Structures shall be erected and premises otherwise developed
only as here permitted. Premises shall be developed only for uses
as permitted in this Bylaw.
[Amended 3-7-1970 ATM by Art. 45; 3-4-1972 ATM by Art. 45; 3-27-1976 ATM by Art. 27]
Except as otherwise specifically provided in this Bylaw, a dwelling
or other main building shall be erected or used only on a lot meeting
the standards for a basic lot or for one of the flexible optional
alternative lot types hereunder.
A.
The basic lot is the reference standard for the Bylaw. The access
frontage may be less than that for the basic lot only if all lot requirements
or one of the optional alternatives hereunder are met. Type 2 (hammerhead),
Type 4 (backland), Type 5 (mini-subdivision), and OSC-PRD lots are
permitted only by special permit authorized by the Planning Board.
[Amended 3-29-1980 ATM by Art. 29; 3-28-1981 ATM by Art. 23; 3-31-1990 ATM by Art. 18; 4-2-2005 ATM by Art. 32; 4-2-2005 ATM by Art. 37]
(1)
The foregoing requirement for a special permit shall not apply to
a hammerhead or backland lot shown on a plan endorsed by the Planning
Board before March 28, 1981. Each building lot shall contain:

of required lot area which contains at least a portion of the lot
width circle required for the particular type of lot.
(b)
An access from the street to said buildable area.
(c)
At least 3/8ths of an acre upland, exclusive of land within
50 feet of an inland wetland.
|
The foregoing provision (c) shall not apply to lots identified or defined of record prior to April 2, 2005, without regard to considerations of adjoining land held in common ownership as provided in Section 6 of Chapter 40A of the General Laws and in the Harvard Protective Bylaw in § 125-2.
|
(2)
Except for Type 3 lots, and portions of Type 1 lots located on a
permanent turnaround in an approved subdivision, a lot whose permitted
frontage is less than that of a basic lot shall have frontage (with)
radius of curvature of not less than 175 feet.
C.

2 or Type 3 or Type 4 lot.
[Amended 3-29-1980 ATM by Art. 29]
D.
Type 2 lots (hammerhead lots).
[Amended 3-26-1977 ATM by Art. 28]
(1)
Lots shall have:
(a)
Land area of at least 4.50 acres, which may be reduced to 2.50
acres with the approval of the Harvard Planning Board only if the
difference is distributed among adjoining lots as permanent excess
over their ordinary requirements, and on the condition that the hammerhead
lot as reduced meets all the applicable requirements of the Bylaw,
and further that the lots receiving the additional acreage shall meet
all applicable requirements of the Bylaw prior to the addition of
the new acreage.
[Amended 3-26-1983 ATM by Art. 25; 3-28-1987 ATM by Art. 60; 2-5-1990 STM by Art. 4]

Upon receipt of a written statement from the Planning Board
or its agent indicating that:
[1]
A satisfactory driveway and turnaround for the purposes of construction as defined in § 125-31D and meeting the foregoing standard and other applicable provisions of this Bylaw have actually been provided; and
[2]
Where the lot contains area in a W District, a water hole with
suitable access has been provided or is already available, within
1,000 access feet of each building on the lot.[1]

Editor's Note: Former Subsection F(4), regarding shared driveways,
as amended, which immediately followed this subsection, was repealed
3-31-2007 ATM by Art. 23.
G.
Type 5 lots (lots in a mini-subdivision). It is the intent to provide lots for the optional limited development of backland by means of permanently private access in accordance with the conditions of a special permit authorizing a mini-subdivision (see § 125-34), and whatever other permits may be required.
[Added 3-28-1981 ATM by Art. 25]
(1)
All of the following conditions shall be met:
(b)
Every building shall be located entirely within the compact contiguous area of buildable land defined in this § 125-29, Lot size standards, and entirely within the lot width circle required for this type of lot.
(c)
Shared driveways are not permitted to lie on, or serve, the
lot.
(d)
Maximum grade of driveways shall be no more than 10%.
(e)
Driveways on the lot shall have a length no greater than 300
feet, except by special permit authorized by the Planning Board, and
then only if the Board finds building locations and lot layout conform
to the distance criteria in the following statement of intent. It
is the intent that all parts of every building site within the buildable
area lie well within, and at most no more than, 1,000 feet of combined
lot-plus-access driveway length of fire hose from the side line of
a regular street, or from an approved fire pond water takeout, without
unduly constraining driveway location within the lot or along its
frontage.
(2)
This (Type 5 lots) subsection and § 125-34, Mini-subdivisions, are intended to be considered together. Type 5 lots shall not be created or used except in accordance with the terms of the special permit(s) authorizing the mini-subdivision and such further conditions as may be imposed by the Planning Board acting in accordance with the provisions of this Bylaw and the Subdivision Control Law.
[Amended 3-27-1982 ATM by Art. 36; 11-16-1987 STM by Art. 12]

|
Except as otherwise specifically provided in this Bylaw, structures and other improvements shall conform to this section and to Article VI (see definition of "section").
[Amended 4-30-1994 ATM by Art. 40] |
A.
Number of structures on a lot. Structures
on a lot shall be such that each dwelling or other main building,
with its associated accessory structures, can be provided simultaneously
with its own lot, with the lot and structures thereon conforming to
the Bylaw.
B.
Floor area ratio. Total building floor area (all levels,
all buildings) shall not exceed 10% of the land area of the lot, or
8,000 square feet (whichever is larger). For an institutional use
by the Town of Harvard on land located within 2,500 feet of the Town
center intersection of Routes 110 and 111, such limit shall be 20%
of the land area of the lot.
[Amended 3-28-1987 ATM by Art. 72; 11-30-1999 STM by Art. 12]
C.
