structure and at each hydrant to indicate the location and the exact
amount of cut, fill or grade.
G.
Improvements to minimize adverse environmental impact,
if required, shall be installed in accordance with all details as
shown on the approved definitive plan, and all possible measures shall
be taken during construction to minimize erosion and tree removal.
I.
Requirements prior to any road construction. Immediately
prior to any clearing for road construction, the location of the pavement
within the road dedication and the extent of clearing shall be approved
by the Board during a site visit. Under no circumstances shall the
clearing for road construction exceed what is necessary to construct
the road surface, shoulders, drainage ditches (if required) and cut
and fill slopes. If the Board authorizes the movement of the road's
center line off the center line of the road dedication to save specific
trees, the trees to be saved shall be prominently banded so that they
may be observed during road construction.
J.
Driveway stub requirement. Prior to placing the binder
course, a driveway stub built to roadway specifications not less than
20 feet in length (with drainage structures, if required, installed
to facilitate ditch drainage) shall be installed on each lot.
A.
Grading and preparation for pavement. The roadway
shall be graded and prepared as follows:
(1)
Clearing and grubbing (Section 101 of the Standard
Specifications). The paved area and shoulders of each street or way
shall be cleared and grubbed to remove all trees not intended for
preservation, stumps, brush, roots, rocks or boulders and other unsuitable
material which may exist upon the surface.
(2)
Excavation (Section 120 of the Standard Specifications).
The entire area of the roadway shall be excavated to remove all materials
encountered within the paved area and shoulders down to the true surface
of the subgrade, or to suitable material in the areas where unsuitable
materials exist, in preparation for foundations of roadway, sidewalks,
driveways and berms. Materials obtained from the excavation may be
used in fills as needed if they are sampled and tested by an independent
testing laboratory acceptable to the Board or its agent and, in the
opinion of the Board or its agent, the material satisfies the requirements
of Section 150 of the Standard Specifications. Necessary laboratory
testing to determine the suitability of the excavated soil shall be
arranged for and paid for by the applicant.
(3)
Embankment (Section 150 of the Standard Specifications).
When in the opinion of the Board or its agent, suitable material is
not available within the limits of the roadway location to form the
subgrade or subbase, the developer shall obtain suitable additional
material from other sources in accordance with this section, and as
may be approved by the Board or its agent. A certificate of compliance
along with information on the source of the material being used shall
be submitted to the Board or its agent for approval prior to use.
(4)
Grading (Section 170 of the Standard Specifications).
The subgrade surface, 16 1/2 inches below the finished surface
grade in minor streets and 18 inches below the finished surface grade
in major streets, shall be prepared true to the lines, grades and
cross sections given and compacted with a vibratory roller to achieve
95% compaction. The prepared subgrade shall then be proof rolled with
a combined weight of 70,000 pounds to determine that the subgrade
does not contain weak or unsuitable soil. All soft or spongy material
below the subgrade surface shall be removed to a depth determined
by the Board or its agent, and the space thus made shall be filled
with suitable material conforming to Section M 1.02.0. of the Standard
Specifications. Material used shall contain no stones over six inches
in their largest diameter or any other material detrimental to the
subgrade.

(a)
Final compacted thickness for subbase materials
shall be as follows: Subbase shall be eight inches of gravel borrow,
Type b (M 1.03.0) overlaid by four inches of dense graded crushed
stone (M 1.01.7). Gravel borrow material shall be placed in two four-inch
courses on the prepared subgrade and each lift compacted to 95% of
maximum dry density as determined by Standard AASHTO Test Designation
T99 compaction test Method C at optimum moisture content. Depressions
that appear during compaction rolling shall be filled with gravel
borrow and rerolled. The surface of the gravel borrow shall be graded
to the road lines and grades in preparation for the placement of the
dense graded crushed stone material.
(b)
Dense graded crushed stone shall be placed in
one course and compacted as required for the gravel borrow courses.
Final grading, rolling and finishing, including the shaping, trimming,
rolling and finishing of the surface of the subbase prior to placement

subdivision roadways shall conform to the following:
(3)
Once the roadway base course has been placed, the
developer shall maintain this surface until the roadway surface course
is placed and accepted. If the surface course is not placed within
12 months from the date of placing the base course, the developer
shall be responsible for applying a single course surface treatment
consisting of an emulsified asphalt product covered with 3/8 inch
crushed stone. Application rates shall be as follows:
(a)
Emulsion: 0.4 gallons per square yard.
