Storm Runoff and Flash Flood Cleanup: what to know
Altadena averages about 21 inches of rain a year, more than the basin below, and most of it lands in a handful of winter storms. On a slope that water moves fast: it crosses uphill yards, runs down driveways and gathers against the first door, garage slab or foundation vent in its way. Once it is inside, it counts as Category 3, because it picked up soil, oil and debris on the way.
Where runoff gets in on a hillside lot
- Door thresholds and sliders that face uphill
- Garage slabs that sit below the driveway grade
- Foundation vents that open into a crawl space
- Lower rooms cut into the slope
Each entry point changes the plan, so the inspection follows the water from outside to the last wet room.

Runoff carries silt and bacteria into carpet, pad, drywall and insulation. Under IICRC S500, porous materials soaked by Category 3 water are removed and bagged, hard surfaces are cleaned and treated with an EPA-registered antimicrobial, and only then does structural drying start. Silt left in a crawl space keeps the soil wet, so it is cleared before the drying equipment goes in.
Storm records that shape the plan
March 2, 1938 brought 7.70 inches of rain in 24 hours, and February 1980 brought 19.70 inches in one month. After a wet stretch the hillside is saturated, so later storms send more water downhill. FloodSmart explains flood coverage, and the National Weather Service flood safety pages cover what to do while water is moving.
Before the crew arrives
Shut the water off at the fixture valve or the main, keep clear of wet outlets and cords, and take photos before anything is moved or thrown out.

Storm Runoff and Flash Flood Cleanup questions in Altadena, CA
Still dealing with it?
Runoff came in under the door? The cleanup crew handles it as Category 3.
(888) 578-6508 (888) 578-6508Have the muddy water clearedIs storm runoff treated as clean water?
No. Water that crossed soil, pavement or a yard is Category 3. Soaked carpet, pad, drywall and insulation are removed rather than dried.
Does homeowners insurance cover runoff from a storm?
Water that entered from outside at ground level is usually treated as flood, which needs a separate flood policy. Check your own policy and talk with your insurer.
Why did water reach the house when the street did not flood?
On a slope, water from uphill lots follows the grade across yards and driveways. A downhill house can take water even when the gutter in front looks normal.
Can the crawl space be dried after runoff gets in?
Yes. Water is pumped out, silt and wet insulation are removed, surfaces are treated, and the joists and subfloor are dried with dehumidifiers and air movers.
How long does storm cleanup take?
Removal and cleaning take one to two days, then drying runs four to seven days for most houses, longer with plaster or a wet crawl space.
Storm water inside the house?
Runoff carries silt and bacteria into everything it touches. The crew removes what is soaked, disinfects and dries the structure.
