Taxable property within the Town may be reappraised from time to time as may be deemed expedient by the Representative Town Meeting on recommendation of the Selectboard when advised by the Board of Listers that the State Division of Property Valuation and Review has determined that the common level of assessment has dropped below 80 percent or the coefficient of dispersion has exceeded 20 percent. In the event that a sufficient sum is not appropriated or existing in any reserve fund designated for reappraisals to defray the expense of such reappraisal, the Selectboard shall impose a special assessment on the grand list in addition to all others approved by the voters or as provided by law. (Amended 2003, No. M-6, § 2; 2011, No. M-10 (Adj. Sess.), § 2, eff. April 27, 2012.)
