  • (a) The classes of districts and certain combinations thereof designated in Chapter 18.08 may be established by ordinance insofar as the designations, locations, and boundaries thereof are set forth and indicated by written description, or in various sectional district maps which may hereafter be filed and adopted and which show such designations, locations and boundaries of certain said districts. Said maps and all notations, references, data, and other information shown thereon shall become a part of this title and subject thereto, and all such written descriptions and maps shall be designated as subsections of this section.

  • (b) Where uncertainty exists as to the boundaries of any of the districts designated in Chapter 18.08 as described or as shown on said sectional district maps, the following shall apply:

    • (1) Where such boundaries are indicated as approximately following street and alley lines, such street and alley lines shall be construed to be such boundaries.

    • (2) Where such boundaries are indicated as approximately following lot lines, such lot lines shall be construed to be such boundaries.

    • (3) In subdivided property and where a district boundary divides a lot, the location of any such boundary, unless the same is indicated by dimensions shown upon said sectional district maps, shall be determined by the use of the scale appearing on such sectional district maps.

  • (4) In case further uncertainty exists, the planning commission, upon written application or upon its own motion, shall determine the location of such boundaries.
