N.J. Admin. Code § 5:21-4.2 - Cartway width
(a) Cartway width for each street classification
shall be determined by parking and curbing requirements that are based on the
intensity of development served by that street.
(b) Intensity of development shall be based on the
number of dwelling units per gross acre of land served by a particular street,
excluding the acreage of dedicated common open space or other areas restricted from
future development, as follows:
Intensity |
Dwelling Units per Gross Acre |
Low |
Less than or equal to 4 |
Medium |
More than 4 and less than or equal to 8 |
High |
More than 8 |
(c)
Cartway widths for each street classification are as shown in Table 4.3
below.
(d) Cartway width also shall
consider possible limitations imposed by sight distances, climate, terrain, and
maintenance needs.
(e) Municipalities
may require additional cartway width for major or minor collectors which are part of
a designated bike route as indicated in the bicycle circulation part of the
municipal master plan to make them consistent with the AASHTO guidelines for
bicycle-compatible streets.
NOTES:
a See Table 4.2 for
definitions of street hierarchy and N.J.A.C. 5:21-4.2for definitions of low, medium,
and high intensity of development.
b
Parking lane refers to parallel parking, except in the case of residential access
streets with nonparallel parking, which have perpendicular parking.
c The 30 foot cartway would accommodate two seven
foot parking lanes and a 16 foot traveled way.
d 20 foot minor collector cartways are permitted only when there is no
direct driveway access to or from the street in question.
e Cartway widths of cul-de-sac stems should
conform to the applicable street type. Right-of- ways for cul-de-sac stems shall
extend a minimum of eight feet beyond the cartway. Cul-de-sacs shall provide for a
cartway turning radius of 40 feet and a right-of-way line eight feet beyond the edge
of the cartway. No agreement to exceed the turning radius specified shall be
executed pursuant to
N.J.A.C.
5:21-3.6for purposes of emergency vehicle access
unless supporting documentation prepared by the planning or zoning board of
adjustment engineer is submitted demonstrating that the specific emergency vehicle
in question cannot negotiate this turn.
f Cartway and right - of- way widths of marginal
access streets and right - of- way requirements should conform to standards of
either residential access or minor collector streets, as dictated by average daily
traffic. If the classification is a minor collector requiring a 36 foot cartway,
cartway width may be reduced to 28 feet, since frontage is restricted to one side of
the street.
g Cartway widths of divided
streets should conform to standards of street classification, as dictated by
anticipated average daily traffic, and be applied as aggregate dimensions of two
street segments. Divided streets shall be provided with cut-throughs at a maximum of
1,200 foot intervals.
h See
N.J.A.C.
5:21-4.3(c) for additional
requirements.
i Right -of-way width
applies only to streets proposed for dedication as shown on approved
plans.
j See
N.J.A.C.
5:21-4.5(b) for additional
requirements.
k Rural streets and rural
lanes are permitted only within developments which do not exceed an average daily
traffic count of 500 and 200, respectively.
l Municipalities may require additional width for
major or minor collectors which are part of a designated bicycle route as indicated
in the circulation part of the municipal master plan to make them consistent with
the AASHTO guidelines for bicycle-compatible streets.
m Cartway widths of multifamily cul- de- sac stems
should conform to the applicable residential access street type. Cul-de-sacs shall
provide for a cartway turning radius of 40 feet or other suitable means for vehicles
to turn around, such as hammerheads. Where not located on private property, a
right-of-way line eight feet beyond the edge of the cartway shall be provided. No
agreement to exceed the turning radius specified shall be executed pursuant to
N.J.A.C.
5:21-3.6for purposes of emergency vehicle access
unless supporting documentation prepared by the planning or zoning board of
adjustment engineer is submitted demonstrating that the specific emergency vehicle
in question cannot negotiate this turn.
n Sidewalks provided for streets with nonparallel
parking shall be placed in accordance with
N.J.A.C.
5:21-4.5(e).
o. Cartway and right -of-way widths for
multifamily courts shall comply with the design criteria for residential access
streets, based on the parking configuration. Multifamily courts need not be provided
with a means of turning around; however, their length shall not exceed 300 feet.
p There is no ADT limit for multifamily
courts; however, the length of a multifamily court is limited to 300
feet.
