[ARCHIVED] Museum Flood Area July 22 Evening Media Advisory


Museum Flood Area July 22 Evening Media Advisory

Below is a summary of today’s activities by the Coconino County Flood Control District and City of Flagstaff related to the Museum Flood Area.

Weather Forecast: The forecast for this evening has storms moving in from the east to the south of Flagstaff and are not predicted to impact the burn scar area overnight. This is a change from earlier forecast. The next round of storms that are predicted to come through will be tomorrow around 12:00 p.m. (noon). Tomorrow evening is still forecasted for heavy rain in the evening beginning around 6:00 p.m. and will be moving east to west along I-40.

Night-Time Rain Predicted:  The Coconino County Flood Control District and the City of Flagstaff are working closely with the National Weather Service (NWS). Some of the NWS models are showing a potential for heavy rainfall over the Museum burn scar tomorrow night. Nighttime flooding is extremely dangerous. Below are important measures to follow for those in the Museum Flood Area and areas prone to post-wildfire flash flooding:

  • Keep your phone nearby to receive Emergency Alerts. 
  • Know where your children are.
  • Keep your pets indoors.
  • Be prepared to shelter in place.
  • Do not park on roads where flooding has or may occur.
  • Charge your phones.
  • Have flashlights with batteries.

Sandbag Operations: 10,800 sandbags were produced today, and 6,000 sandbags were placed into the flood area. The goal is to have a stockpile of 60,000 – 75,000 sandbags in addition to meeting daily needs. Pre-filled and self-fill sandbags continue to be available to both the stations (South parking lot of Coconino High School at 2801 N Izabel and Coconino County Health and Human Services at 2625 King Street). 

Flood Mitigation Site Assessments: Seven assessments were completed today. There is currently a backlog so please be patient as we respond to requests. Please request a site assessment by contacting the Call Center at 928-679-8525 if you are experiencing one or more of the following:

  • Floodwater has overtopped your sandbags or other mitigation measures
  • The flow of floodwater was not mitigated by your current sandbag walls
  • Mitigation employed by adjacent property owners is impacting your home


  • Today the priority was enhancing the mitigation at the Arroyo Seco inlet. This work will involve 50 interlocking concrete blocks and 4,000 sandbags. Work on this effort will continue tomorrow. 
  • The other priority was placing additional sandbags at the barriers at the end of Paradise Drive, which were needed given erosion that was taking place under the barriers. Approximately 900 sandbags were placed. 
  • Cedar Slip Lane (West Street/Linda Vista) engineering improvement for storage and drainage conveyance has been completed. 

Call Center: 44 calls yesterday with a total from the beginning of the flooding is 385. 

Mental Health: This is a stressful situation. Don’t hesitate to ask for help if the stress is getting to you or someone you know. Talking to a friend or a counselor can help. If you have any questions, then please contact the Guidance Center at 928-527-1899; Terros Health, 1-877-756-4090; Southwest Behavioral & Health resources, 928-779-4550; or other private Behavioral Health provider.

Public Infrastructure Assessment: The City of Flagstaff is conducting ongoing assessments of the public infrastructure impacted by the flooding and have identified 110 sites. The damage to these sites has an estimated damage (plus labor and equipment) of $3.1 million. Of the number above inside the Museum Flood Area, there are 14 sites and an estimated damage (plus labor and equipment) of $419,000.

National Guard: The National Guard Engineering and Operations team were deployed to the field today where they cleaned out drainages and channels ahead of additional rain events. 

Volunteers Needed: United Way of Northern Arizona is planning a Neighbor Helping Neighbor Event to help support flood mitigation this Saturday, July 24. We need more volunteers to make sandbags, place sandbags at residences, and to assist with clean up. Please sign up at or call 928-773-9813.
