Which parts of San Bruno flood during winter storms?

Low areas that drain to San Bruno Creek, especially Belle Air near SFO, see the most flooding. Downhill homes in hillside neighborhoods get runoff in garages and crawl spaces.

San Bruno's flooding comes from two directions. Near the Bay, stormwater from much of the city flows to San Bruno Creek, which empties into the Bay close to SFO. When heavy rain lines up with a high tide, the creek cannot drain, and water backs up into streets and homes around 7th Avenue and SR-380. Up in the hills, Crestmoor, Rollingwood, Portola Highlands and Pacific Heights send runoff downhill fast, flooding garages, in-law units and crawl spaces on the low side of the street.

Common Types of Storm Water Damage in San Bruno, CA

Storm water damage in San Bruno, CA usually shows up in one of these ways:

• Water coming under exterior doors and garage doors
• Runoff seeping through foundation walls into crawl spaces
• Floor drains and toilets backing up when the sewer system is overloaded
• Roof and window leaks from wind-driven rain
• Flooded garages, converted garages and in-law units at ground level
• Street water entering low homes and businesses during king tides and heavy rain

Why Floodwater Is Treated Differently

Water that comes from outside is classified as Category 3, or black water. It can carry sewage, chemicals, oil from roads, animal waste and bacteria. That means flood cleanup is not just extraction and drying:

• Carpet, pad and upholstered items that touched floodwater are removed
• Drywall and insulation are cut out above the water line
• All surfaces are cleaned and disinfected
• Workers wear full protective gear
• Drying only starts once contaminated materials are out

Our Flood Damage Restoration Process

1. Rapid Response

You call (650) 822-6798 and a crew is dispatched immediately with pumps, generators if needed, and protective equipment.

2. Safety Check

Power is shut off to flooded areas, and the crew checks for structural and electrical hazards.

3. Water Removal

Submersible pumps and truck-mounted units remove standing water from rooms, garages and crawl spaces.

4. Mud and Debris Removal

Silt, mud and debris left behind by floodwater are shoveled out and hauled away.

5. Flood Cuts and Material Removal

Drywall is cut a foot or more above the water line, and wet insulation, carpet and pad are removed.

6. Cleaning and Disinfection

Framing, concrete and hard surfaces are cleaned and treated with disinfectant and antimicrobial products.

7. Structural Drying

Air movers and dehumidifiers run until moisture readings reach normal levels. See structural drying.

8. Rebuild

Drywall, insulation, flooring and finishes are replaced once everything is dry.

Atmospheric River Flooding and the Peninsula

Most of San Bruno's flooding happens between November and March, during atmospheric river flooding events that bring days of heavy rain off the Pacific. Storms like these saturate the hillsides, overwhelm storm drains, and raise creek levels at the same time. When several storms arrive back to back, the ground cannot absorb any more water, and homes that stayed dry in earlier storms suddenly take on water.

Neighborhood Flood Risks in San Bruno

Belle Air and Lomita Park

Low, flat streets near SFO and San Bruno Creek. Street flooding, garage flooding and drain backups during high tides and heavy rain.

Downtown and San Bruno Park

Older homes near San Mateo Avenue with aging storm drains and sewer laterals. Drain backups are common in big storms.

Crestmoor, Rollingwood and Portola Highlands

Hillside streets that send runoff downhill. Garages, in-law units and crawl spaces on the low side take the water. See flooded garage cleanup.

Commercial Areas

Businesses along El Camino Real, near Tanforan and around Bayhill can see roof leaks and water entering through storefronts and loading areas. See commercial water damage.

Getting Ready Before the Storm

• Clear gutters, downspouts and the storm drain in front of your home.
• Pick up sandbags early. The city has offered them behind Fire Station 51 at 555 El Camino Real.
• Move valuables off garage floors and onto shelves.
• Test your sump pump and keep a battery backup ready.
• Check that crawl space vents and foundation drains are clear.
• Know where your main water shutoff and electrical panel are.
• Sign up for local emergency alerts from San Mateo County.

Flood Insurance and Storm Claims

Standard homeowners policies usually do not cover flooding from outside water such as rising creeks or street water. That generally needs a separate flood policy. Wind-driven rain through a damaged roof, or a sewer backup with the right endorsement, may be covered under a homeowners policy. Every policy is different. The crew documents all damage with photos and moisture readings so you have what you need for any claim.

Flood Damage FAQs

Storm Damage vs Flood Damage: Why the Difference Matters

The words sound alike, but insurance companies and restoration crews treat them differently. Storm damage usually means water that got in because something broke: wind lifted shingles, a tree limb cracked the roof, or rain was driven through a damaged window. Flood damage usually means water that rose from outside, such as a creek overflowing, street water entering the garage, or groundwater coming up through the floor. Storm damage is often covered by a homeowners policy, while flood damage usually needs a separate flood policy. The cleanup also differs: rainwater through a roof may be Category 1 or 2, while rising floodwater is treated as Category 3.

What the First 24 Hours After a Flood Look Like

• Hours 0 to 2: water stops rising; stay out until it is safe and power is off in wet areas
• Hours 2 to 6: the crew arrives, pumps out standing water and removes mud
• Hours 6 to 12: contaminated carpet, pad and soaked drywall come out; surfaces are cleaned and disinfected
• Hours 12 to 24: dehumidifiers and air movers are set up and first moisture readings are logged

Getting through these steps in the first day is what keeps a flood from turning into a mold problem.

Protecting Important Papers and Valuables

In low areas that flood, keep documents, photos and valuables safe before storm season:

• Store birth certificates, passports, deeds and insurance policies in a waterproof container on an upper shelf
• Scan important papers and photos and keep digital copies
• Keep a home inventory with photos or video of rooms and belongings
• Move heirlooms and electronics out of garages and ground floors

After a flood, those records make insurance claims much easier and protect what cannot be replaced.

After the Storm: Checking for Hidden Damage

Even if water did not come inside, a big storm can leave hidden problems. Walk around the house and look for missing shingles, clogged gutters, soil washed away from the foundation and water marks on garage walls. Check the attic for damp insulation and the crawl space for standing water. Catching these early prevents slow leaks and mold from building up before the next storm arrives.
