Fall at Mason Flats Wetland

0 Comments

Has this been a beautiful Portland fall, or what?!

Workers checking up on the Mason Flats wetland and water quality facility snapped these shots to share.  Environmental Services completed this project along the Columbia Slough this spring.  The native vegetation is already thriving and ready to help filter this winter's stormwater runoff. 

Here's our green-- and gold and red-- infrastructure at work!

Multnomah Village Goes Green

0 Comments | Add a Comment

New green streets planted on Capitol Highway will soak up street runoff

Capitol Highway in Multnomah Village is an important parking area for the Village and a major thoroughfare for the neighborhood.  When it rains, oils, metals, brake dust and other pollutants from this high use area wash into nearby Vermont Creek, a tributary of Fanno Creek where water quality and habitat resources have been significantly impacted by development. 

Back in March, Environmental Services started construction on a series of green streets in the Village Core to treat pollutants running off the roadway and absorb rainwater with street trees. They've also been designed to encourage walking through widened sidewalks and bicycling through a reconfigured parking layout. Facilities were planted last month and are looking great.

More Spots for Salmon: A New Culvert on Stephens Creek!

0 Comments

Here's more news about in-water restoration projects constructed summer and fall. 

Today we’re excited to share pictures of a project near the confluence of Stephens Creek and the Willamette River (just south of this spot).  Perhaps you saw some of the action in person if you regularly travel SW Macadam Avenue (Highway 43).

Previously, Stephens Creek flowed through two corrugated metal culverts under the Lake Oswego trolley track and the regional pedestrian and bike trail. By state law, culverts must provide for fish passage, and these did not. 

old metal culverts on Stephens Creek

Multnomah County's Sellwood Bridge replacement project triggered the opportunity to replace the old metal culverts with a 16 foot wide, 90 foot long arched cement culvert.  This essentially creates a bridge over the stream instead of trying to fit the stream through a metal pipe.

The new cement culvert and restored stream improves off-channel fish habitat, so migrating salmon and other fish have a place to get out of the current to rest and feed.  The large size allows the stream to be more naturally connected to the tidal flows of the Willamette River and improves the ecosystem of the area.

Stephens Confluence natural area

 

This culvert project is right next to a project Environmental Services and partners completed in 2008 to restore the confluence of Stephens Creek.  Together, the two projects and other efforts in the larger South Portland Riverbank natural area are protecting and improving water quality and habitat for Portland’s people, fish and wildlife. 

 

The Sellwood Bridge area is still under construction, but you can visit Stephens Creek upstream, in the Stephens Creek Nature Park
