The purpose of this chapter is to establish districts wherein compatible uses of land may be grouped to create, protect, and maintain a livable environment; to stabilize and protect the uses contained within the districts; to allow a maximum degree of latitude within the districts, conduct profitable business, or contribute to the economy of the Columbia Falls area. It is also the purpose of this chapter to make it possible to more efficiently and economically design and install all physical public service facilities in terms of size and capacity to adequately and permanently meet needs resulting from a defined intensity of land use, providing for the health, safety, prosperity, and well-being of the total area.

For the purpose of applying these regulations to the zoning jurisdictional area of the city of Columbia Falls, said area is divided into the following use districts:

The location and boundaries of the use districts are established as they are shown on the map entitled "The Columbia Falls Jurisdictional Area Official Zoning Map," which shall become effective with and as an inseparable part of this title as of the date of adoption by the city council of the city. This title is invalid without said map and, conversely, the map is deemed to be invalid without this title.

Where uncertainty exists as to the boundaries of any of the aforesaid districts on said map, the following rules shall apply. Where more than one of the rules are applicable in any given situation, the first enumerated rule shall prevail:

1. Where a district boundary line is shown by a specific dimension, such specific dimension shall control.
2. Where a district boundary line is located within or along a street, alley, right-of-way, or waterway, the district boundary line shall be deemed to be the center of such street, alley, right-of-way, or waterway, or extension therefrom.
3. Where a district boundary line is shown as approximately following platted lot lines, the district boundary line shall be deemed to coincide with such platted lot lines.
4. If none of the above rules is found to be sufficient to resolve the question, the zoning administrator:
   1. Shall, using a scaled rule, measure a line drawn on the map, take note of the dimensions and record such dimensions on the map, thus establishing for future reference the location of said boundary in a manner to be consistent; or
   2. May make a decision, based on his knowledge and understanding of this title, specifically determining the location of the boundary in question. Any such decision becomes fixed unless amended by the city council, and a reference shall be entered on the map showing the date such decision was made. The zoning administrator shall keep on permanent file any such decision which may be altered or amended by the city council.

District boundaries shall, except for unique conditions or circumstances, take into consideration property boundaries platted and every effort shall be made to not divide a platted lot, parcel, or tract of land into two or more use districts.

Within the various use districts, as defined in Chapter 18.314, and as indicated on the official zoning map of the planning area or parts thereof, no land, building, or structure shall be used and no building or structure shall be erected, reconstructed, or structurally altered for any purpose except as allowed in the district in which the building, land, or use is located. Permitted uses in the various districts are located in Chapters 18.317 through 18.352. No land, building, or structure which is intended to be, in whole or in part, a conditional use shall be erected or used without specific approval of the city council. The procedures outlined in Chapter 18.310 shall be used by the planning board and the city council as a guide in granting or denying approval of a conditional use. Any variance from the dimensional regulations shall require prior, specific approval of the board of adjustment as outlined in Chapter 18.309.

In the interpretation of Chapter 18.317 through Chapter 18.352, where a use is not specifically listed, its status shall, upon application, be determined by the planning board by reference to that listed use, if any, which is so like the requested use in purpose, function, character, and affect as to be substantially similar to the listed use.

Except as otherwise specified in these regulations, only one primary use shall be allowed per tract of record in the following zones: CSAG-10, CSAG-5, CR-1, CR-2, CR-3, CR-4, CR-5, and CRA-1. Multiple uses may be allowed on single lots in other zoning districts provided they meet the bulk, dimensional, and parking requirements of the underlying zoning classification.

The following types of structures or structural parts are not subject to the building height limitations of this chapter: church spires, steeples and belfries; they will in no case exceed sixty-five (65) feet from the ground with one (1) foot of setback for each foot of height measured from the nearest property line.
