Flood Depth and Evacuation

New Flood Maps

The County of Sacramento and the City of Sacramento have prepared various detailed maps showing hypothetical levee breaks, inundation levels and the time it would take for waters to rise in affected neighborhoods, and rescue and evacuation zones. The maps come in pairs.

  1. FLOOD DEPTH MAPS: Show where the water would flow over time and how deep it would get given the hypothetical flooding scenario.

  2. RESCUE AND EVACUATION ROUTE MAPS: Show rescue areas, evacuation areas, and potential evacuation routes.
    • Rescue areas [red] indicate places where water has the potential to reach a depth of at least one foot after two hours from the time of a levee failure. People would not be able to drive out and likely would be stranded and require rescue.

    • Evacuation areas [yellow] indicate places, depending on where the levee breech occurs, that could fill from 1 to 26 feet of water within 10 days, giving most people time to get out safely. Flood depth details are specified on each map.

    • Potential evacuation routes shows which evacuation routes would become inundated over time.  During intense or prolonged storms, it is very important to listen to emergency officials and comply with the instructions they give you. If the power goes out, be prepared to hear such emergency instructions with a battery operated radio, and have spare batteries on hand.

Voluntary evacuation

If a voluntary evacuation is announced, it means a levee failure is possible. People should take heed and leave while roads are still dry.
Generally, you will not need to drive for hours to be safe if a levee fails. You only need to get to high ground. Plan ahead and make arrangements with family or friends whose homes are on high ground. Good areas to aim for: 
Carmichael, Citrus Heights, Cities along the I-80 corridor such as Rocklin and Auburn, Folsom and Davis. In general, going north on I-5 or Highway 99 is not advised because of low spots and the fact that several rivers and tributaries are draining southward in that vicinity. Heading south on Highway 99 is also uncertain because it can flood.
Do not assume that the evacuation routes shown on the maps will necessarily be your way out in a flood. Localized flooding, traffic accidents, and different flooding scenarios will all affect whether roads will be open. Emergency officials will monitor roads and let the public know through radio stations and other media if alternate routes should be taken.
Emergency officials will open shelters as required. Shelter locations depend on where a levee break occurs and the associated flooding scenario.
