In accordance with section 414 of the Iowa Code, as the same now exists or may be hereafter amended, superseded or replaced by subsequent sections of said Iowa Code, the council herewith provides the following manner to amend, supplement or change the boundaries as shown on said zoning "district map". Such amendments, supplements or changes shall be set out in an amending ordinance identifying the property by legal description and identifying the zoning district as the same exists, and the new district to be established for said property. Such ordinance, after adoption and publication shall be then recorded by the city clerk as other ordinances, and a certified copy of said ordinance be attached to the "district map", shall be kept continually up to date by proper notation thereon. (Ord. B-39, 1969; amd. Ord. B-203, 10-21-1975)
Such amending ordinance shall make reference to the zoning ordinance and zoning district map, and shall thereafter constitute a part of the city zoning ordinance. Such amending ordinance shall not per se repeal or reenact said district map, and said map shall continue to exist in full force and effect and to define and establish the boundaries as the same exist on said map, except that said map is made subservient and inferior to all subsequent ordinances amending, supplementing or changing boundaries adopted in the manner as above provided. After such subsequent ordinances are adopted and published as above provided, the boundaries and zoning districts as defined in said subsequent ordinances shall supersede the district and boundaries as shown on said district map for the particular property described in the subsequent ordinances. Further, such subsequent ordinances shall be considered as special ordinances, and not required to be set out at length in the municipal code.
That said map shall be updated and a new district map integrated, reenacted and reproduced in multiple copies at least once each five (5) years. (Ord. B-39, 1969)
