Information. Design information for each pond is shown in Table 2, i~7nbankment <br /> Design, and Figure 2, Typical Sedimentation Pond Emba nkment Cross Section, <br /> while the location of each East Pyeatt sedimentation pond is shown on the <br /> Johnson/Pyeatt Drainage and Sediment Control Plan Map, Map TR-486-1, and on <br /> the East Pyeatt Sedimentation System Map, Map TR-486-4. <br />The hydrology of the East Pyeatt drainage basin was also modeled to determine <br />the effectiveness of the proposed sediment control plan. All model input <br />parameters and results from the study are shown in Appendix C, East Pyeatt <br />Hydrologic Model, Appendix D, Curve Number Determinations, and Appendix E, <br />Sedimentology Parameters. The results from this model predict that during a <br />10-year, 24-hour precipitation event, the peak settleable sediment concentra- <br />tion at the outflow of the final pond will be 0.0007 ml/1. <br />The design for each impoundment in East Pyeatt Gulch is shown on the East <br />Pyeatt Sedimentation System Map, Map TR-486-4, and the embankment design <br />details are shown on Figure 2, Typical Sedimentation Pond Embankment Cross <br />Section, and Table 2, ESnbankment Designs. <br /> <br /> <br />3 Revised 8/86 <br />