Height. The height of a building, other than a church,
above average grade shall be less than three stories and less than
35 feet. For purposes of this provision, silos, and chimneys, ventilators,
antennas (except for wireless communications towers and antennas),
spires, and similar unoccupied projections above the roof are not
included in building height.
[Amended 6-19-1997 STM by Art. 6]
D.
Visibility. Any sign, fence or landscape plantings,
within 20 feet of the street side line and between heights of 2 1/2
and 7 feet, shall be such as not substantially to impair visibility
between any driveway and oncoming street traffic.
E.
Setbacks. Setbacks as follows, except that waterfront structures need not be set back from the waterfront (see also Article II, Existing Lots, Structures and Uses):
(1)
Any main building shall be located within the compact, contiguous area of buildable land defined in § 125-29, Lot size standards, and for hammerhead and backland lots, within a circle contained in the lot and having a diameter at least the minimum required lot width.
(2)
Structures other than fences shall be set back from lot boundaries
by at least the height of the structure.
(3)
Except for the Commercial District, structures other than fences, signs, and poles shall be set back from the lot boundaries by at least 20% of required lot width or of (maximum) lot width, whichever is lesser. In the Commercial District such structures shall be set back at least 20 feet from side and rear property lines. If property use is subject to § 125-39, Site standards, such setback shall be at least 60 feet from abutting property in an AR or MR District. For an institutional use by the Town of Harvard, such extended (sixty-foot) setback requirement shall not apply if the existing use of the abutting property would itself be subject to § 125-39, Site standards.
[Amended 4-21-1992 STM by Art. 4; 11-30-1999 STM by Art. 12; 4-5-2016 ATM by Art. 53]
(4)
Structures other than fences, signs, and poles shall be set back from the center line of any roadway, provision for future roadway, or easement or right-of-way for vehicular access connecting three or more lots to the street, by at least 75 feet. Such setback shall also apply to swimming pools. However, except for swimming pools, such setbacks do not apply for roads serving only lots in an OSC-PRD. Excluding the Commercial District, along arterial streets or if property use is subject to § 125-39, Site standards, such setbacks shall be at least 125 feet. In the Commercial District such structures shall be set back from the front lot line a minimum of 20 feet. However, for an institutional use by the Town of Harvard on land with its access on Route 110 or 111 within 2,500 feet of the Town center intersection of Routes 110 and 111, such extended (one-hundred-twenty-five-foot) setback shall not apply. For purposes of the Bylaw, arterial streets are Ayer Road from the Southerly crossing of Bowers Brook, approximately Station 140, to the Ayer Town line, Massachusetts Avenue from Fairbanks Street to the Boxborough Town line, and Still River Road from Willow Road to the Bolton Town line, except for a distance on Still River Road 1,000 feet north and south of the intersection of Still River Road and Still River Depot Road.

For purposes of public safety, any driveway constructed after March 30, 1996, of more than 300 feet in center-line length and providing access from the public way to a main building shall be constructed in accordance with the standards for driveways set forth in the bylaw § 125-39B. No such driveway shall be constructed without site plan approval by the Planning Board at a regularly scheduled public meeting. Construction of all such driveways shall be subject to inspection by the Planning Board's driveway inspector, fees for said inspections to be paid by the applicant as specified in the Planning Board's regulations.
A.
No driveway which serves two or more building lots of any type, or
which serves a hammerhead or a backland lot, or which serves a use
for which a special permit or site plan approval is required, may
lie on a corridor of land or land area having a width of less than
35 feet and lot frontage of less than 50 feet. This subsection shall
apply only to driveways constructed, and to lawfully existing driveways
changed after that date to connect with or serve one or more additional
lots.
B.
Shared (common) driveways. To reduce the impact of impervious surfaces and the number of driveway cuts, it is the intent to permit adjoining lots to share a driveway which, except for branches serving individual lots, lies on or near their mutual boundaries subject to a recorded maintenance and snow plowing agreement to ensure that the driveway will be maintained and remain useful for both ordinary and emergency access under all weather conditions, and to ensure that a driveway will not be used as a substitute for a street or as a substitute for mandatory access frontage (see § 125-29). After March 26, 1988, a driveway may be constructed or extended to serve more than one lot only in accordance with a special permit authorized by the Planning Board (see § 125-46, Special permits), subject to all applicable provisions of this bylaw. For a shared driveway serving only single- and two-family residence uses, the driveway site standards in § 125-39B shall apply (see § 125-38, Site plans, and § 125-39, Site standards).
(1)
At most four lots, of which no more than three shall be hammerhead or backland lots, may be connected to or otherwise share the same driveway. This provision (increasing the number of lots from three to four) will apply only to common drives built or extended by special permit after March 25, 1995. The driveway shall lie entirely within the lots being served. This subsection shall apply only to shared driveways constructed after February 9, 1979, and to lawfully existing driveways changed after that date to connect with or serve one or more additional lots. (Added driveway requirements for hammerhead and backland lots are contained in § 125-29D, Type 2 lots, and § 125-29F, Type 4 lots.)
(2)
Each branch of a shared driveway shall include a turnaround for vehicles
including moving vans, ambulance, fire, and police.
(3)
(Reserved)
(5)
Grades on shared driveways constructed or extended after March 26,
1988, shall not exceed 8%.
(6)
A shared driveway which is constructed, or extended to serve additional
lots or uses, after March 26, 1988, shall begin at the street on which
the lots served have their access frontage. A driveway shall not be
used to provide the lot access frontage required by this bylaw or
by the Subdivision Control Law. Where the access to structures or
uses provided by the driveway is substantially different than that
which would be provided through required lot frontages, the special
permit shall not be issued unless the Planning Board finds that the
proposed shared driveway and its location are in the public interest.
C.
Driveway site plan approval. For lots or uses for which
a special permit is required by this bylaw as amended, the installation
or extension of a driveway to serve a new main building or a new use
shall be in accordance with a driveway construction site plan approved
by the Planning Board, with advice from the Director of the Department
of Public Works with respect to driveway connection to the street.
