We are pleased to share that Portland has earned a 2013 Green Roof Leadership Award for Municipalities from the International Green Roof Association (IGRA).

Green roofs, or ecoroofs, replace conventional roofing materials with soil and vegetation.

Ecoroofs have many health and environmental benefits, including making the sewer system more efficient and reliable by acting like giant sponges soaking up rain and keeping stormwater runoff out of our sewers.

We’re proud that Portland is receiving international recognition for our innovative stormwater management.

Over 500 ecoroofs cover more than 1.5 million square feet of rooftop in the city of Portland.
