How Often Have Hydrants Run Dry?
Evidence from Recent Major Wildfires
Researcher(s): Gregory Pierce, Jennifer Gorman, Edith de Guzman, Faith Kearns
Abstract:
The brief finds that hydrants running dry during major urban wildfires is common, not unique to the 2025 Palisades Fire. It argues that the larger issue is a mismatch between extreme wildfire demands and urban water systems that were not designed to meet them.
