Work to strengthen Oroville Dam, shore up downstream levees and other types of flood-prevention projects would be eligible for fast-tracked state approval under new California legislation lawmakers will consider when they return from summer recess next month. The measure by state Sen. Jim Beall, D-San Jose, whose district suffered heavy flood damage in February, would require state agencies to speed up permit processing and approval for certain types of flood-control projects. Current law already allows authorities to exempt or delay permit requirements during emergencies. Yet other high-priority projects still have to go through the normal permitting process.
