Linnton Mitigation Bank

Portland, Oregon

Overview:

The Linnton Restoration Site provides critical off-channel habitat for juvenile salmonids in the Willamette River and has over 80,000 native trees and shrubs planted. The site also provides upland and riverine habitat to many native birds and animals. Linnton Creek, which flows from Forest Park, provides important cold-water inflow to the off-channel habitat.

This project is the first of its kind in the nation to offer dual-purpose NRDA and 404 credits. The years-long process of creating dual-purpose credits will allow purchasers to use credits either towards an NRD liability or as mitigation for impacts to resources under Section 404 of the Clean Water Act. 

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

Site Credits Available:

    • Natural Resource Damages (NRD)
    • Dredging/capping mitigation offsets
    • No-net-fill

Total Acres: 25

Site History:

The Linnton Plywood Mill, and its predecessor the Clark and Wilson Lumber Company, played critical roles in the Linnton area achieving economic prosperity during the early to mid 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 objectives was to acknowledge the value of the mill’s century-long history while restoring riparian habitats and supporting wildlife.

Project fact:

During the restoration process, untreated old growth lumber was discovered from the old mill building. RestorCap worked with local mills to carefully remove and repurpose over 80% of the salvageable 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.
