Large trees and steep slopes can work together—but it takes thought.

FROM THE APRIL 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

It’s interesting to watch the evolution of planting design alongside our profession’s affection for steep slopes. Using steep landforms allows us, as designers, to create dramatic rooms in small places. In any urban environment, the use of landform has become increasingly important to expanding our environment without increasing the square footage of its footprint. Slopes greater than 3:1 have become the sweetheart of the landscape architecture world—­and the steeper the better.

As space becomes smaller and landforms become steeper, clients are requesting larger plants that provide an instant landscape. The bigger the tree or shrub, the better. So we see a lot of enormous plants placed into sharp slopes as a standard practice.

In our practice, we’ve seen steep landforms become a challenge for contractors when installing large root balls, trying to establish the plants, and maintaining them during the warranty period. We’ve also seen misunderstandings among designers over the relationship between (more…)

LAMCAST: COMPUTATIONAL ECOSYSTEMS

University of Virginia Landscape Architecture Chair Bradley Cantrell, ASLA, sees the future of landscape design as a spectrum of interactions between technologies that sense the environment, model and simulate it, and then finally affect the physical world—all without constant human input and monitoring. As argued in his March 13 LAM Lecture (and in his recent book Responsive Landscapes, written with Justine Holzman, ASLA), the future of landscape architecture is one of designing protocols for how natural systems behave, and tuning these algorithms and eventually the land itself, thus loosening the stranglehold static and monofunctional infrastructure has on the planet.  “It’s not about us controlling every aspect,” he says. “It’s about us setting a range of ways those behaviors can act within.”

Cantrell’s research is grounded in the previous century’s cutting-edge modeling and simulation methods, like the Army Corp of Engineers Mississippi River Basin Model in Clinton, Mississippi, which modeled the entire rivershed, scaled down to a mere 200 acres. From there, Cantrell details contemporary research that is equal parts computational and material, honing ever more granular data points toward more accurate models. For example, there’s USC Assistant Professor Alexander Robinson’s Office of Outdoor Research, Landscape Morphologies Lab work, which uses an articulated robot arm to scrape out dust-mitigating landforms at California’s Owens Lake. Cantrell’s own inquiries involve test bed river basin models that deposit sediment via the variable flow of water, which he has been able to manipulate as though it were a geologic 3-D printer, expanding and cutting back sediment deposit “land” where it’s desired. The resulting topographies are scanned and converted into point-cloud maps.

Cantrell’s approach pushes landscape architecture’s prevailing infrastructure fixation until it ricochets out of the physically imposing world of concrete and culverts and into abstract data, underpinning the omnipresent ways we reengineer ecologies with quantitative facts. The biggest challenge for modeling and simulating dynamic environments, Cantrell says, is not gathering all the requisite data, but getting it to interact in a way that matches reality. At its core, it’s a call for new levels of observational rigor: first, to observe all the factors that make an ecosystem function, and then to understand how those factors work together to create a landscape.

BY MEG CALKINS, FASLA

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 JANUARY 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Iwanuma is a quaint and quintessentially Japanese beach town on the Sendai Coast, a two-hour train ride north of Tokyo, in Miyagi Prefecture. Rolling sand dunes line the coast, and a thin forest of black pines spreads inland to a wide band of rice paddies and modest farmhouses. Like dozens of small communities along this stretch of coast, it’s been farmed for hundreds of years, left mostly to itself as Japan developed and urbanized.

When the Great East Japan Earthquake pushed a tsunami against the coastline on March 11, 2011, Iwanuma was washed over by waves that rushed inland for miles and destroyed almost everything in their path. The parts of Iwanuma inundated by the tsunami were mostly agricultural lands, but the death toll still reached an estimated 180 people. In all, more than 15,000 people died as a result of the earthquake and tsunami. Most drowned.

It was a devastating catastrophe for a country all too familiar with disasters, natural and human-made. But it was also something of an alarm to many people in seismically hyperactive Japan who have become newly energized by efforts to prevent similar destruction from the inevitable tsunamis of the future. One approach has gained considerable attention: the accelerated planting of “forest walls” as wave barriers. Hundreds of thousands of saplings have been planted (more…)
