THE RISING TIDEWATER, REVISITED

BY BRETT ANDERSON / PHOTOGRAPHY BY SAHAR COSTON-HARDY, AFFILIATE ASLA

Disparate but urgent efforts to address sea-level rise in the Virginia Tidewater, one of the country’s most important strategic centers, are striving to keep up with visible realities.

Editor’s Note: Norfolk, Virginia, is both highly vulnerable to sea-level rise and a critical center of military and government infrastructure. As Hurricane Florence bears down on Virginia and the Carolinas, the risks associated with storm surge flooding are intensified by the region’s strategic importance. As Brett Anderson reported in the magazine’s December 2017 issue, this isn’t a new story, and landscape architects, academics, municipal officials, and residents are collaborating to find ways the region can respond to the inevitability of rising tides.

The first question that sprang to Ann C. Phillips’s mind soon after she moved to Norfolk, Virginia, in 2006 was, “Why, when it rains, does the whole place submerge?”

She wasn’t referring only to dramatic weather events, although Phillips, a retired rear admiral in the U.S. Navy, landed in Norfolk during a bumper crop of those: Norfolk saw more major coastal storms and hurricanes in the 2000s than in the four previous decades combined, according to the city government.

Harder to fathom were the floods caused by light rains and “blue sky floods” triggered by lunar tides. Tidal flooding affects low-lying areas of Norfolk nine times per year on average.

These more regular floods were unlike anything Phillips experienced growing up in Annapolis, Maryland. They’re an alarmingly routine part of life in Norfolk and the surrounding Hampton Roads area (more…)

If there were going to be a theme for this year’s ASLA Student Awards, it might well be sea change. A shift is palpable in the way students now seem ready to fully embody their roles as future leaders. There was great assurance in this group of award winners and a courageous willingness to tackle complex and difficult problems. The ambition of student projects leapt forward on multiple levels, with many submissions seeming to overrun the confines of traditional award categories. Projects as small as Chicago’s Jazz Fence, a Community Service winner, and as grand as the Award of Excellence winner in Analysis and Planning, El Retorno a la Tierra, which called for a total rethinking of the post-Hurricane Maria recovery of Puerto Rico, exemplified the deeply researched and carefully calibrated impacts of landscape architecture at its best. Projects ranged with authority across borders both political and cultural and did not shy from confronting the politics of place head-on. Jurors admired that “there are a lot of intense sites,” and projects were moving far away from conventional places that students had studied in the past.

And then there was the sea itself, a changing condition that appeared in many submissions, particularly in the Analysis and Planning category. With water and aridity in all its forms at the center of so many projects, it was clear that accommodating sea-level rise and climate change is no longer a choice to make but a condition that is baked into students’ design thinking. Submissions also exemplified full engagement with social issues once seen as far outside the profession’s purview, such as prison yards, nuclear plants, and a landscape approach to the reunification of Korea, which garnered an Award of Excellence in Communications. During the lively deliberations, jurors commented more than once about the remarkable initiative of this year’s students, particularly the “complexity and depth of issues they chose to tackle,” as well as how much they looked forward to hiring this next generation of landscape architects.

A spoiler alert: Among the ASLA Professional Awards, Brooklyn Bridge Park brings home the top honor in General Design, the Award of Excellence. Having taken shape over nearly three decades, the vast waterfront park, by Michael Van Valkenburgh Associates, came almost fully into being this year, a dogged vision for turning an old world into another one. And look at the results. This winner and many others show the long game of landscape architecture.

The Union of Concerned Scientists’ recent report on the economic damage and displacement that sea-level rise flooding will unleash called for investments “in a range of coastal adaptive measures,” such as “the protection of wetlands, and barrier islands, and other natural flood risk reduction methods” and other “natural infrastructure.” That puts the onus of surviving sea-level rise very clearly on landscape architects.

