Eligible best management practices (BMPs)

Best management practices (BMPs) are methods used to treat stormwater runoff.

Bioretention/raingarden

A soil and plant–based stormwater management BMP used to filter runoff. Bioretention facilities are typically shallow depressions located in upland areas. Runoff that flows into the basin drains through the soil which filters pollutants.

Permeable pavement

These are paving surfaces that allow stormwater runoff to filter through surface spaces into an underlying stone reservoir. They are suitable for driveways, trails, parking lots, and roadways with lighter traffic. The most commonly used permeable pavement surfaces are pervious concrete, porous asphalt, and interlocking concrete pavers. All permeable pavements have a similar design layering system: a surface pavement layer, an underlying stone aggregate reservoir layer, and geotextile over non-compacted soil subgrade. Runoff is filtered through the surrounding naturally permeable soil.
