until the following terms and conditions have been met, without cost
or expense to the Town:
(1)
The highway right-of-way and construction plans shall be prepared
by a professional engineer and shall include a survey of lands to
be conveyed prepared by a professional land surveyor. Both professionals
shall be licensed to practice in New York State.
(2)
The highway right-of-way shall be approved by the Town Highway Superintendent
and the Town Engineer. All highway rights-of-way shall be four rods
in width.
(3)
On all dead-end highways, a turnaround shall be provided as required by the Town highway construction standards set forth in § 114-3 et seq. Dedication of right-of-way or easement shall be provided as applicable.
(4)
A drainage report containing calculations and proposed culverts,
ditches and other drainage structures or facilities shall be submitted
for review and approval of the Highway Superintendent and Town Engineer.
B.
All rights-of-way dedicated to the Town of Somerset shall be without
cost to the Town. The Town, in its sole discretion and as a condition
of acceptance of said dedication, may require the construction of
the base and pavement to be done by the Town Highway Superintendent
or by an approved independent contractor pursuant to the provisions
of the Town Law, and the entire expense thereof shall be paid solely
by the applicants.
C.
The Town Board reserves the right to accept or reject offers of dedication
in its sole discretion.
A.
No construction work of any drainage facilities or pavement shall
be started without a construction permit. Said permit will not be
issued until a subdivision map or a road dedication map has been approved
by the Town Board. No subdivision map or road dedication map shall
be offered to the Town Board for its approval until plans and specification
for the necessary improvements have been submitted to and reviewed
by the Highway Superintendent and the Town Engineer.
B.
Application for the construction permit for drainage facilities and
pavements with appurtenances shall be made to the Town of Somerset
Highway Superintendent. For highways connecting to state and/or county
highways, approval by the respective agency shall be indicated. Each
construction permit application shall be accompanied by two complete
sets of previously approved design plans and specifications. The applicant
must also submit a time schedule for the work to be completed in accordance
with the requirements of these standards.
C.
Permits will be issued upon payment of a fee to be established by
the Town Board. All construction work which is done without the required
permit and which is in conflict with the requirements of the Town
Board or is not in conformance with approved plans and specifications
shall be removed or changed to meet these requirements at the expense
of the applicant.
A.
The rights-of-way for highway purposes shall have a minimum width
of 66 feet for their entire length and shall intersect at an angle
of not less than 75°. There shall be no dead-end roads with turnarounds
unless a reserve of sixty-six-foot-wide right-of-way is provided for
the future extension of a Town highway to an adjacent property.
B.
Culs-de-sac are discouraged, but if needed for approved site development,
shall conform to the minimum standards contained herein. Offsets,
irregularities and short curves in the right-of-way limits can be
sufficient cause for the Town Board to refuse issuance of a construction
permit.
The Town Board will accept only those rights-of-way which contain
all the necessary roads, shoulders or gutters, storm sewers and appurtenant
structures which have been constructed in accordance with the specifications.
The rights-of-way located in areas served by a sanitary sewer system
and/or water distribution system must contain the facilities constructed
in accordance with all permitting authorities.
The applicant shall be held responsible for all phases of the
construction work shown on the application for the construction permits
and shall be required to protect all adjoining property, existing
highway facilities and utilities. The applicant shall be required
to repair or replace any such properties or facilities damaged or
destroyed by him or his employees through the construction operations.

and any special conditions of the permit for construction shall be
in accordance with the following procedure:
(1)
Any person receiving a permit for construction under these standards
shall be required to pay for the services of an observer appointed
by the Town during the installation of the improvements and shall,
before commencing the work, furnish a bond or cash deposit in an amount
to be determined by the Town Board to insure payment of such observer.
(2)
The applicant shall be required to notify the Highway Superintendent
in writing before commencing with the work. The Superintendent and
the designated observer shall be notified by the applicant no less
than 24 hours before the commencement of work and shall keep the observer
advised as to the work installation schedule in order that the work
may be properly and fully observed at all stages of the installation.
Any construction work that is done without the required observation
shall be subject to verification of compliance, and the expense for
this shall be borne by the applicant.
B.
Upon satisfactory completion of the work, the applicant will be issued
a certificate at completion by the appropriate Town Superintendent.
A.
Clearing, except as otherwise specified, includes the removal or
destruction of all fences, trees, roots, stumps, hushes, timbers and
decayed or growing organic matter above and below the surface of the
ground within the limits of the work in the right-of-way to the extent
shown on the drawings or as determined by the Superintendent.
