2. The side lot line does not abut an alley and no portion of the building within the side yard exceeds a height of fourteen feet (14') or intersects a plane commencing seven feet (7') in height, measured at the side lot line, and extending at a slope of two horizontal to one vertical (2:1) toward the interior of the site area.

E. Central R-1 Permit: Notwithstanding any other provision of this section, for those lots located south of Olympic Boulevard and west of Roxbury Drive, the planning commission may modify the height limitation set forth in subsection B of this section, the limitations set forth in subsections C1 and C2 of this section, and the limitations set forth in subsections D1 and D2 of this section by a Central R-1 permit issued pursuant to article 24.5 of this chapter provided the rear lot line of the subject lot abuts an alley and provided further that the elevation of the subject lot slopes downhill from the front (street) lot line of the property to the rear (alley) lot line with a minimum difference in elevation of at least twenty feet (20') between the street and the alley. In addition to the findings required by section 10-3-2453 of this chapter, the planning commission shall not issue a Central R-1 permit to allow an accessory structure to exceed fourteen feet (14') in height unless the planning commission additionally finds that the proposed accessory structure will not have a substantial adverse impact on adjacent properties or the public welfare. In making this determination, the planning commission may look at such factors as the impact of the accessory structure on the scale and massing as viewed from adjacent properties, the impact of the accessory structure on available light in neighboring yards, and the cumulative impact to adjacent properties from the proposed accessory structure in combination with existing accessory structures in the vicinity. Under no circumstances shall the height of an accessory structure be permitted to exceed the following:
1. Twelve feet (12') as measured from the lowest finished elevation along the perimeter of the primary structure; and
2. Twenty five feet (25') for a flat roof and thirty feet (30') for a sloped roof with a twenty two foot (22') plate height as measured from the lowest (alley side) existing grade. (Ord. 02-O-2403, eff. 9-3-2002; amd. Ord. 03-O-2431, eff. 11-21-2003)
