cbec eco engineering, a Verdantas Company’s Post

A recent visit to the Lower Yuba River Lower Long Bar Restoration Project site revealed extensive vegetation recruitment two years after construction in 2022. This roughly 62-acre gravel mine property had a history of massive aggradation of hydraulic mining sediment during the late 1800s and early 1900s, followed by rapid channel incision. This caused the floodplain to be disconnected from the river at lower flows, becoming largely inaccessible to rearing juvenile salmonids. cbec services consisted of site surveys and analysis, concept through construction planset design development, as well as construction observation and post-project monitoring. Our designs included the removal of more than 350,000 cubic yards of gravel to lower the floodplain, and the addition of a side channel to increase seasonal and perennial salmonid rearing habitat. This regular inundation also stimulated riparian vegetation recruitment, which is flourishing in this video.
