Gov. Jerry Brown is asking for federal assistance to repair damage at Oroville Dam and other infrastructure impacted by February storms that caused flooding, mudslides and power outages. Sunday’s request follows three other petitions for federal help that President Donald Trump’s administration has granted to assist with earlier storm damages and the emergency at Oroville Dam. Brown’s office says the governor also declared a state of emergency for Contra Costa and Solano counties, bringing the total to 50 counties affected by February storms.
