tom fayram is in charge of clearing all this out. he says each of these rocks weighs up to five tons. the mudslide was so large it changed the elevation in some neighborhoods by as much as six feet. >> our main job is to race to open up every creek channel, get every bridge unplugged, because we will get rain, and so we have to be ready for it. >> reporter: the same massive cleanup effort is happening along highway 101, where trucks are hauling away thousands of pounds of debris every day. more than 20 million pounds have been dumped here at the ventura county fairgrounds. rocks, trees, plastics, and metals are sorted out, and then taken to either a recycling center or a landfill. the county is having to dump some cleaned mud at the beach. it's all a race against the clock until the next storm. >> it was just a little village in the forest, and it was beautiful. >> reporter: this is mary beth meyer's cottage before the mudslide. now this is all you see. she lost 12 of her 24 neighbors on her street. >> no one lived through that storm
