In 2016, Environmental Services separated
Chapter 4 of the Stormwater Management Manual (SWMM) from the SWMM and elevated into its own Administrative Rule, the Source Control Manual (SCM). The new SCM and the SWMM are complementary manuals. Together, they make up a BES portfolio of administrative rules that provide goals and policies aimed at protecting the environment, city assets, and the public.
The SCM provides policy that governs drainage and discharges resulting from development and post-development activities or specific site uses and characteristics. The manual identifies structural, operational, and treatment best management practices designed to control specific types of sources of conventional and toxic pollutants in groundwater, stormwater, and wastewater.
The SCM is part of BES’ Administrative Rules, authorized by Portland City Code (PCC)
Chapters 3.13, 17.34, 17.38, and 17.39.
The City of Portland adopted the SCM, and it became effective on August 19, 2016. As of November 21, 2016, project designers must use the 2016 SCM, if applicable.
