Flood · Feb 24, 2023. During the late evening hours on February 24, a skier triggered avalanche occurred and deposited snow in Flat Creek.
Flood · Mar 23, 2018. A combination of rain and snow melt brought localized flooding to northern portions of the Jackson Valley. Several side roads were flooded and a home had basement flooding from the flood water.
Flash Flood · Aug 13, 2014. A slow-moving thunderstorm developed over the Teton Range and produced heavy rain along an axis parallel to and over Paintbrush Canyon. Rainfall amounts of one-half inch to one inch fell in 20 to 30 minutes in the steep-sided canyon. A large mudslide occurred as a result, washing out large sections of a popular trail.
Flood · Dec 11, 2011. An ice jam on Flat Creek in the southwest part of Jackson caused localized flooding of structures in two areas. The creek was flooded from the Snow King Avenue bridge to High School Road. Several homes had basement and garage flooding near Crabtree Lane and Shelby Lane. Also affected was an automotive repair shop on Berger Lane.

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 Teton 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.
