During the summer of 2018, Bureau of Environmental Services (BES), Portland Parks & Recreation (PP&R) and the U.S Army Corps of Engineers, will work together on a large-scale habitat enhancement project that benefits wildlife in the Oaks Bottom Wildlife Refuge.

The project will improve hydrology and habitat for protected wildlife species, including amphibians, reptiles, birds, bats and salmon. Right now, migrating salmon cannot safely access Oaks Bottom Wildlife Refuge on their journey to and from the Pacific Ocean because an existing culvert and water control structure blocks fish access into the refuge.

Construction Updated - July 2018

Thank you to the neighbors of Oaks Bottom and the users of the Springwater Corridor! The trail closure started on Monday, July 9, after being postponed a week to accommodate the July Fourth holiday and the Blues Festival. The temporary closure will continue as planned through October 31. Our street teams were out on Monday morning providing last minute reminders about the closure.  As people adjust to alternate routes, the traveling public is asked to be alert, respectful and patient as travel patterns adjust.  The improvements to habitat for protected wildlife species and new amenities for trail users will provide benefits long into the future.

PROJECT UPDATE: What has happened so far?

  • Construction materials continue to be delivered to the site by rail.
  • The project team partnered with Xerces Society to salvage approximately 300 native freshwater mussels from the wetland and transported them to the Columbia Slough where they will remain until construction is over. 

PROJECT UPDATE: What will happen next?

  • Crews will install temporary coffer dams upstream and downstream of the project area to isolate the area and allow construction work to occur.
  • A fish salvage team will collect any fish remaining in the wetland and transport them away from the project area and out of harm’s way.
  • Construction crews will begin to excavate and grade new tidal slough channels to improve hydrology and wetland habitat.
  • A barge will arrive soon carrying additional construction equipment, including the crane that will be used to position the prefabricated culvert sections.
  • The rails will be removed and an open trench will be cut through the berm to allow for installation of the culvert. After installation, the berm will be refilled and the tracks and trail replaced.

Project impacts affecting Springwater Corridor Trail

The Springwater Trail at the project site will close between July 9 and October 31, 2018.  

The trail will be OPEN to the wildlife refuge but CLOSED as a through route - crews are cutting through the trail and land underneath it during construction and will replace the trail and adjacent railroad tracks upon completion..

BES worked with the Portland Bureau of Transportation (PBOT) to identify two main recommended alternate routes during the closure of the corridor. 

  • The Willamette Greenway Trail on the west side of the Willamette River
  • The new SE 19th Avenue Greenway connecting to the 17th Avenue Bike Lane on the east side of the river

Signage and maps will be distributed to show options so that bicyclists and pedestrians can make informed decisions about alternate routes during the closure.

Pedestrian, bicycle, and auto access to the Oaks Amusement Park and the Oregon Yacht Club floating home community will be maintained throughout the project.