Such driveway construction site plan approval shall expire if the
work thereunder is not begun and diligently pursued to completion
within two years after issuance.
D.
For any shared driveway, or any driveway requiring a special permit
or site plan approval by the Planning Board, a building permit shall
be issued only upon receipt of a written statement from the Planning
Board or its agent, indicating that the driveway has been cut-in at
the location shown on the plan for the purposes of construction to
the lot.
(1)
For the purpose of actual construction, driveway centerline radii may be sharper than 80 feet, provided that the entire lot is in the AR District and also provided that the entire driveway is laid out and constructed in accordance with the provisions of § 125-39, Site standards, including § 125-39B. However, the driveway center-line radius of curvature may not be less than 40 feet, except in circular turnarounds for cars only. If so constructed or extended, driveway curvature shall be considered "satisfactory" for the purpose of the written statement required prior to issuance of a building permit on a Type 2 or Type 4 lot by the provisions of § 125-29F(3)(b).
(2)
The Planning Board may consider the construction of a driveway or
its extension "satisfactory" for the purpose of said written statement
if the location of the driveway is consistent with the special permit
or site plan approval; it is suitable for access by construction and
safety vehicles to within 100 feet of the building site, provided
that there is a (perhaps temporary) turnaround for vehicles including
trucks near the building site; all drainage and erosion control measures
required for the driveway are in place; and all related measures required
by any special permit for construction have been met.
(3)
A temporary occupancy permit or use of the premises served by such
a driveway shall be permitted only upon receipt of a written statement
from the Planning Board or its agent, indicating that all drainage,
utilities, and erosion control measures are in place; that the driveway
is complete up to and including base gravel; and that all related
measures required by any special permit or site plan approval have
been met.
(4)
A final occupancy permit or use of the premises for the final lot
served by such a driveway is permitted only upon receipt of a written
statement from the Planning Board or its agent indicating that a driveway
and turnaround have been completed in accordance with the special
permit or approved site plan, and that an "as built" has been filed
with and approved by the Board or its agent.
E.
Crossing of W District and inland wetlands. Driveways which are constructed after April 8, 1989, and any existing driveway extended after that date to serve an additional use or main building, shall not alter 5,000 square feet or more of combined W District and/or inland wetlands (all non-overlapping crossings summed). Installation of driveways crossing W and WFH Districts may be subject also to special permit; see §§ 125-25 and 125-26.
F.
Long driveways. For purposes of public safety, after January 1, 1999, any driveway having or resulting in a center-line length greater than 1,400 feet from the public or private way to any main building served by that driveway may be constructed, or extended to serve another main building more than 1,400 feet from the way, only in accordance with a special permit authorized by the Planning Board (see § 125-46, Special permits), subject to all applicable provisions of this bylaw. No special permit shall be granted under this section unless the Planning Board finds that all dwellings which are served by the driveway have available a water source within 1,400 accessible hose feet which is adequate for fire protection.
(1)
In determining whether a water source is adequate for fire protection
the Planning Board may request the written advice of the Fire Department
and will consider the capacity of the water source, the availability
and adequacy of access to the water source for fire protection, and
provisions for maintenance of the water source.
[Amended 3-30-1974 ATM by Art. 40; 3-29-1980 ATM by Art. 25; 3-26-1983 ATM by Art. 26; 3-31-1984 ATM by Art. 27]
|
[See also §§ 125-1, 125-11A(1), 125-25C, 125-26B and 125-38A(3)]. The intent is to protect the public health and the environment in view of the severity of soil limitations in Harvard for sewage or wastewater disposal, and the high vulnerability of Harvard's wetlands, water absorption areas, water-bearing bedrock fissures, groundwater supply, and individual wells to pollution and contamination. Except for parts of Fort Devens, there is no system of common public sanitary sewers in Harvard. The inhabitants depend for the most part on individual wells for their drinking water, and will continue to do so for the foreseeable future, since no large sand and gravel aquifers have been located in the Town which could serve as a municipal groundwater supply.
[Amended 3-26-1988 ATM by Art. 37; 4-30-1994 ATM by Art. 34] |
A.
Integrity. When land is divided, an existing main building
and its existing well for drinking water and its existing sewage system,
including pipes, shall remain on one undivided lot.
B.
Flooding and wetlands. Sewage disposal systems shall
be set back from W District boundaries, and from the boundaries of
inland wetlands, by at least 100 feet; this setback shall not apply
to revision of any preexisting sewage disposal system. Storage areas
or tanks for chemicals or petroleum products, or other potential sources
of substantial contamination, shall be set back from W District boundaries,
and from the boundaries of inland wetlands, by at least 100 feet.
C.
Setbacks.
(1)
Intent.
(a)
In the light of the generally severe soil conditions and the
dependency of most inhabitants upon their own wells for drinking water,
mentioned above, the intent is to avoid not only the increased danger
of pollution or contamination created by the concentration of sewage
from several sources into a single small area and thereby avoid vulnerability
to larger-scale pollution or contamination of the groundwater and
wells in the event of septic system malfunction or failure than in
the case of smaller well-separated individual systems, but more particularly,
to avoid contamination by the potential leaking of raw sewage from
joints in the pipes which collect the sewage, and from cracks potentially
resulting from the installation of sewer lines over ridges of ledge
located close to the surface which are highly prevalent in Harvard,
to spread out sewage disposal installations from one another, to place
responsibility for maintenance of each septic system clearly upon
the individual owner of the lot it serves, to assure ready identifiability
and accessibility of all parts of the system for maintenance by the
responsible individual, and to separate the use of land for sewage
disposal from the use of adjoining land, streets, and other ways for
surface and subsurface drainage.
