A.
It shall be the responsibility of the developer to
ensure that all public improvements are centrally located within rights-of-way
or easements. The developer shall construct each highway in accordance
with the particular specifications for its designated classification,
as well as in accordance with the specifications common to all classifications.
B.
The developer shall establish and clearly mark on
the site the limits of highway right-of-way and easements, the center
line and grades of the road pavement and the location and elevation
of drainage and drainage structures in accordance with the approved
plans. Such markers shall be maintained at the developer's expense
until the construction of all required improvements within the right-of-way
limits has been completed, inspected and approved by the Highway Superintendent
and the Town Engineer.
C.
If the Highway Superintendent finds that conditions
in the field will require major modifications of a plat or plan approved
by the Planning Board, the Highway Superintendent shall have the authority,
at his option, to require the developer to submit a revised plan for
Planning Board review.
A.
All required erosion and siltation control measures
on the approved plat or site plan or as otherwise required shall be
fully installed prior to the start of construction of any improvements.
C.
All rocks, boulders, brush, roots and stumps shall
be grubbed, excavated and removed from the cleared areas. All such
materials shall be disposed of in an approved manner.
D.
Sight easements shall be cleared prior to issuance
of building permits.
A.
The developer shall complete the shaping of the highway
right-of-way, streams, ditches and easement areas to the line and
grade shown on the approved plan and as otherwise may be directed
by the Highway Superintendent or the Town Engineer. All unsuitable
or unstable materials shall be completely excavated and removed from
the right-of-way, and all rock, or boulders larger than six inches
in diameter, shall be excavated at least eight inches below the subgrade
of road pavement, drainage or drainage structures, curbs and sidewalks.
B.
Where fills are necessary to complete the required
line and grade, the materials incorporated in the work shall be acceptable
to the Highway Superintendent or the Town Engineer. Material shall
be placed in lifts not exceeding six inches in loose depth, and each
lift shall be compacted to 95% standard proctor maximum density by
rolling with a smooth drum vibratory, sheepsfoot, pneumatic-tired
or padded wheel roller, or by impact rammer or vibrator equipment
in areas inaccessible to power rollers. All compaction shall continue
until the fills are firm and unyielding. Special care shall be exercised
in placing and compacting material immediately adjacent to pipes in
order to avoid damage to the pipe and to prevent pipe misalignment.
C.
The rough grade of the pavement, curb and sidewalk
areas shall be completed to within one inch above or below true subgrade
as shown on the approved cross section of the right-of-way improvement.
D.
"Rock" is defined as being sandstone, limestone, granite,
quartzite, slate, shale or similar material in masses more than 20
cubic feet in volume, or in ledges four inches or more in thickness,
which may or may not require blasting for its practical and effective
removal. Should rock be encountered in two or more ledges, each ledge
being not less than three inches in thickness and with interlying
strata of earth, clay or gravel not more than 12 inches thick in each
stratum, the entire volume between the top of the ledge and the bottom
ledge will be classified as rock.
E.
When rock is encountered during excavation, the developer
shall excavate as required for the construction of the proposed project
as shown on the approved construction plans or subdivision plat, and
in accordance with the following requirements:
(1)
It shall be the responsibility of the developer
to employ the most efficient method or methods in removing the rock
so encountered. He will not be permitted to use archaic or inefficient
methods.
(2)
When blasting is required to facilitate removal
of rock in excavations, all operations pertaining thereto shall be
carried out only under the direct, personal supervision of a person
who is knowledgeable in the handling and use of explosive in this
class of work and who shall possess a valid blasters certificate of
competence, Class I or II, issued by the State of New York, Department
of Labor, Division of Safety and Health.
(3)
The developer shall take all precautions necessary
to protect persons and property whenever and wherever blasting is
being carried out and he shall be responsible for any and all damage
or damages resulting therefrom. The cost of repairing all damages
caused by blasting shall be borne by the developer. See also A197-90C,
Insurance.
(4)
No blasting shall be carried out within 50 feet
of any pipe, conduit or other structure already in place. Notification
as to time and place of blasting shall be provided to all proper authorities,
including the Highway Superintendent and the Town Engineer.
(5)
The face of all rock excavation for roadways,
where the face is in excess of four vertical feet, shall be presplit.
(6)
Excavated rock shall be disposed of in an approved
manner.
A.
After completion of the rough grade and prior to placing
the foundation course, the subgrade shall be shaped to line and grade
and compacted to minimum 95% of standard proctor maximum density with
an approved self-propelled roller weighing not less than 10 tons.
All hollows and depressions which develop under rolling shall be filled
with acceptable granular material and again rolled, and this process
shall be continued until no depressions develop. The subgrade shall
not be muddy, frozen or otherwise unsatisfactory when the foundation
course is laid upon it.
