September 2012

Otak served as a Silver Sponsor of the 2012 Sustainable Stormwater Symposium held in Portland, Oregon, on September 19 and 20. The symposium was organized by the American Society of Civil Engineers – Environment and Water Resources Group at the World Trade Center in downtown Portland and was enjoyed by almost 150 attendees. Keynote speakers included Robert Pitt, PhD, PE, who summarized his research findings around design of green infrastructure; Scott Wells, PhD, PE, who shared cautions about interpreting and reporting modeling data; and Tracy Tackett, PE, who presented the history and future of Green Stormwater Infrastructure in the City of Seattle.

Other speakers covered topics including challenges in LID infrastructure design, best practices for facility maintenance, and innovative UIC retrofit projects. Unique presentations covered modeling of CSO geysers, partnering with school children to steward bioretention facilities, and the challenges of applying basic stormwater management techniques to an Engineers Without Borders project in Honduras.

Presentations will be available on the symposium website at:

The first day ended with a poster session happy hour. Ashley Cantlon, PE, LEED AP BD+C, presented a poster with a cost comparison between conventional stormwater treatment techniques and the constructed alternative using LIDA facilities at Burnham Green Street in Tigard, Oregon. The second day included a morning session of presentations and concluded with a “Bike-BMP-n-Brew” tour of local LID facilities in the downtown Portland area.

The symposium was a wonderful opportunity to share knowledge of the growing field of sustainable stormwater design. We are looking forward to participating in the next symposium!
