You can reach her at sduempelmann@gsd.harvard.edu. “ The account of Ruth Shellhorn’s life and work is important for us today because women’s work and contributions in the field are still underrepresented, neglected, overlooked, and undervalued.” GWENETH LEIGH, ASLA, (“Peter Walker’s Point,” page 78) is a landscape architect and freelance writer based in Canberra, Australia.

walled cities

In the Cleveland Park neighborhood of Washington, D.C., many residents really dislike the idea of having new short-term housing for homeless people nearby. The residents of this zip code, 20016, are 85 percent white, overwhelmingly registered as Democrats, and have a median household income of $122,087. Earlier this year, D.C. Mayor Muriel Bowser proposed seven sites around the city for new shelters, putting them in all but one of eight wards to avoid concentrating homeless residents in any one ward. These shelters would replace the city’s dreadful and dangerous shelter now operating at the old D.C. General Hospital, where as many as 270 families live in a place you might call humane only because it has a roof. There has been local opposition to the mayor’s plan in every ward,…

keeping up jones

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 1999, a tornado warning sent residents of Dubuque, Iowa, seeking shelter belowground, only to find their basements flooding. “It was evacuate the tornado shelter or drown,” one resident reportedly told the local newspaper. Since then, Dubuque, a scenic midwestern city perched on the Iowa banks of the Mississippi River, has seen five more floods severe enough to warrant presidential disaster declarations. “It got to a point where people who lived here said, ‘That’s enough,’” says Jon Dienst, a civil engineer who works for the city. The intermittent devastation of the past 17 years has driven Dubuque to adopt a progressive stormwater strategy. It is retrofitting its floodprone alleys downtown, converting impervious asphalt to red brick-like porous paving. Whereas many cities have just a handful of completed green alleys, Dubuque, a…

river reroute

As nearly 200 dams near the end of their functional life spans in California, one of the big questions is what to do with the sediment that has built up behind them. Until 2015, the 94-year-old San Clemente Dam on the Carmel River was a case in point, having almost completely silted in with 2.5 million cubic yards of sediment. As plans to remove the dam were made, regulatory agencies sought to prevent the sediment from being released into the river, even over time, but trucking it offsite would have been prohibitively expensive and have its own environmental consequences. A serendipitous solution came in the form of an adjacent tributary, San Clemente Creek. Officials came up with a design that rerouted the river into the creek and used the original river…

“Trees are a strategy in the whole green infrastructure tool kit,” Greg McPherson says in his bright tenor over the phone, “but the science that underpins that is really in its infancy.” McPherson, a research forester with the U.S. Forest Service, is speaking from an outpost of the Pacific Southwest Research Station in Davis, California. He says although experts have known that surface storage—the amount of water temporarily stored on a tree’s leaves and branches—is dictated by a tree’s architecture and the physical characteristics of its leaves and stems, green infrastructure accounting tools often assume a surface water storage capacity of one millimeter, regardless of species. Using a rainfall simulator to test 20 tree species commonly found in Davis, McPherson and the water research scientist Qingfu Xiao found that some species…
