329Site ID:SalisburyTown:31.6Acres:YesRapid Technical Site Assessment:RestrictionFillAgricultureOtherCompleted ProjectHighPriority:This site is part of the Rings Island marsh located just north of the Merrimack River and east of Route 1. The marsh is tidally-influenced but is restricted due to an under-sized culvert beneath Ferry Road. The southwest portion of the marsh is also affected by culverts beneath two roads that provide a smaller southern hydrologic connection to the Merrimack River (see site #328). The Ferry Road culvert significantly restricts tidal flow and flushing to the upstream marsh as documented by a tide survey conducted in 2005. The wetland upstream exhibits several indicators of degraded conditions including subsidence and extensive stands of Phragmites. Restoration actions would replace the culvert under Ferry Road to restore tidal flow. Restoration potential is considered high based on the level of tidal restriction to the site and the relatively large area of upstream marsh that would benefit from increased tidal flows. See the Rapid Site Assessment for further details.Site Summary:Under DevelopmentImpact Type(s)StatusPotential Project
