The Flooding Character of Snyder County

Flash flooding from heavy rainfall events is a significant concern in Snyder County, PA. Over the past 30 years, NOAA Storm Events data shows 18 flood events and 17 flash flood events, with one recorded fatality. Recent examples include flash flooding in May 2013 due to intense rainfall rates of 1-2 inches per hour in areas around Lewisburg and Selinsgrove, and flooding in March 2015, partly attributed to ice jams along Penns Creek.

National Flood Insurance Program (NFIP) claims data indicates that properties in Zone A have experienced the most claims, with an average payout of $13,537 and an average water depth of 7.3 feet. However, properties in Zone X_UNSHADED have seen the highest average payouts at $18,743, with an average water depth of 6.6 feet, suggesting that even areas outside of high-risk zones can experience substantial flood damage. Homeowners and real estate agents should pay close attention to properties located in Zone A and Zone X_UNSHADED, as well as those in proximity to waterways, given the historical frequency and impact of flooding in the county.
