Terms of protection
In 1991 in an effort to ensure the land would always be available to those that had come to enjoy its offerings Dorothy incorporated Stone Quarry Hill Art Park as a non-profit art park. A conservation easement protects the 104 acres of land from future development and maintains the aesthetics of Stone Quarry Hill's history, first as a quarry and then in the late 1800s as a working farm.
