Springwater path damaged by erosion

A downed tree on the banks of the east side of the Willamette River about one mile south OMSI on the Springwater Corridor Trail has damaged the popular multi-use path.

Portland Parks & Recreation spokesman Mark Ross says the “trail failure” was caused by a cottonweed tree that fell earlier this month which led to the soil near the path becoming unstable.

“Trail users are asked to slow down in this area, yield to the slowest traffic, and be considerate of other trail users,” says Ross.

The trail and the safety precautions are set to stay in place until the riverbank is stabilized and the trail is repaired. Parks is working with the Bureau of Environmental Services (BES) to figure out how to redesign the bank to make it more stable. A geotech engineer with BES has determined that the existing path is stable and Parks staff are monitoring the path daily for any signs of further erosion.

Here’s another image of the damage sent to us by the Parks Bureau

With more rain in the forecast, I don’t expect this getting fixed any time soon. Use caution when riding on this portion of the path until further notice and please drop us a line if you notice any developments.

    I’m going to guess that those bollards will stay put longer than the ones put up recently on Lovejoy and by the Condor/Terwilliger intersection….

        Oh, wait–maybe they are…looked too quickly at the picture…

    So I guess this is nothing to do with the trucks they recently had on the springwater fixing the lines going over the trail!

      You don’t have to guess. It was soil erosion due to a downed tree near the bank. This is what nature does.

    I spend a lot of time paddling along the area between Ross Island and the shoreline along where the Springwater is. I have seen numerous erosion blowouts in this area.

    Rivers move, and the river wants to take over the area where the Springwater currently sits. It may not happen relatively soon, but the Willamette’s course will eventually shift, and this section of the Springwater will have to move.

      No, engineers can protect the bank from movement. The Willamette is a managed system, and reinforcement will ensure the river stays where we want it. It just takes active management. The Willamette hasn’t been allowed to meander naturally for over 100 years – see for example the seawall in Portland.

        Silly engineers and their need to “manage” nature.

          You wouldn’t have drinking water in Portland right now if these silly engineers weren’t out doing what they are doing.

            I don’t deny that. I was just poking fun at a certain point of view – not saying it is any more or less valid than my own.

    I saw this when they put it up and was very amused. It’s almost like the bank is a caged animal they’re trying to protect cyclists from.

    there was plenty of warning, I watched it slough off for the last 2 years.
    Thats not the only spot either. bit closer to Ross Isl Br near the picnic table. (MP1)
    and Yeah…those repair trucks are brutal on the trail.

    A “cottonweed” tree! That’s a good one. Cottonwoods grow fast, they colonize disturbed environments… yes, I guess you can call them weeds.

    yeah… In the same vicinity, there are 3 or 4 areas that have been covered in sandbags and black plastic after sloughing off in last years high water. Hopefully the City will repair the previous slides as well.
