Where San Diego floods
On January 22, 2024, 2.73 inches of rain fell at San Diego International Airport, the wettest day in its record since 1939. Chollas Creek overflowed into Southcrest and Shelltown, and the county recorded 213 federal flood insurance claims for the year, with $19.9 million paid.
January 22, 2024
The storm came in fast on a Monday morning. Chollas Creek's channel filled and overflowed, and several feet of water moved through Southcrest and Shelltown (KPBS). NBC 7 reported that the storm displaced more than 1,200 people. A year later, some families were still rebuilding.
In the federal flood insurance record, ZIP 92113, which covers Logan Heights and Southcrest, has 125 claims on record, 102 of them since 2015. Claims only count homes that had a flood policy, so the count understates the damage.

Before the next big storm
- Find your flood zone on FEMA's map, and ask your agent about flood coverage either way. A new federal policy usually takes 30 days to start.
- Move valuables and papers off the floor in a garage or a ground-floor room.
- Know how to shut off power at the panel, and keep it reachable from a dry spot.
- Photograph your rooms now, for a contents claim later.
After flood water gets in
Flood water carries sewage and street runoff, so porous materials it touched usually have to go. Dry the structure within 24 to 48 hours if you can. Flood and sewage cleanup.
Questions San Diego homeowners ask
Was January 22, 2024 the wettest day ever in San Diego?
In the airport's daily record from 1939 on, which we analyzed, yes: 2.73 inches. The city's full weather record goes back to the 1850s, and a few older days in it may be wetter.
Does homeowners insurance cover creek flooding?
No. Flood water from outside is excluded from standard homeowners policies and needs a flood policy.
