WHAT IS A LIVING SHORELINE AND WHY IS IT IMPORTANT?
A “Living Shoreline” is a green infrastructure technique
that uses a suite of bank stabilization and habitat restoration methods to
reinforce the shoreline, minimize coastal erosion, and maintain coastal
processes while protecting, restoring, enhancing, and creating natural habitat
for fish and aquatic plants and wildlife. Living shoreline projects
typically utilize a variety of structural and organic materials, such as
wetland plants, submerged aquatic vegetation, oyster reefs, coir fiber logs,
sand fill, and stone.
WHAT IS THE CITY OF MIAMI BEACH DOING?
The City of Miami Beach is considering living shoreline
techniques, as well as hybrid stabilization shoreline systems in areas where
seawalls need to be rehabilitated to address shoreline stabilization, tackling
erosion protection while preserving and enhancing environmental conditions.
Developments such as the Brittany Bay Park seawall rehabilitation project aim
at protecting mangrove stands and introduce a natural shoreline within the
existing structural seawall. Given its’
deteriorating seawall cap, as well as the natural recruitment of mangroves
along the seawall, the rehabilitation will be the first hybrid design where the
City of Miami Beach incorporates a structural sea wall with a living shore line
WHAT ARE THE KEY BENEFITS OF LIVING SHORELINES?
The City of Miami Beach recognizes the significant
environmental benefits of living shorelines. Benefits of living shorelines:
Stabilization of the shoreline; Reduction of wave energy and coastal erosion;
Absorption of storm surge and flood waters; Improved water quality via
filtration of upland run-off; Maintenance of natural shoreline dynamics and
sand movement; Protection of riparian and intertidal resources; Restoration of
critical spawning, feeding, and nesting areas for wildlife; and, Creation of
habitat for aquatic and terrestrial species.
WHERE ARE OTHER EXAMPLES OF LIVING SHORELINES?
Miami Beach has successfully implemented the living
shoreline approach. Besides the Muss Park, Brittany Bay Park and other upcoming concept
projects (Indian Creek Dr), residents can enjoy living shorelines around city
parks such as the Maurice Gibb Memorial Park (18th St & Purdy Avenue) and
the Pinetree Park (4400 Pinetree Drive) living shorelines.
