Flood Safety | Mesa County

Before the flood

When Moving to a new area, check with the local floodplain manager to see if you are in an area susceptible to flooding.
Keep a stock of food which requires little cooking and no refrigeration. Regular gas and electric service may be disrupted.
Keep a portable radio, batteries, emergency cooking equipment, and flashlights in working order with additional batteries.
Keep first aid supplies and any medicines needed by members of your family on hand.
Keep your automobile fueled. If electric power is cut off, gasoline stations may not be able to operate pumps for several days.
If you live in an area subject to flooding, keep materials like sandbags, plywood, plastic sheeting, and lumber handy for emergency levee construction.
Store drinking water in closed, clean containers. Water service may be interrupted.
If flooding is likely and time permits, move essential items and furniture to upper floors of your house. Disconnect any electrical appliances that can't be moved - but don't touch them if you are wet or standing in water.

If you are warned to evacuate your home and move to another location temporarily, there are certain things to remember to do.

Follow the Instructions and Advice of Your Local Government. If you are told to evacuate, do so promptly.
If you are instructed to go to a certain location, go there - DON'T go anywhere else.
If certain travel routes are specified or recommended, use those routes rather than trying to find short cuts of your own.
If you are advised to shut off your water, gas, or electric service before leaving home, do so.
Also, find out on the radio where emergency housing and mass feeding stations are located, in case you need to use them.
Keep tuned to your radio or television station for advice and instructions from local government on where to obtain medical care, where to get assistance for such necessities as housing, clothing, and food, and how to help yourself and the community to recover.
