Following is a Neighborhood Watch email I sent about 4PM:
A water main has broken near the top of Oak Valley Drive - break probably occurred around 320PM on Saturday, December 29, 2012.
CS Fire Department has blocked the street, a good section of the road is about to collapse.
Utilities is sending a crew to search for the turn off value. Then Utilities will find the break, dig up the area, and fix it. Utilities said to expect the water to be off "for several hours." I expect it will be 24 hours or longer.
Only thing I can suggest is to fill pots and pans with potable water and the bathtub and buckets to flush toilets.
