The City of Portland last revised its Stormwater Management Manual in 2008, reorganizing chapters and most of the appendices to make it easier to read and use.
The revised PAC allows more flexibility in sizing vegetated facilities using infiltration testing results. The PAC and the PAC User's manual are only available online.
