1. Disconnection of Rooftop Runoff

   Rooftop disconnection involves directing flow from downspouts onto vegetated areas where it can soak into or filter over the ground.

2. Drywells

   A drywell is an excavated pit or structural chamber filled with gravel or stone that provides temporary storage of stormwater runoff from rooftops.

3. Permeable Pavement

   Permeable pavers are alternatives that may be used to reduce imperviousness. While there are many different materials commercially available, permeable pavement may be divided into three basic types: porous bituminous asphalt, pervious concrete, and permeable interlocking concrete pavements.

4. Rain Barrels

   A rain barrel is a container that captures and stores rainwater draining from your roof. Barrels usually range from 50 to 80 gallons and have a spigot for filling watering cans and a connection for a soaker hose.

5. Rain Gardens

   Rain gardens are an environmentally friendly way to beautify your lawn's landscape while protecting water quality.

6. Swales

   Swales are channels that provide conveyance, water quality treatment, and flow attenuation of stormwater runoff. Swales provide pollutant removal through vegetative filtering, sedimentation, biological uptake, and infiltration into the underlying soil media.
