While work crews used bulldozers, residents used shovels, buckets and hoses on Saturday to clean up the muck left in a Camarillo neighborhood from a mudslide triggered by a Halloween rainstorm.
Some 20 residents were evacuated Friday night mud flowed along San Como Lane.
The mud damaged at least one home that had to be red-tagged and left a husband-and-wife trapped inside.
"You could hear, 'Help! Help! Oh, help me!" said Dorothy Rosenfeld, of the female voice coming from across the street.
The woman was stuck in two-feet of mud. Rosenfeld's son helped her out, but the husband remained trapped. The couple's dog is unaccounted for.
Firefighters used a chain saw to remove the door to free the man, said Tom Kruschke, a spokesman with the Ventura County Fire Department. The man refused medical treatment.
Geologists determined the cause was due to a clogged storm drain.
Most of the mud came from hills denuded by the 2013 Springs Fire, sparked by an accidental ignition from passing vehicle off a freeway embankment. The blaze scorched more than 24,000 acres.
