The Benefits of Engineered Soils

The Benefits of Engineered Soils

Engineered soil: it sounds like a new concept, but one historical record notes it is more than 1,000 years old. In the sixth century AD, a group of ascetic monks left the lush, green mainland of Ireland seeking a new, remote environment to practice their dedication and humility. Braving the

Battling Invasive Species

When William Shakespeare introduced the starling into his play Henry IV more than 400 years ago, he recognized the bird’s moderately annoying qualities by imagining it tormenting its host with the repetition of a single utterance—over and over and over. However, he certainly could have had no concept that his

Mowing for Water Quality

Mowing for Water Quality

Mowers are, literally and figuratively, the cutting edge for managing vegetation. And with new technologies and designs, they offer solutions that are also cost-effective.

Working With Cofferdams and Turbidity Curtains

Cofferdams and turbidity curtains may be neither high tech in performance nor especially exciting in appearance. If they’re made carefully and function the way they are supposed to, they seem, in fact, rather routine. But the work that they make possible is far from routine. They make possible high-tech projects

A Showcase of Innovation

While the British were bemoaning their failed attempt to retake America in 1812, the Commonwealth of Virginia was busy preparing to avert any future invasions. The small town of Lexington, VA, located in a geographically well-protected southwestern corner of the state in the Shenandoah Valley, was deemed a perfect location

Protecting Storm Drains and Inlets From Sediment and Pollutants

Protecting Storm Drains and Inlets From Sediment and Pollutants

The trouble with stormwater runoff is that it travels along the ground surface and over pavement, picking up sediment and other contaminants as it goes. A well-designed surface water runoff collection and drainage system will funnel runoff from relatively large areas into individual collection points such as inlets and drains

Underground Storage and Detention Systems

Underground Storage and Detention Systems

Whether a site is undeveloped, densely developed, or somewhere in between, it can face challenges in detaining stormwater runoff. When aboveground space is at a premium, underground stormwater detention systems are an efficient way to store, detain, or infiltrate stormwater runoff while the ground above is used for parking, parks,
