NAPA, Napa County — October 22, 2026. Flood preparedness begins before an atmospheric river reaches the valley. The City of Napa publishes a flood inundation map, river and creek guidance and information on where residents can get sandbags. But a review of the city’s own webpages also reveals an inconsistency that residents should resolve before driving to a pickup site.

What the city says about flood areas

Napa’s Flood Inundation Areas page describes flooding from both the Napa River and local creeks and streams. River floods can develop over hours or days; flash floods from smaller waterways can arrive with much less warning. The city’s map separates four stages of possible flood impact. These reference zones are not the same as a live evacuation map.

Why sandbag directions deserve a check

The city’s Getting & Using Sandbags page currently describes self-serve distribution on the first Saturday November through April, 8 a.m. to 4 p.m., at 720 Jackson Street, with a ten-bag household limit. A separate Floodplain Management page gives a December through March, 9 a.m. to 1 p.m. routine and cites 770 Jackson Street. These differences could reflect pages being updated at different times. California58 cannot responsibly declare one of those conflicting schedules definitive without direct confirmation from the city.

What residents should do

Before traveling, check the newest city emergency announcement or call the City of Napa Corporation Yard at 707-257-9541 (listed as voicemail-only on Saturdays). In a flood watch, the city may open additional distribution locations; use the current emergency information page rather than a calendar copied from a past winter.

Maps are for preparation, not live instructions

Flood zone maps can help people think about past river and creek behavior. A property outside a mapped area can still flood if drainage is blocked or severe rainfall overwhelms a small stream. During a live event, follow National Weather Service alerts, local street closure information and emergency direction. Never drive around a flooded-road barricade.

Prepare ahead

  1. Find your address relative to the city flood areas and nearby waterways.
  2. Review flood insurance and emergency plans separately from normal homeowners coverage.
  3. Save city emergency and sandbag information pages.
  4. Clarify conflicting sandbag schedules before relying on either one.