(b)
Cover stone: 22 to 26 pounds per square yard.
Use pretreated stone at the rate of 1.5 to two gallons of MC 70 per
ton. Also use antistrip latex additive. The developer shall be responsible
for ensuring that the roadway is swept between five and 10 days after
the application of the emulsion layer.
(4)
The developer shall be responsible for maintaining
this process until the surface course of bituminous concrete is placed.
(5)
Under no circumstances will the base course be permitted
to winter more than one season without the application of a single
surface course treatment. For subdivisions containing greater than
10 house lots, phasing of the subdivision roadway construction may
be considered by the Board. The applicant shall submit a detailed
plan identifying the proposed phases of roadway construction along
with the preliminary plan for approval by the Planning Board or its
agent.
(6)
Surface courses damaged by the developer or his contractors,
following its acceptance by the Planning Board or its agent, shall
be restored or resurfaced by the developer at his expense.

four horizontal to one vertical (4:1). Where steeper slopes are required,
the slope may be increased to a maximum of 2:1 with the approval of
the Planning Board.
(b)
Cut slopes in earth shall be graded at a maximum
slope of 2:1. Where cuts are made in ledge, other slopes may be determined
with the approval of the Board.
(c)
Where terrain necessitates greater embankment or cut slopes, retaining walls, terracing, fencing or riprap may be used either alone or in combination to provide safety and freedom from maintenance, but must be done in accordance with plans filed and approved by the Board. Guardrails shall be furnished wherever the slope is or greater than two horizontal to one vertical downhill with a vertical drop in grade of four feet or greater, or wherever the slope is three horizontal to one vertical downhill with a vertical drop in grade of 15 feet or greater. Wherever embankments are built in such a way as to require approval by the Board, the developer must furnish to the town duly recorded access easements free of encumbrances for maintenance of the slopes, terraces or retaining walls. All slopes shall be graded, covered with four inches of screened loam and seeded using materials in accordance with Roadside Development Materials (Section M6) of the Standard Specifications and § 300-32 of these rules and regulations.
(2)
Shoulder. Shoulders shall be constructed of dense
graded crushed stone in accordance with the approved plan. Shoulders
shall be a minimum width of three feet as measured from the back of
the berm or edge of pavement. Where trails are to be located adjacent
to the subdivision roadway, the shoulder width shall be extended to
five feet in width and covered with no more than two inches of loam
on the dense graded crushed stone.
(3)
Ditches. Ditches shall be constructed adjacent to
the roadway whenever the center-line profile grade of the roadway
is six inches or more lower than the adjacent topography or when required
to intercept or redirect runoff when construction of the roadway results
in runoff being directed onto the pavement. Ditches shall be constructed
in accordance with the approved plan.
E.
Areas disturbed by construction.
(1)
Loam and suitable vegetative cover approved by the Board shall be placed on all side slopes and other areas disturbed by construction in accordance with § 300-32 unless other types of vegetative or inorganic cover are approved for use or are determined by the Board to be necessary for erosion control. (See § 300-32.)
(2)
Erosion control plan. Before approval of a subdivision,
the developer shall prepare and submit for approval of the Board or
its agent an erosion control plan covering all phases of construction
for the area in which he intends to perform work. This area shall
be specified and may include the portion of work within the right-of-way
or may include all or part of the lots depending on the extent of
work and location of wetlands. The following factors shall be considered
in such a program:
(a)
Construction activities shall be phased so that
construction can be completed rapidly and large areas are not left
bare and exposed for long periods.
(b)
Grading shall be kept at a minimum. Where possible,
existing trees and vegetation shall be protected and retained. Only
undesirable trees shall be removed.
(c)
Drainage shall be maintained by the contractor
during construction. Runoff shall be controlled and conveyed into
storm sewers or other outlets so it will not erode the land or cause
off-site damage.
(d)
Critical areas, including embankments and slopes,
exposed for periods in excess of one month, shall be protected during
construction with mulch or temporary crop covers and with mechanical
measures, such as diversions and prepared outlets.
(e)

be constructed where necessary to detain runoff and to trap sediment
during construction.
(f)
Safe off-site disposal of runoff shall be provided,
including the increased runoff resulting from construction.
