A Look at the English Brook Delta in Lake George, New York Sediment is a natural part of any water system, but when it accumulates faster than a system can handle, it begins to change the waterbody in ways that are both visible and subtle. Excess sediment alters water clarity, transports nutrients, …

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…

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…

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…

A complete and accurate stormwater map is one of the most important responsibilities for any community that operates as a Municipal Separate Storm Sewer System, or MS4. These maps are not created merely to satisfy a regulatory checkbox. They protect waterways, support field crews, reduce liability, …

Culverts are enclosed conduits that carry surface water beneath roads, railways, trails, and embankments, allowing drainage and traffic to coexist safely. They form one of the most common, and often most overlooked, structures in municipal stormwater networks. When sized, installed, and maintained c…

Municipal Separate Storm Sewer System (MS4) permits rest on a simple idea: you cannot manage what you have not first documented. The Environmental Protection Agency (EPA) defines an MS4 as any publicly owned system of drains, pipes, ditches, or similar conveyances that carries runoff to waters of th…

Natural streams, creeks, and drainage swales evolved to carry rainfall runoff long before culverts and pipes existed, and they remain one of the most efficient, resilient, and cost-effective elements in any municipal stormwater network. When a community plans for development or retrofit, treating th…

Stormwater management succeeds when the landscape itself is considered the first line of defense. Certain parts of that landscape offer outsized benefits or face outsized risks, and thoughtful planning around them is essential. Special Value Features are areas that deliver exceptional stormwater ben…

A brownfield is real property whose reuse or redevelopment is complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. Congress added this definition to the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), recognizing that l…
