 In what was dubbed a "Manhattanization wave", there were nearly 60 structures proposed, approved or under construction in the city that were planned to rise over in height.As a result of the construction boom, only two of the city's 25 tallest buildings were completed before the year 2000, and the city has one of largest skylines in the United States, generally ranking only behind New York City and Chicago.The boom, however, ended abruptly around 2008 when the real estate market crashed and the late-2000s recession began.
