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…)

The things our art director, Chris McGee, hated to leave out of the current issue of LAM.

West Point Foundry Preserve winter aerial by Elizabeth Felicella.

Extra from “A Past, In Pieces” by Jennifer Reut, in the April 2015 issue, featuring Mathews Nielsen Landscape Architects.

 “I love the angle of this aerial, which is enhanced by the long shadows under a low-hanging sun. The effect is a feeling of motion—of swooping low over the bare canopy. The red brick building at the bottom is an anchor that holds the image in place and creates a static ‘yin’ for the motion’s ‘yang.’

—Chris McGee, LAM Art Director
