Flash flooding from heavy rainfall events dominates the flood character of Richmond County. Recent examples include widespread catastrophic flash flooding on September 1, 2021, due to extremely heavy rainfall from the remnants of Hurricane Ida, and flash flooding on July 31, 2025, which resulted in stranded vehicles and road closures. Coastal flooding also presents a risk, with events on January 13, 2024, and January 10, 2024, causing widespread moderate to major coastal flooding along the coastline and the Lower Hudson River.
National Flood Insurance Program data indicates that properties in Zone A have experienced the highest average claim payouts and water depths. Homeowners in coastal areas, those located near rivers, and properties situated in zones with lower Base Flood Elevations (BFE) should pay particular attention to flood risk.
