Stormwater Resources

Under the Joint Source Control Strategy, DEQ is responsible for addressing upland sources that are impacting or may potentially impact the Willamette River in the Portland Harbor area. Stormwater is one of the pathways by which contaminants from upland sites could reach the river. DEQ works with Cleanup sites in Portland Harbor, as well as public agencies with oversight over municipal stormwater outfalls (City of Portland, Port of Portland and Oregon Department of Transportation) to evaluate stormwater discharges and implement source control measures if necessary. The following resources are designed to support those efforts.

Best management practices and other resources

  • Catch Basins Fact Sheet
    Catch basin design, effectiveness and sediment sampling.
  • Environmentally Responsible Best Management Practices
    Basic maintenance practices for stormwater catch basins.
  • International Stormwater Best Management Practices Database
    Technical documents, software and database aimed at providing scientifically sound information to improve the design, selection and performance of BMPs. The project, which began in 1996 under a cooperative agreement between the American Society of Civil Engineers and the U.S. Environmental Protection Agency, has support and funding from a broad coalition of partners including the Water Environment Research Foundation, ASCE Environmental and Water Resources Institute, USEPA, Federal Highway Administration and the American Public Works Association.
