6.2.1
Purpose. The general objectives of this section are to:
1.
Encourage preservation of buildings, structures, sites, settings,
and other elements of historical or architectural significance;
2.
Establish eligibility criteria for buildings, structures, sites,
settings, and other elements attaining protected status under § 6.2.2;
3.
Expand economic options for owners, by broadening the permitted uses
in various zoning districts and removing barriers presented by development
standards governing those uses;
4.
Permit flexibility of development options by modifying dimensional
requirements that might be an impediment to historic preservation;
and
5.
Provide incentives to preserve contributory elements of historic
or architectural significance, such as settings, sites, objects, monuments,
trees, or other elements.
6.2.2
Historic Eligibility Defined. Any historic building, structure, site,
setting, object, monument, tree, or any other element of historical,
architectural or cultural significance that contributes value in establishing
historical context, may qualify for eligibility under this section,
if it is included on any of the following lists or surveys:
6.2.3
Review by Historical Commission. The Historical Commission shall
review applications and advise the SPGA on whether, in the Commission's
view, the proposed renovation, repair, adaptive reuse, or relocation
preserves the historical and architectural features of the building,
structure, or elements if renovated or relocated according to the
plans.
6.2.4
Special Permit. The SPGA, after making the findings required by § 6.2.5
below, may grant a special permit to authorize the following uses
and activities in order to allow the renovation, repair, adaptive
reuse or, in limited instances, relocation of historic or architecturally
significant buildings, structures, or elements:
1.
Permit uses permitted in another district but not as of right in
the district in which the historic or architecturally significant
building, structure or element is to be located;
2.
Modify the operating or development standards contained in Table

6.9.2
Applicability.
A Special Residential Development ("SRD") is a project in which
one or more lots, tracts, or parcels of land are to be improved for
use as a coordinated site for housing and for which deviations from
the dimensional standards that apply to conventional developments
are allowed in order to achieve a diversity of household types, sizes
and affordability. Instead of determining density by dwelling type,
minimum lot area, and frontage requirements, the total Gross Floor
Area (GFA) of market-rate residential development for the tract as
a whole is limited.
No Special Residential Development shall be initiated without site plan review by the Planning Board in accordance with the provisions of this section and § 9.5 of this Bylaw.
6.9.3
Types of Special Residential Development.
1.
Site sensitive development (SSD): A special residential development
in which the number of dwellings is limited as set forth below so
that existing site features, such as natural grades, mature trees,
stone walls, and historic structures, may be retained.
2.
Compact neighborhood development (CND): A special residential development
in which the size of the dwelling units is limited as set forth below.
6.9.4
Scale of Development. The amount of development permitted in a special residential development shall be based on a proof plan showing at least two lots fully complying with the provisions of this bylaw (other than this § 6.9 and § 6.12), the Planning Board's Subdivision Regulations, and the criteria set forth below.
6.9.5
Threshold Criteria for Site Sensitive Development. An SSD shall be
designed to preserve natural features, mature native trees, habitat
areas, sloped areas, and historically or architecturally significant
buildings or places. Where possible, an SSD should be sited to preserve
mature native trees and their critical root zone.
6.9.6
Dimensional Standards. The requirements of Section 135-4.0 are modified
as follows within a special residential development:
1.
Lot area. There is no minimum lot area required; provided, however,
that the lot area for each lot shall be sufficient to safely meet
the off-street parking requirements of this bylaw and the installation
of any on-site water supply and sewage disposal facilities.
2.
Frontage. There is no minimum frontage required; provided, however,
that frontage for each lot shall be sufficient to provide for adequate
access to the building site in the judgment of the Fire Department.
Adequate access may be demonstrated by use of shared driveways, parking
lots or other means.
3.
Yard requirements. The minimum yards required by Section 135-4.0
shall apply only to the perimeter of the site but are not required
elsewhere within the site.
4.
Height requirements. The height limits in Table 2[1] shall apply, except that the height limit, as measured
by stories, shall be three stories in all districts.
[1]
Editor's Note: Table 2 is included as an attachment to this chapter.
5.
Gross floor area. Section 4.4 shall not apply. The total GFA of all dwelling units other than inclusionary dwelling units shall not exceed 115% of the sum of (1) the total area of all lots in the proof plan multiplied by 0.16 and (2) 4,550 square feet multiplied by the number of lots shown on the proof plan.
6.9.7
Dwelling Unit Count and Size.
1.
Number of dwellings. In a site sensitive development, the number
of dwellings shall not exceed the total gross floor area of the development
divided by the maximum building size determined under § 6.9.7.4,
rounded up. There is no limit on the number of dwellings in a compact
neighborhood development.
2.
Number of dwelling units. There is no upper limit on the number of
dwelling units in a dwelling. The number of dwelling units shall not
be less than the number of lots shown on the proof plan in accordance
with § 6.9.4.
3.
Dwelling unit size. The average GFA for all dwelling units in a compact
neighborhood development shall not exceed 2,250 square feet. The GFA
for any single dwelling unit in a compact neighborhood development
shall not exceed 2,800 square feet. There is no limit on the GFA of
a dwelling unit in a site sensitive development.
4.
Building size. The GFA of any building in a special residential development
other than an historic building shall not exceed 9,350 square feet
in the RO District and 7,030 square feet in the RS and RT Districts.
6.9.8
Inclusionary Housing.
1.
Inclusionary dwelling units.
a.
At least 15% of the of the sum of (1) the total area of all lots
in the proof plan multiplied by 0.16 and (2) 4,550 square feet multiplied
by the number of lots shown on the proof plan shall be incorporated
into inclusionary dwelling units, as defined by regulations promulgated
by the Planning Board pursuant to § 6.9.8.5 (the "inclusionary
GFA"). At least two-thirds of the inclusionary GFA shall be incorporated
into dwelling units eligible for inclusion on the Town's Subsidized
Housing Inventory as determined by the Massachusetts Department of
Housing and Community Development and shall remain affordable in perpetuity.
2.
Inclusionary dwelling units shall be substantially similar in size,
layout, construction materials, fixtures, amenities, and interior
and exterior finishes to comparable dwelling units in the same dwelling.
