A. 
The following are purpose statements for each of the City's base zoning districts:
1. 
A-1 Agricultural. The purpose of the A-1 District is to maintain and conserve agricultural lands which are historically valuable for crop and animal production, pastureland and natural habitat for wildlife. This district is intended for large agricultural parcels but does allow farm-related dwellings.
2. 
R-1 Low-Density Residential. The purpose of the R-1 District is to encourage the establishment and preservation of neighborhoods with single-household detached dwellings.
3. 
R-2 Low-Medium Density Residential. The purpose of the R-2 District is to accommodate single-household detached dwellings, two-household dwellings, and zero-lot-line dwellings.
4. 
R-3 Medium-Density Residential. The purpose of the R-3 District is to accommodate a mixture of single-household housing types, including single-household dwellings, two-household dwellings, zero-lot-line dwellings, and attached townhouses and row houses (up to eight units per parcel).
5. 
R-4 High-Density Residential. The purpose of the R-4 District is to accommodate a range of medium-density and high-density housing types, including row houses, townhouses, and apartments.
6. 
R-MMH Manufactured and Mobile Home. The purpose of the R-MMH District is to establish and preserve neighborhoods comprised of manufactured homes or mobile homes.
7. 
B-1 Neighborhood Business. The purpose of the B-1 District is to accommodate small-scale commercial uses that are primarily intended to serve adjacent neighborhoods.
8. 
B-2 Community Business. The purpose of the B-2 District is to provide shopping areas along major community roadways with moderately scaled commercial uses that are primarily intended to serve the local community.
9. 
B-3 Regional Business. The purpose of the B-3 District is to accommodate large-scale commercial uses that benefit from access and visibility to major regional highways and are primarily intended to serve the regional market area.
10. 
MU-N Mixed-Use Neighborhood. The purpose of the MU-N District is to provide areas for the development and redevelopment of land based on the design principles of traditional neighborhoods including a mix of complementary uses consisting of residential, commercial, civic, institutional, and open space uses in close proximity to each other; a mix of housing styles, types and sizes to accommodate households of all ages, sizes and incomes; compact and human-scale design; an interconnected street system with sidewalks, bikeways, and transit access; retain existing buildings with historical or architectural features that enhance the community's visual character; and preserve and incorporate significant environmental features.
11. 
MU-C Mixed-Use Community. The purpose of the MU-C District is to provide areas for the development and redevelopment of land based on the design principles of pedestrian-oriented mixed-use districts that integrate retail, services, entertainment, civic, institutional, residential, and small parks/plazas. This district is characterized by multistory buildings, higher development densities, buildings located close to streets and sidewalks, and site and building design that create vibrant and unique places within the community.
12. 
MC Medical Campus. The purpose of the MC District is to encourage and foster the planning, design and construction of well-functioning, attractive medical campus environments, and coordinate the master plans of these institutions with the City's plans, policies and zoning standards. It is intended, but not required, that multiple principal uses will be present on an overall campus facility without separate lots for each use.
13. 
I-1 Light Industrial. The purpose of the I-1 District is to provide areas for light industrial uses, such as the assembly, fabrication, and processing of goods and materials, provided that industrial activities are conducted entirely within buildings and where the by-products of industrial activities, such as noise, odors, smoke, and storage are confined entirely within the buildings and ordinarily do not have nuisance impacts on surrounding properties.
14. 
I-2 Heavy Industrial. The purpose of the I-2 District is to provide areas for heavy industrial uses, including the manufacturing, assembly, fabrication, processing, warehousing, distribution, and related operations that generally require larger land areas, significant exterior operation or storage of equipment and materials, and/or where the by-products of industrial activities, such as noise, odors, smoke and storage, may have nuisance impacts on surrounding properties.
15. 
P-1 Public and Semi-Public. The purpose of the P-1 District is to provide areas for a variety of public and semipublic institutional uses that offer important services needed by the community, including governmental, educational, social service, religious, and cultural.
16. 
P-2 Park and Open Space. The purpose of the P-2 District is to provide areas that reserve and protect land for recreational (active and passive), scenic and natural resource uses.
A. 
General.
1. 
Table 13.02.22-1: Principal Uses Table lists land uses and indicates whether they are permitted, permitted with standards, conditional, or prohibited. The table also includes references to whether additional use specific standards are applicable to that use. The following definitions shall be referenced when using Table 13.02.22-1:
a. 
Permitted uses. A "P" in a cell of the use table indicates that the land use is allowed by right in that base zoning district.
b. 
Permitted with standards uses. A "PS" in a cell of the use table indicates that the land use is allowed when standards identified in Chapter 02, Division 6, Use-Specific Standards, are met. Uses permitted with standards are also subject to all other applicable requirements of the UDC.
c. 
Conditional uses. A "C" in a cell of the use table indicates that the land use is allowed in the base zoning district only upon approval of a conditional use permit as described in Section 13.05.22 and in compliance with any use specific standards identified in Chapter 02, Division 6, Use-Specific Standards. Uses subject to a conditional use permit are also subject to all other applicable requirements in the UDC.
d. 
Prohibited uses. A blank cell in the use table indicates that the land use is prohibited in that base zoning district.
2. 
Table 13.02.22-2: Accessory Uses Table lists accessory uses and indicates whether they are permitted or permitted with standards, conditional, or prohibited. The table also includes references to whether additional use specific standards are applicable to that use. The following definitions shall be referenced when using Table 13.02.22-2:
a. 
Permitted uses. A "P" in a cell of the use table indicates that the accessory land use is allowed by right in that base zoning district.
b. 
Permitted with standards uses. A "PS" in a cell of the use table indicates that the accessory land use is allowed when standards identified in Chapter 02, Division 6, Use-Specific Standards, are met. Uses permitted with standards are also subject to all other applicable requirements of the UDC.
c. 
Conditional uses. A "C" in a cell of the use table indicates that the accessory land use is allowed in the base zoning district only upon approval of a conditional use permit as described in Section 13.05.22 and in compliance with any use specific standards identified in Chapter 02, Division 6, Use-Specific Standards. Uses subject to a conditional use permit are also subject to all other applicable requirements in the UDC.
d. 
Prohibited uses. A blank cell in the use table indicates that the accessory land use is prohibited in that base zoning district.
3. 
Unlisted uses. When a proposed land use is not explicitly listed in the use table, the Planning Department shall determine whether or not it is included in the definition of a listed use or is so consistent with the size, scale, operating characteristics, and external impacts of a listed use that it should be treated as the same use. Any such interpretation shall serve as a finding for future decisions of the City until the Zoning Administrator makes a different interpretation.
4. 
Uses for properties within overlay zoning districts. When a property is located within the boundaries of one or more overlay districts, the most flexible use provision among the overlay and base zoning districts shall apply.
