That would appear to be about 4 levels deep. It all starts with the name of a tract - Stoney Point. Then I address the area - Bridgeport. After that, I hit the city - Valencia CA (not to be confused with spain...) I then move to the over-all area - Santa Clarita Valley, which consists of 6 cities - Castaic, Canyon Country, Newhall, Saugus, Stevenson Ranch and Valencia.
Whew - it is enough to give a person severe brain "lock".
Below on the map you will see a "polygon" search that was built by myself and my Santa Clarita Real Estate team.
