N.J. Admin. Code § 19:5-7.4

Current through Register Vol. 56, No. 24, December 18, 2024

Section 19:5-7.4 - Streets layout and design

(a) All lots located in any subdivision shall have direct access to an improved public or private street.

(b) The arrangement, character, extent, width, grade and location of all streets shall conform to the NJMC Master Plan and any applicable redevelopment plan of the District, and shall be considered in their relation to existing and planned streets, topographical conditions, public convenience and safety, and in appropriate relation to the proposed uses of the land to be served. The arrangement of streets in a subdivision shall either:

1. Provide for the continuation or appropriate projection of existing principal streets in surrounding areas; or

2. Conform to a plan approved or adopted by the Commission to meet a particular situation.

(c) Local streets shall be designed to minimize use by through traffic.

(d) If a subdivision abuts or contains an existing or proposed limited access highway or arterial street, the NJMC may require design features to buffer residential properties and separate through and local traffic.

(e) If a subdivision borders or contains a railroad ROW or a limited access highway, the NJMC may require a street approximately parallel to and on each side of such ROW, at a distance suitable for the appropriate use of the intervening land, as for park purposes in residential districts, or for commercial or industrial purposes in other districts. Such distances shall be determined with regard for the requirements of approach grades and future grade separations.

(f) Reserve strips controlling access to streets shall be dedicated to the governmental entity with jurisdiction over such streets.

(g) Street jogs are to be avoided on arterial and collector streets. On local streets with a ROW of 60 feet or less, centerline offsets of less than 150 feet shall be prohibited.

(h) A tangent measuring a minimum of 100 feet in length shall be introduced between reverse curves on arterial and collector streets.

(i) Streets shall be designed to provide for the following minimum horizontal sight distances on all curves, measured within street ROW's from a height of four feet above the proposed pavement surface in the right-hand lane:

1. Local streets: 250 feet;

2. Collector streets: 350 feet; and

3. Arterial streets: 500 feet.

(j) Streets shall be designed to intersect as nearly as possible at right angles, and no street shall intersect any other street at less than 70 degrees.

(k) Street ROW widths shall be as shown in the NJMC Master Plan and any applicable redevelopment plan of the District, and where not shown therein, shall not be less than the widths listed in Table 5-1 below:

Table 5-1
Street ROW Widths
Street Type	ROW
Arterial	100 feet, except that 150 feet of ROW shall be
required within 350 feet from the intersection
of the center line of an arterial street with
any other arterial or collector street
Collector	80 feet
Local, residential areas	50 feet
Local, commercial and	60 feet
industrial areas
Marginal access streets, with	40 feet
two-way traffic

(l) Half streets shall be avoided, except for arterial streets, collector streets where applicable, and where they are essential to the reasonable development of the subdivision in conformity with the other requirements of these regulations; or, where the NJMC finds that it will be practicable to require the dedication of the other half of the street when the adjoining property is subdivided. Whenever a half street is existing and adjacent to a tract to be subdivided, the other half of the street shall be platted within such tract.

(m) Dead-end streets, designed to be so permanently, shall not be longer than seven times the average lot width or 600 feet, whichever is less, and shall have a turn-around at the closed end that has an outside roadway diameter of at least 70 feet and a ROW diameter of at least 100 feet. Curvilinear cul-de-sacs shall be avoided.

(n) No street names shall be used which will duplicate or be confused with the names of existing streets. Street names shall be subject to the approval of the NJMC.

(o) Street grades, wherever feasible, shall not exceed the grades in Table 5-2 below with allowance for reasonable vertical curves:

Table 5-2
Street Grades
Street type	Percent grade
Arterial	3%
Collector	4%
Local	5%
Marginal access streets	5%

(p) No street grade shall be less than one-half of one percent. A greater percentage of grade may be required, however, where necessary to provide adequate drainage.

(q) The following minimum curb radii listed in Table 5-3 below shall be provided at intersections:

Table 5-3
Minimum Curb Radii
Type of Street	Intersecting with	Minimum curb radii
Local Residential	Local Residential	20 feet
Local Residential	Collector	30 feet
Local Residential	Arterial	30 feet
Collector (commercial or	Collector (commercial or	50 feet
industrial) or Arterial	industrial) or Arterial

(r) In addition to the required ROW widths described in this section, a line-of-sight triangle shall be provided and maintained in accordance with N.J.A.C. 19:4-8.5, and the portion of the line-of-sight triangle outside the ROW shall be dedicated as an easement if required by the governmental entity(s) with jurisdiction over the ROW(s).

(s) The subdivider shall conform with local standards for street pavement thickness and width.

(t) The subdivider shall provide appropriate street signage and traffic control devices as may be required by, and in accordance with the requirements of, the NJMC and the governmental entity with jurisdiction over the ROW.

(u) The subdivider shall provide appropriate street lighting as may be required by, and in accordance with the requirements of, the NJMC, the appropriate utility company, and the governmental entity with jurisdiction over the ROW.
