The City of Portland’s Bureau of Environmental Services updates its Stormwater Management Manual (SWMM) every few years. You’ve received this message because you’ve been identified as someone who may be interested in reviewing and commenting on the updates proposed for 2020.
Along with the SWMM, BES is also updating Title 17.38, the code that provides the authority for the SWMM, the Maintenance Inspection Program (MIP), and the Source Control Manual (SCM).
The SWMM applies to development that constructs or alters impervious area including:
Certain paving projects in the public right-of-way
Parcel-based development on public and private properties
The SWMM also applies to properties that have drainageways.
NEXT STEPS
The SWMM draft and proposed code will be available for public comment beginning May 18, 2020 and ending at 5:00 p.m. Friday, June 19, 2020.
The public comment materials can be found at www.portlandoregon.gov/bes/2020SWMM. Available information includes:
Draft 2020 SWMM for public comment.
