Koreatown Water Damage — Frequently Asked Questions

What is the flood risk history in Koreatown, Los Angeles?

Koreatown dense mid-rise apartment corridor sits on flat terrain with poor natural drainage, making it one of the most water-damage-prone neighborhoods in central LA. The January 2023 atmospheric river dumped 4.7 inches of rain in 48 hours, overwhelming the aging combined sewer system and causing widespread basement flooding. Older apartment buildings from the 1920s-1960s with original galvanized plumbing experience cascading pipe failures every winter season. Primary cause: Koreatown sits in a drainage basin with minimal slope and extremely high impervious surface coverage — virtually 100% of rainfall becomes immediate surface runoff that overwhelms the aging storm drain network, which has not been upgraded to handle modern rainfall intensity.

What causes water damage in Koreatown?

Important: Koreatown has one of the highest concentrations of pre-WWII apartment buildings in Los Angeles. These buildings use original galvanized steel pipes that corrode from the inside out — often the first sign of failure is water staining on ceilings below upper-floor units.
