The town of Killington was chartered on July 7, 1761, by a New Hampshire grant. In 1800, it was renamed Sherburne after landholder Colonel Benjamin Sherburne. The town voted to revert to its original name of Killington on March 2, 1999; which was approved by the Vermont General Assembly and became effective July 1, 1999. The 2007 town meeting considered a proposal to impose a three-cent surcharge on every dollar of property tax revenue. The proceeds would have been used to fund a town economic development group. The surcharge was not approved by the voters. Killington was one of thirteen Vermont towns isolated by flooding caused by Hurricane Irene on August 28, 2011. Killington was cut off for 19 days.
Secession referendums
Killington's voters have twice voted to secede from Vermont and join the state of New Hampshire, to the east. The movement stems from what some residents perceive as an inequity in taxes sent to the state of Vermont, for services received. The votes are largely symbolic, as secession is highly unlikely and would require the agreement of both states' legislatures, as well as that of the U.S. Congress.
