Key Facts
  • This is a PO Box Only Zone. There's no alternative mail delivery option in Coal Creek.
  • With 159 PO Boxes serving 138 households, the post office has about 15% more boxes than homes, serving some residents from surrounding areas.
  • Nearly 38% of workers here work from home, more than triple the national average, suggesting residents chose this remote location intentionally.
  • 84% of homes are owner-occupied, indicating a stable, long-term residential community rather than a rental market.
  • About 36% of housing units are mobile homes, reflecting the affordable, rural character of the community.
  • The median household income of $41,000 runs below Colorado's state average, but lower housing costs offset the difference.

Community Overview

Coal Creek sits in a narrow valley in Fremont County, about 18 miles southwest of Colorado Springs. This is a PO Box Only Zone. There's no street delivery alternative here, so every household picks up mail at the post office.

Postal Services

The post office maintains 159 PO Boxes for 138 occupied homes. That 115% adoption rate makes sense: some households keep multiple boxes, and a few residents from surrounding areas use this location too. It's classified as LOCAL_WITH_REGIONAL because service extends beyond the immediate community.

Rural carrier routes (2 distinct routes) handle deliveries to addresses outside the immediate townsite, but PO Boxes remain the primary mail access point for Coal Creek proper.

Local Character

Coal Creek has 334 residents and covers just 1.2 square miles. The median age is 47.8 years, and 84% of homes are owner-occupied. About 36% of housing units are mobile homes, and the median home value is $205,300.

One striking statistic: 37.9% of workers here work from home. That's more than triple the national average. The remote location and rural character attract people who don't need to commute.
