In August 1995, Hollow Oak accepted the donation of sixty acres of open space on the north side of the Beaver Valley Expressway. Located in both Moon and Hopewell Townships in Allegheny and Beaver Counties, this property was named the Boggs Run Conservation Area because one of its borders lies along that stream valley near the headwaters of Boggs Run. A beaver dam helps to maintain this wetlands habitat with its rich plant and animal life. Although this conservation area has been untouched by construction, the property is crossed both by electric power line towers and by a gas line. The land formerly was used for pastures and crops.
