Capital Regional District hosts workshop on Puget Sound experience related to "Low Impact Development"
In August 2009 the CRD hosted a two-day technical workshop on Low Impact Development (LID) rainwater management techniques. The workshop was organized in collaboration with Washington State University Pierce County Extension. The workshop covered these topics:
- Introduction to LID
- Bioretention basics – types, basic structures and functions, trends in applications and functions, design examples
- Permeable pavements – types, trends in applications and functions, performance, design examples
- LID strategies for reducing combined sewer overflows
- Bioretention soil mix
- Hydraulic modeling and facility sizing – continuous vs. event-based modeling, effects of soils with low infiltration rates, available modeling tools
- Water quality treatments – mechanisms and performance
- Case studies in the Pacific Northwest
- Tour of LID techniques at UVic
“The workshop provided participants with the current state of knowledge and in-depth technical information needed to properly design, build, inspect, and maintain bioretention and permeable pavement facilities,” reports Brianne Czypyha, Environmental Science Officer with the CRD.
