This is an article regulating the dedication of any road or
drainage facilities in connection therewith in the Town of Delaware,
Sullivan County, New York. It may be referred to as the "Town of Delaware
Road Law."
This article is enacted for the purpose of insuring that all
roads dedicated to the Town of Delaware meet certain minimum standards
of construction and safety. It is further the objective of this article
to avoid the assumption of Town responsibility for roads which would
be difficult and costly to maintain or potential safety hazards until
such deficiencies are first corrected.
This article shall apply to all roads proposed for dedication
to the Town of Delaware, Sullivan County, New York. No road shall
be accepted for maintenance by the Town of Delaware unless said road
meets the standards contained herein and has been reviewed and approved
by the Town of Delaware Highway Superintendent.
The following shall be the minimum requirements for any road
dedication to the Town:
A. Right-of-way. A legal right-of-way of not less than 50 feet shall
be provided. "Legal right-of-way" shall mean the width dedicated to
road purposes, which may be greater than the area actually used as
a traveled portion, shoulders and drainage facilities. Greater widths
may be required to include the top of cuts or bottom of fills.
B. Line and grade. The line and grade of all roadways shall be constructed
or reconstructed to maintain a minimum sight distance in either direction
of 300 feet measured at eye level. Grades shall be no less than 0.5%
nor more than 12.0%, except that grades of up to 15% may be accepted
for distances of 500 feet separated by distances of 500 feet. Horizontal
curves shall have a minimum radius of 510 feet and a maximum curvature
of 11.5°.
C. Road section. The road section shall, as a minimum, meet the standards
utilized in the "Typical Road Cross Section - Town of Delaware," which
is attached and hereby made part of this article. This includes minimum widths for the traveled portion
of the road and shoulders of 20 feet and five feet, respectively.
"Traveled portion" shall mean that part of the road with base and
top constructed as herein provided and over which vehicles may be
driven. Cut and fill slopes shall be no greater than one on two or
50% using earth and three on one in rock. The road base shall be a
minimum of 30 feet in width.
D. Road surface. Each road shall contain a subbase of material placed
on a stable and compacted subgrade or ground of which no rock particle
shall exceed two feet in diameter. The use of underdrains and geotextile
filter or stabilization fabrics may be directed by the Town Highway
Superintendent to insure a stabilized subgrade. A bottom course of
the subbase shall be required in every instance and shall consist
of a thirty-foot-wide, eight-inch course of bank run gravel or crushed
stone, of which no particle shall exceed such a size as will pass
through a four-inch-square hole or sieve. This shall be topped with
a twenty-foot-wide, four-inch course of selected gravel or crushed
stone, of which no particle shall exceed such size as will pass through
a two-inch-square hole or sieve. Each course will be installed in
lifts not exceeding six inches in depth and will be compacted with
a vibratory compactor achieving a compaction satisfactory to the Town
Highway Superintendent. Shoulder material will be the same as the
subbase top course. A bituminous surface shall be installed and shall
be a minimum of 30 feet in width to include the shoulders. The bituminous
surface shall have a compacted thickness of at least three inches,
consisting of a two-inch course of Type 3 binder hot-mix asphalt concrete
and a one-inch course of Type 6F top hot-mix asphalt concrete or a
three-inch course of sealed cold-mix asphalt.
E. Drainage.
(1) At each point where the road is intersected by a driveway which requires
that surface drainage water be carried under the drive, a sluice pipe
of not less than 12 inches in diameter nor less than 20 feet in length,
constructed of corrugated or heavy steel pipe, heavy-duty polyethylene
(HDPE), or equivalent, as approved by the Town Highway Superintendent,
shall be installed across the width of the driveway and extending
an additional one foot beyond on both sides. It shall be installed
with a minimum of one foot of tamped impermeable cover. In instances
involving unusually heavy traffic, the Town Highway Superintendent
may also specify greater dimensions for driveway culverts and sluices.
Headwalls shall be installed on each end of the pipe.
(2) At each point along the road where a cross drain is required, a sluice pipe of not less than 15 inches in diameter nor less than 40 feet in length, constructed of corrugated or heavy steel pipe, heavy-duty polyethylene (HDPE), or equivalent, as approved by the Town Highway Superintendent, shall be installed across the width of the base and extending two feet beyond on both sides. It shall be installed with a minimum of two feet of tamped impermeable cover consisting of one foot of compacted earth and one foot of gravel or crushed stone, as specified in §
180-10D above. In instances involving unusually heavy traffic or large drainage basins, the Town Highway Superintendent may consult with the Sullivan County Soil and Water Conservation District and/or specify greater dimensions for culverts and sluices. Headwalls shall be installed on each end of the pipe. Any watercourse requiring a drainage structure which will have a waterway area in excess of 150 square feet in size or a span across the watercourse of 15 feet shall be designed by a professional engineer. Any headwalls, drop inlets, catch basins, manholes or similar structures for the removal of stormwater shall be of a design and material approved by the Town Highway Superintendent.
F. Dead-end streets. Dead-end streets shall end in a cul-de-sac with
a surface area of not less than 80 feet in diameter and a right-of-way
of not less than 120 feet in diameter. Within the center of this cul-de-sac
and surfaced area an unsurfaced area of not more than 40 feet in diameter
may be permitted with approved internal drainage. No structures may,
however, be permitted in this area.
G. Guardrails. Guardrails of a type approved by the Town Highway Superintendent
shall be installed in any instance where the difference in elevation
from the edge of a shoulder to the toe of any slope within the road
right-of-way is greater than six feet. Should the right-of-way be
in excess of 50 feet in width, guardrails will be required in any
instance where the slope away from the road exceeds 35%.
H. Miscellaneous. All slopes shall be seeded and mulched to prevent
erosion. All signs installed shall be in conformance with the New
York State Manual of Uniform Traffic Control Devices. If name signs
are provided they shall comply with standards established by the Town
Highway Superintendent, and no road shall be named the same as any
other existing or proposed highway within the Town of Delaware. Intersections
shall be as close to 90° as possible but in no case less than
60°. Intersections shall be offset a minimum of 125 feet. All
road curves shall be adequately banked.
I. State requirements. All other requirements of state law, insofar
as Town highway construction is concerned, also apply to roads proposed
for dedication to the Town of Delaware. These requirements are in
addition to any specifications outlined herein.
Variations to the standards contained herein may be approved
by the Town Board upon recommendation of the Town Highway Superintendent
in order to accommodate unusual or severe topographic conditions.
No approved variations, however, shall constitute a change in the
basic specifications set forth as applied to other roads.
This article shall supersede all prior local laws, ordinances,
rules and regulations relative to the standards for roads and highways
proposed for dedication to the Town of Delaware, and they shall be,
upon the effective date of this article, null and void.
