Online Open House: No. 1 Canyon Flood Debris Basins

Located immediately west of Wenatchee, the No. 1 Canyon basin sits along the east slopes of the Cascade Mountain foothills. The canyon’s natural drainage system has a long history of experiencing occasional heavy runoff – and even debris and mud flows. But these flows, typically caused by high intensity storms, have grown more destructive as the Wenatchee community’s urban area has grown.

A consultant for the Chelan County Flood Control Zone District is designing a series of four flood debris basins on 21 acres at the end of No. 1 Canyon Road that will capture and release flood flows downstream in an attempt to minimize future damage. When built in summer 2021, the project will allow sediment, woody debris, rocks and other materials to be deposited within the basins and overflow channels before the material is conveyed downstream and, potentially, causes a system failure.

Typically, the county plans an open house to introduce the public to the project and answer any questions. Because of COVID-19 concerns, we created an online open house that includes project information and an opportunity to submit comments by Sept. 30, 2020. Please go to the online open house to learn more about this important project. And sign up for project updates that will be emailed directly to you.
