[Amended 5-11-2010 by L.L. No. 7-2010; 6-8-2020 by L.L. No. 3-2020]
The Town shall not accept any property for highway purposes,
until and unless the following specifications have been complied with:
A.
Width. Right-of-way width shall be not less than 50 feet. The graded
roadbed shall be 30 feet wide, consisting of a pavement of at least
20 feet in width, and shoulders, exclusive of ditches, of at least
five feet in width. Ditches shall have a front slope of one on three,
two feet deep with a two-foot bottom. The back slope shall be one
on two. The roadway shall be cleared of all trees and brush for the
full width of the right-of-way.
B.
Line and grade. The line and grade shall be constructed so as to
maintain a minimum sight distance of 300 feet. Grades shall be no
less than 0.50% or more than 10% without Town approval.
C.
Pavement subbase.
(1)
The type of subbase required for each use shall be as follows: The
source of the material shall be one approved for use by the New York
State Department of Transportation. Material supplied for use as subbase
shall have 100% passing the two-inch sieve, 30% to 65% passing the
1/4 inch sieve, 5% to 40% passing the No. 40 sieve and 0% to 10% passing
the No. 200 sieve.
(2)
If imported material is required for the subgrade, the source and
a random composite sample shall be provided to and reviewed by the
Town prior to being brought to the site. Imported material shall have
100% passing the six-inch sieve for fill up to one foot of subgrade
and 100% passing the two-inch sieve for fills within one foot of subgrade.
The imported material shall have no more than 40% passing the No.
40 sieve and 15% passing the No. 200 sieve.
(3)
All final subgrade under proposed pavement shall be proof rolled
for identifying of soft areas with a ten-ton roller or a loaded ten-wheel
dump truck. Soft areas shall be scarified. Dried, and recompacted
prior to fill being placed. Retest by proof roll as necessary. As
an option the contractor can remove soft areas and replace with suitable
material and retest by proof roll.
(4)
Prior to placing subbase two to five gallon pails of the proposed
subbase material shall be provided to the Town for gradation and proctor
testing.
(5)
Subbase shall be placed in lifts not to exceed 12 inches and compacted
to the requirements stated in the soils report. If not stated, the
compaction requirement shall be 95% of maximum dry density per ASTM
D1557 (modified proctor).
(6)
Final grading of subbase shall be to ±one inch of that designated
on the drawings and ±one inch of the required thickness for
thickness of eight inches or greater and ±1/2 inch for thickness
less than eight inches.
D.
Drainage. The road shall be constructed with adequate ditches, culverts
and other structures to provide suitable drainage under all conditions.
Culverts shall be at least 12 inches in diameter and installed with
a grade of at least 1%.
E.
Paving. Pavement of the two ten-foot wide lanes shall consist of
three inches NYSDOT Type 1 Asphalt Base Course (if applicable), 2 1/2
inches NYSDOT Type 3 Binder Course, 1 1/2 inches NYSDOT Type
7 Top Course.
F.
Concrete sidewalk.
(1)
The width of the concrete sidewalk will vary and be approved by the
Town. The depth of the concrete and subbase will be determined by
the approved width in accordance with the concrete walk detail indicated
on the typical roadway cross section detail.[1] The concrete mix design is to achieve a minimum 4,500
psi compressive strength within 28 days. The gravel subbase is to
meet the requirements of the pavement subbase above. The subgrade
shall be compacted to 95% of the maximum density as determined by
modified proctor ASTM D1557. Expansion joints, control joints and
nominal cross slope to be as indicated below:
(a)
Expansion joint spacing: 20 feet maximum in runs of walks, 30
feet maximum where walks abut concrete curbs, structures or other
fixed objects.
(b)
Control joint spacing: five feet O.C. (U.N.O.).
(c)
Nominal cross slope: 1/8 inch minimum to 1/4 inch maximum per
foot.

Editor's Note: Said detail is included as an attachment to this chapter.
(2)
Sidewalks required to be accessible must meet all applicable accessibility
guidelines.
The proposed design, methods of construction
and type of materials to be used shall be subject to the approval
of the Town Superintendent of Highways before construction as well
as after the work is completed.
In addition to the requirements set forth in §§ 257-11 through 257-13 hereof, the grantor of the property for highway purposes, shall at his own cost, provide the Town with a title policy issued by a title company duly licensed in the State of New York, insuring the Town in a minimum amount as set from time to time by resolution by the Town Board and all of the necessary documents, including the deed conveying the property, shall be subject to the approval of the Town Attorney.
