Sec. 20.604.050 - Uncertainties in Zone Boundaries.

Where uncertainty exists as to any boundary of any Zoning District shown on the Town of Mendocino Zoning Map, the Coastal Permit Administrator shall apply the following rules to resolve such uncertainty:

(A) Where Zoning District boundaries approximately follow lot, alley, or street lines, such lot lines or street and alley centerlines shall be construed as the district boundaries.

(B) If a Zoning District boundary divides a lot, and the boundary line location is not otherwise designated or described, the location of the boundary shall be determined by use of scale appearing on the Zoning Map.

(C) Where a public street or alley is officially vacated or abandoned pursuant to a coastal development permit, the area formerly in said street or alley shall be included within the Zoning District or Zoning Districts of the adjoining lot or lots of said vacated or abandoned street or alley, to the centerline of such street or alley.

(D) The purpose of parcels with split zoning is to provide a buffer between residential areas and more intense uses, such as the Commercial and Mixed Use Zoning Districts. Where a parcel is bisected by a Commercial/Town Residential or other Residential zoning district boundary, or Mixed Use/Town Residential or other Residential zoning district boundary, (1) the regulations of each district shall apply separately to that portion of the parcel lying in either district, (2) the zoning district boundary shall be considered a de facto parcel line for the purposes of determining setbacks, lot coverage and other development regulations of this division, and (3) the provisions or requirements of either district shall not apply to the entire parcel.

(E) Where further uncertainty exists, the Planning Commission, upon written request or on its own motion, shall determine the location of the boundary in question, giving due consideration to the location indicated on the Zoning Map and the purposes set forth in the Base Zone District Regulations.
