Note: Intersections of streets shall be at angles as close to
90° as possible, and in no case shall two streets intersect at
an angle smaller than 60°. To this end, where one street approaches
another between 60° and 90°, the former street should be curved
approaching the intersection.

Hot bituminous pavement conforming to the standards set herein
shall be used on all streets within the Town or village centers and
on all arterial roadways. Hot bituminous pavement also shall be used
on heavily trafficked streets, through streets and where deemed necessary
by the Planning Board. Liquid asphalt may be used in more rural areas
where the traffic volume is low and where through traffic is minimal.
The final determination of the paving shall be made by the Planning
Board.
