See description of problems. <br />2. Silt fences need to be installed on Disturbance <br />Arse #1, <br />j. AR-6 needs to be installed. <br />4. Trses must be planted in Williams Canyon sad on ':he <br />roadside disturbance arses. <br />5• The sediment basin must be constructed. <br />Problems encountered during the implementation: <br />1, Disturbance Arena #2 and #3 era being ezaained from <br />the standpoint of solving the logistical problems o£ <br />removing the material. The method used on area #4 cannot be <br />used hers as the elopes are too steep to construct sny $ind <br />of bench from xhich equipment could work. The method used <br />on Area ~1 cannot be used because removal is needed rattier <br />than dust reshaping. lox that the thunderstorm season is <br />noon us it is our opinion that it would be inadvisable to do <br />sny work in regrading roadside disturbances #2 and #3 as <br />there would be little opportunity to control erosion by the <br />time the work ie completed. Therefore, regrading of areas <br />#2 and #3 will be delay9d until autumn and revegetation <br />implemented at that time. <br />2. Disturbance Area #4 needs to have the grades <br />ed~ustad. In order to remove the material a bonch needed to <br />be construoted out of the fill material. This resulted in <br />the produotion a£ a longitudinal shape Lhat is eomnwhat <br />different from that .SnLendod. To eorreot the problem a <br />large dozer meet be acquired that hoe a cable and winch <br />attached. This will allow the use of a email dozer to <br />finish grading the slope while the large dozer, narked cn <br />the roadway, holds the small dozer on the elope and helps it <br />to move up and dove the steep elopes. <br />
