Central Park Conservancy (1980)
New York City created a private nonprofit, the Central Park Conservancy, to raise money and manage Central Park after years of decline. The group took over maintenance and restoration with private donations and city funds.
The conservancy restored major landscapes and became a model for public-private park management.
It showed private donors could reshape public parks, while raising questions about reliance on philanthropy.
Chesky's gift is a one-time capital pledge, not a permanent operating endowment like the conservancy model.
