Don Gray, M.ASCE, recently received the the Ralph A.Peck Award.

More and more regulators and resource agencies are asking for or requiring project plans that “design with nature”. 


Are you interested in incorporating Biotechnical (Bioengineering) and Environmentally Sensitive Methods into the work you are designing or reviewing?  Looking for more information? Reviewing case studies, especially those that have “passed the test of time”, are one of the best ways to determine efficacy, appropriateness and reliability of Bioengineering Techniques.  

John McCullah, Professor Emeritus Don Gray, and Wendi Gold Smith recently released Bioengineering Case Studies Sustainable Stream Bank and Slope Solutions. 

Don Gray and John have collaborated on projects and design guidance manuals for 20 years.Their collaborations thru the years have been synergistic – combining Don’s knowledge of engineering practices and geotechnical soil stability with John’s extensive bioengineering project experience has resulted in the “perfect wave” of guidance for effective and practical applicationof Biotechnical Techniques.

Don Gray, M.ASCE, recently received the Ralph A. Peck Award for developing new methodologies, design recommendations, and procedures for environmentally friendly biostabilization techniques. Professor emeritus of Civil and Environmental Engineering at the University of Michigan, Gray has made major and long-standing contributions in the broader field of geoenvironmental engineering, soil behavior, and soil reinforcement, and for decades he has carried out research on soil reinforcement and the influence of woody vegetation on the stability of slopes. Don’t miss this opportunity to view Don’s 2015 Ralph A. Peck Award lecture at IFCEE 2015 San Antonio, Texas.

Don and John also collaborated and co-authored the (2005) NCHRP Report 544, Environmentally- Sensitive Channel and Bank Protection Methods (AKA E-SenSS) and BioDraw 3.0. These design guidance documents are provided on CD with, not only design criteria, construction standards, but also AutoCad (.dwg files) and/or Microstation (.dgn files).
