The University of Vermont has concluded that property damage from flooding will exceed $5.2 billion in the next 100 years. Flood damage projections are expected in the Winooski River floodplains. Many of the state’s most populous towns are in the floodplains, including Burlington, Essex, Colchester, Williston, and Montpelier.
The University of Vermont is also developing a comprehensive map of flood risks across Vermont’s Lake Champlain Basin. The comprehensive map intends to reveal greater flood damage in more detail than any other existing model. Researchers were able to evaluate eight different levels of flood probability ranging from smaller floods that occur every 1-2 years to larger 50-, 100- and 500-year floods.
