Key Facts
  • 65% of housing units (54 of 83) are seasonal vacation properties, one of the highest rates in New York State
  • The post office maintains 65 PO Boxes for just 12 year-round households, reflecting extensive second-home ownership
  • Only one street (County Route 6) receives traditional mail delivery in the entire ZIP code
  • The ZIP code has a MultiPoint geometry rather than a polygon boundary, indicating island or disconnected land masses
  • With 45 residents spread across island properties, the population density makes boat-based delivery impractical
  • The median age of 48.5 years suggests retirees and empty-nesters as the primary property owners

Seasonal Occupancy Drives the Postal System

Chippewa Bay sits in the Thousand Islands region of the Saint Lawrence River, where seasonal occupancy defines the postal landscape. Of 83 total housing units, 54 are seasonal or vacation properties. That's 65% of all housing, creating a community that swells in summer and quiets in winter.

Why Second-Home Owners Need Year-Round Boxes

This pattern drives PO Box adoption in a way that's distinct from rural isolation. The 65 active PO Boxes serve just 12 year-round households, producing an adoption rate of 5.42. That doesn't mean local residents are underserved. Instead, it reflects second-home owners who maintain year-round boxes for tax bills, property notices, and off-season correspondence while they're hundreds of miles away.

Property Investment and Postal Infrastructure

The median home value of $114,800 is modest compared to other vacation destinations, but the investment in permanent mailing addresses tells the real story. When you own property on an island accessible primarily by boat, a PO Box isn't an inconvenience. It's infrastructure. Seasonal residents need a reliable address that doesn't depend on whether someone's at the property to collect mail from a dock-side box or waterfront cabin.

River Geography and Mail Delivery

County Route 6 provides the only street delivery in the ZIP4 system, serving a single address range. Everything else routes through the post office. The river geography makes traditional carrier routes impractical. Most properties sit along the shoreline or on small islands, where mail delivery by boat would be expensive and unreliable. The PO Box system works because it matches how people actually use these properties: intermittently, seasonally, and often from a distance.

Street Name Patterns

Minimal Street Infrastructure Waterfront Access Rural Routes

The single street record for County Route 6 reflects the island geography where most properties are accessed by water rather than traditional roads. The dominance of rural carrier routes indicates scattered, low-density development typical of island communities.
