Nothing in this chapter shall require any changes in a building
permit, site plan or zoning variance which was approved before the
enactment of this chapter, provided that construction shall have been
started within one year from the effective date of this chapter, and
the project shall be continuously pursued to completion. Otherwise,
said approvals and permits shall be void.
All developments shall be served by paved streets. The arrangement
of streets not shown on the Master Plan or Official Map shall provide
for the appropriate extension of existing streets, conform to the
topography, as far as practical, and allow for continued extension
into adjoining undeveloped tracts with a minimum right-of-way of 50
feet. When a development adjoins land capable of being developed further,
suitable provisions shall be made for future street access.
A. Local streets. Local streets shall be so designed as to discourage
through traffic, unless deemed necessary by the approving authority.
B. Pavement width of streets. The pavement width of all streets shall
be a minimum of 30 feet for all local streets and may be greater for
collector and arterial streets.
C. Minimum right-of-way width.
(1) The right-of-way width shall be measured from lot line to lot line
and shall not be less than shown below, except when shown at a greater
width on the Master Plan or Official Map of the Borough of Westwood,
or when said street constitutes an extension of an existing street
with a width greater than 50 feet:
(a)
Arterial streets: 80 feet.
(b)
Collector streets: 60 feet.
(d)
Marginal access streets: 40 feet.
(2) The right-of-way width for internal roads in developments shall be
determined on an individual basis and shall be of sufficient width
and design to safely accommodate traffic, parking and loading, as
well as emergency services.
D. Substandard street right-of-way and pavement width. In connection
with subdivisions that adjoin or include existing streets that do
not conform to widths as shown on the Master Plan or Official Map,
or the street width requirements of this chapter, the applicant shall
dedicate additional right-of-way or pavement width along either one
or both sides of said road. If the subdivision is along one side only,
1/2 of the required extra width shall be dedicated.
E. Street grades. Grades of arterial and collector streets shall not
exceed 4%. Grades on other streets shall not exceed 10%. Maximum grades
on any streets within 50 feet of an intersection shall be 5%. No street
shall have a minimum grade of less than 1/2%. Road cross sections
(crown) shall range between 2% and 3%.
F. Street intersections. Intersecting street center lines shall be as
nearly at right angles as possible, and in no case shall they be less
than 60° at the point of intersection. The block corners at intersections
shall be rounded at the curbline, with a curve having a radius of
not less than 20 feet. Curblines shall be parallel to the center line.
Approaches to all intersections shall follow a straight line for at
least 100 feet, measured from the curbline of the intersecting streets
to the beginning of the curve. No more than two street center lines
shall meet or intersect at any one point. Collector and/or arterial
streets intersecting another street from opposite sides shall either
be directly opposite each other without offset or shall have a minimum
offset distance of 125 feet between center lines. Street jogs with
center-line offsets of less than 125 feet shall be prohibited.
G. Reverse curve tangents. A tangent at least 100 feet long shall be
introduced between reverse curves on arterial and collector streets.
H. Street line deflection. When connecting street lines deflect from
each other at any one point by more than 10° and not more than
45°, they shall be connected by a curve with a radius of not less
than 100 feet for minor streets and 300 feet for arterial and collector
streets.
I. Change in grade. All changes in grade shall be connected by vertical
curves of sufficient degree of curvature to provide a smooth transition
and proper sight distance.
J. Cul-de-sac streets. Cul-de-sac streets shall not exceed a length
of 600 feet. A turnaround shall be provided at the end of the cul-de-sac,
with a right-of-way radius of not less than 50 feet and a curbline
radius of not less than 40 feet. The center point for the radius shall
be on the center line of the associated street or, if offset, to a
point where the curbline radius becomes a tangent to one of the curblines
of the associated street. If a dead-end street is of a temporary nature,
a similar turnaround shall be provided and provisions made for future
extension of the street and reversion of the excess right-of-way to
the adjoining properties.
