Document Description
This project consists of the stabilization of two 2000 ft. long gullies after the removal of buried tires that were placed in the gullies for erosion control. The two gullies drain an area of 100 acres. Using regional hydrologic data, the flow expected from a 100 year storm would exceed 50 cubic feet per second. The upper half of both gullies have an average slope of 12%; the lower half 8%. Figuring the channel dimensions, the 100 year flow of 50 cubic feet per second, and soil texture; the maximum slope for a lined channel would be 8%. Grade stabilization measures would need to be taken on slopes greater than 8%. Compacted earth fill and a series of rock grade stabilization structures, will be installed in parts of the gullies that exceed 8%. 1,120' will be treated by this method in gully "A" and 890' in gully "B". Thirty rock structures will require a total of 2,750 cubic yards of rock, 4' diameter or less. Additionally, 5,400 cubic yards of compacted earth fill are required. The channel in between grade stabilization structures will be lined with 2-6" cobble, requiring 1,800 yards. The flatter part of the gullies below the grade stabilization structures will be lined with a coir erosion control blanket, requiring 32,000 sq. ft. All disturbed areas not covered by rock, cobble, or erosion control blanket will be seeded with a native seed blend, fertilized and mulched.
