Division II

DISTRICT REGULATIONS

§ 18.04.010 Purpose.

A. 
The purpose of residential districts is to:
1. 
Provide for a full range of housing types to meet the diverse economic and social needs of residents;
2. 
Preserve, protect, and enhance the character of the City's neighborhoods;
3. 
Enhance the quality of life of residents;
4. 
Ensure that the scale and design of new development and alterations to existing development are compatible with surrounding uses and appropriate to the physical and aesthetic characteristics of the proposed location; and
5. 
Provide sites for public and semi-public uses such as parks, schools, and other community uses that serve residents and complement surrounding residential development.
B. 
Additional Purposes of Each Residential District.
1. 
Residential Low Density (RL). The RL district is intended to provide for residential development and other compatible uses in a low density residential neighborhood setting at densities up to nine (9) dwelling units per acre. Housing types in this district are primarily single-unit detached units, but other types are allowed subject to density limitations. The RL district implements the Low Density Residential General Plan land use designation.
2. 
Residential Medium Density (RM). The RM district is intended to provide for a variety of housing types at densities from ten (10) to twenty-two (22) dwelling units per acre. Housing types in this district include single-unit detached units, townhomes, garden homes, zero lot line homes, apartments and condominiums. Other compatible uses appropriate in a medium density residential environment are allowed. The RM district implements the Medium Residential Density General Plan land use designation.
(Ord. 24-002 § 5 (Exh. A))

§ 18.04.020 Land use regulations.

Table 18.04.020: Land Use Regulations – Residential Districts, sets the land use regulations for the residential districts. Land uses are defined in Chapter 18.34 DMC, Use Classifications. Land uses not listed in the table and not substantially similar to the uses listed are prohibited. In cases where a specific land use or activity is not defined, the Community Development Director shall assign the land use or activity to a classification that is substantially similar in character. The decision of the Director in such instances may be appealed under DMC § 18.21.120, Appeals. The Director may refer any request for determination of use classification that is unclear, may generate substantial public controversy, or involve significant land use policy decisions to the Planning Commission for decision.

§ 18.05.010 Purpose.

A. 
The purpose of the commercial and mixed-use zoning districts is to:
1. 
Provide for the orderly, well-planned, and balanced development of commercial and mixed-use zoning districts;
2. 
Designate adequate land for a full range of local- and regional-serving commercial and retail services, consistent with the General Plan;
3. 
Maintain and strengthen the City's economic resources;
4. 
Increase employment opportunities and expand the economic base of the City;
5. 
Provide appropriately located commercial areas that provide a variety of goods and services for residents, employees, and visitors;
6. 
Provide opportunities for a mix of complementary uses that may combine residential and nonresidential uses, or a variety of nonresidential uses, on the same site; and
7. 
Promote pedestrian-oriented, mixed-use areas at appropriate locations.
B. 
Additional Purposes of Each Commercial and Mixed-Use District.
1. 
Downtown Mixed-Use (DMX). The DMX district is intended to promote downtown Dixon as a vibrant and attractive commercial and entertainment destination for residents and visitors to the community. Compatible uses include those with complementary services and hours of operation that encourage patronage of multiple establishments in a single visit. Community assembly uses are limited to address compatibility with an active nightlife atmosphere and to support the downtown as a commercial and entertainment center. A range of retail, employment, residential, entertainment, cultural, civic, and personal service uses that provide commercial services are allowed in single- or mixed-use development configurations. Active uses are required on the ground floor along primary corridors. Residential densities up to thirty (30) units per acre are allowed. The DMX district implements the Downtown Mixed-Use General Plan land use designation.
2. 
Corridor Mixed-Use (CMX). The CMX district is intended to provide areas for a mix of retail and commercial uses, supported by housing, along the City's major corridors. Mixed-use can be vertical and/or horizontal, and the allowable range of uses includes large format retail, shopping centers, offices, hotels and housing. Residential densities from twelve (12) to twenty-eight (28) dwelling units per acre are allowed. On larger sites, more than one (1) use is required. On smaller sites, a single use may be permitted. The CMX district implements the Corridor Mixed-Use General Plan land use designation.
3. 
Campus Mixed-Use (CAMX). The CAMX district is intended to foster new mixed-use employment districts with a range of employment-generating development as the primary use, with easy access to the regional transportation network. Residential development shall be permitted as a secondary use. The CAMX district would promote clusters of light industrial, manufacturing, office, research and development, retail, hotel, and services as primary uses on parcels near or adjacent to I-80 and SR-113 at gateways to the City. Industrial and commercial developments without housing are permitted. Mixed-use development can be integrated vertically or horizontally within a development plan. Housing shall consist of apartments, townhomes, or condominiums, be integrated with nearby nonresidential uses, and encompass no more than forty percent (40%) of the project site or forty percent (40%) of the total project FAR. The minimum required residential density shall be fifteen (15) dwelling units per acre and the maximum residential density is thirty (30) dwelling units per acre. The CAMX district implements the Campus Mixed-Use General Plan land use designation.
4. 
Neighborhood Commercial (CN). The CN district is intended to provide for shopping centers with off-street parking or a cluster of street-front stores that serve the immediate neighborhood. The CN district implements the Neighborhood Commercial General Plan land use designation.
5. 
Regional Commercial (CR). The CR district is intended to provide for a full range of commercial land uses that cater to traffic passing through Dixon on I-80 as well as to local residents. The CR district implements the Regional Commercial General Plan land use designation.
6. 
Service Commercial (CS). The CS district is intended to provide for retail and service uses not typically located in shopping centers, including auto repair, storage facilities, equipment rental, wholesale businesses, nurseries, and contractors' facilities. The CS district implements the Service Commercial General Plan land use designation.

