Fresno sits on the floor of the San Joaquin Valley where the Kings River and San Joaquin River watersheds collect runoff from the entire western Sierra Nevada. Atmospheric river events in 2017 and 2023 caused widespread flooding across Fresno's low-lying central and southwest neighborhoods. The city's adobe-like clay soils become saturated quickly and hold water for days after storm events end, creating prolonged foundation seepage and perimeter flooding
Flood-prone areas: Highest flood risk: Southwest Fresno neighborhoods with older infrastructure, Tower District and Central Fresno near downtown drainage infrastructure, and any area with 1950s-1970s original plumbing that has not been updated
