How storm runoff flooding cleanup is handled
Treated as Category 3
The mitigation team handles runoff as contaminated water, with protective gear and containment where needed.
Porous materials removed
Carpet, pad and drywall touched by floodwater are cut out and bagged, because porous materials touched by Category 3 water get removed, not dried.
Cleaned, treated, then dried
Silt is cleaned off, an EPA-registered antimicrobial is applied, and the drying team runs equipment until readings meet the goal.

How storm water gets into San Marcos homes
The city sits in a valley between the Merriam Mountains, Double Peak and the hills around San Elijo, with San Marcos Creek running through the Creek District. Most of the year it is dry, then a few storms drop a lot of rain fast. Graded hillside lots shed that water toward houses, clogged area drains back up, and low crossings along the creek have historically closed during heavy storms.
- Runoff coming down a slope and under a slider or garage door
- Area drains and yard drains overwhelmed by leaves and silt
- Water pooling against stucco and wicking into bottom plates
- Low spots near the creek taking on surface water
Why runoff is handled differently from a pipe leak
Water from a supply line starts clean. Storm water has crossed yards, streets and soil, so it is Category 3 from the start. The response team wears protective gear, removes porous materials to above the water line, cleans surfaces, then applies an EPA-registered antimicrobial before drying. Skipping those steps leaves odor and contamination behind the new drywall.
Insurance and flood coverage
Standard homeowners policies usually exclude rising surface water, which is covered by flood insurance instead. The claim file still matters: photos of the water line, a moisture map and daily readings. FEMA flood insurance information explains how flood policies work, and the National Weather Service San Diego office posts storm and flood warnings for North County. If the storm also found a weak spot overhead, see roof leak water damage.

Floodwater carries soil and contamination, so what it touched is removed before anything is dried.
(888) 450-9281Is storm runoff really contaminated?
Yes. Surface water crosses yards, streets and soil and can carry sewage, fertilizer and fuel. The IICRC classifies it as Category 3, so it is handled with protective gear and porous materials are removed.
What is a flood cut?
A horizontal cut in drywall above the highest water line, usually 12 to 24 inches up or higher. It removes contaminated material and lets the wall cavity dry.
Can my carpet be cleaned after a flood?
Carpet and pad soaked by floodwater are normally removed and discarded. Hard surfaces like tile and sealed concrete are cleaned and disinfected.
Does homeowners insurance cover runoff?
Most homeowners policies exclude rising surface water; flood insurance covers it. Water that entered through a storm-damaged roof may be treated differently. Coverage depends on your policy, so it is worth checking with your own insurer.
How long does flood drying take?
After removal and cleaning, drying usually takes three to seven days, depending on how deep the water was and what materials stayed in place.
How can I reduce runoff next winter?
Clear area drains before the first storm, keep soil and mulch below the stucco weep screed, check that slopes drain away from the house and add a threshold or barrier at low doors.
