A. 
The purpose of this chapter is to provide standards for nonresidential development and mixed-use development in commercial zones that promote quality development and enhance the livability, walkability, and safety of the community. Standards prioritize more dense and walkable development, in order to enhance climate resilience and economic activity with the limited developable land available in the city.
(Ord. 18-28 §1; Ord. No. 24-05, 4/23/2024)

B. 
Residential development, except for mixed-use development, in commercial zones is subject to the approval processes and standards of the applicable housing type in Part 18.200, Residential Development Standards.
