September Snow Storm - by the Numbers

Well, it has been a week since the devastating snow storm that cause so much damage to our city's trees and private property.  Here is a short rundown of some of the numbers related to the storm and the damage it caused.



  • 28.2 - centimetres of snow as registered at the Calgary airport.
  • 130 - years.  This was the most snow in September before the equinox in 130 years.  Because it came before a killng frost, the trees still had their leaves and the snow accumulated on the leaves creating more weight than the branches could withstand.
  • 74,000 - Enmax customeres were without power for at least some period of time.  Some 2,000 were without power for several days.  All power was restored in less than a week.
  • 7,000 - calls to 911.  The highest single day number, ever.
  • 47,000 - calls to 311 with 6,500 of them "tree emergencies"
  • Over 100 - traffic signals without power and 3 LRT stations.  All restored to power within 24 hours.
  • 5,000,000 - kilograms (11,000,000 pounds) of tree debris collected at city landfills by the 17th of the month.  That's enough to fill McMahon Stadium 3 meters (10 feet) deep.
  • 33 - leaf a debris drop off locations opened by the City where people can take their tree branches.  Click HERE for a list of the locations.
  • 3 - tips for looking after your trees and a short video on how to safely trim the broken branches can be found HERE.
  • 500,000 - is the estimated number of trees in the City of Calgary inventory.  Each of them will require inspection and possibly pruning.  Some will need to be removed.

These numbers were taken from an infographic from the City of Calgary web site.  It can be found HERE.


It has been quite a summer.  Between the hail storms (Airdrie) and north and now this snow storm, I think it is time we had a break from all these "weather events".
