Back of napkin figuring here but 2,000 ft of levee at 6 ft tall and 3:1 side slopes with 20% compaction is 16,000 yards. At $1.65/yd your at $26,400 just in levee construction
At a 2:1 side slope with 20% compaction you are at 12,800 yards, times $1.65 equals $21,120.
Obviously if you are tying in to two existing ridges the average levee height will be less than 6 ft and yardage will decrease, but can you quantify that?
