When, in accordance with the provisions of Chapter 240, Zoning, Articles XXV and XXXXII, an applicant wishes to submit a subdivision plan as a planned residential development, the following regulations will govern, in addition to those elsewhere in these subdivision regulations. The endorsement "Approved for Planned Residential Development" shall be given only if the subdivision complies with the subdivision regulations and with all applicable requirements of Chapter 240, Zoning. Subdivision plans for planned residential development shall only be approved upon a finding by the Planning Board that the proposed site can be appropriately developed using a cluster site design and that important topographical features and/or natural open areas may be preserved and/or enhanced.
A. 
A definitive subdivision plan for a planned residential development shall be submitted in accordance with §§ 305-6 and Article IV of these regulations and shall be accompanied by an application for a special permit for planned residential development and other information as required in the special permit application, in accordance with Chapter 240, Zoning, Articles XXV and XXXXII. Multifamily dwelling projects may use § 240-126 of Chapter 240, Zoning, to establish density and open space without the subdivision of a lot. A site plan review shall accompany the submission of a multifamily plan, in accordance with Articles XXV and XXXIX of Chapter 240, Zoning.
B. 
A copy of the special permit application shall be submitted to the Town Clerk to validate submission.
Whenever practical, a joint public hearing shall be held by the Board on the application for subdivision and the application for a special permit for planned residential development. Notice of the public hearing to consider the two applications shall be advertised and sent to all parties of interest at the expense of the applicant, who shall supply names and addresses as appearing on the most recent tax list, for owners of land abutting the subdivision and abutters to abutters (including those directly opposite on any public or private street or way) within 300 feet of subdivision property lines.
Approval of a subdivision plan for planned residential development shall be subject to performance guaranty (§ 305-17), special permit for planned residential development (Articles XXV and XXXXII of Chapter 240, Zoning) and an agreement approved by the Planning Board, ensuring the maintenance of the open space as specifically stated in § 240-131 of Chapter 240, Zoning.
