Storm System Risk Based Prioritization & Decision-Making: Asset risks are well understood and documented based on evidence of the
probability and the consequence of failure. Decisions made about assets and service
delivery are informed with appropriate and timely information, are transparent, and
are aligned with community priorities and long-term reliable service delivery.
