SECTION 5.6: SEDIMENT CONTROL <br />SC 2: EROSION LOGS <br />installation for Check Dam Applications <br />When using as a check dam, it should be placed in straight sections to <br />minimize the potential for erosion in the channel bend. <br />Installation for Curb Inlet Protection (Upstream of role!) <br />• Logs will be used upgradient of inlet perpendicular to and flush with the <br />curb. <br />• The maximum height of the curb log should be less than the top of the <br />curb opening. This is to allow overflows to occur during large rainfall <br />events even though sediment-laden runoff will enter the storm drainage <br />system. <br />• No less than two 10-inch diameter logs must be used in sequence, spaced <br />no more than five feet apart, upgradient of inlet. No less than six logs <br />shall be used if the 4-inch log is chosen. <br />• Incline at 30 degrees from perpendicular, opposite the direction of flow. <br />Installation for Curb Inlet Protection (Entrance of WOO <br />• Identify curb opening dimensions to determine how many logs are <br />required. <br />Place the log(s) end-to-end along the curb inlet opening. <br />Angle the ends of the log(s) towards the curb inlet opening. <br />TYPICAL STAKING PATTE' N , <br />ox. zP PLAN VIE41 mrsme. v.p <br />D E-sW mom M ?
