Redacted counties. Real geometry.

Operational clients don't want their response gaps published — so names, coordinates, and case numbers are redacted. What stays is the part that matters: the geometry, the method, and the numbers the work produced.

§ 01 — CASE FILE Nº 05
FEB 2026 · REDACTED COUNTY, CO PUBLISHED

Re-positioning a SAR team on slope, not road.

A rural county's SAR response sectors were drawn from the road network — asphalt-distance — because road data is clean and terrain data isn't. We pulled 18 months of incident logs and re-ran every staged response against terrain-distance: slope, surface by season, snow and ice windows. About 14% of calls had a closer unit that was never dispatched.

The rebuild took a weekend. Across the first eleven incidents on the new sectoring, mean recovery time dropped 28% — a real number from a small sample, published with that caveat attached.

WHAT WAS DELIVERED
  • Revised sector maps — gridded by terrain-distance, with seasonal overlays
  • A one-page decision rule for IC — laminated, lives on the wall
  • A terrain-weighted assignment layer for CAD, refreshed quarterly and during named risk windows

Case files publish when redaction allows.

Every engagement produces a written deliverable; not every deliverable can be published. When one can, it lands here and in Field Notes — geometry intact, identities removed.
