Risk Overview

About Natural Disaster Risk in Delaware County, New York

Delaware County faces moderate disaster risk

Delaware County's composite risk score of 83.33 places it well above the national average, earning a relatively moderate risk rating. The county's exposure is driven primarily by significant flood danger (91.19) and hurricane vulnerability (76.85). This above-average positioning requires thoughtful, multi-hazard disaster preparedness.

Higher risk than most New York counties

At 83.33, Delaware County scores substantially above New York's state average of 69.42, placing it among the state's higher-risk counties. This elevated standing compared to statewide patterns reflects Delaware's geographic exposure to multiple significant hazard types. The county's risk profile demands serious attention to insurance and emergency planning.

Second-highest risk in this regional group

Delaware's 83.33 score ranks second only to Dutchess County (88.26) and Erie County (97.68) in this comparison group, substantially exceeding safer counties like Cortland (51.24) and Clinton (68.80). This elevated exposure relative to immediate neighbors reflects Delaware's particular geographic vulnerability. Your county faces more complex and serious disaster risks than most surrounding areas.

Flooding dominates Delaware's hazard profile

Delaware County faces exceptional flood risk (91.19), among the highest in the nation, making this hazard your paramount concern. Hurricane exposure (76.85) and tornado risk (55.60) add significant secondary threats. These three hazards account for the majority of Delaware's elevated composite risk.

Flood insurance is absolutely critical

Your county's extraordinary flood risk (91.19) makes flood insurance through the National Flood Insurance Program non-negotiable, regardless of property elevation or mortgage lender requirements. Supplemental wind and hail coverage protects against hurricane and tornado exposure (76.85 and 55.60). Professional flood risk assessment specific to your property location is essential before purchasing or selling.

Preparedness Context

Flood risk is Delaware County's top hazard at the 91th percentile nationally.

The county's second-ranked hazard, hurricane at the 77th percentile nationally, means Delaware County residents face compounding risks from multiple natural hazard types during peak seasons. Households across Delaware County should identify the nearest community shelter and keep a basic emergency kit — water, non-perishable food, medications, flashlight, and battery radio — in a location easy to grab quickly.
