Protection Activity: Best Management Practices

Low impact development is an approach to land development (or redevelopment) that incorporates natural features to manage stormwater and protect water quality. Low impact development minimizes runoff by promoting infiltration, evapotranspiration, and collection for use through natural landscape features and fewer impervious surfaces. The result is a functional and visually appealing development that treats stormwater as a resource, not as waste. 

A rain barrel is any type of container that collects rainwater from downspouts and rooftops. As water accumulates in the container, it can be used for activities such as watering gardens or washing cars.By collecting and storing rainwater, rain barrels reduce flows to nearby receiving waters, especially during storm events.
