(A) The designations, locations and boundaries of the respective districts and certain combinations thereof described in this Chapter are established as shown by appropriate color designations, symbol or short title identification upon the Multnomah County Zoning Map. The Zoning Map consists of a series of bound and indexed Sectional Zoning Maps numbered sheets l through 828 until such time as the districts and subdistricts depicted on each respective Sectional Zoning Map are replaced by maps generated as electronic layers within a Geographic Information System (GIS).

The Zoning Map and all pertinent information shown thereon is incorporated herein and is to be deemed as much a part of this Chapter as if fully setforth; however, if a conflict appears between the Zoning Map and the written portion of this Chapter, the written portion shall control.
