The Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers.

Changing Land Surfaces With Retaining Walls

Changing Land Surfaces With Retaining Walls

Retaining walls have become the modern-day structures of choice for us to manipulate the surfaces on which we choose to build our lives. From creating more buildable space on a site, to helping stabilize bridges, they are ubiquitous workhorses that are often easily overlooked. But sometimes they take their inspiration

Soil Savers by the Seashore, and More

Soil Savers by the Seashore, and More

To control erosion in areas of heavy water flows, riprap is often prescribed; however, purchasing, transporting, and setting such large rocks can be quite costly. In addition, depending upon the site, large boulders might not be the most attractive option. Advancements in erosion control blankets, mattresses, and turf reinforcement mats

Constructing an Infiltration Trench Retrofit BMP

In the spring of 2004, an infiltration trench was built on the grounds of Villanova University near Philadelphia, PA. Funded by the Pennsylvania Department of Environmental Protection’s Growing Greener Program and the EPA’s Section 319 Nonpoint Source Pollution Management Program, the trench is the most recent addition to Villanova’s Stormwater

Simplifying the Design of Urban Stormwater Detention Systems

With development occurring at a rapid rate in many parts of the United States and across the globe, stormwater experts are grappling with ways to deal with increased runoff and water-quality problems. More than half the rain that falls on some developed areas may become runoff, and during intense storms,

Improving the Practice of Modeling Urban Hydrology

As stormwater practitioners, if asked, we would all say that we are interested in protecting our water resources and preventing flooding or erosion of downstream properties. We may even be aware that very low levels of urban development (5% to 15% impervious surfaces) have been shown to result in degradation

Volume-Based Hydrology

Volume-Based Hydrology

“If everybody is thinking alike then somebody isn’t thinking.” – General George Patton

Every 20 years or so, urban stormwater practitioners seem to stop and take stock of how we are doing. Sixty years ago, we figured that efficient drainage was the way to do things, using separate stormwater systems

Structural Erosion Control Solutions

Structural Erosion Control Solutions

Nature knows best. This is the premise behind the approach that many contractors have taken on their sites in recent years. It has been a common trend for contractors to use bioengineering techniques or soft-armor erosion control solutions, including erosion control blankets, coir logs, and vegetation alone, to hold soil

Voodoo Hydrology

Voodoo Hydrology

My old friend Dr. Tom Debo, late of Georgia Tech and co-author of our textbook¬†Municipal Stormwater Management, is fond of saying, “I love urban hydrology. They can never prove you are wrong, only inconsistent.” As a principal author of several state and local design manuals and as a past university
