Beavers become partners in restoration.

FROM THE JANUARY 2019 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

As public support for trapping has waned, beavers are making a comeback in urban waterways around the country. In Seattle, they are now said to be found in every suitable stream and water body, and some project designers now see them as partners in wetland restoration rather than nuisances. They say the benefits beavers bring to an ecosystem outweigh the challenges, and point out that working with them is far less expensive—and more humane—than trapping.

“Beavers construct wetlands that hold back and store water, allowing for groundwater recharge and pollution sequestration, and increasing biodiversity,” says Ben Dittbrenner, the aquatic ecologist and executive director of Beavers Northwest. “We do the same thing for hundreds of thousands of dollars, but they do it for free.” This past October, (more…)

We were driving around west Philadelphia when Anne Whiston Spirn, FASLA, stopped at the corner of Walnut and 43rd Streets to recall the moment of discovery that still drives her work. It was 1971. She was a graduate student at the University of Pennsylvania, on her way to the supermarket, when she was stopped at a gaping hole where the street had caved in over the Mill Creek sewer. “I looked down and saw this big, brown rushing river, and all this masonry that had fallen in. I thought, ‘My God, there are rivers underground. We’re walking on a river.’”

She was looking at Mill Creek, buried in the brick sewer pipe in the 1880s. Historic photographs show workers dwarfed by its size, constructing the pipe, about 20 feet in diameter, snaking along the creek bed. Drawings depict horse-drawn carts loaded with soil—millions of cubic yards dug with pickaxes and shovels—to cover up the pipe. Row houses were built right on top of the fill.

That buried river would become the heart of Spirn’s work when she came back to Penn 15 years later to chair the landscape architecture department and to launch the West Philadelphia Landscape Project (WPLP), but also in her larger vision of (more…)

A historic airfield in Massachusetts is transformed into a haven for biodiversity.

From the February 2016 issue of Landscape Architecture Magazine.

“Are you folks from the parks department?” asked a white-haired man in hiking clothes.

It was an early summer morning, and he approached a small group standing in a path at 1st Lt. Arthur E. Farnham Jr. and SSgt. Thomas M. Connolly Jr. Memorial Park, which covers 12 acres on the 338-acre site of a former regional airport in Canton, southwest of Boston. The group did not include anyone from the park’s managing agency, the Massachusetts Department of Conservation and Recreation (DCR). But it did include the park’s designers, Deneen Crosby, ASLA, and Daniel Norman, ASLA, from the Boston firm Crosby | Schlessinger | Smallridge (CSS). With them was the consulting biologist Ingeborg Hegemann, the senior vice president of ecological sciences and principal at BSC Group, a Boston-based environmental services firm. Hegemann worked with CSS to evaluate the soils, review proposed grading, and select plants and seed stock for the park, which includes extensive restored wetlands.

The park visitor, a retired Canton resident who identified himself as “Mike,” described a woman he had spotted digging up plants and stashing them in her trunk. “She had a shovel in the car, so it wasn’t the first time,” he said, pulling a notebook from his day pack. He read out a plate number. Norman jotted it down. “I come here almost every day,” said Mike. “I love this park, and I don’t want to see it destroyed.”

It was the kind of gratifying feedback professionals who work on public projects rarely get firsthand, and it left the team (more…)
