The stone industry adopts a new sustainability standard.

FROM THE FEBRUARY 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

In 14 Patterns of Biophilic Design, Bill Browning, an environmental designer and founder of Terrapin Bright Green, cites “material connection with nature” as a significant principle. In other words, materials from nature, with minimal processing, can be used to construct the built environment—reflecting the local geology and connecting people to a place and natural setting. More than any other material, stone fulfills this “pattern”—often seamlessly settling a built landscape into the larger natural context. Yet in some cases, heavy stone can travel thousands of miles between harvest and use—offering absolutely no connection to the local natural landscape and creating a substantial environmental footprint.

Stone holds great potential to be a highly sustainable construction material for use in paving, stairs, and walls. It can be extremely durable, with relatively low embodied energy (energy used to produce a material), and nontoxic. However, a study from the University of Tennessee estimates that more than half of all dimension stone—defined as any stone that has been cut or shaped for use in construction—is imported, primarily from China, India, and Brazil, owing to far lower labor costs and fewer worker safety regulations, which combine for a lower product cost. Some of this stone might have been harvested in the United States, sent overseas for processing, then returned as “imported stone.” Minimal records of stone harvest, sales, and processing make it challenging to track stone’s path to market. Additionally, environmental impacts from waste and water use in stone quarrying and manufacture are not insignificant. Fortunately, a new standard from the Natural Stone Council (NSC) and the American National Standards Institute (ANSI) offers criteria for reducing the environmental impacts of stone harvest and processing and requires a chain of custody for stone so consumers can know for sure the path their “local” stone has traveled.

The stone quarrying process is often lumped together with metal mining’s heavy blasting and toxic runoff, but Kathy Spanier, the marketing director at Coldspring in Minnesota and a participant in the development of the new stone standard, emphasizes (more…)

Renowned for their ad hoc flexibility, material economy, and compositional resourcefulness, Rio de Janeiro’s favelas can be treasure troves for urbanists. Unplanned, unsanctioned, and often unmapped, they mutate (adding a story, turning a ground floor into a shop, switching from sheet metal to concrete as soon as owners come into a few more Brazilian reals) at a pace unseen in the affluent global north. But these communities are located far away from most of the world’s stock of urban design expertise.

Last spring, to bridge this divide, Penn State landscape architecture professor Timothy Baird and architecture professor José Duarte taught a new studio that engaged students in the study of one Brazilian favela via virtual reality (VR) technology. The studio, which paired architecture students with landscape architecture students, posited VR as a proxy for expensive site visits. “Developing countries can’t always afford consultants because of the distance and difficulty to travel,” says Baird, who recently became chair of the landscape architecture department at Cornell University.

The virtual reality environment in which these students designed was constructed after Duarte and a crew of Brazilian students traveled to Rio de Janeiro’s Santa Marta favela before the semester began. They took thousands of still images, 360-degree videos and photos, and collected (more…)

Promising new alternatives to tropical hardwoods come with caveats.

FROM THE APRIL 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE

The past decade has brought an explosion in the use of tropical hardwood decking and furnishings in public, institutional, and commercial landscapes. Whereas wood decking was once largely the purview of residential landscapes, now it can be found in urban settings from the High Line to West 8’s sculptural Wavedecks. Tropical hardwoods are so durable, hard, and decay-resistant that they appear to be the ideal material, yet the impacts of using even hardwoods certified by the Forest Stewardship Council can be substantial and threaten the most critical ecosystems of our planet.

Wood is a renewable construction material if you compare the amount of time a wood member is in use to the amount of time it takes to grow a tree to yield a comparable piece. But that is not always the case. For example, it takes 90 years to grow a Handroanthus heptaphyllus tree to yield ipe lumber for deck boards, but the deck boards will likely not be in use for 90 years even if they are reclaimed, refinished, and reused.

As concern for the health of tropical forests is increasingly recognized in sustainable design thinking, alternatives to tropical hardwoods (more…)

Milwaukee pilots a new stormwater management tool.

Milwaukee pilots a new stormwater management tool.

From the July 2015 issue of Landscape Architecture Magazine.

By August, the faded yellow house at 3930 North 35th Street in Milwaukee will be gone. In its place, invisible to all but the team that designed it, will be a new tool for stormwater management: the “BaseTern.” Conceived by Erick Shambarger, the deputy director of Milwaukee’s Office of Environmental Sustainability, a BaseTern is a basement that’s been converted into a rainwater or stormwater cistern. Milwaukee is completing what is said to be the world’s first such system this month.

The BaseTern concept, which Shambarger trademarked, is simple. Stormwater will be directed to an abandoned or foreclosed property’s basement, which, after the aboveground structure is demolished, is waterproofed and filled with gravel and stormwater-harvesting cells. According to a feasibility study by engineers at HNTB, the system can hold anywhere from 13,000 to 40,000 gallons of water during storms, reducing flooding in adjacent homes.

It’s a clever riff on adaptive reuse, taking advantage of one urban issue—a surplus of city-owned foreclosures—to solve another: the flooding that is increasingly common in dense, impervious neighborhoods like Milwaukee’s Sherman Park, where the pilot project is located.

July’s LAM looks at the long-needed rehabilitation of Babi Yar Park, a memorial ground in Denver dedicated to the lives lost in Kiev, Ukraine, during the Holocaust, by Tina Bishop of Mundus Bishop; a rethinking of Chavis Park in Raleigh, North Carolina, by Skeo Solutions, which embraces the park’s African American heritage through public engagement; and the ground-to-crown planting of the One Central Park high-rise in Sydney, designed by Ateliers Jean Nouvel, with Aspect | Oculus and Jeppe Aagaard Andersen, where sprawling green balconies make what is said to be the tallest vertical garden in the world.

In this month’s departments, the Milan Expo 2015 centered on food sustainability seems to draw controversy from every angle; Molly Meyer is leading the charge for affordable, simpler, and greater biodiversity in green roofs; and nature reclaims lands once lost from the demolition of two dams on the Elwha River in Washington State. In The Back, an exhibit at the Smithsonian National Museum of Natural History immerses visitors in the beauty of Iceland through sight and sound. All this plus our regular Now, Species, Goods, and Books columns.

The Headland Park at Barangaroo Sydney, designed by PWP Landscape Architecture, is scheduled for its formal opening this summer. It is a total re-visioning of what was once a one-kilometer concrete slab described as the “third runway at Sydney airport” into an organic waterline reminiscent of its original form when Aboriginals inhabited the area. This nearly four-minute video, presented by Barangaroo Sydney, describes the multidisciplinary approach to the project and the separate components, from the sandstone hewn from the site to the native vegetation selection, that create a place unique to Sydney. Separately, an interview with Peter Walker in 2010 goes into detail on the design decisions for the iconic landscape, as well as what the design elements mean for Barangaroo and Sydney. For a more promotional video detailing the history of the site to the present, visit here.
