GILLETTE, Wyo. (AP) — The assessed valuation of Campbell County in northeastern Wyoming has dropped by $1.1 billion between 2016 to this year.

The county's assessed valuation, or taxable value of property, fell to $4.183 billion in 2017 put it close to the same level it reached in 2006. The county's assessed valuation has seen a steady decline since it set a record for reaching $6.2 billion in 2015.

County Assessor Troy Clements has a majority of the loss was due to a $700 million decrease in the assessed valuation in the local coal industry.

County officials say they've made several changes to the budget and full-time positions and drastically cut the budget for a capital construction project to become more efficient.
