Rain gardens are common in many communities, both in public and private spaces. They’re the installations of native shrubs, perennials, and other vegetation planted within depressions in the landscape, usually along a natural slope. A rain garden is designed to allow a large portion of stormwater runoff to soak into the ground rather than rush by, which can cause erosion and other issues downstream.
As the most universally accessible form of Green Stormwater Infrastructure (GSI), a rain garden can be easily added to nearly any landscape. Adding this technology creates additional pervious surface — especially in urban communities — and is engineered to manage very specific volumes of water. The result: decreased velocity of flow, less flooding, and fewer pollutants getting to municipal infrastructure and your local waterways (streams, rivers, lakes, and oceans).
Rain gardens are the most accessible and affordable form of green stormwater infrastructure. They can be added to any residential project, creating a whole world of opportunity. We’re proud to give this solution our ‘Green Ribbon’ designation.
Rain gardens provide some of the most accessible ways to manage stormwater. As part of the stormwater treatment train, a rain garden can be installed to dramatically slow the rate and volume of stormwater runoff.
With a reduction in stormwater runoff volume and velocity of flow, there’s less chance of backed up stormwater and combined sewage overflow systems (CSOs) [link to CSO definition on FAQ page]. This means drains can operate the way they’re supposed to, avoiding costly floods.
