Not since the crazed building boom that followed the 1905 Lewis & Clark Centennial Exposition has Portland grown so quickly as during the last decade. Construction cranes have reshaped neighborhoods. Cars, bikes, buses, and scooters clog the streets.

Wealthier people have moved in while poorer people have been pushed further out, sometimes to the street. And Portlanders new and old want some simple questions answered: What’s the city’s plan? Who’s benefiting? Why are so many losing? What kind of Portland are we making? We invited 38 city leaders, activists, and architects to offer their visions for Portland’s future.