B.
Any soft or unstable portions of the subgrade which
develop under the roller shall be completely excavated and removed
from the right-of-way and shall be replaced with acceptable granular
material and the area regraded and compacted as above.
A.
Before fine grading subgrade or construction of curbs
and sidewalks is started, all storm and sanitary sewers and all utilities,
including but not limited to, house connections, hydrants, service
lines, gas services, telephone, electric and cable conduits and roof/footing
drains shall have been installed, and all fill and backfill shall
have been thoroughly compacted to the satisfaction of the Highway
Superintendent.
B.
The subgrade shall conform to the prescribed width
of pavement and shall extend equidistant from the center line of the
road and shall conform to the typical cross section of the road and
the approved line and grade.
C.
The subgrade shall be fine graded with a motorized
grader and recompacted to the satisfaction of the Highway Superintendent
and the Town Engineer.
A.
The foundation course shall consist of two gradations.
(1)
The lower layer shall consist of approved run-of-bank
gravel, crusher-run stone or crusher-run gravel. All materials acceptable
for this layer shall be hard, durable and sound and shall be well
graded from coarse to fine. One hundred percent by weight shall pass
through a four-inch square hole, not less than 30% by weight shall
pass the one-fourth-inch square sieve, not more than 70% by weight
shall pass the No. 40 mesh sieve and not more than 10% by weight shall
pass the No. 200 mesh sieve.
(2)
The maximum particle size permitted in the three-inch
graded gravel layer shall not exceed such size as will pass through
a two-inch square hole. Thirty percent to 65%, by weight, shall pass
the one-fourth square sieve and not more than 10% by weight shall
pass the No. 200 mesh sieve.
B.
After the subgrade and all concrete curbs (if used)
have been constructed to the satisfaction of the Highway Superintendent,
the developer shall furnish and place the foundation course. The foundation
course materials shall be placed on the finished subgrade and shall
be compacted to minimum 95% standard proctor maximum density by rolling
with a self-propelled ten-ton roller. Water shall be added to the
materials in amounts necessary for proper compaction. After compaction,
the course shall be true to grade and cross section, and any depressions
shall be eliminated by the use of additional granular materials, thoroughly
rolled in place. In all cases, the foundation course must be so thoroughly
compacted that it will not weave under the roller and the total depth
after compaction shall not be less than specified.
A.
The developer shall construct a two-course asphalt
cement concrete pavement laid to conform to the required grade, thickness
and cross section shown on the plans. It is the developer's responsibility
to ensure that the road pavement is placed centered in the right-of-way.
If the pavement is not centered, the Highway Superintendent has the
option of requiring that the pavement shall be removed and replaced
centered in the right-of-way.
B.

to Sections 401, 402 and 403 of the current Standard Specifications
of the New York State Department of Transportation.
C.
Before placement or construction of the binder course
of pavement, it is mandatory that all storm and sanitary sewers and
all utilities, including, but not limited to, house connections, water
mains, hydrants, service lines, gas services, telephone, electric
and cable conduits and roof/footing drains shall have been installed
and all fill and backfill shall have been thoroughly compacted to
the satisfaction of the Highway Superintendent. If the binder course
has been placed or constructed and the above-referenced utilities
have not been completely installed, they shall be installed under
the pavement by boring or jacking methods as approved by the Highway
Superintendent or Town Engineer. Open cutting of the binder course
for utility installation shall not be permitted.
D.
The asphalt concrete binder course shall be uniformly
spread by a self-propelled mechanical spreader with mechanical screed
and heating unit and in sufficient depth to provide the required finished
thickness after rolling thoroughly with a ten-ton roller.
E.
After the binder course has been completed, it shall
be thoroughly vacuum cleaned (broom swept is not acceptable) of foreign
material to the satisfaction of the Highway Superintendent. A tack
coat of asphalt emulsion shall be applied to the surface at the rate
of 0.1 to 0.2 gallon per square yard. A final wearing course of fine
asphalt concrete shall be uniformly spread by a self-propelled mechanical
spreader equipped with mechanical screed and heating unit and insufficient
depth to provide the required finished thickness after rolling thoroughly
with a two- or three-wheel tandem roller weighing approximately 10
tons.
F.
Extreme care shall be exercised in the placing of
asphalt concrete to ensure that all longitudinal joints shall be lapped
in the placing of adjoining passes and that all lateral joints are
trimmed before continuing with the placing of additional materials
on that pass.
G.
No paving will be permitted prior to April 1 and after
November 15 of each year, except with the written permission of the
Highway Superintendent. Under no circumstances shall material be placed
when the surface temperature is below 40 °F. or the weather is
inclement.
B.
