CMP Estimated Impact on Property Taxes

CMP would have 11.1 miles of new power line in Whitefield at contruction cost 3.6 million per mile.  It would equal a $40,000,000 CMP capital investment added to our tax base.  Impact on property taxes would be an estimated 2.5 mil rate reduction of property taxes.  What does that mean to the property taxpayer?  It would be a $250.00 reduction of property taxes for a  $100,000 valuation.
