Raingardens
Rain Gardens are growing in popularity as a contemporary and ecologically responsible focal point of today's urban landscape. The majority of Rain Gardens that we install are applied as a solution to site drainage issues as well as for intercepting and filtering runoff in a collaborative storm water path of travel from multiple properties.
Rain Gardens intercept and capture storm-water runoff which then is both taken up by plant material and infiltrated through the garden. Contaminants found in runoff are filtered by plant material and soil structures in the garden. Rain Gardens are planted in a slight depression or swale 12-24" maximum below finished grade of the existing landscape. Native Plants are commonly used because they have deep roots often averaging 4-6' in depth. These deep roots penetrate the earths soils creating cavities for water to infiltrate. So in essence Rain Gardens actually become more efficient over time. Elevations of each installation is important as there is an inlet and outlet. The inlet is higher than the outlet so in large, less common storm-water events, water does not back up. The garden will fill up and overflow via the outlet and continues its path of travel problem free.

Why We Are the Best Installer and Guarantee It
Rain Gardens can be a high maintenance problematic burden on your property when important design elements are ignored which we find quite common from our municipal and commercial customers. Our primary business is Sustainable Landscape Design, Drainage Solutions, and Ecological Services all of which mend together perfectly when it comes to engineering Rain Gardens that perform in even the toughest of sites.
​
When designing Rain Gardens we utilize plant materials that are suitable and manageable for residential and commercial landscape applications. rain garden maintenance can be an intensive process when incorporating an overly diverse community of Native Plants and often become problematic on the tail end when it comes to managing the garden. With this in mind we look at each project from a landscape design perspective and while the majority of plants we use are Native Plants of Minnesota, we choose non-invasive species and sometimes incorporate non-native varieties to achieve specific goals in tough sites such as full shade Rain Gardens.
​
The industry standard performance for a Rain Garden is to capture and infiltrate a 1" rain event within 24 HRs. We often oversize and optimize our gardens to exceed the average expected performance so we can be absolutely sure we accomplish our goals for each site. All of our Rain Gardens and Drainage products are backed by a 2 Year Performance Guarantee.
Runoff -The Journey
Storm water runs off impervious surfaces and picks up residuals including fertilizer and pesticides, animal waste, litter, oil, and eroded sediment.
Algae feeds on dissolved oxygen and deposited minerals, depleting the body of water's organisms of oxygen needed to survive. In addition, some algae produces toxins which are harmful to fish, wildlife, pets and humans.
Water and its accumulated residuals, move by gravity from higher elevations to lower catchments picking up additional pollutants.
Pollutants are deposited into natural lakes, streams,and rivers which contaminate the body of water and mix with sunlight to promote vigorous algae growth.
