ADAMS TWP — Property owners will not see a tax increase in 2013, just as they haven’t in more than two decades. Three of the five supervisors on Wednesday morning passed the township’s 2013 budget without a millage increase. Supervisors chairman Donald Aiken said the last tax increase in the growing township was in 1989. The $8.5 million budget is partially supported by 3.75 mills. One mill is equal to $1 for every $1,000 of a property’s assessed valuation. Taxes will bring in almost $4.3 million in 2013, which is up $400,000 over the current year’s $6 million budget, which saw $3.9 million in tax revenue. Another major revenue source is the charge for services at $394,000. A carryover from this year’s general fund will provide $2.2 million in 2013. Regarding expenses, the public works line item will increase $200,000 from $2.9 million this year to $3.1 million in 2013. Public safety will increase $100,000 in 2013, to $1.7 million.
