Notes:
   1.   Measured at the setback line; for flag lots, the setback starts at the end of the pole section.
   2.   See section 3.10.08 of this title, regarding development standards.
   3.   See figure 3.3.04 of this chapter to determine minimum setbacks and section 3.3.041 of this chapter regarding snow shedding roof setback. However, no building element shall be closer to a side property line than 1/2 the building element height (see chapter 2, "Definitions", of this title); use the greater of this measurement or that determined from section 3.3.04 and figure 3.3.04 of this chapter.
   4.   If vehicle access is restricted on such street, a setback of 15 feet is permitted.
   5.   Exception to height allowances as noted in chapter 7, "Special Districts", of this title. All buildings over 35 feet in height will require a conditional use permit. Fifty feet (50') maximum height without a conditional use permit when twenty-five percent (25%)  of the floor area of the development is devoted to local housing units as noted in section 3.3.21.
   6.   To points of building elements in opposition.
   7.   Determine rear setback using section 3.3.05 of this chapter.
   8.   For zero lot line developments, the maximum lot coverage standard shall be increased by 10 percent for each lot line with a 0 foot setback. For example, for a lot with 1 zero lot line and a size of 10,000 square feet, the percent of lot coverage would be: 30% + 10% x (30%) = (30+3)% = 33%.
   9.   Maximum square footage of a structure will be determined, as defined by the International Building Code, adopted by reference in title 2 “Building Regulations.” The square footage of all floors, conditioned and unconditioned, and habitable attics, and including covered porches, decks, and other usable areas under roofs as measured to the outside of the exterior walls; excluding eaves unless intended to cover useable space.
