The business-residential zones are mixed use zones which will serve as a transition zone between residential zones and nonresidential zones. Many of the structures in these zones are used as single family homes or currently in office use. These zones, to the extent possible, should retain a residential character and be of sufficient lot frontage to minimize the visual and traffic impact on the adjacent roadway. Curb cuts should be minimized to alleviate traffic congestion through combining access for adjacent lots whenever possible. This zone is appropriate for offices, service uses and single-family dwellings. No retail or wholesale sale of goods is allowed in these zones.
