84-2.002 - Zoning map adopted.¶
(a) The location and boundaries of the land use districts established by this division are shown on a map entitled "Zoning Map of Contra Costa County." The zoning map, including symbols, boundaries, notations, legends, and all other information shown on the zoning map, is adopted by this reference and incorporated into this division. This adoption of the zoning map does not change the land use classification of any land.
(b) The zoning map, certified by the community development director, is on file with the clerk of the board of supervisors. A paper version and a digital version of the zoning map are available for public inspection at the community development department.
(c) When a zoning ordinance or amendment to a zoning ordinance changes any property from one zone to another, the community development director will record the change on the zoning map. All changes so recorded are made a part of the zoning map and incorporated into this division.
(d) If the boundaries of a land use district are not clearly identifiable on the zoning map, the following rules of interpretation apply:
(1) Where a boundary line appears to follow a street, highway, or right-of-way, the boundary is deemed to be the centerline of the street, highway or right-of-way.
(2) Where a boundary line appears to follow a lot line or property line, the boundary is deemed to be the lot line or property line.
(3) Where a boundary line appears to divide a lot or parcel, the location of the boundary is determined by the scale contained on the zoning map.
(4) Where there is an obvious mistake that can be corrected by reference to documents on file with the community development department, or where there is a minor discrepancy between the paper version and the digital version of the zoning map, the community development director may identify the boundary.
(5) If any further uncertainty exists, the planning commission will determine the location of boundaries.
