RE:Weir Hill Barrens Habitat Management Weir Hill Weekly Report 4/26/2020
Dear Conservation Department and Planning Board,
As of 4/26 the Barrens Habitat Management at Weir Hill is essentially complete. 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.
