San Francisco's water table sits just feet below ground in many neighborhoods, especially near the bay and in former marshland areas like the Mission and SOMA. When winter rains saturate the soil, hydrostatic pressure forces water through foundation cracks, floor joints, and aging sewer laterals. Homes built on fill dirt face even higher risk because the soil compacts unevenly and creates pathways for groundwater intrusion. Basement flood cleanup becomes essential during El Niño years when rainfall exceeds drainage capacity and aging infrastructure cannot handle the load.
