Hundreds of volunteers across Oakland have adopted storm drains to help their neighborhoods prepare for rainstorms. It doesn't take much to keep a storm drain clear. A little volunteer effort goes a long way in helping Public Works maintain over 13,000 storm drains to reduce flooding and prevent pollution of our waterways. When you sign up to Adopt a Drain, you become eligible to borrow City tools and supplies, and you will receive the City's rain alert notifications.