[Amended 3-26-1988 ATM by Art. 37]
(b)
In addition, the intent is to avoid the danger of contamination
caused by potentially leaking sewage lines, installed under, across,
or within the side lines of streets or other ways by private individuals
or private entities, thereby subjecting such privately installed lines
to potential damage by pressure from the weight of traffic passing
over them, especially heavily loaded vehicles, or damage during the
installation, repair, or replacement of buried cables or other utility
lines.
[Amended 3-26-1988 ATM by Art. 37]
(2)
Any means for the storage or disposal of sewage or other potential
sources of contamination, even if wholly or partly below grade, including
absorption areas and provisions for the expansion thereof:
(a)
Shall be entirely within the lot being served unless such means
is owned, operated, monitored, maintained, repaired, and subject to
replacement by the Town of Harvard or any other entity all of whose
expenditures are subject to authorization by the Harvard Town Meeting.
[Amended 3-25-2000 ATM by Art. 34]
(b)
Shall be set back from lot boundaries and drainage easements
by at least the same distance as required for structures from lot
boundaries for the particular lot. However, this setback does not
apply to solid wall pipes with leak-tight fittings (including cleanouts)
which are part of a domestic sewage system. Setback increases for
use or intensity of use which may be specified in the Bylaw shall
not apply to such means.
[Amended 3-25-2000 ATM by Art. 34]
(3)
Backfill and return to grade which are adjacent to an absorption
area shall be entirely within the lot.
(4)
Exceptions, under the provisions of this subsection:
(a)
The absorption area of a leaching facility for sewage disposal
need be set back from a street side line by a minimum of only 25 feet.
(b)
If the entire leaching facility is below both natural and finish
grade, the absorption area of the leaching facility for sewage disposal
need be set back from drainage easements and side and rear lot lines
by a minimum of only 25 feet.
(5)
For the purpose of the subsection (only), "street" includes any street,
as defined in this bylaw; any provision for any future street; and
any easement or right-of-way for vehicular access (including driveway)
connecting two or more lots to the street. The term "absorption area"
is the plan projection of the bottom of the excavation for the leaching
facility as described in Title 5 of the State Environmental Code (1995
or as revised).
[Amended 4-5-2016 ATM
by Art. 54]
(6)
The provisions of this subsection do not apply to the upgrade (as
defined by Title 5) of sewage systems for an existing structure or
dwelling, or would restrict the execution of a mandatory order of
the Board of Health to abate or forestall a threat or nuisance to
health.
[Amended 4-5-2016 ATM
by Art. 54]
D.
Communal disposal. In view of the severity of soil limitations
in Harvard for sewage or wastewater disposal, and the high vulnerability
of Harvard's wetlands, water absorption areas, water-bearing bedrock
fissures, limited groundwater supply, and individual wells to pollution
and contamination, it is important, in order to protect the drinking
water, the public health, and the environment, that any communal or
central sewage or wastewater disposal or treatment plants or systems
which may be built in Harvard be constructed, owned, operated, monitored,
maintained, repaired, and replaced by the Town rather than by private
individuals, associations, or other private entities, since such plants
or systems typically handle substantial amounts of sewage, require
frequent monitoring, have a useful life far shorter than that of the
buildings they serve, and pose a substantially greater threat to pollution
or contamination of wetlands, water absorption areas, groundwater,
and wells in the event of malfunction or failure than do the smaller
individual systems serving individual homes.
[Added 3-26-1988 ATM by Art. 38]
(1)
For these reasons, and to carry out the intent and purposes stated elsewhere in this subsection and § 125-1, Purpose, the use of privately constructed or privately owned, operated, or maintained communal sewage or wastewater disposal or treatment systems, facilities, or plants serving two or more main buildings for commercial or residential use is prohibited pursuant to Section 2A of Chapter 808 of the Acts of 1975, Article 89 of the Amendments to the Massachusetts Constitution amending Article II of the Amendments (known as the Home Rule Amendment), the Zoning Act, and other provisions of law. A building permit shall not be issued for a building to be served by such a privately constructed, or privately owned, operated, or maintained communal system or plant. The prohibitions in the preceding two sentences of this subsection shall not apply, however, to the use by two or more (main or accessory) buildings on the same lot, with Board of Health approval, of a subsurface sewage disposal system which existed on March 26, 1988, nor of such a system if the plan therefor was approved by the Board of Health on or before that date.
[Amended 4-30-1994 ATM by Arts. 34 and 35]
(2)
No building or use shall be connected to an existing public or communal
sewage or waste water disposal system unless the building or use is
also served by a public water supply furnished by the Town or by other
public entity whose expenditures are subject to authorization by the
Harvard Town Meeting.
[Added 4-30-1994 ATM by Art. 35]
(3)
Exceptions.
[Added 4-30-1994 ATM by Art. 35]
(a)
The provisions of this Subsection D do not apply to land which is within the boundaries of Fort Devens north of Route 2 and which also lies outside of the one-hundred-year floodplain boundaries of the Nashua River, provided that buildings are connected to the sewage and water supply systems serving Fort Devens.
[Added 3-7-1964 ATM by Art. 28; amended 3-6-1971 ATM by Art. 34; 3-3-1973 ATM by Art. 37]
For a lot situated partly in another municipality, this Bylaw shall apply to the Harvard portion as if the entire lot were in Harvard (see also § 125-21, Permitted uses in AR Districts).
[Added 3-28-1981 ATM by Art. 25]
It is the intent to provide for an optional minor residential subdivision alternative to conventional subdivision development, suitable for some backland tracts. A mini-subdivision is permitted only by special permit (see § 125-46, Special permits), authorized by the Planning Board, subject to the conditions below and in accordance with the provisions of Section 81R of the Subdivision Control Law (G.L. Chapter 41, Section 81R).
A.
