Rain Gardens

The Gunpowder Valley Conservancy has designed conservation gardens since 2009 as part of watershed restoration projects.

Conservation gardens include rain gardens, Bayscape gardens, edible Bayscape gardens, and microbioretention practices. These gardens are attractive, practical, and can be sized to fit any yard or landscape. Designed to mimic nature, these gardens are comprised of hardy native plants that naturally provide food and habitat for species native to the Gunpowder watershed.

What is a Rain Garden?

A rain garden is a beautiful and functional solution to storm water runoff. Water-loving native flowers, grasses, shrubs, and/or trees are planted in a low spot on a property to absorb and filter rainwater.  A typical rain garden is designed to capture water from a 1" rain storm and drain within 24-28 hours of a rain event.

Storm water runoff is the water that flows over hard (impervious) surfaces, including roads, rooftops and driveways, to the storm drains or directly to a water body.  This excess water can easily become polluted by automotive oils, garbage, sediment, and lawn chemicals as it flows through developed areas. Flooding has become a common problem in our communities due to the loss of natural areas that allow rain water to soak back into the ground.

Rain gardens are a great solution! When you plant a rain garden on your property you are:

  • Promoting clean water by filtering storm water runoff before it reaches local waterways
  • Improving water drainage issues
  • Creating an attractive landscape that enhances the community
  • Supporting native plants and wildlife, including pollinators
  • Reducing yard maintenance

Native plants are adapted to Maryland's climate, so they can handle our seasonal droughts with little watering and don't need as much fertilizer to grow in local soils.  Less fertilizer means less nutrient pollution in the Chesapeake Bay.
