Storm and Water Damage Help in Santa Rosa, CA

On October 24, 2021, Santa Rosa recorded 7.83 inches of rain, the wettest single day in its records. That storm was extreme, but heavy winter rain is normal here: the city averages about 32 inches a year, falling on roughly 74 days, and the 1982-83 season topped 55 inches. Most of that water moves through Santa Rosa Creek and its tributaries, Brush, Matanzas and Piner creeks, before reaching the Laguna de Santa Rosa on the west side of town.

The Restoration Job runs a free 24/7 line at (888) 317-9980 that connects Sonoma County callers with independent restoration providers. We aren't a contractor and don't perform the work. Many providers offer emergency response, though how quickly anyone can come depends on the company and on how many homes a storm has affected.

Santa Rosa Creek, the Culvert Downtown and the Laguna

Santa Rosa Creek rises on Hood Mountain and crosses the city on its way to the Laguna de Santa Rosa, reaching it through the Santa Rosa Flood Control Channel. In the 1960s much of the creek through the core of the city was channelized, and the section between Santa Rosa Avenue and E Street still runs in a covered culvert. Restoration since then has opened up long stretches, now lined by the Prince Memorial Greenway.

The creek's lower reach is described as especially prone to flooding, and the west side drains into the broad, flat Laguna basin, where water collects slowly and leaves slowly. In heavy storms, problems near creeks and in low areas typically include:

• Street runoff entering garages and ground-floor rooms when inlets clog with leaves
• Water rising in crawl spaces as soils saturate
• Drains and lower-level plumbing backing up when sewer lines take on stormwater

Rebuilt Neighborhoods After the Tubbs Fire

Beginning the night of October 8, 2017, the Tubbs Fire destroyed about five percent of the city's homes, including most houses in Coffey Park and Fountain Grove. Many families have since rebuilt, which means fairly new homes alongside much older ones. New construction isn't immune to water problems. Fresh plumbing connections, newly installed roofs and grading around rebuilt foundations all need their first few rainy seasons to prove themselves, and an unnoticed leak at a fitting inside a new wall can do real damage before it shows.

Owners of rebuilt homes should keep their builder's plumbing and roofing information handy. If a leak points to a construction defect, documenting it carefully helps with any warranty or insurance claim.

Older Downtown Areas and Historic Homes

The 1906 earthquake largely destroyed the original downtown, so many central buildings date from the rebuilding that followed and later decades. Older districts such as Railroad Square and the Ridgway Historic District, and established neighborhoods like South Park, include houses that may have raised foundations, plaster walls and aging galvanized or cast-iron plumbing. Those homes tend to see slow drain-line leaks, crawl-space moisture and roof leaks at old flashing, and they do better with gradual, controlled drying that won't crack plaster or warp original floors.

Handling a Leak or Flood the Right Way

Stop the source, stay out of standing water if outlets or appliances are submerged, and take photos before moving things. A restoration crew will then remove water, determine what materials can be dried in place, and set dehumidifiers and air movers with daily moisture checks. Our storm damage cleanup page covers roof and wind-driven rain damage, and water damage restoration explains the full drying process.

Sonoma County's emergency office reminds residents that homeowners policies exclude flood damage and that a new flood policy typically takes up to 30 days to take effect, so buy coverage well before the rainy season rather than when a storm is forecast.

Mold Risk in Wet Sonoma County Winters

With rain on more than 70 days in a typical year and cool, damp winter air, wet materials in local homes don't dry quickly on their own. Insulation, carpet pad and the backs of cabinets can hold moisture for days and allow mold to start growing out of sight. A lingering musty smell, peeling paint or soft drywall after a storm are signs to get moisture checked. When mold is present, mold remediation removes affected materials and addresses the moisture source.
