.~ Mr. Robert Sieyrist March 3, 1982 Page -3- 3. The statement that "All finished slopes adjacent to water surfaces will have a finished slope no~steeper than 3:1" is f inadequate. This statement should read as follows," A11 finished slopes from 5 feet above to 10 feet below the expected eaater line will have a slope no steeper than 3 horizontal to 1 vertical." 4. Please provide a permanent grass mixture for this site incorporating both native grasses and forbs. S. The staff suggests that a mixture of the following trees and shrubs be randomly planted: Trees Siberian elm Plains cottonwood hackberry boxelder Russian olive Shrubs Skunkbush sumac American plum Siberian peashrub Chokecherry Hanson hedgerose Western sandcherry Willow The trees should be randomly planted at 20-30 foot spacings and the shrubs should be clumped 6-8 feet apart with 6-10 of the same species per clump. The clumps should be spaced 50 to 75 feet apart after planting, a 3 foot water catchment basin should be created around each plant, immediately watered and mulched with wood chips. The seedlings should be watered 2-3 times during late spring and summer for the first 3 years. The expected survival would be about 50 to 75 percent. Please let me know if there is a problem with following this suggestion. 6. Please state how many acres of Land surface will need grading and topsoiling. 7. The staff recommends that the operator commit to a definite range of topsoil replacement. A review of the site and the soil infoz•mation indicates that it would be possible to salvage enough topsoil to replace to a depth range of at least 8 to 12 inches. 8. To increase wildlife use of the lakes, the staff recommends that the operator commit to the following: a. Irregular shorelines should be incorporated into the plan and portrayed of~ the reclamation plan map• b. Shallow areas should be created to provide for emergent aquatic vegetation.
