How Teller County floods

Flash flooding from summer thunderstorms dominates the flood profile of Teller County, with the NOAA Storm Events Database recording 25 flash flood events over the last 30 years. These incidents are driven by heavy localized rainfall from seasonal storms. For example, a heavy storm produced flash flooding in southwest Teller County in August 2017, and high rainfall rates caused flash flooding west of Divide on US Highway 24 in August 2014.

National Flood Insurance Program records indicate historical claims across different zones with varying impacts. Zone X accounts for six claims with an average payout of $4,798 and an average recorded water depth of 8 inches. Zone A accounts for three claims with an average payout of $1,215 and an average recorded water depth of 1 inch. An additional claim is categorized as Zone UNKNOWN with a $0 payout and 0 inches of recorded water depth.

Homeowners, real estate agents, and journalists should pay the most attention to properties located in both mapped moderate-to-low risk areas and special flood hazard areas, as historical claims and flash flood events demonstrate that water accumulation occurs across multiple zones during intense summer thunderstorms.

Flood insurance in Teller County

If a building in Teller 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.
