C. 
Findings of the Planning Board.
(1) 
The Planning Board may issue a special permit under this Part 5 only if the Planning Board finds that the PRD is in harmony with the general purpose and intent of this Part 5 and § 195-10.7, Special permits, and that the PRD contains residential development and open space in a variety to be sufficiently advantageous to the Town and meets the purpose and intent of this Part 5, which renders it appropriate to depart from the requirements of this bylaw otherwise applicable to the zoning district in which the PRD parcel is located.
(2) 
If a special permit is granted, the Planning Board may impose as a condition thereof that installation of municipal services and construction of roadways within the PRD shall comply with the requirements of the Subdivision Rules and Regulations of the Planning Board.[3]
[3]
Editor's Note: See Ch. 255, Subdivision of Land.
(3) 
Further, the regulations of the Planning Board may require sufficient security to ensure compliance with the Subdivision Rules and Regulations, planned recreation facilities and site amenities; and may impose additional safeguards pertaining to public safety, welfare and convenience.

(4) 
Height limitation: 35 feet and 2.5 stories.
(5) 
Buffer zone. A fifty-foot border from the parcel boundary running the full length of the perimeter of the parcel. No structure shall be built within the buffer zone. The buffer zone shall remain in its natural state except:
(a) 
Trees and/or shrubs may be added to improve the buffer characteristic of the zone; and
(b) 
Roadways perpendicular or nearly perpendicular to the zone may be installed to access the site, if approved as part of this PRD special permit granted by the Planning Board. Such roadways shall be minimized within the context of sound subdivision planning practices.
E. 
Parking requirements. For all planned residential development, off-street parking shall be provided as required by Part 1, Off-Street Parking and Loading.
F. 
Usable open space. "Usable open space" shall be defined as the part or parts of land within the PRD which are reserved for permanent open space or passive recreation use. The usable open space shall be open and unobstructed to the sky. Trees, planting, arbors, flagpoles, sculptures, fountains, outdoor open-air, passive/active recreational facilities and similar objects shall not be considered "obstructions."
(1) 
Usable open space ratio.
(a) 
For subdivision PRDs, the minimum usable open space requirements shall be 35% of the total parcel area; and no more than 25% of the total amount of required usable open space shall be wetland as defined pursuant to Wetlands Protection Act, MGL c. 131, § 40, and the Town of North Andover Wetland Protection Bylaw, Chapter 190 of the Code of North Andover.
(b) 
For site-planned PRDs, the minimum usable open space requirements shall be 50% of the total parcel area; and no more than 25% of the total required usable open space shall be wetland as defined pursuant to Wetlands Protection Act, MGL c. 131, § 40, and the Town of North Andover Wetland Protection Bylaw, Chapter 190 of the Code of North Andover.
(2) 
Usable open space calculation.
(a) 
Parking areas and roadways may not be included in the calculation of open space area, but the calculation may include required setbacks, waterways, and walkways. If the Planning Board requires additional parking to facilitate use of the open space, then that added parking area may be included in the calculation of the open space.
(b) 
For the purpose of creating townhouses, condominiums, multifamily, or similar housing within a site plan special permit PRD and subdivision PRD, that area of land extending a minimum of 25 feet from the foundation of the residential structure, eave, door, steps or stairway, patio area, deck, balcony, chimney or any other structure or improvement shall be excluded from the calculation of usable open space. If a residential structure or dwelling is more than one story tall, the minimum twenty-five-foot area must be measured from the furthest point from the structure or improvement.
(c) 
The usable open space shall be contiguous. Usable open space may still be considered contiguous if it is separated by a roadway or an accessory amenity. The Planning Board may waive this requirement for all or part of the required open space where it is determined that allowing noncontiguous open space will promote the goals of this bylaw.
(d) 
Wastewater/Stormwater structures. At the discretion of the Planning Board, subsurface wastewater and stormwater management systems serving the PRD may be located within the open space, with the approval of the Planning Board. Surface systems, such as retention and detention ponds, shall not qualify towards the minimum open space required.
