There’s a lot to love about bamboo.

FROM THE NOVEMBER 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

Thousands of lucky San Franciscans will soon be walking through a bamboo forest on their way to and from towering glass buildings in the city’s Mission District. Groves of giant Japanese timber bamboo (Phyllostachys bambusoides) are a stunning horticultural statement in a 5.4-acre park atop the new Transbay Transit Center, scheduled for completion later this year. It’s just one more sign of bamboo’s increasing popularity, despite its bad reputation.

The park, long and skinny, is 70 feet aboveground and extends four blocks, with public access by bridges that connect with adjacent skyscrapers, by gondola from street level, or by escalator, elevators, and stairways inside and outside the building. Adam Greenspan, ASLA, a partner at PWP Landscape Architecture, explains that no matter what level people are on, “we wanted them to see that there was an inhabitable landscape up on the roof.”

The dominant feature of the Transit Center is a light tower that extends from the grand concourse at street level up to the roof, where its glass dome is surrounded by bamboo. Greenspan says he selected Japanese timber bamboo because it allows for “transparency and translucency,” and when you’re inside the building, “you get a bit of filtered light through foliage and through stems and culms.” Up on the roof is a “transparent scrim of green.” The bamboo is planted in a concrete basin about four feet deep, which sequesters the bamboo’s rhizomes so they (more…)

The compensatory mitigation mandate opens a dynamic arena for landscape architects.

From the August 2015 issue of Landscape Architecture Magazine.

 

“Konk-la-ree!”

Or,

“O-ka-lee!”

The song of the red-winged blackbird, although instantly recognizable, is hard to put to words, as even Roger Tory Peterson, author of A Field Guide to the Birds, found. These syllables are his best efforts. The trilling, almost metallic-sounding warble evokes summertime, cattails, and the watery landscapes where Agelaius phoeniceus goes to breed.

But at this moment I’m not seeing cattails. I’m at the edge of a parking lot behind a pizza restaurant in a suburb north of Boston, looking at a large pit, about 10 feet deep, filled with Phragmites australis, the infamous invasive species that, along with purple loosestrife (Lythrum salicaria), is the scourge of wetlands in the Northeast, choking out cattails and other native species that provide food to the bird population. A few spindly red maples have colonized the embankment, along with some riverbank grape (Vitis riparia), Virginia creeper (Parthenocissus quinquefolia), and Rosa multiflora, a pretty though sprawling shrub introduced to America in 1866 to provide rootstock for hybrid roses and now classed as a pest in many states. Despite the red-winged blackbird’s bright song, this is a dismal place, especially in the fading afternoon sunlight, a bit of wasteland left behind by development, one of millions of similar places across the country.

This blighted spot, however, is a mandated compensatory wetland mitigation under (more…)
