<br />FLOOD FIGHTING METHODS 2003 <br /> <br />6.3A <br />Page 44 <br /> <br />stakes attach the two top layers with one button and the <br />two bottom layers with another. The buttons line up with <br />the stakes that are four feet apart. There should be four <br />buttons securing the two envelopes. <br /> <br />Using a continuous piece of twine, hang tied-bags from <br />stakes in a zigzag fashion as shown, in Figure 10. Tie a <br />double half-hitch knot below the knot in each sandbag. <br />Place each bag so that it hangs at the middle of the plastic <br />directly below the stake between the two stakes from <br />which it is suspended. Attach twine to every other stake <br />with a double half-hitch. Add a second row of tied bags <br />suspended from the stakes previously skipped. These <br />bags will keep the visquine lying flat against the levee <br />slope in windy conditions. <br /> <br />If the upper portion of the slope needs protection, use an <br />additional envelope. Be sure to place the upper layer over <br />the lower layer by 2 to 3 feet. Finally place sandbags along <br />all seams to prevent wind and water from entering the <br />envelope. To prevent slippage, make sure the top seam <br />cap is half on the plastic and half on the levee as shown in <br />Figure 10. If the levee slope is too steep, some of the bags <br />on the seam may be tied off with twine to the stake above <br />the envelope for support. <br /> <br />Remember, wind is your worst enemy. When using <br />visquine, be sure all seams are secured with sandbags, <br />and make needed repairs as soon as possible. <br /> <br />15 <br />
