A defensible route is one where you can demonstrate what you knew, when you knew it, and what you did with that knowledge.
Defensibility is not about being right — it's about being able to show your work.
A defensible route decision includes:
Evidence of Due Diligence** - Field surveys with dated photos - Documented measurements - Verified regulatory requirements
Traceable Decision Chain** - Clear record of alternatives considered - Documented rationale for route selection - Identified risks and mitigation measures
Audit-Ready Documentation** - Version-controlled data - Timestamped changes - Preserved original survey data
When something goes wrong — a delay, a damage claim, a permit violation — the question becomes: "Did you do the work?" A defensible route lets you answer "yes" with evidence.
