The drainage grate also includes an upper level comprising a plurality of upper plates, each upper plate of the plurality of upper plates defining a second plurality of drainage apertures. The drainage grate further includes at least one upper plate of the plurality of upper plates that is a folding upper plate hingedly coupled to the base such that the folding upper plate is individually movable between an open position and a closed position, wherein the folding upper plate in the closed position defines an acute upper angle relative to a horizontal plane.
