The Mill Creek Flood Control Project was completed in 1942 and included levees along the improved Mill Creek channel to provide flood protection for the City of Walla Walla. Currently, the Mill Creek Project levees fail to comply with U.S. Army Corps of Engineers vegetation standards used to ensure reliability, resiliency and operability of levee, floodwall, and dam projects nationwide.
Non-compliant vegetation on levees blocks visibility for inspections, access for maintenance, hinders flood fighting, and adds uncertainty to structural performance and reliability, which increases risk. The inability to inspect, maintain or flood fight could contribute to a breach or delay emergency response.
Over many years, the Corps has been trying to formulate a viable solution to address levee-maintenance issues at Mill Creek that has minimal impact on the aesthetic quality of the popular trails. Because of funding priorities and lack of staffing, we were unable to make much progress in this area. During the time that passed, the vegetation grew out of control and encroached into the levee maintenance zone.
In the Corps’ view of things, not knowing if our levees are in good condition and ready to perform during a flood is an unacceptable risk to public safety. It is not an option to continue to allow non-compliant vegetation to potentially put lives at risk.
We are developing a plan to ensure our levees are properly maintained to perform as designed – Ensuring our levees meet required safety standards will be a multiple-year effort. The following tasks need to occur as funding becomes available: clear the maintenance zone, remove stumps, repair the levee structure and plant grasses.
The plan will include an environmental assessment, with opportunity for the public to comment on the plan, likely during the May-June timeframe.
There are a lot of details we don’t yet know, but we will continue to keep the public informed as we move forward to make our levees sa
