The boundaries for the zones listed in DCC Title 18 are indicated on the Deschutes County Zoning Map which is hereby adopted by reference. The boundaries shall be modified subject to zoning map amendments which shall be adopted by reference.

A zoning map amendment adopted by DCC 18.12.020, above, or by an amendment thereto shall be prepared by authority of the Planning Director or Hearings Body or Board of County Commissioners. The map or map amendment shall be dated with the effective date of the order or ordinance that adopts the map or map amendment. The Deschutes County zoning map exists in official replica form as an electronic map layer within the County geographic information system. The official copy of the electronic version of the zoning map shall contain a legal description of the area to be amended, a map reflecting the previous zoning and a map of the amendment printed onto permanent media, recorded and maintained in the office of the County Clerk. An original printed version of the adopted map or map amendment signed by the Board of County Commissioners shall be maintained in the office of the County Clerk.

Unless otherwise specified, zone boundaries are section lines, subdivision lines, lot lines, center lines of street or railroad rights of way, water courses, ridges or rimrocks, other readily recognizable or identifiable natural features, or the extension of such lines. In case of any dispute regarding the zoning classification of property subject to the County code, the original ordinance with map exhibit contained in the official county records will control. Whenever uncertainty exists as to the boundary of a zone as shown on the zoning map or amendment thereto, the following rules shall apply:

1. Where a boundary line is indicated as following a street, alley, canal, or railroad right of way, it shall be construed as following the centerline of such right of way.
2. Where a boundary line follows or approximately coincides with a section lines or division thereof, lot, parcel, or property ownership line, it shall be construed as following such line.
3. If a zone boundary as shown on the zoning map divides a lot or parcel between two zones, the entire lot or parcel shall be deemed to be in the zone in which the greater area of the lot or parcel lies, provided that this property line adjustment involves a distance not exceeding 100 feet from the mapped zone boundary. DCC 18.12.040 does not apply to areas zoned flood plain.
