The general point about suburbs, since their beginnings in the 1930s, has been their dormitory status. Town planners seem to have this idea that you should section cities off into residential, shopping, factory and office areas. This has always seemed silly to me; chaos has always seemed a better option as far as I could see. So you allow people to build for whatever kind of use they see the need for, wherever they think they see the need. In this framework, town planning becomes more an aesthetic issue than an organisational issue; and this seems to be what Cerritos has gone for. And there's no doubt that aesthetics do influence property prices.
Whether it works or not, of course you can't tell unless you live there.

Well, once upon a time, separating at least industrial uses from residential made a good amount of sense in preserving residential property values and mitigating the negative environmental and health impacts of traditional industry. Now that the West is in a post-industrial age that really isn't necessary anymore, and among US planners the concept that uses must be segregated is rapidly ending. California urban planners are the US leaders in "mixed-use" planning and, as you guessed, treating zoning and planning as more aesthetic tools.
