Low Impact Development: Downspout Disconnection

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. 

Downspout disconnection - Rooftop runoff can flow indirectly or directly to storm sewers or surface water, taking pollutants with it. Pollution and increased flow can harm fish, wildlife, habitat, and drinking water. If flooding occurs, sewage and wastewater can also flow into natural waterways. To reduce water quality impacts, redirect flow from downspouts into yards or gardens to reduce the amount of runoff by allowing some infiltration and remove some pollutants through the soil and vegetation.
