Existing condition:
•Degraded low salt marsh with limited vegetation- substantial
losses since 1974
•Low in elevation
•Isolated salt marsh hummocks with viable habitat
Proposed restoration of ~35.5 acres of low salt marsh habitat:
•Install clean sandy medium to raise elevation of restored low salt
marsh to be within the top ¼ of the tidal range (i.e., from 2.36 ft
to 0.98 ft NAVD88)
•Create network of tidal channels for drainage & fish habitat
•Preserve & replant existing hummocks and plant plugs of
Spartina alterniflora
•Construct energy dissipation berm
