Streets shall be laid out so as to provide, with existing or proposed streets, free circulation for vehicles, with access to lots so far as possible from heavy traffic.
(4) 
If adjoining property is not subdivided but is, in the opinion of the Board, suitable for ultimate development, provision may be required for proper projection of streets into such property by continuing appropriate streets within the subdivision to the exterior boundary thereof.
(5) 
Reserve strips prohibiting access to streets or adjoining property shall not be permitted, except where, in the opinion of the Board, such strips shall be in the public interest.
(6) 
Street jogs with center line offsets of less than 125 feet should be avoided.
(7) 
The minimum center line radii of curved streets shall be 275 feet for principal streets and 100 feet for minor streets.

Streets shall be laid out so as to intersect as nearly as possible at right angles. No street shall intersect any other street at less than 60°.
(9) 
Street lines at all intersections shall be rounded with a curve at each corner having a radius of not less than 25 feet. However, when the intersection of two streets varies more than 10° from a right angle, the radius of the curve at the acute angle may be less and at the obtuse angle may be greater than 25 feet to the extent approved or required by the Board.
(10) 
There shall be provided at least two recognized means of access for each subdivision, except one comprising only one dead-end street.
