Put plowed snow where the meltwater can leave without crossing pavement. Four placements look convenient and each one fails at melt, usually at the same spot every year.

What you need A site plan with the inlets, culverts, driveway mouths and sight lines marked; a can of marker paint; the operator briefed on the four cases.
[['Over an inlet or culvert', 'Ponding, then refreezing on the road', 'Drain repair plus a complaint every year'], ['Across a driveway mouth', "Access blocked by the plow's own row", 'Resident clears it into the road; the road gets worse'], ['Along an intersection sight line', 'The row becomes a screen for cross traffic', 'Collision risk that is invisible until it is not'], ['On a slope above the road', 'Meltwater crosses the pavement', 'Black ice at the same location, days after the melt starts']]

Steps
- Mark the inlets, culvert mouths, driveway mouths and intersection sight lines on the ground before the first snow. Paint, not a note in a folder.
- Choose the storage area first, and choose it for drainage: the meltwater has to leave without crossing pavement.
- Plow toward the storage area on every pass, so the row never has to be moved twice.
- Re-check the sight lines after each storm, not once a season.
- After the first melt, walk the site and find where the water went. That is the only honest test of the placement.
Why the same spot ices every year
| Symptom | The placement behind it | What to change |
|---|---|---|
| Ice at one culvert each spring | Row capped the inlet | Move the row and mark the inlet |
| Ice on a bend after a warm day | Row on a slope above the road | Move the row to the low side, or open a channel |
| Ice at a driveway every melt | Row across the mouth | Leave the mouth open on the last pass |
The argument the manual will make
The manual holds that the fix for repeated ice at one location is a painted marker rather than another briefing, because the failure recurs at the same place, which means the information is knowable and simply not where the operator is looking. Training fades; paint does not.
