Low Impact Development (LID) is an innovative stormwater management approach with a basic principle that is modeled after nature: manage rainfall at the source using uniformly distributed decentralized micro-scale controls.

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

PAVEDRAIN LLC
The PaveDrain system is a patented, permeable paving surface designed with the joints between the blocks left open for an unprecedented infiltration rate (i.e., no rocks). Maintenance is accomplished with conventional street vacuuming equipment or the PaveDrain Vac Head. PaveDrain is ADA Compliant, HS-25 load rated, manufactured throughout the

A New Emphasis for Green Infrastructure

A New Emphasis for Green Infrastructure

A few weeks ago I mentioned a plan in Orange County, CA, to capture stormwater by using inflatable dams to slow the flow in a couple of local creeks. The slow-moving water will infiltrate and help replenish the groundwater—the source of much of the county’s drinking water supply—rather than rapidly

New Opportunities and Strategic Models to Cope With Sea Rise

New Opportunities and Strategic Models to Cope With Sea Rise

When perspectives on sea level rise are considered, they might easily take on the glass-half-empty or glass-half-full analogy. For many, the glass is half empty and spells doom for thriving municipalities, helplessly sinking into the sea—reminiscent of the cinematic moment in which Charlton Heston finds the Statue of Liberty submerged

Stormwater Infiltration in Clay Soils

Stormwater Infiltration in Clay Soils

Stormwater runoff from impervious surfaces is causing devastating effects on the landscape of our developing watersheds. We are disrupting the natural hydrological cycle that supports our potable water supplies and natural fauna. Intentional stormwater infiltration can restore that cycle. However, the lack of awareness and the perceived lack of data

NITEHAWK SWEEPERS
The next generation Osprey II is engineered to perform in the most diverse operating environments. Built on a low-profile conventional chassis, this sweeper can excel in any location. Thirty-five years of inspired design and field testing have culminated in the best-in-class sweeping performance of the Osprey II. The advanced

Twenty-Year Engineering Assessment of an LID Facility in Boulder, CO

This article provides a summary of the evolution of small stormwater control facilities constructed approximately 20 years ago using low impact development (LID) principles at a 10,000-square-foot office site in Boulder, CO. This project was undertaken to demonstrate how surface stormwater controls designed as multifunctional systems can support regionally appropriate
