State Heritage Tree To Be Dedicated Friday During Vanport Mosaic Festival (Photo) - 05/26/26

(Portland, Oregon) The Travel Information Council and its volunteer Oregon Heritage Tree Committee invite the public to participate in the induction of the Vanport Cottonwoods into the Oregon Heritage Tree Program during the Vanport Mosaic Festival. The event will take place on Friday, May 29 at 10 a.m. at the trees, which can be accessed from the parking lot at 1810 N Broadacre Rd, Portland OR 97217 near the entrance to the Portland International Raceway.

The Vanport Mosaic Festival is a 10-day event that amplifies, honors, and preserves the silenced histories that surround us in order to understand our present, and create a future where we all belong.

Vanport was among the largest wartime housing projects in the United States, housing over 40,000 people at its peak during World War II. From 1942 to 1948 it was also the second largest city in Oregon. It was built in one year to house workers and families in war industries, primarily at the Vancouver and Portland shipyards. Vanport was wiped out by Columbia River floodwaters on Memorial Day weekend, May 30, 1948.

Today, there are few remnants of this community on the landscape. Thanks to a collaboration between Nidus Consulting, Outdoor History Consulting, and the Vanport Placemarking Project, several cottonwood trees have been identified that likely survived the Vanport Flood. The team utilized aerial photos from the City of Portland’s Archives to track images of the same stands of trees in the same locations over decades to provide strong evidence.

Oregon Heritage Tree Committee Chair Dave Hedberg emphasizes how the cottonwoods aid us in connecting to Oregon’s past. “These trees were likely younger trees growing among clusters of larger trees during the time of Vanport. For over 75 years, they have grown while the landscape transformed. Imagine what these trees have witnessed: construction equipment building a city from farmlands, workers leaving for shifts at the shipyards, kids playing in and around the banks of the slough, and the violent and sudden destruction of the 1948 flood.”

Vanport is also significant because of diverse populations who called it home, particularly Black and Indigenous communities. When displaced after the flood, many Vanport residents remained in Portland and have helped shape the culture and history of the city. 

Vanport Placemarking Project helped prepare the nomination for the heritage trees. Their goal is to install signage in strategic locations to highlight Vanport’s history and share how it has shaped and impacted the environment and people. Thomas Meinzen, operations director of Vanport Placemarking Project notes, “As living monuments, these cottonwoods help anchor the stories of Vanport survivors and their families to this place.”

The Oregon Heritage Tree Program is the first state-sponsored heritage tree program in the country. It was established in 1995 to increase public awareness of the important contribution of trees to Oregon’s history and the significant role they play in the quality of our daily life. The program is administered by the Oregon Travel Information Council and a committee of dedicated volunteers from across the state.
