For the purpose of this title the following zones are established in the City:

The boundaries for the zones listed in this title are appended hereto as an appendix to the ordinance codified in this title and marked as such with the area or areas of every zone, particularly described and are also indicated on maps entitled "Zoning Map of Yachats, Oregon," originals of which are on file in the office of the City Recorder, in a book or place kept for that purpose and open to public inspection and counterparts of which maps are in the office of the City Recorder and bear the same date as the passage of said ordinance and the number of said ordinance and each of the maps having endorsed thereon the signatures of the mayor and City Council members of the City Council and the chairman and secretary of the City Planning Commission, and the maps and any other information appertaining thereto, such as symbols, indications, notations, references and other information which appear in the maps are incorporated into and made a part of this title as much as if said matters and information set forth on and by the maps were fully described herein; provided that if there is a discrepancy between the maps and the description in the appendix, the description in the appendix shall control.

Zone boundaries, zone modifications, additions or reclassifications may be made at subsequent times and shall be made by amendment to this title, in accordance with the provisions of the title.

Maps of the zones or amendments to the location of zones adopted pursuant to Section 9.08.020 shall be prepared by the authority of the City Council. The map or amendment shall be dated with the effective date of the ordinance that adopts the amendment, together with the signatures of the chairman and secretary of the Planning Commission and the mayor and City Council members of the City Council, and the ordinance number of the ordinance which made the modification. A certified print of the original map and subsequent map shall be maintained without change in the office of the City Recorder in the book or place kept for that purpose; provided, however, that when an ordinance amends a previous ordinance so as to change the area of the zone on a map previously filed, the original map may be noted in the margin to show that a change was made together with the date of change and the map number or designation and amending ordinance number.

Unless otherwise specified, zone boundaries are section lines, subdivision lines, lot lines, center lines of street or railroad rights-of-way or such lines extended, or other similar lines.
