Project Description:
Our company was contracted to do a master plan for the family who was in desperate need of a rear yard renovation. The existing lawn area remained saturated throughout most of the year and the runoff from the neighboring property ran across their back yard, down the side of their property and all the way to the sidewalk in front of their house. The water was so intense that it had begun to cut through the back yard and erode the soil across the sidewalk and into the nearby storm drain.

By identifying these drainage problems and discussing solutions with the homeowner, we were able to design and create the aesthetically pleasing and sustainable solution of a rain garden. The goal was to slow down storm water runoff, and catch pollution and sediment by creating a rain garden that acts as a filter prior to entering the storm drain, while enhancing the aesthetics of the property.

The rain garden created was a shallow depression, 12 - 16" deep that collects rainfall runoff from all downspouts of the home and water collected into perforated pipes underneath the lawn area. The perforated pipe begins at the highest elevation in the yard and ends in the rain garden, the new lowest elevation that has been excavated down to an 8" depth. The perforated pipe captures the runoff water and allows the water to seep slowly back into the
ground as it runs across the property and into the garden. The garden was lined with a geotextile filter fabric to aide in removing contaminants from the water, prevent migration of the stone in to the soil, and minimalize maintenance.

A large variety of plant material was chosen, focusing mainly on native wetland species for their tolerance of our local soil types, moisture conditions and
the habitat they provide for wildlife. The garden was abundant with native wildlife and was a sustainable ecosystem for birds and butterflies upon completion of the project.

After planting, we arranged decorative stone throughout the garden to slow the flow of water and help prevent erosion. The combination of vegetative and stone surfaces provides temporary storage for runoff before the water either evaporates or infiltrates the soil.

The surrounding beds throughout the property were also all amended with compost and replanted with plants that work in harmony with the rain garden. The front, side, and rear yards are a beautiful display of colors that bloom throughout the seasons and the plants throughout the entire property provide food and shelter for native wildlife.

The rear yard that was once a muddy play space for the kids is now a dry lawn space that can be utilized by the family and their neighbors. This multi­ functional garden has become the focal point of the residence.
