shall be a minimum of 2 1/2 inches.
D.
All sidewalks shall be constructed on a base of approved
gravel or crushed stone of at least six inches in depth. Sidewalks shall be
constructed with a transverse slope of 1/4 inch per foot toward the traveled
way, except that the slope may be away from the traveled way if the runoff
will not affect adjacent properties. The longitudinal slope of a sidewalk
shall not exceed 10%.
E.
Where vehicular traffic is anticipated to cross an area
of sidewalk, the following specifications shall apply:
(1)
Cement concrete sidewalks shall be six inches thick and
shall be mixed, reinforced and placed in accordance with the specifications
above.
(2)
Asphalt concrete shall consist of a three-inch binder

with the specifications for streets or highways, except that the specification
for size and type of roller shall not apply.
A.
The developer shall so design, layout and construct all
driveways, both within and without the limits of the rights-of-way, so that

feet of the street or highway right-of-way line.
B.
The developer shall obtain all necessary permits and
construct all driveway entrances to the satisfaction of the appropriate governing
agency. All necessary driveway entrances within the subdivision shall be constructed
at the time of construction of the curbs.
C.
To the extent practicable, all driveway grades shall
be restricted to a maximum of 15%. Any driveway grade in excess of 6% shall
be paved with either blacktop or oil and stone in order to prevent erosion
and resultant sedimentation on the public road network unless it is specifically
certified by the developer's professional engineer through a detailed
drainage/erosion study and plan that such sedimentation will not occur.
A.
The developer shall construct all road intersections
in accordance with Figure 14, except in the case of a new road intersecting

the end of this chapter.
B.
A minimum of 275 feet of unobstructed stop line sight
distance shall be provided for both approaches along the street or highway
at driveway entrances.
C.
Stop line sight distance shall be measured from a point
on the center line of the approaching lane of the minor road or driveway 12
feet behind the projected edge of roadway of the major road to a point on
the center line of the approaching lane of the major road. The height of eye
and height of object shall both be assumed to be 44 inches above the road
pavement. Each approach to the intersection shall be considered separately.
The developer shall furnish and install a four-way road name sign at
every road intersection made by the roads he constructs. Signs and posts shall

shown on Figure 17, Appendix B.[1]
[1]
Editor's Note: Figure 17 of Appendix B is included at the end of this chapter.

of Section 710 of the current standards of the New York State Department of

All signs, signals, markings and other control devices for maintenance
and protection of traffic must conform to the requirements of the New York

and the designated Town Engineer, in writing, these drains may be piped to
the roadway stormwater pipe drain to which they shall be connected on top
only. Such drains must be installed prior to the start to fine grading of
the roadway.
