Just read a bit on it and it’s not farmland. However, the story is pretty grim where they tried to build the park elsewhere but rich families pushed back. Then, among the lot they finally chose, there was communities of slaves and european immigrants. They used racism to make their eviction look better referring to them as insects among other things. Landlords (20% of the pop) got compensation but squatters and renters did not.

Plenty of other better examples of thriving black communities being destroyed by eminent domain by the US however. https://historyfortomorrow.org/story/eminent-domain-and-the-displacement-of-black-communities/
