Back in the 1970s, the architect Jaime Lerner initiated in the Brazilian city of Curitiba a form of urbanism that is still with us today. Bogotá, for example, owes much of its current success (which basically comes down to a rejection of car modernization) to Lerner and the policies he pushed and implemented while mayor of Curitiba. For him, public transportation, parks, cultural richness, and walkability (the streets) are what make a city a city. After his talk tonight, I will host a discussion about his talk as part of Town Hall’s Civic Roundtable Series. (Town Hall, 1119 Eighth Ave,, 7:30 pm, $5)