B.
The applicant shall use every precaution to prevent injury to buildings,
roads, curbs, pipes or poles, trees and shrubs and utilities. He shall
repair or replace any damage done due to negligence on his part. Materials
removed, unless otherwise specified, shall become the property of
the applicant and shall be removed from the job site.
C.
Excavation shall consist of the loosening, loading, depositing rough
and fine grading and the compacting of all materials of every name
and nature, wet or dry, necessary for the preparation of subgrades
or roads, forming ditches, trenches and pits for structures, to grade
the site to the elevation shown on the drawings or as required to
make embankments and fills for obtaining material from borrow pits,
other than borrowed topsoil or for any other operation necessary to
complete the work of the contract.
A.
All road grades shall be established in a manner to provide maximum
safety. The minimum acceptable grade is six inches per 100 feet or
0.5%, and the maximum acceptable grade is 10 feet per 100 feet or
10%.
B.
All changes in grade shall be accomplished by vertical curves, and
the maximum change in grade shall not exceed 10%. All vertical curves
shall be separated by a minimum of 50 feet of tangent grade. The minimum
length of vertical curve for the changes in grade is shown in the
following table:

C.
Where topography is such as to create severe hardships, the Highway
Superintendent may grant variations to these requirements.
A.
Proper drainage on new roadbeds shall be provided as shown on the
typical section. Provisions shall be made to have all tiles and storm
sewers drain to a natural drainage area. Where it becomes necessary
to transfer drainage from one side of the road to the other, proper
crossovers of N-12 high-density polyethylene (HDPE) smooth interior,
corrugated galvanized iron or concrete pipe shall be used, subject
to the approval of the Highway Superintendent.
B.
Minimum size of culvert pipe is to be 12 inches in diameter. All
pipe shall be designed to support an H-20 loading. Corrugated galvanized
iron pipe shall be coated inside and outside; arch pipe shall have
a paved invert. Culvert pipe crossing the road pavement shall have
12 inches minimum cover from the road subbase. Culverts crossing driveways
shall have 12 inches minimum cover.
C.
On crossovers, precaution should be used not to overload natural
drainage ditches with an excessive amount of drainage. Headwalls and/or
end sections shall be constructed to Town specifications on all drainage
lines within the right-of-way to prevent erosion and washouts of fill
around drainage pipes.
D.
Catch basins, gutters, underdrains and preformed end sections shall
be as shown on drawings. When unsatisfactory conditions exist and
extra drainage is required, it shall be provided by the applicant
when directed by the Highway Superintendent.
E.
When roadside ditches are deemed acceptable, they shall have a minimum
grade of 0.33%. Ditches shall be located within the right-of-way,
unless otherwise approved to be located in an easement area. Storm
sewers shall be provided in areas that proper shoulder width and ditch
slopes cannot be maintained due to ditch depths.
A.
Subgrades for roadways shall be accurately shaped and crowned to
the grades and levels shown on the drawings or as directed. In the
process of preparing subgrades for roadways, all topsoil must be removed
on both present grade levels and where fill is required to raise the
present grade levels.
B.
If fill is required, it is to be applied in not more than eight-inch
layers and rolled before additional fill is added. Fill for subgrades
for pavement shall be compacted with an approved self-propelled roller
weighing not less than 10 tons. Subgrades shall be rolled only during
the time of optimum moisture content and to the satisfaction of the
Highway Superintendent.
C.
In cases where soft clay, quicksand, muck, wet spots or other unsuitable
material is encountered in the subgrade, it shall be removed to the
limits designated by the Highway Superintendent and properly drained
with six-inch perforated pipe weeps to the storm drainage system and
then refined with dry material or granular materials as directed by
the Highway Superintendent and then properly compacted to maximum
density and bearing capacity. Granular material shall be ROC stone,
as acceptable to the Highway Superintendent.
D.
The subgrade material shall be spread in such depths that the thickness
of any layer, after compaction, shall have a maximum of eight inches.
Water shall be added in such amounts as the Highway Superintendent
may consider necessary to secure satisfactory compaction.
E.
When the moisture content of the layer is within the limits for proper
compaction, the entire surface shall be rolled with a pneumatic-tired
roller having an operating weight of between 1,000 and 2,500 pounds
per tire or a smooth-wheel roller having a minimum weight of 10 tons.
Each portion of the layer shall be covered by a minimum of eight passes
of the roller.
