First steps for storm runoff and flood cleanup in Simi Valley
- Stay out of the water
Floodwater can hide debris and contamination, and it may be electrified, so keep out until power is shut off.
- Divert what you can
Clear a drain or move sandbags only if it is safe, and keep runoff away from the door where possible.
- Protect belongings
Raise furniture, boxes and electronics to dry ground and avoid carrying wet items through clean rooms.
- Photograph everything
Record the water level on walls, the mud mark and every damaged item before cleanup changes the scene.
How storm runoff and flood cleanup is handled in Simi Valley
Storm water carries soil, yard debris and bacteria, which is why it is handled differently from a clean pipe leak. In Simi Valley the city says everyone lives in a flood zone, with some properties at low risk and others in a Special Flood Hazard Area, also called the 100-year flood zone.

The storm runoff and flood cleanup process, step by step
- 1
Remove the debris
Mud, silt and wet debris are shoveled and bagged so the floor can be reached and the water measured.
- 2
Extract the water
Pumps and extractors clear standing water from the garage, entry and rooms, working toward the lowest point.
- 3
Cut and treat
Wet drywall above the water mark and soaked pad come out, and surfaces are washed and treated with an antimicrobial.
- 4
Dry the structure
Dehumidifiers and air movers dry framing and subfloors until daily readings match the dry reference point.
Where the runoff comes from
The Arroyo Simi and its tributary channels, including Bus Canyon, Tapo Canyon Channel and the North Simi Drain, contain more than 2,300 acres of floodplain, according to a May 2013 city letter.
Ordinary heavy rain is enough to cause trouble: the city says closely grouped storms saturate the soil, and rain that continues for days or weeks can also cause flooding.
Garages and entries take the first hit, since runoff pushes in at door thresholds and low points before it reaches living areas.
What the cleanup involves
Flood water is treated as Category 3 because it crosses yards, streets and drains before it reaches the house. That is why the crew wears protective gear and bags porous materials instead of drying them.
- Mud and silt are shoveled and hauled out before extraction.
- Standing water is pumped or extracted from the garage, entry and rooms.
- Drywall is cut above the water mark, and wet pad and carpet are removed.
- Baseboards and cabinet bases are checked for silt and wicked water.
After tear-out, surfaces are washed, treated with an antimicrobial and handed to structural drying for the dehumidifier and air mover phase.
Heavy rain seasons in Simi Valley
February is the wettest month, and February 1998 brought 17.20 inches of rain during El Nino storms. A storm system that began November 14, 2025 delivered 5.57 inches, and the National Weather Service issued flood warnings for Ventura County.
Flood maps are being updated
The city is in the second year of an estimated four-year FEMA Physical Map Revision, because current maps use information from the early 1990s. The cleanup itself does not depend on any map.

Water still moving in Simi Valley?
Unsure how far the runoff reached? Describe the entry, garage and wet rooms, and the response team will explain the cleanup.
(888) 578-6508 Ask about Simi Valley flood cleanupIs flood water from a storm contaminated?
Treat it that way. Runoff crosses yards, streets and drains before reaching the house, so the crew handles it as Category 3, with protective gear and removal of porous materials.
Does everyone in Simi Valley live in a flood zone?
That is what the city says: everyone lives in a flood zone, though some properties are low risk and others sit in a Special Flood Hazard Area, also called the 100-year flood zone.
Why are the flood maps changing?
The city is in the second year of an estimated four-year FEMA remapping because current maps rely on information from the early 1990s. The crew documents damage the same way regardless of the map.
Can the crew clean a garage and a living area?
Yes. Garages and entries usually take the first hit, but the same cleanup of mud, water and wet materials extends into living areas, and water extraction handles the standing water.
When does flooding usually happen here?
The city says flooding generally occurs in the rainy season from October through April, and the region averages about 12 to 18 inches of rain a year. Closely grouped storms raise the chance.
Should I move wet furniture myself?
Lift small items onto dry ground, but leave heavy pieces and soaked upholstery for the crew, since moving them through contaminated rooms spreads mud and bacteria.
Runoff inside your Simi Valley property?
Silt and contaminated water keep soaking into drywall and pad while they sit, so cleanup works best when started early.
