Buffalo Creek sits in the forested foothills southwest of Denver, a small mountain community of 273 residents spread across 47 square miles of Jefferson County. This isn't a typical Colorado mountain town. It's a quiet refuge where the median age is 57 and nearly half the homes sit vacant most of the year, owned by people who visit seasonally.
Mail arrives by rural carrier, not PO Box. One rural route and one highway contract route serve the scattered homes along county roads and mountain trails. S Buffalo Creek Rd has the most addresses (10 ZIP+4 records), followed by County Road 126 and County Road 96. Street names like Lincoln Ave, Harrison Ave, Grant Ave, and Sherman Ave hint at the community's historic roots, though most delivery points use county road designations.
This is a well-educated, middle-income mountain community. About 64% of adults hold bachelor's degrees or higher. Median household income sits at $80,125, with home values around $509,200. Most residents own rather than rent (97 owner-occupied units vs 11 renter-occupied). The community operates a Community Post Office (facility code C), serving the permanent population and seasonal residents who return to their cabins throughout the year.
Buffalo Creek doesn't have city carrier delivery. The ZIP was classified as PO Box only before October 2004, but this isn't a PO Box Only Zone. Residents receive mail at their physical addresses via rural and highway contract carriers who navigate the winding mountain roads.
Mix of county road designations and streets with presidential names (Lincoln, Harrison, Grant, Sherman, Logan) alongside nature-themed roads.
