Yakima County commissioners agreed Tuesday to invest $1.8 million to help the city of Yakima develop the old mill site along Interstate 82.

"It is $900,000 in a grant and it is $900,000 in a loan,” explained county finance director Craig Warner. "The loan is due to be repaid by the city of Yakima by June 1 of 2017 in a lump sum."

The money will be used to help the city prepare the site for development, including engineer designs of new roads and utilities, and environmental work. Yakima County has an interest in the site being developed because it is working on an east-west corridor connecting Terrace Hights with the former mill.
