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…

Stormwater culverts come in a wide range of materials, and each type carries a unique combination of strength, lifespan, cost, and installation considerations. Choosing the right material is not a one size fits all choice, because every site presents different soil conditions, hydraulic needs, envir…

Opening and entering drainage structures requires a practiced, methodical approach that protects workers from unseen dangers and ensures that every step is guided by awareness, communication, and control. These environments can hold toxic gases, low oxygen levels, and unexpected structural weaknesse…

Constructed wetlands are engineered systems that mimic the natural processes of a real wetland in order to treat stormwater, wastewater, or other polluted runoff. They are intentionally designed and built rather than formed through natural hydrology, but they function in much the same way. Water flo…

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…

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…

Riparian corridors, the vegetated strips that border rivers, streams, and lakes, serve as protective edges for both land and water. They filter pollutants, stabilize banks, slow floodwaters, recharge groundwater, and create habitat highways for fish and wildlife. When these corridors are degraded by…

Geocells, also known as cellular confinement systems, have become a trusted solution in the design and maintenance of modern drainage infrastructure. These innovative materials provide structural stability to soils and aggregates, making them particularly useful in applications where erosion control…

What exactly is an SWCD? Created under state law in every state and most U.S. territories, nearly 3,000 locally led Soil and Water Conservation Districts now cover almost every county in the nation. Their boards, typically a mix of farmers, municipal officials, and at-large residents, design and del…

Why We Need a New Approach Annual (or even quarterly) MS4 refresher courses are mandatory under the NPDES Phase II program, yet completion logs and pop-quiz scores often reveal that municipal crews quickly forget key practices such as spill-response or best management practice (BMP) housekeeping. En…

Every municipality owns drawers, or entire vaults, of ageing drainage “plan sets”: linen originals from the 1930s, blueprint mylars from the 1960s, contractor mark-ups from a 1998 sewer separation project, and everything in-between. Transforming those static sheets into a living GIS data…

Upgrading stormwater infrastructure is a pressing priority for municipalities across the country, yet it often comes with a hefty price tag. Whether addressing outdated culverts, installing green infrastructure, or improving data management and compliance under an MS4 permit, funding is frequently t…