The subdivision access right-of-way (called in this section the "accessway")
and the roadway within it may be laid out and built to less exacting
standards than the street and roadway of a conventional subdivision,
provided that the Planning Board finds that the terrain, soil conditions,
and underlying geology are suitable for development with such less
thorough engineering and such reduced standards of construction, and
provided that:
(1)
The accessway, and the roadway within it, shall remain permanently
a private way which shall not be extended, nor shall it be connected
to any other way except where it originates.
(2)
Lots shall be served by the accessway if and only if ownership of
a lot provides membership in a qualified homeowners' association responsible
for maintenance and snow removal on the accessway.[1]
[Amended 3-31-1990 ATM by Art. 18]
(3)
There shall be no shared driveways within the subdivision. The "driveway"
within the accessway is the roadway serving the subdivision and is
not a shared driveway.
(4)
Lots served by the accessway shall meet all of the requirements for
Type 5 lots, except that the special permit may authorize one additional
driveway connection, provided that the lot so connected:
(5)
The accessway provides legal frontage, and thereby access to the
street system, for no more than three lots. The following shall not
be counted as a lot:
(7)
The entire center-line length of the access roadway, measured to
the far side of a terminal turnaround, if any, shall not exceed 700
feet. If there is an access to an approved fire pond having at least
60,000 gallons available drawdown capacity between the street and
the furthest individual driveway connection to the roadway, the length
above may be increased to 1,000 feet.
B.
The hearing for the special permit under this § 125-34, Mini-subdivisions, and the hearing for the subdivision under the Subdivision Control Law shall be combined, and, where hearings by other boards or commissions are required, such hearings may be joint with that of the Planning Board. The Planning Board's Rules and Regulations Relative to Subdivision Control[2] shall include provision for:
(1)
Subdivision access layout and location, and subdivision and individual
driveway (roadway) design and construction compatible with safe vehicular
access, privacy, and the intent and purposes of the Bylaw.
(2)
Orderly transfer of the undivided ownership of the accessway and
driveway (roadway) within it to the qualified homeowners' association,
if there is more than one lot.
[Amended 12-3-2002 STM by Art. 19]
(3)
Minimum separation of accessways from one another, from street intersections,
shared driveways, rights-of-way to more than one lot, and the access
necks of hammerhead and backland lots, both at the street and along
the length of the accessway.[3]

[Added 3-29-2003 ATM by Art. 32[1]]
This section establishes and regulates Open Space and Conservation
Planned Residential Development (OSC-PRD). Development under this
section is pursuant to a special permit granted by the Planning Board.
A.
Purpose and intent. The purpose and intent of the OSC-PRD
provision is to permit high-quality residential development that preserves
open space, water resources, wetlands, habitat, prime agricultural
land, scenic landscapes and natural features, reduces infrastructure
and site development cost, and promotes a diversity of housing opportunities
within the Town, while respecting and enhancing neighborhoods, and
promoting attractive standards of appearance and aesthetics consistent
with Town character.
(1)
A further purpose of the OSC-PRD provision is to reduce the anticipated
negative fiscal impact on the Town associated with conventional residential
development.
(2)
The OSC-PRD provision is designed to encourage the siting of homes
in a manner that clusters units together in well-designed village
settings, on buildable portions of the site, as a distinct alternative
to the more arbitrary siting associated with lot by lot development
typically reflected in plans submitted pursuant to Massachusetts General
Laws Chapter 41, Sections 81K through 81GG, the Subdivision Control
Law.
B.
Applicability. The Planning Board may grant a special
permit for an OSC-PRD on an Agricultural-Residential (AR) zoned tract
of land that is at least 4.5 acres of land area, with definite boundaries
ascertainable from a recorded or registered deed(s) or recorded or
registered plan(s). Existing public and private ways need not constitute
boundaries of the tract, but the area within such ways shall not be
counted in determining tract size.
(1)
Permitted uses in Open Space and Conservation Planned Residential
Development. Permitted uses include the following:
(a)
Single-family detached dwellings.
(b)
Attached units, not to exceed 6 or more units in any single
building.
(c)
Agriculture and horticultural uses including but not limited
to orchards, vineyards, forestry, farming for fruits and vegetables.
(d)
Open space.
(e)
Trails.
(f)
Passive recreation.
(g)
Educational and religious uses and other uses not mentioned
above which are exempt from regulation by zoning under Massachusetts
General Laws Chapter 40A, Section 3.
(h)
Accessory residential/recreational uses (e.g., tennis court,
pool, playground).
C.
Requirements and process for approval. An applicant
who is the owner (or with the permission of the owner) of a 4.5 acre
or larger tract of land in the AR District as described above, may
submit to the Planning Board a plan and application for a special
permit for an OSC-PRD in accordance with the provisions of this section,
excepting the building lots or lot shown on such plans from the lot
area and other dimensional requirements specified in other sections
of this Bylaw. While a subdivision plan is not required to be submitted
in conjunction with the provisions of this section, in the event that
a subdivision plan is being proposed by the applicant, such plan shall
be submitted to the Planning Board in accordance with the Subdivision
Rules and Regulations of the Planning Board.[2]
(1)
Submittal requirements. Prior to the granting of a special permit pursuant to this section, a duly submitted application for said special permit shall be submitted together with a site plan to the Planning Board, in accordance with § 125-38, Site plans, of the Bylaw, and any Site Plan Rules and Regulations adopted by the Planning Board. For purposes of this Bylaw, a landscape architect, architect, land surveyor, and professional engineer must participate in the preparation of such site plan, which shall include the following:
(a)
The location of the proposed development.
(b)
The size of the site in acres.
(c)
The total number of the proposed buildings and/or lots, and
the size of each in square feet.
(d)
The acreage and proposed use of permanent open space.
(e)
A statement on the disposition or manner of ownership of the
proposed open space.
(f)
The lots or areas which are to be used as building areas or
lots, and the lots or areas which are to remain as permanent open
space.
