The Sustainable Sites Initiative (SITES) program has certified landscapes at a federal courthouse in New Mexico, an elementary school in Washington, D.C., a campus plaza in Washington, D.C. and an urban plaza in Washington state.
The four projects include the Albuquerque’s Pete V. Domenici U.S. Courthouse, which received a two star certification; Brent Elementary School in Washington, D.C., which received one star; Square 80 Plaza at The George Washington University, also in D.C. with one star; and East Bay Public Plaza in Olympia, Washington, with one star.
The newly certified projects applied the 2009 SITES Guidelines and Performance Benchmarks and met the requirements for pilot certification. There are now 30 landscape projects at universities, businesses and public spaces that have achieved this recognition.
These landscape projects include the following sustainable features:
- Pete V. Domenici United States Courthouse Sustainable Landscape Renovation, Two Stars, Rios Clementi Hale Studios,Albuquerque, N.M. This federal courthouse is the first project constructed by the General Services Administration to achieve SITES certification. Originally constructed in 1998, the underused hardscape plazas, overwatered lawns and faulty water feature of the existing courthouse exemplified resource inefficiency, disconnection from its environment, and distance from the public. The landscape renovation reconceives the site as a cohesive park-like landscape rooted within the rich cultural, climatic and hydrological fabric of the Rio Grande Basin. Innovative strategies include the selective removal and re-use of excess concrete paving to create seat wall terraces that direct site stormwater into a series of native habitat rain gardens. The project creates a bold landscape and dignified setting for court operations while enhancing the efficiency and sustainable operations through improved water management, decreased energy use and increased urban habitat.
- Brent Elementary Schoolyard Greening, One Star, Sustainable Life Designs, Washington, D.C. Located five blocks from the nation’s Capitol, this greyfield site with asphalt-dominated grounds was transformed into a sustainable landscape that educates students, parents, and neighborhood residents about green infrastructure. Improvements include the removal of 1,600 square feet of asphalt and the installation of pollinator gardens, stormwater management features, new play equipment, and 7,000 square feet of outdoor classrooms to enhance outdoor play and learning that were achieved through numerous volunteer hours. The stormwater management features include a rain garden, rain barrel, and bio-retention swale. A formerly trash-strewn space behind the school building is now an “urban canyon” that helps manage stormwater and provides native habitat.
- Square 80 Plaza at The George Washington University, One Star, Studio 39 Landscape Architecture, Washington, D.C.The Square 80 Plaza project converted an existing parking lot into a park that creates pedestrian connections and open space at an urban university campus. The project retains 100 percent of its stormwater runoff on site through the use of biofiltration planters, permeable paving, hardscape diversion through use of small channels, and the collection of site water into a system of inter-connected cisterns. All plants used on the site are native and adapted species, and all water used for irrigation and the sculptural water feature is fed by the rainwater collected in the cistern, which uses no potable water.
- East Bay Public Plaza,One Star, Robert W. Droll Landscape Architect, Olympia, Washington. East Bay Public Plaza is a vibrant public urban space located in the Puget Sound region that showcases the benefits of reclaimed water and the efforts of the LOTT Alliance, an Olympia-based wastewater treatment company. The former brownfield includes new educational elements such as discovery markers, interactive stream features, a series of interpretive panels, and a ground plane timeline that playfully charts the past, present and future of reclaimed water to inspire and inform visitors.
