Several Hollywood Hills streets closed by a torrent of mud and debris unleashed by water pouring from a fire hydrant possibly struck and sheared by a vehicle were open Thursday, authorities said.
The surge of water — initially thought to be caused by a water main break — was reported about 12:30 a.m. Wednesday in the 8400 block of Grandview Drive, according to the Los Angeles Department of Water and Power.
The hydrant was fed by a 12-inch main and “considerable water flow resulted,” according to a DWP statement.
The gushing water undermined part of a hillside sloping to Sunset Boulevard and sent the mud onto a number of streets, including Hillside and Franklin avenues and Kings and Queens roads, according to the Los Angeles Fire Department.
The DWP reported Wednesday night that its crews viewed private surveillance video which showed the hydrant was hit and sheared by a vehicle. This afternoon, a department spokeswoman said the cause of the hydrant’s failure is still under investigation.
Crews eventually shut off the spill and began work on repairs and debris removal.
The closed roads were reopened late Wednesday.
Water service to customers was not interrupted, according to the LADWP.
