Corona was laid out in 1886 as a citrus colony inside a one-mile circle, and Grand Boulevard still traces that circle around the old downtown. The city grew from 37,000 people in 1980 to more than 150,000 today, and almost all of that growth is 1980s through 2000s slab tract housing climbing the hills south of the 91 toward Cleveland National Forest and filling the flats north toward the Santa Ana River. Inside the circle, the houses are 1910s to 1950s bungalows and ranch homes, many still on their original plumbing.
Water comes at Corona from three sides. Temescal Wash runs the length of the city on its way to the river, the canyons south of town send debris flows down onto the hillside tracts in a heavy storm, and Prado Dam, finished in 1941 at the west end of the city, holds the Santa Ana River back from Orange County and backs it up toward Corona's north side instead. The January 2023 and February 2024 storms put water in both.
This site routes Corona homeowners to an independent local water damage provider by phone. The provider sets the scope from readings inside the house.
A slab leak in a 1960s house inside the Grand Boulevard circle is a leak detection call first, with slab leak water damage drying after the plumber leaves. A hillside tract house in Sierra del Oro or South Corona that took mud and water off the slope in a storm is storm flood cleanup, and the crew treats it as contaminated.
The City of Corona operates its own water utility and its own Building Division, so both the meter shutoff and the rebuild permit come from the same place. Tell the crew whether the house is inside the Grand Boulevard circle or up on the hillside, because the two drain in opposite directions.

Standing water pulled off slab-floor tile, laminate, and carpet in a Riverside house, then the first meter readings to see how far it ran.
Air movers and dehumidifiers run until slab-side drywall, cabinets, and flooring hit their dry target, even on a cool, damp January week.
A warm tile, a spinning meter, or a soft wall traced to a pitted copper line under the slab or inside a wall before anyone cuts concrete.
Carpet, laminate, and the bottom of the walls soaked by a line that failed under the slab, dried out and documented once the plumber has it stopped.
Muddy street runoff and Santa Ana River bottom water pulled out of a garage or ground floor after an atmospheric river, with contaminated materials removed.
A tank that let go in a garage, side-yard closet, or hall cabinet and the drywall and flooring it soaked on the way across the slab.
A stained, sagging, or dripping ceiling under a second-floor bath, a roof-mounted swamp cooler, or an attic air handler, dried and opened only where wet.
Wet attic insulation, ceilings, and walls dried out after Santa Ana winds lifted tile or a winter storm found the valley flashing.
