Previous Disaster Events in Salt Lake County

 
 

1982-1983 Floods

After record-breaking water years of 1981 and 1982, there were massive mudslides in Big and Little Cottonwood canyons which damaged more than 300 homes throughout Salt Lake County. The county and the state declared a state of emergency (the federal government declined this declaration).  In May 1983, massive snow melt caused flooding throughout  Utah. In Salt Lake County, City Creek breached it's banks, rushing down South Temple and Thirteenth South.  State Street in Salt Lake City was formed into a river to avoid massive damage to the Salt Lake City business district.  At the end of June 1983, the majority of the disaster had ended and the recovery began.

Cottonwood Heights Flooding–2010, 2011, 2012​

2010

In June 2010, there had been a cooler than normal spring which delayed snowmelt until late May and early June.  Around June 7 & 8, there were heavy rainstorms in addition to suddenly warming temperatures.  All of this combined led to multiple areas of flooding throughout Salt Lake County, primarily in Murray and Cottonwood Heights with swollen rivers and creeks breaching banks.  Everything culminated beginning June 9 and lasting several days with the flooding.  The total cost of response to this event was around $500,000

2011

2011 brought more of the same with the spring runoff quickly rising during the timeframe of 1.5 days.  The flooding occurred throughout Cottonwood Heights, Murray and Sandy, although there were minimal effects thanks to several weeks of preplanning and prestaging of sandbags and other required items.
