Response Performance + Community Risk

This is the crossover: community risk data from your free profile, overlaid with your department's actual response times. Toggle between views to see where response is slowest relative to risk.

Showing simulated 90th percentile response times by census tract. Green = under NFPA target (6:20). Red = above target.

NFPA 1710 Compliance

Career departments target 90% of incidents within NFPA 1710 response time benchmarks. Here is how Berkeley's simulated data compares.

21 Coverage Gap Identifications Across 3 Risk Domains

Fire · EMS · Hazard

Tracts with Very High community risk and 90th percentile response times above NFPA 1710 targets. Some tracts appear across multiple domains — a tract with aging housing, elderly residents, and earthquake exposure is triply exposed. Not all gaps call for the same response. See the breakdown below.

Coverage Gaps by Risk Domain

Each gap domain cross-references community risk data from your free profile with actual response time performance. This is the crossover that tells you where to deploy CRR effort and why.

Fire Risk Gaps

7 tracts
~18,200 residents in high structural fire risk areas with slow response
  • Pre-1970 housing67%
  • Mobile/manufactured homes12%
  • Avg 90th %ile response7:08
  • Fire NRI ratingVery High

Old housing stock + slow response = preventable fatalities. These tracts are prime candidates for smoke alarm canvasses, home fire safety visits, and pre-fire planning coordinated with Stations 3 and 7.

EMS Risk Gaps

5 tracts
~11,400 residents with elevated EMS demand and slow response
  • Population age 65+28%
  • Disability rate19%
  • Uninsured rate14%
  • Avg 90th %ile response6:52

A 7-minute response to a cardiac arrest versus a 6-minute response isn’t a compliance gap — it’s a survival gap. These tracts are candidates for community paramedicine, fall prevention, and chronic care coordination to reach people before they need an ambulance.

Hazard Risk Gaps

9 tracts
~36,343 residents in Very High NRI earthquake & wildfire zones, response averaging 7:21
  • NRI overall risk score80+ (Very High)
  • Top hazardsEarthquake, Wildfire
  • Critical infrastructure3 schools, 1 hospital
  • Avg 90th %ile response7:21

Earthquake and wildfire zones with slow response are a planning and grant priority. This data supports BRIC/HMGP funding narratives, mutual aid agreements, and pre-positioned resource requests.

Station Performance by Risk Zone

Each station's response times compared to the community risk level it serves. Stations marked * are serving Very High risk areas while exceeding NFPA 1710 targets — the combination that most warrants operational review and targeted CRR investment.

Station Area Risk 90th %ile Response vs. NFPA Target Gap Tracts Calls/Mo
Station 1 — Downtown Moderate 5:42 ✓ On target 0 178
Station 2 — North Berkeley High 6:31 Over by 0:11 3 142
Station 3 — Claremont Hills * Very High 7:12 ✗ Over by 0:52 4 89
Station 4 — West Berkeley Moderate 5:55 ✓ On target 1 164
Station 5 — Elmwood * Very High 6:48 ✗ Over by 0:28 3 97
Station 6 — South Berkeley High 6:15 Near limit 2 133
Station 7 — Hills * Very High 6:58 ✗ Over by 0:38 2 74

* Flagged: Station serves a Very High risk area with 90th percentile response exceeding NFPA 1710 target. Priority for deployment review and CRR investment.

Berkeley Fire Department — Weekly Digest

Week of February 10–16, 2026  ·  Response + Risk Summary

Total calls this week 247 (+3% vs. prior week)
90th percentile response 6:08 — improved 0:12 ↓
NFPA 1710 compliance 85% (target: 90%) — up 2 pts ↑
Busiest station Station 2 — 52 calls (High risk zone)
Fire risk gap tracts 7 tracts — Stn 3 & 7 flagged
EMS risk gap tracts 5 tracts — 28% age 65+ in zone
Hazard risk gap tracts 9 tracts — earthquake/wildfire priority
CRR activities this week 2 — smoke alarm install (fire gap), WUI drill

This week’s insight: Station 3 coverage area had the department’s highest fire risk tracts this week and averaged 7:12 response — 52 seconds over NFPA target. Pre-fire planning for the Claremont Hills area and a home visit program in Tracts 60141 and 60143 would directly address the highest-exposure overlap. Two CRR activities were logged this week; both were in gap tracts. Keep it up.
