The Urban Flood Safety and Water Quality District is requesting Multnomah County voters to approve a property tax increase of 11 cents per $1,000 of assessed property annually over the next 20 years to fund a $150 million bond measure for flood protection improvements. The measure is expected to raise about $7.5 million annually and unlock an additional $100 million in federal funding for the project. The project’s total price tag is estimated to be nearly $300 million, with the remaining balance expected to be provided by Oregon lawmakers. The measure has earned the support of elected leaders, business and environmental groups, and the head of the Port of Portland.
