Soak It Up!
Infiltration practices are natural or constructed areas that slow, filter and absorb stormwater. They also attract and provide habitat for butterflies and birds, and serve as attractive landscaping. Infiltration practices can include:
Rain Gardens
Shallow landscaped area that requires removing some portion of the existing soil and replacing it with a sandy soil mix that can hold and filter several inches of water. In addition, rain gardens are planted with specially selected native plants that can hold up in wet conditions.
Dry Wells
Small, excavated pits typically about 4-6’ deep, filled with stone or gravel that temporarily store stormwater runoff until it infiltrates into the surrounding soil. A downspout can connect directly to a dry well.
Green Roof
Green roofs are a way to transform a conventional flat roof – typically black – into a green “carpet” that effectively manages rainwater by retaining and filtering water through plants and soils. In addition to managing rainwater, green roofs provide an additional layer of insulation to a building thereby reducing heating and cooling costs, can double the life of a roof, improve air quality, reduce the urban heat island effect and can provide garden areas and attractive views.
A Stormwater Permit from the City is likely required for these actions, because changes you make could accidentally cause a negative impact other areas.
