The owners of six damaged homes said they need help from the government.
The Lake County Board of Supervisors asked Gov. Jerry Brown to declare an emergency so funding might be available to stabilize utilities and determine the cause of the collapse. On May 6, state Sen. Noreen Evans, D-Santa Rosa, wrote a letter of support asking Brown for immediate action. The California Emergency Management Agency said Brown was still assessing the situation.
On Wednesday, the state sent a water resources engineer and a geologist to look at the problem. Sen. Dianne Feinstein sent a representative the next day.
Lake County, with farms, wineries and several Indian casinos, was shaped by earthquake fault movement and volcanic explosions that helped create the Coast Ranges of California. Clear Lake, popular for boating and fishing, is the largest fresh water lake wholly located in the state.
It is not unusual for groundwater in the region to make its way to the surface then subside. Many natural hot springs and geysers receded underground in the early 1900s and have since been tapped for geothermal power.
Homeowners now wonder whether fissures have opened below their hilltop, allowing water to seep to the surface. But they're so perplexed they also talk about the land being haunted and are considering asking the local Native American tribe if the hilltop was an ancient graveyard.
"Someone said it must be hexed," said Blanka Doren, a 72-year-old German immigrant who poured her life savings into the house she bought in 1999 so she could live on the rental income.
The home shares a wall with her neighbor, Jagtar Singh — who had two days of notice to move his wife, 4-year-old daughter and his parents before the hill behind the back of his home collapsed — taking the underside of his house and leaving the carpet dangling.
Doren is afraid that as Singh's house falls it will take hers with it. Already cracks have spread across her floors.
Damaged houses in the subdivision have been tagged for mandatory removal, but the hillside is so unstable it can't support the heavy equipment necessary to perform the job.
"This was our first home," said Singh, who noticed a problem in April when he could see light between the wall and floor of his bedroom. A geotechnical company offered no solutions.
"We didn't know it would be that major, but in one week we were gone," he said.
So far insurance companies have left the owners of the homes — valued between $200,000 and $250,000, or twice the median price in the county — dangling too. Subsidence is not covered, homeowners said. So until someone figures out whether something else is going on, they'll be in limbo.
"It's a tragedy, really," contractor Dean Pick said as he took photos for an insurance company. "I've never seen anything like it. At least that didn't have the Pacific Ocean eating away at it."
