CHAPTER 170
MIXED USE ZONING DISTRICTS
170.01 APPLICAITON
The restrictions, regulations, standards and guidelines in this Chapter for land use and development shall apply to the following zoning districts within the City:
| MU-1 | Neighborhood Mixed Use District |
| MU-2 | Community Mixed Use District |
Effective on: 5/1/2023
170.02 DISTRICT INTENTS
The following statements specify the intents of the zoning districts established to regulate areas of the City considered appropriate for a mix of uses:
- 1.Neighborhood Mixed Use District. The intent of the MU-1 district is to facilitate development or redevelopment of smaller, pedestrian-oriented nodes that include a mixture of medium density housing types such as two- to four-unit structures, townhomes, and small apartments and neighborhood-scale retail, offices, and services which primarily serve adjacent neighborhoods. Residential uses should make up a majority of the land use mix in the NMU district.
- 2.Community Mixed Use District. The intent of the MU-2 district is to foster mixed-use development or redevelopment of larger nodes characterized by pedestrian-oriented design and sensitive transitions to adjacent residential neighborhoods. A mixture of uses, including community-scale retail, offices, and services and a variety of higher density housing types such as townhomes and apartments and are appropriate within this district. Community-scale commercial uses should make up a majority of the land use mix.
Effective on: 5/1/2023
