Port Washington, LI — Manhasset Bay, a Direct Train to Penn Station, and a Genuinely Strange Tax System

What Actually Makes Port Washington Different

Port Washington is a hamlet on the Cow Neck Peninsula -- also called Manhasset Neck -- a spit of land in the Town of North Hempstead, Nassau County, bounded by Manhasset Bay on the west and Hempstead Harbor on the east, both opening north into Long Island Sound. English settlement here dates to 1643-1644, when 18 families rowed across the Sound from the Stamford, Connecticut area, bought land from the Matinecock people, and fenced the peninsula off as cattle-grazing land -- which is where the older name 'Cow Neck' comes from; the first permanent resident is recorded as arriving in 1674. The peninsula today contains four incorporated villages with their own local governments -- Baxter Estates (incorporated 1931), Manorhaven, Port Washington North, and Sands Point -- plus part of the separately incorporated Village of Flower Hill, while the commercial hamlet center along Main Street is unincorporated and run directly by the Town of North Hempstead. That layered structure -- one hamlet identity, five separate village governments (four full, one partial) sharing the peninsula -- is a real, distinctive administrative fact a buyer needs to understand before assuming a single set of local rules applies everywhere on the peninsula.

Manhasset Bay itself is a deep, well-protected natural harbor, and it has driven the local economy through two genuinely distinct eras. From roughly 1865 to 1989, Port Washington was one of the busiest sand-and-gravel export ports on the East Coast: more than 200 million tons of sand were shipped from the Cow Neck sand banks to New York City to make concrete, and by some published calculations as much as 90% of the concrete that built New York's sidewalks, subway tunnels, building foundations, and skyscrapers came from here. Colonial Sand & Gravel, the largest operator, is credited with supplying concrete for projects including Rockefeller Center and Radio City Music Hall. More than 800 immigrant laborers -- from Italy, Poland, Ireland, Germany, and Scandinavia -- lived in barracks on the sand banks and did dangerous work; cave-ins were a real, recurring hazard. Roanoke Sand & Gravel, the last operator, ceased mining in 1989, and the Cow Neck Peninsula Historical Society maintains a sand-mining monument marking that history today. The second era arrived in 1939: Manhasset Bay's depth and Long Island Sound's open approach made Port Washington the launch point for Pan American Airways' Boeing 314 flying boat Yankee Clipper, which departed Port Washington on May 20, 1939 on the first scheduled transatlantic airmail flight, and flew the first scheduled transatlantic passenger flight on the northern route on July 8, 1939 -- a real, well-documented aviation-history fact tied directly to this specific harbor, not a general Long Island claim.

Sands Point, the incorporated village occupying the peninsula's northern tip, sits within Long Island's well-documented Gold Coast -- the early-20th-century estate district built by industrial and finance fortunes. F. Scott Fitzgerald lived in nearby Great Neck (across Manhasset Bay) from 1922 to 1924 while writing The Great Gatsby, and Sands Point is widely and consistently cited by literary scholars and journalists as the real-world inspiration for the novel's East Egg, with Great Neck itself standing in for the nouveau-riche West Egg. What is precisely confirmed: Fitzgerald lived across the bay from these estates during the exact period he wrote the book, and the Gold Coast's concentration of grand waterfront mansions is real, well-documented, and largely still standing. What is not confirmed, and this page won't claim as settled fact: whether Fitzgerald ever set foot inside any specific Sands Point mansion, or which single house (if any) was 'the' model for Gatsby's own. The most substantial surviving piece of that era open to the public is Sands Point Preserve, a 216-acre former Guggenheim estate with four Gold Coast-era structures -- Hempstead House, Castle Gould, Falaise, and the grounds themselves -- covered in more depth on this site's Things to Do and What Nobody Tells You pages.

Port Washington's other defining, everyday-practical fact is transportation: the LIRR Port Washington Branch is the only branch of the Long Island Rail Road that runs directly into Manhattan without transferring at Jamaica. Wealthy residents lobbied to have the railroad terminate here back in 1895, which required building the Manhasset Viaduct, and travel times improved sharply once the East River Tunnels opened in 1910, cutting the ride to under an hour. Multiple current schedule sources put the trip at roughly 35 to 40 minutes to Penn Station today -- genuinely similar to travel times reported when the tunnels first opened, a real historical throughline for a commuter town this close to New York City.

Property tax in Nassau County runs on a system this page treats carefully rather than glossing over, because it is genuinely different from most of the country and has been the subject of real, ongoing controversy and litigation. For years, Nassau valued residential property using 1938 construction costs less depreciation, plus land value as of 1964 -- an assessment method so disconnected from current reality that it drove a wave of tax certiorari lawsuits, contributing to roughly $100-150 million in certiorari judgments against the County over time. The County's assessment roll was frozen entirely in 2011 by the prior administration; County Executive Laura Curran ordered a full countywide reassessment starting in 2018, and the County Legislature passed the Reassessment Phase-In Act (also called the Taxpayer Protection Plan) on March 23, 2020, phasing in any resulting market-value increase at 20% per year over five years starting with the 2020-21 tax roll. Nassau's Class 1 (one-to-three-family residential) properties have used a Level of Assessment fixed at 10% of determined market value since that 2020-21 cycle -- meaning a home's stated 'assessed value' on a tax notice is intentionally a small fraction of its actual market value, which can confuse a buyer comparing Nassau paperwork to a more conventional county's tax records. As recently as October 2025, a New York appellate court revived a group of Nassau homeowners' constitutional challenge to the assessment system itself -- this is not settled, historical controversy; it is active as of this research pass.

Several things this research could not pin down with the confidence this page requires to state as settled fact: a current, Port Washington-specific windstorm or flood insurance premium; the exact combined town-county-school property tax rate for a specific address (Nassau's layered rate structure and 10% Level of Assessment make a single clean 'rate per $100' harder to state simply than in a flat-assessment state, and this page does not want to guess); a current admission fee for Sands Point Preserve; and Port-Washington-specific Hurricane Sandy damage figures distinct from Nassau County or Long Island totals. Anyone seriously evaluating a purchase or move here should confirm current numbers directly with the Nassau County Department of Assessment, the Town of North Hempstead, a licensed NY insurance broker, and a local buyer's agent rather than assuming a figure found online is current.
