A.
The entire area of each street right-of-way shall
be cleared of all stumps, brush, roots, bounders, like material, and
all trees not intended for preservation. No trees may be preserved
within 10 feet of the traveled way.
B.
The full length and width of the traveled way shall
be excavated or filled, as necessary, to a depth of at least 18 inches
below the finished surface as shown on the profile. However, if the
soil is soft or spongy, or contains undesirable material such as clay,
sand pockets, peat or any other material detrimental to the subgrade,
such material shall be removed and replaced with suitable well-compacted
material. In areas where the depth to groundwater from the proposed
road grade is 36 inches or less, road underdrains shall be constructed
as sown on Figure 12.[1]
[1]
Editor's Note: Figure 12 is included at the end of this chapter.
C.
All parts of the traveled way shall be brought to
a finished grade as shown on the profile of the definitive plan with
at least the top 18 inches consisting of well-compacted gravel to
a width of at least 30 feet, to be located centrally with the road
right-of-way. At each side there shall be a shoulder two feet wide,
also consisting of well-compacted binding gravel at least 18 inches
deep. The gravel shall be spread and rolled in three layers of about
six inches each. All stones larger than four inches shall be removed
before layers are rolled. Rolling shall be done with a self-propelled
roller weighing not less than eight tons and shall continue until
a firm even surface, true to line and grade, is obtained.
D.
Paving.
(1)
Where, in the opinion of the Planning Board, the anticipated
volume of traffic or grades of the finished traveled way or other
conditions require it, roads shall be paved in accordance with the
specifications and standards of the Town of Dalton Highway Department.
(2)
All driveways provided by the subdivider shall be
paved from the street line to the right-of-way line.
(3)
The subdivider shall repair any settlement or imperfections
in this work during a period of one year from the date of final installation
of pavement.
A.
Adequate disposal of surface water shall be provided.
Catch basins and culverts shall be built in conformity with the specifications
of the Town of Dalton Highway Department on both sides of the roadway
on continuous grades at intervals of not more than 300 feet, at low
points and sags in the roadway, and near the corners of the roadway
at intersecting streets.
B.
The subdivider may be required by the Planning Board
to carry away by pipe or open ditch any spring or surface water that
may exist either previous to or as a result of the subdivision. Such
drainage facilities shall be located in the street right-of-way where
feasible, or in perpetual unobstructed easements of appropriate width.
C.
A culvert or other drainage facility shall, in each
case be large enough to accommodate potential runoff from its entire
upstream drainage area, whether inside or outside the subdivision.
The Town of Dalton Highway Department shall approve the design and
size of the facility based on anticipated runoff from a ten-year storm
under conditions of total potential development permitted by the Zoning
Bylaw in the watershed.
D.
The subdivider's engineer shall study the effect of
each subdivision on the existing downstream drainage facilities outside
the area of the subdivision. This study shall be reviewed by the Select
Board and/or Highway Superintendent. Where it is anticipated that
the additional runoff incidental to the development of the subdivision
will overload any existing downstream drainage facility, the Planning
Board shall not approve the subdivision until provision has been made
for the improvements of said condition.
A.
All utility wiring as well as transformers and other
distribution and control devices shall be buried in the ground unless,
in the opinion of the Planning Board, estimates made by utility companies
indicate that an unreasonable cost would be imposed on the subdivider.
B.
Utility wires or cables, other than those going across
roads and those leading directly to individual consumer installations,
shall be buried within the road right-of-way in a strip 4 1/2
feet wide running parallel to the edge of the right-of-way, unless
soil or terrain require a different location. No wires or cables may
be installed under the traveled portion of the right-of-way except
where crossing a road, and there, ducts must be used.
C.
Copies of all plans showing the location of all buried
wires or cables are to be presented by the subdivider before any paving
of roads is started, one copy to be filed with the Planning Board,
one with the Town Clerk and one with the Select Board.
D.
If underground installation is found by the Planning Board to be unreasonably costly to the developer, all overhead wires and related equipment shall be centered as much as possible on rear or side lot lines, unless this provision is waived by the Planning Board. Easements shall be provided as outlined in § 501-11.
E.
Poles and associated structures used for streetlighting
shall be installed.
A.
Permanent monuments shall be installed at all road
intersections, at all points of change in the direction or curvature
of roads, and at other points where, in the opinion of the Planning
Board, permanent monuments may be necessary.
B.
The permanent monuments shall be of 3,000 psi reinforced
concrete, and shall measure six inches by six inches by five feet
and shall have a suitable reference marker on the top. (See Figure
11.)[1]
[1]
Editor's Note: Figure 11 is included at the end of this chapter.
C.
No permanent monuments shall be installed until all
construction that would destroy or disturb them is completed. The
tops of monuments shall be set to the established grades, and backfill
material shall be carefully placed around each monument and thoroughly
tamped.
Posts with signs carrying the names of the streets
or other ways shall be installed at the beginning of all new ways
and at the intersection of all ways whether existing or proposed within
a subdivision. There shall be at least one such sign and signpost
at each intersection. Said signs and signposts shall follow the specifications
of the Town of Dalton Highway Department.
