Additional purposes of each Commercial and Mixed Use District:

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 30 units per acre are allowed. The DMX District implements the Downtown Mixed Use General Plan Land Use Designation.

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 12 to 28 dwelling units per acre are allowed. On larger sites, more than one 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.

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 non-residential uses, and encompass no more than 40 percent of the project site or 40 percent of the total project FAR. The minimum required residential density shall be 15 dwelling units per acre and the maximum residential density is 30 dwelling units per acre. The CAMX District implements the Campus Mixed Use General Plan Land Use Designation.

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.

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.

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.
