Yeah no. Actually the beach didn't exist before Moses, it was a marshy island. He literally created it in the 20's. Read the history section here: https://en.wikipedia.org/wiki/Jones_Beach_State_Park

Public accessible beaches and parks for hemmed in city dwellers back then in the era of tenements and no air conditioning were not at all common, creating something like Jones Beach was a major public good.

The story of Moses's contributions is generally one of incredible progress and public good in the first era of his career, followed by an increasing descent into arrogance and lust for power that was ultimately highly destructive in many cases.

It's an interesting and nuanced story. Were you to know the first thing about it you'd likely agree.
