Scientist Says Storm that Caused Flooding near Calgary in June, 2013 Almost Identical to Colorado Flood Storm

The problem with traditional methods of calculating the 100 year or 500 year flood is that it only looks at past historical occurrences of rainfall at a single location. The reality is that the meteorological conditions which produce floods like last September's in Boulder happen every 5 to 15 years somewhere along the Front Range. This study shows that the same conditions develop on the east side of the Rockies all the way up to northern Canada - News link . The exact location of these extreme rainfall events in Colorado depends on unique, localized conditions developing which are impossible to forecast at a specific location.  100-year flood zones along the Front Range should be based on an event of 14" of rain in 6 hours. This will never be accepted by developers and zoning officials because when you throw in the landslide potential along creeks in the mountains from these extreme rainfall events, the cost for a lot of real estate and infrastructure development will be prohibitive.

As the state climatologist points out this is a record for established, long term official rain gauges at 11.85". Many of Colorado's most severe storms like, the 1965 flood and the Big Thompson Canyon flood in 1976 had localized rainfall of 14 inches in 4 hours. The highest 24-hour rainfall estimated in Colorado was near Bonny Reservoir during the 1965 floods at 24".
