Ridgefield has been awarded a state Open Space and Watershed Land Acquisition grant.  $42,000 is coming to the town from the state Department of Energy and Environmental Protection.  The money will be used to add more area to Bear Mountain preserve.  The money will partially pay for about 14 acres adjacent to Hemlock Hills, allowing Ridgefield to connect a three-acre parcel of town-owned space to the 386-acre Hemlock Hills lot in the Bear Mountain area.  Nearly 26-percent of Ridgefield is considered open space and the Conservation Commission has a goal to protect 30-percent of Ridgefield's overall land as open space.
