Notes:
   A   For any wedge-shaped lot the required frontage shall be measured at the building line.
   B   Front yard setbacks measured from street right-of-way.
   C   For buildings of more than one story, the minimum width of the side yard on all lots shall be not less than 10 feet. On a lot where the principal use is a nonresidential building there shall be a side yard of not less than one-half the height of the building but in no case less than 15 feet.
   D   If 25% or more of the lots on one side of the street between two intersection streets are improved with buildings all of which have observed an average setback line less than 35 feet, and no building varies more than 5 feet from this average setback, then a building may be erected on the average setback line so established by the existing buildings.
   E   A building or structure may exceed the maximum height regulations by adding one foot onto the required front, side and rear yards for each two feet of additional height.
   F   Townhomes, as described in the International Residential Code currently adopted by the city, shall be classified R-3 and require no side setback limitations when abutting other townhome R-3 property. When adjacent to other property, there shall be a five foot side setback. For interior lots minimum width shall be 28 feet. End lots must also meet setback requirements of an extra five feet or 15 feet depending on the configuration and adjacent roadways. Minimum total lot area shall be 3,200 square feet.
