Storm and flood damage in Fairfax, CA

Storm flooding brings outside water into homes from creeks, tides, storm drains and hillside runoff. It's treated as contaminated, and it's usually excluded from standard homeowners policies. Here's what that looks like in Fairfax, what to do, and how to get connected with an independent, licensed local provider.

Storm and flood damage in Fairfax: what we see

In Fairfax, storm flooding comes from Fairfax Creek and San Anselmo Creek rising quickly as the hills drain, plus runoff and debris on steep streets. Small older homes near the creeks are most exposed.

The local picture

Where floodwater comes from. Knowing the local water sources helps you read warnings. Fairfax is shaped by Fairfax Creek and San Anselmo Creek, which drain the surrounding hills through town.

Low ground and runoff. Elevation and slope determine whether water arrives as a flood or as runoff. Fairfax spans the head of the Ross Valley, with steep wooded hills, narrow canyons and roads that climb toward open space.

Conditions vary a lot from street to street in Fairfax, so a provider should assess your specific home.

What to do right now

  1. Follow AlertMarin 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.
