In order to provide for streets of suitable location, width and improvement to accommodate prospective traffic and afford satisfactory access to police, fire-fighting, snow removal, sanitation and street maintenance equipment, and to coordinate streets so as to compose a convenient system and avoid undue hardships to adjoining properties, the following design standards for streets are hereby required. (Street classification may be indicated on the Master Plan or Official Map, if any; otherwise, it shall be determined by the Planning Board.)
A. All street pavement, shoulders, drainage improvements and structures, curbs, turnarounds and sidewalks shall conform to all construction standards and specifications as set forth in this chapter or as required by the Planning Board in the subdivision process. Such improvements shall be incorporated into the construction plans required to be submitted by the developer for plan approval.
B. After sewer and water utilities have been installed by the developer, the applicant shall construct curbs and gutters and shall surface or cause to be surfaced roadways to the widths prescribed in this chapter.
C. Adequate provision shall be made for culverts, drains and bridges.
D. Developments that adjoin or contain existing township or county streets that do not conform to widths as shown on the adopted Township or County Master Plan or Official Map (if any) or the standards set forth in this §
149-42 shall have dedicated additional width along either one or both sides of said street. If the development is along one side only, 1/2 of the required extra width shall be dedicated.
E. Minimum street right-of-way and cartway width shall be as shown on the Township Master Plan or Official Map (if any) or, if not shown thereon, shall be as set forth below. The right-of-way width shall be measured from lot line to lot line and shall not be less than the following, provided that no street of a width greater than 50 feet within the right-of-way lines shall be required unless said street constitutes an extension of an existing street of the greater width or already has been shown on the Master Plan at the greater width or already has been shown in greater width on the Official Map.

L. Shade trees shall be installed on both sides of all local streets subject to approval of the Planning Board, at a minimum spacing along each side of the street of 30 feet on center and maximum of 100 feet on center. Varieties shall be approved by the Planning Board. The method of installation and location shall be approved by the Municipal Engineer. Shade trees shall be installed at a minimum size of two-inch caliper. Suggested varieties of trees to be planted within 10 feet of streets or sidewalks are as follows: American white ash, Sentry ginkgo (male grafted only), sweetgum, Amur cork tree, Oriental plane tree, Northern red oak, scarlet oak, pin oak, silver linden, European linden, sugar maple and Norway maple. No trees shall be planted within 30 feet of the cartway on arterial streets.
M. To provide visual continuity, only one variety of shade tree shall be installed on the street. A mixture of varieties of street trees on a street may be installed upon approval of the Planning Board.
N. Bridges of primary benefit to the developer, as determined by the Planning Board, shall be constructed at the full expense of the developer without reimbursement from the township. The sharing expense for the construction of bridges not of primary benefit to the developer as determined by the Planning Board will be fixed by special agreement between the Township Committee and the developer. Said cost shall be charged to the developer pro rata as the percentage of his land developed and so served. In the absence of such an agreement the provisions of Article
VII of this chapter shall apply.
O. Railroad rights-of-way and limited access highways where so located as to affect the subdivision or development of adjoining lands shall be treated as follows:
(1) In residential districts, a buffer strip at least 25 feet in depth, in addition to the normal depth of the lot required in the district, shall be provided adjacent to the railroad right-of-way or limited access highway. This strip shall be part of the development and shall be designated on the plan: "This strip is reserved for screening. The placement of a structure hereon is prohibited."
(2) In districts zoned for business, commercial or industrial uses, the nearest street extending parallel or approximately parallel to the railroad shall, wherever practicable, be at a sufficient distance therefrom to ensure suitable depth for commercial or industrial sites.
(3) Streets parallel to the railroad when intersecting a street which crosses the railroad at grade shall, to the extent practicable, be at a distance of at least 150 feet from the railroad right-of-way. Such distance shall be determined with due consideration of the minimum distance required for future separation of grades by means of appropriate approach gradients and may be required to be at a distance in excess of 150 feet.
