FILE #17-3925 May 15, 2017 Page 2 of 4 To address the issue, it appears that some adjustment of the setback is necessary. This can occur in several ways: Option 1. Create a new zoning district for these neighborhoods, establishing unique lot sizes, widths, and setbacks. A new zoning district should be introduced cautiously, as the opportunity for unintended consequences is higher; many sections of the code unrelated to lot size and width speak specifically to a particular zoning district. Staff does not recommend establishing new zoning districts at this time. Option 2. Amend the size, width, and setback requirements for existing zoning districts. This would apply to all lots within that zoning district, and could conceivable yield additional density through lots splits. Option 3. Amend yard setbacks in selected districts based on the lot size or width. In developing a proposed ordinance, staff examined 36 different lots chosen at random in 'hot spot' neighborhoods throughout the city. The area and lot width were noted, and the side yard setbacks were calculated, either through the survey (accurate) or by measuring from an aerial photo (not as accurate). This information is summarized in the attached Exhibit C, setback comparison. Of the 36 lots, 23 exhibited non -conforming setbacks on at least one side, and of these, 9 had non -conforming setbacks on both sides. Of the 32 non -conforming setbacks, 19 had setbacks less than 10 feet. Staff is supporting an amendment that prescribes side yard setbacks for non -conforming lots due to width as a function of the lot width, proposed to be measured at the applicable lot width: Lot width means the horizontal distance between side lot lines measured at the following locations: (1) For lots which do not abut a lake or tributary, at the rear of the required front yard, measured parallel to the front lot line. (2) For lots which abut a lake or tributary, at the shoreline measured in a straight line between the points at which the side lot lines intersect the OHWL, and at the required structure setback from the OHWL, measured in a straight line between the points of intersection of the side lot lines with the structure setback line.
