The purpose of this article is to provide the
minimum requirements and material standards for the design and construction
of roads and pavements and the necessary grading standards for new
construction within any public right-of-way or easement.
A.
All road infrastructure and pavements shall be constructed in strict accordance with the approved plans. The construction layout for all phases of the road infrastructure and pavement shall be the responsibility of the developer. The Town will provide inspection of the construction of the road pavement. Cut sheets and grade reference will be provided by the developer to the Town during all phases of the construction. The developer shall provide as-built drawings for the completed construction as specified in § 135-25 of these specifications.
B.
Width, location and construction. Streets shall be
of sufficient width, suitably located and adequately constructed to
conform with the Master Plan and to accommodate the prospective traffic
and afford access for fire fighting, snow removal and other road maintenance
equipment. The arrangement of streets shall be such as to cause no
undue hardship to adjoining properties and shall be coordinated so
as to compose a convenient system.
C.
Arrangement. The arrangement of streets in the subdivision
shall provide for the continuation of principal streets of adjoining
subdivisions, and for proper projection of proposed streets into adjoining
properties which are not yet subdivided, in order to facilitate the
orderly movement of traffic and the extension of needed utilities
and public services such as sewers, water and drainage facilities.
Street extensions shall be constructed in accordance with Town specifications.
Where, in the opinion of the Planning Board, topographic or other
conditions make the continuation of existing streets undesirable or
impracticable, the above conditions may be modified.
D.
Minor streets. Minor streets shall be so laid out
in a way that discourages their use by through traffic.
E.
Frontage on major streets.
(1)
When a subdivision abuts or contains an existing or
proposed major arterial street, the Planning Board may require marginal
access streets, reverse frontage with screen planting contained in
a nonaccess reservation along the rear property line, deep lots with
rear service alleys or such other treatment as may be necessary for
adequate protection of residential properties and to afford separation
of through and local traffic.
(2)
To avoid landlocking developable areas, the contiguous
development (both existing and planned) of frontages along major streets
shall not exceed a distance of 2,000 feet before a street right-of-way
is provided for access to any developable land behind such frontages.
F.
Provision for future resubdivision. Where a tract
is subdivided into lots substantially larger than the minimum size
required in the zoning district in which a subdivision is located,
the Planning Board may require that streets and lots be laid out so
as to permit future resubdivision in accordance with the requirements
contained in these regulations.
G.
Dead-end streets. The creation of dead-end or loop
residential streets will be permitted wherever the Board finds that
such type of development will not interfere with normal traffic circulation
in the area. In the case of dead-end streets, where needed or desirable,
the Planning Board may require the reservation of a twenty-foot-wide
easement to provide for continuation of pedestrian traffic and utilities
to the next street.
H.
Block size. Blocks Generally shall not be less than
400 feet nor more than 1,200 feet in length. In general, no block
width shall be less than twice the normal lot depth. In blocks exceeding
800 feet in length, the Planning Board may require the reservation
of a twenty-foot-wide easement through the block to provide for the
crossing of underground utilities and pedestrian traffic where needed
or desirable and may further specify, at its discretion, that a four-foot-wide
paved foot path be included.
I.
Intersections with collector or major arterial roads.
Minor or secondary street openings into such roads shall be a minimum
of 500 feet apart.
J.
Street jogs. Street jogs with center line offsets
of less than 125 feet shall be avoided.
K.
Angle of intersection. In general, all streets shall
join each other so that, for a length of at least 100 feet from the
point at which the streets join, each street is approximately at an
angle of 90° to the street it joins.
L.
Relation to topography. The street plan of a proposed
subdivision shall bear a logical relationship to the topography of
the property, and all streets shall be arranged so as to obtain as
many of the building sites as possible at or above the grade of the
streets. Grades of streets shall conform as closely as possible to
the original topography. To preserve tree life, street grades in wooded
areas shall be low enough so as not to require additional fill.
M.
Other required streets. Where a subdivision borders
on or contains a railroad right-of-way or limited access highway right-of-way,
the Planning Board may require a street approximately parallel to
and on each side of such right-of-way, at a distance suitable for
the appropriate use of the intervening land (as for park purposes
in residential districts or for commercial or industrial purposes
in appropriate districts). Such distances shall also be determined
with due regard for the requirements of approach grades and future
grade separations.
A.
Widths of rights-of-way pavements. When not indicated
on the Master Plan or Official Map, the classification of streets
shall be determined by the Planning Board. Streets shall have the
following widths:
|
Arterial
|
Collectors and Minor Streets
(feet)
|
Outside Radius of Cul-de-sac
(feet)
|
Marginal Access

B.
Improvements. Streets shall be graded and improved with pavements, sidewalks, storm drainage facilities, water mains, sewers, signs, streetlighting, street trees and fire hydrants, except that the Planning Board may waive, subject to appropriate conditions, such improvements as it considers may be omitted without jeopardy to the public health, safety and general welfare. Notwithstanding the foregoing, the Planning Board may not waive any stormwater drainage facilities that are provided for in a stormwater pollution prevention plan (SWPPP) approved by the Town, unless such SWPPP is revised accordingly and the revised SWPPP is approved by the Town as provided in § 245-61 of the Town Code. Pedestrian easements shall be improved as required by the Town Engineer. Such grading and improvements shall be approved, as to the design and specifications, by the Town Engineer.
[Amended 12-11-2007 by L.L. No. 3-2007]

be in conformance with the lighting system of the Town. Such lighting
standards and fixtures shall be installed after approval by the appropriate
energy company and authorized Town Inspector.
C.
Utilities in streets. The Planning Board shall, wherever
possible, require that underground utilities be placed in the street
right-of-way between the paved roadway and street line to simplify
location and repair of lines. The subdivider shall install underground
service connections to the property line of each lot within the subdivision
for such required utilities before the street is paved.
D.
Utility easements. Where topography is such as to
make impractical the inclusion of utilities within the street rights-of-way,
perpetual unobstructed easements at least 20 feet in width shall be
otherwise provided with satisfactory access to the street. Wherever
possible, easements shall be continuous from block to block and shall
present as few irregularities as possible. Such easements shall be
cleared and graded where required.
E.
Grades. Grades of all streets shall conform in general
to the terrain and shall not be less than 1/2 nor more than 6% for
major or collector streets or 10% for minor streets in residential
zones, but in no case more than 3% within 50 feet of any intersection.
F.
Changes in grade. All changes in grade shall be connected
by vertical curves of such length and radius as meet with the approval
of the Town Engineer so that clear visibility shall be provided for
a safe distance.
G.
Curve radii at street intersections. All street right-of-way
lines at intersections shall be rounded by curves of at least twenty-foot
feet radius and curbs (if required) shall be adjusted accordingly.
H.
Steep grades and curves; visibility of intersections.
A combination of steep grades and curves must be avoided. In order
to provide visibility for traffic safety, that portion of any comer
lot, whether at an intersection entirely within the subdivision or
the intersection of a new street with an existing street, which is
shown shaded on Sketch A,[1] shall be cleared of all growth (except isolated trees)
and obstructions above the level three feet higher than the center
line of the street. If directed, the shaded ground shall be excavated
to achieve visibility.
[1]
Editor's Note: Sketch A is on file in the
Town offices.
I.
Dead-end streets (culs-de-sac). Where dead-end streets
are designed to be so permanently, they should, in general, not exceed
500 feet in length and shall terminate in a circular turnaround having
a minimum outside right-of-way radius of 75 feet and a pavement radius
of 56 feet. At the end of temporary dead-end streets, a temporary
turnaround shall be provided in accordance with Town Standard Specifications.
J.
Watercourses.
(1)
Where a watercourse separates a proposed street from
abutting property, provision shall be made for access to all lots
by means of culverts or other structures of design approved by the
Town Engineer.
(2)
Where a subdivision is traversed by a watercourse,
drainageway, channel or stream, there shall be provided a stormwater
easement or drainage right-of-way as required by the Town Engineer.
In no case shall this easement or right-of-way be less than 20 feet
in width.
K.
Curve radii. In general, street lines within a block,
deflecting from each other at any one point by more than 10°,
shall be connected with a curve, the radius of which for the centerline
of the street shall not be less than 400 feet on major streets, 200
feet on collector streets and 100 feet on minor streets.
L.
Service streets or loading space in commercial development.
Paved rear service streets of not less than 20 feet in width, or in
lieu thereof, adequate off-street loading space, suitably surfaced,
shall be provided in connection with lots designed for commercial
use.
M.
Free flow of vehicular traffic in abutting commercial
developments. In front of areas zoned and designed for commercial
use, or where a change of zoning to a zone which permits commercial
use is contemplated, the street width shall be increased by such amount
on each side as may be deemed necessary by the Planning Board to assure
the free flow of through traffic without interference by parked or
parking vehicles and to provide adequate and safe parking space for
such commercial or business district.
A.
Type of name. All street names shown on a preliminary
plat or subdivision plat shall be approved by the Planning Board.
In general, streets shall have names and not numbers or letters.
B.
Names to be substantially different. Proposed street
names shall be substantially different so as not to be confused in
sound or spelling with present names, except that streets that join
or are in alignment with streets of an abutting or neighboring property
shall bear the same name. Generally, no street should change direction
by more than 90° for a distance of over 1/2 mile without a change
in street name.
A.
