Flood Warning and Awareness

  • Streets, streams and low water crossings can flood quickly! A car can float in as little as a foot of water. Do not attempt to walk or drive across flooded areas. Respect all traffic barricades.
  • Call 911 to report a flooding emergency.
  • For street or right-of-way flooding concerns, please call Public Works 213-2100.
  • If you have private property flooding concerns, the Stormwater Management Section will investigate and may be able to help. Please contact Christopher Palmer at 213-2474.
  • Please do not leave trash cans, trash, or debris in any area subject to flooding. Items will float in floodwaters and clog storm drains and stream channels.
  • Sandbags can be obtained on Aztec Street near Frances Short Pond. The sandbag filling area is not manned and residents will need to bring shovels to fill sandbags if there are not pre-made bags available.
  • Contact your property insurance agent to see if a flood insurance policy would help you. Even if you’re not in the mapped floodplain, you may be subject to flooding from local drainage. Go to FEMA’s flood insurance page at www.fema.gov/business/nfip to learn more.
  • Talk to us about protecting your house or business. There are ways to modify your building to minimize flood damage.
  • The City of Flagstaff operates a small network of radio-telemetered gauges that transmit rainfall and stream flow information in real-time (as it occurs). If you would like to see this information for the various locations in the City, plus the rain gauges in the Schultz burn area, go to: Rainfall and Stream Gauge Data. This network can send emergency alerts via text messaging and/or email for heavy rainfall. If you would like to receive these alerts, please send your request with your email address and/or cell phone number to Jim Janecek at jjanecek@flagstaffaz.gov.
  • To view forecasts, watches, and warnings issued by the National Weather Service for Northern Arizona, go to: www.wrh.noaa.gov/fgz/.”
