for a distance of not greater than 17 feet either side of the center
line. A greater width may be required at corners and on the inside
of curves for visibility. Clearance of trees beyond a total width
of 34 feet or more than one foot beyond the slope at cuts or fills
is not permitted, except for the construction of sidewalks or utilities.
C.
Non-frost-susceptible soil. All fill and undisturbed soil shall be
non-frost-susceptible, to a minimum depth of three feet below the
finished pavement grade. Non-frost-susceptible soil shall mean soil
that shall not contain more than 3% material that passes through the
No. 200 sieve and, in addition, shall not include any material that
is larger than three inches in size.
D.
Subgrade preparation. All existing material shall be removed for

shall be prepared to required lines and grades, and all fill shall
be constructed in six-inch lifts. The subgrade shall be compacted
to a minimum of 92% and 95% of maximum dry unit weight and at or near
optimum moisture content as determined by ASTM D-1557-66T, Method
D. Preparation of the subgrade shall be approved by the Planning Board's

Works Type I-1 binder course and 1 1/2 inches of top course to
lines and grades as required. The pavement shall be compacted to a
minimum of 95% of laboratory density, and surface irregularities greater
than 1/4 inch as measured with a ten-foot straightedge shall be corrected
as determined by the Planning Board's engineer.
H.
Truck tickets. Printed truck tickets showing the weight and mix of
the bituminous paving material at the batch plant plus the date and
time shall be turned over to the Planning Board's engineer at the
time of each delivery.
I.
Months and conditions during which bituminous material shall not
be laid. No bituminous material shall be laid between November 15
and April 15 of any calendar year. No such material shall be laid
when the ambient temperature drops below 40° or when it is raining.
A waiver or subsequent modification of the definitive plan shall be
required to pave outside of these dates. The Planning Board's engineer
cannot provide a waiver. In the event that such paving occurs, an
applicant shall be required to remove the pavement and lay new pavement
or provide adequate surety to guarantee that the pavement shall survive
for its expected useful life or be replaced.
J.
Dust and debris control. The applicant shall promptly remove gravel,
sand, dirt and/or any debris generated by the subdivision project
from all Town ways. The applicant shall provide and obtain approval
from the Planning Board for dust control measures and then conform
to those measures during all phases of subdivision construction.
K.
Driveway entrances. A driveway entrance proposed within the way lines
shall be installed at the time of the road construction and in accordance
with the requirements of the road construction. To prevent surface
water from roadways from draining onto individual lots, driveway entrances
shall be constructed such that they slope toward the roadway for a
minimum distance of four feet at a slope of not less than one inch
per foot. Adequate means shall be taken to prevent water from draining
onto the roadway in such quantities as to erode the roadway or to
form ice buildup in the winter months. Adequate means shall also be
taken to prevent any driveway from blocking natural drainage via a
culvert or pipe. Driveways, including existing driveways both within
and outside of the subdivision, shall not be within 75 feet of the
intersection of the center lines of intersecting streets.
L.
Street signs. Street signs shall be erected as required before construction
of the roadway begins. The cost of the sign and its installation shall
be borne by the applicant and shall conform to the street sign standard
used by the Town of Norwell and shall be installed under the direction
of the Planning Board or Highway Surveyor. The Planning Board shall
approve the name of any new subdivision street.
M.
Not an accepted street. Streets within a subdivision that have not
yet been accepted by the Town as public ways shall have conspicuously
posted, by and at the expense of the applicant, signs at intersections,
suitable to the Highway Surveyor, stating: "Private Way." The latter
sign shall be a separate sign that is attached before the signage
that sets forth the name of the way, suitable for easy removal when
and if the way is accepted by the Town as a public way.
N.
Advertisement signs. Signs may be posted within a subdivision advertising
lots or houses for sale only in accordance with the following:
(1)
Signs shall be no larger than six square feet and not longer
than three feet in either direction or higher than six feet at the
highest point above the average surrounding grade.
(2)
Signs shall not fluoresce or glow or be lighted in any manner.
(3)
A sketch of any proposed sign or signs shall be filed with the
Planning Board prior to erection.
(4)
No sign may be erected or displayed until written approval for
each such sign is obtained from the Planning Board. No permit is valid
for longer than two years. A permit may be renewed by the Planning
Board.
O.
Monuments. Stone or approved reinforced concrete bounds shall be
placed on both sides of the street at all angle points, at the beginning
and end of all curves, and at all intersections of streets. Bounds
shall be not less than four feet in length and not less than six inches
in width and breadth. Way bounds shall be capped with bronze inserts.
No permanent monuments or bounds shall be installed until all construction,
which could destroy or disturb the monuments or bounds, is completed.
The top of the bounds shall be set to finished grade and be set by
a registered professional or registered land surveyor who shall certify
in writing that they conform to the endorsed definitive plan.
P.
Prevention of water pollution.
(1)
During the performance of work within the subdivision, the applicant
shall take sufficient precautions during construction to avoid contaminating
water in adjacent streams or bodies of water. All earthwork, grading,
moving of equipment, water control in foundation areas, and other
operations likely to create silting shall be conducted to avoid or
minimize pollution in adjacent streams and bodies of water. Water
used for any purpose whatsoever by the applicant, which has become
contaminated with oil, bitumen, salt or other contaminants, shall
be so discharged so as to avoid affecting nearby waters. Under no
circumstances shall the applicant discharge contaminants directly
into any adjacent stream or bodies of water.
(2)
When the applicant uses water from natural sources for any construction-related
operations, intake methods shall be such as to avoid contaminating
the source of supply and maintain adequate downstream flow when the
source is a stream. Violations will result in termination of work
until the impacted area is restored.
Q.
Barricades and warning signs. The applicant shall furnish, erect
and maintain adequate warning and guide signs, traffic signs, safety
lighting, barricades and barrier fences for the safe flow of traffic
and protection of all life and limb.
R.
Protection and restoration of property. The applicant shall preserve
and protect from injury all property either public or private adjacent
to the subdivision, and he shall be responsible for and repair any
and all damage and injury thereto, arising out of or in consequence
of any act of omission, neglect or misconduct in the execution of
the work, or in consequence of the non-execution thereof by the applicant
in the performance of the work prior to completion and acceptance
thereof.
S.
Cleanup. Upon completion of all work on the grounds, the applicant
shall remove from the streets and lots all temporary structures, surplus
material and rubbish, and shall leave the work in a neat and orderly
condition. All disturbed areas shall be properly graded, topsoiled
to a minimum depth of six inches, limed, fertilized and seeded to
satisfactory established growth including a minimum of three necessary
mowings.
