Flash Flood · Aug 11, 2022. From August 11-14, thunderstorms produced gusty winds and localized flooding.
Flood · Feb 9, 2014. A series of moist weather disturbances moved across Utah during the second week of February, bringing an extended period of snowfall to northern Utah. In addition to the new snow, two avalanche fatalities occurred during this period of time.
Flood · Jun 24, 2011. Unseasonably warm temperatures were observed again at the end of June, leading to even more river flooding across Utah. Waterways that flooded significantly during this time period included Little Cottonwood Creek, the Duchesne River, and Spring Creek in Providence, Utah.
Flood · Apr 19, 2011. The combination of warmer temperatures and heavy rainfall caused flooding across many creeks and rivers across northern Utah. A few of the most impacted waterways included the Blacksmith Fork River, the Weber River, and Chalk Creek.

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Summit County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.
Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
