A <br />survey line may be used to indicate the proper <br />placement of the emergency levee. This line <br />may be marked with wooden stakes, string <br />lines, or field lines using powdered lime or <br />flour. A good improvised marking tool is a <br />fertilizer spreader filled with flour. <br /> <br />A key trench is essential for success. The key <br />trench is an excavation 4 to 6 inches deep and <br />between 18 and 24 inches (two sandbags) wide. <br />The key trench provides an anchor for the <br />emergency levee. Key trenches may be dug by <br />hand, or more commonly are excavated with a <br />small backhoe. Poly is placed in the key trench <br />and anchored with several sandbags. Be sure <br />that the poly is placed on the water side of the <br />levee. <br /> <br />4t ~ <br /> <br />I <br />I <br />I <br />, <br /> <br />tt <br /> <br />12 <br />
