• Bioretention Cells (or Bioswales). Bioretention cells are depressions containing vegetation grown in an engineered soil mixture placed above a gravel drainage bed that provide storage, infiltration, and evaporation of both direct rainfall and runoff captured from surrounding areas.
• Continuous Permeable Pavement Systems. Permeable pavement allows rainfall to immediately pass through the pavement into the gravel storage layer below where it can infiltrate at natural rates into the site’s native soil. In block paver systems, rainfall is captured in the open spaces between the blocks and conveyed to the storage zone and native soil below.
• Green Roofs. Green roofs are a variation of a bioretention cells that have a soil layer atop a special drainage mat material that conveys excess percolated rainfall off of the roof. They contain vegetation that enable rainfall infiltration and evapotranspiration of stored water.
• Infiltration Trenches. Infiltration trenches are narrow ditches filled with gravel that intercept runoff from upslope impervious areas. They provide storage volume and additional time for captured runoff to infiltrate the native soil below.
• Rain Barrels or Cisterns (Rainwater Harvesting). Rain barrels and cisterns are containers that collect roof runoff during storm events and can either release or re-use the rainwater during dry periods. Cisterns may be located above or below ground and have a greater storage capacity than a rain barrel.
• Rain Gardens. Rain gardens are depressed areas, planted with grasses, flowers, and other plants, that collect rain water from a roof, driveway, or street and allow it to infiltrate into the ground. More complex rain gardens are often referred to as bioretention cells.
• Rooftop (Downspout) Disconnection. This practice allows rooftop rainwater to discharge to pervious landscaped areas and lawns instead of directly into storm drains. It can be used to store stormwater (e.g., in a rain barrel) and/or allow stormwater to infiltrate into the soil (e.g., into a rain garden or lawn).
• Vegetative Swales. Vegetative swales are channels or depressed areas with sloping sides covered with grass and other vegetation that slow down the conveyance of collected runoff and allow it more time to infiltrate the native soil beneath it.
