When ZGF Architects presented us with a proposal to build a nine-acre wooden roof over PDX’s new main terminal, we responded with a question: Can we source 2.6 million board-feet of Douglas fir in a way that is better for the land and better for our local communities?
Together, the team came up with a set of goals:
- All the wood would come from Oregon and Washington forests located less than 300 miles from PDX.
- We would source as much timber as we could from small landowners, community forests, and sovereign tribal lands, prioritizing landowners who were working to restore forest ecosystems.
- Inspired by “farm to table” cuisine, we tried to trace as much of the wood as possible from forest to frame, something few big construction projects have ever tried.
No one—in the United States, in fact!—had done this before at the same scale. It took two years and many, many phone calls to build a network of Pacific Northwest foresters, mill owners, brokers, truckers, and construction firms who could join our quest to trace wood from forest to frame.
Here’s how we did it
Traditionally, timber mills contract with forest landowners to clear-cut timber from large tracts of land. (The landowners also plant saplings to replace the 30-to-80-year-old trees they harvest.) Mills get logs from dozens of forests, and all that timber goes into massive piles before it’s cut into boards and dried in kilns.
The system is efficient. There’s little waste. However, by the time the lumber leaves the mill, there's no way to tell which forest it came from.
Three-fourths of the timber we sourced went above and beyond federal standards for ecological forestry. Some of the forest caretakers we worked with even thinned their trees with precision-cutting machines or cleared small (1- to 6-acre) plots. Methods like these give the remaining trees better access to water and light, increase biodiversity, and make the forests more resistant to wildfire and drought.
The mills that bought our forest-to-frame logs agreed to store and cut the wood separately from the rest of their supply—no small effort for efficient, fast-moving operations. Truckers then brought the boards to PDX’s fabricator and construction partners, who carefully labeled and stored all the wood destined for PDX’s roof and made sure it never mingled with other materials.
In the end, 100% of the wood in PDX’s new roof came from a 300-mile radius, and we can trace 40% of the timber back to its forest of origin. Our hope is that our efforts will make it easier for other major building projects to follow suit.
Most of all, we are grateful to the hundreds of people who cared for this wood every step of the way.

Tom Strong - Chief Executive Officer, Skokomish Indian Tribe, Skokomish Washington
"We're foresters in that we're stewards," says Tom Strong, Chief Executive Officer of the Skokomish Indian Tribe, which manages 2,000 acres of Washington forests for its 800 tribal members. "We're not cutting and planting, seeking to develop our lands into a commodity. Instead, we're doing it to restore the forest."
Over the past 100 years, the two dams on the North Fork Skokomish River have had a major impact on the entire ecosystem of Skokomish land. "We want to restore the entire Hood Canal watershed," Tom says. The forests are just one part.
Selling wood from Douglas fir trees the tribe selectively thinned will help fund this restoration. "We don't have an endless amount of money," Tom says. "But we would like to think we've got an endless amount of time."
Ben Hayes - Co-owner, Hyla Woods, Cherry Grove, Oregon
Ben Hayes is a sixth-generation forester who manages Hyla Woods, outside Cherry Grove, Oregon, with his father, Peter. He is also a sustainable-forestry consultant. At Hyla Woods, the Hayes experiment with selective thinning and patch cutting, instead of clear-cutting, to foster diversity of tree species, ages, and sizes.
"When you look 100 years out, having greater complexity in terms of species and the structure of the forest, you can increase the forest's resilience in the face of extreme weather and drought," he says.
"We're working toward a model of forestry that you could practice for the perpetual future,” Ben says. “It's a model that lifts up both rural and urban communities and the ecosystems we rely on."
Richard and Ann Hanschu - Owners, Doneen, Forest Grove, Oregon
Ann Hanschu's father first bought land outside Forest Grove, Oregon, in 1956. Ann grew up trailing her father around the forest, learning from him. The Hanschus now have three children, four grandchildren, and five great-grandchildren.
Richard says, "We're planting trees that our grandchildren will see the profits from — not even our children. It's long-range thinking."
"A lot of the timber is older,” Ann adds. “We're laddering it with trees of different age groups — some 30-40 years old, some 10-20 years old — so the land can continue to produce a sustainable amount of wood."
Herman Flamenco - Central Cascades Conservation Forester, The Nature Conservancy, Cle Elum, Washington
"We know historically that the stands we're working on were overstocked," says Herman Flamenco, Central Cascades conservation forester for the Nature Conservancy, of the 50,000 acres outside Cle Elum, Washington, the organization manages. Thinning the trees welcomes in light and biodiversity.
Some loggers in the region worry that this low-impact approach to forestry yields less lumber, and less profit, than clear-cutting. One local outfit took on this labor-intensive challenge, selectively harvesting Doug fir trees from steep slopes.
"Western Washington is wetter. In our dry climate, there's less moisture and increased fire risk," Herman says. "As we look at climate change, it's just going to get dryer. We want to make sure we can keep our forests around."
In the 1950s, back when people wore fancy hats to the airport, PDX’s main terminal had brown terrazzo floors.
By the 1970s, blue carpet sporting the old Port of Portland logo replaced the terrazzo. The airport was so concerned about keeping the carpet clean that we banned gum-chewing indoors.
In the 1980s, PDX replaced the ski-chalet paneling in the Clocktower Plaza with high ceilings and skylights, but kept the blue carpet.
SRG Partnership, a Portland-based architecture firm, designed the pattern for the now-iconic carpet on the layout of the airport runways.
