All developments shall be served by paved streets. The arrangement of streets not shown on the Master Plan or Official Map shall provide for the appropriate extension of existing streets, conform to the topography, as far as practical, and allow for continued extension into adjoining undeveloped tracts with a minimum right-of-way of 50 feet. When a development adjoins land capable of being developed further, suitable provisions shall be made for future street access.
A. Local streets. Local streets shall be so designed as to discourage through traffic unless deemed necessary by the approving authority.
B. Pavement width of streets. The pavement width of all streets shall be a minimum of 30 feet for all local streets and may be greater for collector and arterial streets.
C. Minimum right-of-way width. The right-of-way width shall be measured from lot line to lot line and shall not be less than 50 feet in any case, except when shown at a greater width on the Master Plan or Official Map of the Borough of Franklin Lakes or when said street constitutes an extension of an existing street with a greater width than 50 feet.
D. Substandard street right-of-way and pavement width. In connection with subdivisions that adjoin or include existing streets that do not conform to widths as shown on the Master Plan or Official Map, or the street width requirements of this chapter, the applicant shall dedicate additional right-of-way or pavement width along either one or both sides of said road. If the subdivision is along one side only, 1/2 of the required extra width shall be dedicated.
E. Street grades. Grades of arterial and collector streets shall not exceed 6%. Grades on other streets shall not exceed 10%. Maximum grades on any streets within 100 feet of an intersection shall be 3%. No street shall have a grade of less than 1/2%. Road cross sections (crown) shall range between 2% and 3%.
F. Street intersections. Intersecting street center lines shall be as nearly at right angles as possible, and in no case shall they be less than 60º at the point of intersection. The block corners at intersections shall be rounded at the curbline with a curve having a radius of not less than 20 feet. Curblines shall be parallel to the center line. Approaches to all intersections shall follow a straight line for at least 100 feet measured from the curbline of the intersecting streets to the beginning of the curve. No more than two street center lines shall meet or intersect at any one point. Collector and/or arterial streets intersecting another street from opposite sides shall either be directly opposite each other without offset, or shall have at least 250 feet offset distance between center lines. Street jogs with center-line offsets on local streets of less than 125 feet shall be prohibited.
G. Reverse curve tangents. A tangent at least 100 feet long shall be introduced between reverse curves on arterial and collector streets.
H. Street line deflection. When connecting street lines deflect from each other at any one point by more than 10º and not more than 45º, they shall be connected by a curve with a radius of not less than 100 feet, for minor streets, and 300 feet, for arterial and collector streets.
I. Change in grade. All changes in grade shall be connected by vertical curves of sufficient degree of curvature to provide a smooth transition and proper sight distance.
J. Cul-de-sac streets. A turnaround shall be provided at the end of the cul-de-sac with a right-of-way radius of not less than 50 feet and a curbline radius of not less than 40 feet. The center point for the radius shall be on the center line of the associated street, or if offset, to a point where the curbline radius becomes a tangent to one of the curblines of the associated street. If a dead-end street is of a temporary nature, a similar turnaround shall be provided and provisions made for future extension of the street and reversion of the excess right-of-way to the adjoining properties.
K. Streets shall be constructed in accordance with the standard specifications as set forth in the Residential Site Improvement Standards, New Jersey Administrative Code, Title 5, Chapter 21.
L. Street names. No new street shall have a name which will duplicate or so nearly duplicate in spelling or phonetic sound the names of existing streets. The continuation of an existing street shall have the same name. All street names shall be subject to final approval of the Planning Board.
M. Sidewalks. Sidewalks shall be required along both sides of a street in all nonresidential subdivisions, unless waived by the approving authority. A minimum walkway width of four feet shall be constructed in accordance with the requirements of the Borough Engineer and in conformance with this chapter.
N. Where extra width has been dedicated for widening of existing streets, lots shall begin at such new line and all setbacks shall be measured from such new line.
O. Where the property to be subdivided is next to or includes a railroad right-of-way, suitable provisions shall be made for such things as road crossings, screening or buffers, freight access, warning signals, and signs in recognition of the relationship between the railroad and the subdivision.
