Diru Creek - between 72nd Avenue East and 80th Street East - has significant channel erosion. As a result, the banks collapse into the creek channel and send a lot of sediment downstream and, eventually, into Clarks Creek and Puget Sound.
This project will use a combination of engineered wood crib structures and plantings to stabilize the banks and slow down the sediment in the creek channel. Buttressing the sides of the creek banks with plantings means they are less likely to collapse into the channel. Installing wood crib structures in the channel will slow sediment allowing the creek to return to a more natural state. This will be especially beneficial during high flow events when a lot of water is flowing through the creek.
