residential receiving-area property-line noise limit, day / night, enforced by Northern Virginia counties (Prince William, Stafford)
60 / 55 dBAobserved
| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | Residential receiving-area limits at the property line; industrial-district limits differ (Prince William’s October 2025 industrial rewrite: 73 dBA day / 68 dBA night) and the permit’s averaging time, tonal and band conditions govern acceptance. Chapter 6.8’s worked case adopts this pair as its receptor criterion. |
