Rain gardens provide an attractive solution to water ponding and yard drainage issues. In urban and suburban settings, rooftops, roadways, and other paved surfaces cause water to move quickly across their surfaces. This increased rate of flow reduces the ability for water to soak into the ground and reach the groundwater system. Using these shallow depressions planted with native plants reduces the amount of water on the surface of your lawn and slowly filters water as it moves into the ground. Rain gardens are also pretty and inviting to wildlife such as butterflies and birds and are nearly maintenance free once established.
Native plants filter rain water removing sediment and nutrient pollutants from runoff. Every time it rains, water gushes from your downspouts across your lawn into local streets picking up pesticides, sediment, and nutrients before flowing into local storm drains. Depending on the slope of your lawn, rain may cause ponding or wetspots within your yard. Once in the storm drain system, polluted runoff is carried directly to the Blue River. Installation of a rain garden can reduce the flow of polluted runoff from of your property during the first flush of rain allowing water to slowly move into the groundwater system. The more water you retain on site, the less water flows across the land surface resulting in less sediment and nutrient polluted runoff flowing directly into the Blue River.
