Living Shorelines: Non-Structural Options
Non-structural design options are most suitable in very low energy settings where habitat restoration can be emphasized. The presence of existing tidal marshes or beaches, low banks without a lot of trees and very minor boat wake activity indicate suitable site conditions for non-structural design options.

|
Riparian Vegetation Management - Trimming tree branches overhanging a marsh to promote better growth, enhancing riparian vegetation cover, and controlling invasive species.
|
|
Beach Nourishment & Dune Restoration - Addition of sand to a beach to raise its elevation and increase its width, reshaping and stabilizing with dune plants.
|
|
Tidal Marsh Enhancement - Planting marsh grass in barren or sparsely vegetated marsh areas, adding sediment to a marsh surface to maintain its position in the tide range, repairing storm damage.
|
|
Tidal Marsh Creation - Grading a riparian area or filling a subtidal area to an intertidal elevation and planting appropriate marsh vegetation, most commonly Spartina alterniflora & Spartina patens.
|
|
Bank Grading - Changing the slope of a shoreline segment and replanting the area to reduce erosion, sometimes combined with planted marshes.
|
|
Fiber Logs - Manufactured, biodegradable logs placed in front of or behind marsh vegetation to temporarily reduce wave energy & erosion.
