Installing a Stormwater BMP is an important step towards protecting our waterways, but for them to perform as designed, they must be maintained regularly. Where do we dispose of the material removed from catch basins and stormwater treatment systems after maintenance?  I get that question regularly from both private and municipal maintenance

At the heart of every bioretention system is the media that captures and immobilizes pollutants that are then decomposed, volatilized and incorporated into the biomass of the system’s micro/macro fauna and flora. Bioretention media cannot be the heart of the system removing the intended pollutant load when flow rate is compromised due to premature

Let’s start by stating what I would consider to be an obvious fact: all Stormwater BMPs require maintenance. Whether we are talking about public domain or manufactured treatment devices, they all need routine maintenance to ensure they operate efficiently over extended periods of time.Maintenance is defined as the routine recurring work required to

I would consider myself a big picture thinker, always seeking to understand the full story, including the whys and how’s of a given situation.  I also like to probe below the surface and get my head around the root of a problem since that’s where the lasting solutions are usually found.  When I look around the full breadth of the stormwater

Three Components of Infiltration System DesignCommon infiltration practices include drywells, bioretention, permeable pavement, infiltration trenches, infiltration basins, and subsurface infiltration galleries. Regardless of their form, all infiltration systems have three primary components: storage, treatment, and infiltration.1. StorageRetention

An appropriately designed and manufactured high performance biofiltration system combines the benefits of natural biofiltration with the reliable and predictable performance of an engineered system. Each high performance biofiltration system utilizes a multifaceted approach including physical, chemical and biological processes to capture,

It’s that time of year again - temperatures have dropped below freezing, and the wintery weather has blown in. Departments of Transportation, state, local and city road crews are being kept on their toes, applying roadway treatments and safe passage for all of us. It is estimated that the US spends approximately $2.3 billion annually to keep highways free of snow and ice, and roughly 20% of transportation department budgets goes toward winter road maintenance.

As the New Jersey Department of Environmental Protection’s (NJDEP) certification program for Manufactured Treatment Devices (MTDs) has evolved over the years, one thing has remained consistent.  Confusion among stormwater professionals regarding the role that NJDEP plays vs. the role that the New Jersey Corporation for Advanced Technology (NJCAT)

Enjoying a spectacular fall in Portland, Oregon leads me to talk about street trees and leaves.As we all know the value of trees extends well beyond stormwater management.  Urban trees provide numerous benefits including providing wildlife food and habitat,  reduction of the heat island effect (up to 4 degrees C)  and reduction in CO2 emissions and

We’ve all heard the expression “can’t see the forest for the trees,” but when’s the last time you can remember it applying to yourself?  As a stormwater engineer, I’ve spent 15 years focusing on the design of natural systems and manufactured devices that treat and/or infiltrate post-construction runoff, and there is ample opportunity to get lost in
