Portfolio

We specialize in revitalizing idle properties, converting environmental liabilities into sustainable assets. Our recent projects integrate remediation, restoration, and strategic redevelopment to create lasting economic and environmental benefits.

Linnton Plywood Mill

Transforming a Closed Plywood Mill to Valuable Mitigation Bank

Location: Portland, Oregon
Historical Use: Plywood Mill
Restored Use: Mitigation Bank
Start Date: 2015
Status: Ongoing
Land: 30 Acres

Challenge: The Linnton Plywood Mill site sat idle for 15 years, attracting vandalism and blight.

Solution: We transformed this former Superfund site, repurposing a 200,000-square-foot abandoned factory into a mitigation bank. Through approvals from a wide variety of federal, state, and local regulators we restored valuable off-channel habitat for endangered salmon species. Our innovative approach created the only mitigation bank in the country that satisfies both Natural Resource Damages (NRD) liabilities while also satisfying Clean Water Act (CWA) criteria.

Impact:

  • Removal of 2,000 shoreline pilings
  • Excavation and placement of 400,000 cubic yards of soil
  • Only US Army Corps-approved mitigation bank in the Portland Harbor Superfund Site
  • Supports ongoing remediation and endangered species preservation

Agency Partners: Portland Harbor Natural Resource Trustee Council, US Army Corps of Engineers, Oregon Department of Environmental Quality (DEQ)

Credits Offered:

  • NRD credits to offset liabilities associated with Natural Resource Damages;
  • Waters and wetlands credits to meet mitigation requirements imposed under Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act; and
  • Floodplain/net fill credits under City of Portland requirements

Time Oil Bulk Petroleum Terminal

Transforming a Bankrupt Bulk Petroleum Storage Facility to Renewable Energy Storage

Location: Portland, Oregon
Historical Use: Bulk Petroleum Storage & Wood Treatment Facility
Restored Use: Renewable Energy Storage
Start Date: 2019
Completion: 2023
Land: 40 Acres

Challenge: A former Superfund site entangled in bankruptcy left 40 acres of prime riverfront industrial land unused for 30 years.

Solution: We led the technical, financial, and legal efforts to clean and repurpose the site. Partnering with Oregon DEQ, we ensured a risk-free transfer for renewable energy storage.

Impact:

  • Transformed an underutilized brownfield into a renewable energy hub
  • Sold to Eolian Energy for solar and wind energy storage
  • Supports Oregon’s zero-carbon goals

Agency Partners: Oregon Department of Environmental Quality

Historic Wood Waste Landfill

Transforming Buried Biomass into Biochar, Soil Amendment, and Permanent Carbon Sequestration

Location: Fort Bragg, California
Historical Use: Wood waste Landfill
Restored Use: Biochar, Soil Amendment, Carbon Credits
Start Date: 2021
Status: Ongoing
Land: 200 Acres

Challenge: A listed 50-acre wood waste landfill contained 500,000 cubic yards of biomass that required regulatory-compliant closure.

Solution: Converting biomass into biochar and organic soil amendments supports landfill clean closure and wetlands restoration. This process also enables permanent carbon sequestration, generates carbon dioxide removal credits, and enhances soil health while reducing waste volume by 85%.

Impact:

  • Sequesters atmospheric carbon
  • Improves soil health and water conservation
  • Restores wetlands and generates ecological credits
  • Facilitate landfill closure

Agency Partners: Regional Water Quality Control Board, California Coastal Commission

Armstrong Tile Plant

Transforming a 100-Year Old Tile Manufacturing Plant to Powered Data Center Campus

Location: St. Helens, Oregon
Historical Use: Ceiling Tile Production
Restored Use: Data Center
Start Date: 2024
Status: Ongoing
Land: 173 Acres

Challenge: Legacy contamination in lowland areas and complex cleanup posed risks to wetlands and redevelopment.

Solution: Work closely with Oregon DEQ under a Prospective Purchaser Agreement (PPA) to remediate the site, securing liability protection and facilitating efficient cleanup.

Impact:

  • Enables development of a cutting-edge data center campus
  • Brings high-tech jobs and power infrastructure to Columbia County
  • Located near Portland’s data center hub
