32nd Street Hot Spot, Florida
The Miami Beach 32nd Street Hot Spots stabilization project represents an innovative approach to hot spot management. Coastal Systems International, Inc. designed a system of three artificial headlands to stabilize the shoreline in the vicinity of 32nd Street. Numerical modeling using Danish Hydraulic Institute’s (DHI) Mike 21 software was performed to assess the potential for downdrift impacts and optimize the headland configuration.
In addition to artificial headland construction, this project included sand recycling. Sand recovered from accreting areas of Miami Beach was used to prefill the structures and nourish the beach at 32nd Street. This approach resulted in lower construction costs and an efficient use of sand resources.
