A. Setback Standard A. This setback is designed to ensure that shadows are no greater than six feet at the north property line. Buildings on lots which are classified as standard A, pursuant to subsection 18.4.8.020.A.1, shall be set back from the northern lot line according to the following formula.

SSB = (H - 6') / (0.445 + S)

Where:

SSB = the minimum distance in feet that the tallest shadow producing point which creates the longest shadow onto the northerly property must be set back from the northern property line. See definition of northern property line in part 18.6.

H = the height in feet of the highest shade producing point of the structure which casts the longest shadow beyond the northern property line. See definition of highest shade producing point in part 18.6.

S = the slope of the lot, as defined in this chapter.

B. Setback Standard B. This setback is designed to ensure that shadows are no greater than 16 feet at the north property line.

SSB = (H - 16') / (0.445 + S)

C. Setback Standard C. This setback is designed to ensure that shadows are no greater than 21 feet at the north property line.
