Today marks 75 years since a deadly flood devastated parts of what is now north Portland.
15 people were killed and 18,000 were left homeless in the Vanport flood.
Vanport was built along the Columbia River in 1942 as a housing project for shipbuilders and their families during World War II.
Vanport became Oregon's second-largest and most diverse city, with more than 40,000 residents.
Portland Mayor Ted Wheeler declared today "Vanport Day of Remembrance" and encouraged residents to remember and honor the lives affected, learn from their experiences, and strive to create a more inclusive and resilient city for all.
Portland International Raceway and Delta Park now sit on the land that Vanport once occupied.
President Harry S. Truman flew to Portland on June 11, 1948, to examine the damage.
Oregon Governor Tina Kotek issued a tweet Tuesday afternoon saying “Today we honor the history and resilience of Vanport on the 75th anniversary of the devastating flood that forever changed lives. Let us stand together to ensure the stories are told and we learn from the past.”
