Minimum development site area: five acres. The five acres may be comprised of individual lots of less than five acres which, when combined, will be considered to be one development site. Once the lots are combined to constitute a development site, there shall be no further subdivision of the site which would result in a development site of less than five acres.

Minimum lot frontage for the development site on a public way: 50 feet.

Minimum lot frontage within the development site: none, provided that the interior roads, which must provide adequate access for all buildings on the development site, shall not become public ways and are to be considered private access roads. Fifty feet of frontage is required for each lot if the roads are intended to be considered public ways.

Minimum lot area for individual lots within the development site: none.

Minimum setbacks of buildings from development site interior property lines and private access roads: none.

A minimum of 40% of the development site shall remain undeveloped Open Land.

Multiple buildings and uses shall be permitted on a single lot.

Adequate pedestrian access shall be provided to the Open Land. The Open Land may remain as part of the overall development site and need not be a separate parcel, but there shall be deed restrictions stating that there shall be no further development of the Open Land. The Open Land may consist of a separate parcel and may be conveyed to a nonprofit organization, the purpose of which is the preservation of open space. If the Open Land is conveyed to another entity, it shall continue to be part of the development site for the purpose of calculating dimensional requirements.

The Open Land shall consist primarily of undisturbed land which may be used for outdoor active or passive recreational purposes and shall be planned as large, contiguous units wherever possible. If privately owned, the Open Land may be used solely by occupants of the development site or may be available for use by the general public. The decision as to whether to permit the general public to use the Open Land shall be that of the property owner or as provided for in the deed restriction. The Open Land may be comprised of more than one parcel, provided that the size, shape and location of such parcels are suitable for the above purposes.

Setback areas from exterior development site property lines of 100 feet or more may be counted as part of the Open Land as long as such setback area is part of the deed restricted area referred to in this section.

Curb cuts on streets shall be minimized, and to the greatest extent possible, buildings shall be located away from public ways and surrounding residential uses.

Outdoor lighting fixtures shall be shielded and directed to prevent illumination from falling onto adjacent lots and streets.

Interior roadways shall remain private and shall not become public ways. The design of interior roadways shall conform to the Design Standards of the Rules and Regulations Relating to the Subdivision of Land, with the exception that the Planning Board may waive such Standards if desirable. Utilities shall be underground.
