BioEngineering Associates, Inc. is an engineering contractor specializing in watershed restoration. Using our living plant based technology to prevent and repair erosion damage, we restore damaged rivers and stream banks, flood plains and terraces, erosion gullies and landslides. We employ the centuries old technology called bioengineering. In its purest form this technology builds stabilizing structures out of live plants that offers the natural solutions which have now become regulatory standards. We have received state, national and international awards. For our work in controlling non point source water pollution we received the United States Environmental Protection Agency’s prestigious Hal Wise Award.

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.
