Coastal areas are becoming more and more walkable... Minus the lack of density - Santa Monica is the prime example, ask people about walkability and everyone is excited, then talk about making it happen for more people and you get crucified.
In the valleys, walkability runs into the heat problems in the summer. Walking in 100F+ is no fun and can be dangerous to some.
There definitely is a very strong desire still for wider spaces, bigger yards, etc. As the result, walking in most of inland sprawl take a lot more time and effort.
