At first glance, it's easy to get excited over how much innovation has occurred in the field of stormwater management in recent years.  A wide variety of new stormwater control measures (SCMs) have been developed and deployed for use while we simultaneously worked to refine our design standards for our tried and true practices to improve their functionality. 

Stormwater quality regulations continue to expand to include treatment criteria for total phosphorus. Phosphorus is now the second-most-regulated pollutant in stormwater runoff after total suspended solids. While much has been written about BMPs used to remove total phosphorus, we shouldn’t underestimate the role BMP maintenance has on reducing phosphorus levels. More specifically, we should take into account the timing of maintenance events and the type of maintenance being performed.

High-flow bioretention systems target the removal of suspended solids, total and dissolved nutrients and metals, oil and grease, trash, and debris. Components

Oil changes. Gutter cleaning. Annual doctor appointments. These are all forms of maintenance that most people would likely agree are necessary to keep our

Many manufactured stormwater filtration systems use media-filled cartridges. During a storm, runoff passes through the filtration media, which absorbs and
