As Ken Buettner explains in the podcast, “A sidewalk shed is really a New York Cityinvention(発明).The building code (建築基準法)created sidewalk sheds probably 80 or 90 years ago.
The sidewalk shed used to be [made of] heavy timbers. People who are old enough or if you have photographs going back, you might see sidewalk sheds being used on demolition sites (解体現場)going back 70, 80 100 years where they were big 12×12 wooden timbers that were vertical(縦の), ahorizontal (横の)structure also using timbers and then the parapetwall (胸壁)around the top of the shed on those ancient (昔の)sites would often have been the wooden doors that were taken from inside the buildings to be demolished. Nothing was left to waste, and it met the code and it sufficed(十分足りている).”
As Mark Levine explains, that’s all in the zoning code(規制), which specifies(特定する)the exact shade of green and the minimum height (eight feet tall). “Another big piece of our policy agenda,” he explains, “is that if you’re gonna put scaffolding, or a sidewalk shed in place, allow it to be less ugly.” Urban Umbrella is one alternative, created during the Bloomberg administration, but only one company is currently allowed to install it. Levine explains that other cities are doing things like cantilevering (片側だけが固定されている)scaffolding, using more netting, and allowing for alternative colors or art, “We’re also trying to rethink what these things look like on the street,” he explains.
