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 86.3 (Very High nationally), flooding is your leading natural hazard. Prioritize swift water rescue training, high-water vehicle rescue protocols, and coordination with emergency management on flood-prone area mapping and evacuation routes.

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 |
14.4% | 13.2% | 13.4% | ≈ average |
| Poverty Rate Economic barrier to safety resources |
20.7% | 11.6% | 12.4% | 1.8x higher |
| Uninsured Rate May delay medical care, leading to emergencies |
3.4% | 3.9% | 8.2% | ≈ average |
| Limited English Households Language barrier to emergency communication |
28.9% | 7.9% | 4.2% | 3.7x higher |
| No Vehicle Access Transport-dependent for evacuation |
28.4% | 11.6% | 8.5% | 2.5x higher |
| No Internet Access Disconnected from digital emergency alerts |
10.3% | 6.0% | 6.6% | 1.7x higher |
Economic Context
Fire Risk Factors
What this means for planning: 74.0% of housing units are renter-occupied. Rental properties often experience higher fire incidence due to transient occupancy and variable maintenance. Partner with landlords on smoke alarm compliance, tenant fire safety education, and rental property inspections.
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 |
70.1% | 65.9% | 36.0% | ≈ average |
| High-Risk Heating Wood, fuel oil, coal |
5.7% | 19.3% | 5.7% | 3.4x lower |
| Vacancy Rate Vacant properties at higher fire risk |
3.2% | 5.3% | 10.3% | 1.7x lower |
| Mobile Homes Structural fire spread risk |
0.1% | 0.3% | 5.8% | 2.7x lower |
| Renter-Occupied Higher turnover, variable maintenance |
74.0% | 47.1% | 34.4% | 1.6x 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: 28.4% of households lack vehicle access — 3.3x higher the national average. High rates of transport dependence correlate with increased EMS demand. Consider community paramedicine programs, partnerships with social services and Medicaid transport providers, and advocacy for non-emergency medical transport alternatives.
