14. Setback Plane Height Restrictions.
(a) In addition to the general height restrictions in Subsection 3-111A of this Code, all buildings on any lot within the R-A, R-B, or R-C Districts shall be subject to, and comply with, the setback plane height restrictions herein set forth.
(b) Except as provided in subparagraph (c) or (d) no portion of a building on any lot shall intercept the planes that begin at points 8 feet directly above grade at the side lot lines and run at 45 degree angles toward the interior of such lot until they reach the maximum building height permitted on the lot.
(c) For lots having a lot width of 80 feet or less, no portion of a building on any such lot [except as provided in subparagraph (d) below] shall intercept any plane that begins at points directly above grade at a side lot line at a height determined by the following formula:
Height (in feet) of beginning points for setback plane = 8 + [0.15 (80 - W)]
where "W" is the lot width of the lot in question, and runs at a 45 degree angle toward the interior of such lot until it reaches the maximum building height permitted on the lot.
(d) The following structures and architectural features shall be permitted to extend into and through the setback plane, but only to the extent set forth below:
