Bio-monitoring Activity
Start Time:02:00 End Time:04:00
Bio-monitoring Notes:
●The biologist surveyed the site for new vegetation disturbance,construction progress,and compliance
with permit requirements.
○No new permanent vegetation disturbance occurred,several areas where the crew was cleaning
up excess dirt on trail edges was noted to be assessed as either a temporary or permanent impact
(Figures 1 and 2). Biologist will evaluate the impacts next Monday when work is complete.
●The weekly site meeting between city, bio, and engineering occurred at 2pm, Friday is the last work day.
●All biological resources were monitored and no adverse impacts occurred.

Vegetation Impact Section
Was vegetation impacted by project work activity? Yes
If yes, then:
Habitat Type: Coastal sage scrub and prickly pear scrub
Type of Vegetation Impacted: Some coastal sage scrub
What type of impact occurred? Temporary and Possibly permanent.
Square Footage of Impacted Area: Approximately 75 square feet
Bio-monitor Notes: The biologist noticed that there were parts of the trail where soil had spilled over and
covered the vegetation. The crew had begun cleaning up some of the dirt along the sides, and it became evident
there may be permanent impacts, but it will be difficult to assess until the trail edges are finalized. The biologist
will determine the status of these temporary impacts during the next visit.
