LAFAYETTE -- A portion of road that collapsed under the siege of weekend storms likely will not be repaired for several months, a city official said Monday.
Heavy stormwater flow ruptured a water pipe and caused a portion of Mountain View Drive, between Crescent Drive and Brook Street, to sink Sunday morning, leaving a gap 80 feet long, 40 feet wide and 15 feet deep, Lafayette City Manager Steven Falk said.
Crews worked to prevent any more damage to water pipes and gas lines that run under the road, Falk said. They also are trying to drain standing water that could further erode the road.
"The priority (Sunday) was to stabilize the water pipes and gas lines, and we did that," Falk said. "The next priority now is to implement a temporary drainage system."
Repair work to the sinkhole continued Monday morning and is expected to be ongoing, Falk said. The road is expected to be closed through the winter, he said.
Nobody was walking on the road when it sank away and no injuries were reported.
Residents near the sinkhole can take alternate routes and have access to Mount Diablo Boulevard, the main road that runs through the downtown area, Falk said.
"We were fortunate, too, in that no private properties were damaged," he added.
Falk said that it appears stormwater ruptured an East Bay Municipal Utility District pipeline that was 12 inches in diameter and the break eroded and undermined the road.
