All of the incorporated territory of the city is divided into areas known as "Zones" designated in Chapter 17.08 within which separate uniform regulations are imposed. The boundaries of these zones are shown and described on a map entitled "Zoning, City of Sonora." This map is made a part of the ordinance codified in this title. A copy of this map, showing all the current amendments thereof, shall be kept and may be consulted in the office of the building department.

(Ord. 376 § 10-2-4(A), 1967.)

Zone boundaries shown on the zoning map shall be further determined as follows:

A.

The boundary of a zone abutting the city limits shall be such limits.

B.

Where a zone boundary is shown as approximately following a property line, a section line, or the line of a legal subdivision of a section, or where such boundary is located not farther than fifteen feet from such lines, the zone boundary shall coincide with such lines.

C.

Unless otherwise shown, the boundary of a zone abutting a street, waterway, railroad, or similar Right-of-Way shall be the centerline of such Right-of-Way, and the side boundaries shall extend to the centerline normally to such Right-of-Way.

D.

In all other cases, the location of a zone boundary shall be determined by the use of the scale appearing on the map and of the surveys, records, and other documents necessary to clarify the description of land and boundaries shown on the map.

E.

Zone boundaries shall extend vertically upward and downward from the ground.

F.

Where a zone boundary divides a parcel under one ownership in existence prior to the effective date of the zone boundary and when not less than half the area of such parcel lies in the less restricted zone, the regulations for the less restricted zone shall apply to the remainder of such parcel up to a distance of not more than thirty feet.

G.

In case uncertainty exists on the location of a zone boundary, the commission, on request or on its own initiative, shall determine the exact location of such a boundary.
