48 Landscape Architect and Specifier News new construction on the existing city drainage system downstream of the site. The large, heavily planted bioswale and adjacent lawns create a dense buffer for the single-family residential neighborhood to the south. With the largest feature on the south end of the site, the ability for patrons to experience this was limited. The primary entrance to the building is located on the northeast corner of the site. Adhering to the same design parameters, the design team created a miniature version of the bioretention cell system as a nod to the importance of the primary stormwater treatment area, even providing opportunities for patrons and passersby to crossover the bioretention cells on boardwalks and experience a small piece of nature within an urban environment. This space now met several site needs, including safe passage into the building, stormwater management and human scale. The use of locally sourced materials for site features, including the Mount Airy Granite (quarried near Greensboro), Pine Hall clay pavers (fabricated just north of Greensboro) and regionally grown plant materials helped keep the carbon footprint of these materials low, while supporting the local economies and trades. The site improvements for the Leonard J. Kaplan Center for Wellness at the University of North Carolina at Greensboro are not only beautiful but "hard working." A variety of hardscape materials and vegetation are arranged in a repetitive banding pattern that erodes as one travels to the east on the site into a pick-up-sticks pattern. This design is clearly visible from the glass-enclosed cardio area, which is cantilevered over the facility's front doors. In front of the facility is a demonstration rain garden that slows and filters rainwater and runoff before it enters the storm system and ultimately the local watershed. The brushed concrete intersects with the paver bands and Brazilian hardwood boardwalks, which traverse a mulch bed of trees, flowering plants and switchgrass, all selected for their ability to tolerate periods of saturation and drought. Two hardscape bands are extended by dotted lines of Kaplan Center Continued from page 46 Asclepias tuberosa (mildweed) Amsonia tabernaemontana (Bluestar) Chinacea purpurea (coneflower) Hemerocallis ('Happy Returns' daylily) Liatris spicata (Liatris) Lobelia cardinalis (Cardinal flower) Under the EPA's National Pollutant Discharge Elimination System (NPDES) ( https://tinyurl.com/yajs3s3c ) Greensboro is required to reduce adverse impacts to water quality and aquatic habitat by "instituting controls on stormwater that have the greatest likelihood of causing continued environmental degradation." Here, the "controls" are bioretention cells, essentially bioswales with weir walls to collect stormwater. The site design achieved LEED® Gold certification. PHOTO: JIM SINK Continued on page 88
