The subdivider shall observe the following requirements and principles of land subdivision in the design of each subdivision or portion thereof:
A. 
General. The subdivision plat shall conform to design standards that will encourage good development patterns within the borough. Where either or both an official map or master plan has or have been adopted, the subdivision shall conform to the proposals and conditions shown thereon. The streets, drainage, rights of way, school sites, public parks and playgrounds shown on an officially adopted master plan or official map shall be considered in approval of subdivision plats. Where no master plan or official map exists, streets and drainage rights-of-way shall be shown on the final plat in accordance with Section 20 of Chapter 433 of the Laws of 1953[1] and shall be such as to lend themselves to the harmonious development of the borough and enhance the public welfare in accordance with the following design standards:

A tangent at least one hundred (100) feet long shall be introduced between reverse curves on streets.
(8) 
When connecting street lines deflect from each other at any one (1) point by more than ten degrees (10º), and not more than forty-five degrees (45º), they shall be connected by a curve with a radius of not less than one hundred (100) feet.
(9) 
All changes in grade shall be connected by vertical curves of sufficient radius to provide a smooth transition and proper sight distance.
(10) 
Dead-end streets.
(a) 
Dead-end streets (cul-de-sac) shall not be longer than six hundred (600) feet and shall provide a turnaround at the end with a radius of not less than sixty (60) feet and tangent whenever possible to the right side of the 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 access right-of-way to the adjoining properties.
(11)

In blocks over one thousand (1,000) feet long, pedestrian crosswalks may be required in locations deemed necessary by the Planning Board. Such walkway shall be ten (10) feet wide and be straight from street to street.
(3) 
For commercial, group housing or industrial use, block size shall be sufficient to meet all area and yard requirements for such use.
D. 
Lots.
(1) 
Lot dimensions and area shall not be less than the requirements of Chapter 416, Zoning.
(2) 
Insofar as is practical, side lot lines shall be at right angles to straight streets and radial to curved streets.
(3) 
Each lot must front upon an approved street at least sixty (60) feet in width, except in the case of a minor subdivision as hereinbefore defined.
(4) 
Where extra width has been dedicated for widening of existing streets, lots shall begin at such extra width line, and all setbacks shall be measured from the line.
(5) 
Where there is a question as to the suitability of a lot or lots for their intended use due to factors such as rock formation, flood conditions or similar circumstances, the Planning Board may, after adequate investigation, withhold approval of the lots.
E.

(3) 
Natural features such as streets, brooks, hilltops and views shall be preserved whenever possible in designing any subdivision containing such features.
