The City of Tempe encourages residents to be prepared for potential flooding. In the case of severe weather, this page will be updated with tips and information. If you've experienced storm damage, please report it to Tempe 311 by calling 480-350-4311, emailing or visiting     

Storm Preparedness Checklist
Are you ready for the storm? Read this to know what to do before, during and after storms. 

The City of Tempe has sand and bags available at two locations throughout monsoon season, which begins on June 15 and ends Sept. 30. The bags can be picked up 24 hours a day, seven days a week. Prior to a major storm event, bags are available on a first come, first served basis. Be prepared by picking them up before a storm is headed our way. The two locations are:  

  • North Tempe, access drive north of Rio Salado Parkway & Hardy Drive (near free compost)
  • Benedict Sports Complex, 490 W. Guadalupe Road (northwest corner of Guadalupe and Kyrene roads) – east side of parking lot

Keep storm drains clean of debris 

The flooding of streets, sidewalks and homes can be much worse if the city's storm drains are blocked by debris. You can help prevent that by disposing your yard waste in trash receptacles. If you notice excessive amounts of debris near a storm drain, report it to Tempe 311 at 480-350-4311. Click here for more stormwater tips.

Flash Flood Safety

  • Flash floods are the #1 thunderstorm-related killer
  • Most flash flood deaths occur in vehicles
  • Moving water 1-2 feet deep will carry away most vehicles
  • Keep children away from creeks and washes when heavy rain is in the area
  • Be especially careful at night when water depth and road conditions are harder to see

Lightning Safety

  • No place outside is safe from lightning during a thunderstorm
  • Lightning can strike up to 10 miles away from a storm
  • If you hear thunder, lightning is close enough to strike you
  • Move inside a strong building or an enclosed hardtop vehicle
  • Avoid contacting inside wiring and plumbing during a thunderstorm; this includes appliances and corded phones
  • Stay in shelter for 30 minutes after the last thunder
  • If someone is struck by lightning, call 9-1-1 for help immediately


If you've experienced dangerous storm activity, please call 9-1-1 if it is an emergency, such as a downed power line or an injury. You may call the Tempe Police non-emergency number if it is not an emergency at 480 350-8311 anytime or call Tempe 3-1-1 at 480 350-4311 during business hours. 

Need help cleaning up? Call one of the city's pre-approved landscaping companies for professional assistance. Visit the Tempe Landscape Referral page for details.


Please report flooding that occurs in city streets and parks. The city cannot respond to flooding in residents' homes.  


Please report storm debris that is blocking intersections, neighborhood streets or trees that have fallen at city parks. Important note: the City cannot respond to debris that has fallen on a resident's property. Residents have a few options for debris cleanup: 

1.) Chop up the debris and follow the Bulk Trash Collection guidelines and timelines for free collection. Please keep the debris in your yard until it is time for your bulk trash collection. 

2.) Chop up the debris and contact a landscaper for cleanup if you require a more immediate response. 

3.) In the event of a severe storm, check the city's News section and the top of this page for instructions from city staff.
