Oregon Field Guide covers Ecoroofs


Tom Liptan's garage - May 2009

Did you happen to catch Oregon Field Guide last night (Thursday,

February 18th) on Oregon Public Broadcasting (OPB)? They provided a great overview of ecoroofs in Portland, featured Tom Liptan from BES and Erin Schroll from Oregon State University. You can view it online here, or catch it again when it re-airs this Sunday, February 21, at 6:30 PM. Check for your local channel listings.


If you watched the episode, you might have heard how much rainfall the City of Portland receives during one year. 86 billion gallons per year - that's a large number. Vince Patton, OPB producer of the episode, offers a more in-depth blog post here that explains how BES calculates this number and how you can calculate stormwater runoff from your own property.


Many thanks to Vince Patton and the team at Oregon Field Guide and OPB for the great episode!
