Current through Register Vol. 56, No. 21, November 4, 2024

Section 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.
