Columbia River flood prevention measure passing in early results

A measure to upgrade the aging flood prevention infrastructure along the Oregon side of the Columbia River was passing in early May 21 election returns.

The Urban Flood Safety and Water Quality District bond measure was ahead 67% to 33% in results released at 10 p.m. Results will be updated in coming hours and days. Ballots postmarked by 8 p.m. on May 21 will be counted if received within seven days.

The measure will raise $150 million to match $100 million in federal funds to upgrade levees, pump station and other infrastructure. Much of the system has not been improved since the 1948 flood that destroyed the former city of Vanport.
