Vermont has experienced significant flooding in recent years, including major floods in 2011, 2013, and 2017. There are a number of factors that contribute to flooding in Vermont, including:
- Geographic location: Vermont is located in the northeastern United States, where heavy rainfall and snowmelt from the Adirondack Mountains and Green Mountains can quickly overwhelm rivers and streams.
- Topography: Vermont's mountains and valleys can create localized flooding, especially when combined with heavy rain or snowmelt.
- Climate change: Climate change is leading to more extreme weather events, including heavier rainfall and more frequent heat waves. These events can contribute to flooding risk, as hotter temperatures can melt snow and ice more quickly, and heavy rainfall can overwhelm sewer systems and cause rivers and streams to overflow.
- Infrastructure: Vermont's aging infrastructure, including dams, bridges, and culverts, is often inadequate to handle heavy rainfall and snowmelt.
- Land use: Development in flood-prone areas can increase the risk of flooding, as impervious surfaces like roads and parking lots prevent water from being absorbed into the ground.
Could flooding become the norm in Vermont?
Experts warn that the risk of flooding in Vermont could increase in the future due to several factors:
- Climate change: The frequency and intensity of heavy rainfall and snowmelt events is expected to increase with climate change, which would increase the risk of flooding.
- Aging infrastructure: Vermont's aging infrastructure is in need of repairs and upgrades, and the state often lacks the financial resources to make those repairs. As infrastructure deteriorates, flooding risk will increase.
- Land use: Development in flood-prone areas continues to occur, putting people and property at risk.
To reduce the risk of flooding, Vermont needs to take steps to adapt to the changing climate. This includes updating infrastructure, planning for and regulating development in flood-prone areas, and developing a plan for responding to natural disasters.
