We are responding to thousands of calls throughout the city and ask for your patience when contacting Police and Public Works during this busy time. Law enforcement and Public Works must prioritize how they respond to calls and complaints; they may not be able to respond to a report of a flooded roadway or clogged drained if there are more pressing emergencies taking place. Please note the City does not manage private property, and private property owners are responsible for maintaining their own property including clearing downed trees.
To report flooding, a clogged drain or a downed tree on public property - please call (650) 522-7300, if it is after hours call 650-522-7700.
Use this form to report and help document flooded roadways and clogged drains

- Avoid driving or being out on the roads between 3pm and 3am. If you must drive, NEVER DRIVE THROUGH A FLOODED ROAD
- If you have a storm drain outside your home, consider adopting it to help clear it of debris prior to the rain www.cityofsanmateo.org/adoptadrain
- Tend to your household. If you live near water (creek, lagoon, hillside etc), shore up your property. Secure outside furniture and garbage cans.
- Check on your neighbors. Whether they are elderly or new to California winter storms, checking on your neighbor, letting them know they are not alone
