Bioretention Summit:

Bioretention design, construction, and maintenance continue to evolve as the practice has become the most popular small-site stormwater control measure in much of the United States. Design standards, construction specifications, and maintenance plans for bioretention often lag behind what recent applied and lab research has discovered. The purpose of this training is to deliver the most up-to-date research-based information that will lead to perhaps dramatic improvements in how bioretention cells are credited by regulators, designed by engineers and landscape architects, and built and maintained by contractors and maintenance personnel.

The training will be from 8:00am to 5:00pm on Day 1 (registration at 8am with class starting at 8:30), and 8:00am to 12:00pm on Day 2. Powerpoints from the May 15-16 workshop can be viewed by clicking this link.

Below is a sampling of some of the Issues to be discussed.

  • How can fill media be specified to achieve low nutrient concentrations and loads
  • Adjusting credit awarded to bioretention installed in sandier soil environments (like the coastal plain and barrier islands)
  • How bioretention cells can be designed to capture larger fractions of water to meet infiltration and evapotranspiration goals
  • The benefits of using an internal water storage layer to enhance performance in many soil types
  • How bioretention designs can be tailored per specific target pollutants, including emerging pollutants such as thermal loads and pathogens
  • How can bioretention construction be improved to increase infiltration?
  • Are bioretention devices really low maintenance?

The training is unique because it brings together three prominent bioretention researchers to answer these and more questions. In fact, registrants are encouraged to submit questions in advance to the instructors via the website registration form so that they may be addressed during the workshop.

Continuing Education: Up to 11 Professional Development Hours (PDHs) may be available for professional engineers and land surveyors, and landscape architects. Attendees may appeal to their respective boards to obtain professional education credits.

Lead Presenters:

boxBill Hunt, Ph.D., P.E.

Dr. William F. Hunt is an Associate Professor and Extension Specialist in the Biological and Agricultural Engineering Department at NC State University. As director of the Stormwater Engineering Group, he is actively involved with Best Management Practices (BMP) demonstration, applied research, and training. Bill also likes public venues in which to croon to the delight or dismay of many.

boxAllen P. Davis, Ph.D., PE

Allen Davis' focus at the University of Maryland Department of Civil and Environmental Engineering is on water quality and physicochemical treatment processes, urban storm water quality and the concept of Low Impact Development, fundamental and applied research on practices such as bioretention, grass swales, and other technologies, He provides quantitative information on performance efficiency and design improvements. Dr. Davis holds a B.S. , a M.C.E. and a Ph.D. from the University of Delaware.

boxRobert G. Traver, Ph.D., PE

Dr. Traver is an Associate Professor at Villanova University and Director of Villanova Urban Stormwater Partnership. Dr. Traver has been the main force in creating a Stormwater Best Management Practice Demonstration and Research Park on the Villanova Campus. Research is underway on a Stormwater Wetland, and four infiltration BMP’s. To enable continuing study into advancing research in these areas, Dr. Traver founded the Villanova Urban Stormwater Partnership, and serves as its director.
