In 2025, fire departments serving Arnold responded to 36 fire and hazmat incidents . Here's the full picture.
Incomplete 2025 data. Arnold's departments reported 36 incidents to NFIRS for 2025, against about 95 in a typical year, so 2025 figures on this page undercount. The 2021–2025 totals are the better guide.
Building fires lead by count. Building fires lead by dollars. Together the top five categories make up about 64% of all calls.
Mar peaks. Sep dips. Watch for the typical fall climb starting in October.
475 incidents 2021–2025. Peak year was 2022. $4.1M cumulative property loss. 2 civilian deaths.

* Well below Arnold's usual volume. That almost always means one or more departments didn't submit a full year to NFIRS, not that fires dropped, so no year-over-year change is shown for it.

A 30-minute weekend can cut your home's exposure substantially. These four checklists are a good starting point.
Numbers reflect incidents reported by participating fire departments to the National Fire Incident Reporting System (NFIRS) Public Data Release for calendar year 2025. NFIRS is voluntary — about 23,000 of roughly 30,000 US fire departments report — so totals are a strong indicator, not a complete census. Per-capita comparisons use 2023 ACS population estimates. Wildland fire data complements NFIRS with NIFC and USFS perimeters. Active-fire counts come from a dated NIFC snapshot, not a live feed.