Curbing shall be constructed on both sides of
the street. Sidewalks shall be constructed on both sides of the street
in all zones except R-1 unless deemed otherwise by the Planning Board.
Construction shall be in accordance with the specifications and standards
of the Town of Dalton Highway Department.
All construction work under these regulations shall conform to the requirements and standards of the Town of Dalton Highway Department and to the specifications for highways which may be adopted by the Select Board. Construction specifications and standards as shown on Figures 1 to 12 inclusive are made a part of these regulations.[1] Unless otherwise specified, all work and materials used
in the work to be done shall conform to the requirements of "The Commonwealth
of Massachusetts. Department of Public Works. Standard Specifications
for Highways. Bridges and Waterways" 1973 Edition, or any amendment
thereof, addition thereto, or substitution therefor.

Editor's Note: Figures 1 to 12 are included at the end of this chapter.
A.
The developer's engineer shall make periodic site
inspections to ensure that the work is being done in accordance with
the approved definitive plan and these subdivision regulations. The
developer's engineer shall submit written monthly reports to the Planning
Board when the work is in progress. In addition, the Planning Board
shall be notified by the subdivider prior to the commencement of each
of the major phases of construction, and as each phase is completed,
it shall be approved by the Planning Board prior to starting the work
in the succeeding phase.
B.
In addition, the Town will retain its own consulting
engineer to review the various phases of construction and the developer's
engineer's progress reports. The costs of the Town's consulting engineer
shall be borne by the developer. The estimated costs shall be negotiated
between the developer and the Planning Board prior to the final approval
of the plan. The negotiated amount shall be placed in an escrow account
to be drawn upon as needed to pay the Town's engineer as bills are
submitted. Any unexpended balance plus interest accrued shall be refunded
to the developer at the completion of the project.
A.
Unless at least two shade trees per lot, of species
approved by the Dalton Tree Warden and having a diameter of at least
one inch at a point one foot above the finished grade, exist and can
be preserved within 20 feet of the edge of the right-of-way, the subdivider
shall procure and plant at least two nursery-grown shade trees per
lot within 20 feet of the edge of the right-of-way, said trees to
be species recommended by the Dalton Tree Warden and measuring at
least one inch in diameter at a point approximately four feet above
the root collar.
B.
The planting season shall be from April 15 to June
15 and from September 1 to October 15. New trees and existing trees
that die within one year from the date of planting, or from the date
of acceptance of the street for existing trees, shall be replaced
by the subdivider. In the event an existing tree dies within the three-year
period, it shall be cut down and removed by the subdivider and the
stump shall be cut to a point at least 12 inches below ground level.
Its replacement shall be as described for a new tree. An existing
tree on a new lot that is within 20 feet of the street right-of-way
shall be deemed to be the same as if it were on the tree line established
by the Dalton Tree Warden.
C.
If trees are not planted at the time of completion
of all other work in the development, an escrow agreement (Form F[1]) shall be executed providing for the planting of trees.
[1]
Editor's Note: Form F is included at the end of this chapter.
A.
Topsoil shall be placed and thoroughly compacted to
a minimum depth of four inches on side slopes within the road right-of-way
and over land exposed during grading operations. Grading shall be
done carefully to avoid unnecessary damage to existing vegetation.
Except when necessary to conform to road, driveway and drainage standards
or to eliminate blind intersections or poor sight lines at curves,
major earth movements shall be avoided.
B.
Drainage ditches wherever possible shall be graded
to resemble natural streams.
C.
Topsoil shall not be removed from the site except
where so authorized by the Planning Board.
To prevent erosion, shoulders and graded slopes
shall be seeded on completion or planted with shrubs or similar approved
landscape treatments. Seed and planting specifications shall be in
accordance with Section H-3 of the Standard Specifications for Highways
and Bridges of the Commonwealth. All new planting within the street
right-of-way shall be with good nursery stock and will be subject
to inspection after one year. Trees, shrubs or grass found by the
Planning Board to be dead or in an unsatisfactory condition may be
required to be replaced by the subdivider.
A.
The slopes of the area from the right-of-way to the
finished grade of abutting lots shall not be greater than at a rate
of three feet horizontal to one foot vertical.
B.
The slope along rear property lines and abutting lots
shall not be greater than at a rate of three feet horizontal to one
foot vertical and shall be graded to prevent drainage runoff onto
abutting lots. Where necessary, swales shall be constructed to carry
away drainage runoff.
C.
Whenever the approved street grade differs substantially
from the grade of adjacent land, or where otherwise necessary for
public safety, the subdivider shall be required to erect retaining
walls or guardrails of the type and size approved by the Planning
Board, in the interest of public safety.
The entire area of the subdivision must be cleaned
up so as to leave a neat and orderly appearance from debris and other
objectionable materials. The subdivider shall be responsible for providing
thoroughly clean and unsilted storm drain lines within the subdivision.
The subdivider shall submit to the Town of Dalton
Highway Department record plans showing the roadways, sewerage and
drainage facilities as built. The record plan shall include ties to
sewer and drainage manholes, catch basins, water valves and sewer
and water house services.
