Water intrusion on the Orange County coast, Seal Beach to San Clemente

Water in the house? L3 Energy Construction finds the source and repairs it: roof, window, deck and stucco leaks, damp slab floors, drainage, mold and emergency dry-out. We find every path the water took, document it for your insurer and the City, and close it. On the Orange County coast we work at the house in Seal Beach, Huntington Beach, Newport Beach, Corona del Mar, Laguna Beach, Laguna Niguel, Dana Point and Capistrano Beach and San Clemente.

The Orange County coast in the siege log

Capistrano Beach, Beach Road

First red tag. A deck destroyed, and coastal erosion undermined the slab foundation beneath it.

ABC7 · NTD
Laguna Beach, Ocean Way and Lagunita

Local emergency. Six oceanfront homes yellow-tagged with compromised seawalls.

NTD · AccuWeather
Capistrano Beach

Ten homes red-tagged, seven yellow-tagged. Seawalls failed, patios went into the ocean.

ABC7 · CBS Los Angeles
San Clemente and Newport Beach

San Clemente puts its sand deficit at 2 to 4 million cubic yards and sends Measure M, a 1% sales tax for sand and fire protection, to November's ballot. Newport Beach brings its replenishment forward: about 100,000 cubic yards of Santa Ana River sand to West Newport later this month.

Voice of OC
Newport Beach, Balboa Peninsula

Local emergency. The morning high tide came in 20 inches above the prediction, which the city's utilities director called record-breaking; 15 to 20 blocks flooded, vehicles stranded, water at front doors.

ABC7
Capistrano Beach, Beach Road

Another home went into the surf; seven red-tagged and thirteen yellow-tagged after Rachel. The houses sit on slabs on sand, and the sand is going.

ABC7
Newport Beach

Local emergency ahead of the Oct 26–28 king tides, with ocean levels running 18 to 22 inches above predicted tides. The council approved the contract for about 100,000 cubic yards of Santa Ana River sand between 36th and 62nd streets.

Laguna Beach, El Morro

Caltrans filed an emergency notice for the Crystal Cove Coastal Access Preservation Project: temporary slope and roadway stabilization and wave-energy-dispersing devices on Coast Highway near Morro Ridge Road, under the Sep 21 state emergency. One southbound lane has been closed since the bluff cracked on Oct 13, and the beach below is closed.

CEQAnet, Notice of Exemption 2026100640, Oct 19 · Patch Laguna Beach, Oct 13 · Surfer, Oct 20
San Clemente, rail corridor

Metrolink suspended Orange County Line service between Laguna Niguel/Mission Viejo and Oceanside for Oct 26–30, ahead of the king tides on the beachfront tracks at San Clemente; trains run only between Los Angeles Union Station and Laguna Niguel/Mission Viejo, with no replacement buses. In September high tides and waves overtopped the same tracks and stopped Metrolink, Amtrak and freight service.

Questions from the Orange County coast

Water came up through the floor, not through the door. What is that?

Groundwater under the slab, pushed up by a sea that is higher than the tide table. Concrete is porous, and the push is about 64 pounds per square foot for every foot of seawater above the underside of the slab. A moisture survey finds where it is coming through; a drain and sump under or around the slab take the pressure off. It is not a plumbing leak unless the meter moves with every tap closed.

Should I dry out a flooded room first, or document it first?

Do both the same day, in that order. Stop the water if it is safe, photograph everything and take moisture readings, then start drying. Most insurance policies expect you to limit the damage, and the adjuster will want proof of what was wet. L3 records the damage and runs the dry-out in one visit.

Does L3 deal with the street flooding?

No. The street, the storm drains and the tide valves are the City's. We deal with what the water did once it reached the lot: under the slab, in the walls, in the garage, and the mold that follows.

Look no further and pick up the phone!

One licensed contractor answers, finds the source, makes the repair and writes the report. Not a call center that passes your job to whoever is nearby.

No photograph of the home leaves the file without written consent. We work through the estate manager, the architect or the family office when that is how the house is run.
