Culverts are among the most common pieces of stormwater and roadway infrastructure in the United States, yet they often receive far less attention than they deserve. When properly sized and maintained, culverts allow water to move freely beneath roads, driveways, trails, and rail lines. When they ar…

The Adirondack Watershed Institute, often referred to as AWI, has become one of the most important environmental organizations working to protect New York’s lakes, rivers, and wetlands. Based at Paul Smith’s College in the northern Adirondacks, AWI blends scientific research, on-the-grou…

The Municipal Separate Storm Sewer System (MS4) program is one of the cornerstones of stormwater regulation in the United States. Established under the federal Clean Water Act and administered through the National Pollutant Discharge Elimination System (NPDES), the MS4 program requires municipalitie…

For much of the last century, stormwater management followed a simple philosophy: collect runoff as quickly as possible and move it downstream through pipes, ditches, culverts, and channels. Success was often measured by how rapidly water could be removed from streets and developed areas. That appro…

Waterfront properties are among a community's most valuable and desirable lands. They offer scenic views, recreational opportunities, and direct access to lakes, rivers, ponds, and coastal waters. Yet the landscaping practices commonly used to maintain these properties can unintentionally become…

When most people think about stormwater pollution, they think of sediment, nutrients, oils, trash, or road salt. However, heat itself can be a pollutant. Thermal pollution occurs when stormwater runoff becomes significantly warmer than the natural receiving waters it eventually enters. Elevated wate…

Most storm drain inlets quietly collect and convey runoff without attracting much attention from the public. To many residents, a storm drain is simply another opening in the curb or grate in the pavement. What many people do not realize, however, is that storm drains in most municipalities discharg…

In stormwater management, some of the most serious failures begin as subtle warning signs that are easy to overlook unless someone is paying close attention. A cross culvert that appears nearly full on a dry day, with no recent rainfall to explain elevated water levels, is one of those warning signs…

Across towns and counties, road departments replace cross culverts every day. The motivation is usually sound. Aging pipes fail without warning, and a collapse beneath the roadway can create a serious safety hazard, not to mention an expensive emergency repair. Proactive replacement is responsible a…

Street sweeping rarely gets much attention. It is slow, repetitive work, often done in the early morning hours, and the equipment itself can be temperamental and expensive to maintain. Sweepers are subject to constant wear, from abrasive debris, dust, and the mechanical strain of brushes, conveyors,…

As communities look for sustainable ways to manage stormwater, bioswales have become one of the most effective and visually appealing tools in the green infrastructure toolbox. They blend natural processes with engineered design to slow, filter, and infiltrate stormwater before it reaches local wate…

Infiltration-based best management practices, or BMPs, are designed to capture, store, and gradually infiltrate stormwater into the ground. These systems, which include bioretention basins, infiltration trenches, dry wells, and porous pavement systems, are particularly vulnerable during and immediat…
