Revegetating After a Wildfire

It was in June 2013 that the 3,200-acre Royal Gorge fire broke out near Cañon City, CO, situated about 45 miles southwest of Colorado Springs. The wildfire destroyed almost everything in its path (48 out of 52 structures in Royal Gorge Park were lost), although surprisingly it spared the Royal

Project Profile: Site Sampling Tools

Geophysical surveys can be the bedrock (pardon the pun) of today’s environmental projects, from locating abandoned underground storage tanks (USTs) and utilities, to complex mapping of geology in remedial investigations, to finding landfill boundaries and other buried unknown problems. In the past few decades, a variety of non-destructive testing methods

The Waxed-Paper Doughnut That’s Saving Trees

Desertification is a growing problem—or perhaps more accurately a non-growing problem—in many parts of the world. Planting trees, or afforestation, is one way to combat desertification, but it works only if the trees survive; in many areas the survival rate has been dismal. As this article points out, the poor-quality

Integrating Land-Use Changes for Future Stormwater Projects

In early July 2013, 2 inches of rain fell within a 45-minute period at the city-owned Lebanon Municipal Airport in Lebanon, NH. This storm created devastation for the city and the airport, with multiple slope failures and roadway washouts. In all, 3.47 inches of rain fell during the 10-year storm

Foliar Rainfall Retention

Foliar Rainfall Retention

Trees and forest systems play an important role in the water cycle by intercepting rainfall and regulating water flow to the soil for more efficient stormwater infiltration. Traditional urban development practices have reduced the function of these systems by eliminating the vertical structure (tree canopy cover), removing existing ground cover
