San Timoteo Creek and the flood history homeowners should know
San Timoteo Creek flows through Loma Linda, and in 1969 it flooded about two-thirds of the city. It flooded again in 2010. Those events are part of why the city treats drainage seriously, and why a homeowner who sees water rising in a yard should call right away. If you are close to the creek corridor, pull up your address on FEMA's flood map and ask your insurer about flood coverage.
Flooding is not the only way water gets in here. A dense neighborhood means shared walls, shared drainage and many older fixtures. Our flood damage restoration page explains how floodwater cleanup differs from a burst pipe.
When water is spreading in Loma Linda
In a dense area, spreading water can reach more rooms faster. A leak in an upstairs unit can come through a ceiling and into the apartment below, and a hose failure in a laundry closet can soak carpet in several rooms. Call the emergency line the moment you see water moving, and shut the supply off at the nearest fixture.
For wet carpet, wall bases and drywall, emergency water removal is the first step, followed by structural drying with air movers and dehumidifiers. A crew will take moisture readings so you know what is wet and what is not.
Loma Linda at a glance for restoration calls
Medical campus neighbors
Loma Linda University Medical Center, Loma Linda University and Loma Linda Academy bring staff and students who rent nearby. Emergency dispatch is available around the clock.
South Hills open space
The South Hills cover the southern third of the city, and slopes above homes can shed water quickly in a storm.
Dense blocks
Closely spaced homes mean water can affect neighbors. Tell us if the leak is shared.
If Water Is Still Spreading
Shut off the nearest supply
Close the fixture valve or the main. In multi-unit buildings, tell the landlord or HOA right away so the shared supply can be closed.
Power only if safe
Shut off power to soaked rooms only if the panel can be reached without wading. A light fixture dripping water is a reason to step away and call 911 or the power utility.
Lift belongings off the floor
Move electronics, bedding and papers onto dry surfaces. Pull rugs and light furniture away from the wet area.
Keep everyone out of floodwater
Creek runoff, toilet overflow and drain backups are contaminated. Keep people and pets away and wait for the crew.

Neighborhood notes from Mound City to Bryn Mawr
The city was once called Mound City, and its eastern half was the community of Bryn Mawr, which is why you will find a range of building ages across a short drive. Older homes may have older plumbing, and newer ones may have newer failure points. We check both.
Next door, Redlands is just east, with its own historic homes and permit center. If your address sits near that border, read that page too.
Water utility and permits in Loma Linda
Check your water bill to confirm your water provider, and keep its number for main shutoff questions. For permits, ask the City of Loma Linda Community Development Department whether your repair needs one before the rebuild starts.
ZIP codes in the Loma Linda service area
Loma Linda is served under ZIP 92354, where most addresses fall, and ZIP 92350, a very small ZIP with few residents. We cover both, from the blocks near the medical campus to the streets below the South Hills.
Loma Linda on the map
A standard worth naming
Dense Loma Linda blocks mean a leak can reach a neighbor quickly. ANSI/IICRC S500 gives the reference for classifying and drying water, so ask whether the crew works to it.
What to do while you wait for the crew
- Close the nearest fixture valve or the main water valve.
- Move valuables and electronics to a dry room.
- Warn any neighbor whose wall or ceiling you share.
- Keep people and pets out of any water that may be contaminated.
- Photograph the damage before anything is moved.
