The boundaries of the base, overlay, and specific plan zones established by this title are not included in this title but are shown on the "Sectional Zoning Map of the City of Santa Barbara" (Official Zoning Map) maintained by the City Clerk. The Official Zoning Map, together with all legends, symbols, notations, references, zoning boundaries, map symbols, and other information on the maps, are adopted by the City Council and are hereby incorporated into this title by reference, together with any amendments previously or hereafter adopted, as though they are fully included here.
A. 
Application of Pre-Annexation Zoning. The City may apply pre-annexation zoning to unincorporated property located within the City's Sphere of Influence, consistent with the Santa Barbara General Plan. The pre-annexation zoning process shall comply with the provisions of Chapter 30.290, Zoning Upon Annexation. The zoning provisions and requirements so established shall become applicable at the same time that the annexation of such territory becomes effective.
B. 
Uncertainty of Boundaries. If an uncertainty exists as to the boundaries of any zone shown on the Official Zoning Map, the corresponding documented zoning descriptions shall govern.
1. 
In the case of unsubdivided property or where a zone boundary divides a lot and no dimensions are indicated, the location of such boundary shall be determined by the use of the scale appearing on the Official Zoning Map or by reference to City parceling maps if no boundary is specified by dimensions.
2. 
In the case of uncertainty as to interpretation of a zone boundary either documented by description or by the Official Zoning Map in the absence of a documented boundary description, the City Council shall, after recommendation of the Planning Commission, determine the location of the boundary in question.
C. 
Vacation or Abandonment.
1. 
Where any public street, alley, or thoroughfare is officially vacated or abandoned and the use of land therein is conveyed to the contiguous property, the zoning regulations applicable to the contiguous property shall apply to that portion of such street or alley added thereto by virtue of such vacation or abandonment.
2. 
Where any private right-of-way or easement of any railroad, railway, transportation or public utility company is vacated or abandoned and said property is unclassified, the zoning regulations applicable to the contiguous property shall apply to such vacated or abandoned land. If more than one zoning classification exists contiguous to the unclassified property, the Community Development Director shall apply the contiguous zoning classifications to the unclassified property as appropriate.
