Living Shorelines: Structural or "Hybrid" Options
These options represent structures that are used to support planted or natural tidal marshes and sand beaches where the degree of wave energy and erosion conditions prevent the use of non-structural methods (click on photo for enlargement. See Structures Glossary for term definitions (.pdf)
|
Marsh Toe Revetment - Low profile revetment placed along the eroding edge of an existing tidal marsh, may include tidal openings.
|
|
Marsh Sill - Low profile revetment backfilled with sand to create an intertidal marsh, may be a long continuous structure or in sections with tidal gaps.
|
|
Marsh with Groins - Fringe marsh creation on graded sand fill stabilized by small stone containment groins placed perpendicular to the shoreline.
|
|
Living Breakwater - Offshore breakwater with vegetation planted behind the structure.
|
|
Offshore Breakwater System -
Series of rock revetments strategically placed offshore to refract waves producing a scalloped but stable shoreline.
|
|
Oyster Reef -
Bagged or uncontained oyster shell placed along a marsh edge or in shallow water close to shore. The most suitable sites have very low wave energy because oyster shell piles are not very resistant to wave action.
