Creek blockages
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 on the Water District’s Watershed Hotline: 408-630-2378
You can also report creek issues on Access Valley Water, the district’s 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.
