A. District Purpose. The purpose of the Mixed Use-Residential (MU-R) district is to:
1. Implement the West Berkeley Plan Mixed Residential District designation;
2. Support the continued development of a mixed-use district which combines residential, live/work, light industrial, arts and crafts and other compatible uses;
3. Strengthen residential concentrations which exist within the district;
4. Provide appropriate locations for a broad range of live/work activities to occur;
5. Provide a transitional district between the Residential Districts to the east of the district and the Manufacturing Districts to the west of the district;
6. Encourage light manufacturers and wholesalers which are compatible with a mixed use-residential district;
7. Support the development of businesses of all types which contribute to the maintenance and improvement of the environment;
8. Protect residents from unreasonably detrimental effect of nonresidential uses, such as noise, vibration, odors, smoke, fumes, gases, dust, heat and glare, to the extent possible and reasonable within a mixed-use West Berkeley context;
9. To the extent feasible, protect industrial uses, particularly light industrial uses, from unreasonable intrusions on their ability to operate lawfully; and
10. Permit retail and food service activities which are either limited and small scale, primarily serving persons living and/or working in the district, but not a citywide or regional clientele, or which are ancillary and designed to maintain and enhance the economic viability of manufacturers in the district.
