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 99.7 (Very 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.

Fire Risk Factors

What this means for planning: 31.6% of housing units are vacant, 3.1x 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.

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: 26.9% of residents have a disability, 2.0x higher the national average. Residents with disabilities have higher EMS utilization and may require specialized evacuation assistance, accessible communication during emergencies, and coordination with social services. Consider functional needs assessments in pre-incident planning and partnerships with disability advocacy organizations.
