Stormwater Management Manual

Stormwater Management Manual 

The City of Portland revised its Stormwater Management Manual in 2008, reorganizing chapters and most of the appendices to make it easier to read and use. 

Changes include:

  • Clarification of the stormwater hierarchy
  • New typical design details
  • All new forms and submittal guides
  • A new Presumptive Approach Calculator (PAC)

The new PAC allows more flexibility in sizing vegetated facilities using infiltration testing results. The PAC and the PAC User's manual are only available online. 

Printed 2008 Manuals are available for $25 each. You can purchase a paper manual or pick up the free compact disc version at the Development Services Center, 1900 SW 4th Avenue in Portland. To get a free CD by mail, please call 503-823-7103. 

PLEASE NOTE:  If you encounter PDF printing problems with any of the files, try this: In the "Print" dialog box click the "Advanced" button and enable the "Print as Image" check box.
