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 79.9 (Relatively High nationally), lightning is your leading natural hazard. Focus on outdoor event safety protocols, wildfire ignition response, and public education. Coordinate with emergency management on warning dissemination.

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 |
16.2% | 14.0% | 13.4% | slightly higher |
| Poverty Rate Economic barrier to safety resources |
21.6% | 14.0% | 12.4% | 1.5x higher |
| Uninsured Rate May delay medical care, leading to emergencies |
12.0% | 8.1% | 8.2% | slightly higher |
| Limited English Households Language barrier to emergency communication |
1.4% | 3.2% | 4.2% | 2.3x lower |
| No Vehicle Access Transport-dependent for evacuation |
7.7% | 6.5% | 8.5% | slightly higher |
| No Internet Access Disconnected from digital emergency alerts |
6.9% | 5.8% | 6.6% | slightly higher |
Economic Context
Fire Risk Factors
What this means for planning: Focus fire prevention efforts on cooking safety (leading cause of home fires), heating equipment safety, electrical hazards, and smoke alarm installation programs. Target education toward renters and multi-family buildings where fire incidence is typically higher.
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 |
52.3% | 30.2% | 36.0% | 1.7x higher |
| High-Risk Heating Wood, fuel oil, coal |
0.6% | 0.3% | 5.7% | 1.9x higher |
| Vacancy Rate Vacant properties at higher fire risk |
8.8% | 7.5% | 10.3% | slightly higher |
| Mobile Homes Structural fire spread risk |
5.3% | 2.5% | 5.8% | 2.1x higher |
| Renter-Occupied Higher turnover, variable maintenance |
50.0% | 40.2% | 34.4% | slightly higher |
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: Economic barriers to healthcare access (poverty: 21.6%, uninsured: 12.0%) can lead to delayed treatment and preventable emergencies. Partner with federally qualified health centers and social services to connect vulnerable residents with primary care resources.
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 |
|---|---|---|---|---|
| Population 65+ Highest EMS utilization group |
16.1% | 16.4% | 17.4% | ≈ average |
| Disability Rate Higher EMS utilization, specialized assistance needs |
16.2% | 14.0% | 13.4% | slightly higher |
| No Vehicle Access Transport-dependent for medical access |
7.7% | 6.5% | 8.5% | slightly higher |
| Uninsured Rate May delay care, leading to emergencies |
12.0% | 8.1% | 8.2% | slightly higher |
| Poverty Rate Economic barrier to healthcare access |
21.6% | 14.0% | 12.4% | 1.5x higher |
Critical Infrastructure Protected
Hospitals, schools, nursing homes, and childcare centers require pre-incident plans and specialized evacuation protocols. These counts go directly into AFG/SAFER grant narratives and CPSE/CFAI Standards of Cover documentation.
