An unprecedented storm that dumped more than 50 inches of rain onto Texas over just a few days, Harvey was the kind of hurricane that worsening climate change promises to bring back for a sequel. And if and when that happens, the next round of  recovery and resilience calculus might best begin with the results of the National Science Foundation’s series of research grants dedicated to studying the storm’s effects.

Last month, the agency handed out just over $5 million across 59 research projects prompted by Hurricanes Harvey and Irma, including several that deal with the ecological and landscape fallout of catastrophic storms. Each promises to generate valuable information about flora and fauna left reeling from extreme weather events. But these studies (four of which are detailed here) are even more vital as mile markers down the path toward a future besieged by climate change—either as guidance on forestalling it or living better within its confines.

Anna Armitage of Texas A&M Galveston is studying how the transition from salt marsh wetlands to mangroves might change how hurricanes affect the coast. In Texas, low, marshy wetlands are common, whereas dense mangroves are rare. That balance is shifting, however, as climate change heats up these ecosystems. As mangroves expand their footprint, Armitage (and researchers at Florida International University and the University of Houston) wonders if they might offer coastal ecosystems and human settlement more protection from hurricane winds and rain—at a cost of biodiversity. “It probably doesn’t provide the same value for birds, fish, and shrimp,” she says.

Climate Change Big Picture: If mangroves do offer more protection for coastal ecosystems in a climate of increasingly severe storms, then Armitage says the next question is, “Should we be planting them in restoration sites?” These kinds of “living shorelines,” she says, could be “more resilient, longer-lasting, and nicer looking protection for our communities” than concrete barriers.

Grant amount: $122,935

Paul Montagna of Texas A&M Corpus Christi is studying the inundation of fresh water (via rainfall) into saltwater ecosystems that Hurricane Harvey caused. From initial measurements after the rain, he’s observed increased amounts of dissolved organic matter in these waterways, and has seen (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…)

A sophisticated stormwater system elevates Philadelphia’s Girard Avenue interchange.

FROM THE NOVEMBER 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Around the world, cities are demolishing, burying, or capping their elevated freeways, but an interstate in Philadelphia provides a possible alternative—one in which the highway stays up but connectivity, open space, and water quality are still prized. In redesigning three miles of Interstate 95 north of Center City Philadelphia, the Pennsylvania Department of Transportation planned 27 acres of park and open space, and the first phase of the $1 billion project, due for completion by 2027, incorporates examples of green infrastructure. According to AECOM, the prime consultant on the project, landscape design and green infrastructure accounted for between 5 and 7 percent of the first phase’s total budget.

At the Girard Avenue Interchange, I-95 runs parallel to the Delaware River two blocks away. Rather than whisking stormwater runoff directly into the river, overtaxing an already burdened municipal system, or funneling a deluge into a rock pit, AECOM and other experts devised a treatment scheme of basins, weirs, bioswales, and rain gardens. Ten planted acres can capture the first inch of runoff (more…)

Technologist landscape architects rejoice—the November issue of LAM is packed with imagined scenarios, myth breakers, and tantalizing possible futures for urban design. Whether or not autonomous vehicles will allow for utopian cities of tomorrow depends on careful planning and policies today, says writer Brian Barth. And the future of autonomous vehicles might not look as green as we’re imagining. A new landscape by Ki Concepts on Honolulu’s Ford Island—site of the Pearl Harbor attack in World War II—weaves the richly layered history of the site into a sleek, cohesive design. And a new streetscape redesign by CRSA in the Sugar House business district of Salt Lake City turns a large thoroughfare into an inviting multimodal streetscape.

In Materials, Jane Berger discusses the stigma—and benefits—of the often-misunderstood bamboo. And in Tech, geodesign unites academics and agriculturists in the pursuit of the most optimal yield for their yearly crops. All this plus our regular Books, Now, and Goods columns. The full table of contents for November can be found here.

As always, you can buy this issue of Landscape Architecture Magazine at more than 700 bookstores, including many university stores and independents, as well as at Barnes & Noble. You can also buy single digital issues for only $5.25 at Zinio or order single copies of the print issue from ASLA. Annual subscriptions for LAM are a thrifty $59 for print and $44.25 for digital. Our subscription page has more information on subscription options.

