17.06.030 - Zoning Map.¶
The boundaries, designations, and locations of the zones established by this Zoning Code shall be shown upon the map(s) entitled "Zoning Map" and referred to in this Zoning Code as the Zoning Map. Any additional maps (e.g., setback map, height map) adopted shall also be a part of this Zoning Code by reference. This Zoning Code, together with the Zoning Map, is adopted in compliance with current state planning, zoning, and development laws. Amendments to the existing zone boundaries of any identified zones shall be made by ordinance in compliance with Chapter 17.72 (Amendments).
17.06.040 - Rights-of-Way and Vacated Boundary Lines.¶
Where a public street or alley is officially abandoned or vacated by the Council, the property encompassed by areas associated with the abandoned/vacated street or alley shall be included within the zone(s) of the adjoining properties. If the adjoining properties are in different zones, the boundary lines shall be the centerline of the former street or alley. In the event the street, alley, or right-of-way was a boundary between two (2) or more different zones, the new zone or zone boundary shall be the property line that is created by the abandonment or vacation.
17.06.050 - Uncertainty of Boundaries.¶
Interpretation of Zone Boundaries. If there is uncertainty about the location of any zone boundary shown on the official Zoning Map, the precise location of the boundary shall be determined by the Director. [Source: 17.04.020.B]
Where zone boundaries approximately follow lot, alley, or street lines, the lot lines and street and alley centerlines shall be construed as the zone boundaries;
If a zone boundary divides a parcel and the boundary line location is not specified by distances printed on the Zoning Map, the location of the boundary will be determined by using the scale appearing on the zoning map; and
Where a public street or alley is officially vacated or abandoned, the property that was formerly in the street or alley will be included within the zone of the adjoining property on either side of the centerline of the vacated or abandoned street or alley.
17.06.060 - Classification of Annexed Lands.¶
Zoning Map Amendment. Whenever it is deemed that the zone of annexed lands is inconsistent with adopted General Plan land use policy or other applicable Town policies, the Planning Commission may recommend, and the Council may adopt the zone classification(s) which shall apply to the annexed lands in the manner specified in Chapter 17.72 (Amendments).
