A stone-lined spillway and bioswale section featuring three-inch maximum river run cobbles grouted with concrete over a layer of Mirafi 700X woven geotextile fabric. The geotextile fabric extends two feet beyond the width of the cobbles. The swale is flanked by concrete curbs, with dimensions tapering from twenty-four inches at the back of the curb to the bottom of the swale at the toe of the slope. Additional sections show transitions to asphalt concrete or concrete paving over base rock and compacted native material.
