109Site ID:EssexTown:1.2Acres:NoRapid Technical Site Assessment:RestrictionFillAgricultureOtherCompleted ProjectMediumPriority:Site consists of ~1 acre of marsh upstream (west) of the Choate Island access road. The property is owned by the Trustees of Reservations. A granite block culvert may exist beneath the road to convery tidal flow and drain the upstream wetland. TTOR staff report that this culvert may be collapsed and failing. A site visit was not conducted. The upstream marsh exhibits indicators of degradation, including stands of Phragmites and encroachment of fresh water and woody vegetation. A tidal survey may be needed to determine whether the existing culvert restricts tidal exchange with the upstream marsh. Restoration actions would replace the existing culvert with one sized to pass the full tidal range to the upstream marsh. Restoration potential is considered medium based on the relatively easy restoration via culvert replacement and ownership by TTOR. Potential is reduced due to difficult construction access to the island and the relatively small restoration opportunity.Site Summary:Under DevelopmentImpact Type(s)StatusPotential Project
