The 500 West Medium Density Mixed-Use Project Redevelopment Option (PRO-A-38) zone is a residential/professional office mixed-use development zone. The standards set forth herein are intended to encourage desirable infill development on certain portions of land along 500 West. It is intended to provide for sites with existing development to be enhanced through the allowance for additional, appropriate, and compatible development to occur without requiring the complete redevelopment of a site.
