In 2006, the park was expanded after a 575-acre (2.33 km2) tract in the center of the forest came on the market, called Sterling Forge. Although Sterling Forest LLC developers had planned to construct 107 luxury homes and an 18-hole golf course on the tract, local residents and concerned environmentalists rallied and were able to procure the tract for the state park.[11][12] The final $13.5 million sale price was negotiated by The Trust for Public Land, and paid in part out of the state's Environmental Protection Fund.[3]