(g)
Lines showing yard and setbacks as required by this Bylaw, within
which dwellings or structures must lie.
(h)
Sufficient detail of proposed built and natural features as described in § 125-35D and § 125-35E to enable the Planning Board to make the required determinations of § 125-35C(3).
(i)
A landscape preservation plan sheet(s) to be included with the
site plan, reflecting the existing, natural features to be preserved
and proposed landscape features and details.
(2)
Submittal of preliminary plan. In order to assist the Planning Board in making a determination, pursuant to § 125-35C(3)(d), that an OSC-PRD is superior to a conventional subdivision development, an applicant must submit a plan of the required form and content standards as a "Preliminary Plan" in accordance with the Massachusetts General Laws Chapter 41, Section 81S and the "Rules and Regulations of the Harvard Planning Board Relative to Subdivision Control." Such plan, although not a formal subdivision plan filing, and submitted for conceptual purposes only, shall include a perimeter survey prepared by a registered land surveyor, location of wetlands delineated by a wetlands specialist, and topography based upon the most recent United States Geological Survey map. The applicant shall demonstrate to the satisfaction of the Board that a subdivision plan, if formally filed, would be buildable without reliance on significant waivers of the subdivision regulations, and without extraordinary engineering techniques. Further, the applicant must demonstrate and provide sufficient evidence, to the satisfaction of the Planning Board, that each of the lots reflected on the "Preliminary Plan" submitted are capable of being served by an individual sewage system that would comply with the regulations of the Board of Health.
(3)
Approval criteria. After notice and a public hearing
in accordance with Massachusetts General Laws Chapter 40A, Section
9, 11, and 15 and after following the procedure outlined in this Bylaw,
the Planning Board may grant such a special permit with any conditions,
safeguards, and limitations, if it determines:
(a)
That the application form and content referred to in § 125-35C(1), herein is properly completed.
(b)
That the site plan referred to in § 125-35C(1) is properly completed.
(c)
That all the other requirements of this Section and Bylaw are
fully met.
(d)
That the design and layout of the proposed OSC-PRD is superior to a conventional subdivision plan in preserving open space for conservation and recreation; that it preserves natural features of the land, and allows more efficient provision of streets, utilities and other public services; and, that it provides a high degree of design quality, based on the criteria and considerations enumerated herein in § 125-35E.
D.
Design criteria. In its consideration of an OSC-PRD,
the Planning Board shall give particular attention to, and shall use
as a basis for its decision, all of the following:
(1)
Lots, streets, off-street parking, sidewalks, pathways and buildings
which achieve the harmonious integration of the proposed development
with surrounding properties.
(2)
Overall layout and design that achieves the best possible relationship
between the proposed development and the land under consideration.
(3)
Appropriately sized and configured open spaces for active or passive
recreation, and where possible, links to adjoining common open space
areas.
(4)
Protection of natural features such as streams, mature trees or clusters
of trees, rock outcrops, bluffs, slopes, high points, views, vistas,
and historic or archeological features.
(5)
Provision of large buffer areas, composed of existing vegetation,
to surround building groupings and building envelope areas, to discourage
site clearing and encourage preservation of existing land cover and
mature vegetation.
(6)
Provision of access to open spaces for the physically handicapped,
elderly, and children.
(7)
Use of open spaces for preserving, enhancing, or providing scenic
vistas; preservation and protection of historic resources.
(8)
Adequacy of provisions for public safety, protection from fire and
flood, and maintenance of public facilities, streets, utilities, and
open space.
E.
Design quality. Project design for an OSC-PRD shall
be reviewed by the Planning Board with input from Town officials,
any review consultant(s), and others as appropriate. This section
is to be interpreted as guidelines to be applied flexibly by the Planning
Board as appropriate to the situation under review, including factors
such as foundation and soil characteristics and other extraordinary
site constraints. While these guidelines apply to all site improvements
and buildings and structures, it is not the intent of this section
to prescribe or proscribe use of materials or methods of construction
regulated by the state building code, but rather to enhance the appearance
of the built environment within an OSC-PRD.
(1)
Building and structure placement. The placement of buildings
and structures in an OSC-PRD should:
(a)
Provide for maximum buffering of buildings and structures to
adjoining properties either within the proposed OSC-PRD or to adjacent
land uses. Such buffering includes, but is not limited to: landscaping,
screening materials, natural barriers, fencing, and related measures.
(b)
Preserve attractive views from major vantage points, especially
from major thoroughfares and residential neighborhoods.
(c)
Avoid regular spacings and building placements that will be
viewed as continuous walls from important vantage points, which may
be identified in an OSC-PRD pre-application conference.
(d)
Avoid the placement of structures, common area facilities, and private space related to individual units in a manner that eclipses views or access to open space areas described in § 125-35K.
(e)
Ensure that 10% of all units are fully accessible to the disabled
and that a majority of units have at least one accessible entrance
and bathroom on a first floor.
(3)
Building appearance and treatment. To the extent not
inconsistent with or pre-empted by the state building code, the following
should be considered as applicable:
(a)
Materials and building treatments that reduce the visibility
of the buildings from distant vantage points, and that are compatible
with backgrounds and surroundings.
(b)
Materials and colors compatible with other quality buildings
of similar scale in the vicinity.
(c)
Green building technologies and materials, wherever possible,
to minimize adverse environmental impacts.
(5)
Landscaping. Landscaping criteria are as follows:
(a)
All open areas, exclusive of areas to remain in an existing
natural state within an OSC-PRD, should be landscaped in an appropriate
manner, utilizing both natural and man-made materials such as indigenous
grasses, trees, shrubs, and attractive paving materials and outdoor
furniture.
(b)
Deciduous trees should be placed along new and existing streets
and ways. Outdoor lighting should be considered in the landscaping
plan, and should be designed to complement both man-made and natural
elements of the OSC-PRD and adjacent areas. Appropriate methods (such
as cutoff shields) should be used to avoid glare, light spillover
onto abutting property.
(c)
Intensive, high-quality landscaping or preservation of existing
vegetation should be provided within the OSC-PRD where it abuts major
streets, existing residential areas, and along internal drives.
(d)
Preservation of existing vegetation or tree-lined areas should
be maintained.
(e)
Parking areas and lots should use landscaping and terracing
to break up large areas of pavement and to enhance residential flavor
and appearance; trees and shrubs should be used to the maximum extent
feasible.
(f)
Features such as shade trees, forest trees, and expansive planting
areas should be preserved and/or introduced along external property
boundaries and on the perimeter of the OSC-PRD itself, to buffer the
site from adjoining parcels.
(6)
Pedestrian amenities and recreation. In this category,
the design should include the following components/characteristics,
appropriate to the land under consideration.
(a)
Accessible pedestrian-oriented features such as walkways, pergolas,
outdoor sitting plazas, landscaped open space, drop-off areas, and
recreational facilities should be emphasized.
(b)
Tree-lined or otherwise appropriately landscaped pedestrian
paths and walkways should link together areas designated as open space
within the site, and wherever possible, to adjoining public areas.
(c)
Passive and active recreational facilities should be of a size
and scale appropriate for the number of units proposed.
F.
Utilities. To the maximum extent feasible, all utilities
should be located underground.
G.
Signage. At each principal entrance to the site, one
sign only shall be permitted; it should be of a maximum signboard
area of three square feet, with content limited to identifying the
name and address of the development.
(1)
Within the development, signs, not to exceed two square-feet each,
of a number and location to be approved as part of the OSC-PRD, may
be permitted for the sole purposes of orientation and direction, and
of identifying common building spaces.
H.
Base development density. The maximum number of dwelling units per acre permitted in an OSC-PRD shall not exceed one unit per 1.50 acres of land area, and in no event exceed the maximum number of lots or dwelling units obtainable under a conventional subdivision plan for the land area under consideration, except as provided in § 125-35I.
I.
Development incentive.
(1)
The Planning Board may authorize an increase in lots or dwelling units up to a maximum of 25% above that allowed under § 125-35H of this Bylaw, provided the following conditions are met:
(a)
The applicant proposes a significant increase in open space
above 50%, and preserves significant natural resources, in the opinion
of Planning Board.
(b)
There is permanent preservation of land devoted or set aside
for agricultural use or other unique preservation strategy, including
preservation of historic structures or barns, or other special features
of the built environment.
|
(If (a) and (b) above are found to be satisfied, in the opinion
of Planning Board, it may authorize a 5% increase in applicable base
density.)
|
(c)
The applicant proposes public improvements or amenities that
result in substantial benefit to the Town and the general public,
provided:
[1]
There are significant improvements to the environmental quality
or condition of the site and its surrounding areas, including a decrease
in stormwater runoff from what would otherwise result from a conventional
subdivision plan.
[2]
There are provisions contributing to off-site public facilities
or environmental improvements beyond those necessary to mitigate the
impacts of the proposed development.
|
(If (c) above is found to be satisfied, in the opinion of Planning
Board, it may authorize a 5% increase in applicable base density.)
|
(d)
The applicant proposes attached dwellings that include a maximum
of two bedrooms per unit, and are developed in the character of a
New England Village style of architecture.
|
(If (d) above is found to be satisfied, in the opinion of Planning
Board, it may authorize a 5% increase in applicable base density.)
|
(e)
Housing units for senior citizens and persons aged 55 years
and over housing is provided.
|
(If (e) above is found to be satisfied, in the opinion of Planning
Board, it may authorize a 5% increase in applicable base density.)
|
(f)
The applicant sets aside 10% or more of lots or dwelling units
on the site for "affordable housing" for purchase or rental by those
with households of low or moderate incomes. Such units must count
toward the Town's Subsidized Housing Inventory, and be in accordance
with the provisions of 760 CMR 45.00, as may be amended. The Planning
Board shall review and approve the actual percentage distribution
of qualifying low versus moderate income units.
|
(If (f) above is found to be satisfied, in the opinion of Planning
Board, it may authorize a 20% increase in applicable base density.)
|
(2)
Standards for on-site affordable units. Housing units set aside as affordable housing, as described in § 125-35I(1)(f), shall have a gross floor area comparable to market-rate units and shall be integrated into the development and not grouped together. When viewed from the exterior, the affordable units shall be indistinguishable from the market-rate units in the same development. The developer shall provide adequate guarantee, acceptable to the Planning Board, to ensure the continued availability and affordability of the units in perpetuity; such guarantee must include recorded deed restrictions, recorded restrictive covenants relative to equity limitation, or other acceptable forms of guarantees. No more than 80% of the building permits for the market-rate units shall be issued within an OSC-PRD until construction has commenced on all the affordable units; no more than 80% of the certificates of occupancy for the market-rate units shall be issued until all of the certificates of occupancy for the affordable units have been issued.
J.
Dimensional requirements. The following provisions shall
apply:
(1)
The Planning Board may waive the minimum requirements for frontage
and/or yard requirements that would normally be applicable to land
within the AR District in order to achieve maximum open space area,
and may permit more than one single or two-family dwelling be located
on a lot in an OSC-PRD, except as provided below.
(2)
The parcel proposed for development must have a minimum of 50 feet
of frontage on a public way or private way which is open to the public.
(3)
Attached units shall contain no more than six units in a single building.
(4)
The minimum distance between clusters of multiple unit dwellings,
shall be 50 feet.
(5)
A minimum width of 150 feet of green area shall be established and
maintained between any property adjacent to the OSC-PRD and the nearest
dwelling unit or units in the OSC.
[Amended 4-2-2005 ATM by Art. 34]
(6)
The minimum setback from internal roads shall be 25 feet.
