I am working on a mixed use project. It consists of 36,000 sf of commercial and 22 dwelling units. There is a great deal of opposition to the amount of density (mostly over fear of apartments). The opponents managed to sway the Planning Commission to recommend 12 units. Staff supports the 22. My question is - it would be helpful to point to some case studies or formulas that show how much density is required to make mixed use work. Any ideas?