In the CMX district, a minimum of one (1) residential use and a minimum of one (1) commercial use are required on any development site two and one-half (2.5) acres or more in size (see subsection A of this section, CMX Zoning District, Additional Use Regulations).
Land uses are defined in Chapter 18.34 DMC, Use Classifications. Land uses not listed in the table and not substantially similar to the uses listed are prohibited. In cases where a specific land use or activity is not defined, the Community Development Director shall assign the land use or activity to a classification that is substantially similar in character. The decision of the Director in such instances may be appealed under DMC § 18.21.120, Appeals. The Director may refer any request for determination of use classification that is unclear, may generate substantial public controversy, or involve significant land use policy decisions to the Planning Commission for decision.

§ 18.06.010 Purpose.

A. 
The purpose of industrial zoning districts is to:
1. 
Provide appropriate areas of the City where industrial uses can locate and operate without significant conflicts with other land uses;
2. 
Strengthen the City's economic base and provide employment opportunities for residents of the City; and
3. 
Provide areas for a wide range of manufacturing, industrial processing, and service commercial uses and protect areas where such uses now exist.
B. 
Additional Purposes of Each Industrial Zoning District.
1. 
Light Industrial (IL). The IL district is intended to provide areas for small-scale industrial businesses and operations that do not create adverse visual, noise, or other impacts on adjoining public and residential properties. This district allows for small-scale industrial, manufacturing, and service uses. Industries that use or produce substantial amounts of hazardous materials or generate noise, odor, or other pollutants are not permitted. This district implements the Industrial General Plan land use designation.
2. 
General Industrial (IG). The IG district is intended to provide areas for businesses that have potential to create adverse visual, noise, or other impacts to adjoining public and residential properties. This district allows for large- and small-scale industrial, manufacturing, heavy commercial uses such as food processing, fabricating, motor vehicle service and repair, truck yards and terminals, warehousing, distribution and storage uses without a tax revenue generating component, wholesale uses, construction supplies, building material facilities, offices, contractors' yards and the like. This district implements the Industrial General Plan land use designation.
(Ord. 24-002 § 5 (Exh. A))

§ 18.06.020 Land use regulations.

Table 18.06.020: Land Use Regulations – Industrial Districts, sets the land use regulations for the industrial districts. Land uses are defined in Chapter 18.34 DMC, Use Classifications. Land uses not listed in the table and not substantially similar to the uses listed are prohibited. In cases where a specific land use or activity is not defined, the Community Development Director shall assign the land use or activity to a classification that is substantially similar in character. The decision of the Director in such instances may be appealed under DMC § 18.21.120, Appeals. The Director may refer any request for determination of use classification that is unclear, may generate substantial public controversy, or involve significant land use policy decisions to the Planning Commission for decision.

Any permitted or conditional use authorized by this code may be included in an approved PD plan consistent with the General Plan land use designation for the property.
(Ord. 24-002 § 5 (Exh. A))

§ 18.09.040 Development standards.

A. 
Minimum Area. The minimum area of a PD overlay district shall be five (5) acres; however, the City Council may approve a smaller area if it finds that a PD would provide greater benefits to the general welfare of the City residents and property owners than development under conventional zoning because of unique characteristics of the site or the proposed use.
B. 
Residential Unit Density. Except where a density bonus is granted in compliance with Chapter 18.12 DMC, Affordable Housing Density Bonus, the total number of dwelling units in a PD overlay district shall not exceed the maximum number permitted by the General Plan density for the total area of the planned development.
C. 
Floor Area Ratio (FAR). The FAR based on the total floor area in a PD overlay district shall not exceed the maximum FAR permitted by the General Plan for the total area of the planned development.
D. 
Performance Standards. The performance standards prescribed by Chapter 18.17 DMC, Performance Standards, apply.
