Tag: stormwater pond

A stormwater management pond is an artificial pond that is designed to collect and retain urban stormwater.[1] They are frequently built into urban areas in North America to also retain sediments and other materials.
In urban areas, impervious surfaces (roofs, roads) reduce the time spent by rainfall before entering into the stormwater drainage system. If left unchecked, this will cause widespread flooding downstream.

Stopping Erosion Flat Out

Stopping Erosion Flat Out

Twenty years ago my brother and I started out as small excavating and general contractors,” says Chauncey Webster, president of East Coast Green Inc., in St. Thomas, PA. “Gradually we leaned more and more toward erosion control work.”

Temporary Erosion Control  Best Management Practices – Installation & Implementation

Temporary Erosion Control Best Management Practices – Installation & Implementation

When designing your Stormwater Pollution Prevention Plan (SWPPP) there are several temporary best management practices to pick from, but picking the right one can be tricky. Between considering site conditions, performance goals, installation methods, and regulations…how can you assess, select, and install the right BMP for your site?

Integrating Land-Use Changes for Future Stormwater Projects

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

Street Sweeping With the Best

“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

Madison, Wisconsin: Capital Stormwater Management

Two entities are the major players for stormwater projects—green and gray—in Madison. One of those players is the city itself, which as of 2014 had a population more than 245,000. The other is the University of Wisconsin’s (UW’s) main branch. Its flagship campus of the UW system covers 936 acres

Stormwater Performance Assessment: Inspection, Testing, and Monitoring

Even the best designed stormwater treatment practices decline in performance over time. Regular assessment of the treatment’s performance (in relation to its goal) is critical for quantifying and qualifying its current performance, necessary maintenance, and future expectations. But…what is the best assessment method for your treatment? And, how can you

Airport Flood Control Considerations

Airport Flood Control Considerations

Think of flood control and the image of a raging river may come to mind. But small floods—from creeks overflowing their banks or urban stormwater runoff in areas that don’t have adequate drainage—also cause problems. Fortunately, there are some effective products that deliver the solutions needed to prevent or control
