A Barrier Island Seasonal Community

Ocean Beach sits on Fire Island, a barrier island off Long Island's south shore accessible only by ferry. With 79% of housing used seasonally (986 of 1,243 homes), the year-round population of 331 residents swells dramatically during summer months. This is a PO Box Only Zone. There's no street delivery across the entire island community.

Why PO Box Adoption Reaches 294%

The Ocean Beach post office maintains 530 PO Boxes for just 180 year-round households. That's 2.94 boxes per household, one of the highest adoption rates in New York State. The disparity isn't waste, it's necessity. Second homeowners maintain boxes year-round for off-season deliveries. Rental property managers need addresses for turnover management. Ferry-dependent businesses require mail access that doesn't rely on physical presence. Without cars on most of Fire Island, the post office becomes the central distribution point for an entire seasonal economy.

Island Streets Without Cars

The street network tells the island story. Instead of traditional roads, Ocean Beach uses pedestrian "walks" (Bay Walk, Cottage Walk, Evergreen Walk, Surfview Walk). Streets are named for coastal features (Ocean Rd, Surf Rd, Atlantic Walk, Kelp Ave, Shell Walk) and include whimsical touches like Pirates Walk and Mosquito Lane. The island character comes through in every address.

Demographics of Island Life

This isn't a working-class beach town. Median home values of $730,800 and a median age of 56.3 years indicate an established seasonal community. Only 50 single-family homes exist in the delivery data (spatial.sfdu), with 530 PO Boxes serving the community. Most properties are seasonal cottages and rental units passed down through families or maintained as investment properties.

Fire Island's Community Tapestry

Recognized community names beyond Ocean Beach include Seaview, Ocean Bay Park, Corneil Estates, and the overarching Fire Island designation (all marked as non-mailing aliases but culturally significant). These aren't separate municipalities. They're neighborhood identities within the broader Fire Island tapestry, each maintaining its own character while sharing the Ocean Beach post office.

The Ferry-Dependent Economy

Ferry dependency shapes everything. Year-round residents number only 331, but the post office infrastructure serves thousands during peak season. Transportation workers make up 53% of the employed workforce (DP03_0047E: 53), reflecting the marine-dependent economy. That's an extraordinarily high concentration, nearly triple the national average. Ferry operators, water taxi services, marina staff, and marine delivery workers form the backbone of island logistics.

Mailing to Fire Island

For mailing purposes, all addresses use Ocean Beach, NY 11770, even for properties in neighboring communities. The PO Box requirement isn't bureaucratic preference. It's geographic reality on a car-free barrier island where traditional carrier delivery would be impossible.
