That gap tells the story. Of the 20 total housing units here, 8 sit vacant for seasonal or recreational use. That's 40% of all homes. The adoption rate of 11.67 means the post office serves nearly 12 times as many boxes as there are local households. Second-home owners, nearby rural residents without carrier delivery, and business operators all rent boxes at this location.
The street layout shows the community's mixed character. State Highway 104 runs through with two separate ZIP+4 records, serving as the main corridor. Streets like Gamble Avenue NE and Rainier Avenue NE form the historic core, while roads like NE North Power Drive and NE South Power Drive suggest more recent development. The post office also serves one named building: Postmaster.
Delivery here combines urban and rural patterns. The ZIP has 2 city carrier routes and 14 rural routes, plus 8 dedicated PO Box routes. That's 24 distinct carrier routes serving what looks on paper like a tiny population. The routes extend across surrounding areas where street delivery isn't available, making Port Gamble a regional postal hub for the northern Kitsap Peninsula.
State Highway 104 dominates as the main corridor with multiple delivery segments. Historic street names like Gamble and Rainier reference the lumber mill heritage, while Power Drive roads indicate newer infrastructure. The NE directional prefix is consistent across nearly all streets, typical of planned company towns.
