A final vote on using $200,000 to double the number of new patrol cars for the sheriff’s office is expected at tonight’s Dickson County Commission meeting. Sheriff Jeff Bledsoe and Mayor Bob Rial have proposed taking the additional money from an unexpected surplus at the end of the last fiscal year to buy 16 patrol cars in this year’s budget. The county already planned to buy eight new cars this year but by doubling that with some of the additional funds the sheriff’s office can replace about half of its patrol fleet. Bledsoe then plans to institute a schedule of replacing eight cars each year. The county ended the 2011-12 fiscal year with an unbudgeted $1.1 million surplus and proposed to use $200,000 of that along with $90,000 already budgeted and $110,000 in drug fund money to purchase 16 new patrol cars. The plan faces a final vote at the county commission’s monthly session at 7:00 tonight in the courthouse annex in Charlotte.
