OAKLAND -- Damage from major flooding at the Oakland school district headquarters last week might be more extensive than first thought.

A letter from Oakland school district spokesman Troy Flint, emailed Tuesday evening, said the "initial assessment phase" will last eight to 10 weeks.

"Although we're still in the early stages of gauging the damage, it's apparent now that staff who normally work at 1025 Second Avenue will be displaced through the spring," the letter said.

Two dozen departments, including the superintendent's office and accounts payable, will scattered among buildings throughout the district. For more information about the locations, visit www.ousd.k12.ca.us.
