This Chapter establishes the zones applied to property within the City and adopts the City's Zoning Map.
D1-7 - Zoning Map and Zones
The Council hereby adopts the City of San Ramon Zoning Map (hereafter referred to as the "Zoning Map"), which is on file with the Department and the City Clerk. The Zoning Map is hereby incorporated into this Zoning Ordinance by reference as though it were fully included here.
A. Zones established. The City of San Ramon shall be divided into zones that implement the San Ramon General Plan, as follows.
Zoning designation system. The zones established by this Section are shown as symbols on the Zoning Map that consist of letters and numbers, organized as follows.
a. General land use indicator. Each zone symbol includes a letter that indicates the primary purpose of the zone in terms of land use types. For example, "RS" means that the primary land use type is single-family residential, though certain non-residential uses may also be allowed.
b. Residential density or dwelling type indicator. The land use symbol for a particular zone may include a number that identifies a sub-district with a specific range of dwelling unit densities or a type of dwelling. For example, "RS-12" identifies an area within the single-family residential zone where the minimum lot size is 12,000 square feet.
c. Overlay zone indicator. One or more overlay zone indicators may be appended to the primary zone indicator to identify any overlay zones that apply to a site. For example, "RS-12-L" would identify a residentially zoned site that is subject to a "Landmark" designation.
Zones. The zones shown in Table 1-1 are hereby established, and shall be shown on the Zoning Map.
B. Interpretation of zone boundaries. If there is uncertainty about the location of any zone boundary shown on the official Zoning Map, the location of the boundary shall be determined by the Zoning Administrator as follows.
- A zone boundary shown as approximately following a property line shall be construed to follow the property line.

On unsubdivided land, or where a zone boundary divides a lot, the location of the boundary shall be determined by using the scale on the Zoning Map, unless dimensions printed on the map indicate the boundary location.
A zone boundary shown as approximately following the right-of-way line of a freeway, street, railroad, or other identifiable boundary line shall be construed to follow the right-of-way or other boundary line.
A zone boundary shown as located within the right-of-way line of a freeway, street, railroad, or other identifiable boundary line shall be construed to follow the centerline of the right-of-way or boundary line.
If any uncertainty remains about the location of a zone boundary or other feature shown on the zoning map, the location shall be determined by the Zoning Administrator.
- C. Development on a lot divided by zone boundaries. If a lot is divided by a zone boundary, the regulations of this Zoning Ordinance that apply to each zone shall be applied to the area within each district, and no use other than parking serving a principal use on the site shall be located in a district in which it is not a permitted or conditional use in Division D2 (Allowable Land Uses and Zoning Standards).
