Craig Davis's long quest to quake-proof the city's water system began at the epicenter of the 1994 Northridge earthquake. He experienced the early morning 6.8 magnitude shaker like most Angelenos did--in bed.
"The ground moved out from underneath me. When I fell, I landed on the floor, and the bed actually came back and hit me," Davis said. He was living in Santa Clarita at the time, and working in the geotechnical engineering division of the Los Angeles Department of Water and Power.
