Whether you live in the city or along a lake or river, managing stormwater runoff is important.
Rooftops, roads, driveways and sidewalks are hard surfaces that prevent rainwater and melting snow from reaching the soil and soaking into the ground. These hard surfaces also collect nutrient-rich yard and pet waste, oil and radiator fluid from autos, and other debris and pollutants. Rain gardens can capture this runoff and filter it before it gets into streams, lakes, and rivers!
