Introduction
Zero tolerance and trigger-depth policies serve different risk profiles. Your mix should reflect site usage, liability exposure, and budget priorities.
Key Points
- Zero tolerance maximizes safety and minimizes slip risk—ideal for high-traffic sites.
- Trigger depths (e.g., 2 inches) reduce dispatch frequency and cost for lower-risk areas.
- Hybrid models are common: sidewalks zero-tolerance, lots at 2 inches.
- Define thresholds by zone and document them on site maps.
- Revisit policy mid-season based on incident data and weather trends.
Practical Advice
Adopt zero-tolerance near entrances, medical facilities, and 24/7 operations to protect pedestrians. Use trigger depths on remote lots and low-traffic zones to control spend.
Set clear escalation rules: when to pre-treat, when to plow, and when to haul. Ensure your contractor’s logs capture arrival/finish times and materials for claims support.
Communicate policies to tenants and staff so expectations match the service plan.
Conclusion
Meet with your contractor to map zones, assign thresholds, and publish a simple winter policy for your teams.

Technical Overview
- Policy → dispatch. Telematics and weather feeds raise alerts at your thresholds; dispatch combines those with crew locations to decide who rolls next.
- Why hybrids work. Sidewalks drive liability, lots drive cost—splitting policies aligns attention and budget.
- Documentation loop. Photos + timestamps + materials create defensible records if a claim arises.
