shoulders on each side, measured between the faces of the ditches.
D. Cul-de-sac streets:
(1) Minimum pavement width: 34 feet.
(2) Minimum radius from center of turnaround to outside edge of pavement:
40 feet.
E. Grading and center-line gradients: per plans and profiles approved

The following specifications shall constitute minimum standards
for the construction and improvement of streets:
A. As nearly as possible, all roadbeds shall be constructed in the center
of the premises being offered for dedication.
B. All streets shall be rough graded the full width of the street in
accordance with the typical street cross section included with these
regulations.
C. The base of all major/minor roadbeds shall be a minimum of 34 feet
in width, and the base of all rural roadbeds shall be a minimum of
34 feet, and both shall have a base of run-of-bank gravel at least
12 inches in depth, with an additional six inches of New York State
Department of Transportation Specifications, Item 4, gravel on top.
A greater depth shall be required if, in the opinion of the Town Superintendent
of Highways, a thicker roadbed is deemed necessary. The base of all
streets shall be constructed in accordance with New York State Department
of Transportation Specifications, Item 3, Subbase Course, Granular
Material, with the following modification: 25% of the material shall
be retained on a one-inch-square screen, and not more than 7% by weight
shall pass a two-hundred-mesh sieve. The base course shall be placed
in maximum six-inch compacted layers. Before any gravel source can
be approved for street construction, representative samples of gravel
must be tested by an approved testing laboratory. A copy of New York
State Department of Transportation Specifications, Item 3, Subbase
Course, Granular Material, as amended above, is appended to this chapter
for reference.
D. Top courses.
(1) The subbase, installed as in Subsection
C above, shall sit and settle at least one winter until the first day of May following installation.
(2) Prior to the installation of the top surface courses, the subbase
shall be reshaped and reformed in accordance with the construction
plans and specifications and the requirements of this chapter.
(3) Prior to the installation of the top surface courses, a prime coat
of oil shall be installed on the subbase.
(4) The base top surface course shall consist of an asphalt concrete
New York State Department of Transportation Specifications, Type 3,
binder plant mix to be installed to a compacted depth of two inches,
or a cold mix consisting of 60% No. 2 stone and 40% No. 1 stone mixed
with 12 gallons per ton of CMS2 installed to a compacted depth of
three inches.
(5) The final top surface course shall consist of New York State Department
of Transportation Specifications, Type 7, 7F top plant mix, to be

square inch. Concrete shall be air entrained with a minimum air entrainment
of 4 1/2% and a maximum air entrainment of 7%.
F. For rural roads, open ditches and driveway culverts with end sections of not less than 20 feet in length may be substituted in place of concrete curbs and gutters. All plans for open ditches and driveway culverts must be prepared by a professional engineer.
