Is a Catch Basin Appropriate Here? Before a catch basin is installed, it is important to step back and ask a simple but often overlooked question, what purpose is it actually going to serve at this location? Catch basins are frequently installed out of habit or because “there has always been o…

Culverts are often out of sight and, as a result, out of mind, until they fail. When they do fail, the consequences can range from nuisance flooding to full roadway washouts. One of the most overlooked factors in culvert performance is vegetation management. Too little control can obstruct flow and …

Municipal road crews are on the front lines of stormwater management whether they realize it or not. Every ditch they shape, every culvert they install, and every roadside repair they complete has a direct impact on how water moves across the landscape. Yet in many public works departments, stormwat…

Retention and detention ponds are among the most recognizable features of modern stormwater management systems, yet they are often misunderstood or used interchangeably. While both are designed to manage runoff and protect downstream infrastructure, they serve distinct purposes and function in very …

Housing density is often discussed in terms of zoning, neighborhood character, or affordability, but it has a direct and measurable impact on stormwater runoff. In Using Smart Growth Techniques as Stormwater Best Management Practices, the U.S. Environmental Protection Agency makes a compelling case …

Municipal leaders and highway departments are under constant pressure to maintain aging infrastructure with limited local budgets. Culverts fail, roads deteriorate, and drainage systems quietly reach the end of their useful life, often without the funding needed to address them. Yet, while many muni…

Building a stormwater asset inventory often begins in a very familiar place, a spreadsheet opened by someone who knows the system well enough to start writing things down. There is nothing wrong with that starting point. In fact, many successful asset management programs begin with a simple table of…

Stormwater asset management is one of those concepts that sounds technical and abstract, yet at its core it is simply about knowing what you own, understanding its condition, and making informed decisions before problems turn into emergencies. For municipalities responsible for miles of pipe, hundre…

Stormwater outfalls are the final point where a drainage system releases water into a receiving body such as a stream, river, wetland, or lake. Because they sit at the end of the system, they are often overlooked until a visible failure occurs. When an outfall collapses or erodes, the consequences c…

High density polyethylene, commonly referred to as HDPE, has become a widely used material for culvert pipe applications because it is lightweight, corrosion resistant, and relatively easy to install. In roadway and stormwater infrastructure, HDPE culverts are frequently selected as an alternative t…

Open channel outfalls occupy a unique space in stormwater infrastructure. They are simple in appearance, often nothing more than a vegetated swale or gently graded channel, yet when properly designed they function as treatment systems, flow control measures, and in northern climates even snow manage…

Dry weather outfall screening is one of the most effective and defensible tools available to municipal stormwater programs for identifying illicit discharges. Under MS4 permit requirements associated with the Clean Water Act and the NPDES stormwater program, municipalities are required to implement …
