First steps for storm and street flooding cleanup
Stay out of the water
Keep everyone out of standing storm water and switch off power to wet areas.
Photograph the water marks
Record the high water mark on walls, the debris and any damaged belongings before cleanup begins.
Remove and extract
Mud, debris and standing water go first, followed by soaked carpet, pad and low drywall.
Clean, treat and dry
Surfaces are cleaned and treated before dehumidifiers and air movers start, since drying dirty materials locks the contamination in.
How storm and street flooding cleanup is handled
In November 2025, the city's fire department staffed an extra pump vehicle, surveyed the major washes and helped move sandbags to the Stoneman building, while flash flood warnings covered Los Angeles County. Those steps help outside; once water gets inside a house, cleanup is a separate job.
Rapid local response
Active water is treated as urgent at any hour, so the extraction crew starts while the water is still on the surface.
IICRC S500 drying standard
Moisture mapping comes first, then extraction, air movers and LGR dehumidifiers sized to the class of loss.
Claim-ready documentation
The mitigation team keeps a moisture map, daily psychrometric logs and timestamped photos for the adjuster.
Valley water know-how
Slab floors, copper under concrete, hard water and storm runoff with nowhere to drain shape each drying plan.

Storm and Street Flooding Cleanup, step by step
- 1
Assess and protect
Crews check for power hazards, suit up and map how high the water rose in each room.
- 2
Extract and clear
Pumps and extractors take out the water, then crews clear mud and debris.
- 3
Cut, clean and treat
Contaminated materials are bagged out, framing is cleaned and every remaining surface is treated.
- 4
Dry and document
Dehumidifiers run until readings normalize, and a final report lists what was removed.
Why storm water is handled as contaminated
Street and yard runoff picks up soil, fertilizer, pet waste and whatever else sits on the ground. That puts the water in Category 3, so carpet, pad and low drywall that soaked are removed rather than dried, and hard surfaces are cleaned and treated before drying begins. Standing storm water also leaves silt behind, which has to be cleaned from floors and cavities.
What the cleanup removes
The scope follows how high the water rose and what it touched. Anything touched by contaminated water is photographed and listed before it goes, so the claim shows what was lost.
- Mud and debris carried in with the water
- Carpet, pad and tack strip
- Baseboards and drywall cut above the water mark
- Soaked insulation and cabinet toe kicks
Drainage projects and what they mean at home
Design work continues on a storm drain culvert at Lacy Park meant to improve drainage during rain events, and the city does not expect construction before fiscal year 2026/27. Trash capture devices went into 39 catch basins in late 2024. Neither project dries a wet room, so structural drying and extraction still decide the outcome indoors. Houses here mostly date from 1920 to 1950, so older flooring and framing get checked closely after any soaking.

Storm and Street Flooding Cleanup: common questions
Is storm flooding covered by homeowner insurance?
Often not. Standard homeowner policies commonly exclude flood, which is a separate policy, so the adjuster decides under the specific wording. Photos and logs help whichever policy applies.
Why is storm water treated as contaminated?
It crosses yards, streets and drains before it enters, so it carries soil, bacteria and chemicals. That is why porous materials come out and hard surfaces are cleaned and treated.
Can sandbags keep water out of the house?
They help divert shallow water at a door. The city's Parks and Public Works moved sand and sandbags to the Stoneman building for public use during the November 2025 storms, and crews handle whatever still gets in.
Is the Lacy Park storm drain culvert finished?
No. Planning stands at the design stage, and construction is not expected before fiscal year 2026/27. Until work is done, a wet house depends on cleanup and drying, not on drainage plans.
What should I do about carpet after a storm leak?
Do not try to save it. Contaminated carpet and pad are removed, and the floor underneath is cleaned, treated and dried before any new flooring goes down.
Does the cleanup include the garage?
Yes. A garage is often the first space water reaches, so it is extracted, cleaned and dried along with living areas, and stored items that soaked are photographed for the claim.
Clean and dry what the storm soaked
A crew pumps out the water, removes contaminated materials, cleans and treats what remains and dries the structure with records for the claim.
