2016 Source Control Manual

2020 Source Control Manual Now in Effect

The City of Portland 2020 Source Control Manual (SCM) became effective Dec. 14, 2020. Beginning Dec. 14, 2020 and until Mar. 14, 2021, project designers may choose to design their projects using either the 2016 SCM or the 2020 SCM. Starting Mar. 15, 2021, all projects must meet the requirements of the 2020 SCM.

Photo of cover of the Source Control ManualIn 2016, Environmental Services separated Chapter 4 of the Stormwater Management Manual (SWMM) from the SWMM and elevated into its own Administrative Rule, the 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.
