The arrangement of streets not shown on the Master Plan or Official Map shall be such as to provide for the appropriate extension of existing streets.
Minor streets shall be so designed as to discourage through traffic.
The right-of-way width shall be measured from lot line to lot line and shall not be less than the following:
A. 
Arterial streets: 80 feet.
B. 
Collector streets: 60 feet.
C. 
Minor streets: 50 feet.
D. 
Marginal access streets: 40 feet.
E. 
The right-of-way width for internal roads and alleys in multifamily, commercial and industrial development shall be determined on an individual basis by the Planning Board, and shall in all cases be of sufficient width and design to safely accommodate the maximum traffic, parking and loading needs and maximum access for fire-fighting equipment and shall be designed and located in accordance with the requirements of the City Engineer.
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 shall dedicate additional width along either one or both sides of the road. If the subdivision is along one side only, 1/2 of the required extra width shall be dedicated.
Street intersections shall be as nearly at right angles as is possible and in no case shall be less than 60°. The block corners at intersections shall be rounded at the curbline, with a curve having a radius of not less than 20 feet. Also, only one point of access and one point of egress may be allowed each property except where large frontages are present. In those latter cases, the City Engineer shall advise the Planning Board as to the safety requirements involved.
Corner clearances shall be maintained within that area bounded by the lines of the intersecting street and a diagonal joining the points on each street line distant 20 feet from the point of intersection or, in the case of a rounded corner, at the point of tangency. Within this area, no structure, wall, embankment, terrace, porch, piazza, fence, hedge, vegetation or other obstruction, other than shade trees trimmed to a distance of at least 10 feet above the curbline, shall be permitted above a height of two feet above the horizontal plane through the curbline.
Unless necessary to provide access to a lot in separate ownership existing before the date of this chapter, no driveway access to property or additional street intersection may be permitted within sight triangles as specified herein.
Street jogs with center-line offsets of less than 125 feet shall be prohibited.
A tangent at least 100 feet long shall be introduced between reverse curves on arterial and collector streets.
When connecting street lines deflect from each other at any one point by more than 10° and not more than 45°, 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.
Dead-end streets (culs-de-sac) shall not be longer than 600 feet and shall provide a turnaround at the end with a radius of not less than 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 excess right-of-way to the adjoining properties.
No street shall have a name which will duplicate as to be confused with the names of existing streets. The continuation of an existing street shall have the same name.
Street pavement width for new streets shall include the distance between curblines and for residential streets shall be at least 36 feet in width. Street pavement width for urban business and primary streets shall be as recommended by the City Engineer.
No subdivision showing reserve strips controlling access to streets shall be approved except where the control and disposal of land comprising such strips has been placed in the City Council under conditions approved by the Planning Board.
No street shall have a minimum grade of less than 0.5%.
