“Volunteers will work at various project sites throughout the watershed and then gather together for a celebratory lunch. Projects will include native plant installation and invasive species removal. Registration is required to receive post-work lunch. Please come dressed to work outside – wear closed-toe shoes, long pants, and weather-appropriate clothing (we will work rain or shine). Gloves, tools, and food will be provided. Each site will have a TCWC leader to help your group at your designated site.”

The event begins at 9:00 a.m. and will wrap up around 1:30 p.m. Please see the event website for more information and to register:

Environmental Services works with partners in the Tryon Creek watershed on projects and programs that cumulatively work to improve watershed health. You can learn more about this collaboration on the Environmental Services website here:

KOIN 6 News on Foster Floodplain and the Flood that Wasn’t

0 Comments | Add a Comment

The added flood storage means less frequent flooding in the surrounding neighborhoods and businesses

During a break in heavy rains on Thursday, February 9th, KOIN 6 met up with Environmental Services at Foster Floodplain Natural Area to see how the floodplain was working to prevent flooding of downstream neighborhoods along Johnson Creek. Good news – the high flows of Johnson Creek were spilling into Foster Floodplain as designed instead of onto busy SE Foster Road.

Foster Floodplain Natural Area detaining flood waters 


As explained on camera by Kate Carone, Environmental Program Coordinator, Foster Floodplain works like a bathtub – holding all that excess rain until it can drain gradually instead of dumping into the creek all at once and causing flooding. Foster Floodplain is one of several restoration projects that Environmental Services has built to alleviate the frequent flooding that has historically plagued neighborhoods along Johnson Creek. Before the restoration project was completed in 2012, SE Foster Road near SE 106th Ave. flooded every other year on average. Foster Floodplain is expected to reduce that flooding to once every six to eight years.

West Willamette Restoration Partnership is Featured in New Story Map

The interactive website highlights the accomplishments of the collaborative project in Southwest Portland

The West Willamette Restoration Partnership (WWRP) recently released a fascinating and informative presentation about a collaborative project in Southwest Portland. The story map was created by PSU student Andrew Addessi. Take a look here: and scroll down to learn more about how WWRP is working to connect Southwest Portland’s urban forest. 

Environmental Services is a founding member of the WWRP. The group was convened in 2006 to build and empower collective efforts to remove invasive species, restore wildlife habitat, and elevate local stewardship in Portland’s west side Willamette River sub-watersheds in SW Portland.  The forests in this area are important for wildlife connectivity between Forest Park and Tryon State Natural Area.  

In 2009, Environmental Services built an important foundation for the effort through a study of the Marquam/Terwilliger area of SW Portland in a series of Subwatershed Improvement Strategy reports.  The reports outline many projects that will improve overall watershed health by enhancing water quality and stormwater management and creating opportunities to protect and restore habitat for birds, fish, mammals, amphibians, and people. WWRP is tackling some of these projects and is making large strides toward accomplishing our watershed health goals in the area.

WWRP is built on the active partnership of the many groups, including the Columbia Land Trust, the Backyard Habitat Certification Program, Environmental Services, Portland Parks & Recreationthe SW Watershed Resource Center, the Friends of Marquam Nature Park, the Friends of Terwilliger with support from the Homestead Neighborhood Association, Oregon Health & Sciences University:, and the West Multnomah Soil & Water Conservation District.

Environmental Services’ Lower Slough Refugia Project to Receive an Achievement Award from the Columbia Slough Watershed Council

0 Comments | Add a Comment

A series of log jams installed in the Columbia Slough will provide refuge for endangered fish

The Columbia Slough Watershed Council will highlight the Lower Slough Refugia project at the 2017 Slough Celebration Gala next week. The event takes place on Friday, February 10, 2017 from 6:00 PM – 9:00 PM at the Melody Ballroom.

In 2015, Environmental Services placed 35 engineered log jams in the Lower Columbia Slough. The slough’s water supports endangered steelhead, coho and Chinook salmon and provides refuge from the strong currents and predators in both the Willamette and Columbia Rivers. This is critical for young fish who need resting and feeding places along the route to the Pacific. Tangled log jams that provide refugia in today’s rivers and slough are few and far between because of past dredging, armoring, and development. By using water-based construction methods, this project improved habitat without impacting existing natural resources or the slough levee.

In addition, Environmental Services produced a short video tour of the project after completion:

Environmental Services Tree Program Brings 500 Trees to Commercial and Industrial Areas this Winter

1 Comment | Add a Comment

Planting remains on schedule despite this winter’s snow storms.

The Environmental Services Tree Program is planting street trees with 134 commercial and industrial partners this winter. More than 500 trees will be planted across Portland east of the Willamette River, including North and East Portland.  Planting remains on schedule despite this winter’s snow storms.

This is the second year of a city-wide project that works businesses, non-profits, and multi-family residential properties.  Last year the program planted 212 street trees with 64 partners, mostly west of the Willamette River. Crews planted an additional 400 street trees with multi-family residential properties on both sides of the river.

Every tree planted in Portland contributes to cleaner rivers and streams. Environmental Services has a longstanding planting program to bring street trees to areas that lack trees. 

Environmental Services contractors will plant trees and water them for their first three summers.  Property owners then assume responsibility for tree care.  Planting this year’s trees began the first week of December and is expected to continue through February.