(7)
The maximum height of proposed buildings shall be 35 feet, and shall
not exceed 2 1/2 stories.
(8)
Except as provided in this Bylaw, any lot in an OSC-PRD shall comply
with any other dimensional requirements of the zoning district in
which it is located.
K.
Common open space. A minimum of 50% of the OSC-PRD parcel
shall be devoted to contiguous open space, completely devoid of any
structure, parking, loading and unloading space, accessways thereto,
or as private yards, patios, or gardens for the exclusive or principal
use by residents of individual dwelling units. To the greatest extent
possible, such open space shall be left in its undisturbed natural
condition or shall be appropriate in size, shape, dimension, location,
and character to assure its use as a conservation area, and where
appropriate, a recreational area, and be a visual and natural amenity
for the development and the Town. The common open space described
herein is in substitution of and supersedes any other reference to
common open space that may be described elsewhere in the Bylaw.
(1)
Open space criteria. The following criteria define open
space, and open space that is considered usable within an OSC-PRD
parcel:
(a)
No more than 25% of common open space in an OSC-PRD shall be
wetlands.
(b)
Unless approved by the Planning Board, common open space shall
not be considered usable if the slope of the finished grade exceeds
33%.
(c)
Unless approved by the Planning Board, the nearest part of the
common open space shall not be more than 300 feet in distance from
the nearest point of any building that it is proposed to serve.
(d)
No common open space shall be considered usable unless it is
compact and contiguous and has no dimension of less than 50 feet.
(e)
All usable open space shall be open to the sky and pervious.
L.
Open space conveyance.
(1)
The common open space shall be conveyed in the following ways as
approved by the Planning Board:
(a)
To a corporation or trust comprising a homeowners association
whose membership includes the owners of all lots or units contained
in the development. The developer shall include in the deed to owners
beneficial rights in said open land, and shall grant a perpetual open
space restriction to the Town of Harvard or a non-profit corporation
or organization over such land to insure that it be kept in an open
state and not be built upon for residential use, or developed for
accessory uses such as parking or roadways. Such restriction 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 open space as the Planning Board may deem appropriate.
(b)
To a non-profit organization, the principal purpose of which
is the conservation of open space. The developer or non-profit organization
shall grant an open space restriction as set forth above.
(c)
To the Town for a park or open space use, subject to the approval
of the Select Board, for management by the Park and Recreation Commission
if a park, otherwise by the Conservation Commission, with a clause
insuring that it be maintained as open space.
[Amended 10-22-2018 STM by Art.
2]
(2)
Multiple conveyance. To provide flexibility, and when
deemed in the public interest, the Planning Board may approve more
than one organization to accept the open space conveyance, particularly
when it is appropriate that a major portion of such land be conveyed
to the Town or a non-profit conservation organization, and another
portion of such land is more appropriately conveyed to an owners association.
M.
Passageways. Private roadways and common driveways shall
be allowed in OSC-PRD parcels. While roadway surface widths may be
narrower than widths associated with a traditional subdivision, the
durability of passageway surfaces and subsurfaces must be comparable
to those in a conventional subdivision.
[Amended 4-2-2005 ATM by Art. 34]
(1)
Criteria for passageways. The following criteria shall
guide the development of these passageways:
(a)
Cleared widths for traveled ways (excluding on-street parking
spaces and passing turnouts) shall not be more than 20 feet or less
than 12 feet. A cleared height of not less than 16 feet above the
entire passageway shall be established and maintained.
(b)
Drainage and surface runoff from all passageways must be suitably
accommodated by an approved drainage system, using best management
practices.
(c)
All OSC-PRD plans shall specify that such passageways will not
be dedicated to the Town, but are to remain private ways; all deeds
or other instruments conveying any portion of land or structure in
an OSC-PRD containing such a passageway(s), shall specify that such
passage way(s) are and shall remain private way(s) in perpetuity;
and
N.
Site improvements. Site improvements specific to an
OSC-PRD are listed below. To assist the Planning Board's evaluation
of site changes and improvements from any OSC-PRD plan, the applicant
shall submit said plan to the Town's Conservation Commission and Board
of Health for review and recommendations to the Planning Board.
(1)
Water supply. Each lot and the development in its entirety
shall be served by water supply systems.
(2)
Sewage disposal. Privately owned and maintained on-site sewage disposal or treatment systems may be approved to serve buildings and lots in an OSC-PRD, if owned, maintained, operated, and monitored by a residents association, notwithstanding the provisions of § 125-32D of this Bylaw, if such treatment facility or system is approved by the Board of Health and in compliance with the requirements of Title 5, 310 CMR 15.00, or approved in accordance with the requirements of 314 CMR 5.00 (the Ground Water Discharge Permit Program). An approved system may be located on land owned in common by the owners of the building lots or residential units within the development.
(3)
Parking. Unless otherwise approved by the Planning Board,
a minimum and maximum of 1.5 off-street parking spaces shall be provided
for each unit, exclusive of spaces within garages. The Planning Board
may also approve, based upon the nature of the development proposed
and exclusive of the 1.5 parking space ratio provided, areas for visitor
parking.
(4)
Storm runoff control. The applicant shall demonstrate
that, as compared with the situation that would exist on the site
without the development, no phase of the proposed OSC-PRD will result
in an increase in the peak rate of storm runoff at the parcel boundary
for the OSC-PRD as a whole for the 25-, 50- and 100-year design storms,
and that there will be no net loss in flood storage capacity for the
100-year design storm. In making such determinations, any state or
local orders or requirements of the Wetlands Protection Act or the
Town's Wetlands Protection Bylaw[3] shall be assumed in the calculations of runoff and flood
storage without the OSC-PRD, but alternative forms of development
shall not be assumed.
(5)
On-site runoff and erosion control. The applicant shall
