Here is a link to the interview. Here is some text from the article on pedestrian safety and how important shade is to a cities walkability:
Speck’s prescription for achieving that includes adding parallel parking along the road to make walkers feel more protected than they do now. “When a car passes you on the sidewalk, you lack that barrier of steel that makes you feel safe and actually protects you from vehicles coming at you,” he said.
Speck also said plans call for creating “continuous deep shade” in the Florida heat. “Every building will likely have either an awning or arcade or something that shadows the sidewalk,” he said. Plans for the area involve adding retail and other destinations to the mix, but Speck said the biggest difference in the future may be “the number of people on the sidewalks.”
