Located at the confluence of the York River and the Chesapeake Bay, Yorktown, Virginia, faces a multi-faceted risk from hurricanes, one that arises from its coastal location, minimal elevation, and history of high-impact storm events. Given that Yorktown sits at sea level, and in certain areas, below sea-level, it is particularly susceptible to hurricane-induced storm surges, triggering flooding, infrastructure damage, and disruption of essential services. Coupling this with heavy rainfall that hurricanes typically bring, the town is also at risk of riverine flooding from the York River. Riverine and coastal inundation risks are heightened during high tide periods. Moreover, high wind speeds can inflict damage on buildings and other structures, disrupt power supply, and turn wind-borne debris into dangerous projectiles. In the past 30 years, Yorktown has experienced several hurricane and flood events, most notably Hurricanes Isabel in 2003 and Irene in 2011. Hurricane Isabel made landfall as a Category 2 storm causing significant damage due to strong winds, flooding, and storm surge. Several areas were submerged under floodwaters, extensive power outages occurred, and multiple structures were damaged. Noteworthy as well was Hurricane Irene which resulted in a 5-7 feet storm surge in and around Yorktown and caused widespread flooding. Given this history, any hurricane threat assessment should recognize Yorktown's vulnerability to major storms and resultant flooding, and prioritize community preparedness and adaptive infrastructure interventions.
