No more than 50 of the 1120 new Dwelling Units so constructed may be single-family dwellings, and the remainder shall be multi-family dwellings, including attached dwellings, garden apartments, units in mixed-use buildings and Senior Housing Developments.
Neither the dwellings located at 80, 82, 83 nor 90 East Main Street or 26 Clinton Street, nor the Group Home located at 44 Wilson Street, all of which were in existence as of the effective date of this Article, shall be deemed to be a Dwelling Unit for the purposes of this Intensity of Use limitation.

All Affordable Housing shall be integrated with the rest of the Development Project in which it is located, and shall be comparable in design, exterior appearance, construction, and quality of exterior materials with other units in such Development Project. The mean number of bedrooms in Affordable Housing Dwelling Units shall be no greater than the mean number of bedrooms in the market-rate Dwelling Units in the Development Project in which they are located.
C. 
In addition to the Affordable Housing requirements provided in Subsection A of this Section, to the extent that the Senior Housing Developments create a total number of Dwelling Units within the OSMUD District in excess of 940, those Senior Housing Developments shall require the provision of, in the aggregate, one Dwelling Unit of Affordable Housing for every 10 Dwelling Units in Senior Housing Developments, but not to exceed twenty (18) Dwelling Units of Affordable Housing in the aggregate.

D. 
The Planning Board may, by Special Permit, approve an amount of parking less than applicable minimum parking requirements of § 210-124(B) (1), as modified by this Section, if it finds that the lesser amount of parking will not cause excessive congestion or endanger public safety, and that the lesser amount of parking will provide positive environmental or other benefits.

Prior to the commencement of a Construction Activity, the North Parcel, consisting of not less than 68 acres, and the South Parcel, consisting of not less than 35 acres, both as shown on the Official Zoning Map, shall be made subject to a Restricted Land Covenant designating such land as open space Restricted Land to be left in substantially its natural state, restored or landscaped, in perpetuity. Thereafter, land designated as Restricted Land shall be subject to a Restricted Land Covenant in accordance with the provisions of Subsection E below.
D. 
Except with respect to the North Parcel and the South Parcel, which may not be released from their Restricted Land Covenants, the Restricted Land Covenants applicable to any Restricted Land may provide that such Restricted Land may be released from a Restricted Land Covenant by an instrument executed by the owner, the Planning Board and the Select Board, and recorded, provided that not less than an equivalent area of land is made subject to a Restricted Land Covenant and substituted therefor, subject to the approval of the Planning Board.

The North Parcel and the South Parcel may be designated to meet the Restricted Land requirement for Development Projects within the OSMUD District.
In the event that less than 500 acres have been made subject to a Restricted Land Covenant at the expiration of fifteen (15) years from the filing of a Notice pursuant to the provisions of § 210-172, the owner or owners of such additional land as is required to achieve the 500-acre total shall subject such land to Restricted Land Covenants. In the event that such owner or owners have not made such additional land as is required to achieve the 500-acre total subject to Restricted Land Covenants within 60 days of the expiration of such period, the Planning Board may designate one or more parcels as are required to achieve such 500-acre total, and such parcels shall forthwith be made subject to a Restricted Land Covenant by the owner or owners thereof. The Planning Board shall have the authority to extend such deadline to a later date upon a finding that the holder or holders of the Master Plan Special Permit are continuing to pursue development of the OSMUD District and have not yet achieved substantial completion notwithstanding good faith efforts. The foregoing obligation shall be binding and enforceable pursuant to the provisions of Article XXIV only upon the owner of the parcels required to be restricted at the expiration of such period, as it may be extended, and shall not affect the compliance with this Chapter of any lot in a Development Project which has received Site Plan Approval prior to the expiration of such period, as it may be extended.
F. 
Restricted Land may be (i) owned by a Landowners’ Association, (ii) owned by a non-profit entity, a principal purpose of which is land conservation or the provision of recreational facilities, (iii) conveyed to the Town, or (iv) owned by, made subject to easement rights benefiting, or leased to third parties. In all such cases the uses permitted by such deeds, easements or leases of required Restricted Land shall be consistent with the provisions of this § 210-170, the Master Plan Special Permit and the applicable Restricted Land Covenant. A Landowners’ Association or other party responsible for Restricted Land may adopt reasonable rules and regulations to govern the use of the Restricted Land under its control and to prevent encroachment thereon.
G. 
Restricted Land Covenants shall specify the permitted uses of specific parcels of Restricted Land; the responsible party to be charged with maintenance and stewardship of the Restricted Land in perpetuity; and a required program for such maintenance and stewardship. Applications for Site Plan Review of Development Projects shall include an agreement authorizing the Town to perform maintenance or stewardship of areas designated as Restricted Land in connection with the approval of such Development Project in the event of any failure to comply with the required program for maintenance and stewardship of the Restricted Land, after thirty (30) days notice to the Landowners’ Association or other responsible party and failure of the Landowners’ Association or such party to cure such failure; provided, however, that, if the Town elects to perform any maintenance or stewardship work, the responsible party therefor shall pay the cost thereof, which cost shall constitute a lien, subordinate to any mortgage or other statutory lien, upon the properties in connection with which the Restricted Land was originally designated, until the cost has been paid.
H. 
Nothing in this Section shall be interpreted to preclude the owner of Restricted Land from imposing additional restrictions on the Restricted Land or a Conservation Restriction or Agricultural Preservation Restriction under M.G.L. c. 184 § 31-33 which are not inconsistent with the applicable Restricted Land Covenant.
A. 
The Planning Board shall be the Special Permit Granting Authority for any Special Permit authorized by this Article. The Planning Board may adopt and file with the Town Clerk Regulations governing Submission Requirements and Procedures for any such Special Permit.
B. 
In all matters in which it has jurisdiction to issue a use Special Permit pursuant to § 210-165, the Planning Board may issue such Special Permits only upon a finding that the proposed use is in harmony with the general purpose and intent of this Chapter. Any such Special Permit shall be subject to such conditions and safeguards as the Planning Board may prescribe.
