It’s a GO For Costco News | October 26, 2022 | 0 | by Morgan McCarthy Costco got the greenlight from Eau Claire’s city council. City council members last night unanimously voted to approve the new Costco store for the city’s northeast side. The new store will be built on Black Avenue. The hope is to start work next year, and maybe have the new Costco open before the start of 2024.
