Where Stormwater Strategy Meets Practical Guidance

The Fundamentals of Field Inspections for Catch Basins, Culverts, and Outfalls.

Field inspections of catch basins, manholes, culverts, and outfalls form the foundation of responsible stormwater management. These routine checks give municipalities an ongoing view of the condition of their drainage network and allow crews to identify issues long before they become flooding hazard…

Recognizing Early Signs of Habitat Disruption Around Drainage Structures

Habitat disruption around drainage structures is often subtle at first, and many of the earliest signs tend to appear during ordinary field work rather than during formal environmental surveys. Because highway departments and public works crews encounter these locations regularly, they are in the be…

How Harmful Algal Blooms Form, and Why Road Salt Is Making the Problem Worse

Harmful algal blooms have become one of the most pressing water quality problems in many regions, and their rise has been linked to a complicated blend of ecological, climatic, and human factors. In freshwater systems, these blooms are most often caused by cyanobacteria, commonly known as blue green…

The Life and Death of the Salton Sea

The Salton Sea is one of California’s most unusual and tragic landscapes, a place shaped by accident, transformed by ambition, and ultimately pushed toward collapse by the very forces that sustained it for decades. Its story is a long arc of creation, prosperity, decline, and ongoing struggle,…

Key Elements of Green Infrastructure: An In-Depth Overview

Green infrastructure has become one of the most effective approaches for managing stormwater while improving the health and resilience of our communities. Rather than relying solely on traditional "gray" infrastructure such as pipes, culverts, and concrete channels to move stormwater downs…

Tracking Salt Use with a Telematics Dashboard

How data-driven winter operations cut chloride, costs and compliance risk Why tracking matters Road salt protects drivers, yet the same chloride that melts ice can accumulate in lakes, drinking-water wells and public infrastructure. The Adirondack Road Salt Reduction Task Force warns that “mig…

Five Red Flags in Culvert Inspections (and the Tools to Spot Them Fast)

Culverts are among the most overlooked pieces of municipal infrastructure, yet they play a critical role in keeping roads passable and communities safe from flooding. When a culvert fails, the results can be immediate and costly: road washouts, property damage, and emergency closures. That is why re…

The Role of the Clean Water Act in MS4 Regulation

The Clean Water Act is the foundation of modern water pollution control in the United States. While many people associate the law with industrial pollution or wastewater treatment plants, it also serves as the legal basis for regulating stormwater runoff through Municipal Separate Storm Sewer System…

Decoding FEMA’s BRIC Program for Small MS4s

For almost five years the Building Resilient Infrastructure and Communities (BRIC) grant program served as FEMA’s flagship source of hazard-mitigation funding. It directed a steady slice of federal disaster-relief dollars toward projects that would lower future losses, and many small Municipal…

Slip-Lining Culvert Pipes

When a culvert begins to corrode, crack, or separate at the joints, engineers and highway departments often face a choice between excavating the old pipe and installing a new one or rehabilitating the existing structure in place. Slip-lining is the most widely used trenchless rehabilitation techniqu…

Culvert Fundamentals: A Practical Overview for Municipal Stormwater Systems

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…
