The objective of the Open Space Preservation Program is to expand the existing county and municipal park system in Gloucester County. Through this program the county has been able to expand all three county parks: Red Bank Battlefield in National Park, the James G. Atkinson Park in Washington Township and the Scotland Run Park in Clayton and Franklin Townships along with five additions of lands adjacent to the County golf course and greenway in Mantua Township.
The County also assists municipalities in the purchase of recreational lands through this program. Funds can be used to purchase new parks, expand existing ones or develop greenways.
In 2015, the office of Land Preservation, in cooperation with the State Green Acres Program, Mantua Township, and the South Jersey Land and Water Trust, was able to preserve the former Maple Ridge Golf Course in Mantua and Deptford Townships to create the Tall Pines State Preserve, the first state park in Gloucester County.
