(1) A description of the following: <br />(i) <br />Final grading — specify maximum anticipated slope gradient or <br />expected ranges thereof. <br />Current slopes across the site are flat (0-1 % slopes). Reclaimed pond edge <br />slopes will be at a maximum of 3:1 slope to 10 feet below the average <br />water surface elevation and final grading will generally match the <br />surrounding topography in disturbed areas. The average elevation across <br />the site is 6210 feet AMSL and ranges from 6200 to 6220 at the gate <br />"final" operations area. All areas will be graded to match the adjacent <br />topography. <br />(ii) Seeding— specify types, mixtures, quantities, and expected time(s) of <br />seeding and planting. Concurrent reclamation will use the same seed <br />mix and planting methods. <br />Bluebunch Wheatgrass <br />Western wheatgrass <br />Crested Wheatgrass <br />Indian Ricegrass <br />5.0 PLS per acre <br />2.9 PLS per acre <br />2.0 PLS per acre <br />1.0 PLS per acre <br />A total of 44.7 PLS will be required for possible 4.0 acres of <br />final site reclamation at the gate area. ** (also various <br />trees/shrubs and wetland /riparian as selected by <br />applicant/landowner as previously stated to provide a more <br />diverse habitat.) <br />After replacement of topsoil on areas scheduled for reclamation, seedbeds <br />will be prepared using a disc type plow or spring rake harrow. Seedbeds <br />will be firm and clean tilled. The seeding operation shall be by drill <br />method. After seed application seedbeds will be mulched and crimped <br />stated below in (f) (iii), at a rate of 2000#/acre; weed control will be as <br />necessary. Recommended seedbed preparation date is June 15 - July 15 <br />recornmended for seeding. Dormant seeding recommendations are from <br />October 1 to April 30. Early October, just prior to the first hard freeze is <br />recommended as the most appropriate time for dormant seeding. Seeding <br />of stockpiled topsoil for stabilization will be broadcast and raked by hand <br />using the same recommended seed mix as above at. Any other areas <br />requiring broadcast seed application will be done at twice the <br />recommended drill application rate. <br />WestWater Engineering <br />APPENDIX C - 21 July 2012 <br />