(g)
Permanent vegetation and erosion control structures
where necessary shall be installed as soon as possible. In all cases
where riprap is utilized, riprap shall be of a size specified by the
Board or its agent and placed, rather than dumped.
A.
Materials and installation methods.
(1)
Utilities shall be installed in accordance with the
approved plan. No utility mains shall be installed under the pavement
except at intersections, and stubs crossing the street shall be installed
prior to paving. Utility main installation after placement of pavement
shall be approved by the Board and shall conform to Figure 17.[1] Unless otherwise specified, all materials and installation
methods shall conform to the standards of the town.
[1]
Editor's Note: Figure 17 is included at the
end of these regulations.
(2)
All underground utilities and other structures located
within the right-of-way shall be installed in the right-of-way before
completion of the roadway subgrade and before placing of the subbase,
pavement and sidewalk. If the pavement is broken for underground installation
of structures or utilities, pavement repair shall be in conformance
with Figure 17.
(3)
Excavation for structures (Section 140 of the Standard
Specifications). Excavation for structures, including foundations
for drains, sewers, gas and water pipes, walls and other structures
shall be made to the depth indicated on the definitive plan or established
by the Planning Board or its agent as appropriate. Rocks encountered
in trench excavation determined to be Class B rock shall be removed
as directed by the Planning Board or its agent.
B.
Sewerage. On-site sewerage disposal facilities shall
be installed and constructed in conformity with the rules and regulations
of the Board of Health and Title 5, Massachusetts State Environmental
Code. Due consideration should be given to surface and subsurface
soil conditions, drainage and topography in the location of such on-site
facilities.[2]
C.
Gas. If gas is to be installed within a proposed subdivision,
the gas company shall be notified by the developer upon approval of
the definitive plan so that installation of gas mains may be completed
without undue delay and prior to placement of pavement. If excavation
is made after the pavement is completed and inspected, the gas mains
shall be put in a saw-cut trench, backfilled with approved material
and patched in accordance with Figure 17[3] and to the lines, grades and dimensions approved by the
Superintendent of Public Works.
[3]

vertical and/or horizontal separation as approved by the Board. Service
shall be provided to each lot before the subgrade is prepared.
Adequate disposal of surface and subsurface
water shall be provided. Where pipes, manholes and catch basins are
required, they shall be shown on the definitive plan and shall be
in accordance with the following:
A.
Basins, manholes and inlets (Section 201 of the Standard
Specifications). All basins, manholes and inlet structures shall be
constructed in conformance with the latest Massachusetts Department
of Public Works Construction Standards. The standard depth of catch
basins shall be 2 1/2 feet below the invert of the lowest drain.
Manholes shall be constructed to the required depth at each junction
point and shall be as shown on the plan. Basin and inlet grates shall
be of a type approved the Superintendent of Public Works. Inlet structures
susceptible to erosion shall have concrete collars constructed in
conformance with the Standard Specifications. Frames and grates shall
be temporarily set at base course grade and subsequently raised to
finished grade prior to finished paving. Berms shall be installed,
as necessary, to direct the runoff toward the basin. All changes of
direction shall be located off the pavement, and all drain lines,
where possible, shall be located off the pavement.
B.
Culvert, storm drains and sewer pipes. All pipes except
subdrain shall be reinforced concrete pipe Type III and shall be selected
in conformity with the requirements of the Standard Specifications.
All pipe shall be installed in accordance with the size and location

sidewalks shall be separated from the road pavement by a seeded grass
plot a minimum of three feet in width and may be made of either cement
concrete or bituminous concrete.
D.
Reference to Standard Specification. All sidewalk
construction shall be in accordance with the requirements of Section
701, SIDEWALKS AND BITUMINOUS CONCRETE DRIVEWAYS, of the Standard
Specifications, except the cross slope shall be 3/16 of an inch per
foot of width to conform to Massachusetts Architectural Access Board
requirements.
Where bikeways and walkways are required, they shall be constructed in accordance with the specifications for sidewalks above, except for the design standard requirement of § 300-21 above. Where bikeways and walkways intersect with sidewalks, leveling areas shall be provided. These leveling areas shall be shown in detail on the definitive plan for the subdivision. All bikeways shall conform to current Federal Highway Administration standards. Where trails have been relocated or otherwise disturbed, the developer shall ensure that they are readily passable on foot or horseback. They shall have solid footing, be level from side to side, neither ascend nor descend at an excessive slope and be clear of obstructions and other hazards.
