Environmental Services held the first council reading for Title 17.38 on Oct. 7 and second council reading on Oct. 14. The 2020 Stormwater Management Manual will be in effect later this fall.
Proposed 2020 SWMM
The proposed 2020 SWMM and changes to Title 17.38 are posted at www.portlandoregon.gov/bes/2020SWMM along with several guides summarizing the changes.
The SWMM includes requirements for stormwater management and applies to development activities that construct or alter impervious area. It applies to some paving projects in the right-of-way and any parcel-based development on properties. The SWMM also includes protections for drainageways on private property. Title 17.38 is the section of City code that authorizes the SWMM, the City’s Maintenance Inspection Program, and its Source Control Manual. These stormwater requirements enable the City to comply with regulatory requirements and to protect both watershed resources and infrastructure investments.
