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 Sebastopol, 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 Sebastopol: what we see
The Laguna de Santa Rosa spreads over low ground on Sebastopol's east side in big storms, and the city has made sandbags available to residents during storm events (City of Sebastopol). Atascadero Creek and west county runoff add their own flooding.
The local picture
Where floodwater comes from. Knowing the local water sources helps you read warnings. Sebastopol is shaped by the Laguna de Santa Rosa and Atascadero Creek.
Low ground and runoff. Elevation and slope determine whether water arrives as a flood or as runoff. Sebastopol spans rolling west county hills that drop to the low ground of the Laguna de Santa Rosa on the east side.
Neighborhoods include downtown, neighborhoods along the Laguna, and the surrounding west county hills. Conditions vary from street to street, so a provider should look at your specific home rather than assume.
What to do right now
- Follow SoCoAlert and official instructions, and leave early if told to.
- Don't walk or drive through floodwater.
- Once it's safe, turn off power to flooded areas, or have an electrician do it.
- Photograph water levels and damage before cleanup.
- Call your insurer (flood policy if you have one) and a restoration provider.
