Campbell County’s real estate tax rate dropped one cent; and the Board of Supervisors has adopted a budget. One cent of real estate tax translates to about $365,000 in revenue. Two supervisors yesterday expressed concerned about added expenses the county may incur due to uncertainties with the state budget and revenue sources. But ultimately it was approved along with the $127.8 million budget, which is about $1.7 million more than the current budget. It includes higher group life insurance and health insurance costs, as well as Virginia Retirement System rate increases for county and school employees.
