28. - COMMERCIAL ZONE
The purpose of the Commercial Zone is to provide an appropriate design to reflect the degree to which commercial development impacts other adjacent uses. The Commercial Zone has been divided into three classifications to promote versatility in development. The three zone areas are as follows:
A.
C-1, Commercial City Center.
i.
The Commercial City Center Zone is established to provide locations for a full range of office, retail commercial, mixed use and service uses which are oriented to serve the City as a whole. A variety of activities are encouraged, especially those which promote both daytime and night-time consumer activity.
ii.
The Commercial City Center Zone includes uses usually associated with a central business district, shopping facilities and mixed-use multi-family residential uses oriented to pedestrian traffic, as well as vehicular traffic. Site selection development and uses for Commercial City Center Zones shall take into account potential impacts on surrounding residential uses and measures shall be taken to minimize these impacts.
iii.
In order to stabilize, improve and protect the City's commercial areas, standards are established to ensure a quality urban environment with landscaping, light and air at street level, well-defined urban spaces, and compatibility of building materials, colors and textures.
B.
C-2, Commercial Transitional.
i.
The Commercial Transitional Zone is established to provide suitable locations for retail, big box retail, service and indoor recreational uses. These areas should serve as transition zones between Commercial City Center and Commercial Heavy Zones and should be located on arterial streets.
ii.
The C-2 Zone serves as the location for light to medium type of commercial activities allowed in the City. For this reason, these zones may be next to residential areas with an appropriate landscaped buffer.
C.
I, Commercial Heavy/Light Industrial.
i.
The I Zone is established to provide locations for the heaviest type of permitted commercial uses such as wholesale, light manufacturing, lumber or storage yards and outdoor recreation. For this reason, these zones should not occur next to residential areas so that the appearance from the highway or freeway does not present a poor image of the city.
ii.
This includes the production, processing, cleaning, testing and distribution of material goods and services.
iii.
Uses that will not be considered a nuisance by means of excessive smoke, noise, traffic, fumes, odors or other type of nuisance beyond that of the surrounding developments.
The following schedule indicates by the symbol "P" are the uses that shall be permitted in each Commercial Zone, and by the symbol "S," are the uses which require a Special Use Permit in accordance with the provision. Any use not identified within this schedule may be allowed through a Special Use Permit. The symbol "X" means that the use is not allowed.
(Ord. No. 12-2025, § 1(19.28.020), 12-2-2025)
