At BioEngineering Associates, we specialize in preventing and reversing land loss caused by flowing water, whether it be along a river or streambank, a saline estuary or an erosive gully tearing through a mountain meadow or forested hillside. Using the centuries-old art and science of "bioengineering," we build stabilizing structures whose primary components are living plants. With these techniques, we can stop land loss and recapture and revegetate eroded areas using the hydraulic properties of live, flexible structures.  For many of our clients, such as Napa and Sonoma County wineries where visitors and guests play an important role, the natural and beautiful appearance of our bioengineered solutions is an important factor. Our projects have received the highest awards and recognition at the state, national and international levels.