The report, Underwater: Rising Seas, Chronic Floods, and the Implications for US Coastal Real Estate, which the Union of Concerned Scientists (UCS) compiled with help from the real estate website Zillow, shows the consequences of sea-level rise in the short and long term, down to the state, city, and zip code levels of granularity. Released in June, it estimates lost houses, lost home value, lost tax base, and lost population by the years 2035 and 2100. (more…)

In Miami Beach, elevating streets is not without growing pains.

FROM THE AUGUST 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Faced with rising sea levels, the City of Miami Beach is lifting itself out of the water’s way—one street at a time. Beginning with the neighborhoods lowest in elevation, the city has raised dozens of streets in the past few years, some by as much as two feet. The $500 million project, which also includes new stormwater pumps, is a coordinated effort to prevent flooding in the long term. In the short term, however, the rapid elevation of the public right-of-way is presenting the city with novel challenges.

Some of those challenges, such as pumps that can fail during power outages, are mechanical. Others are legal. When one restaurant flooded, its insurance company initially refused to cover damages after classifying the restaurant’s dining area as a “basement” since it was now lower than the surrounding grade. (The city installed generators to solve the first problem and advocated on behalf of the restaurant owner, whose claim was eventually approved, to solve the second.) Other challenges involve the design of the public realm. (more…)

FROM THE JULY 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

On a chilly Sunday afternoon in the spring of 2016, a group of designers and preservation professionals wandered through one of Newport, Rhode Island’s oldest neighborhoods, visualizing what it would look like underwater. It wasn’t hard to imagine water flowing down the narrow streets and into the basements of the quaint, colonial-era homes located just blocks from Newport Harbor and a mere four feet above sea level. Some had already seen it.

In 2012, Hurricane Sandy sent floodwaters into many of the Point neighborhood’s historic homes, including 74 Bridge Street, a red-painted, two-story house originally built in the late 1720s. The basement flooded up to the first-floor framing and the kitchen took on at least seven inches of water.

Two years later, the Newport Restoration Foundation (NRF), a nonprofit preservation group founded by Doris Duke in the 1960s, purchased the house at 74 Bridge Street. As the house of one of Newport’s most notable cabinetmakers, a Quaker named Christopher Townsend, it had sat for years at the top of the NRF’s list of most desirable historic Newport properties. It was an important acquisition for the NRF, which currently owns 78 properties throughout the city and helps fund their upkeep. But the organization also knew that 74 Bridge Street would flood again.

“It’s in the lowest point in the Point neighborhood—literally, the lowest topographical point,” says Shantia Anderheggen, NRF’s former director of preservation. With sea levels on the rise—and in Newport they already had risen 11 inches over the past century—it was a statistical certainty that what happened in 2012 would happen again. And it wasn’t just the Townsend residence. The entire Point neighborhood, which has one of the highest concentrations of colonial-era structures on the continent, was under siege from the sea.

The McHarg Center—a new research initiative that will study the intersection of urbanism and ecology—is dedicated to studying how “urban growth and all of its related infrastructure can relate better and be better tuned to ecosystems,” says Richard Weller, ASLA, chair of the landscape architecture department at the University of Pennsylvania. The center is awaiting its formal launch next year with an exhibition, book, and conference timed to the 50th anniversary of Ian McHarg’s seminal book Design with Nature. In the meantime, the center, housed within PennDesign, has invited Jeff Goodell, the author of The Water Will Come: Rising Seas, Sinking Cities, and the Remaking of the Civilized World (Little, Brown, and Company, 2017), to visit for an inaugural lecture on March 29, at 6:00 p.m. in the lower gallery of Meyerson Hall.

In the spirit of McHarg’s research, Weller envisions the McHarg Center as an intensely multidisciplinary place. “When he completely overhauled the curriculum at Penn, he stacked the building with scientists,” Weller says. Likewise, Penn’s McHarg Center will invite scientists, designers, engineers, and public policy experts into an (more…)
