Within the built environment, which is too. PACIFIC CITY, Ore The collapse of a sandstone arch at Cape Kiwanda is a reminder of the potential dangers of the fragile landscape. Since the 19th century, the planet has warmed by 2° Fahrenheit. “It’s important to show that people have been doing these projects, and they’ve turned out to be a safer route. 2020 was tied with 2016 as the hottest year on record. “A lot of communities are still concerned with the idea of partnering with nature, because many of these ideas are still novel,” says Green.
Where many cities turn to infrastructure, landscape can often do a better job. The guide recommends these types of nature-centric initiatives over building walls or raising homes up on stilts, which are expensive, disruptive to nature, and not guaranteed to work. The pond replaced an earlier initiative for a $40 million underground tunnel to remove rain water. Based on photos shared with KGW, the collapse. Green also points toward the Historic Fourth Ward Park in Atlanta that was recently designed so that flood water from the surrounding neighborhood would flow into its five-acre pond. The collapse of a sandstone arch at Cape Kiwanda is a reminder of the potential dangers of the fragile landscape. But until that happens, designing in roadside trees and green spaces can mitigate some of that runoff. Green spoke to Louisiana-based landscape architect Wes Michaels about the flooding for an ASLA blog post, and he brought up the need to redesign roadways so they’re porous to the flow of water–asphalt essentially acts as a conveyor system for water, moving it around but not absorbing it. But these forms of vegetation don’t just provide their own cooled-down microclimates–they also have the potential to actually decrease a city’s temperatures if done in a comprehensive, systematic way. DL stands for 'Dangerous Landscape' Landscape replaced dangerous nature.
Yet, as Green describes, “When you walk off the hot streets of New York in the summer and into Central Park, there’s a noticeable temperature difference.” It’s an example of one of the guide’s core tenets–that trees, parks, green roofs, and other green spaces create natural cooling by providing shade and releasing moisture. “We can now use multilayered systems of protection, with diverse, scalable elements, any one of which can fail safely in the event of a catastrophe.” The effects of this temperature rise is exacerbated in cities, where pavement absorbs and traps heat. Heatwaves Are Dangerous, But Green Space Can HelpĪccording to NASA and the National Oceanic and Atmospheric Administration, 2015 was the warmest year on record, continuing a long-term trend of global warming that has seen earth’s temperature rise 1.8 degrees Fahrenheit since the late 19th century.
