Memo - H. Bruce Humphries <br />Concerns <br />-5- <br />Submitted <br />November 16, 1989 <br />Resolutions <br />13. Reclaimed slopes should be regraded Cedar Heights Lenders The Division feels that grading <br />in an irregular manner to make terrain in an irregular manner is not <br />terrain more interesting. essential to accomplishing <br />reclamation. In this case, the terrain <br />will be irregular as a result of the <br />varied sizes of the fill materials. <br />14. Earthern berms not replaced by <br />non-eroding barriers should be moved <br />away from road shoulders and <br />seeded to reduce sedimentation. <br />Truck escape ramps also should be <br />seeded to reduce sedimentation. <br />The access road should be swept up <br />after the sandina_ season on a <br />schedule similar to city street <br />and state highway departments. <br />15. The proposed silt retention <br />facility should be sized for a <br />100-year storm event. <br />Greg M. Nagel These specific concerns were not <br />addressed in the Notice of Violation. <br />It would thus be inappropriate for the <br />Division to require Castle Concrete <br />to address them in order to comply <br />with the Board-ordered corrective <br />actions. The Division does believe <br />that the improved road drainage <br />will help alleviate these concerns. <br />Greg M. Nagel The Division feels that this is un- <br />necessary as we consider the 10-year <br />recurrence interval event as the <br />appropriate design level for <br />sedimentation control. The Division <br />also considers the 25-year event <br />appropriate for princioal spillway <br />sizing and the 100-year event <br />appropriate for emergency spillway <br />16. The water and sludge in the innundated Greg M. Nagel <br />area at the base of the Area One slide <br />should be relocated to the new Silt <br />facility. <br />The Division has recommended that <br />±ha± rastl' C^nCrctc Cv~~~yiy 'w-i iii ibis <br />s <br />or, as an alternative, place a 6-9" <br />granular filter layer at the bottom <br />of the inundation and slowly fill with <br />rock to the desired channel <br />configuration. <br />• <br />C~ <br />
