The Los Angeles Fire Department, which drew praise for containing the blaze, said it was caused by power lines that had fallen behind residences. The DWP, however, said it was working to determine the facts. Utility spokeswoman Gale Harris said the DWP was investigating whether it owned the land. More than 246,000 DWP and Southern California Edison customers lost power at times after the winds hit. About 1,900 SoCal Edison customers remained out at its last update late Friday. The DWP said it could take up to two more days for power to be restored to everyone. Councilman Dennis Zine asked that the DWP and other city departments with land in mountainous areas determine within days whether any brush needs cutting “because of the weather change.” About 20,000 customers of the city’s Department of Water and Power remained without electricity for a third day early Saturday as crews labored to repair toppled utility poles and snapped power lines. The municipal utility also is investigating whether a blown power line in overgrown land it owns sparked a Thursday wildfire that damaged three expensive Beverly Hills homes. In a statement, the DWP said that if it is found to have responsibility “we will own up to it.” The DWP, one of the largest property owners in the city, said it had already begun expediting brush-clearing because of extraordinarily dry weather and “will immediately conduct further assessment of all our properties to determine whether additional brush clearance is needed.” 160Want local news?Sign up for the Localist and stay informed Something went wrong.
