Not Your Typical Rain Garden: The Journey of a Rain Drop at the James River Ecology School

by Amber Ellis, JRA's Watershed Restoration Associate/Volunteer Coordinator

Many of us have heard of rain gardens and know how great they are at reducing the amount of runoff leaving our homes and businesses and what a great tool they are in cleaning that runoff water. But have you heard of a garden that not only soaks up rainwater, but also grey water? Here’s a tour through a unique garden that was designed by JRA’s Landscape Architect, Amber Ellis to take care of the grey water produced from the bunkhouse (a tricky task on an island!), handle the overflow from the rainwater cistern, and provide a great educational landscape for the students.


 Rainwater flows through both downspouts on either side of the bunkhouse into the cistern underground. You can see the green top of the cistern if you look closely!


The grey water is sent to an underground tank that is a matrix of plastic cubes that resemble milk cartons. These are then wrapped in a fabric that allows the water to seep out, but keeps the dirt and debris out of the tank.

Once the tank is underground and the hole is filled with a bioretention soil mix (compost, sand, and topsoil), JRA’s volunteers came out on a cold day in March to install the plants and place the stones.



The plants used in the garden had to meet a lot of requirements including able to handle being really wet, really dry, deer resistant, and native.


 As of this August, the plants are doing great! The Goldenrod and Asters are already blooming!



 The only challenge will be keeping weeds out of the garden. Many of the students that come out to the Ecology School participate in service projects and maintaining this garden will be just one of the many projects they get to work on.
