Main Content

Clackamas Water Environment Services is updating its Sanitary and Stormwater Rules and Standards. The proposed Rules and Standards documents are available for public comment beginning March 17, 2021, and ending April 17, 2021.  
Revisions to the WES Sanitary and Stormwater Rules and Standards include the following:

  • Stormwater performance standards (retention, water quality, flow control), project thresholds, exemptions, and in-lieu fees
  •  Stormwater facility selection and design – facility types, allowable uses, prioritization, minimum design criteria, sanitary connections, pretreatment requirements and conveyance design standards
  • Sanitary and stormwater fiscal policies
  • Easements, maintenance, and use of public properties

WES' Rules and Standards Update Project was initiated to review existing rules and standards and recommend updates to reflect new technologies, approaches, and development patterns; address regulatory changes and requirements; and provide uniform and streamlined development review and approval processes.
