The facility's mail system operates through 123 PO Boxes despite having only five occupied housing units. That dramatic imbalance makes sense for an institutional setting where each department, program, or unit needs its own mailbox. The post office maintains twice as many boxes as the entire population would suggest, reflecting the administrative and operational needs of running a large facility. Staff, vendors, contractors, and various departments all require separate mail delivery points.
Mail delivery to this location happens exclusively through Dutch Fork Road, which accounts for all 27 ZIP+4 carrier route records in the system. There's no network of streets or residential subdivisions here. Instead, the address system reflects a single-facility model where mail sorting depends on building designations and unit numbers rather than traditional house numbers. The facility sits within Richland County's northwestern section, enclosed within the broader 29036 ZIP code's service area.
The demographic profile confirms the institutional character. The median age of 82.3 suggests this may be a correctional healthcare facility or specialized care unit rather than a general prison population. Of the 213 residents, 180 identify as white, 25 as Black or African American, and smaller numbers in other categories. The five traditional households likely represent on-site staff housing or administrative residences. With an adoption rate of 24.6%, the post office serves a regional function beyond just the immediate facility population, suggesting that surrounding rural areas rely on White Rock boxes for mail service.
The single street designation reflects an institutional facility model where all addresses reference one access road rather than a network of residential streets.
