DAILY BIO-MONITORING REPORT
Date:1/12/23 Day:Thursday
Project/Stage of Project:Diamond Bar Canyon Loop Trail Improvement, erosion control installation
Name of Bio-monitor:Alex Eagleton
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:07:45 End Time:09:25
Bio-monitoring Notes:
●The biologist surveyed the site for new vegetation disturbance,construction progress,and compliance
with permit requirements.
○No new vegetation disturbance occurred.
○Today the crew installed v swales and backfilled behind the central gabion wall (Figure 3).
○Recent rains displaced tarping on spoils piles (Figure 4)and caused erosion along the stairs at
the south end of the trail (Figure 5).
●The excavator and skid steer were used to transport splash pad materials to the end of the trail.A drip
pan was in place at the beginning of the workday.
●All biological resources were monitored and no adverse impacts occurred.