F.
For heavier and more efficient types of rolling equipment, the minimum
number of passes required on all portions of the layer shall be determined
by the Highway Superintendent after appropriate field tests to evaluate
the efficiency of the equipment. In limited areas where the use of
a roller is impractical, approved mechanical tampers shall be used
to compact the material.
G.
After compaction, the course shall be true to grade and cross section.
Any depressions that develop during rolling shall be filled with additional
granular material and further rolled until the entire surface of the
subgrade is true to grade and cross section. Should subgrade become
churned up into or mixed with the granular material through any cause
whatsoever, the applicant shall, at his own expense, remove such mixture
of soil and granular material and replace with additional granular
material.
A.
Minimum drainage requirements shall consist of four-inch perforated
pipe in stone or approved equal for underdrains at each edge of pavement
with underdrain relief, not more than 400 feet to the storm drainage
system, as shown on the Highway Standard Detail. Where extraordinary
conditions exist, additional drainage provisions, as directed by the
Highway Superintendent, shall be provided.
B.
All waterlines, storm sewer and sanitary sewers shall be installed
prior to the work or preparing the subbase and the pavement drainage.
Where waterlines, storm sewers and sanitary sewers are to cross the
roadway, such crossings shall be made before the placement of any
pavement material.
C.
Trenches for these utility crossings in the pavement and gutter or
shoulder areas shall be backfilled with No. 2 run-of-crusher stone
or slag from the elevation of the initial bedding of the utility to
the elevation of the subgrade. These crossings of the pavement areas
shall be reviewed by the Highway Superintendent or his designated
representative before the commencing of paving operations.
D.
All storm sewer pipe, catch basins, manholes, grating, etc., will
be provided as shown on the construction standard detail drawings.
After the subgrade has been prepared, the filter fabric shall
be installed as shown on the highway cross-section detail and in accordance
with New York State Department of Transportation (NYSDOT) standards.
If gutters are required after the subgrade has been prepared,
the filter fabric placed, and the proper drainage provided and the
Highway Superintendent has reviewed the work for compliance with the
plans, the first six-inch bottom course may be placed and compacted
for the total width of the pavement, or not less than four feet in
width centered over the drain tile. The contractor shall then place
the forms and construct the standard gutters. After the forms are
pulled, the outside voids shall be backfilled before the second course
is spread and compacted.
A.
After the subgrade has been prepared, the filter fabric placed and
the proper drainage and gutters, if required, have been provided and
the Highway Superintendent has reviewed the work for compliance with
the plans, a course of approved run-of-crusher stone shall be evenly
spread with spreader equipment to an even thickness so when rolled
it will produce two courses with a compacted thickness of not less
than six inches for each course.
B.
The roller shall be an approved self-propelled type weighing not
less than 10 tons. Rolling of each course shall begin at the sides
and continue toward the center of the road. Rolling shall be repeated
until the stone particles are thoroughly keyed in place and until
there is no movement or weaving of the course ahead of the roller.
C.
It is imperative that the second course conform accurately to the
line and grade specified and shown on the plans. If the subgrade material
shall become churned up into or mixed with the bottom course through
any reason whatsoever, the applicant shall, at his own expense, remove
such mixture of subgrade material and crushed stone or slag and replace
with new crushed stone or slag placed in accordance with the procedure
outlined above.
D.
After proper compaction has been attained for each course and inspected
and approved by the Highway Superintendent, the surface of each course
shall then be immediately filled (chinked) with Clean No. 1 broken
stone, after which it shall be compacted with a self-propelled roller
weighing not less than 10 tons.
E.
After compaction, the top surface of these courses shall not extend
above the theoretical grade elevation for these courses.
A.
After the bottom courses are properly prepared, the contractor shall
install the bituminous plant mix surface pavement, as per Section
401 of the New York State Department of Transportation Specifications.
B.
The surface pavement shall consist of four inches followed with a
top course of 403.16 with a compacted thickness of two inches. A ten-ton
self-propelled, steel-wheeled roller or an approved equal shall be
used to compact these surface courses.
C.
The surface shall be tested with a sixteen-foot straight edge or
string line placed parallel to the center line of the highway or on
any portion of the highway surface. Variations exceeding 1/4 inch
shall be satisfactorily eliminated or the pavement relaid at the expense
of the applicant.
The Town Highway Superintendent may vary or modify any of the
requirements herein which he determines to be in the best interest
of the Town of Somerset.
