Abstract: System and apparatus for filtering drainage which includes a configurable and adjustable rigid frame, hanger support structures adapted to contact a surface of a drainage structure, and a sediment bag. The frame may be adjusted or configured by modifying the location of connecting fasteners and/or by altering the orientation of frame components. Additional embodiments provide for an overflow gap comprising a vertical distance between an above grade surface of a drainage structure and the rigid frame, wherein the overflow gap is capable of allowing runoff to bypass the sediment bag when the sediment bag is obstructed. A configurable lifting tool device adapted to lift inlet grates and inlet filter devices includes a lifting bar, a plurality of connectors, a plurality of lifting arms, and a plurality of lifting hooks adapted to contact a grate and/or an inlet filter device lifting bar.
