International Recognition for Portland’s Ecoroof Program

Portland’s reputation as a leader in ecoroof technology continues to grow. The city has received a 2013 Green Roof Leadership Award for Municipalities from the International Green Roof Association (IGRA). 

The Ecoroof Program's Amy Chomowicz accepts the Green Roof Leadership Award at the 2013 International Green Roof Congress


Portland received the award at the 3rd International Green Roof Congress held in May in Hamburg, Germany. Over 250 participants from more than 40 countries attended to learn about future trends for roof and façade greening.

“It’s great for the city that Portland is receiving international recognition for our innovative stormwater management,” said City Commissioner Nick Fish. “Ecoroofs have many benefits, and one of the main benefits is that they make the sewer system more efficient and reliable by acting like giant sponges soaking up rain and keeping stormwater runoff out of our sewers.”

The association noted that Portland’s work to promote green roofs is encouraging other cities around the world to adopt the technology to manage stormwater. “We’re honored to receive this award,” said Bureau of Environmental Services Director Dean Marriott. “And we are pleased that our efforts to promote green roofs are being recognized."

Green roofs replace conventional roofing materials with soil and vegetation. They manage stormwater onsite and provide many other human health and environmental benefits. Over 500 green roofs cover more than 1.5 million square feet of rooftop in the City of Portland.

World Environment Day Concluded with Innovation Celebration


Local leaders showcased the Portland region's green infrastructure to the world

The month-long festivities for World Environment Day wrapped up with a celebration of Portland and Oregon's environmental ethic and a sampling of environmental innovations.  Representatives from local companies, colleges and universities, community organizations, tribes and public agencies showcased their work to elected officials from the region and representatives from the United Nations Environment Program's North America Office.  One example is Lucid Energy, a company pioneering in-pipe turbines for city water pipes to generate electricty. 

Photojournalist Gary Braasch included Portland's green infrastructure projects--green streets managing stormwater and natural areas soaking up the rain-- in his photo show about the impacts of climate change and the solutions that communities like ours are using.  To see some of Gary's work, visit

Artist Kenji Williams brought a slice of his awe-inspiring Bella Gaia performance, which we hope comes back to Portland for everyone to see in its full length!

City Green Partner: Mt. Tabor Weed Warriors


Inspired by last week's World Environment Day, City Green will feature some of Environmental Services' community partners for healthy watersheds.  We'll do an occassional post about some of these champions of Portland's green infrastructure.  These are the people who spend their weekends and evenings to make our rivers and streams healthier. 

Today's partner is....the Mt. Tabor Weed Warriors.  

Volunteer Weed Warriors

Many of our city's parks and natural areas are made safer and more beautiful through the efforts of friends and neighbors. At Mt. Tabor Park, the Friends of Mt. Tabor Park (FMTP) Foot Patrol keeps the park safe and clean, FMTP volunteers inform visitors from around the globe about the park at the Visitor Center, and FMTP Weed Warriors restore natural areas by removing invasive plants and planting native plants.

The FMTP Weed Warriors are key partners in the city's effort to remove invasive plants and plant native plants in the natural areas at Mt. Tabor Park (find out more at This reduces stormwater runoff to improve watershed health, enhances habitat for wildlife, and safeguards Mt. Tabor's forests. Photos and more information about Weed Warrior events are at  In April, we posted about the amazing trillium comeback on Mt. Tabor, thanks in part to the Weed Warriors' work.

Want a fun way to be active outside, meet friendly neighbors, and help improve Mt. Tabor Park?  Join a Weed Warriors Saturday event! They meet at the parking lot next to the Mt. Tabor Park amphitheater on the last Saturday of every month (March through October). The next opportunity is Saturday June 29, 9 a.m. - noon. Find more information at
