New Jersey Administrative Code › Title 5 - COMMUNITY AFFAIRS › Chapter 21 - RESIDENTIAL SITE IMPROVEMENT STANDARDS › Subchapter 4 - STREETS AND PARKING › Section 5:21-4.2 - Cartway width

Current through Register Vol. 56, No. 14, July 15, 2024
(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.
