When flood water is an emergency
Flood water carries soil, bacteria and sometimes sewage. Do not walk through it barefoot, do not touch wet electrical items and keep children and pets out. If the water is rising or touches a panel, call 911 or your utility first. Then call our 24/7 line, and a crew will be arranged. Same-day response is offered when available.
Where flood water comes from in Aliso Viejo
Aliso Viejo sits in the Aliso Creek watershed, a drainage of about 36 square miles that reaches the Pacific Ocean, and Aliso and Wood Canyons Wilderness Park borders the city. Intense winter storms can overload gutters, patio drains and lower-level doors, and the NWS summary of January 9 and 10, 2023 describes an atmospheric river that brought 3 to 6 inches of rain to Orange County foothills.
No single flood zone applies to the whole city. For any address, ask the city Public Works department, which is listed as the floodplain contact, or search the FEMA flood map for your address. A homeowners policy usually does not cover flood, and the California Department of Insurance explains that flood needs separate coverage.
Basement and lower-level flooding cleanup
Some Aliso Viejo homes have a garage, a lower level or a below-grade storage space that can take on water when a storm drain backs up or a door seal fails. These areas hold water longest because it has nowhere to drain. Pumping comes first, then removal of wet drywall, pad and stored items, and then drying with air movers and dehumidifiers.
Cabinets, stored boxes and wooden furniture wick moisture from the floor, so they should be lifted onto blocks or moved the same day. Cardboard that sat in water is thrown away. A technician measures the framing and concrete slab before deciding what can stay.

☎ (949) 670-0939Sewage backup cleanup
A sewage backup is Category 3 water. It comes from a clogged lateral, a blocked cleanout or a municipal main, and it carries bacteria. Stay out of the room, keep pets away and do not try to clean it with household products. Report spills to the OC Health Care Agency Environmental Health line at (714) 433-6000 on weekdays, and use 911 for emergencies.
The crew sets containment, pumps the liquid, removes porous materials such as carpet, pad and wet drywall, and cleans and treats hard surfaces. Items that cannot be cleaned are discarded. A plumber or the sewer district clears the blockage, and we handle the restoration afterward.
| Water type | Typical source | Handling |
|---|---|---|
| Category 2 | Storm runoff, washing machine overflow | Remove wet pad and low drywall, clean and dry the structure |
| Category 3 | Sewage backup, rising groundwater, long-standing water | Remove porous materials, contain, clean, treat and verify dry |
Category follows the ANSI/IICRC S500 standard. Time can raise the category of water that started out cleaner.
Restoration after the flood
After cleanup, the structure is dried until moisture readings are normal. Then the rebuild begins with drywall, insulation, flooring and paint. If mold appears, a separate assessment under the ANSI/IICRC S520 standard decides whether remediation is needed, which is covered on the mold remediation page. For help with the rebuild, see water damage repair.
What affects flood restoration costs
The water category, the size of the area, the depth and duration of flooding, the materials involved, the drying days and the amount of demolition all move the price. Sewage and groundwater events cost more than clean supply-line leaks because more material has to be removed and disposed of. We explain scope and price before work starts.
Insurance basics for flood loss
Flood is usually not covered by a standard homeowners policy, and the California Department of Insurance says flood coverage is separate. A sudden pipe burst or appliance failure is different and may be covered, so check your policy and ask your insurer which one applies. We keep dated photos and moisture readings for your records.
We handle floods in Aliso Viejo and the nearby cities. If you are on the coast side of the area, see Laguna Beach for local details.
Common questions
Do you handle flood damage emergencies at night or on weekends in Aliso Viejo?
Yes. The 24/7 line takes calls any hour, including weekends and holidays. Tell the dispatcher what the water is, how deep it is and whether any power or gas is involved. Same-day response is offered when available.
Does homeowners insurance cover a flood?
A standard homeowners policy usually does not cover flood, and flood coverage is bought separately. Sudden pipe or appliance leaks are different. Check your policy or ask your insurer, and ask us for photos and moisture records.
How do I find out if my address is in a flood zone?
Search the FEMA flood map for your address, or ask the City of Aliso Viejo Public Works department, which is listed as the floodplain contact for the city.
Can I clean up sewage myself?
No. Sewage is Category 3 water. Keep everyone out and call a restoration crew with protective equipment. You can also report spills to OC Health Care Agency Environmental Health.
Is a garage or lower level treated differently?
The same standards apply, but those areas often hold water longer and have concrete and stored items. We pump, remove soaked materials and dry slabs and framing before anything is rebuilt.
