   Land uses, parcel level zoning, and development standards within a specific plan zone shall be as prescribed in the specific plan.
4. All notations, references, and other information shown in the above-referenced specific plans are incorporated by reference and shall be deemed as much a part of this Title 19 as if the matter and information set forth in the plan were fully described in this chapter. All terms not otherwise defined in a specific plan shall have the meaning set forth in this Title 19. Notwithstanding the provisions or standards set forth in this Title 19, individual specific plans may establish additional or separate provisions and standards for said plan area, including, without limitation, standards for: regulating physical development, granting greater density bonuses than otherwise required, requiring below-market-rate housing production, and processing of subsequent applications. In the event of a conflict between the terms, conditions, requirements, policies, or other provisions of a specific plan and this Title 19, the specific plan shall take precedence.

(Ord. 19-2187, § 3 (part), 2019; Ord. 18-2177, § 3 (part), 2018; Ord. 2085, § 2 (part), 2011; Ord. 1601, Exh. A (part), 1992; Ord. 24-2261, § 1 (part), 2024)

Reference within the title to residential districts generally and as a grouping, includes all districts identified in the section. Where references are made to more restrictive or less restrictive residential districts, such references shall apply sequentially between the most restrictive and the least restrictive.

(Ord. 2085, § 2 (part), 2011; Ord. 1601, Exh. A (part), 1992; Ord. 24-2261, § 1 (part), 2024)

1. The boundaries of districts established by this title shall be shown upon the zoning map. The zoning map, and all amendments, changes, and extensions thereof, and all legends, symbols, notations, references, and other matters shown thereon shall be a part of this title.
2. The zoning map, as currently effective, and a record of all amendments, changes and extensions thereof, shall be maintained as a public record in the office of the Director of Community Development.
3. The boundaries of each district as shown upon the zoning map, or amendments thereto, are adopted by the ordinance codified in this title, and the specific regulations established by this title for each general district and all other regulations applicable therein as set forth in this title are established and declared to be in effect upon all portions of lands included within the boundaries of each and every district as shown upon the zoning map.

(Ord. 19-2187, § 3 (part), 2019; Ord. 2085, § 2 (part), 2011; Ord. 1601, Exh. A (part), 1992)

All lands now or hereafter included within the incorporated territory of the City, which are not included within a general district shown on the zoning map of the City or are not shown as prezoned to a general district in accord with applicable provisions of this title, shall constitute R-1 single-family residence districts.

(Ord. 2085, § 2 (part), 2011; Ord. 1601, Exh. A (part), 1992)

The following rules shall apply in the determination of the boundaries of any district shown on the zoning map:

1. Where boundaries are indicated as approximately following street and alley lines, or other identifiable boundary lines, such lines shall be construed to be the district boundary. Where such boundaries are indicated as within street or alley lines, or within identifiable rights-of-way or creeks, the centerline thereof shall be the district boundary.
2. In unsubdivided property, and where a district boundary divides a lot, the location of the district boundary, unless the same is indicated by dimensions, shall be determined by use of the scale appearing on the zoning map.
3. A symbol, or symbols, indicating the classification of property on a zoning map shall in each instance apply to the whole of the area within the district boundaries.
4. Where a public street, alley or right-of-way is officially vacated or abandoned, the regulations applicable to this abutting property shall apply equally to each half of such vacated or abandoned street, alley or right-of-way.
5. Should any uncertainty remain as to the location or meaning of a boundary or other feature indicated upon a zoning map, said location or meaning shall be determined by the Director of Community Development.

(Ord. 2085, § 2 (part), 2011; Ord. 1601, Exh. A (part), 1992)

Whenever it is found that a lot or site is divided by a boundary between districts, the provisions of the zoning regulations applicable within each district shall apply only to the portion of this site situated in each separate district.

(Ord. 19-2187, § 3 (part), 2019; Ord. 2085, § 2 (part), 2011; Ord. 1601, Exh. A (part), 1992; Ord. 25-2277, Exh. A (part), 2025)
