Stormwater Maintenance LLC: 3.0 TCR = 109% of Drainage project construction BLS 2.8 · 2y Form 300A (see methodology below)

Stormwater Maintenance LLC safety composite

Stormwater Maintenance LLC scores strongest on dart rate (safer than 73% of same-industry peers) and weakest on total case rate (tcr) (safer than 26%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
