A mysterious water leak in Chula Vista has residents wondering who is to blame. Homeowners in the Robinhood Point community say water has been leaking down a nearby hillside for several years. "We were concerned that the source of that water may be a couple of water tanks that are built on the top of this hill owned by the Otay Water District," said Dave Sommers, who has lived in the area since 1997. Sommers says neighbors first noticed the water about five or six years ago as it seeped onto the roadway and into people's backyards.
