This law shall be known and cited as the "Town of Inlet Minimum
Road Design and Construction Standards."
The standards and procedures contained herein are intended to
insure that;
A.
All standards in this section are minimum requirements. The Planning
Board may require additional design standards or vary these standards
in any particular case, based upon the recommendation of the Town
Highway Superintendent or Town Engineer.

** At all points along a road, there shall be an unobstructed
line of sight in each direction for the minimum distance specified.

C.
Relation to terrain. All roads shall be logically related to the
existing topography, soils, vegetation, and other natural features
and shall be coordinated into a logical and efficient system. Areas
with steep slopes, shallow soils, soils with a water table at or near
the surface, and soils that are highly susceptible to erosion or slippage
shall be avoided insofar as practical. Roads shall be designed to
be parallel to natural land contours where possible. Long stretches
of road straight downhill should be avoided in order to minimize erosion
problems, and for safety reasons. All roads shall be arranged so as
to obtain a maximum number of building sites at or above the grade
of the roads. Road layout shall minimize stream crossings and shall
avoid traversing slopes exceeding 12%.
D.
Intersections. Roads shall intersect one another at right angles.
No proposed intersection with an existing road shall be less than
125 feet from any existing intersection unless the proposed intersection
is directly opposite the existing intersection so as to create a four-way
intersection.
E.
Dead-end roads. Dead-end roads shall be provided at the closed end
with a circular turnaround having a minimum radius of at least 135
feet.
F.
Access to adjoining property. In order to make possible the extension
of roads or utilities into neighboring properties, the arrangement
of roads in a subdivision shall provide for connection to adjoining
lands, which may be subdivided in the future.
G.
Names and numbers. Names of new roads shall not duplicate existing
or platted roads. New roads which are extended or in alignment with
existing roads shall bear the name of the existing roads.
H.
Road signs. The subdivider shall provide and erect road signs of
a type to be approved by the Town Board at all road intersections
prior to acceptance of the constructed roads.
I.
Utilities. Installations of utility distribution and service lines
shall be planned at the time road layout is determined.
A.
All standards in this section are minimum requirements and must be
designed by a New York State licensed professional engineer. The Planning
Board may require additional construction standards in any particular
case based upon the recommendation of the Town Highway Superintendent
or Town Engineer. Also, the Planning Board may waive or vary the requirements
of this section upon the recommendation of the Town Highway Superintendent
or Town Engineer.
B.
All improvements shall be made at the expense of the subdivider.
C.
All rights-of-way shall be clear of trees and shrubs.
D.
All areas to be filled for road construction shall be cleared and
grubbed prior to placement of fill. Clearing and grubbing shall consist
of removal of all woody vegetation, including trees, fallen trees,
logs, stumps, roots, and brush. All fills shall be compacted to provide
stability of material and to prevent undue settling.
E.
All roadbeds shall consist of an approved geotextile stabilization
fabric extending the entire length of the roadbed, with a minimum
width of at least 17 feet, centered on the roadbed, for roadbeds of
twenty-foot width. Wider roadbeds, culs-de-sac, parking areas and
any other surfaces that will be supporting vehicular traffic will
require wider coverage of geotextile stabilization fabric as determined
by the Town Superintendent of Highways.
F.
All roadbeds and areas specified in Subsection E shall have a minimum of 12 inches of approved base course over the geotextile stabilization fabric. Base course is to be daylighted to all ditches (i.e., full width of roadbed) and shall be adequately compacted.
G.
All roadbeds and areas as specified in Subsection E shall be topcoated over the base course with a minimum of three inches of driveway mix, properly compacted.
H.
All road surfaces shall have a final crown slope of 3/4 inch to one
inch per foot.
I.
Bottom of ditches shall be a minimum of 24 inches below the top of
the roadway crown. All ditching requirements shall be determined and
specified by the Superintendent of Highways.
J.
Culverts shall be no less than 12 inches in diameter and have a smooth
bore. The pitch for all culverts shall be 1/4 inch to 1/2 inch per
foot. Placement of culverts and areas requiring larger diameter culverts
to contain runoff may be required by the Superintendent of Highways.
K.
Periodic inspections to determine conformity for construction standards
are required and will be coordinated by the Superintendent of Highways.
L.
Driveway entrance requirements, guide rails, safety signage, lighting
and roadbed alignment at intersections with existing roads shall be
determined by the Superintendent of Highways.
M.
Paving of any roadways by the Town of Inlet after dedication to the
Town shall be at the discretion of the Town Board and Superintendent
of Highways.
N.
All necessary drainage facilities to manage stormwater runoff created
by any new street or road or by redevelopment within the subdivision,
including grading, whether located within the street or road right-of-way
or elsewhere, shall be installed prior to takeover and/or final plat
approval.
O.
Final determination for acceptance of all roads to be turned over
to the Town of Inlet shall be jointly made by the Superintendent of
Highways and the Town Board.
