Storm and flood damage in Santa Rosa, CA

Santa Rosa · Local guide · Updated October 18, 2026

Storm flooding brings outside water into homes from rivers, creeks, storm drains and hillside runoff. It's treated as contaminated, and it's usually excluded from standard homeowners policies. Here's how that plays out in Santa Rosa, what to do right now, and how to reach an independent, licensed local provider. Call (628) 336-1777 any time, or use the form on this page.

Storm and flood damage in Santa Rosa: what we see

In Santa Rosa, storm flooding usually means flash flooding, creek overflow and runoff rather than river flooding. The city's Rain Ready page warns that flash floods and debris flows are more likely during intense rain, especially near areas burned in 2017 and 2020, and links to a post-fire hazard assessment map.

The local picture

Where floodwater comes from. Knowing the local water sources helps you read warnings. Santa Rosa is shaped by Santa Rosa Creek, Matanzas Creek and other creeks that run through town, plus runoff from hillsides burned in 2017 and 2020.

Low ground and runoff. Elevation and slope determine whether water arrives as a flood or as runoff. Santa Rosa spans flat valley floor on the Santa Rosa Plain rising to hillside neighborhoods on the east and northeast.

Neighborhoods include downtown and the central neighborhoods, Coffey Park, Fountaingrove, Skyhawk, Bennett Valley, Rincon Valley and Roseland. Conditions vary from street to street, so a provider should look at your specific home rather than assume.

What to do right now

1. Follow SoCoAlert and official instructions, and leave early if told to.
2. Don't walk or drive through floodwater.
3. Once it's safe, turn off power to flooded areas, or have an electrician do it.
4. Photograph water levels and damage before cleanup.
5. Call your insurer (flood policy if you have one) and a restoration provider.
