Any portion of a lot that was used to calculate compliance with the standards and regulations of this Chapter shall not be subsequently subdivided or segregated from such lot.

L. Measurement of setbacks

N. Setbacks—Livestock buildings and manure storage areas

1. Side Yard Setback. The side yard setback is the setback between a structure and any lot line to which neither the street nor rear yard setback applies. The side yard setback is measured from a side yard lot line to a line parallel to and measured perpendicularly from the side yard lot line at the depth prescribed for each zone. Four-sided corner lots abutting streets on two sides shall have two side setbacks and no rear setback. 2. Front Yard Setback. The front yard setback is measured between a structure and the front yard lot line. The front yard setback is measured from a front yard lot line to a line parallel to (offset to) and measured perpendicularly from the front yard lot line at the depth prescribed for each zone. In lots adjoining two or more front yards, including corner lots, the minimum front yard setback shall apply to all such front yards. 3. Rear Yard Setback. The rear yard setback is the setback measurement between a structure and the rear yard lot line. Four-sided lots adjoining more than one street shall have no rear yard setback. In triangular lots with one street frontage, the rear setback shall be measured from the shorter of the lot lines not adjoining the streey.

1. The minimum setback for any building used to house, confine or feed swine shall be 90 feet. If a greater dimension is specified within this code the greater dimension shall apply. 2. The minimum setback for any building used to house, confine or feed any other livestock shall be 25 feet. If a greater dimension is specified within this code the greater dimension shall apply. 3. The minimum setback for any manure storage area shall be 35 feet. If a greater dimension is specified within this code the greater dimension shall apply.

O. Setbacks—Modifications

The following setback modifications are permitted:

1. When the common property line of two lots is covered by a building(s), the setbacks required by this chapter shall not apply along the common property line; and 2. When a lot is located between lots having nonconforming front yard setbacks, the required front yard setback for such lot may be the average of the two nonconforming setbacks or 60 percent of the required front yard setback, whichever results in the greater front yard setback.
