An easement on West Locke Road, Concord was donated to the City of Concord in 1992. An executory or backup interest in the easement was accepted by Five Rivers. In effect, this allows Five Rivers to enforce the easement terms if the grantee, the City of Concord, fails to do so.

The easement protects an area between some commercial development and a large wetland complex. It protects the edge of this wetland, owned by the City of Concord, which has been shown to provide valuable wildlife habitat. After this donation, significant additional acreage was placed under easement in this general area near the Merrimack River. Multiple conserved parcels now combine to protect a variety of wetland and floodplain habitats, as well as expansive river frontage and productive agricultural lands.
