The Orange County Fire Authority was called to the Rancho Alisal Apartments at 13800 Parkcenter Lane (map) about 10:15 a.m., according to spokesman fire Capt. Steve Concialdi.

An urban search and rescue team was among the firefighters who responded to flooding from the break in a large water main.
