FROM THE NOVEMBER 2019 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

Named for the walnut trees that used to line its banks, the Arroyo de los Nogales, a tributary of the Santa Cruz River, flows from south to north, descending from the high Sonoran desert in Mexico into Arizona. The main arroyo and its many smaller tributaries form a watershed, shaped roughly like a human heart, that is broken in two by the U.S.–Mexico border wall. Facing each other across the wall, in the river’s floodplain, are two cities, each named Nogales, that share social and environmental problems—including repeated flooding caused by rapid urbanization, ineffective flood control efforts, and the border wall itself.

Gabriel Díaz Montemayor, ASLA, an assistant professor of landscape architecture at the Fay Jones School of Architecture and Design at the University of Arkansas, and Francisco Lara-Valencia, an associate professor at the School of Transborder Studies at Arizona State University, have a greener vision for these border cities (together called Ambos Nogales), whose streets and arroyos often run brown with sediment and sewage in heavy storms. Díaz Montemayor and Lara-Valencia want to increase permeability throughout the watershed, slow peak flows in heavy storms, and develop more ecological connectivity between the two cities, despite the dividing presence of the wall.

They hope their ideas for an extensive network of green infrastructure can transform the way the cities develop, not only to improve water quality and flood management but also to provide more green space for residents. As the cities have grown, impervious surfaces have too, destroying natural areas. Both cities lack green space: There is just 1.1 square meter per person in Nogales, Mexico, and only 2.2 square meters per person on the U.S. side, Lara-Valencia says.

“We are not saying development shouldn’t happen,” Díaz Montemayor says. “We’re saying, ‘Let’s provide a structure for that development to happen [that] is based on natural systems.’” (more…)

FOREGROUND

Get with the Program (Tech)
As workflow patterns change, designers are diversifying in the types of software they rely on,
a recent survey of landscape architects shows.

Lunch Break Brutalism (Preservation)
The water is flowing again at M. Paul Friedberg’s much-disputed Peavey Plaza in Minneapolis,
after a renovation by Coen+Partners adjusts the space to latter-day concerns.

FEATURES

Look to the Sky
In Santa Fe, Surroundings Studio relies on scarce rainfall for all the water one
house’s garden could need.

Floods That Know No Bounds
Nogales, Mexico, and Nogales, Arizona, have a border wall between them, but an unruly, overstressed watershed needs a binational solution to stop flooding. Gabriel Díaz Montemayor, ASLA, and a colleague, Francisco Lara-Valencia, have some ideas.

Get Real
Vicki Estrada, FASLA, talks about the change in her practice at Estrada Land Planning in San Diego
since her transition 13 years ago. For one thing, it has meant no more going along to get along

In Kīlauea’s Wake
After a series of violent eruptions of Kīlauea in 2018, the staff of Hawai‘i Volcanoes National Park is figuring out ways to proceed with a natural and cultural treasure that is constantly changing.

After two rare storms inundate Ellicott City, Maryland, the town tries to sort through what can be saved.

This week, LAM is joining more than 250 media outlets for Covering Climate Now, flooding the zone, as it were, with climate coverage in the run-up to the United Nations Climate Action Summit on September 23. Landscape and landscape architecture are deeply implicated in the future of climate progress, or a lack of it. Over the past decade, LAM has dug into climate issues of landscape in numerous dimensions, mapping the big resource picture as well as local attempts to fend off increasingly apparent hazards of global warming—from the procurement of materials to the integrity of the food supply chain. Each day this week we’ll bring you excellent stories from recent years that follow landscape architects acting and thinking about climate change and the landscape.

The Tiber-Hudson watershed, in Howard County, Maryland, drains three-and-a-half square miles of mostly developed land in and around Ellicott City, a historic mill town founded in 1772 on the banks of the Patapsco River. The terrain surrounding the town is steep. On the south side of lower Main Street, a series of mill buildings is packed alongside and astride the Tiber Branch, one of the watershed’s three main tributaries to the Patapsco. On the north side, old stone buildings are backed up to a hill made of granite bedrock. Rainwater flows downhill, east toward the river, and in Ellicott City, there’s nothing farther downhill than lower Main Street, the historic center of the town.

When I visited at the beginning of February, the sun was out and it was warm enough to leave my jacket in the car. Walking downhill into lower Main, where the street is narrower, the air temperature dropped and the shadows darkened. On my right, behind a row of boarded-up storefronts, I could hear the Tiber Branch rushing along parallel to Main Street. It smelled like a basement.

On the night of July 30, 2016, a storm rolled in and sat directly on top of Ellicott City, dropping 6.5 inches of rain in the watershed in just three hours. Water jumped the banks of the Hudson Branch uphill and flowed down Main Street, (more…)

THE RISING TIDEWATER

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.

This week, LAM is joining more than 250 media outlets for Covering Climate Now, flooding the zone, as it were, with climate coverage in the run-up to the United Nations Climate Action Summit on September 23.

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…)

Why a Maryland landscape architect restores brook trout habitat in his free time.

FROM THE AUGUST 2019 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

The underbelly of an eastern brook trout, especially when it is spawning, is orange and pink like a sunrise, and its back is dappled brown and green like a forest floor. The spots along its lateral line are small and circular like pink and yellow confetti, and the vermiculations on its back are yellowish and serpentine, like a Polynesian tattoo. It is a small fish, typically no longer than about 10 and a half inches—the height of this page—fully grown. It breeds in streams as far west as Minnesota and as far south as the extent of the Appalachian Mountains, in Georgia. First described in 1814, the species is thought to have come into its own during the Pliocene Epoch, between two million and five million years ago. Unlike the brown trout, which is commonly stocked for sportfishing, the brook trout is a member of the char genus. Both are members of the Salmonidae family, which also includes salmon.

The brook trout insists on cold water, and prefers to spend time in waterways with an even distribution of riffles and pools. When it is feeding, on plankton at first and later on insects as it matures, the fish wants to spend as little energy as possible to acquire food. It will hide in shadow in deep pools, and wait for bugs to come surfing down the thin seam of fast water that flows downstream from shallow rapids. If it senses an opportunity, it will strike. Sometimes it will catch a mayfly nymph, and sometimes it will catch an artificial fly tied to a fishing line owned by Scott Scarfone, ASLA. (more…)

FROM THE NOVEMBER 2018 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

For a long time, the Anacostia River didn’t even have a name. It was just the Eastern Branch, the other, less promising section of Washington, D.C.’s better known and more distinguished river, the Potomac. But it was always known as a fortunate course to the Nacotchtank, the Native Americans who used it as a trading post, and later to the European colonists who relied on the river’s deep port at Bladensburg, Maryland, to carry tobacco, and to the generations of farmers, tradesmen, and laborers who never seemed to run out of fish, fowl, and game to hunt. For nearly nine miles, the Anacostia eased in and out with the tide, with no particular urgency, toward its confluence with the Potomac, tracing an unhurried flow through thousands of acres of tidal wetlands.

Of course, that was before the port and the shipping channels silted up in the 19th century from agricultural misuse; before the river was (more…)
