Download SVT's rain garden brochure, with tips on landscaping to improve water quality.
A rain garden is a natural or dug shallow depression which captures and soaks up stormwater from roofs, sidewalks, and driveways.
As more and more impervious surfaces are created through development, stormwater runoff becomes a problem. By the time it reaches storm drains, stormwater tends to have accumulated pollutants such as oil, salt, and fertilizers. That water then runs into our rivers and reservoirs, negatively impacting water quality. Impervious surfaces also increase the speed of stormwater, which causes erosion and sediment accumulation in water bodies.
Rain gardens slow runoff and filter pollutants before they enter our waterways. They allow more water to recharge underground aquifers, and also add beauty to the landscape, help prevent erosion, and may provide food for wildlife. Rain gardens may also replace areas of lawn, and, once established, can be very low-maintenance.
Wolbach Farm's rain garden was planted with the help of a local Brownie Troop, and is located on the south side of the house, outside of the kitchen.
