De-icing salt calculator for parking lots
One row per surface: its length and width. Enter your application rate: the calculation gives the salt per application and for the season. Optionally, compare the fresh snow of one storm with the room in your storage zone.
Published parking lot rates (reference)
A published parking lot table by pavement temperature, cited as a guide: your rate stays yours. Salt works poorly below about 14 °F (-10 °C).
| Pavement temperature | lb per 1,000 sq ft | kg per 100 m² |
|---|---|---|
| Above 30 °F (-1 °C) | 3 | 1.5 |
| 25 to 30 °F (-4 to -1 °C) | 5 | 2.4 |
| 19 to 25 °F (-7 to -4 °C) | 6 | 2.9 |
| 16 to 19 °F (-9 to -7 °C) | 7 | 3.4 |
| 5 to 16 °F (-15 to -9 °C) | 8 | 3.9 |

How it is calculated
Area = length x width, added up for every surface. Salt per application = area x rate (lb per 1,000 sq ft, or kg per 100 m²). Salt for the season = salt per application x the applications planned. Fresh snow = area x storm depth, with no packing or melting. Storage zone = length x width x maximum pile height. No rate comes filled in: it is yours, by pavement temperature.
