<br />FLOOD FIGHTING METHODS 2003 <br /> <br />6.3A <br />Page 49 <br /> <br />Lumber and Sack Topping <br /> <br />With this method, wooden panels are used on the <br />waterside shoulder and reinforced on the opposite side <br />with sandbags. The method is used to raise low reaches <br />during high water (see Figure 15). Stakes 2"x 4"x 6' should <br />be driven on the waterside shoulder 6 feet apart. Dig a <br />shallow trench and line it with empty sandbags to provide <br />a seal. Pre-constructed wooden panels are placed in the <br />trench and nailed to the landside of the stakes. This wall <br />should then be backed with enough sandbags to support <br />the panels against the expected high water. In some <br />cases, it may be practical to back the panels with tamped <br />earth in lieu of sandbags. Attach 2"x 4"x 1 0' lumber <br />kickers to the stakes that support the panels, and drive 2' <br />stakes into the levee crown. Use at least two nails at each <br />joint to ensure rigid construction. <br /> <br />Lumber and Sack Topping <br /> <br /> <br />2 x 4-in. stakes as needed <br />to secure panels to levee <br /> <br />Waterside Levee ! <br />Shoulder <br /> <br />_..,,' r/ <br /> <br />.' ,< <br /> <br />. ,,' <br />_\\ /" <br /> <br />., /- \\C.. . <br />- \1/2 x 4 - in. stakes <br /> <br />Figure 15 <br /> <br />20 <br />
