First steps for winter storm and flash flood cleanup in San Diego
Stay out of floodwater
Creek and storm drain water can carry bacteria, so avoid wading and keep pets out.

Switch off power to flooded rooms only if the panel stays dry.
Lift belongings up
Raise small items and papers to higher shelves.
Photograph the water level
Wide photos of water marks on walls document the depth for the claim.
Coastal San Diego averages about 10.65 inches of rain a year, so one intense storm can flood homes in hours. On January 22, 2024, about 3 inches fell in six hours, and floodwater entered ground floors across the southeast part of the city.
What does winter storm and flash flood cleanup cost in San Diego, CA?
Storm flood cleanup usually costs $3,000 to $25,000 or more, since floodwater is Category 3 and the total follows how much of the ground floor was covered and how long it stayed wet.

How winter storm and flash flood cleanup is handled in San Diego
The tech who does the walkthrough maps moisture before any equipment goes down, so the drying plan matches what is actually wet. Equipment stays until the readings say dry, not until it looks dry.
- 01
Remove the debris
Mud, silt and soaked materials go out first.
- 02
Clean and treat
Surfaces are washed and treated before drying.
- 03
Open and dry
Flood cuts and equipment dry the framing.
- 04
Verify
Readings confirm the structure is dry.
Where the January 2024 water went
The worst county flooding that month hit Southcrest, Encanto, Mountain View and Lincoln Park, with Rolando and Shelltown also flooded, and floodwater inside some homes reached shoulder height. More than 1,200 people were displaced.
Why the creek matters
Chollas Creek is the largest watershed in San Diego County, and much of it was channeled with concrete in the 1970s, which risks overflow when debris builds up. The Stormwater Department tied the 2024 flooding to heavy rain and an aging stormwater system.
What the cleanup involves
- Mud and silt shoveled and vacuumed out
- Carpet, pad and wet drywall removed
- Surfaces cleaned and treated with antimicrobial
- Contents sorted into keep, clean and discard
Floodwater is handled as Category 3, so the crew works behind containment and removes porous materials rather than trying to dry them. When sewage is part of the mix, the work follows sewage backup cleanup.
Drying after the water is gone
With the debris out, flood cuts open the lower walls, and air movers and LGR dehumidifiers dry the framing and subfloor, with readings recorded until the structure is dry. Water left under raised floors is covered by crawl space water removal.

Winter Storm and Flash Flood Cleanup questions in San Diego, CA
Still dealing with it?
Floodwater in a San Diego ground floor needs removal before it settles in
(888) 450-9281Silt and mud outIs storm floodwater contaminated?
Yes. Water from creeks and storm drains carries bacteria and silt, so it is treated as Category 3 and porous materials are removed.
What happened in San Diego in January 2024?
About 3 inches of rain fell in six hours on January 22, 2024, and the flooding displaced more than 1,200 people and damaged thousands of homes.
Will the Chollas Creek project end flood risk?
Phase one of an $11 million restoration along Federal Boulevard began on June 26, 2026, but a flooded home still needs prompt cleanup.
What helps a flood claim?
Dated photos of water marks, readings from each visit and a list of discarded items give the adjuster a clear picture.
Does flooding near the Tijuana River Valley differ?
Floods there can carry sewage, so work near Nestor and San Ysidro assumes contamination and uses containment from the start.
Describe how deep the water got and which rooms are wet.
The response team removes the silt, cuts out what floodwater soaked and dries the structure with readings logged until it is dry.
