What’s at Risk

Every year, there’s a significant chance we’ll experience a major flood on the Columbia River in the Portland metro area.

A 27-mile levee system helps reduce the risk of flooding along the Columbia from North Portland through Gresham, Fairview, and Troutdale.

But no levee can eliminate all risk, and the federal government has deemed our levees inadequate to protect lives and for residents and business owners in the area to qualify for affordable flood insurance.
