CMU-H
ST ROSE
Core Mixed Use - Historic Combining District
The CMU zoning district is applied to areas within downtown Santa Rosa to foster a mix of residential and nonresidential uses to activate the greater Old Courthouse Square area and key transit corridors. The principal objectives of the CMU designation are to strengthen the role of this area as a business, governmental, retail, tourism, entertainment, and cultural hub for the region, and to accommodate significant new residential development. New residential development will serve as a catalyst for increased activity and create a built-in market for retail, service, and entertainment uses. High-rise development in all residential or mixed-use buildings is envisioned in a walkable, bikeable environment with public gathering places such as plazas, courtyards, or parks and easy access to public transit. The H combining district is intended to recognize, preserve, and enhance Santa Rosa's locally designated historic resources.
