Seattle Public Utilities safety composite

Seattle Public Utilities scores strongest on fatalities (safer than 51% of same-industry peers) and weakest on dart rate (safer than 31%), blended into one 0-100 breakdown against same-industry peers.

This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
