to <br />1 <br />' <br /> Our 1974 recommendations were to ditch the inside of the road to collect <br /> runoff water, then divert this water off the road at four places into <br />' natural drainage ways or on ridge crests. Those recommendations have <br /> been carried out, but periodic maintenance will be needed to keep the <br /> inside drain ditch open. <br />' Plants of native species produced from hand seedings on the fill slopes, <br /> including the berm, were conspicuous in 1914 (Figure 11, 1974 report). <br />' Seedlings of mountain-mahogany showed up abundantly in the spring of <br />1975. Additional seedings are recommended to hasten revegetation. <br /> 4. Face of the Fill Area <br /> R <br />d <br />ti <br /> ecommen <br />ons <br />a <br /> (a) Backslope the edge of the fill to a slope of 2 to 1. Alternatively, <br />' create one or more flat benches across the slope, add good soil. <br /> (b) Compact the surface of the face of the fill. <br />' <br /> (c) Revegetate by hydromulching using the same seed recommended for <br /> the haul road. <br />' (d) Sow acorns of Gambels oak in clumps to break up the straight <br /> lines of the fil]. <br /> Action <br /> Use of the edge of the fill led to periodic disturbance of the face of <br />' the fill, and storm runoff periodically eroded the face. An undisturbed <br /> part of the face revegetated quite well by 1974. In February, 1975, a <br /> heavily racked drainage channe] was constructed to carry storm runoff <br /> over the face of the fill. The face was then repaired and one step or <br />' bench was cut across it. The whole face was then seeded to grasses by <br /> hydromulching. Arrangements were made with a nurseryman to establish <br /> Gambels oak and other woody plants. <br />' <br />1 <br />1 <br /> <br />1 <br />1 <br />1 <br />
