Service Area Overview
Your department boundary, station locations, and overall NRI risk scores by census tract. Use the sections below to explore specific hazards, fire risk indicators, and EMS demand drivers across your service area.
Service area, population, and census tract assignments are based on department boundaries from NERIS Public. Boundary accuracy varies by jurisdiction.
Natural Hazard Risk
What this means for planning: With a risk score of 98.1 (Very High nationally), wildfire is your leading natural hazard. Prioritize structure protection, evacuation route planning, and coordination with forestry agencies. Focus on defensible space enforcement, pre-positioning during red flag warnings, and community evacuation drills.

Demographics & Vulnerability
Why This Matters
Your community's demographics shape everything — from where you need smoke alarm programs to how many of your calls are EMS. The data below identifies who generates the most emergency demand, who faces the greatest barriers during emergencies, and who benefits most from targeted CRR outreach.
Age Distribution
Age drives EMS call volume (highest utilization: 65+ and especially 75+, with elevated rates also among children under 5), shapes fire safety education priorities, and determines evacuation assistance needs. The dark marker on each bar shows the national average.
Social Vulnerability Indicators
These indicators identify populations that need additional support during emergencies, face barriers to self-evacuation or medical access, and benefit most from proactive CRR programming.
| Vulnerability Factor | Your Community | Peer Average | National Average | vs. Peers |
|---|---|---|---|---|
| Disability Rate Higher EMS utilization, evacuation assistance needs, accessible communication requirements |
11.3% | 13.6% | 13.4% | slightly lower |
| Poverty Rate Economic barrier to safety resources |
6.7% | 9.9% | 12.4% | slightly lower |
| Uninsured Rate May delay medical care, leading to emergencies |
4.8% | 5.9% | 8.2% | slightly lower |
| Limited English Households Language barrier to emergency communication |
2.9% | 3.6% | 4.2% | slightly lower |
| No Vehicle Access Transport-dependent for evacuation |
1.9% | 4.2% | 8.5% | 2.2x lower |
| No Internet Access Disconnected from digital emergency alerts |
3.1% | 4.5% | 6.6% | slightly lower |
Economic Context
Fire Risk Factors
What this means for planning: 12.3% of housing units are vacant — slightly higher the national average. Vacant properties have elevated fire risk due to lack of maintenance, unauthorized access, and delayed detection. Work with code enforcement on vacant property inspections and securing abandoned structures.
How to read this map: Colors show relative risk within your jurisdiction (red = highest-need tracts, green = lowest-need). Check the table below for overall levels vs. peers and national averages.
| Risk Factor | Your Community | Peer Average | National Average | vs. Peers |
|---|---|---|---|---|
| Pre-1980 Housing Pre-1980 construction standards |
33.7% | 23.8% | 36.0% | slightly higher |
| High-Risk Heating Wood, fuel oil, coal |
6.6% | 6.2% | 5.7% | ≈ average |
| Vacancy Rate Vacant properties at higher fire risk |
12.3% | 8.0% | 10.3% | 1.5x higher |
| Mobile Homes Structural fire spread risk |
11.0% | 7.3% | 5.8% | slightly higher |
| Renter-Occupied Higher turnover, variable maintenance |
16.1% | 28.4% | 34.4% | 1.8x lower |
EMS Risk Factors
EMS typically accounts for 60-80% of fire department call volume nationally. The demographics below are the strongest predictors of where that demand comes from in your service area.
What this means for planning: Your community demographics suggest moderate EMS demand. Focus on efficient response protocols, NFPA compliance tracking, and community paramedicine programs to expand your role in public health and preventive care.

19.9% | 19.4% | 17.4% | ≈ average |
| Disability Rate Higher EMS utilization, specialized assistance needs |
