BioEngineering Associates are specialists in preventing and reversing land loss caused by flowing water, whether it is along a river or streambank, a saline estuary or an erosion gully tearing through a mountain meadow or forested hillside. Using this centuries old art and science of time tested techniques called bioengineering we build stabilizing structures whose primary components are living plants. With these techniques we not only stop land loss but often can recapture, rebuild and revegetate eroded areas using the hydraulic properties of our flexible living 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 level.
