 $500,00
Allocation for FY23 $475,000
President’s Budget FY24 $425,000

The Feasibility Cost Share Agreement was executed 21 September 2022.  Public National Environmental Policy Act (NEPA) Scoping meetings were held 28 November 2022, followed by the initial planning charrette held 11-12 January 2023. At the Alternative Milestone Meeting (AMM) in March 2023, the Project Development Team (PDT) presented time and cost exception information to the Vertical Team (VT). The PDT is working with the VT on technical details of scope and implementation, aiming for VT alignment by the end of May 2023.

The C&SF Study was authorized in WRDA 2022 and will consider multiple project purposes including Flood Risk Management, Water Supply, and Aquatic Ecosystem Restoration which could recommend additional studies and authorize projects for immediate implementation. The Flood Resiliency Study will thus focus on immediate needs and short implementation timeline with the Comprehensive Study filling in gaps for additional short and long-term strategic plans.
