Despite increasing implementation of green infrastructure for stormwater management, information on its design, implementation, operation, and performance is limited. In July, the Science Policy Exchange, in cooperation with Syracuse University, released the report Green Infrastructure: Lessons from Science and Practice. The report is intended to help readers understand the strengths and limitations of green infrastructure. […]
An article by Mark Walker, director of business development for Kuert Concrete, detailing the differences between pervious, permeable, and porous pavers.
On Nov. 9, the Tennessee Healthy Watershed Initiative announced $750,000 for nine watershed improvement projects. Knox County was awarded $95,400 in funding to complete Phase 2 of the Harrell Road Stormwater Demonstration Park. The 6-ha (15-ac) park is on a previously abandoned tract. A wetland will filter runoff, and the park will contain other stormwater […]
On Dec. 12, Imagine H2O announced the finalists for its 2012 water startups prize. PaveDrain, LLC is among the early revenue track finalists. The company offers a permeable-pavement option that utilizes arched blocks. According to PaveDrain, the arched shape improves structural integrity and maximizes stormwater capacity. Imagine H2O inspires and empowers individuals and emerging companies […]
On April 18, high school students in Yakima, Wash., helped collect runoff samples from a low-impact development demonstration project. The project — funded in part by a grant from the Washington State Department of Ecology — compares pervious asphalt, pervious concrete, and permeable pavers. All three demonstrations have a layer of crushed stone or sand […]
Tom Ballestero and Rob Roseen, University of New Hampshire Stormwater Center Due to the need for improved stormwater management, the application of porous pavements is increasing dramatically in northern areas with cold climates. Yet, there are persistent misconceptions about these systems, in particular with regard to cold climate performance. Permeable pavement infiltration is not negatively affected […]
