FROM THE MARCH 2021 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

On August 29, 2005, the world saw what happened when a levee failed. A Category 3 hurricane slammed the Gulf Coast, 169 linear miles of federally constructed levees collapsed, and nearly 80 percent of New Orleans flooded, killing almost 1,000 people, the majority of them African American and over the age of 65. It was a wake-up call not just for New Orleanians but for lawmakers 2,000 miles away in California, who worried about their own state’s intricate system of ancient levees, which hold back the waters of the Sacramento–San Joaquin Delta.

Covering an area the size of Rhode Island, the Sacramento–San Joaquin Delta is an inland delta formed by the confluence of five major waterways, including the Sacramento and San Joaquin Rivers. It stretches from just east of the San Francisco Bay north to Sacramento and south to Stockton and drains more than 50 percent of the state of California. It is also a highly engineered landscape, made up of winding canals, earthen levees, and terraced agricultural fields. Roads follow the sinuous levees, forming what, from the air, appears as a convoluted puzzle pieced together over eons by a deranged dissectologist.

The delta’s present-day morphology is the product of one of the largest land reclamation projects in U.S. history. In the late 19th century, farmers and land speculators drained more than 500,000 acres of wetlands in the delta, using the dredge material—much of it the spoils of industrial gold mining—to build human-made islands. In the 20th century, water conveyance projects such as the California State Water Project further severed the relationship between delta wildlife and its unique hydrology. “There is nothing about the delta that is like what it used to be,” explains Brett Milligan, an assistant professor of landscape architecture at the University of California, Davis, and a cofounder of the Dredge Research Collaborative. “The way water flows through it is entirely different. The channels have been widened; all the dendritic channels have been cut off. There’s no floodplain at all.” (more…)

In Chicago, a synthetic growing medium will provide a healthy buffer between contaminated soils and riparian plant life.

 

For nearly 100 years, the Morton Salt facility on the North Side of Chicago, with its massive rain slicker and umbrella sign, has been an iconic presence along the industrial corridor that traced the North Branch of the Chicago River. The warehousing and packaging facility closed in 2015, and within a few years, the company announced an ambitious adaptive reuse plan for the site, turning it into a mixed-use campus featuring a concert venue and office spaces. (The sign will stay.) It will also be home to Morton’s R&D facility, relocating from Chicago’s suburbs, where the company will research water softener salt, pool salt, deicing salt, and salt solutions for other industrial applications.

The project’s innovation will extend to the outdoors: The landscape of the campus will include a synthetic growing medium developed by Omni Ecosystems. According to the company, it’s the first site in Chicago that’s been approved for the use of special stormwater soils designed to mitigate runoff and stormwater from combined sewer overflows. Working with the Chicago Plan Commission and the Department of Buildings, Omni Ecosystems will use 60,000 cubic feet of Omni Infinity Media, largely composed of an ultra-light, kiln-dried mineral similar to volcanic rock. This medium will allow a rich wetland and riparian ecosystem to thrive on top of a degraded and polluted site that’s been capped with concrete and asphalt.

The Omni Infinity Media is mostly air—it has 78 percent void space, compared to standard topsoil, which has 25 percent. “It’s quite literally and physically a sponge,” says Michael Skowlund, ASLA, the director of landscape architecture at Omni Ecosystems. (more…)

The things our art director, Chris McGee, hated to leave out of the current issue of LAM.

Image by Florence Low for California Department of Water Resources.

From “Toward Reclamation” in the March 2021 issue by Timothy A. Schuler, about how federal recognition of a critical ecosystem in California where five waterways collide can maintain the Sacramento–San Joaquin River Delta’s cultural heritage and ecological integrity.

“Flooded fields on the delta.”

–CHRIS MCGEE, LAM ART DIRECTOR

FOREGROUND    

Cracking Up (Materials)
Concrete cracks inevitably, but there are steps designers can take to help alleviate stress.

FEATURES  

Toward Reclamation
A National Heritage Area designation brings the overlooked cultural history of
the Sacramento–San Joaquin River Delta, long seen as California’s plumbing system, to light.

The Big Deal
A small city in rural North Carolina finds itself with a lot of land to develop after a historic psychiatric hospital moves on. A landscape-driven plan by Stewart helps find 800 acres of potential.

A new landscape architecture docuseries goes behind the scenery.

FROM THE DECEMBER 2020 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

“It’s hard to tell the story of the L.A. River without flying through it,” says Michael Todoran, a landscape designer, lecturer, and podcast host. Along with his students at California State Polytechnic University, Pomona, in January Todoran began filming “Superfisky: The Allure of the Urban Wild,” the first episode of Larchitect, a docuseries devoted to landscape architecture. This in-progress episode focuses on Kat Superfisky, a landscape designer, ecologist, and educator working to restore the natural beauty and native plant life on the shores of the mostly concrete-lined waterway. When the landscape, specifically the Los Angeles River, is a supporting character in your story, visual exposition becomes critical. The best solution was a helicopter shot that showed the true breadth and boundless energy of this body of water. (more…)

Cornell students bring visions for climate adaptation down to the Hudson shore.

FROM THE MAY 2020 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

The Hudson River is tidal, gaining a mean elevation of only two feet for 150-plus miles inland from the Atlantic. It is flanked, almost without interruption, by bluffs and cliffs. Most communities along it have only a slender strip of land at river level. Historically, industries and infrastructure were sited below, with more salubrious parts of towns built up the slopes. Most industry is gone. Communities want to reinvent their riverfronts, which means contending with the tides and storms of a changing climate. They’re getting help from Josh Cerra, ASLA, the director of graduate studies in the Department of Landscape Architecture at Cornell University. With collaboration from the New York State Department of Environmental Conservation’s Hudson River Estuary Program, he has been bringing community-based “Climate-Adaptive Design” studios to Hudson River towns.

The studio has obvious pedagogical value. Students learn site research and engagement skills, and to imbue design with climate science. Meanwhile, it lets Cerra pursue an interest in applied education and cross-disciplinary experiences. In developing their concepts, his students get “consultants”—other students, from Cornell’s Department of Biological and Environmental Engineering. To assess the studio’s benefits, Cerra is collaborating with a Cornell researcher who studies behaviors and conservation management. Their inquiries, he says, include “how working with engineers or other technical partners may enhance learning innovation” for landscape architects. And then there is the studio’s value to the towns, which are gifted with provocative visions for their futures. (more…)
