Saturday is the fourth anniversary of the murder of George Floyd by a Minneapolis police officer. The civil unrest that followed his death in 2020 left its mark on the Twin Cities, with fire and other damage along parts of University Avenue, West Broadway and Lake Street. The damage, which the state priced at $500 million, was an added challenge for business owners who were already muddling through the strangeness of a new global pandemic.Each day this week on Minnesota Now, we’re looking at a different impact of Floyd’s murder on Minnesotans. We’re zooming in on Lake Street with Allison Sharkey, executive director of Lake Street Council and Alicia Belton, one of three long-term owners who are working to bring the Coliseum Building back to life after it burned in 2020. She’s also the architect on the project and owns the firm Urban Design Perspectives.
