Here is a foursquare, very compact stadium:  football field in green, softball and baseball diamonds in brown, surrounded by ten rows of seats on each of two levels for a capacity of 13,400.  The outside dimensions are only 500 by 390 feet.

The on-deck circles double as the throwing circles for the discus and the shot-put.  For the runners, there's room for 120 yards of straightaway before the finish line in front of section 11.  But the turns, with a radius of only 60 feet, are much too tight for an outdoor track.
