DAILY BIO-MONITORING REPORT
Date:11/11/22 Day:Friday
Project/Stage of Project:Diamond Bar Canyon Loop Trail Improvement, trail maintenance
Name of Bio-monitor:Karly Moore
Location:Diamond Bar
Location Description:Coastal Sage Scrub and Coast Live Oak Woodland, behind residential area
Map # (If applicable):N/A
Bio-monitoring Activity
Start Time:0652 End Time:1140
Bio-monitoring Notes:
●No new vegetation impacts.
●The excavator was parked on the trail overnight.
●The crew using the mini excavator worked on adding more stairs along the south trail loop at a gabion
walls (Figures 1 & 2).
●The gabion wall material was delivered. Some pallets containing the materials were staged along the
edge of the trail (5-9 ft. From the trail edge).
●All biological resources were monitored and no adverse impacts occurred.

Bio-monitor Notes:
The mini excavator continued digging stairs along the south loop trail. When the excavator finished the figure 8
section the operator moved it to the upper pad and began excavating for the gabion.
Danny used the skid steer to transport the pallets holding the gabion cages. He staged three pallets along the edge
of the trail from 5 ft-9 ft. They were placed on dried mustard stalks. I asked what the work limits were for
staging the material and he said 5-15ft, and that he was placing them where there was no vegetation. I reminded
him to limit the disturbance to the vegetation.
Around 11:00 the workers began assembling by hand the gabion cages. At 11:25 the operator said he was done
with excavating and the remainder of the day would focus on gabion cage assembly. I contacted Alex Eagleton
the Endemic Environmental Services Project Manager, to see if we needed to stay and monitor assembly work.
She confirmed that if the digging and vegetation removal was down and no biological resources would be
impacted we could leave. I confirmed with the operator once again that digging and veg work was done, he said
the mini excavator would be parked at the start of the trail improvements, and I reminded them to pick up trash
and secure the lids on the cages.
