Catalogue assessment and metadata evidence

Assessment recorded

Completed catalogue decisions are recorded separately from technical inspection and scientific validation. Access and metadata evidence retain their original dates and scope.

Completed catalogue assessment

Eligibility decision: Include · Included Documentary Evidence
Assessment date: 28 September 2026
Decision reason: The original 7-page IRDR special report is a corridor debris-flow risk assessment. Its long-term susceptibility and infrastructure exposure findings are contextual; do not relabel them as a measured event-specific length of destroyed road.
