A. 
All lands not classified according to the classification in TMC Section 18.08.010 on the official zoning map, and all lands, if any, of the City not shown on the official zoning map, shall be considered unclassified and, pending future classification, shall be subject to the restrictions and regulations of the CR District.
(Ord. 2741 § 4 (part), 2024; Ord. 2762 § 3, 2025)
A. 
The boundaries of the use districts as outlined in TMC Section 18.08.010 are shown on the official zoning map (Figure 18-10) which, together with all explanatory matters thereon, is hereby adopted by reference and declared to be a part of this title. The regulations of this title governing the uses of land, buildings and structures, the height of buildings and structures, the sizes of yards about buildings and structures, and other matters set forth in this title are hereby established and declared to be in effect upon all land included within the boundaries of each and every district shown upon said zoning map.
B. 
The boundaries of the use districts shall be determined and defined or redefined from time to time, by the adoption of district maps covering the City showing the geographical area and location of the districts. Each district map shall be, upon its final adoption, a part of this title, and the map and all notations, references and other information shown thereon, thereafter shall be made a part of this title as though all matters and information set forth on the map were fully described herein.
C. 
The official zoning map shall be identified by the signature of the Mayor, attested by the City Clerk and shall bear the seal of the City of Tukwila. The original of the official zoning map shall be retained in the office of the City Clerk.

(Ord. 2741 § 4 (part), 2024)
A. 
When uncertainty exists as to the boundaries of any use district shown on the official zoning map, the following rules of interpretation shall apply:
1. 
Where district boundaries are indicated as approximately following the centerline of streets, alleys, highways, structure or railroad tracts, the actual centerline shall be construed to be the boundary;
2. 
Where district boundaries are indicated as running approximately parallel to the centerline of a street, the boundary line shall be construed to be parallel to the centerline of the street;
3. 
Where district boundaries are indicated on such map as approximately following the lot or tract lines, the actual lot or tract lines shall be construed to be the boundary of such use district;
4. 
Where a district boundary on the official zoning map divides a tract in unsubdivided property, the location of the use district boundary, unless the same is indicated by dimensions thereon, shall be determined by use of the scale appearing on the official zoning map;
5. 
Unmapped shorelands shall be considered to be within the same land use district as the adjacent upland as shown on the official zoning map;
6. 
Where a public street or alley is officially vacated or abandoned, the regulations applicable to the abutting property to which the vacated portion reverts shall apply to such vacated or abandoned street or alley;
7. 
Where a district boundary line divides a lot which was in single ownership at the time of passage of this title, the Hearing Examiner may permit, as a special exception, the extension of the regulations for either portion of the lot not to exceed 50 feet beyond the district line into the remaining portion of the lot;
8. 
In case uncertainty exists which cannot be determined by application of the foregoing rules, the Hearing Examiner shall determine the location of such use district boundaries. Applications for such special exceptions shall be a Type 3 decision processed pursuant to TMC Section 18.108.030.
