Grassed Waterway in Town of Seneca
This large structural erosion control project consisted of a 2,300 ft long, 30’ wide, 1’ deep grassed waterway system installed to control gully erosion caused by concentrated water volumes washing across a large tract of cropland. The waterway included a large 12" underground outlet system that was installed under the waterway to handle low water flows between storm runoff events. This grassed waterway has over 35cfs capacity and will convey all large storm events across the farmland in a non-erosive manner. Spreading the water volumes through a wide, shallow, sod channel that follows the natural contour of the land allows us to slow down the velocity of the water leaving the cropland. The completed project has an expected soil savings of 92 tons of soil saved per year on the affected acreage.
