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…)

A sophisticated stormwater system elevates Philadelphia’s Girard Avenue interchange.

FROM THE NOVEMBER 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Around the world, cities are demolishing, burying, or capping their elevated freeways, but an interstate in Philadelphia provides a possible alternative—one in which the highway stays up but connectivity, open space, and water quality are still prized. In redesigning three miles of Interstate 95 north of Center City Philadelphia, the Pennsylvania Department of Transportation planned 27 acres of park and open space, and the first phase of the $1 billion project, due for completion by 2027, incorporates examples of green infrastructure. According to AECOM, the prime consultant on the project, landscape design and green infrastructure accounted for between 5 and 7 percent of the first phase’s total budget.

At the Girard Avenue Interchange, I-95 runs parallel to the Delaware River two blocks away. Rather than whisking stormwater runoff directly into the river, overtaxing an already burdened municipal system, or funneling a deluge into a rock pit, AECOM and other experts devised a treatment scheme of basins, weirs, bioswales, and rain gardens. Ten planted acres can capture the first inch of runoff (more…)
