Selectmen voted to retain the town’s single property-tax rate, which is rising 65 cents to $10.36 per $1,000 of assessed value for fiscal 2013, which began July 1. Town Administrator Paul Dawson said the town is mostly residential, and that if selectmen had decided to create a higher rate for commercial and industrial property, it would have been about $15.54 per $1,000 of valuation and would “be hitting small business the hardest.” Over the past 15 years, according to the town’s website, the property tax rate has fluctuated from a high of $13.50 in 1999 to a low of $7 in 2006.
