Land designated for park or playground purposes shall
not include wetlands, ledge or other land unsuitable for recreation
purposes.
(3)
Any open space, park or playground shall provide at
least 50 feet of continuous frontage on a street. Pedestrianways will
normally be required to provide access from each of the surrounding
streets, if any, to which the open space, park or playground has no
frontage. Such parks and/or playgrounds may be required to have maintenance
provided for by covenants and agreements acceptable to the Board,
until public acquisition is accomplished by the Town, but in no case
longer than three years.
E.
Wetlands protection. The Wetlands Protection Act,
MGL C. 131, § 40, states that "No person shall remove, fill,
dredge or alter any bank, freshwater wetland, beach, dune, flat, creek,
marsh, meadow or swamp bordering on an estuary, creek, river, stream,
pond or lake. . . ., without filing written notice of his intention
to so remove, fill, dredge or alter, including such plans as may be
necessary to describe such proposed activity and its effect on the
environment and without receiving and complying with an order of conditions
and provided all appeal periods have elapsed . . . No such notice
shall be sent before all permits, variances and approvals required
by local bylaw with respect to the proposed activity, which are obtainable
at the time of such notice, have been obtained." The Board may condition
its approval of a definitive plan upon the issuance of an order of
conditions by the Conservation Commission.
A.

shall also be given by the subdivider to the attractiveness of the
street layout in order to obtain the maximum livability and amenity
of the subdivision.
(2)
Provision satisfactory to the Board shall be made
for the proper projection of streets or for access to adjoining property
which is not yet subdivided.
(3)
Subdivisions containing 10 or more lots shall have
at least two noncontiguous street connections with a street or streets,
either existing or shown on an approved subdivision plan, for which
a performance guaranty has been filed.
[Amended 7-5-2000]
(4)
Reserve strips prohibiting access to streets or adjoining
property shall not be permitted, except where, in the opinion of the
Board, such strips shall be in the public interest.
(5)

long as contractual assurance is provided that, upon extension of
the street, the terminated turnaround will be removed and replaced
with loam and appropriate planting. The new applicant shall remove
the temporary turnaround upon placement of the binder course on the
road extension.
[Amended 11-3-1994; 4-3-2003; 3-22-2007; 2-18-2016]
The Planning Board encourages the use of low-impact development (LID) techniques when feasible. Please refer to Chapter 352, Earth Removal Stormwater Advisory Committee Regulations, for LID requirements. If LID techniques are not used, the following regulations apply to conventional drainage systems:
A.
General approach. Storm drains, culverts, swales,
detention basins and related facilities shall be designed to permit
the unimpeded flow of all natural watercourses, to ensure adequate
drainage at all low points along streets, to control erosion and to
intercept stormwater runoff along streets at intervals reasonably
related to the extent and grade of the area being drained. The peak
rate of runoff at the boundaries of the development shall not be increased
from the predevelopment rate during the two-, ten-, twenty-five or
one-hundred-year storm event, unless an increase is authorized by
the Planning Board, following consultation with the Conservation Commission
and consideration of the ability of receiving wetlands or water bodies
to absorb the increase and the consequences of providing detention
capacity. The proposed lot grading shall be shown on the plans so
that the proposed stormwater management system can be properly evaluated.
B.
Design basis.
(2)
All tributary areas shall be assumed to be fully developed in accordance with Chapter 218, Zoning, unless publicly owned or deed restricted. Storm drainage systems shall be designed to handle all runoff water from the tributary watershed. The Rational Formula shall be used to determine pipe sizing for the piped drainage system. The United States Soil Conservation Service (USSCS) TR20 or TR55 Methodology, where applicable, shall be used to determine no net increase in the off-site rate of runoff for detention and infiltration systems. Adequate physical access for maintenance purposes shall be provided to detention and infiltration facilities. Water velocities in pipes and paved gutters shall be between two and 10 feet per second and not more than five feet per second on unpaved surfaces.
C.
Storm sewers.
(1)
All drain pipes shall be at least 12 inches' inside
diameter and made of reinforced concrete conforming with Massachusetts
Department of Public Works specifications for Class III pipe or such
higher class as may be required by the depth of cover, which shall
be not less than 36 inches where the pipe is subject to vehicular
loads. Manhole covers and grates shall be in conformance with Massachusetts
Department of Public Works Specifications 201, designed and placed
so as to cause no hazard to bicycles. No catch basins shall serve
as manholes. Trash racks shall be installed at both ends of all culverts.
(2)
Interceptor drains. Interceptor drains shall be designed
and constructed and incorporated into the drainage system where warranted
by groundwater elevations.
D.
Structures. Catch basins will be required at all low points and on both sides of the roadway on continuous grade at intervals of not more than 300 feet. Drainage patterns at intersections shall be evaluated and catch basins designed and constructed so as to prevent any flooding at the intersection. Any catch basins used shall be at least six feet deep and four feet in diameter (inside measurements), with a thirty-six-inch or greater sump below pipe invert and shall be constructed of precast concrete units. Manholes used shall be at least four feet diameter (inside measurements) and shall be constructed of precast concrete units, with formed inverts (unless waived by the Board to allow the use of concrete blocks). Oil and grease traps shall be installed on all structures that discharge to a resource area as defined by 310 CMR, the Wetlands Protection Act, and where required by the Board. Manhole covers and catch basin grates shall be in conformance with Massachusetts Department of Public Works Section 201, with catch basin grates designed and placed so as to cause no hazard to bicycles. Standard catch basin frames and grates and manhole rims and covers are specified in Part 2, Construction Appendix. Granite curb inlets shall be provided at all catch basins located within the roadway.
E.
Swales. Drainage swales shall have cross-sectional
areas adequate to carry a ten-year storm and be treated as follows:
|
Slopes
(percent)
|
Treatment
| |
|---|---|---|
|
0.75 to 4
|
6 inches of loam seeded
| |
|
4 to 10
|
6 inches' minimum dimension angular stones for
a water depth of 1 foot, with a 12-inch gravel subbase (SSH&B
M 1.03.0 type A)
|
F.
Waterways. Open brooks or tributary ditches which
are to be altered shall be shaped to a cross section and gradient
and provided with stream bottom hardening, all acceptable to the Planning
Board. Safety fencing may be required where important because of slope,
bank instability, stream depth or flow rate or other reasons. Proposed
finished grade for detention basins shall not be more than seven feet
above or below existing grade unless specifically authorized by the
Board in unusual topographic circumstances.
G.
Connections. Proper connections shall be made with
any existing drains in adjacent streets or easements which prove adequate
to accommodate the drainage flow from the subdivision. In the absence
of such facilities or the inadequacy of the same, it shall be the
responsibility of the developer to extend drains from the subdivision
as required to properly dispose of all drainage from said subdivision
in a manner determined to be proper by the Board and to secure for
the Town any necessary drainage rights.
I.
Floodplains.
(1)
District. All subdivision proposals and other proposed new development shall be reviewed to determine whether such proposals will be reasonably safe from flooding. If any part of a subdivision proposal or other new development is located within the Floodplain District established under Chapter 218, Zoning, it shall be reviewed to assure that:
(b)
The proposal is designed consistent with the
need to minimize flood damage.
(c)
All public utilities and facilities, such as
gas, electrical and water systems, shall be located and constructed
to minimize or eliminate flood damage.
(d)

