The remaining heavy cutting equipment is scheduled to be moved off site early this coming week, and contractor will be taking some of the larger stumps down in size using a chainsaw. This week, a tracked chipper was brought on site 4/22 and chipping was completed quickly. Chips were able to be dispersed in multiple locations outside of the cutting units. A forwarder was brought on site 4/24 and on 4/2S all logs were forwarded to the Stevens St parking area. By 4/26 all logs were transported off site by logging trucks. Final mowing in Unit 1 was also completed on 4/25. Jeff Denoncour was on site 4/25 during the forwarding operation. On 4/26, Jeff Denoncour did a full walk through across cutting Units, and they remain in good condition following canopy thinning, chipping and forwarding. While rutting and soil disturbance was minimal, Jeff used hand tools to begin smoothing areas where piling and rutting had occurred. Jeff also repaired water bars along the main gravel access road now that all but one piece of equipment has been moved to the staging area and in preparation for rain forecasted on 4/26-4/27. The intermittent stream crossing and dirt access road were the areas we were most concerned about for rutting and soil disturbance, especially while forwarding logs out of the cutting area. During the forwarding, additional logs were used to corduroy the wetter areas on either side of the wetland crossing mats. As expected, the forwarder caused more disturbance to the area on either side of the wetland mats than the cutting equipment, due to size of the forwarder and heavy loads.The contractor brought a mini excavator the day of forwarding to be able to repair and smooth the wet area on either side of the crossing after all cutting equipment had crossed for the last time, Some sedimentation occurred downstream during the forwarder crossings and while removing the crossing mats and corduroy logs. Sedimentation was minimal and was captured by leaf debris and vegetation shortly after flowing downstream. By 4/26, the water flowing through the intermittent stream crossing, and downstream, was flowing clear. Both roads down to the crossing held up well during the project. A water bar was created along the steep section of road leading down to the crossing in the event we do see sheet flow down the roadway. With .7 inches of rain forecasted between 4/26-4/27 we will be watching this area closely as well as other cutting units. The mini excavator remains on site if we see any erosion along the roadways following the rain or need to create additional water bars. We expect this area to naturalize and revegetate as it has with past clearing projects. it r 12 A a- t gg y k �r ky[-M 1- w 4 i�"t'�f_�v�k.
