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.
