In 1930, Port Washington tried to incorporate itself as a city, which would have had the same boundaries as the Port Washington Union Free School District – excluding Sands Point, which had already incorporated itself as a village several years prior.[6] This plan ultimately failed when the bill was killed after Baxter Estates, Flower Hill, and Manorhaven incorporated themselves as villages in order to retain home rule over their respective areas.[6]
