The latest owners of the long-vacant Sears store and surrounding block in downtown Salt Lake City want to tear down the building. Intermountain Healthcare bought the iconic property at 754 S. State St. and nine adjoining parcels on that block in December. Then, three months ago, the hospital system applied at City Hall to demolish the empty, 75-year-old, faded beige department store and a former auto repair shop to the west. So far, though, the Salt Lake City-based nonprofit chain hasn’t publicly shared its future vision for the key downtown locale and its sizable parking lot, which is currently fenced off and used for various kinds of storage.
