Editorial analysis

Why this record matters

The subject matters to the places & architecture register because the source frames it as census-designated place in Arapahoe County, Colorado. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q9058142. Authority coordinates are 39.680, -104.114. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2020 and 2010.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