flood) data shall be provided for that portion within the Floodplain
District.
(2)
Identification. All one-hundred-year floodplains will
be calculated and identified on the definitive subdivision where not
identified on the Federal Emergency Management Agency (FEMA) maps.
A.
Water.
(1)
Water shall be supplied to each lot in a subdivision,
if a public water supply is located within 2,500 feet from the center
line of the proposed street, the applicant shall connect all lots
to the public water system. If a public system is not located within
2,500 feet, water main and appurtenances shall be installed in the
new subdivision road for a future connection to a public water supply.
The water main shall be pressure tested at the time of installation.
The applicant shall consult with the Groton Water Department and/or
the West Groton Water Supply District to determine the feasibility
of water being supplied to the subdivision by these municipal entities,
and the plans shall denote the locations of bends, watergates, tees
and hydrants. In the event that such service is provided, the supply
system piping and appurtenances shall be designed according to the
standards and specifications of these companies. Where connection
to a public system is not feasible, evidence shall be submitted to
satisfy the Board of Health requirement that adequate and suitable
supply of potable water is available.
[Amended 5-2-1996; 4-3-2003]
(2)
Water connections. A water connection shall be provided
for each lot in the subdivision. The water connection shall be located
along the frontage of the lot where the lot abuts the right-of-way
of the road.
B.
Electricity and telephone. Electricity, cable television

[Amended 4-3-2003; 10-13-2016]
(a)
When Town water is not available, fire sprinklers in every residential
structure or fire cisterns shall be installed. While the Town of Groton
prefers residential sprinkler systems, the choice of which fire protection
solution to provide is entirely up to the developer.
(b)
When residential sprinklers are selected by the developer, residential
sprinkler systems shall be installed in accordance with National Fire
Protection Association (NFPA) Standard 13D (Standard for the Installation
of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured
Homes), as modified. Residential sprinkler systems shall be accompanied
by an affidavit, stamped by a Registered Professional Fire Protection
Engineer, asserting that each system has been installed in compliance
with the appropriate section of NFPA Standard 13D and is operational,
prior to an occupancy permit being granted.
(c)
When a cistern or cisterns are selected by the developer, the applicant
must submit fire cistern design plans, stamped by a Registered Professional
Fire Protection Engineer, to the Fire Chief for approval. If a proposed
dwelling is not situated within 1,000 feet of a cistern, it shall
be equipped with a residential sprinkler system. All proposed cisterns
shall have a capacity of 50,000 gallons, minimum, available through
the section piping system. Fire cisterns shall conform to the cistern
specifications of the NFPA Standard 1231 (Standard on Water Supplies
for Suburban and Rural Fire Fighting), as modified. New cisterns shall
be accompanied by an affidavit, stamped by a Registered Professional
Fire Protection Engineer, asserting that each cistern has been installed
in compliance with the appropriate section of NFPA Standard 1231.
New cisterns shall be inspected by the Fire Chief and shall be operational
prior to issuance of any building permit.

