Flood Preparedness

Anticipated storms may bring heavy rains and flooding to Northern California this winter. Scientists say a number of factors influence the amount of precipitation that will actually fall. Napa County Office of Emergency Services (OES) wants you to be prepared for the worst-case scenario. This information can help you make informed decisions about how to be safe.

How to Prepare

  • Check your property.
  • Clear drains, rain gutters and downspouts of debris.
  • Trim trees and landscaping as needed to ensure that branches and limbs are clear of your structure and clear from overhead power lines (contact PG&E with powerline concerns).
  • Inspect your roof for any signs of damage or needed repairs. Make arrangements for the repairs before water starts to leak inside your property.
  • Stabilize slopes on your property to prevent mud and landslides.
  • Secure outdoor furniture and other loose items from causing damage during periods of heavy winds.


Use sandbags in areas known for flooding around your property.

  • Most home improvement stores have sandbags for sale.
  • Prior to a storm (generally 48 hours before a storm) and during regular business hours, sandbags are available to residents on a first-come, first-served basis.

Make Plans

  • Make an emergency plan for your family and build a disaster supply kit.
  • Remember that local phone lines may be busy during a disaster, so designate a family member to contact outside of the area.
  • Stock up on food, water and medicine so you don’t have to go out during the storms. This El Niño season is predicted to bring periods of long, back-to-back storms that may make it difficult to run your everyday errands.
  • Don’t forget about your pet’s needs. Stock up on their food and medicine too and make sure their ID tags are up to date. Download the free “Finding Rover” app.
  • Check on your neighbors to see if they need any assistance with storm preparations.
  • Review Napa County's evacuation information and 'Know your Zone'.
