Overview of the Open Space (OS) Zoning District in Concord
The Open Space (OS) zoning district is designated for land that is generally unaltered, possessing natural resources and scenic value, and may be privately or publicly owned [Section 18.60.010]. Uses allowed within the Open Space (OS) district are limited to those permitted under the community land zoning classification, and development is subject to specific performance standards and environmental protections to maintain the district's ecological integrity.
Permitted Uses in the Open Space (OS) District
The Open Space (OS) district is intended to preserve land in its natural state, and therefore, the list of permitted uses is restricted. According to the land use classification tables, the following uses are permitted in the Open Space (OS) district:
