1996: Temporary levee dubbed "Vera's Wall"
Detailed Description
In February 1996, as the Willamette River threatened downtown Portland, Mayor Vera Katz rallied over 1,500 volunteers to build "Vera's Wall". This mile-long, four-foot-high temporary levee, made of 40,000 sandbags, plywood, and jersey barriers, was hastily constructed atop the existing seawall in just 24 hours and successfully held back the floodwaters.
