Chad Sorber - "Green Roof Maintenance"

Chad Sorber’s lecture “Green Roof Maintenance: Lessons Learned at OHSU” presented by the City of Portland Environmental Services on May 18, 2012.

Cities across the world are investing in green roofs to combat urban challenges. Portland is a leader in green roofs, and we’ve learned a great deal about their benefits for managing stormwater and greening the city. But more and more is being learned about the true costs and benefits of green roofs and how they offer a better return on investment.
