Section 3.2. BOUNDARIES AND OFFICIAL MAP.

The boundaries of these districts are indicated and established as shown upon maps designated as the official zoning map of Rock Valley, Iowa, which, with all the notations, designations, references, and other matters shown thereon, shall be as much a part of this zoning ordinance as if fully described and set forth herein. Amendments, supplements, or changes of the boundaries of districts as shown on the official zoning map shall be made by an ordinance amending this zoning ordinance. The amending ordinance shall refer to the official zoning map and shall set out the identification of the area affected by legal description, and identify the zoning district as the same exists and the new district designation applicable to said property. Said ordinance shall, after adoption and publication, be recorded by the Sioux County Recorder as other ordinances and a certified copy thereof be attached to the official zoning map. Such amendatory ordinance shall, however, not repeal or reenact said map, but only amend it. The official zoning map, together with amending ordinances, shall be the final authority as to the current zoning status of land areas, buildings, and other structures in the city.

The official zoning map shall be on file in a convenient place in the municipal office of the City of Rock Valley and all references hereafter to said official map described hereinabove. In the event that the official zoning map becomes damaged, destroyed, lost or difficult to interpret because of use or the nature of a number of changes and additions, the City Council may, by resolution, adopt a new official zoning map which shall supersede the prior zoning map. The new official zoning map may correct drafting or other errors or omissions in the prior map, but no such corrections shall have the effect of amending the original official zoning map or any subsequent amendments thereof.
