[2] On March 20, 1901, the district commissioners granted permission to the American League to establish a baseball park at the location following an application including plans and specifications for the grand stand and the other supporting structures.

The land had been previously occupied by the Washington Brick Company in an area sparsely built at the time; the closest buildings were located more than 50 feet (15 m) from the outlines of the grounds.

No specific regulations for the establishment of baseball grounds were in place in the District of Columbia at the time.

The left-field line ran roughly north–south, with the left field measuring 290 feet (88 m).

[4] Boundary Field, in Northwest DC, had been the preferred site for the American League Senators, but its usage had been blocked by the National League, which still had rights to the site despite no longer having a franchise in Washington.
