Construction Starts on Terraced Rain Gardens Project


Green Infrastructure along I-5 in SW Portland will help protect Tryon Creek

rain garden project construction signWondering about the new construction along I-5 in Southwest Portland? Construction started in July on our Terraced Rain Gardens Project.  


Environmental Services is partnering with Oregon Department of Transportation to construct a series of terraced rain gardens to treat stormwater runoff at the intersection of Interstate 5, SW Barbur Boulevard and SW 26th Avenue.  This project will protect water quality in Tryon Creek.


Stormwater runoff from these roads currently drains directly to Tryon Creek and carries pollutants to the creek. The rain gardens will slow runoff, reduce erosion and allow pollutants to settle out before the stormwater enters Tryon Creek. Tryon Creek is among the few streams in the Portland metro area with a run of steelhead trout, and coho salmon have been recorded spawning in the creek.

A Lamprey at Luther Road

Check out this critter found in Johnson Creek

We recently posted about the start of a new stream and sewer pipe protection project in SE Portland.  Construction is now well underway on the Luther Road Habitat Restoration Project in Johnson Creek.

Rescuing fish in the project area before construction is an important step in our restoration projects.  Check out the Pacific lamprey that was relocated as part of this effort.

City Green Partner: Portland Surfrider Foundation


This group of surfers helps keep our streams, rivers and ocean clean.

Portland’s chapter of the national Surfrider Foundation focuses on awareness and education around litter and its effect on our rivers, streams and the ocean.

For the past two years, Surfrider Foundation has partnered with Portland’s Green Street Steward Program. Volunteers for two groups (one in SE Portland the other in the NE Portland) get together once a month and pick up litter from our streets and green street facilities. On average between 50-80 gallons of trash are removed in just a couple of hours.

Check out this video, as well as pictures from their recent event cleaning up North Portland after the 4th of July holiday.

A big thanks to Portland Surfriders for their awesome volunteer spirit. Picking up litter may seem like an unglamorous task, but this group keeps it fun!  Their work helps locally – keeping trash out of our rivers, streams, sewer system, and green streets.  It makes our neighborhoods cleaner, and trickles down to a cleaner ocean, too.

Portland Watershed Monitoring and Bird Surveys

Environmental Services biologists are monitoring populations of Portland area birds, valuable indicators of ecosystem and watershed health

The Portland Area Watershed Monitoring and Assessment Program (PAWMAP) evaluates water quality, watershed conditions, habitats and wildlife. Since 2010, Environmental Services has used this citywide monitoring to evaluate and protect our watersheds and to meet state and federal requirements and city goals. In recent months, bureau biologists have been surveying Portland’s bird population as part of this effort. These surveys are called point counts. A biologist identifies and tallies all birds seen and heard over an eight minute period, creating a bird census. Birds are valuable ecosystem indicators and contribute to a holistic assessment of watershed health.

The biologists are also keeping tabs on bird nests in Environmental Services construction project areas. These nests are protected and monitored to ensure that our construction activities cause no harm and support urban wildlife.  

Here are some great photos from the field surveyors.

Join the fun at the Lents Street Fair on Sunday, July 27th.

For almost 20 years, Environmental Services has been working to improve conditions in Johnson Creek and its floodplain in the Lents neighborhood. This Sunday July 27th, the Johnson Creek Watershed Team will be at the Lents Street Fair to help celebrate everything that makes Lents an awesome place to live, work and enjoy nature.


Maggie and Marie from Environmental Services will be fitting fair-goers with fish hats, which you might have seen at Sunday Parkways! Stop by and say “hi!” and learn about what’s happening with efforts to restore Johnson Creek and bring back more salmon and trout.  And while you’re there, be sure to check out the fabulous array of Lents grown food, crafts and music.

We hope to see you there!
