Additional Flooding Resources:

Public Works prepares our community in many ways, including:

  • We clean catch basins of debris every storm season
  • We maintain 33 “trash racks" (large grates that catch debris and keep our pipes that channel storm water from clogging)
  • During the rainy season, we lower the water levels of the Marina Lagoon
  • During the rainy season, our crews use leaf machines to clear storm drains, gutters, and streets
  • Prior to storm season, the City clears several of the canals, creeks, and storm culverts (water ways) with the worst levels of debris
  • We monitor areas with a history of flooding for storm conditions. Read more about these flood-venerable areas that are part of the FEMA Flood Zone.

Emergency Preparedness Resources:

San Mateo Consolidated Fire's Office of Emergency Services maintains a robust list of resources for your own emergency planning. Preparing before an emergency can make a big difference when you have little time to spare.
