Utility crews Thursday worked to repair 4 water main breaks in the Silver Lake and Mar Vista areas that left about 100 customers without service and caused a sinkhole in one neighborhood.

At 2:15 a.m., an 8-inch main break was reported in the 2400 block of Glendale Boulevard in the Silver Lake area, Los Angeles Department of Water and Power spokeswoman Gale Harris said.

At 3:15 a.m., a 4-inch main break was reported in the 3900 block of Moore Street in the Mar Vista area, the LADWP reported.

In the second break, some debris propelled by the high-pressure water damaged several nearby vehicles, an LADWP representative said.

A sinkhole several feet deep also developed around the broken pipe.

It was not immediately known when there would be complete water restoration to the affected areas.
