Footnotes:
   1.    Must be served with public sewer and public water to qualify for the sizes noted. If public sewer and public water are not available, minimum lot area is 1.0 acre.
   2.    Lots located along the circular portion of a cul-de-sac bulb or outside knuckle of a street corner may be reduced to a minimum of 30 feet, provided the lot width requirement is met and the lot is not capable of being further divided. In addition, lots at the end of an access easement in an infill subdivision need only provide frontage pursuant to those regulations, as found in 11-8-4(A).
   3.    Buildings taller than 2 stories and 30 feet shall be set back from any adjoining residential property in a RR, R-1, R-2, R-2MH, or MHP Zone an additional two feet for each foot in height over 30 feet.
   4.    Park strip option: When the yard of the property abuts an improved street right-of-way with an existing park strip (aka planting strip - an area between the back of the curb and the sidewalk) that is at least 5 feet wide, the minimum yard setback requirement is 10 feet, provided any garage opening shall be not less than 22 feet from the back of the public sidewalk in this situation.
   5.    See definition of "lot line, front" for options on selecting the front yard on corner lots. See also minimum garage entrance setback.
   6.    Placing a structure larger than 120 square feet closer than 5 feet from an adjacent lot triggers fire-resistant construction requirements pursuant to the adopted Building Code. If the structure is not constructed to such fire-resistant standards, the minimum setback requirement is 5 feet.
   7.   No wall or visual screen shall be installed on the portion of the structure that utilizes the reduced setback. Any portion of the structure that meets the minimum setback required for the primary structure to which it is attached may be enclosed with a wall or visual screen.
