Two giant sinkholes formed in separate Bay Area communities during the heavy rain from a powerful storm that passed through the Bay Area over the weekend.
In one instance, a giant sinkhole swallowed two lanes of a street in a residential neighborhood in Lafayette Sunday.
High water levels and a clogged storm drain in Lafayette Creek destroyed a portion of Mountain View Drive Sunday, creating a sinkhole where the road once was, Lafayette City Manager Steven Falk said.
Erosion of the road accelerated when the heavy current of the creek clogged the storm drain with large debris, including branches and a bureau, some time between 7:30 a.m. and 9 a.m., Falk said.
Water began to run over the top of the road, forcing its closure soon after. Around 3 p.m. Sunday, the road collapsed onto the storm drain and left a hole 80 feet long, 40 feet wide, and 15 feet deep, Falk said.
