Every single big, forgotten, rust-belt city underwent similar growth periods and somehow figured it out. This isn't an unprecedented or technically difficult problem to solve. Take a look a Detroit's population boom at the beginning of the last century: - 1900 285,704 - 1910 465,766 - 1920 993,678 - 1930 1,568,662 And you think 21st-century Seattle can't absorb 142,252 people? How did Detroit do it? They built vast tracts of densely-situated multi-story apartment buildings. Did that change the character of those neighborhoods? Obviously. So what? There is no mystery here.
