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…)

Research at the Ohio State University aims to keep stormwater sediment stranded on the road.

 

When Halina Steiner tested new sediment-collecting infrastructure in her lab at the Ohio State University (OSU), she noticed a mysterious magnetism pulling people toward the bits of beveled foamboard she had crafted into sediment collectors. As water mixes with dirt and sand starts flowing across the planks of foam, and sediment settles into intricately carved CNC-milled grooves, “it’s very mesmerizing,” Steiner says. It’s like sending a paper boat down a stream or, more accurately, “down the gutter,” she says, because that’s the exact place Steiner is looking to intercept sediment that pollutes and clogs waterways.

This December LAM is under (and around and in) water. The feature well is saturated with new ideas about designing with and through water. The Port of Baltimore is open to designing with its dredge materials and has green-lit a pilot project for Mahan Rykiel’s sustainable and social enhancement of the Chesapeake’s Hart-Miller Island. Along the lakeshore, Chicago’s Navy Pier is putting aside its tourist-magnet past, with a redesign by James Corner Field Operations that now attracts native Chicagoans and visitors alike. And a handful of local efforts aim to combat the persistent encroachment of sea-level rise in the vulnerable communities surrounding Hampton Roads, Virginia, one of the most important strategic sites in the United States.

In Water, the EPA’s Campus RainWorks Challenge draws out creative solutions from landscape architecture students for treating and managing stormwater. Four landscape architects discuss the benefits and challenges of working in multidisciplinary firms in Office. In Materials, a quirky relic of an industrial past gets a glittery makeover for a Seattle park. And this year’s Landslide campaign from the Cultural Landscape Foundation calls attention to public landscapes and national monuments in immediate danger of erasure. All this plus our regular Books, Now, and Goods columns. The full table of contents for December 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.

An iconic Robert Moses-designed park on Long Island gets a resilient rethinking.

From the November 2016 Issue of Landscape Architecture Magazine 

 

I’m standing on the boardwalk at Jones Beach State Park in Wantagh, New York, with Faye Harwell, FASLA, a codirector of Rhodeside & Harwell. Our backs to the Atlantic, we look out over a flat expanse that used to be covered by shuffleboard, ping-pong, and tennis courts. Now it’s a mountain of broken-up concrete. By next summer, this will be a rolling naturalistic setting, dotted with a rock-climbing wall, zip line, splash pool, and, yes, a couple of shuffleboard courts, too. It will be the most visible of the many changes taking place at Jones Beach in a $65 million project undertaken by the state’s Office of Parks, Recreation, and Historic Preservation and guided by a report from Harwell’s firm.

Changes are needed. Built by the urban planning czar Robert Moses in 1929 as part of an unprecedented network of parkways and public parks, Jones Beach once was a six-and-a-half-mile-long marvel along the south shore of Long Island. Moses had used dredged sand to connect several small barrier islands, on which he and the landscape architect Clarence Coombs laid out the park (more…)

For the cover story of LAM’s August issue, Jennifer Reut, an associate editor at the magazine, goes on safari in Louisiana with the Dredge Research Collaborative, a loosely joined group of designers and one journalist spellbound by the huge, hidden power of dredging waterways for shipping or flood control, and all of its odd side effects. It began as almost a science fiction-type pursuit, though one member of the collaborative, Tim Maly, explains, “As we began to research the present of dredge, our wild ideas were routinely falling short of reality.”  Also in this month’s features, Jonathan Lerner surveys the outsized ambitions of Joe Brown, FASLA, who just retired from AECOM, the multinational design firm to which he welded the fortunes of the beloved landscape architecture firm EDAW in an acquisition nine years ago—to applause that was scarcely universal. And on the riverfront of Newark, Jane Margolies explores the degrading past and the brighter future of an old industrial site turned into Riverfront Park, with a boardwalk done in sizzling orange, by Lee Weintraub, FASLA.

In Foreground, we have the refashioning of certain large green roofs into farms; the balancing of goodness and financial prudence required to make social-impact design viable; and the layered dynamics of marine spatial planning as practiced by Charlene LeBleu, FASLA, at Auburn University. In Species, Constance Casey writes about the respectable labors of the mole—even if it can be a gardener’s scourge. In the Back, landscape architects in Denver suggest their personal favorite spots to visit during the ASLA Annual Meeting and EXPO in November. And of course, there’s more in our regular Books and Goods columns.

This winter, we wrote about the inaugural outing of the North Coast Design Competition (NCDC), Designing Dredge: Re-Envisioning the Toledo Waterfront, and now the winners have been announced. The entrants were asked to envision a useful waterfront space that combined existing and future outdoor developments with dredged materials, and also to provide the placement and design of a research site for the testing and experimentation of dredge material among other possible uses. Garrett Rock’s winning proposal, Re-Frame Toledo, would use Toledo’s dredge material to create sites for the public while also suggesting a phytoremediation step in the dredging cycle to process the sediment for future land use and better water quality. Sean Burkholder, an assistant professor of landscape and urban design at the State University of New York at Buffalo and the founder of NCDC, said that each of the 21 entries showed a thorough understanding of the subject. Some dealt with the excess sediment associated with dredging by creating riverside parks and recreation; others sought to create new ways of dealing with this material.

The Fluid and the Solid TRAILER from Alex + Ben on Vimeo.

If you haven’t used the term “Anthropocene” much, you can be forgiven. The term is of fairly recent origin, and it’s used to describe what some believe is a new geologic age: one in which human activity has changed the earth and its atmosphere. It’s a big idea, one that catches a lot of other ideas in its net—climate change being the most powerful. The idea of the Anthropocene lends more weight to what we already understand are the consequences of human activity. Our impact is not just local, national, or global, but temporal. We’ve literally changed the scale of geologic time.

The awesome consequences of human agency on the land are tough to convey without sounding ponderous, but for the filmmakers Alex Chohlas-Wood and Ben Mendelsohn, who are interested in things like infrastructure, technology, and the human/nature interface, much of the story can be told by the landscapes where these earth-changing processes take place. Which is how they came to make a documentary nominally about dredging, dredge landscapes, and sediment flow: The Fluid and the Solid.
