B.

Special provisions for lot coverage on substandard lots. Lot coverage may be determined by using the following formula: (A/B) * C = D (%)

A = lot area required by the applicable district

B = lot area of existing lot

C = percentage of lot coverage allowed by the applicable district

D = percentage of lot coverage allowed for the substandard lot.

In no case shall the lot coverage exceed fifty percent, unless otherwise allowed by this title.

C.

Special front and rear yard setbacks on substandard lots. Either the front or rear yard setback may be determined by using the following formula: (A/B) * C = D

A = depth of the existing lot

B = lot depth required by the applicable district

C = front or rear yard setback required by the applicable district

D = front or rear yard setback allowed for the substandard lot

In no case shall the front or rear yard setback be less than ten feet or twenty feet to a garage, either attached or detached, unless otherwise allowed by this title.

D.

Side yard setbacks for substandard lots. Side yard setbacks may be determined by using the following formula: A = (A/B) * C = D

A = width of the existing lot

B = lot width required by the applicable district

C = side yard setback required by the applicable district

D = side yard setback allowed for the substandard lot

In no case shall the interior side yard setback be less than three feet for all portions of the structure, including those noted in Section 18.46.030(A), nor shall a flanking street side yard setback be less than ten feet.
