Cesspool Installation Hillside Manor

The name Hillside Manor was chosen as the name of the hamlet by residents in 1946 when proposing names for a new post office to be located within the hamlet.

On December 1, 1948, the Hillside Manor Post Office opened, functioning as a branch of the New Hyde Park Post Office. At the time, there were approximately 9,000 people residing in Hillside Manor. When the post office was first unveiled in November 1948, the stone nameplate on the building erroneously said “Garden City Park” due to an error on the blueprints, causing a massive uproar from local residents as well as from the press; the engraving on the nameplate was soon corrected to display the name “Hillside Manor.”
