In an effort to preserve the land for continued agricultural use, Placer Legacy, the California Department of Conservation, and Placer Land Trust established an agricultural conservation easement on a 40-acre Newcastle farm property. The easement, finalized in February 2010, prevents any use or development of the property that would significantly damage or impair the property or its agricultural values. The Natural Trading Company is certified organic by the California Certified Organic Farmers. Public access is not permitted.
