Des Moines Register: Des Moines’ Landmark Review Board voted unanimously Tuesday to approve landmark status for the Crescent Chevrolet sign at 555 17th St., and renovation plans for the site where it has sat since 1968 call for restoration of the sign back nearly to its original condition — including new lights. Developer Krause+ is currently renovating the building. Big Grove Brewery will open a Des Moines location in the eastern half of the building, with retail and office space also in the works.
