John LaPlante, engineer who helped fix Chicago’s “Z-Curve,” dies from COVID-19


John LaPlante, a longtime city employee who served as the first commissioner of the Chicago Department of Transportation, died Saturday at 80 after testing positive for the novel coronavirus less than two weeks earlier. The son of a Cook County judge and the head librarian for the Chicago Public Schools, Mr. LaPlante was a “municipally minded” Roseland native who cared deeply about his city and its government, according to his daughter Leslie.



LaPlante worked for the City of Chicago for over 30 years, starting as an intern in the 1960s for what was then the city’s department of public works. He served as chief traffic engineer in the 1980s and as the city’s Transportation Commissioner in 1992. 

While working as the chief engineer, LaPlante helped to rework the infamous “Z curve” that plagued Lake Shore Drive for decades. Throughout his long career as a public servant, LaPlante worked to support and institute “Complete Streets” and other pedestrianization improvements in the built environment. 

After retiring from the public sector, LaPlante worked for transportation engineers T.Y. Lin International for many years, retiring in 2015.

Wood Urbanism: From the Molecular to the Territorial Daniel Ibañez, Jane Hutton, Kiel Moe (Editors) Actar Publishers , November 2019 Hardcover | 8 x 10-1/4 inches | 488 pages | English | ISBN: 978-1945150814 | $54.95 PUBLISHER'S DESCRIPTION : Wood holds unique and timely lessons for urbanization, yet it remains inadequately characterized in architecture, landscape architecture, and urbanism. From under-considered thermal properties to emerging manufacturing possibilities, from changing forestry regimes to larger carbon cycle dynamics, Wood Urbanism explores the unique material and scalar properties of wood, presenting it as a critical material for design today. It brings into conversation scholars and practitioners who focus on wood from a range of perspectives: from the working forest to the mid-rise building to the basic cell. Drawing from the inherent intelligence and depth of multiple disciplines, this book offers a transcalar perspective on the role of wood in cont...

Building a gentrification early warning system with big data

Resim
But what if there were a way to see gentrification long before the coffee shops, condos and Whole Foods appear? What if city planners and neighborhoods had an early warning system that could sniff out the changes just as they begin? [...] neighborhood advocates would have the opportunity to implement policies ranging from reserving affordable housing units to educating residents of their renting rights to helping small businesses negotiate long-term lease extensions. In his NPR piece, astrophysics professor Adam Frank explains how various big data sets, like housing prices, eviction records, census data, or social media usage, can be utilized for "predictive analytics" to detect early onsets of gentrification for specific neighborhoods at an increasingly high resolution — and what significant perils come with it.
