- Wall bottoms behind baseboards
- Subfloor under thresholds and tile

Recent storm history
From late December 2022 to mid January 2023, about six storm systems, including atmospheric rivers, hit the Bay Area over roughly three weeks. In San Leandro, a section of Estudillo Canal wall also failed in the New Year's Eve storm of 2022. Storm losses are often a string of wet days, so drying is checked again after each new round.
Water from outside is not clean
Runoff carries dirt, fertilizer and sewage traces, so storm water is treated as contaminated. That changes what gets cleaned or thrown out, and it is why wet carpet pad from outdoor water rarely stays.
- Pad is usually removed
- Hard surfaces are washed and treated
- Wet insulation and drywall come out
Planning the drying
Once water is out, mats and air movers pull moisture from floors while a dehumidifier handles the air. Wall cavities are opened where readings stay high. The main storm water page covers the full process, and the San Leandro hub lists the neighborhoods served.

Is storm water treated differently from a leak?
Yes. Water from outside carries soil and bacteria, so it is handled as contaminated and cleaned more thoroughly than a supply leak.
Why do walls get wet from a door leak?
Water wicks up from the floor into baseboards and the bottom of the drywall, and insulation inside holds it, so walls can be wet well above the visible water.
Can a series of storms cause repeat damage?
Yes. In the stormy stretch from late December 2022 into January 2023, about six systems hit the Bay Area, and drying is rechecked when a new storm arrives.
Does homeowners insurance cover rain coming in?
Wind driven rain that enters through storm openings is often covered, while groundwater seepage and flood are commonly excluded. Policy wording decides.
Should I pump the water out myself?
A small amount can be mopped up, but standing water near outlets or a larger area calls for pumps and protective gear.
What is Estudillo Canal's role in local flooding?
Estudillo Canal is a flood control channel in Zone 2 of the Alameda County Flood Control and Water Conservation District. Sections of its wall failed in October 2021 and the New Year's Eve storm of 2022.
