Stormwater Inspection

Why Accurate Rainfall Matters for Stormwater Inspections

Stormwater inspections rely on defensible, timestamped rainfall records. Manual gauges and scattered online sources often introduce errors—especially when inspectors require documentation of 0.1", 0.25", 0.5", or 1.0" qualifying rain events.

To support compliance, inspectors need site-specific rainfall totals they can trust, backed by National Weather Service (NWS) data.
