Help the Xerces Society and Crystal Springs Partnership rescue native freshwater mussels.

0 Comments | Add a Comment

Sunday July 7 and Monday July 8, 2013, 9 am – 2 pm each day

Why rescue mussels?

Freshwater mussels are the most threatened organisms in North America.  Previous surveys by Xerces have shown that Crystal Springs Creek supports large populations of native Floaters (Anodonta).  The City of Portland is working with the US Army Corps of Engineers to restore the Westmoreland Park duck pond to a more natural stream channel and planting native vegetation to help cool Crystal Springs Creek.  This restoration project can benefit native mussels in the long term, but right now, they need our help to be moved out of the areas that will be dewatered during the project, or they will not survive.

Who can help?

Volunteers must be 18 years or older and may register for one or both days. No prior experience is required. Be prepared for a day in and around the water. Closed toed shoes are a MUST! 

What will the work involve?

Volunteers will help survey for and collect native mussels.  Mussels will also be tagged, measured, and relocated out of harms way.

Ecoroof Symposium Presentations Posted Online

0 Comments | Add a Comment

Videos are available from the 2013 Ecoroof Symposium on May 2, 2013

The 2013 Portland Ecoroof Symposium took place on Thursday, May 2nd. The event marked the 5th consecutive year for the BES Ecoroof Program’s major outreach event. This year’s event continued the ongoing dialogue between the City of Portland, municipal and non-profit partners, and the private sector, focusing on the business case for Ecoroof development in the City of Portland.

The program for this year’s event was developed to reach developers, construction firms, and building design professionals. Presentation topics focused on ecoroof costs and benefits, LEED certification, stormwater management regulations, and low-maintenance no-irrigation design. 

All presentations are now online and available for viewing. They can be accessed individually on the event web page or you can check out the entire program by accessing the event YouTube page. (You can find all the videos from our 2011 and 2012 events as well.)

Click below to see the Keynote Presentation by Michael Berkshire of the City of Chicago, and the Ecoroofs and Healthcare Facilities presentation by Elizabeth Hart of Tremco. 


Many thanks to all the speakers, vendors, sponsors, and volunteers that made the 2013 Ecoroof Symposium a success!

OPB covers Klickitat Neighborhood Greenway Project

0 Comments | Add a Comment

Several green street facilities span 60 blocks of the northeast Portland street as part of the Neighborhood Greenway network

OPB posted a great video and article yesterday on the Ecotrope Blog about the Klickitat Neighborhood Greenway Project in Northeast Portland. Environmental Services has installed two dozen green street facilities along 60 blocks of NE Klickitat Street. The project is part of the greater neighborhood greenway network intended to manage stormwater and improve safety for pedestrians and bicyclists on low volume residential streets. 

Green streets are one of the many green infrastructure tools used by the City of Portland. By soaking up street runoff, the 1,300 green street facilities across the city make our infrastructure more resilient to large rain events and climate change.  Integrating them into the neighborhood greenways network makes great sense, since their plants and soil also improve air quality, cool city temperatures, provide habitat, and enhance community. Residential green streets have also been great opportunities for neighbors to participate with the Green Street Stewards program.

Dispatch from the Columbia Slough Watershed


Annual outings draw hundreds to the Slough

Summer is here and that means there's a lot going on in Portland's watersheds. Here are some updates from recent events in the Columbia Slough

Stay tuned to the City Green blog for future events on the Slough (like the Annual Regatta, coming up on July 28!), and updates on restoration projects underway this summer.


Explorando el Columbia Slough

Over 450 people attended Explorando el Columbia Slough at Whitaker Ponds last month. Environmental Services has been a sponsor of this bilingual nature festival since the Columbia Slough Watershed Council launched the event 12 years ago. Participants enjoyed music and dance, games, food, guided canoe trips on the slough, live birds and hands-on environmental activities. Over 90 volunteers and staff from the watershed council and partner agencies worked on the event. Click here to see more Explorando photos on Flickr.


Corps of Rediscovery

It wasn’t quite as epic as the Lewis and Clark expedition, but it was an eye-opening experience for guests on the BES Columbia Slough Watershed team’s annual Corps of Rediscovery slough paddle. Participants in the June 14th event included staff from Mayor Charlie Hales' office, the Division of State Lands, Oregon Department of Fish and Wildlife, Portland Parks & Recreation, Multnomah County Drainage District, the Oregon Department of Transportation, the Portland Water Bureau and Metro. Participants got to see the slough from the water and view stormwater management and restoration projects on a nine-mile paddle from Fairview Lake to the NE 18th Avenue levee.

A no-irrigation ecoroof? In this heat?


The low maintenance, no irrigation design is performing well despite dry, hot weather

Back in February, we wrote about the new specs for a low cost, low maintenance ecoroof , which can help make ecoroofs more affordable for some home and building owners.  The Columbia Boulevard Wastewater Treatment Plant Screenhouse is one of the first ecoroofs in the city to use the red cinder design, a simple lightweight approach that reduces the need for maintenance. Here are some update photos from that ecoroof, now with the sedum in full bloom.  The 5,700 ft² project was installed in 2011 and has never been irrigated.

Several of Environmental Services' facilities have ecoroofs, and this innovative design allows us to keep installation and irrigation costs low while providing all the benefits we get from ecoroofs.  To learn more about ecoroofs, visit the Portland Ecoroof Program website:
