[Ord. #585, § 607A; Ord. #1103, § 33]
Streets shall be designed to converge traffic flows at convenient access points. Street design shall discourage through traffic within residential areas. To facilitate traffic flows at major intersections, turning lanes may be required. Acceleration and deceleration lanes shall be installed at exits and entrances to commercial and industrial centers unless the Board is satisfied that such lanes are not required.
The arrangement of streets shall be such as to provide for the extension of existing streets.
No development plan controlling access to streets shall be approved except when the control and disposal of the land controlling access has been placed with the Township or unless a protective deed restriction has been approved by the Board.
All cul-de-sacs shall be no more than 1,000 feet in length and provide access to no more than 40 dwelling units, except in PRD-5 Mt. Laurel Option developments, where cul-de-sacs shall be no more than 1,250 feet in length and provide access to no more than 80 dwelling units.
The approval of any map or plat delineating streets by the governing body of the Township shall in no way be construed as an acceptance of any street indicated thereon.
An applicant for development on a proposed lot fronting on a temporary cul-de-sac shall be required to pay for the cost of improving the road to the end of the lot. The location of the temporary cul-de-sac shall be determined by the Township Engineering department, taking into consideration the eventual development of the remainder of the properties beyond the applicant's lot, costs, environmental constraints and good subdivision design.
[Ord. #585, § 607B; Ord. #1103, § 33]
Topsoil shall be stripped from the proposed road bed for the entire width of pavement, shoulders, gutters, curbs, sidewalks or other required improvements. All unsuitable material shall be removed. The subgrade shall be compacted to a density of not less than 95% under optimum moisture conditions. All embankments shall conform to current New Jersey State Highway Specifications as amended. The subbase shall be prepared under the supervision of a New Jersey Professional Engineer who shall certify, prior to placement of pavement, that the subbase was properly constructed in accordance with this section.
The quality of surfacing and base materials used shall adhere to the minimum standards set forth by the county or State when the street is within their jurisdiction. For streets under the jurisdiction of the Township, the following standards shall apply:
As a minimum, any new street shall be constructed according to the specifications and procedures set forth in the New Jersey State Highway Department Standard Specifications (1961) as amended.
The base course shall be five inches stabilized base placed on four inches of subbase Type 5A, which has been inspected and approved by the Township Engineer.
The surface course for all classes of Township streets shall consist of one and one half (1 1/2) inches of Bituminous Concrete, Type FABC-1, Mix No. 5.
An alternate pavement section may be approved by the Board if the applicant can demonstrate to the Board's satisfaction that the proposed pavement section is adequate to serve the anticipated volume and type of traffic. However, for any pavement section approved, the surface course must be bituminous concrete Type FABC-1, Mix No. 5.
[Ord. #585, § 607D; Ord. #760, § 45]
Pavement width shall be as follows:
Local Public and Private Streets. The Planning Board may approve a reduction in the pavement width of minor streets to 24 feet.
Collector Streets. If the street will not have on-street parking, or residential uses with frontage on the collector, or will not have curbs, the pavement width may be reduced to 26 feet, with a four-foot-wide graded berm (shoulder) area on each side.
[Ord. #585, § 607E; Ord. #760, §§ 46-47]
If granite block, stones shall not be less than 12 inches in height and shall be constructed to show a vertical face above the roadway pavement of six inches.
If concrete, the curbing shall meet the following specifications:
The concrete to be used for curbs shall be Class B concrete as specified in the New Jersey State Highway Specifications for Curbs and Gutters.
Expansion joints shall be provided at maximum intervals of 10 feet and shall be sealed as specified by the Township Engineer.
Openings for driveway access shall be in such widths as shall be recommended by the Township Engineer in accordance with Sections 21-38 and 21-39 of this chapter. The curb at such driveway openings shall be depressed to the extent that 1 1/2 inches extends above the finished pavement. The rear top corner of the curb shall have a radius of 1/4 inch, and the front top corner shall have a radius of 1 1/2 inches.
Concrete curbs for local roads shall be eight inches wide at the base and not less than seven inches wide at the top. Their height shall not be less than 20 inches and shall be constructed to show a vertical face above the pavement of six inches. The rear top corner of the curb shall have a radius of 1/4 inch, and the front top corner shall have a radius of 1 1/2 inches.
Depressed curb ramps for the handicapped shall be installed at all curb radii where sidewalks intersect the curb in accordance with the laws of the State of New Jersey.
[Ord. #585, § 607F; Ord. #1103, § 34]
Sidewalks shall be installed along Township streets in all residential developments except for standard residential development in the R-1, R-2 and R-3 Zones in order to ensure safe pedestrian movement within the development and into adjacent areas. Additionally, in the nonresidential zones, sidewalks shall be installed in all areas wherever pedestrian traffic is anticipated to occur such as between parking areas and buildings or between buildings. Sidewalks shall be four feet wide and constructed of four-inch thick Class B concrete, as specified in the New Jersey State Highway Specifications, as amended, and in accordance with the Township standard details.
The Board may waive or modify the requirements for sidewalks in residential developments if it is demonstrated by the applicant that adequate provisions for pedestrian circulation has been provided through such methods as pedestrian paths, except that sidewalks may still be required along principal routes to schools.
The Board may waive the requirements for concrete in the constriction of sidewalks if the applicant can demonstrate that the substitute construction material(s) will not result in a shorter useful life of the sidewalk or that an increase in maintenance costs will not occur.
Driveway aprons shall be constructed between the curb (or edge of pavement) and the sidewalk or, in the absence of sidewalk, for the distance of 10 feet back from the curb (or edge of pavement). The apron shall be either asphalt or concrete, on recommendation from the Township Engineer. The Township Engineer may also waive or vary apron requirements. Where driveways are on a county or state road, the apron shall be constructed in accordance with requirements of the applicable agency.

All swales shall be designed to carry a twenty-five-year frequency storm for the drainage area served.
Drainage swales shall have a maximum side slope of three to one (3:1).
All swales shall have a minimum grade of five-tenths (0.5%) percent to prevent silting and a maximum slope that will prevent erosion. Paved inverts and/or energy dissipators may be required.
The invert of all swales shall be a minimum of three inches below the pavement section.
All swales shall be hydroseeded or similarly treated to ensure a stable erosion control surface immediately after construction.
The street right-of-way shall be widened to include all drainage swales where Township maintenance of such swales will be required to ensure that the drainage system will function in a manner that protects the pavement from stormwater infiltration.
[Ord. #585, § 607J; Ord. #983, § 1; Ord. #1103, § 35]
A street name shall not conflict with or be mistaken for an existing street name in the municipality or postal zip code unless the street is a logical extension of an existing street.
