The districts are bounded as shown on a map entitled, “Official Zoning Map,” which together with all explanatory material thereon, is hereby adopted by reference and declared to be a part of this title.

The official zoning map for the unincorporated portion of the Pasco Urban Area shall be maintained in the Franklin County Planning Office. The official zoning map for that portion of the Pasco Urban Area within the City limits shall be maintained in the City of Pasco Planning Office.

Each official zoning map shall be identified by the signatures of the legislative body having jurisdiction and the date of adoption. The official zoning map maintained by the City shall be the final authority as to the current zoning status of land in the City.

In accordance with the provisions of this title, if changes are made in district boundaries or other matters portrayed on the official zoning map, such changes shall be made on the official zoning map promptly after the amendment has been approved by the City Council. The amending ordinance shall provide that they have been duly entered upon the official zoning map.

In the event that the official zoning map becomes damaged, destroyed, or lost, or difficult to interpret because of the nature or number of changes and additions, the City Council may, by ordinance, adopt a new official zoning map which shall supersede the prior official zoning map.

No changes of any nature shall be made in the official zoning map or matter shown thereon except in conformity with the procedure set forth in this title. Any unauthorized change of whatever kind by any person or persons shall be considered a violation of this title and is unlawful. [Ord. 3354 § 2, 1999; Code 1970 § 25.16.020.]
