Common areas and facilities. The provision of certain facilities serving the entire development, such as parking lots, interior pedestrianways, driveways, lighting facilities, landscaped planting areas, buffers and open space and recreation facilities, etc., are hereby encouraged and may be located either on individual lots or in common areas. In cases where they are provided in common areas, provisions satisfactory to the Board of Commissioners must be made for their perpetual maintenance and care. Use of these facilities may be restricted to the residents of the development, where practical, and they may be maintained by the developer, a homeowners' association or a similar instrument. Any common area shall be first offered to the Township; however, the Township need not accept dedication of the open space but shall maintain first option to purchase, which may be executed at any time with 12 months' notice.
