Arlington County is a dense urban area directly across the Potomac River from Washington DC. Four Mile Run and Lubber Run are local waterways that can flash flood during heavy rain events. The county is highly urbanized with significant impervious surface coverage, leading to rapid stormwater runoff. Post-war garden apartments (1950s–1960s) and older Federal-style row houses have aging plumbing infrastructure. Arlington has among the highest real estate values in Virginia, making restoration costs per job among the highest in the state. Hurricane Ida remnants (2021) caused significant basement flooding throughout the DC metro area.
Flood-prone areas: Barcroft and Douglas Park near Four Mile Run have highest flood risk. Clarendon and Rosslyn are premium high-rise areas. Lyon Village and Old Glebe are single-family residential with older housing stock.
