Course Title: WORKSHOP - Low Impact Development: Sustainable Stormwater Management Design to Improve On-site Flow Control and Water Quality Treatment
Course ID: GBS-300 Workshop
Status: OPEN
Date(s): August 19, 2020: 8:30am - 2:30pm
Location: Live Remote Attendance-- USA

Shoreline / Live-stream Remote, WA
Instructor: Curtis Hinman
Tuition: $0



This partial-day workshop provides a brief overview of low-impact development approaches and resources for building industry professionals and will include a classroom presentation and field activities. Low Impact Development (LID) is an alternative, systems-level approach to conventional stormwater management. Critical for the Pacific Northwest where water quality and salmon habitat protection are key issues, LID offers opportunities for sustainable site design and water efficiency.  The classroom and field portions of the course will be livestreamed to meet all safety requirements for covid-19.  The course is fully interactive with live real-time instruction, questions, activities, etc.

Curtis Hinman is a Senior Stormwater Scientist based in Bellingham, Washington. Mr. Hinman has led academic programs and managed a diverse portfolio of projects ranging from bioretention media research, green stormwater infrastructure (GSI) design and statewide and national LID training programs. His most current research focused on developing high-performance plant-soil systems for stormwater filtration. Prior to managing media filter research and LID education programs at Herrera Environmental Consultants, Curtis was faculty with Washington State University (WSU) Extension and Department of Biological Systems Engineering. As the University’s Green Stormwater Infrastructure Specialist he co-designed and was lead scientist for the WSU Low Impact Development (LID) Research Program which is one of the largest LID research facilities in the U.S. Mr. Hinman is the author of the “Low Impact Development Technical Guidance Manual for Puget Sound” and the “Rain Garden Handbook for Western Washington”. Curtis also serves on several American Society of Civil Engineers committees developing national guidelines for green infrastructure and bioretention systems.
