17.20.010 Purpose and applicability.¶
This chapter provides civic spaces throughout the city to properly serve the needs of residents and provide open space for recreation and to conserve natural habitats. This chapter establishes use regulations, development standards, and design standards for the Public and Quasi-Public, Parks and Recreation, and Open Space zoning districts as follows:
Public and Quasi—Public (PQP). The PQP zone is intended to provide for government-owned facilities, public and private schools and quasi-public uses such as churches and cemeteries, government buildings, utilities, libraries, and emergency transportation service. This zone implements the public/quasi-public general plan land use designation.
Parks and Recreation (PR). The PR zone is intended to provide for public parklands primarily designed for public recreation. It is applied to existing public parks, as well as passive open spaces. This zone implements the parks and recreation general plan land use designation.
Open Space (OS). The OS zone is intended to provide for natural open space areas that are devoted to the preservation of natural resources, the managed production of resources, outdoor recreation or public health and safety. Areas designated for open space are all associated with stream corridors that pass through or adjacent to the city including the Napa River, Sulphur Springs Creek, York Creek and Spring Creek. This zone implements the open space general plan land use designation. (Ord. 23-4 § 5 (Exh. A))
17.20.020 Use regulations.¶
Table 17.20.020(A): Use Regulations—Public and Open Space Zoning Districts, lists the uses permitted (“P”), permitted with a minor use permit (“MUP”) granted by a staff-level review, and permitted with a conditional use permit (“CUP”) granted at a public hearing. The right-hand column provides references to additional regulations beyond those of the base zoning district development and design standards.

17.20.040 Supplemental standards.¶
A. General Standards. All development is subject to the provisions of Division IV of this title, Citywide Standards.
B. Trash Enclosures. Unless specifically waived by the design review process described in Chapter 17.05, Planning Permits and Approvals, all projects must have a trash enclosure constructed of opaque materials and sufficiently sized to permit the storage, removal and replacement of standard commercial-size trash bins. No collection, storage or stacking of garbage, trash and refuse is permitted outside the trash enclosure. This requirement does not preclude the placement of individual trash containers on the parcel.
C. Development in the OS District. Limited development is permitted on open space-designated parcels along Sulphur Springs Creek west of the Crane Avenue Bridge. The development potential of open space-designated parcels will be determined in accordance with standards governing parcels designated agriculture in the general plan and zoned A-20. All development must be outside the stream corridor and structures must be set back from the creek’s edge consistent with the base standards, the Flood Plain Overlay district, and the California Department of Fish and Game standards.
