Multnomah Village Goes Green for Multnomah Days

Join your neighbors and staff from Environmental Services at the 106th Multnomah Days Street Festival on Saturday, August 16 in Multnomah Village

Join your neighbors and staff from Environmental Services at the 106th Multnomah Days Street Festival on Saturday, August 16 in Multnomah Village.

The biggest little parade will march right past six green street facilities completed in 2013. These aren’t just ordinary landscaping. The facilities capture and treat stormwater runoff from 1.5 acres of pavement.

Capitol Highway in Multnomah Village is an important parking area and a major neighborhood thoroughfare. When it rains, oils, metals, brake dust and other pollutants from this high-use area wash into nearby Vermont Creek, which flows to Fanno Creek and the Tualatin River.

Trees absorb rain to reduce stormwater runoff, and the new green street facilities protect water quality and enhance the neighborhood. The green street project also widened sidewalks and reconfigured the parking layout in the village core to benefit pedestrians and cyclists.

Find out more about Fanno Creek and projects for healthier streams on the Fanno Creek Watershed page. Find out the details on Multnomah Days at www.swni.org

 

Celebrating Progress Towards a Healthier Columbia Slough

Slough Regatta flags   Mayor Hales speaking at Regatta

This year's Columbia Slough Regatta was a great success, with over 450 people coming out to paddle on the Slough for the 20th anniversary event on August 3.

Mayor Hales and city staff touring the SloughSpecial thanks to Mayor Charlie Hales and his wife Nancy for joining BES staff for a paddle tour of restoration project sites along the Slough.  

Efforts like the Combined Sewer Overflow Control Program, replanting trees and shrubs along the bank through Watershed Revegetation, and constructing wetlands to filter stormwater are bringing back healthier conditions in the Slough.

Before and After: The Tryon Creek Iron Mountain Project

Keeping sewage out of the water and improving stream habitat.

This summer marks five years since completing the Tryon Creek Iron Mountain Streambank Restoration and Sewer Maintenance Project in Southwest Portland. We are excited to share some photos showing the dramatic changes that have taken place along this part of Tryon Creek. 

The Iron Mountain Project is located just upstream of the Iron Mountain Bridge in Tryon Creek State Natural Area. In 2008 an exposed sanitary sewer line along Tryon Creek posed a threat of leaking sewage into the stream.

The photos above show the exposed sewer infrastructure, eroding stream banks, and invasive plants contributing to problems there.

stream and bank after constructionEnvironmental Services’ project protected the sewer infrastructure, restored stream bank conditions, and enhanced 200 feet of stream and over three acres of habitat. The project enhanced stream and wetland functions to benefit threatened salmon and other native fish and wildlife.

The photo to the left shows the same spot, just after construction.  Look for the large fir tree trunk in the background of each photo for comparison.

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

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.
