The Hidden Costs of Undersized Culverts: How Small Openings Create Big Watershed Problems

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…

From Pipes to Plants: How Cities Transition Stormwater Budgets to Nature-Based Solutions

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…

Key Design Elements of a Rain Garden and Why They Matter

Rain gardens are among the most recognizable and effective forms of green infrastructure. Although they often resemble attractive landscaped planting beds, a properly designed rain garden is a carefully engineered stormwater management system. Every component, from the shape of the basin to the soil…

How Green Infrastructure Supports Biodiversity in Urban Stormwater Systems

Stormwater management has traditionally focused on one primary goal, moving runoff away from roads, buildings, and neighborhoods as quickly as possible. While this approach successfully reduces flooding, it often leaves behind landscapes dominated by pavement, pipes, and manicured turf that provide …

Common Points of Failure in Rural Stormwater Drainage Systems

Stormwater drainage systems are among the most critical yet overlooked components of rural infrastructure. Hidden beneath roads, driveways, fields, and stream crossings, culverts and drainage pipes quietly transport runoff away from roadways and developed areas. Many rural drainage systems were inst…

Thermal Pollution and Stormwater Runoff: Impacts and Mitigation Strategies

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…

The Value of Vigilance: How Road Crews Prevent Culvert Failures Before They Happen

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…

How Stormwater Runoff Causes Fish Kills: Mechanisms, Pollutants, and Environmental Impacts

Stormwater runoff can cause fish kills through a combination of physical, chemical, and biological mechanisms that alter aquatic environments beyond the tolerance limits of fish and other aquatic organisms. These impacts are often rapid, episodic, and closely tied to precipitation events, especially…

Why Some Roads Have “Wings”: Rethinking How We Move Stormwater

*Author's note: The primary image paired with this article depicts a road with a paved wing - Richmond Hill Drive in Queensbury, NY, to be precise - while flooded during a pre-thaw heavy rain event. A winged road with adequate drainage would not normally retain that amount of stormwater. If you …

What Is a Bioswale and How Does It Work?

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…

Choosing Between a Catch Basin and Pipe System or a Dry Well: Making the Right Call for Stormwater Drainage

When addressing a drainage problem, one of the most important decisions is whether to move water away through a traditional catch basin and pipe system or to manage it on-site using a dry well. Both approaches are widely used and effective when applied in the right context, but selecting the wrong s…

Installing a Catch Basin: A Step-by-Step Guide

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…
