Rain Gardens in Washtenaw County

Learn how to design your own rain garden by taking our Master Rain Gardener Certification class. Or plant a rain garden on your property with technical advice from the Washtenaw County Rain Garden staff. As a rain gardener, or Master Rain Gardener, you can become your neighborhood's expert and spread the word about the benefits of rain gardens.

Jessen Rain Garden spring 2012What are Rain Gardens?

Rain gardens capture stormwater runoff before it pollutes our local rivers - while providing beautiful gardenscapes throughout the growing season.

Mother earth creates the rain - but we create the runoff.  When rain hits the roofs, streets and driveways of our neighborhoods, it washes pollution into the river. A rain garden captures the rain water runoff and filters it clean. One inch of rainfall means 600 gallons of water will be captured by a typical rain garden.  This is water that won't go to municipal pipes, won't add pollution to the river, and won't contribute to flooding. This water will recharge the groundwater.  But before it does, it keeps the garden looking green and lush.

Rain Garden Design Assistance for Homeowners

 harry and francineThe Office of the Washtenaw County Water Resources Commissioner and staff work with several homeowners each year to design and install rain gardens on their property.  Our office offers a personalized visit and design advice - the homeowner builds the rain garden. The result is residents all over the county are happy with their new gardens, and the Huron River receives less fertilizers, chemicals and other harmful runoff.  For a site visit to your property in Washtenaw County, contact our Rain Gardens Coordinator, Susan Bryan at bryans@ewashtenaw.org.

The rain gardens planted through this program are capable of capturing 60,000 gallons of water - an inch of rainfall.

Wet Basements

Some homeowners that seek rain garden help are experiencing wet or flooded basements and are looking for a way to reduce the amount of water that ends up inside their home. If you have rain water flowing towards your house, we can provide technical assistance to determine if a rain garden can help alleviate your problem. More information on the causes and solutions to wet basements can be found through Kingston Utility.

You may be able to solve the problem simply by clearing debris off the nearest catch basin, or storm drain. Make sure your downspouts are clear and any cracks in your foundation are repaired. If simple solutions do not solve your wet basement problem, then consider the grade of your yard. If your grade is sloping towards your house, then the area may need to be re-sloped because water will always follow gravity! A rain garden could alleviate your wet basement problems depending on the groundwater table and your property characteristics. Contact Susan Bryan, bryans@ewashtenaw.org for more information.
