The area you described is Lake Balboa city( W of 405 and S of Saticoy, N of Victory), . It is a nice smaller community. There is a link on the boundaries of LB: http://lakebalboanc.org/about-us/boundaries/.
I think, it is nice and relatively safe. Most of houses are owner occupied. The best part about this location: parks. What other city offers this much park ground?! Golf fields, tennis, biking and running trails, nice lake, Japanese Gardens, etc, etc, etc. Lake Balboa is a hidden gem of Valley:)
