A. 
Purpose. A City goal is to strengthen certain established residential areas having frontage on State highways as transition areas between commercial centers and outlying residential areas. The district is intended to support this goal through elements of design and appropriate mixed-use development. Mixed-use development features design standards that allow residential and commercial uses to occur simultaneously on the same lot. This chapter provides standards for the orderly improvement of mixed-use commercial areas based on the following policies:
1. 
Use land and urban services efficiently;
2. 
Support a mixture of land uses to encourage walking as an alternative to driving, and provide more employment and housing options; and
3. 
Allow certain commercial uses amongst existing residential uses that are compatible with, and add interest to, the established residential character of the area.
B. 
The Commercial Mixed-Use District applies to the following area: those properties bounded by 4th and 9th Streets along S. Main Avenue (Fort Stevens Highway/State Highway 104) extending west to, and including, the easterly half of the old railroad right-of-way and extending east to the Skipanon River's A-2 (Aquatic Conservation) Zoning District.
