Author: Andrea Flores Updated: 10:00 AM CST March 10, 2021 DAVENPORT, Iowa — The social media campaign 'Bring Trader Joe's to the Quad Cities' is growing, and Davenport could soon be the national grocer's third Iowa location. A new building has been proposed to the grocery company. It's in the same plaza, Elmore Marketplace, as the first proposal in 2020. This time around, the renderings show a stand-alone store instead of one in the plaza's strip mall.
