(A) In order to promote the conservation of energy through the use of both passive and active solar systems, streets in residential subdivisions should, where possible, have an east-west alignment. Lots intended for detached dwelling should be of sufficient width to allow the structure to be built with its longest axis running east-west.
(B) In order to allow the orientation of structures on the site so as to maximize potential solar gain, side lot lines should run as near to north-south as possible, providing that the angle between the side of the lot line and the street right-of-way line on a straight street or the tangent to a curved street shall not be less than 80 degrees.
