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…)

FROM THE NOVEMBER 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

In March of 2016, the landscape architect Ron Henderson, FASLA, had the rare opportunity to visit Mcity, the autonomous vehicle research center at the University of Michigan in Ann Arbor. His entourage, which included Nilay Mistry, ASLA, as well as an architect, a transportation engineer, a social scientist, and an attorney, signed in at a gatehouse worthy of a military facility. They were then relieved of all cameras and recording devices—“It’s like a top-secret corporate espionage kind of place,” Henderson says—before being escorted on a brief tour of a 16-acre test track composed of every road condition imaginable: bridges, tunnels, gravel roads, bike lanes, railroad crossings, roundabouts, graffiti-defaced road signs, faded lane markings, a main street with parallel parking, and a short stretch of freeway. “They even have a little Potemkin village of fake storefronts,” Henderson says.

At Mcity, a consortium of academic researchers, government agencies, and corporate entities are sorting out how to make autonomous transportation a reality. Henderson was surprised to learn that trees may not be part of the equation. “We learned that vegetation interferes with the signals between the cars,” he says. “So they cut down the trees at the test track. One of the engineers jokingly said to us, ‘If we had our druthers, we would just cut down all the trees.’ The landscape architects in the group (more…)

An asphalt coating could help cool Los Angeles. Will the benefits offset the costs?

FROM THE OCTOBER 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Initially, the product was for the military. Marketed as CoolSeal, the light gray-colored asphalt seal coat was developed to reduce the surface temperature of runways so that they would be less visible to infrared satellites. A few years ago, Greg Spotts, the assistant director of the City of Los Angeles Bureau of Street Services, wondered what would happen if you painted every street in the city with CoolSeal. Could you reduce the urban heat island effect, a phenomenon that has been estimated to cost the city $90 million each year in energy bills?

Now, with $150,000 in public funding, Spotts is testing the coating at locations in each of the city’s 15 council districts. The coating, which is just 15 microns thick, goes on in a brilliant gray, far lighter in color than a typical asphalt street, though Spotts says it soon fades to more of a “battleship color.”

By this fall, all 15 streets should be complete, and according to the city’s asphalt testing lab, even in the afternoon on the hottest days, the surface temperature of the coated pavement is, on average, (more…)

Marijuana wafts across the California landscape as legalization of recreational use approaches.

FROM THE OCTOBER 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Ed Rosenthal grows weed. He has for decades. The Oakland, California-based horticulturist, author, and activist is the go-to expert on home cultivation. He’s written more than a dozen books on the subject and the policies that surround medical marijuana and legalization. Their titles fall somewhere between what you’d see in your local nursery and your corner head shop: The Big Book of Buds (volumes one through four), Marijuana Garden Saver, and Marijuana Pest & Disease Control.

“Growing is addictive,” Rosenthal says with a laugh, and then quickly clarifies that the drug is not. “Given the right conditions and a sunny backyard, marijuana can be grown almost anywhere in California.” He speaks poetically about marijuana’s diverse morphology: It has male and female plants. Some are tall, some wide, and there are different strains like indica or sativa that range in color—like heirloom tomatoes—from absinthe yellow–green to maroon and deep purple. To cultivate cannabis for its THC (tetrahydrocannabinol) and psychoactive properties, only the female plants are grown. The male plants look a bit like wild mustard; the female plants are the ones that produce buds for consumption. “With humans and cannabis, the female is considered more beautiful,” he explains. “I have a bunch of marijuana plants growing, and they all look different, like six different varieties of a dahlia. Each plant is (more…)

Los Angeles is an intriguing place for 2017’s ASLA Annual Meeting and EXPO. It’s a car-centric metropolis in the throes of a rebirth in public transportation, a drought-parched region with a remarkably complex water infrastructure, and an image-conscious city with a deceptively robust urban foundation. The October issue celebrates the ASLA Annual Meeting with a look at Los Angeles’s, and California’s, big designs on the future.

Christopher Hawthorne’s Third L.A. Project brings to the forefront issues, including density and equity, that Los Angeles—and Angelenos—face with the reinvention of the sprawling, single-family-home-dominated city. Waving away the clouds of optimism around marijuana legalization and production, Mimi Zeiger investigates the costs and benefits to the landscape. And in a city where entertainment is king, Studio-MLA goes big with three sports stadium projects in the Los Angeles area.

Up the coast, a public housing project on San Francisco’s Potrero Hill gets connected to the city by GLS Landscape | Architecture, while trying to stave off gentrification that could follow. And AECOM’s work on the South San Francisco Bay restores ecosystems once battered by the salt industry back to their natural habitat.

Glen Dake, ASLA, talks about his firm’s commitment to resiliency and “meeting people in their language,” in Interview. Two gardens at the storied Garden Museum in London get a redesign by Dan Pearson and Christopher Bradley-Hole in Plants. A remediation plan by Fred Phillips for an Indonesian tin mining site includes providing an alternative livelihood for artisanal miners, in Planning. And in Palette, subtle layers compose the designed landscapes of Pamela Burton & Company Landscape Architecture. All this plus our regular Books, Now, and Goods columns. The full table of contents for October can be found here.

The DAPL crosses two watershed systems. Map by Alma and Friends.

The recently completed Dakota Access Pipeline (DAPL) will run for 1,172 miles from northwest North Dakota to downstate Illinois, pumping 450,000 barrels of oil per day and costing $3.8 billion to build. Those are superlative numbers that can blot out the complexity and vulnerability of the landscapes and watersheds the pipeline traverses. Making these facets of the DAPL clear is the goal of maps created by an anonymous group of designers calling themselves Alma and Friends. Their work has been collected and packaged by the Los Angeles public television station KCET with a series of articles on the ecological consequences of the pipeline.

These maps detail regional watersheds, individual bodies of water, indigenous lands, the blotches of human settlement that dot this stretch of the Great Plains and midwestern prairie, and past and potential oil spills. Collected into a series of seven interactive maps by KCET, (more…)
