NRI Risk Rating

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 98.2 (Very High nationally), cold wave is your leading natural hazard. Focus on cold-exposure emergency response, warming center partnerships, and proactive wellness checks for vulnerable populations during extreme cold events.

Top 5 Hazards in Your Service Area

Sorted by life-safety impact. Life-safety loss uses FEMA’s Value of Statistical Life ($13.7M per fatality or 10 injuries). NRI methodology

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.

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.

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.

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.
