Achieves SITES Gold Certification by Adapted from the United States Botanic Garden Website
Just across Independence Avenue from the U.S. Botanic Garden Conservatory is a favorite "secret" garden of many Washingtonians, a refuge from the stresses of the city. Secluded benches offer quiet shade in the summer and sheltered sunlight in the winter. Every type of plant is represented in the Park - deciduous trees, evergreens, shrubs, perennials, annuals, vines, ground covers, roses and bulbs. In every season, the colors and textures of the plants and flowers are exhilarating. Created in 1932, Bartholdi Park, at the United States Botanic Garden (USBG), has served as a demonstration garden for more than 87 years and until 2016 had not undergone a complete renovation since its original construction. The much-needed renovation provided an opportunity to increase accessibility, showcase the Sustainable SITES Initiative (SITES) principles in action, and demonstrate USBG's commitment to sustainability. Now that the renovation of the park is complete, the new garden is a showcase of sustainable gardening, having achieved SITES Gold certification for its sustainability strategies and becoming the first project in Washington, D.C., to be certified under SITES version 2. (See SITES Sidebar, page below) Renovation plans focused on SITES's key areas: water, soil, plants, materials, and human health: Water: Ten rain gardens capture 100 percent of rainfall on the site and allow it to soak into the ground, diverting runoff from D.C.'s combined sewer system. The rain gardens can accept up to 4,000 cubic feet of water in a 24-hour storm event - equivalent to 256 bathtubs of water. The project also used permeable paving and reduced the amount of impervious surface. Plants: The gardens in Bartholdi Park showcase plants native to the Mid-Atlantic region and a collection of edible plants in permanent and seasonal plantings in a new kitchen garden. The project team was able to save multiple large trees and shrubs on site; other plants were reused on Capitol Hill and in D.C. Public Schools. Soil: During the renovation, topsoil was removed, saved off-site, amended with organic compost and returned to the park for the new plantings. In areas where plants were saved, the soil was also protected from compaction. Materials: Existing concrete sidewalks were crushed and then used as the base layer under the new sidewalks. Previous stone walls were disassembled and their stones were reused in the new walls for the raised kitchen garden. Flagstone from previous pathways was also salvaged to create new paths. For the park's locally sourced furniture, a Virginia company built seating and tables from white oaks that had fallen naturally during a storm. Human Health: The park connects people to nature through programming that includes yoga and nature-in-motion walks. Additional seating, a water fountain, and bicycle parking were added. Tours and signage explain the sustainable features, providing inspiration for how to apply these principles at home. The creation of the American Veterans Disabled for Life Memorial next door to the park presented an opportunity to collaborate with the National Park Service, and educational and therapeutic programs for veterans and active duty soldiers were developed and now use this space. "USBG has championed SITES since our initial work in helping develop the program more than a decade ago. We are excited to now have Bartholdi Park as a living example of a sustainably designed garden right in the middle of Washington, D.C.," said Saharah Moon Chapotin, executive director, USBG. The story of the renovated Bartholdi Park is shared through new interpretive signage throughout the park. "Bartholdi Park's sustainable development serves as a model for communities looking to build a healthy and prosperous future for residents and visitors," said Mahesh Ramanujam, president and CEO, USGBC and GBCI.
