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 Petaluma, 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 Petaluma: what we see
The Petaluma River runs through downtown, and a summary of the city's floodplain plan lists significant floods in 1982, 1983, 1986, 1995, 1996, 1998 and 2005 (Petaluma Wetlands Alliance). Projects such as Payran Reach and Denman Reach have reduced the risk (City of Petaluma), but low areas near the river and its creeks can still flood.
The local picture
Where floodwater comes from. Knowing the local water sources helps you read warnings. Petaluma is shaped by the Petaluma River, which runs through downtown, and creeks such as Capri Creek on the east side.
Low ground and runoff. Elevation and slope determine whether water arrives as a flood or as runoff. Petaluma spans the Petaluma River valley, with low ground near the river and rolling hills to the west.
Neighborhoods include the historic west side, downtown, and the east-side neighborhoods off North McDowell Boulevard. 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.
