The following criteria shall be the basis for
the design of all streets and stormwater collection systems.
All highways and streets shall be designed in
accordance with the following minimum standards:
A. Street widths.
(1) On a collector street, the width of the right-of-way
shall be 50 feet, of which 34 feet shall be paved.
(2) On a minor street, the right-of-way shall be 50 feet,
of which 20 feet shall be paved.
(3) On a lane, the right-of-way shall be 30 feet, of which
18 feet shall be paved.
(4) All streets which terminate at the water shall have
a minimum width of 75 feet for a distance not less than 100 feet from
the water.
(5) Culs-de-sac or dead-end streets shall be provided
with a turnaround with a minimum radius of 50 feet. If such street
is constructed so that the turnarounds are left with an island of
natural or replanted vegetation of no less than a diameter of 100
feet enclosed by the standard width of the right-of-way, this island
may be accepted as part of the reserved area requirement.
B. No curve greater than a twenty-degree curve shall
be used for horizontal alignment.
C. Where a street has been constructed so that the elevation
of the street is higher or lower than the elevation of the adjacent
property, a cut or fill easement shall be granted so that a one-on-two
slope may be maintained.
D. Intersections.
(1) All street intersections shall have radius curves
with a minimum tangent distance of 25 feet.
(2) Street intersections, points of curvature and points
of tangency and all angle points shall be monumented. Such monuments
shall be of stone or concrete, at least two feet six inches long and
four inches by four inches square, and so placed that at least four
inches thereof shall appear above ground, except where a concrete
sidewalk grade is already established, the monument shall be set flush
to sidewalk grade.
(3) Four-cornered intersections should be avoided wherever
possible, and the angle of intersection of all streets shall be as
near 90º as feasible.
(4) The intersections of minor streets leading into a
collector street from opposite sides of the collector streets shall
be separated by a minimum distance of 125 feet between center lines.
E. Each map shall show all details and, whenever possible,
the point or points of beginning, or terminals shall be fixed with
relation to a street intersection or a highway monument at an angle
point in a recorded street. If no permanent point is reasonably to
be found, monuments must be definitely placed at least three points
before filing of said map and be shown thereon. Each map shall also
show a center line profile of existing grades and proposed grades
at a scale of horizontal one inch equals 50 feet and vertical one
inch equals 10 feet for each road or street.
[Amended 1-12-2004 by L.L. No. 1-2004]
It is the requirement of the Planning Board
to return stormwater to the ground within subdivisions. This is to
be done through the use of recharge basins and/or leaching basins
and/or lots specifically designated as drainage lots to be used for
no other purpose. All stormwater collection systems shall be designed
in accordance with the following standards and shall be approved by
the Superintendent of Public Works or the Village Engineer.
A. Whenever necessary, drop inlets, leaching basins or
storm sewers shall be placed to intercept drainage runoff. Wherever
determined by the Village Engineer or the Superintendent of Public
Works, provision must be made for right-of-way to a recharge basin
in preference to easement to a river, pond, stream or bay.
B. Such drainage system shall be constructed outside
the street line.
C. Such drainage area or recharge basin shall be enclosed
by a six-foot-high link wire fence to be landscaped according to regulations.
D. When necessary for drainage or for any other reason,
curbs and gutters shall be built of concrete or other approved material.
Detailed plans shall be furnished to the Superintendent of Public
Works. All specifications concerning concrete for structures or other
purposes are to conform to the specifications outlined by the Suffolk
County Department of Public Works.
E. The storage capacity of stormwater recharge basins
shall provide for four inches of rainfall on the tributary area. Where
it is evident that possible overflow of the recharge basin will cause
property damage, the above capacity shall be increased 50%.
F. The maximum depth of a recharge basin shall be 10
feet.
G. All piping laid to such recharge basin or stormwater
collection area shall be shown in detail, both as to grade and construction,
on the map to be submitted to the Superintendent of Public Works.
