What is the County’s fixed asset policy?

Capital assets, which include property, plant, equipment, and infrastructure assets (e.g., roads, bridges, sidewalks, and similar items), are reported in the applicable governmental or business-type activities columns in the government-wide financial statements. Construction in progress (CIP) projects are added as a fixed asset at the time they are in service.  The government defines capital assets as assets costing more than $10,000 and with an estimated useful life in excess of one year. Such assets are recorded at historical cost or estimated historical cost if purchased or constructed. Donated and seized capital assets are recorded at estimated fair market value at the date of donation.

The costs of normal maintenance and repairs that do not add to the value of the asset or materially extend asset lives are not capitalized. Improvements are capitalized and depreciated over the remaining useful lives of the related fixed assets, as applicable. Interest incurred during the construction phase of capital assets of business-type activities is included as part of the capitalized value of the assets constructed.

Capital assets of the primary government, as well as the component units, are depreciated using the straight-line method over the estimated useful lives.


What are the millage rates for the General Fund, Fire Fund and Debt Service Fund?

The Board of Commissioners reduced the millage rate (the measure used to assess property taxes) for 10 consecutive years from 1993 to 2002. The overall millage rate remained the same from 2002 to 2005 at 9.72 mills. The Board of Commissioners reduced the millage rate in 2006.

The General Fund was reduced by .03 mills to 6.82 mills; the Fire Fund was reduced by .09 mills to 2.56 mills; and the rate for the Debt Service Fund remained at .22 mills for a total of 9.60 mills.

In 2011 the Board of Commissioners raised the millage rate temporarily from 9.60 to 11.11 to adjust with the ever declining property tax rates. In 2014 the Board of Commissioners voted to lower the millage rate to 10.91.
