An analysis by NPR based on modeling from the National Hurricane Center for New York City, Washington, D.C., and Miami-Dade County found future sea rise could expose about 720,000 more people to damaging floods later this century.
The analysis used three hurricanes—Sandy, Isabel, and Irma—as benchmarks to understand future storm surge impacts. By 2080, when sea rise could surpass three feet, flooding would engulf more critical infrastructure, including hospitals and schools that often provide emergency shelter.
While rising waters are destructive, powerful hurricanes add another element. High winds amplify storm surges and push walls of water onto shore. This repetitive shock loading causes extensive structural failure.
In the Miami area, flooding already at lethal levels under current conditions would top nine feet farther and move farther inland as waters rise. The number of people at risk could nearly double by 2080, based on NOAA’s likely sea level rise projection of just over 2.5 feet, according to the analysis.

Mixed-Use on Steroids
Mixed-use development has been one of the few bright spots in real estate in the last few years. Successful mixed-use projects are almost always located in dense urban or suburban areas, usually close to public transportation. It’s a sign of the times that the residential component tends to be rental rather than for-sale.

Product of the Week: Zinc cladding helps border crossing blend in with surroundings
Zinc panels provide natural-looking, durable cladding for an administrative building and toll canopies at the newly expanded Queenstown Plaza U.S.-Canada border crossing at the Niagara Gorge. Toronto’s Moriyama & Teshima Architects chose the zinc alloy panels for their ability to blend with the structures’ scenic surroundings, as well as for their low maintenance and sustainable qualities. The structures incorporate 14,000 sf of Rheinzink’s branded Angled Standing Seam and Reveal Panels in graphite gray.

New Years resolutions for architects, urban planners, and real estate developers
Roger K. Lewis, an architect and a professor emeritus of architecture at the University of Maryland, writes in the Washington Post about New Years resolutions he proposes for anyone involved in influencing buildings and cities. Among his proposals: recycle and reuse aging or obsolete buildings instead of demolishing them; amend or eliminate out-of-date, obstructive, and overly complex zoning ordinances; and make all city and suburban streets safe for cyclists and pedestrians.
