Where uncertainty exists as to the boundaries of any district shown on the zoning map, the following rules shall apply:
A. 
Where such boundaries are indicated as approximately following property, street or alley lines, such lines shall be construed to be such boundaries;
B. 
In subdivided property and where a district boundary divides a lot, the location of such boundaries, unless the same are indicated by dimensions, shall be determined by use of the scale appearing on the zoning map;
C. 
A symbol indicating the classification of property on the zoning map shall in each instance apply to the whole of the area within the district boundaries, unless otherwise noted on said map;
D. 
Where a public street, alley or parcel of land is officially vacated or abandoned, the regulations applicable to abutting property shall apply equally to such vacant or abandoned street or alley;
E. 
Where one land ownership is divided by a district boundary, the total ownership may be placed in either district by approval of a rezoning application.

(Ord. 702 § 4, 2014)
A. 
It is recognized that in the development of a comprehensive zoning ordinance, not all uses of land can be listed, nor all future uses be anticipated; or a "use" may have been omitted from the list of those specified as permissible in each of the various zones herein designated; or ambiguity may arise concerning the appropriate classification of a particular use within the meaning and intent of this title. Therefore, the phrase "unless determined by the Planning Commission to be similar in nature" shall appear under "uses permitted" in each zone.
B. 
The Planning Commission shall make all the following findings when permitting an unlisted use in a zoning district or classifying an unlisted use:
1. 
That the use is in keeping with the stated intent and purpose of the zoning district;
2. 
That investigations have disclosed that the subject use and its operation are compatible with the uses permitted in the zoning district within which it is proposed to be located;
3. 
That the subject use is similar to one or more uses permitted in the zoning district within which it is proposed to be located; and
4. 
That the subject use will not cause substantial injury to the health, safety, or welfare of the occupants or their property in the zoning district in which it is proposed to be located.
(Ord. 702 § 4, 2014)
