dw <br /> Chapter 4 - Best Management Practices for Erosion and Sediment Control <br /> Channel Flow Applications <br /> 1 . Bales shall be placed in a single row, lengthwise , oriented perpendicular to the <br /> contour, with ends of adjacent bales tightly abutting each other. <br /> 2 . The remaining steps for installing a straw bale barrier for sheet flow applications <br /> apply here, with the following addition . <br />+ <br /> 3 . The barrier shall be extended to such a length that the bottoms of the end bales are <br /> higher in elevation than the top of the lowest middle bale to assure that sediment- <br /> laden runoff will flow either through or over the barrier, but not around it . (See Plate <br /> 4 . 05f <br />+ Maintenance <br /> 1 . Straw bale barriers shall be inspected immediately after each rainfall and at least <br />.. daily during prolonged rainfall . <br /> 2 . Close attention shall be paid to the repair of damaged bales , end runs and <br />+ undercutting beneath bales . <br /> 3 . Necessary repairs to barriers or replacement of bales shall be accomplished <br /> promptly. <br /> 4 . Sediment deposits should be removed after each rainfall . They must be removed <br />+ when the level of deposition reaches approximately one-half the height of the <br /> barrier. <br /> 5 . Any sediment deposits remaining in place after the straw bale barrier is no longer <br /> required shall be dressed to conform to the existing grade , prepared , and seeded . <br /> —n I <br /> nl <br /> .I = <br /> =m <br /> I 'n i <br /> m= ' m <br /> i ' I <br /> nl <br /> I nl I II I <br /> III 11 111 III Id III III I <br /> i <br /> Sts ]9S3 xrrm��K�xs. <br /> Plate 4. 05e Proper Placement of Straw Bales at the Toe of a Slope <br /> Source: HydroDynamics, Inc. <br /> 4-19 <br />
