The Environment Impact Statement said it was ok to get rid of the mountain and to fill the bay.

Moment at 0:58 in Seattle Cut Down an Entire Mountain #shorts by Asad Shafique.

Over a hundred years ago, Seattle did something almost no city has ever attempted — it erased an entire mountain from the middle of downtown. Denny Hill rose over 100 feet exactly where the city needed to grow, so engineer Reginald Thomson decided to wash it into the sea using high-pressure water cannons. From 1898 to around 1930, the city sluiced the hill away block by block. This is the incredible true story of how they did it, the famous "spite mounds" left behind, where all that dirt actually went, and what the site looks like today. History and engineering like you've never seen it.
