POWNAL â The Select Board discussed but didnât decide Wednesday how a $600,000 bond for the new town office project would be repaid if the proposal wins voter approval during the March 2 election. Taxing options were discussed during a public hearing, however, and those included assessing a flat charge on all real estate parcels; assessing a charge on only developed parcels, or taxing according to the assessed value and tax rate, the way other property bills are determined. A flat tax on property is the method of repayment for the bond that funded the Pownal wastewater system, which opened in 2006. Owners of developed parcels have paid a flat tax of approximately $70 per year on the sewer bond, while undeveloped parcels are assessed roughly half as much.
