The rain garden planting at the Horticulture building diverts roof runoff from the combined sewer and transfers it to the ground in front of the building. The paver entrance walk exposes the water coming down from the downstops for people to be able to see it for themselves. Student inputs were also sought from two different classes on planting and layout construction design, so that the rain garden partly reflects their work. Faculty inputs were also solicited for the design. Office of University Sustainability
