Administrative Rule Adopted by Bureau of Environmental Services Pursuant to Rule-Making Authority
The text of the entire 2014 Stormwater Management Manual
is available on the Bureau of Environmental Services' website. What follows is an excerpt from the Introduction to the manual:
This Stormwater Management Manual (SWMM) is a technical document that outlines the City of Portland’s stormwater management requirements. The requirements defined in this manual apply to all development and redevelopment projects within the City of Portland on both private and public property and the right-of-way.
The City of Portland’s approach to stormwater management emphasizes the use of vegetated surface facilities to treat and infiltrate stormwater on the property where the stormwater runoff is created. Infiltrating stormwater onsite with vegetated surface facilities is a multi-objective strategy that provides a number of benefits, including but not limited to pollution reduction, volume and peak flow reduction, and groundwater recharge. These benefits play a critical role in protecting stormwater infrastructure and improving watershed health.
