Report creek blockages and local street flooding

Content

Creek blockages

Keep creeks clean and flowing.  Trash and debris in creeks can block the flow of water and cause flooding. Help us keep creeks flowing by reporting downed trees, blockages or illegal dumping.

Report issues in creeks to Valley Water’s Watershed Hotline: 408-630-2378

You can also report creek issues on Access Valley Water, our online customer service portal

Local street flooding

Yard waste, leaves and soil can also obstruct storm drains and prevent stormwater from being properly drained, causing local street flooding. Cities maintain storm drain systems including gutters, drains and pipes in the street. To report a spill, dumping or blockage in storm drains, contact your city public works department according to the list below. For information on flood risks, interpreting FEMA flood maps, flood insurance or elevation certificates, contact your city's floodplain manager.
