I don't know how it will work out, but my personal experience in SD with mixed use so far is good. Where I live in San Diego (UTC) there was significant improvement due to mixed use (they are building high rises within walking distance of Westfield UTC mall, some of the new residential buildings also have office space inside them (looking at plans for Lux, yes, the name is cringy)). Where I work in San Diego (Carmel Valley) there is a large new development project (One Paseo) that is located next to a mall (Del Mar Highland Center) which is being significantly renovated, and One Paseo itself includes dense residential, office buildings, and restaurants/shops (in fact, the restaurants/shops are already opened while housing will take a few more years to be ready). Both of these developments involve building multistory parking garages to accommodate parking needs.
