Stormwater BMPs

Bioretention

The actual installation of bioretention areas is much more sophisticated and complex than many bioretention advocates admit.

Green Roof

Green roofs are great at reducing runoff volume, but are not so great at reducing nutrient concentrations, however, is not a major drawback.

Infiltration

Infiltration has the highest runoff reduction capability of any stormwater practice, and probably comes closest to replicating predevelopment hydrology, but they require careful design and testing to work properly.

Non-Structural BMPs

Non-structural BMPs are institutional, educational or pollution prevention practices designed to limit the amount of stormwater runoff or pollutants that are generated in the landscape. Ideally both non-structural and structural BMPs should be employed in the landscape to treat stormwater runoff. The use of non-structural BMPs upstream can reduce the amount of runoff being generated...Learn more...

Permeable Pavers

Permeable pavements are alternative paving surfaces that allow stormwater runoff to filter through voids in the pavement surface into an underlying stone reservoir, where it is temporarily stored and/or infiltrated. A variety of permeable pavement surfaces are available, including pervious concrete, porous asphalt and permeable interlocking concrete pavers.

Ponds

The reputation of dry Extended Detention ponds is tarnished by their mediocre nutrient removal and minimal runoff reduction capability.

Rainwater Harvesting

Rainwater that falls on a rooftop is collected and conveyed into an above- or below-ground storage tank where it can be used for non-potable water uses and on-site stormwater disposal/infiltration.

Sand Filters

Sand filters can remove a wide range of pesky pollutants, such as metals, hydrocarbons, bacteria, and trash, and are nearly an essential at every stormwater hotspot.
