The stadium was upgraded multiple times in the 1980s beginning with replacement of bench seats with chair back seats and waterproofing of the east and west stands in 1985. The playing surface was moved to the south to center the field in 1986. The north and south ends of the stadium were waterproofed and chair back seats added in 1987 to bring those sections up to date with the 1985 improvements. Also in 1987 the press box was redecorated, a few more seats were installed at the upper portion of the west lower stands, and all seating within the stadium was renumbered using a uniform seat-width. By the end of the 1980s the stadium held 80,150 spectators.
