Meanwhile, other buildings were temporarily evacuated yesterday as walls cracked and beams groaned under the strain.

El Dorado County Fire Captain Mike Pott says another danger is propane tanks that may have been damaged by all the heavy snow. Pott says their urging residents to check their tanks.

"Just making sure that you haven't had a lot of snow drop out of trees or snow coming off steep roofs that have hit the propane tanks and maybe knocked it off their blocks or have actually bent the pipe or broken the pipe for the regulator and the underground piping that goes to the house. That can go undetected with several feet of snow over the tank you don't even realize it until you have an accumulation of propane and it finds an ignition source and then we have an explosion."

Over the weekend, a section of roof collapsed at the Knotty Pine Lanes bowling alley in Pollock Pines. Partial roof collapses also hit a logging business and a hardware store.

Several other businesses had snow scares; including an Umpqua Bank branch that was closed after workers heard cracking noises; a grocery store and a pharmacy that were temporarily closed; and a steakhouse where a ceiling sagged.
