Oregon's state capitol building could soon undergo a massive renovation. It's a project so big, lawmakers would have to use a temporary capitol for more than three years.
Senior project manager Tary Carlson says the idea is to help the Depression-era capitol building withstand a major earthquake.
"When this was built 76 years ago, they did not design for lateral forces of a seismic event such as a Cascadia Subduction Zone," Carlson says.
And so what would be left if the Big One hits?
"A pile of rubble," Carlson says.