A.
Granite curbing. The board may specify that battered
granite curbs with a five-inch face set in concrete with the dimensions
given for granite curb (Section M9.04.1) Type VB4 in the Standard
Specifications be provided in the following locations and be installed
in accordance with the construction methods outlined under Section
501, CURB, CURB INLETS, CURB CORNERS AND EDGING, of the Standard Specifications.
(1)
Intersections - subdivisions. Granite curbing shall
be provided at intersections along the paving edge the distance of
arcs of the curves plus a straight section at each end of six feet,
in accordance with the approved plan.
(2)
Intersections - major roads. Granite curbing shall
be provided at intersections where the Planning Board or its agents
deem it necessary.
(3)
Traffic islands and medians. Granite curbing shall
be provided at raised traffic islands and medians.
B.
Bituminous concrete berm. Where required to control
surface runoff and granite curbing has not been required, the Board
may require the edges of all minor and major streets to be provided
with a bituminous concrete berm. Bituminous concrete berms shall be
constructed in conformance with the dimensions and at the locations
shown on the plans. Bituminous concrete berms shall be constructed
monolithically in conjunction with top course paving operations, by
means of an approved attachment to the paving machine, designed specifically
for that purpose. Upon formation, bituminous concrete berms shall
be hand rolled for compaction. Bituminous concrete berms formed by
extrusion machines will not be approved or accepted. The bituminous
concrete berm shall be constructed in accordance with the approved
plan and in accordance with the requirements of Section 500, CURB
AND EDGING, of the Standard Specifications.
A.
Guard fences, rails and walls shall be installed wherever
determined necessary by the Board or its agent to provide needed protection
to the public and when slopes are three to one (3:1) or greater or
have a vertical drop in excess of four feet. When provided, they shall
be constructed in accordance with the approved plans and the current
standards of the American Association of State Highway and Transportation
Officials (AASHTO) Roadside Design Guide. Construction details of
all fences, rails and walls shall be shown on the definitive plan
for the subdivision. Whenever possible, such fences, rails and walls
shall be of a rustic nature to blend with the character of the town.
B.
Stone wall appearance.
(1)
Stone walls in New England and in Boxford are a proud
hallmark of our heritage and are a fundamental quality of the charm
and special nature of Boxford.
(2)
Stone walls shall be simple and modest. They are usually
three feet in height and give the viewer the impression that they
are almost naturally part of the landscape.
(3)
Boxford stone walls are part of a rural farming community.
They are not to be suggestive of a formal massive estate entrance
constructed in such a manner so that they look as if they are finished
works with uniform dimensions and surfaces and smooth lines.
(4)
Stone walls shall be constructed (or at least appear
so) by carefully piling the stones without visible mortar. Here again
the element of simplicity is present, in fact properly piling the
stone requires careful planning, especially if the wall is to have
the necessary amount of structural integrity to withstand the pressure
of plowed snow. Boxford stone walls shall not have bronze or metallic
plaques embedded in the surface.
(5)
The ends of a stone wall should be as simple and natural
as the wall itself. Importantly, at openings for driveways or roads,
the stone wall should not be perfectly curved to parallel the road
flair, which would be characteristic of a suburban development.
Retaining walls when required shall be constructed
of field stone and mortar and shall be finished with a concrete cap
to prevent deterioration. See Figure No. 15.[1]
[1]
Editor's Note: Figure 15 is included at the
end of these regulations.
A.
Street trees of nursery stock conforming to current
standards of the American Association of Nurserymen of the species
approved by the Tree Warden and/or the Board shall be planted on each
side of each street in a subdivision, except where the definitive
plan shows trees to be retained which are healthy and adequate, which
shall be retained. Street trees shall be located outside of the right-of-way
or at the discretion of the Board within the unpaved portion of the
right-of-way approximately at forty-foot intervals; shall be at least
12 feet in height; two inches in caliper measured four feet above
the approved grade, unless otherwise required by the Tree Warden and/or
the Board; and be not closer than five feet nor more than 20 feet
to said right-of-way line unless otherwise approved by the Board.
B.
All retained street trees shall be clear of any branches
protruding into the shoulder and road area from the approved grade
level to a point seven feet above ground level.
