The boundaries of the zoning districts shall be shown upon the zoning district map, which is a part of this appendix. ^[2] The zoning district map shall be located in the office of the City Clerk of St. Clair, Missouri. The zoning district map and all notations, references, and other information shown thereon were all set forth or described herein.

Where uncertainty exists with respect to the boundaries of the zoning districts as shown on the zoning district map, the following rules shall apply:

(a)

Where the districts designated on the map accompanying and made a part of this appendix are bounded approximately by street or alley lines, the center line of the street or alley shall be construed to the boundary of the district.

(b)

Where the district boundaries are not otherwise indicated, and where the property has been or may hereafter be divided into blocks and lots, the zoning district boundaries shall be construed to be the lot lines. Where the districts designated on the zoning district map are bounded approximately by lot lines, said lot lines shall be construed to be the boundary of the zoning districts unless the boundaries are otherwise indicated on the zoning district map.

(c)

In unsubdivided property, the zoning district boundary lines on the zoning district map accompanying and made a part of this appendix shall be determined by the use of the scale appearing on the zoning district map or the legal description defining such zoning.

(d)

Except as may be preempted by applicable law, or otherwise provided by subsequent site-specific zoning enactment of the city, the zoning of the area within the streets and alleys and other public rights-of-way within the city are the most restrictive adjacent zoning district, and for purposes of delineation and clarification shall be deemed zoned subject to the R-1a Single-Family Estate Residential district, except for any rights-of-way that are not within 1,000 feet of a property zoned residential or used for a residential dwelling which shall be deemed zoned "C-1" Neighborhood Business District/Limited Commercial district.
