3082 . Fish shelters will be constructed below the top of the conservation pool by use of cleared trees which will be anchored. Selected trees will be left standing to provide roosts for eagles and other birds. 5. Areas disturbed and scarred including the material sites, camps, borrow areas, and the temporary roads used during construction will be rehabilitated by grading, landscaping, and refilling trenches. Surfaces of borrow pits and waste areas shall be left in a reasonably smooth and even condition and may require trimming as directed by the Bureau. Final excavated surfaces of borrow pits shall be graded to slopes not steeper than 11:1 below elevation 4,880, and not steeper than 5:1 above elevation 11,880. Denuded areas in the vicinity of the marina, the downstream right abutment borrow area, adjacent roadwork on the south side of the reservoir area, and borrow areas above elevation 11,880 comprising about 650 acres will have the topsoil re- placed. Topsoil will be spread to an approximate thickness of four inches and shaped for future revegetation. . 6. The Table Mountain riprap source comprising about 20 acres was chosen from several alternative areas because of its remote location and limited view from the general public. Prior to any operations in the rock source area, the contrac- tor will be required to submit for approval, his plans for developing the source and transporting the material to the damsite. This plan shall inClude all environmental protec- tion aspects including landscape preservation, dust abatement, etc. A specific elevation or definition of the limits per- mitted for quarrying will be included in the Pueblo Dam specifications. The specifications will also include the Bureau of Land Management's environmental requirements governing the use of the quarry. Alignment of riprap haul roads and access roads will be specifically designated by the Bureau. Drainage will be provided to insure the quarry does not pond water. Quarry slopes will be rounded and shaped to provide a natural appearance. Waste materials will be disposed of in the exhausted areas of the rock source or in approved areas adjacent to the source. 7. The Construction Field Office was landscaped to improve the appearance of the area and blend with the surrounding area. 46 .
