Article 6 Permitted Exceptions: Future Development Conditions
6.02 (a.) The Buyer will maintain in perpetuity no less than fifty percent (50%) of the total Property area as open space, which may include playing fields, wooded areas, paths and trails and other active and/or passive recreational areas and facilities. For the purposes hereof, the term “open space” may also include conservation land, forested land, recreation land, agriculture land, corridor parks and amenities such as small parks, green buffers along roadways, undeveloped land with particular conservation or recreation interest, or any open area that is owned by an agency or organization dedicated to conservation. Without limiting the foregoing, that portion of the Property that lies between Route 135 and the Cochituate Aqueduct (as each of the same currently exists) will remain in a wooded and natural condition, provided that this requirement will not be deemed to restrict periodic clearing of invasive vegetation and other care and maintenance measures that are consistent with sound forestry management practices;
(Note: The six acres located between Route 135 and the aqueduct will count towards the 50% open space requirement. Note also that open space can mean playing fields, and facilities to support the fields, such as bathrooms and parking lots.)
