U.S. Corps of Engineers study


The US Army Corps of Engineers has successfully launched their New Start Feasibility Study of the Portland metropolitan area levee system, and as they work through the initial scoping phase, they would like to engage community members in discussing the study process, upcoming milestones, and the preliminary alternatives being developed.

To begin the conversation, we’re working with Corps to hold two open-house style community meetings in December:
Wednesday, December 12, 2018
5:30 p.m. – 7:00 p.m.

Rockwood Public Safety Building
675 NE 181st Ave, Gresham
accessible via TriMet Blue Line & Bus #87 & #25
Thursday, December 13, 2018
5:30 p.m. – 7:00 p.m.
Mult. Co. Drainage District Office

1880 NE Elrod Drive, Portland
accessible via TriMet Bus #70
During both meetings, a representative of the Corps will make some brief remarks around 6:00 p.m. and the Corps and Levee Ready Columbia will have staff on hand to discuss the various activities underway to inform decision-making around the modernization of the levees, including hydraulics and hydrology (flows and flood risk), geotechnical studies of the levees themselves, and the economic risk and consequences posed by various flooding scenarios, as well as the effects on natural and cultural resources of alternatives considered. Most importantly though, the Corps would like to hear the concerns and ideas of community members regarding the Columbia Corridor levee system and managed floodplain.

We hope you will take advantage of this opportunity to come together as a community to provide input on the direction the Corps is heading as they work through the three-year federal feasibility study process, which will lead to a recommendation to Congress for federal investment in addressing the problem areas and vulnerabilities in our local levee and drainage system.

We look forward to seeing you soon!