be provided for each lot in the subdivision. The sewer connection
shall be located along the frontage of the lot where the lot abuts
the right-of-way of the road.
A.
Sidewalks.
(1)
Required locations.
(b)
In addition, public off-street walkways, bikeways
or bridle paths may be required by the Board to provide circulation
or access to schools, playgrounds, parks, shopping, transportation,
open space or community facilities or to break up long blocks or for
such other reason as the Board may determine. Such ways may or may
not be part of normal sidewalk provisions, but they shall not be a
part of any lot in the subdivision and they shall be located in separate
parcels.
(2)
Width and alignment. Sidewalk pavement width shall
be five feet on collector streets and four feet elsewhere and, except
at intersections, shall be separated from the traveled way by not
less than the required shoulder width. Sidewalks shall be constructed

(3)
Construction. Sidewalks shall have a foundation of
eight inches or more of compacted gravel. The paving shall consist
of a binder course, 1 1/2 inches, followed by a finish course,
1 1/2 inches compacted measure, with a one-fourth-inch-per-foot
cross-slope toward the road. Sidewalks shall be cement concrete where
connected to an existing cement concrete sidewalk or where required
by the Board.
B.
Grass plots and slopes. Embankments outside the shoulders
and swales shall be evenly graded and pitched at a rate not steeper
than 2:1 in cut and 3:1 in fill. The Board may require such banks
and all other disturbed areas adjacent to the traveled way to be loamed
and seeded to grass. However, it is suggested that consideration be
given to the surrounding growth and terrain. Road sides should be
made to blend with the woods or natural surroundings that exist, and
plantings in such areas should be chosen accordingly.
C.
Street trees.
(1)
Street trees, not less than 12 feet in height and
2 1/2 inches in diameter and of a species approved by the Planning
Board, after consultation with the Tree Warden, shall be placed on
each side of every street in the subdivision wherever, in the opinion
of the Board, existing woodlands or suitable individual trees are
not retained. A landscaping plan showing street trees, plantings and

Granite curb inlets shall be provided for all catch basins located within the roadway as required in § 381-23, Curbs. If a conventional drainage system is utilized, curbing shall be installed as follows:
[Amended 11-3-1994; 2-18-2016]
(1)
Collector street and minor street. Both sides of the
roads shall have granite curbing with a minimum thickness of six inches
and shall not be less than 18 inches plus or minus one inch in depth.
(2)
Lane. Both sides of the road shall have a bituminous
Cape Cod berm, 12 inches wide with three-inch rise, except that, where
necessitated for traffic control, drainage or maintenance, the Board
may require vertical granite curbs.
E.
Driveway entrances.
[Amended 11-3-1994]
(1)
In order that surface water from roadways shall not
drain onto individual lots, driveway entrances shall be constructed
so that they slope towards the roadway for a minimum distance of four
feet at not less than one inch per foot. All driveway entrances shown
on the definitive plans shall be paved from the gutter line to the
right-of-way line when the binder course and the top course are being
placed on the roadway. Driveway entrances shall be constructed to
the same specifications as the bituminous sidewalk.
(2)
Any changes in driveway entrance location proposed
after approval of the definitive plan shall be submitted to the Board
for review and approval plan prior to construction. When granite curbing
is used, return stones shall be installed at all driveway entrances
prior to placing top course on the roadway.
F.
Monuments.
(1)

or drill holes where a stone wall is the property line. Points-on-line
may be allowed by the Planning Board when lot corners are located
within wetland areas or watercourses. Where not coincident with the
above, such bounds shall be sound granite or reinforced concrete,
not less than three feet long and not less than three inches square,
with a one-half-inch drill hole; any other permanent marker such as
a steel survey marker may be substituted for the bound at the rear
of the lot. Sound granite bounds shall be used at every lot corner
of conservation land or parkland.
[Amended 11-3-1994]
(3)
Monuments shall be installed only after all construction
which would disturb them is completed and shall, in general, have
their top a minimum of three inches above final grade surface. Monuments
shall be installed at lot corners prior to the issuance of an occupancy
permit for the lot unless waived by the Planning Board.
[Amended 4-3-2003]
(4)
The placement and accurate location of these monuments shall be certified by a registered land surveyor and indicated on the as-built plan required at § 381-8C(1)(a).
G.
