Both public-side and lot-­level (private-­side) measures are important for effective mitigation of urban flood risk

“Basement flooding is one of the most substantial drivers of natural disaster losses in Canada,” states Dan Sandink. “Our report explores legal tools that could be used to require private property owners in existing developments to better manage excessive rainwater and protect against flood risk. We examine the legal implications of applying these tools in the Canadian municipal context.”

News about Chesapeake Bay, USA: Local municipalities seek solutions that are both effective and not overwhelmingly costly

Caught in the middle of the stormwater runoff issue are “urbanized” municipalities, including most boroughs and townships in eastern Cumberland County in Pennsylvania, which are required to reduce stormwater pollution by 60 percent by 2025. There are ways to mitigate the cost through intermunicipal cooperation, Kirk Stoner said, and the county has organized a working group involving all the municipalities required to complete a pollution reduction plan.

VIDEO – Slow the Flow: Make Your Landscape Act Like a Sponge

The State of California has released a film series to bring to life simple practices that individuals and communities can do to become stewards of their watersheds and slow the flow of stormwater from homes and businesses when the rain returns. "When much of California is facing drought and limited water supplies, capturing and reusing every drop of water will not only be clever, but crucial," wrote Paula Luu.

Regulating Rainfall in the United States: Proposed EPA Stormwater Rule

"The projected rulemaking addresses a number of key areas of action, particularly the implementation of a specific on-site performance standard in new and redeveloped sites as projects are built. This include establishing a single set of stormwater requirements for all municipal separate sewer systems," writes Art Haddaway.

“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.
