Florida Erosion and Sediment Control Inspector's Manual �+ <br /> Erosion and Sediment Control <br /> The construction of the sediment basin shall be carried out in a manner such that erosion and <br /> water pollution are minimized downstream . <br /> Final Disposal <br /> When temporary structures have served their intended purpose and the contributing drainage <br /> area has been properly stabilized , the embankment and resulting sediment deposits are to <br /> be leveled or otherwise disposed of according to the approved pollution control plan . <br /> Maintenance <br /> The embankment of the basin should be checked regularly to ensure that it is structurally <br /> sound and has not been damaged by erosion or construction equipment. The emergency <br /> spillway should be checked regularly to ensure that its lining is well established and ,■, <br /> erosion-resistant . The basin should be checked after each runoff-producing rainfall for <br /> sediment cleanout. When the sediment reaches. the cleanout level mark, it shall be removed <br /> and properly disposed of. <br /> Information to be Submitted for Approval <br /> Sediment Basin designs and construction plans submitted for review to the appropriate <br /> regulatory agency shall include : <br /> 1 . Specific location of the dam . <br /> 2 . Plan view of dam , storage basin and emergency spillway . �• <br /> 3 . Cross-sections and profiles of dam , principal spillway and emergency spillway. <br /> 4 . Details of pipe connections , riser to pipe connection , riser base , anti -seep collars , <br /> trash rack , and anti-vortex device . <br /> 5 . Runoff calculations for 10-year frequency storm . <br /> 6 . Storage Computations <br /> a . Total required <br /> b . Total available <br /> c. Level of sediment at which cleanout shall be required ; to be stated as a <br /> distance from the riser crest to the sediment surface . <br /> 7 . Calculations showing design of pipe and emergency spillway. <br /> .r <br /> 4-94 <br /> err <br />
