courtyard, a bluestone patio with movable seating, integrated boulders and plantings, an artificial turf outdoor classroom area, a rain garden with footbridge, and lush plantings throughout the garden and terraces. The space offers several options for shaded and sunny seating so that students, staff, and faculty can enjoy the courtyard year-round. One of the challenges of the project is that it is an enclosed courtyard with only one access through the surrounding building. Special consideration had to be placed on constructability with the access restrictions. Smaller trees were specified, and the bridge over the rain garden and the benches were designed to be brought in piece-by-piece and built on site. The contractor brought in special equipment and machinery to build the steel canopy and move other heavy elements. Additionally, because it is an enclosed space, integrated stormwater management strategies were required to address the courtyard drainage issues, including the use of permeable paving and rain gardens. Both systems overflow to a conventional stormwater system, but manage and infiltrate much of the stormwater on site. The design of the rain garden celebrates the importance of stormwater management and transforms a functional element into a beautiful and educational feature. Water from the steel canopy structure drains to a stone strip and makes its way into the rain garden. The wooden pedestrian bridge that crosses the garden allows people to pass through and appreciate it up close. The lush plantings include eastern red cedars and October glory maples to create shade when grown, and Blue Ice Star flower, purple coneflower, hellebore and more for color and textural interest through all seasons. The garden creates a buffer between the main circulation paths of the courtyard and the bluestone patio to enhance the quiet and tranquil nature of the seating area. The rain garden, as well as the majority of the planting in the courtyard, is comprised of mostly native species to add habitat and ecological value. The courtyard at the DTCC Stanton campus was required to have a holistic design approach to create a successful renovation. The design integrates solutions that provide a space for students, staff, and faculty to enjoy, enhances the sustainability and environmental quality of the courtyard, and provides an aesthetically pleasing destination on campus to benefit the college for years to come. 48 Landscape Architect and Specifier News Purple Coneflower (Echinacea purpurea) Calico Aster (Symphyotrichum lateriflorum) Common Milkweed (Asclepias syriaca) Eastern Red Cedar (Juniperus Virginiana) Mountain Laurel (Kalmia Latifolia) Obedient Plant (Physostegia Virginiana) Top: The rain garden, planted with red cardinal flowers amongst other native plants, is separated from the rest of the courtyard by an ipe bridge. Drainage was a major consideration; rainwater falls from the steel canopy to a bed of stones from which it filters into the garden. Any stormwater that does not infiltrate the rain garden overflows to a conventional stormwater system. Below: While the rain garden is paved with irregular bluestone pavers, much of the rest of the courtyard has permeable paving. The blue bench in the foreground was custom made by Victor Stanley. The 'Anthro Sites' series wooden table is accented with coordinating colors.
