This isn't traditional resort infrastructure with lodges and ski lifts. It's a cluster of second homes and seasonal retreats tucked into the mountains west of Boulder. Highway Contract Route service exists for a handful of addresses on Pinecliff Road and Herlerri Road, but 125 people chose PO Boxes instead. When your property sits empty eight months a year, a year-round box makes more sense than hoping packages wait on an unoccupied porch.
The 37 residents who call Pinecliffe home year-round maintain a median age of 43.3 years. The community skews slightly older than Colorado's median, which fits the second-home pattern. Working professionals and early retirees who can afford mountain retreats tend to fall in that age range. The Post Office building on Pinecliff Road serves as one of the few named delivery points in the ZIP4 data, anchoring a service area that extends well beyond the visible community.
With just two streets in the ZIP4 records, Pinecliffe's delivery infrastructure reflects its role as a tiny mountain retreat. Pinecliff Road dominates with two separate ZIP+4 segments, while Herlerri Road appears once. The minimal street network and complete absence of secondary unit types (apartments, suites) confirm this is exclusively single-family seasonal housing territory.
ZIP Code 80471 has 37 residents and 11 households (average 3.36 persons per household). The median age is 43.3 years, older than the state (37.2) and older than the nation (38.8). The gender split is 59.5% male and 40.5% female, which is much higher than the national male share (49.1%), making this a male-majority area. Largest groups are White (81.1%, much higher than the state average of 70.7% and well above the national average of 61.6%) and Asian (5.4%); Hispanic or Latino residents make up 2.7%, which is much lower than the state average (21.9%).
