Permeable paving is a range of sustainable materials and techniques for permeable pavements with a base and subbase that allow the movement of stormwater through the surface. In addition to reducing runoff, this effectively traps suspended solids and filters pollutants from the water.
This article discusses a novel approach of using a sand lens to convey the stored volume of runoff gradually into the deeper layers of the soil, or to the water table, to overcome some of the design challenges resulting from clayey soils.
By some estimates, more than 1,400 stormwater utilities now exist in the US, but each time a community attempts to set one up, it’s a new process all over again—introducing residents and potential ratepayers to the concept, enlisting the support of elected officials, setting up a rate structure. And each

Situated on more than 87,000 acres adjacent to the Puget Sound, Joint Base Lewis-McChord (JBLM), WA, is one of the largest military bases in the country and is considered to be one of the premier military installations on the West Coast by the US Department of Defense (DOD). JBLM is
Permeable pavement is taking center stage now as erosion control and stormwater green infrastructure projects aim to reduce runoff and improve water quality.
Stopping Nonpoint-Source Pollution
In Columbia, MO, the Public Works Department received a Clean Water Act 319 grant for stormwater improvements to reduce nonpoint-source pollution into the creeks and streams.

“We run our sweepers every day of the week except the weekend, for nine to nine-and-a-half months of the year—even some days of December when the weather is mild. We don’t put water in the tank when it might freeze,” says Dale Chumley, chief of stormwater for the city of
