FROM THE MAY 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

The Harahan Bridge, which crosses the Mississippi River at Memphis, Tennessee, opened in 1916. Down its center ran railroad tracks. Cantilevered off each side was a 14-foot-wide “wagonway” for cars, trucks, horse carts, and pedestrians. This bridge is what’s called a through truss, with a latticelike steel superstructure like something from a giant Erector Set. The two outboard roadways, however, were originally planked in wood. Trains tend to throw off fragments and sparks—and not just antique ones that blew fiery debris from their smokestacks. “It’s like shrapnel,” says the landscape architect Ritchie Smith, ASLA. “Rocks, nails, anything that’s on those tracks just gets pulverized, and can even be inflamed.” In 1928, the Harahan’s wagonways caught fire and burned out of control. “They had all the water you want 120 feet below, but no way to siphon it up,” he says wryly. Rebuilt, the Harahan continued to convey motor traffic until a highway bridge opened nearby in 1949. The wagonway decking was removed. Then, until recently, only trains used the bridge—officially. “There are all kinds of people who, when they were kids, would try to go walk across it. How tempting was that?” asks Lissa Thompson, ASLA, a coprincipal at Smith’s Memphis firm, Ritchie Smith Associates.

Tempting indeed. Anybody willing to clamber out along the exposed girders could have been rewarded with (more…)

In 2014 alone, 22 billion gallons of untreated sewage and stormwater made its way into the Great Lakes, according to the Great Lakes Commission. On its way there, this stormwater degraded the rivers and streams it flowed through and caused flooding in areas where hard surfaces terminally halt its infiltration.

To deal with this regional calamity, the Great Lakes Commission and Lawrence Technological University have launched a new initiative to disseminate technology and techniques that can mitigate untreated stormwater pollution, the Great Lakes Stormwater Technology Transfer Collaborative.

This partnership between the Great Lakes Commission, a Michigan-based nonprofit that works to protect the ecology and economic health of the region in the United States and Canada, and Lawrence Tech’s Great Lakes Stormwater Management Institute will leverage the commission’s widespread industry contacts with the school’s technical expertise.  (more…)

A map of Vilnius, Lithuania, produced in Russia at the tail end of the Soviet era, details the speed of the Neris River’s flow (1.8 miles per hour), its depth and width, and that it had a sandy riverbed. In addition, it reveals the dimensions of a nearby bridge, what it’s made of (concrete), and how much it can carry (55 tons). Across the Cold War divide, on Western shores, Soviet cartographers still had a grasp of some of the minutiae that made up its sworn rival’s infrastructure. A 1980 map of San Francisco points out that the Oakland Bay Bridge is constructed of metal and rises between 171 and 213 feet above the water. One of perhaps a million maps made by the Soviets to secretly and conclusively chart the surface of the earth, it’s a relic from what might be the largest and most ambitious cartography effort in history.

Though much of this story’s origins and methods are shrouded in secrecy, British authors and map enthusiasts John Davies and Alexander Kent have found a way to break open these mysteries with a beautiful and brief cartographic volume. Their book, The Red Atlas: How the Soviet Union Secretly Mapped the World (University of Chicago Press, 2017), focuses on how these maps (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…)

AECOM’s plan turns the riverbed into an outdoor activities park. Image courtesy of the City of Los Angeles Bureau of Engineering and AECOM.

The big conundrum of the Los Angeles River—that it is so imposing yet so divorced from the city—shows in the visions for its future proposed in early June by seven architecture, engineering, and landscape architecture firms. The occasion was the Los Angeles River Downtown Design Dialogue, a pro bono charrette that took place on the 10th anniversary of the city’s original master plan for the river. The design firms showed ways that visitors could step down to its shallow waters, although the concrete-lined waterway runs so low at times it can seem more like a quasi-natural splash pad. But the most fascinating plans marginalized the typically modest amounts of water in the river almost entirely.

There are no immediate plans to execute any of the projects. Rather, Gary Lee Moore, the city engineer of Los Angeles, described the charrette as an opportunity to (more…)

The genius temporum of Martí Franch’s Girona landscapes.

FROM THE JANUARY 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE

“I really want to make the whole city like this,” says Martí Franch of Estudi Martí Franch (EMF), speaking of his vision of designing the green infrastructure of Girona, Spain, through a process of enlightened and engaged landscape management. We are sitting in his office, among shelves full of models and a table full of drawings. With us are Marc Rosdevall, a landscape architect with the City of Girona and the project’s director, and Marta Costa-Pau, a reporter from the local newspaper who is eager to report on the most recent transformations EMF’s work has wrought on Girona, and, in an amusing bit of journalistic circularity, to interview me to find out why this work is of interest and important to an American journalist and his landscape architecture audience.

Girona is a city in Catalonia with a population of roughly 100,000, situated in the rocky green foothills of the Catalonian Coastal Ranges at the confluence of four small rivers. The landscape is typical scrubby Mediterranean maquis, studded with stone pines (Pinus pinea), holm oaks (Quercus ilex), and the inevitable and omnipresent formal Italian cypresses (Cupressus sempervirens), which have an air of nervous, attendant stiffness in the loosely informal Catalonian landscape, like butlers at a barn dance. When I visit in late spring, (more…)

The 2008 flooding in eastern Iowa saw the Cedar River crest at 31 feet, inundating much of downtown Cedar Rapids. Image courtesy of Sasaki.

On the morning of Jun 12, 2008, the landscape architects Gina Ford, ASLA, and Jason Hellendrung, ASLA, of Sasaki woke up in their hotel rooms by the riverside in downtown Cedar Rapids, Iowa, to stifling heat and eerie silence. They were in town to pitch their riverfront master plan to the city council. They knew the Cedar River was expected to flood (and had stocked up on water, granola bars, and bananas just in case) but neither expected any sort of ordeal stemming from the river, which they had come hoping to reimagine as a lively and gregarious urban greenway. The power, air-conditioning, and phones were out. The hallways were empty and pitch black, and a ferocious rainstorm had darkened the skies and pushed the encroaching floodwaters. Reaching each other via cell phone, they discussed their options. In the distance, the Quaker Oats cereal mill plant’s red neon sign was still lit. “It can’t be that bad,” said Hellendrung. “They still have electricity.”

“As I said that, there was a bolt of thunder and lightning, and the sign went out. Then I was like, ‘Maybe the police will get here soon?’”

Police did dispatch rescuers, who led Ford and Hellendrung out of the hotel. A second-floor connection to the convention center (more…)