D.
Planting methods, including wrapping, staking and
guying, shall be in accordance with Section 771, PLANTING TREES, SHRUBS
AND GROUND COVER, of the Standard Specifications.
E.
All reasonable care shall be exercised to preserve the trees in the subdivision in accordance with § 300-15.
F.
The developer will be liable for all trees so planted
as to their erectness and good health after planting and until the
release of all guaranties.
A.
Monuments shall be installed on the street right-of-way
lines at all points of intersections of streets lines and at all points
of curvature and at all points of change in direction. Iron rods shall
be placed where lot lines intersect the street right-of-way line.
B.
Monuments shall be a standard permanent granite conforming
to granite bounds (M9.04.9) and of not less than four feet in length
and not less than six inches in width and breadth and shall have a
hole 1/2 inch in diameter and 1 1/2 inches deep, drilled in the
center of the top surface.
C.
Monuments shall be installed in accordance with Section
710, BOUNDS, of the Standard Specifications at the time of final surface
grading with the top six inches above final grade surface.
D.
The placement and accurate location of these monuments
and markers shall be certified by a registered land surveyor and properly
located on the as-built acceptance plans.
A.
From the time of rough grading until such time as
each street is accepted by the town as a public way, the sign posts
at the intersection of such street with any other street shall have
affixed thereto a sign designating such street as a private way.
B.
Street signs for each intersecting street shall be
installed at each intersection to conform to those used the Boxford
Department of Public Works.
C.
No street sign, temporary or permanent, shall be installed
showing a name other than the one approved by the Board.
D.
Subdivision signs may be temporarily posted for a
period not to exceed two years from the sale of the first lot within
that subdivision. After that period, the sign must removed. The Inspector
of Buildings will police such action.
A.
Where required by the Board, street and pedestrian
lighting shall be installed to conform to the type and style in general
use in the Town of Boxford unless otherwise specified by the Board,
and no lighting shall be installed except as approved by the Board.
It shall be located on a suitable post, which may be a concrete, aluminum
or square section of creosote-treated wood having a height of 25 feet
or more as approved by the Board.

Street and pedestrian light stanchions shall be located
in the grass plot at such intervals as required by the Board and shall
be installed in accord with the procedure required by the Massachusetts
Electric Company.
C.
All luminaries shall be of the indirect, shielded
type.
Where required by the Board, a fire alarm system shall be installed within the subdivision to conform with the specifications of the Fire Department and shall be located as specified on the definitive plan unless otherwise specified by the Board. (See § 300-19.)
No lot shall be considered complete until all
stumps, brush, roots and like material and all trees, rocks and boulders
not intended for preservation by the applicant shall have been removed
and disposed of in a manner and place satisfactory to the Board. Any
fire hazard shall be removed promptly to the satisfaction of the Fire
Chief. This section does not authorize violation of the soil stripping
provision of the Zoning Bylaw,[1] as it does not authorize the removal, including severing
and stripping of soil loam, sand or gravel on such lot.
Any subdivision located in any part within an
area subject to flooding shall comply with the following:
A.
Subdivision design shall be consistent with the need
to minimize flood damage within the flood-prone area, through use
of open space reservation, street profile design and drainage.
B.
All public utilities and facilities, such as sewer,
gas, electrical and water systems, shall be located and constructed
to minimize or eliminate flood damage.
C.
No increase in off-site discharge shall be permitted.
For the purpose of protecting the safety, convenience
and welfare of the town's inhabitants, for the provision of adequate
access to all of the lots in a subdivision by means that will be safe
and convenient for travel, for reducing the danger to life and limb
in the operation of motor vehicles, for securing safety in the case
of fire, flood, panic and other emergencies, under the authority of
MGL c. 41, § 81-M, as amended, the applicant or his successor
shall provide for the proper maintenance and repair of improvements
during the period of construction and until the town votes to accept
such improvements.
The applicant shall provide competent supervision
during the development of his subdivision. If at any time it becomes
apparent to the Superintendent of Public Works that the supervision
is not satisfactory, he may request of the Board that it order the
discontinuance of the development until competent supervision is provided.
If the proposed development contains hazardous
materials or underground storage tank(s),[1] the location and extent shall be shown on the subdivision
plans. All remedial work required shall be performed in compliance
with all local, state and federal laws.
