Update from City Council on the Target location. Unless the developer requests a zoning change, the matter won't go before City Council. Currently the area for the proposed Target is zoned General Commercial, which is what the entire corridor just east of I-15 is zoned, from 2100 S to 200 S.

Council rep like my suggestions and was going to pass it on to planning and zoning. Unfortunately if the developer has already submitted the application there is no way to change the zoning at this point. It would simply be planning an zoning that is willing to give them higher densities or offer to rezone to mixed use to allow the developer to ad a housing component. If the developer wants to stick with the current plan then they simply have to meet the requirements currently set by the General Commercial Zone.
