West Lents Floodplain Restoration Project


Environmental Services is designing a floodplain restoration project that will reconnect Johnson Creek to its historic floodplain, restore habitat for salmon and other wildlife, improve water quality, and provide space where flood waters can safely spread out and partially soak into the ground.

The project will take a natural approach to reducing local flood risks that also improves fish and wildlife habitat along Johnson Creek and is intended to be a community amenity. The restored floodplain also improves the water quality of Johnson Creek by allowing sediments in high water to settle onto the floodplain. Once the floodplain restoration project is completed, this restored area will allow a wider range of creek restoration and storm water management options to be considered as part of the project and provide additional space for floodplain restoration.

The floodplain restoration project is in the very early stages. Currently, the work is focused on assessing the current ecological condition of the area. In addition, BES is working to "abandon" several sections of right of way in the project area.  This process is known as street vacation.  These sections of right of way are old streets that are no longer in use.  By vacating these streets, BES will be able to better control access to the site as well as use this additional acreage as part of the restoration area.

Initial investigations and design work will continue through 2022.  Construction is not expected to begin until Summer of 2022 and will take approximately one year to complete.

Street Vacation

The following streets are proposed for street vacation:

  • SE Lambert Street
  • SE Malden Court
  • SE Malden Street
  • SE 89th Avenue

Once street vacation is completed, Environmental Services and Portland Parks & Recreation will install a locking swing gate on SE Lambert Street near the Springwater Corridor Trail to limit vehicular access. The existing pavement will remain for the time being to facilitate emergency vehicles and property management.  Eventually these streets will be removed when construction begins on the floodplain restoration project. Unneeded utilities will also be removed as part of the restoration project.

Frequently Asked Questions

What is a Street Removal (Vacation)?

Vacating street right-of-way removes the public’s interest and returns control of the land to the underlying fee owner(s) – most often, to the abutting property owners.

The street vacation process may solve development-related problems caused by the existence of unneeded public right-of-way.  For example, an undeveloped street through two parcels of land might be vacated to allow better development of the property.

How long does street vacation take?

Street vacation process can take 8-12+ months, depending on the complexity of the street.
