What every winter storm and hillside runoff cleanup job includes
Extraction comes first
Truck-mounted and portable extractors pull free water before any fan goes down, since lifting liquid water out is far faster than evaporating it.
Dried to IICRC S500
Air movers and LGR dehumidifiers are sized to the class of loss, and the equipment stays until readings sit within 2 to 4 points of a dry reference.
A claim file built on site
Moisture maps, daily psychrometric logs and timestamped photos taken before any demolition give the adjuster a clear record of the loss.
Valley houses, valley habits
Slab floors with copper underneath, attic air handlers and large floor plans decide where water hides, so the walkthrough checks each one.

What the claim file holds
Ranges are typical, not a quote: the water category, square footage, material class and how fast drying started move the number most. Sudden and accidental water from a pipe, appliance or tank is often covered by a homeowner policy, while surface flooding usually needs a separate flood policy, so check your own policy.
The mitigation team builds the file an adjuster reads: a moisture map, daily psychrometric logs, timestamped photos taken before demolition, the category and class, and a line-item scope. For a closer range, run the water damage cost calculator.
How winter storm and hillside runoff cleanup is handled, step by step
Clear debris
Shovel out mud and silt.
Extract
Pull runoff from floors and pad.
Remove and treat
Soaked materials out, antimicrobial on.
Dry and log
Readings tracked until dry.
Walnut gets roughly 17 inches of rain in a typical year, and the wettest months are January and February. When the ground on the San Jose Hills is already soaked, the next storm sends runoff and mud downhill toward patios, garages and back doors.
Where the water comes from
The city sits on the slopes of the San Jose Hills, and after long rain saturated ground nearest the hills can shed water and debris toward homes. Elsewhere, heavy rain can pond at low spots in a street and storm drains can clog with leaves and debris, so water backs up toward driveways and door thresholds.
Why runoff is handled as Category 3
Outside water picks up soil, fertilizer, oil and sewage on its way in, so the IICRC S500 standard treats it as Category 3. Carpet, pad and drywall it soaked are removed rather than dried, mud and silt are shoveled and extracted, and surfaces get an EPA-registered antimicrobial before drying.
Drying after the storm passes
Once the debris is out, air movers and LGR dehumidifiers dry framing, slab and wall bottoms, with readings logged every day. If the rain also came through the roof, the roof leak water damage work runs alongside so the attic and ceilings dry at the same time.

Still dealing with it?
Runoff or mud came under the door? Stay out of moving water, cut the power if safe and call.
(888) 563-9619 Ask about runoff and flood coverageIs storm runoff inside the house dangerous?
Runoff is treated as Category 3 water because it can carry soil, chemicals and sewage. Keep children and pets away, wear boots and gloves, and leave porous materials for removal.
Does homeowners insurance cover storm flood damage?
Surface water entering from outside usually needs a flood policy, while rain through a damaged roof may fall under a homeowner policy. Check your own policy before assuming either.
Can carpet be saved after runoff gets in?
Usually not. Carpet and pad soaked by outside runoff are removed under the IICRC S500 standard. Hard flooring and framing are cleaned, treated and dried.
How long does drying take after a storm flood?
Four to seven days is common once debris and wet materials are out. Mud-filled wall cavities or a delayed start add time.
How can homes near the hills limit runoff damage?
Keep drains and gutters clear before the rainy months, check that grading slopes away from the house and keep sandbags ready for garage doors in a heavy storm.
