62/ 100 — Moderate watch band
Lower elevation band → higher sensitivity to pluvial / drainage stress in some climates.
Higher median context often correlates with larger conditioned envelopes and specialty systems—maintenance checklists tend to be longer.
County anchor (Contra Costa County) is used only to keep cohort narratives locally grounded—not as a regulatory signal.
The line is a deterministic visualization derived from this page's stable seed plus the index above. It
