2008 Stormwater Management Manual

The City of Portland adopted a revised Stormwater Management Manual on January 2, 2014.  From January 2, 2014 project designers had the option of using the 2008 Stormwater Management Manual or the 2014 SWMM. As of April 2, 2014, project designers must use the 2014 SWMM. The 2008 SWMM information will remain available on the internet as reference.
