A sign that the local economy is picking up, sales at Colony Square Mall in Zanesville have increased 20 percent. Those figures, from February, are a total of all mall shop sales. Some of the increase is attributed to the addition of Dunham’s and Old Navy. Several veteran retailers had impressive increases: Zanesville Chiropractic, Shoe Sensation and Vitamin World are among those stores. Not only have sales increased, but the number of shoppers have gone up. The food court is getting a new establishment, the famous Wok that features Asian style food will open soon. Finding a new tenant to fill the vacancy left by Lazarus is still in the works.
