How Albany County floods

Flash flooding from summer thunderstorms dominates the flood profile of Albany County, accounting for 21 out of 23 recorded flood events over the last 30 years alongside 2 standard flood events.

Recent occurrences illustrate these risks. In June 2023, strong thunderstorms brought heavy rainfall and an overflowing canal that flooded a nearby mobile home park in Laramie. The following month, in July 2023, a strong monsoonal moisture push produced heavy rainfall that led to flash flooding in Laramie and areas between Laramie and Cheyenne.

National Flood Insurance Program claims reflect risk across multiple zones. Properties located in Zone A should pay the most attention, as this zone recorded 7 claims with an average payout of $39,833 and an average recorded water depth of 2 inches. Additional claims occurred in Zone X with 5 claims averaging a $2,271 payout and 0 inches of average water depth, Zone X_UNSHADED with 3 claims averaging a $0 payout and 1 inch of average water depth, and Zone X_SHADED with 1 claim averaging a $0 payout and 0 inches of average water depth.

Flood insurance in Albany County

If a building in Albany 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.
