Runoff First Flush: Fact or Fiction?
Studies in Salt Lake County, Utah, help determine whether first flush exists in the region and the implications for choosing stormwater treatment systems.

More rational decisions on treatment system selection and design would occur if stormwater engineers adopted a concept long established in other branches of engineering: unit processes and unit operations
The briefing report on Multi-Functional Urban Green Infrastructure is aimed at policy-makers and practitioners and discusses the drivers and barriers to increasing green infrastructure provision in towns and cities.
Stomwater Treatment by Dr. Gary Minton – cover (198×270)
The distinction between the “engineered filter” and “nature’s filter” has blurred. The underdrain system is soil rather than pipes. The filter media is the native soil. But it is becoming more common to specify engineered media.
Stormwater Management: Using trees and structural soils – manual cover (360p)
Researchers know that urban forests, like rural forest land, can play a pivotal role in rainwater/stormwater mitigation. Structural soil reservoirs may provide new opportunities for meeting engineering, environmental, and greenspace management needs in urban areas.
In 2005 Bruce Ferguson completed the first comprehensive guide to porous pavements, which have been called “the holy grail of environmental site design” and “potentially the biggest development in urban watersheds since the invention of the automobile.”

Permeable pavement is one of four recommended low-impact development (LID) methods promoted in an LID manual being developed by Sarasota County, Florida, and the Southwest Florida Water Management District.
In the January 2009 issue of Stormwater magazine, writer Christopher Estes presents monitoring data for three sites in the North Carolina Piedmont that demonstrate the success of rainwater/stormwater infiltation in clay soils.
The U.S. Environmental Protection Agency's stormwater program — which oversees stormwater discharged by cities, industries, and construction activities — needs radical changes if it is to improve the quality of the nation’s waters, says a new report from the National Research Council. It recommends that permits be based on watershed boundaries, and the program focus on the impact of increased water volume rather than chemical pollutants.
In 2004 the Occidental Arts & Ecology Center (OAEC) in Sonoma County established the WATER Institute (Watershed Advocacy, Training, Education & Research) to promote an understanding of the importance of healthy watersheds to healthy communities. OAEC’s WATER Institute builds upon their many years of regional watershed research, restoration, advocacy, community organizing, and activism.
