On a hot, dry day in Los Angeles, pedestrians could feel 7 degrees warmer on a reflective road than on a normal blacktop, researchers find.
Sam BlochL.A.'s trying to cool down by covering streets in reflective coating. But that heat doesn't disappear—it gets soaked up by pedestrians. My story on important new urban heat research for @CityLab
The nation’s largest sidewalk repair effort gets underway.
Sam BlochSo yes, plant more trees. But to do it equitably, reengineer the sidewalks first. L.A. actually has an amazing opportunity to do this right now, through an ADA-related settlement to repair 4,400 miles of broken sidewalks—ironically, due to ficus trees.
Examines the evolution of an undervalued urban space and how conflicts over competing uses—from the right to sit to the right to parade—have been negotiated.
Urban sidewalks, critical but undervalued public spaces, have been sites...
Sam BlochIt’s hard to plant big street trees in poor neighborhoods, which have lots of overhead powerlines and narrow sidewalks. In Sidewalks, a study shows that household income is the only statistically significant variable in determining tree canopy. 15/
It’s a civic resource, an index of inequality, and a requirement for public health. Shade should be a mandate for urban designers.
Sam BlochA thread! @PlacesJournal published an article I wrote about the politics of shade in Los Angeles. Shade, as in, what’s under a tree, or a covered walkway, or created by an awning—basically, where you want to be on a hot day. It’s cooler there! 1/
