B. Geometric requirements.
(1) All roads/streets shall be designed following generally accepted
highway engineering principles.
(2) Road/Street jogs with center-line offsets of less than 125 feet shall
be avoided.
(3) In general, all roads/streets shall join each other so that, for
a distance of at least 150 feet, the road/street is approximately
at right angles to the street it joins.
(4) The road/street plan shall bear a logical relationship to the topography
of the property; and if building sites are proposed along said proposed
road/street, the road/street shall be arranged so as to obtain as
many of the building sites as possible at or above the grade of the
roads/streets.
(5) Road/Street grades.
(a)
Grade requirements.
[1]
No road/street grade shall be less than 1/2% or exceed the following,
with due allowances for reasonable vertical curves:
[a] Major traffic streets: 5% (up to 8% for 500 feet).
[b] Collector street: 8% (up to 10% for 500 feet).
[c] Minor street: 12% (up to 15% for 500 feet).
[2]
Roads/Streets shall have a grade not to exceed 3% for a distance
within 50 feet of the road/street right-of-way line of any intersecting
road/street.
(b)
The gradients of roads/streets shall be not less than 0.5% without
curbs and gutters, and 0.3% with curbs and gutters. On roads/streets
where curbs, gutters and sidewalks are not required, there shall be
a berm.
(c)
Minimum vertical and horizontal visibility (measured 4 1/2
feet eye level to tail lights 18 inches above ground level) for curves
shall be as follows:
[1]
Major highways: 500 feet.
[2]
Collector streets: 300 feet.
[4]
Roads/Streets shorter than 500 feet: 150 feet.
(d)
All road/street right-of-way lines at intersections shall be
rounded by curves of at least twenty-foot radius, and curbs, if required,
shall be adjusted accordingly.
(e)
A tangent of at least 100 feet shall be introduced between reversed
curves on all roads/streets.
C. Construction.
(1) General.
(a)
The applicant shall establish and clearly mark the side of the
limits of the right-of-way, and location and elevation of drainage
structures. Such markers shall be maintained at the applicant's
expense until construction of roadway, drainage and shoulder have
been completed and accepted by the Town of Tusten.
(b)
Concrete monuments or other permanent markers shall be installed
every 300 feet on both sides of the right-of-way.
(c)
Unless otherwise directed in writing by the Town Superintendent,
final grading of the right-of-way and construction of road/street
pavement shall be delayed until all utilities, including house connections,
have been installed and backfill in trenches has thoroughly settled.
Earth shoulders and flow lines of ditches shall be maintained at all
times at the applicant's expense during the course of construction.
(d)
Samples of materials to be used in the construction of the roadway
shall be furnished to the Town Superintendent. The applicant shall
be required to pay for any standard engineering tests which the Town
Superintendent shall deem necessary.
(e)
The Town Superintendent shall be granted full access to any
construction taking place under these specifications and shall be
allowed to take any standard engineering field test which may be appropriate.
(f)
All thicknesses called for are compact thicknesses.
(g)
The roadway shall be constructed as shown on the attached typical
section.
(h)
Guide rails shall be installed in accordance with the latest
New York State Department of Transportation requirements.
(i)
All signs installed shall be in conformance with the New York
State Manual of Uniform Control Devices.
(2) Earthwork.
(a)
Clearing and grubbing. Clearing and grubbing shall consist of
clearing the area of all trees, down timber, snags, brush and other
vegetation and shall include grubbing stumps or roots. The area to
be cleared and grubbed shall be limited to that area to be covered
by the roadway proper, shoulders, side slopes and ditches. All cleared
materials shall be removed from the development or burled in a lot
unsuitable for a building or otherwise disposed of in a manner approved
by the Town Board.
(b)
Subbase. All rock and boulders larger than six inches in diameter
shall be excavated six inches below the finished subgrade of the roadway.
All topsoil or otherwise soft or unstable materials shall be removed
from within the roadway, shoulders and ditches and shall be replaced
with suitable borrow. Fill required to complete the approved grades
shall be acceptable to the Town Board.
(3) Road/Street section. Cut and fill slopes in earth shall be not less
than 1 on 2. Subbase, at least 30 feet in width, shall consist of
a bottom course of at least 12 inches of ROB gravel and a top course
of at least six inches of well-graded ROB gravel or washed gravel
with no particles of material larger than two inches in diameter.
The subbase shall be crowned, shaped to a smooth grade and well compacted.
(4) Surfacing.
(a)
Base course shall be 12 inches thick, 30 feet wide and will
consist of either eight inches of shale (shale to be approved by the
Highway Superintendent) with four inches of processed gravel (two-inch-maximum
stones) on top or bank-run gravel with maximum stone size of six inches.
Upon installation of the base, 5/10 of a gallon of MC 30 road oil
per square yard shall be applied. Gravel base with MC 30 coating shall
be allowed to settle for at least one year before pavement is put
on.
(b)
Pavement. Pavement shall be two inches thick (compacted), of sufficient width to meet standards provided in Chapter
241, Subdivision of Land, of the Town Code, and consist of one of the following:
[1]
A penetration pavement consisting of two inches of No. 2 crushed
stone coated with at least one gallon per square yard of MC 3000 road
oil and blotted with No. 1 crushed stone. Surface is to be coated
with 4/10 of a gallon per square yard of MC 3000 road oil and blotted
with sufficient No. 15 crushed stone to prevent bleeding.
[2]
A cold-mix pavement consisting of No. 2 stone mixed with latex
MP emulsion at 13 gallons to 20 gallons per ton (amount varies in
order to provide coating of different type stones) in an approved
motor paver, then blotted with No. 1 stone to fill the voids and sealed
with RS-2 emulsion at 0.4 gallon per square yard, No. 1S stone at
12 pounds per square yard.
[3]
An asphaltic concrete pavement consisting of one two-inch course
of dense binder and sealed with RS-2 emulsion at 0.4 gallon per square
yard and No. 1S or 1A stone at 12 pounds per square yard.
(5) Design and construction of drainage structures.
(a)
All drainage facilities with waterway area of 25 square feet
or less shall be designed to accommodate runoff for a storm of five-year
frequency.
(b)
Drainage structures with a waterway area over 25 square feet
will be designed by a professional engineer and shall be capable of
carrying the runoff from a storm of ten-year frequency.
(c)
In no event shall the diameter of any sluice pipe be less than
15 inches.
(d)
Drainage channels shall be designed following generally accepted
hydraulic engineering principles. Channels shall be normally of trapezoidal
cross-section with side slopes of two feet on one foot.
(e)
The banks on both sides of drainage facilities and bridges servicing
a stream or larger watercourse shall have rip-rapped construction
of the banks beyond the head walls. The amount of rip-rap required
shall be determined by the Town Highway Superintendent.

have names and not numbers or letters. The applicant shall pay for
the cost of approved road/street signs and sign posts.
(8) Utilities.
(a)
Wherever possible, utilities shall be underground and shall
be placed in the road/street right-of-way between the ditches and
outside boundary of the right-of-way to simplify location and repair
of lines when they require attention.
(b)
Whenever it is necessary that utilities cross the roadway, they
shall do so at a right angle to the roadway.
Variations to the standards contained herein may be approved
by the Town Board on the recommendation of the Town Highway Superintendent
