Rainwater Capture: Design

"Understand How Water Reaches the Stream and Design for Interflow", urges Department of Fisheries and Oceans

“Interflow is often the dominant drainage path in glaciated landscapes of British Columbia. Even undeveloped sites founded on till and bedrock rarely show overland flow because of interflow pathways. The lesson is that the interflow system is an incredibly important and yet fragile component of a watershed. It is critical for maintaining stream health and our fishery resource,” states Al Jonsson of DFO.

Shifting from Gray to Green: Curbing Polluted Stormwater and Creating Communities in the Pacific Northwest

“Ailing Northwest rivers and lakes face death not so much by a thousand cuts as by a thousand rainstorms, each flushing filthy runoff into our region’s environmentally and economically important waterways. But work is underway to change this. Low-impact development treats larger volumes of water, is cheaper to maintain, boosts propety values, creates wildlife habitat, and reduces greenhouse gases,” writes Lisa Stiffler.

United States EPA Stormwater Rules should Acknowledge Benefits of Urbanism

“Redevelopment of previously developed land can lead to the net improvements in watershed health that we need. Redevelopment triggers restoration activities of our existing built environment. Watershed and sub-watershed analysis, integrated with regional planning and local regulations, should be at the heart of new stormwater regulations,” states John Norquist.

Bigger Pipes or Greener Communities: A Hydrological Assessment of using Low Impact Development to Mitigate Future Flooding

“Climate change significantly raises the risk of rain-generated floods and infrastructure failure. To maintain current levels of service, drainage infrastructure will need to be modified and upgraded. A key challenge is that for many communities, it will be prohibitively costly to rely on conventional engineered solutions,” states Chris Jensen.