(e) 
Accessory structures. The Planning Board may permit up to 5% of the open space to be paved (pervious "paving" materials are encouraged) or built upon for structures accessory to the dedicated use or uses of such open space (for example, pedestrian walks and bike paths). Parking areas and areas used for vehicular access or egress shall not constitute open space.
(f) 
At the sole discretion of the Planning Board, the Planning Board may waive the conditions in this Subsection F(2), Usable open space calculation, if it finds that the project satisfies the purpose and intent of this Part 5 and improves the overall PRD design.
(3) 
Ownership and accessibility.
(a) 
For all PRDs, the usable open space shall be owned in common by and readily accessible to the owners of all the units in the PRD by any of the following groups:
[1] 
A nonprofit organization or trust whose members are all the owners and occupants of the units;
[2] 
A private organization, including but not limited to the Trustees of Reservations or Essex County Greenbelt Association, whose primary function is preservation of open space;
[3] 
The Town of North Andover; and
[4] 
Any group, as indicated by the Planning Board, which exists or is created for the purpose of preserving open space for the owners of the units located in a PRD project.
(b) 
The usable open space shall be, to greatest extent practicable, accessible to the general public (unless restricted) and not for the exclusive use of a homeowner, homeowners' association or nonprofit organization. For open space maintained strictly for active agricultural purposes, public access may be limited or completely excluded. This agricultural and access restriction shall be included as a deed restriction running with the land.
(4) 
Restrictions.
(a) 
A perpetual restriction of the type described in MGL c. 184, § 31 (including future amendments thereto and corresponding provisions to future laws), running to or enforceable by the Town, shall be recorded in respect to such land. Such restriction shall provide that the usable open space shall be retained in perpetuity for one or more of the following uses: conservation, agriculture, or recreation.
(b) 
Such restriction(s) shall be in such form and substance as the Planning Board shall prescribe and may contain such additional restrictions on development and use of the usable open space as the Planning Board may deem appropriate.
G. 
Calculation of allowable residential density.
(1) 
Except as noted in Subsection H below, the maximum number of buildable lots and/or dwelling units in a PRD will be equal to the number of buildable lots and/or dwelling units which would result from an approved conventional subdivision plan. In order to determine the residential density of a PRD, the applicant must submit to the Planning Board a plan which:
(a) 
Meets the criteria of a preliminary subdivision plan as defined in Article IV of the Rules and Regulations Governing the Subdivision of Land in effect at the time of plan submittal;[1]
[1]
Editor's Note: See Ch. 255, Subdivision of Land.
(b) 
Is fully compliant with the Zoning Bylaw in effect at the time of plan submittal; and
(c) 
Requires no zoning variances.
(2) 
The Planning Board will use this plan to determine the maximum number of buildable lots and/or dwelling units allowed in a PRD.
H. 
Density bonuses.
(1) 
Affordable housing bonus.
(a) 
For all PRDs, the total number of allowable lots and/or dwelling units may be increased up to 20% if the developer designates at least 30% of the total number of units for use in conjunction with one or more state or federal housing assistance programs. However, in the instance where the use of federal or state programs is not available to the Housing Authority, the Planning Board, after consultation with the Housing Authority, may propose alternative methods of attaining the affordable housing bonus.
(b) 
The developer shall certify, in writing, to the Planning Board that the appropriate number of dwelling units has been set aside and conveyed to the North Andover Housing Authority (or other actions are required), before the Planning Board shall grant any special permit with density bonus provisions.
(c) 
Further, the developer shall be responsible to work with the North Andover Housing Authority to initiate and conclude occupancy of said units within one year of their completion. Failure to do so shall be deemed a violation of the special permit criteria. The granting of this bonus density shall not exempt the proposed development from any other criteria required by this section or regulation contained in the Town bylaws.
(2) 
Open space bonus. For multifamily PRDs, the total number of allowable dwelling units may be increased up to 10% if the proposed PRD provides 65% usable open space consistent with the definition of usable open space as provided in this section. The granting of this bonus density shall not exempt the proposed development from any other criteria required by this section.
(3) 
Maximum density. Proposed PRDs may utilize both bonus provisions, i.e., affordable housing and open space; however, the granting of bonus densities shall not exempt the proposed development from any other criteria required by this section.
