A field review of winterization work was also conducted <br /> by Dave Gloss and Suzanne Layne on Friday, December 4, 1998. <br /> Dave and Suzanne concluded that, with one exception, all winterization needs were complete. <br /> They determined that the downslope side of the water bars at Station 80-85 needed compaction <br /> to keep them stabile through the winter. Patricia checked the waterbars today and observed that <br /> the compaction had been completed. She also noted that one segment of sediment fence in the <br /> • same area had partially collapsed and needed to be re-established. You agreed to have the fence <br /> repaired as soon as possible. <br /> During the 12/4 field review, Dave and Suzanne determined that all items noted in the 11/t7/98 <br /> daily diary and the 11/20/98 letter from me, had been addressed and were either completed or in- <br /> terim erosion control measures were in place which would be adequate until all earth work is <br /> completed next spring. <br /> Of specific concern from the diary and letter was the status of work at Station 80-85. Erosion <br /> control measures. including silt fence, straw bales,sediment traps, water bars and seeding, which <br /> Dave and Suzanne felt were adequate to minimize soil erosion until final earth work is complete, <br /> have been implemented in this area. Maintenance of erosion control measures will be necessary <br /> early next spring. It also appears that the COMP recommendation to surface this area with 4-6 in <br /> angular rock will not he necessary. The existing material is comprised of large rock and should <br /> provide a stable surface with minimal erosion. Dave and Suzanne's recommendation is to drop <br /> the requirement for adding 4-6 inch rock and instead require the area to be seeded and install <br /> straw bale sediment barriers at the bottom of the slope, to be left in place after final earth work. <br /> They felt that this would meet the intent of the recommendation in the COMP. Based on their <br /> input, I concur with the recommendation for this change to the COMP. <br /> In a previous discussion, Patricia had told Bryce Romig that berms along thF road at the north <br /> end of the project could be left in place over winter if breaks were put in the berms to allow wa- <br /> ter to run off the road. Breaks have been installed at the cut/fill points, north of STA 130+00, <br /> and the breaks are armored with rock. Sediment fences are installed at the bottom of the rock ar- <br /> • moring. <br /> S <br /> Caring for the Land and Serving People Printed on Recycke Peoe � <br /> 01-19-99 01 : 57 RECEIVED FROM:9707250038 P- 02 <br />
