There are two places that are a close commute to Chatsworth that are good for raising families. Simi Vally/ Moorpark and Santa Clarita. Both areas are known to be family friendly and have good schools. In my opinion they both are better, safe communities, and a great alternative to living in San Fernando Valley.
I am familiar with both if you would like to set up a time I can show you both areas and discuss what they have to offer.
