Open Space (OS) District Setback Requirements in Concord
In the Open Space (OS) district of the city of Concord, there are no universally defined numerical setback distances for all structures. Instead, the Concord Development Code requires that development on any parcel zoned as Open Space (OS) comply with development standards that are determined by the review authority based on the specific site and project conditions, unless otherwise specified by other applicable provisions of the development code.
Setback Requirements and Procedures for the OS District
The Concord Development Code classifies the Open Space (OS) district under the "Community Land Districts" category [Section 18.15.020]. The city of Concord generally applies these standards to land that is typically unaltered, maintains natural resources and scenic value, and may be either privately or publicly owned [Section 18.60.010].
Because the OS district is intended for land that is largely undeveloped, the Concord Development Code does not provide a standard table of numerical setback distances for structures in this district. Instead, the following regulatory framework applies:
Determination of Setbacks
For development within the Open Space (OS) district, the review authority is responsible for determining applicable setbacks on a case-by-case basis [Section 18.60.030].
- Conformance with Standards: New uses and structures must be designed, constructed, and established in compliance with the requirements specified by the development permit or approval [Section 18.60.030].
- Abutting Districts: If a permit does not regulate a specific development feature (such as a setback) or if no permit is required, the regulations of the abutting district shall apply to each adjacent portion of the property, as applicable [Section 18.60.030].
- Agricultural Use Exception: Outdoor storage in the Open Space (OS) district is permitted if it is associated with a permitted agricultural use and is not located within a required setback [Table 18.150.120].
General Development Standards Applicable to OS
While specific setbacks are determined on a case-by-case basis, all development in the Open Space (OS) district must comply with the broader General Development Standards established in the Concord Development Code, which include:
| Standard Type | Requirement Summary |
|---|---|
| Outdoor Storage | Permitted only if associated with a permitted agricultural use and located outside of a required setback [Table 18.150.120]. |
| Traffic Visibility | No fence, wall, structure, or vegetation exceeding three feet in height is permitted within a designated visibility triangle at intersections [Section 18.150.170]. |
| Grading | Design and site development review is required for grading activities, subject to specific exemptions [Section 18.150.060]. |
