What are the richest cities in California?

I know I live in a rich city in CA. I live near San Jose, but not in it. What are like the the top 20, maybe? It doesn't have to be in order. OR what do you think are the richest cities in California (particulary, northern CA)? Thanks

1. Los Angelos, Hollywood, Malibu...
2. Beverly Hills/West Hollywood/Brentwood...probably the entire westside area of Los Angeles!
3. hmm lets see i think most of the richest cities are down south. for example starting off with newport beach, coto de caza, ladera ranch, laguana beach. those are the top in southern cali. northern would be in the hollywood hills, beverly hills.
