16.04.030 - Uncertainty of boundaries. ¶

Where uncertainty exists as to zone boundaries of any zone district shown upon the Zoning Map, or any part of such map, the following provisions shall apply:

A.

Where zone boundaries are shown as approximately following legal lot lines or the right-of-way lines of highways, streets, or alleys, such lines shall be the zone boundaries. In all other cases where a district abuts a highway, street, or alley, the zone boundaries shall extend to the centerline of the highway, street, or alley.

B.

In the case of unsubdivided property where a zone boundary divides a lot, the location of the boundary, unless the boundary is indicated by dimensions or legal description, shall be determined by use of the scale appearing on the Zoning Map.

C.

Where a public highway, street, or alley, or any portion of such highway, street or alley is officially vacated or abandoned, the vacated or abandoned highway, street or alley shall acquire the zone classification of the property to which the vacated or abandoned portion reverts.

D.

Any submerged lands to be reclaimed by fill for use as a land area shall be prezoned prior to City approval of the fill. The prezone shall be consistent with the General Plan. Permitted fill activities required in an emergency for the protection of public health or safety shall be exempt from this requirement.
