In Southern Louisiana, Evans + Lighter Landscape Architecture is helping the people of Isle de Jean Charles move away from a disappearing coast.

Every year LAM honors two articles that stand out in the realm of landscape architecture with the Bradford Williams Medal—one that has appeared in LAM, and one from outside the magazine. After a nomination and selection process by the LAM Editorial Advisory Committee, this year’s 2017 Bradford Williams Medal LAM winner is Brian Barth for his article “Let’s Beat It,” below, which appeared in the October 2016 issue.

Wenceslaus Billiot often spies dolphins leaping in the bay behind his house in Isle de Jean Charles, Louisiana. Just shy of his 90th birthday, he remembers his backyard as a vast, forested wetland when he raised his family here as a young man. In dry weather, the land was firm enough for his kids to walk to the store in the nearby hamlet of Chauvin. This June day the water is calm—a fisherman’s paradise—but hurricane season is another story. Billiot, a World War II veteran, former tugboat captain, and boat builder, says every year the water comes higher.

He lives in a dwindling community of the Biloxi–Chitimacha–Choctaw tribe, and like most of the 27 families who remain, Billiot and his wife, Denecia, are making plans to move inland. “But I don’t want to go,” he says in a Cajun accent.

He has no choice. Isle de Jean Charles, once 22,000 acres, has lost 98 percent of its land area since 1955, and state officials warn that (more…)

The new Mosholu Golf Driving Range is part of a controversial water filtration plant project built at the edge of the bucolic Van Cortlandt Park.

The new Mosholu golf driving range is part of a controversial water filtration plant project built at the edge of the bucolic Van Cortlandt Park.

From the July 2016 issue of Landscape Architecture Magazine.

Many things are not exactly what they appear to be at the new Mosholu golf driving range, located in the northwest section of the Bronx in New York City. Behind high stone walls and a gate monitored by armed policemen there are carefully crafted illusions worthy of an Olmsted design. A driveway leading into this place looks as if it were carved out of wilderness. On either side are sunken beds of untamed riparian plants that pool with water after rainstorms. Up a slope, past a low-slung building faced in rust-colored steel, you are at the high point of the range. The greens below are composed of hillocks with carpets of turfgrass, plush enough for a nap, which overlook a bowl-shaped depression.

Beneath the driving range is the Croton Water Filtration Plant. At a cost of more than $3.2 billion, it is among the most expensive public works projects ever built in New York City. The driving range sits atop a nine-acre green roof covering the plant, which is said to be the country’s largest contiguous green roof. It replaces an old municipal driving range bulldozed more than a decade ago to make way for the underground filtration plant, which descends about 100 feet into the ground. The subterranean structure is designed to filter up to 30 percent of New York City’s water supply.

The need to purify water, especially water that humans have polluted, has become (more…)

Milwaukee pilots a new stormwater management tool.

Milwaukee pilots a new stormwater management tool.

From the July 2015 issue of Landscape Architecture Magazine.

By August, the faded yellow house at 3930 North 35th Street in Milwaukee will be gone. In its place, invisible to all but the team that designed it, will be a new tool for stormwater management: the “BaseTern.” Conceived by Erick Shambarger, the deputy director of Milwaukee’s Office of Environmental Sustainability, a BaseTern is a basement that’s been converted into a rainwater or stormwater cistern. Milwaukee is completing what is said to be the world’s first such system this month.

The BaseTern concept, which Shambarger trademarked, is simple. Stormwater will be directed to an abandoned or foreclosed property’s basement, which, after the aboveground structure is demolished, is waterproofed and filled with gravel and stormwater-harvesting cells. According to a feasibility study by engineers at HNTB, the system can hold anywhere from 13,000 to 40,000 gallons of water during storms, reducing flooding in adjacent homes.

It’s a clever riff on adaptive reuse, taking advantage of one urban issue—a surplus of city-owned foreclosures—to solve another: the flooding that is increasingly common in dense, impervious neighborhoods like Milwaukee’s Sherman Park, where the pilot project is located.
