greater than or equal to the following formula: SSB = (2.5 X SPH) + (N divided by 2) - 95 Where: SSB = Solar setback (the shortest horizontal distance between the shade point and the plane of the northern lot line). SPH = Shade point height (Reduce this dimension by 3 feet if the shade point is a ridgeline between 45 degrees east or west of true than north.) N = North -south lot dimension. Maximum allowable "N" for purposes of calculating the solar setback shall be 90 feet. The following table, which accurately applies the formula, can be used to determine compliance with the solar setback standard.

See Shade Point Height definition in EC 9.0500 and Figure 9.2795. (3) Exemptions to Solar Setback Requirements. A building is exempt from the solar setback standards when any of the following conditions exist: (a) Slopes. The lot on which the building is located has an average slope of 20 percent or more in a direction greater than 45 degrees east or west of true south. (b) ExistinShade. The building will shade an area that is already shaded by Ordinance - 118
