City is updating Erosion and Sediment Control Manual

The Bureau of Environmental Services (BES) together with the Bureau of Development Services (BDS) are updating the City of Portland's Erosion and Sediment Control Manual. As part of the update process, the bureaus developed a short survey to gather input from the community. The survey is now closed.


Why does erosion control matter?

Construction site erosion is a significant source of sediment and other pollutants. Erosion from construction sites without proper installation and maintenance of erosion and sediment control best management practices can:

  • Negatively impact the water quality in rivers and streams
  • Endanger fish, wildlife, and their habitats
  • Cause damage to wetlands, private property, and public infrastructure.

Why update the Erosion and Sediment Control Manual?

State and federal regulations under the Clean Water Act require the City to implement an erosion control program with enforceable regulatory mechanisms to prevent the transport of construction-related sediment and pollutants to state rivers and streams. The City of Portland adopted erosion control code Title 10 and the Erosion and Sediment Control Manual to comply with the requirements to protect human health, the environment, and city infrastructure. The current manual has not been updated since 2008, and an update has been identified as a priority project to comply with state and federal regulations in a way that is clear, enforceable, and technically up-to-date.
