Risk Overview

About Natural Disaster Risk in Richmond County, New York

Richmond faces moderate-to-high risk

Richmond County scores 91.00 on the composite risk scale, placing it in the Relatively Moderate category but near the top of that band. This score exceeds the national average and signals genuine multi-hazard exposure, particularly from coastal and seismic activity. Richmond's risk profile demands serious preparation despite the "moderate" label.

Second-highest risk in New York State

Richmond County ranks second in New York's hazard hierarchy with a score of 91.00, trailing only Queens County at 99.17—31% above the state average of 69.42. This position places Richmond among the state's most vulnerable communities. Only one New York county carries demonstrably higher disaster risk.

Riskier than all nearby counties

Richmond (91.00) outpaces Rockland County (88.42) and sits well above Saratoga (73.03) and Schenectady (71.28). Among counties within reasonable distance, Richmond stands as the clear leader in composite risk exposure. This isolation at the top of the regional risk chart underscores local hazard intensity.

Coastal threats and earthquakes dominate

Flood risk scores 91.95 and hurricane risk hits 90.24, reflecting Richmond's exposure as a Staten Island-based county surrounded by water. Earthquake risk (91.83) adds critical seismic vulnerability. These three hazards together create a uniquely challenging risk profile for the region.

Flood and wind coverage are essential

With flood risk at 91.95 and hurricane risk at 90.24, NFIP flood insurance and windstorm coverage are non-negotiable for Richmond homeowners. Earthquake insurance deserves serious consideration given the 91.83 risk score. Bundle these protections and review your policy annually, especially before hurricane season.

Preparedness Context

Richmond County's top natural hazard is flood risk, ranked at the 92th percentile nationally. Homeowners here should confirm whether they are in a FEMA-designated flood zone and check if standard homeowners insurance covers flood damage — it typically does not. The county's second-ranked hazard, earthquake at the 92th percentile nationally, means Richmond County residents face compounding risks from multiple natural hazard types during peak seasons. For most Richmond County households, the highest-return preparedness step is storing critical documents in digital cloud backup combined with a pre-designated family meeting point if communication is disrupted.

Regional Context

Richmond County's composite risk score sits 21.6 points above the New York county average, placing it among the more hazard-exposed counties in the state.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Richmond County higher risk than average?
Richmond County's composite risk score of 91th percentile is above the New York state average of 69th percentile. This elevated risk is driven by flooding exposure (92th percentile), along with earthquake and hurricane and tornado risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
