New Project Starts Near Springwater Corridor Trail


Stream restoration and sewer pipe repair go hand-in-hand.

Construction began last week on a new restoration project in Johnson Creek!

The Luther Road Habitat Restoration Project will repair a 76-inch sanitary sewer pipe and manhole in Johnson Creek that are exposed due to erosion and are at risk of failure.  The project also includes moving and restoring the channel of Johnson Creek and restoring natural floodplain functions. 

This will help protect the sewer infrastructure, protect nearby private property and public health, and improve water quality and stream habitat for endangered salmon, trout and other sensitive species.

The picture above shows the exposed pipe and unstable, erroding stream bank. 

view of the site before restorationThe project site (shown at right) is on a 10-acre parcel along Johnson Creek near the intersection of SE Luther Road and the Springwater Corridor Trail.  

The property was purchased by Environmental Services, North Clackamas Parks and Recreation District (NCPRD), and Metro.  NCPRD plans to develop a park at the site in the future, and will protect the 6-acre restoration project as a natural area.


The project includes:

  • 2,000 feet of new stream channel and 5 acres of new floodplain
  • Sewer pipe will be reinforced and buried in place, eliminating a significant public health threat
  • 6 acres of improved stream and upland habitat for fish and wildlife
  • 3,000 feet of new trails with interpretive signs
  • Over 13,000 new native trees and shrubs

The Luther Road project is part of Environmental Services and partners’ ongoing work to improve floodplain and stream functions, water quality and habitat in the Johnson Creek Watershed. A similar project was completed in 2006 at Tideman Johnson Park (see the update on that project here).


CONSTRUCTION ALERT FOR SPRINGWATER CORRIDOR TRAIL: During construction, vehicles will access the site from SE Luther Road at SE 73rd Avenue and across the Springwater Corridor Trail. About one construction vehicle will cross the trail onto the site every ten minutes. If needed, a flagger will direct traffic at the crossing point. Trail users will not be stopped unless it is necessary for their safety. Signs placed on the trail in advance of the crossing will alert users of the construction and possible delays.

Please email to receive weekly updates by email.

Crows Try to Compromise PSU Ecoroof Research


a crow tossing a cupWhat does biodiversity on Portland ecoroofs look like and how does it compare with other cities?

That’s what a partnership between the Zurich University of Applied Sciences and Portland State University hopes to find out. Using beetles as a bioindicator and using pitfall traps to collect beetles, nine Portland ecoroofs as well as ground sites are being sampled throughout this summer. The catch will be identified and compared with the results of similar studies taking place in San Francisco, Mexico City and Basel, Switzerland.

Ground-dwelling insects fall into the vinegar-filled cups placed flush into the soil, and the cups are lightly covered to prevent the sun and rain from weathering the contents. However, on multiple ecoroofs the cups have been repeatedly pulled out and tossed around. A security camera was set out and the vandals were filmed red-handed – crows!

We know ecoroofs do a great job of managing stormwater. Research specific to our region on the simultaneous benefits that ecoroofs provide, such as the urban habitat they provide or energy savings, is something we love to see more of. We’ll keep you posted of their results, particularly after some form of crow-baffle is installed.

Hug a Tree at Hoyt this Saturday


Does it get any more Portland than this?

hugging trees in Hoyt Arboretum last yearHere’s a simple, fun thing you can do this Saturday, July 12:  Join the world’s largest tree hug at Hoyt Arboretum. 

Last year, Portland set the official record.  Now, we need your help to defend that title and help celebrate all the new trees planted in Portland recently. 

When: Saturday, July 12, 2:00 p.m.

Where: Hoyt Arboretum, SW Knight Blvd and SW Kingston Blvd.

Who: You, your friends, and family (kids make great huggers!)

Find more details about the event and a link to pre-register at  The event is free, but pledges to participate are encouraged!


This event is sponsored by some of our partners in tree planting: Friends of Trees, Hoyt Arboretum Friends, Portland Parks & Recreation, and Treecology, Inc.

Rare fish sighting in Saltzman Creek


Cutthroat trout found in Forest Park stream.

Biologists from Environmental Services, conducting routine monitoring in Forest Park, recently found a surprise in Saltzman Creek …a cutthroat trout! 

small trout being measuredSalmon and trout species are rare in Forest Park’s streams because long culverts under Highway 30 and the industrial corridor limit or prevent fish passage to and from the Willamette River. 

This lone cutthroat may be part of a resident population that existed in Saltzman Creek before downstream culverts blocked passage.

Coastal cutthroat trout are a state-listed species of concern in Oregon.  They generally spend more time in fresh water than other migratory Pacific salmon and trout.  

This fish swam happily away after being identified and measured. 

Environmental Services staff sample for fish, water quality and other environmental conditions at sites around the city as part of the Portland Area Watershed Monitoring and Assessment Program (PAWMAP).  

PAWMAP helps us track long-term progress towards the city’s environmental goals and regulations, such as the Clean Water Act and Endangered Species Act.  PAWMAP started in 2010 to replace older monitoring methods with a more coordinated, cost-effective approach based on that of the Environmental Protection Agency (EPA).  Learn more about why we do environmental monitoring.

Tabor to the River Turns Six!


This program's success continues because of community partners.

neighbors planting street treesThis year marks the sixth anniversary of the Tabor to the River program.  Tabor to the River combines sewer improvements and green infrastructure projects.  This helps save Portland sewer and stormwater ratepayers more than $60 million in costs to address aging pipes and basement sewer back ups in SE Portland.

Check out the new summer newsletter here. The newsletter highlights the milestones this program has accomplished and has resources and opportunities for the coming year. 

Since 2008, Tabor to the River projects have:

  • Repaired 3 miles of sewer pipes
  • Built 215 green streets
  • Removed 18.8 million gallons of stormwater from the sewer system annually
  • Planted 770 new street trees
  • Worked with property owners to construct 72 rain gardens and other stormwater management projects on private residential and commercial properties that are treating stormwater runo­ff from three acres of hard surface!  Check out our earlier post on some recent rain garden projects