K. Streets shall be constructed in accordance with the standard specifications
of the New Jersey Department of Transportation (NJDOT). Pavement section
shall consist of the following:
(1) Arterial and collector streets:
(a)
Dense graded aggregate subbase: six inches compacted thickness.
(b)
Bituminous stabilized base course: six inches compacted thickness.
(c)
FABC surface course: two inches compacted thickness.
(2) Local streets:
(a)
Dense graded aggregate subbase: six inches compacted thickness.
(b)
Bituminous stabilized base course: four inches compacted thickness.
(c)
FABC surface course: two inches compacted thickness.
(3) Where subbase conditions are wet, springy, or of such nature that
surfacing would be inadvisable without first treating the subbase,
these areas shall be excavated to a depth of at least 12 inches below
the proposed subgrade and filled with a suitable subbase material
as determined by the Municipal Engineer. Where required by the Engineer,
a system of porous concrete pipe subsurface drains shall be constructed
beneath the surface of the paving and connected to a suitable drain.
After the subbase material has been properly placed and compacted,
the surfacing material shall be applied.
L. Street names. No new street shall have a name which will duplicate
or so nearly duplicate in spelling or phonetic sound the names of
existing streets in Westwood, Hillsdale, River Vale, Emerson and Township
of Washington. The continuation of an existing street shall have the
same name. The names of new streets must be approved by the approving
authority.
M. Sidewalks. Sidewalks shall be required along both sides of a street
in all nonresidential subdivisions unless waived by the approving
authority. A minimum walkway width of four feet shall be constructed
in accordance with the requirements of the Borough Engineer and in
conformance with this chapter. Within the CBD/SPE District, sidewalks
and streetscape shall comply to the design set forth in the Borough's
Master Plan.
N. Where extra width has been dedicated for widening of existing streets,
lots shall begin at such new line, and all setbacks shall be measured
from such new line.
O. Where the property to be subdivided is next to or includes a railroad
right-of-way, suitable provisions shall be made for such things as
road crossings, screening or buffers, freight access, warning signals,
and signs in recognition of the relationship between the railroad
and the subdivision.
P. Curbing. Curbing shall be required on both sides of all streets within
a subdivision. Belgian (granite) block or concrete curbs shall be
used on all Borough streets according to the following standards:
(1) Construction of all curbs shall conform to NJDOT Standards and Specifications
for Road and Bridge Construction, 1989, Section 605, and supplements
thereto, and shall meet the Borough Engineer's approval. All concrete
to be used shall be Class B, as specified in NJDOT Standards and Specifications,
and supplements thereto.
(2) Granite curbs shall have a ten-inch to twelve-inch vertical height.
(3) Curbs shall be set in a Class C concrete base at least four inches
thick in the front and rear of the granite block and at least six
inches thick below the block. The combined block and concrete base
shall have a minimum vertical dimension of 18 inches.
(4) Curbs shall have a six-inch exposed vertical face above the finished
pavement surface.
(5) Joints shall measure 3/8 inch to 1/2 inch in width.
(6) The curb height at all driveway openings shall be lowered to a point
two inches above the finished pavement.
(7) The curbing shall be designed to provide barrier-free curb ramps
constructed in accordance with the Design Standards for Curb Ramps
for the Physically Handicapped of the New Jersey Department of Transportation.
A lighting plan prepared by a qualified individual shall be
provided with major subdivision applications. Streetlighting standards
of a type and number approved by the approving authority and Municipal
Engineer shall be installed at street intersections and elsewhere
as deemed necessary by the approving authority, with intersections
involving collector and arterial streets receiving priority consideration
for streetlights. The developer shall provide for the installation
of underground service.
Monuments shall be the size and shape required by N.J.S.A. 46:23-9.9
et seq. (the Map Filing Law, as amended), shall be placed in accordance
with said statute and shall be indicated on the final plat.
