In addition to the general purposes listed in Chapter 17.02, the specific purposes of the public, quasi-public, parks and open space, and agricultural resource districts are as follows:
A. 
To provide appropriately located land throughout the city for public facilities and parks.
B. 
To provide opportunities for recreational uses in public parks.
C. 
To protect and conserve identified sensitive lands within the RUL.
D. 
The additional purposes of each district follow:
1. 
Public, Quasi-Public Schools and Health Facilities District (PQ). The public, quasi-public schools and health facilities district provides for public and quasi-public properties dedicated to community serving purposes, such as public schools of all levels, private schools with a significant enrollment, major community health facilities and related community service facilities. Public and quasipublic uses may be located in any zoning district in the city as a conditional use. This PQ district is intended for public and quasi-public uses which because of their size, location and significance are designated "Public Serving" in the General Plan.
The city's authority to regulate land use activities of other government entities is limited by state and federal law, thus applicability of local PQ zoning may only be established on a case-by-case basis. Because of the wide variety of possible public and quasi-public uses, all public and quasipublic uses shall require a use permit, to the extent that such uses and/or entities are subject to the zoning authority of the city.
2. 
Public, Quasi-Public District (PQ-P). This public, quasi-public district provides for publicly owned properties dedicated to community serving purposes, including government offices, public safety facilities and related community service facilities. Conference, exhibition, entertainment and other public gathering uses may also occur in large facilities such as those at the Napa Valley Expo. Public and quasi-public uses may also be located in any zoning district in the city as a conditional use. This PQ-P district is intended for public and quasi-public uses which because of their size, location and significance are designated "Public Serving" in the General Plan.
The city's authority to regulate land use activities of other government entities is limited by state and federal law, thus applicability of local PQ-P zoning may only be established on a case-by-case basis. Because of the wide variety of possible public and quasi-public uses, all public and quasi-public uses shall require a use permit, to the extent that such uses and/or entities are subject to the zoning authority of the city, except for emergency shelters which shall be permitted under state law (SB 2) provisions.
3. 
Downtown Public (DP). The Downtown Public land use district provides for public and quasipublic uses dedicated to community-serving purposes such as government offices and related community service facilities. County uses such as the Napa County administrative and courthouse complex and adjoining jail are included in the Downtown Public district, as are uses that support Downtown commerce and living such as the public library, public parking facilities and Napa City Hall. The Downtown Public district also provides for appropriately located public lands devoted to public open spaces and trails.
4. 
Parks and Open Space District (POS). The parks and open space district provides for appropriately located public lands throughout the city devoted to citywide, community and neighborhood parks and trails, and large tracts of publicly owned open space land including greenways, parkways and nature preserves. This district may also be applied to farms owned and operated by nonprofit organizations used for educational purposes and open to the public.
5. 
Downtown Parks and Open Space (DPOS). The Downtown Parks and Open Space land use district provides for passive and active recreational uses, as well as act as an amenity for public gatherings and events downtown.
6. 
Agricultural Resource District (AR). The agricultural resource district is applied to lands within the RUL designated "Resource Area" or "Greenbelt" by the Napa General Plan. These are sensitive lands within the RUL that require special standards due to viewshed, resource, habitat, geotechnical or other considerations that further the resource protection goals of the General Plan. Primary purposes are:
a. 
To protect sensitive lands within the RUL that are not appropriate for urban development due to viewshed, resource, habitat, geotechnical or other considerations and are intended to remain unchanged or in very low intensity agricultural, private open space or residential use;
b. 
To retain large, agriculturally viable parcels and conserve the region's economically important agricultural resources;
c. 
To meet Government Code requirements for open space zoning (in combination with the parks and open space district).
