Project fact:

Untreated old growth lumber was discovered during the restoration and construction process. RestorCap worked with local mills to carefully remove and repurpose over 80% of the wood products at the site. Additionally, more than 2000 untreated pilings were removed from the shoreline and nearly all of this was sent to local lumber mills for recycling.


The Linnton Plywood Mill played a critical role in achieving economic prosperity during the 1900s. At its peak, the local mill employed 250 people and processed lumber 16 hours a day, six days a week. The mill closed in 2000 and remained vacant until RestorCap purchased the property in 2015. After purchasing the site, one of our firm’s priorities was to appreciate and acknowledge the mill’s century-long history while restoring and supporting natural wildlife.

Once fully restored, the property will provide critical off-channel habitat for juvenile salmonids in the Willamette River and be home to over 80,000 native trees and shrubs (a variety of over a dozen different types). The site will also provide upland and riverine habitat to many native birds and animals. Linnton Creek, which flows from Forest Park, provides important cold-water inflow to the habitat.

We remain committed to respecting the mill’s rich history, with the old administration building to serve as a research center for university students and office space for local nonprofits.

This project is the first of its kind in the nation to offer to offer dual-purpose credits. The years-long process of creating dual-purpose credits allows purchasers to apply environmental credits interchangeably – either towards an NRD liability or dredging/capping mitigation offsets that will be required as part of the river cleanup.

Parties involved with the Portland Harbor Superfund site can purchase Natural Resource Damage credits (DSAYs) through the Linnton Restoration site.
