Link to spring bill insert about stormwater runoffWhat is stormwater runoff?

Portland receives an average of 37 inches of rain a year.

In a natural environment, soil and plants absorb rain. However, when streets, buildings, and parking lots cover the ground, rain can wash over the hard surfaces to create stormwater runoff. When runoff is not managed properly, it can:

  • Carry dirt, oil and other pollutants to rivers and streams.
  • Cause erosion and flooding.
  • Harm property and wildlife habitat.
  • Reduce capacity of sewer pipes to carry sanitary sewage, causing backups into streets and basements.

Learn more about what the City is doing about stormwater runoff and what you can do.