Keep an eye out here on the blog, on the LAM Facebook page, and on our Twitter feed (@landarchmag), as we’ll be posting November articles as the month rolls out.

If the design of our environments is a text that can be used to decode hidden meanings and obscured institutional values and biases, then design is a tool that’s equally up to the task of picking apart these inequities. That’s the intent of the second edition of the Black in Design Conference at the Harvard University Graduate School of Design, subtitled “Designing Resistance, Building Coalitions,” and previewed by LAM earlier this month. Hosted by the Harvard GSD African American Student Union, the conference, held October 6-8, documents the effects of the African diaspora across the globe and the design fields, and questions the barriers and inhibitions to agency this community still faces. Its goal? More “radical and equitable futures.”

Across 10 hours of the conference, filmed and posted here, the organizers hear from a wide swath of design professionals, including planners, architects, artists, and landscape designers, such as Walter Hood, ASLA, and Diane Jones Allen, ASLA.

Mixed-income housing alone can’t change public housing residents’ lives. So Gary Strang is putting the landscape to work.

FROM THE OCTOBER 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Correction appended.

The first thing you notice is all the cars. The Potrero Hill housing projects occupy a strange landscape divided by Jersey barriers and concrete retaining walls that carve up the site’s topography. Endless rows of cars are parked along its curving streets and in front of 62 three- and four-story barracks-style buildings that step down the steep hill. It’s the first indication that this isolated, often forgotten section of the city is not that well connected to the thriving, upscale urbanism of San Francisco that surrounds it. “The beautiful green landscape, the Corbusian dream, just becomes parking,” says Gary Strang, FASLA, the founder of GLS Landscape | Architecture, the firm that was hired to radically reshape this place.

For Curteesha Cosby, who lives at Potrero, these parked cars are sometimes a refuge of last resort. When she’s walking her kids to school at 7:00 a.m. and hears gunfire, she hits the ground and rolls her children under them till it ends. She says she hears shooting nearly every day. She’s exhausted by Potrero. “I just want people to be happy and everyone to be safe,” she says. Her cousin was gunned down in the housing complex a few days before we spoke. Edward Hatter, the executive director of the Potrero Hill Neighborhood House, a nonprofit serving the area, tells me the community is waiting for the retaliatory violence that often follows shootings.

Potrero Terrace and Annex has long been one of San Francisco’s most dysfunctional large-scale public housing developments. Residents complain of (more…)

REVIEWED BY GALE FULTON, ASLA

FROM THE OCTOBER 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

To listen to some mainstream urbanists today, you have to wonder what body of theory, if any, they are paying attention to in order to make what often seem hopelessly naive and homogeneous proposals for new urban developments. Admittedly, this group is often the same bunch who don’t have time for impractical theorization because they are out there doing real work, but some idea about “good” city form obviously drives their approach. Unfortunately, many of the theories in circulation stem from a belief that the city is nothing more than a problem to be solved—it’s too dense, or not dense enough; gray and dirty rather than green; impervious and polluting; unjust and inequitable; or not living up to that crowning achievement of being “walkable.” Obviously, most if not all of these criticisms can be leveled at cities in one place or another at one time or another, but what are the implications for the urban imagination of designers if this is the only lens through which the city (arguably the greatest cultural artifact ever produced) can be viewed—a massive problem which must be “restored” to some nostalgic, fictional notion of the healthy city? And, more optimistically, what new propositions, pedagogies, and disciplinary alignments are necessary to overcome these narrow worldviews and begin to engage the phenomenon of urbanization in a more compelling and realistic way?

In his new book Landscape as Infrastructure, Pierre Bélanger, ASLA, an associate professor of landscape architecture and a codirector of the Master in Design Studies Program in Urbanism, Landscape, and Ecology at Harvard University’s Graduate School of Design, lays the groundwork for such an approach. Assembling a decade of design and scholarly research, Bélanger provides readers with a much-needed alternative history of urbanization (primarily in mid- to late 20th and early 21st-century North America), as well as a survey of the contemporary forces that drive urbanization patterns today. These aspects of the book are complemented by an account of the accompanying epistemological shifts brought about by new understandings of complexity and ecology as well as a resurgence of (more…)
