The purpose of this article is to establish base density, intensity, and dimensional requirements for each standard zoning district.

(Ord. No. 16-07, 6-20-2016)

A.

Except where otherwise expressly stated, all lots and improvements within the rural, open space and residential standard zoning districts shall comply with the regulations prescribed in figures V(1) and V(2), and all lots and improvements within nonresidential standard zoning districts shall comply with the regulations prescribed in figures V(5) and V(6). ^[12]

B.

Allowable yard setback adjustments, intrusions into required yards, and exceptions to maximum height are found in sections 520-31 through 520-33. Substandard lots, nonconforming uses, nonconforming structures, and nonconforming sites legally created before establishment of these requirements are addressed in article XIV.

(Ord. No. 16-07, 6-20-2016)

A.

Limitations on yard setback adjustments.

(1)

No yard shall be reduced in area or dimension so as to make such yard less than the minimum required by this chapter. If an existing yard is less than the minimum required, it shall not be reduced further, except where exempted by the provisions of this section.

(2)

No required yard or lot area allocated to satisfy the minimum yard or lot area requirements for one building or structure shall be used to satisfy the minimum yard or lot area requirement for another building or structure.

B.

Front yard setback and corner lot streetside yard setback adjustment. The required front or streetside yard setback for a principal structure may be reduced on any lot where more than 50 percent of the same-type principal structures on the same block-face do not meet the required front yard or streetside yard setback. In such instances, the required front yard or streetside yard setback for the proposed structure shall be the average of all the same-type principal structures on the same block-face.

(Ord. No. 16-07, 6-20-2016)
