The city of Minneapolis is once again setting its sights on a section of Nicollet Mall for redevelopment, and as in the past, not everybody is happy with the plan. It's already been announced that Target stores Inc. plans to build a new headquarters on the mall. Now the city, along with a local contractor, want to raze a block along the south end of the mall to make way for a new Target store and office tower. But some tenants on the block don't want to leave and charge the city with bulldozing the plan through.
