Thank you, Anthony. Would you agree then from your email below that Danny did not implement BMPs previously, if there was significant erosion following previous rain events? I can respond
to FWS that the contractor did not install BMPs previously but will install them prior to the next rain event later this week, I just want to make sure that what I say is accurate and
that you’re in agreement since I’m putting it in writing. I assume the BMPs will include silt fencing, wattles, and other methods to contain soil and/or prevent large rills or erosional
features from developing. Looking at the photos that have been sent to the City and to the agencies, I think the concerns that they’re voicing are that sediment has just been sidecast
into areas that are otherwise supposed to be untouched. I don’t know how to resolve that short of pulling it all back very carefully at the end of the project, but they can at least
attempt to prevent it from going in deeper into the vegetation from rainfall, particularly the larger mounds that have been built up.

Subject: EXTERNAL: BMPs/Erosion Control Canyon Loop trail Improvement Project
Good afternoon Danny,
Per the approved plans, specifications and special provisions of the subject project, eroded sediments shall be retained on site. During the most recent rain event on the trail, several
areas experienced significant erosion. As such, please install erosion control measures as required to prevent any further erosion prior to the next rain event. Please reach out to
me with any questions or concerns. If you would prefer, I am happy to meet with you on site to discuss.
Regards,

can just get some sort of written concurrence from USFWS that the project will not require any additional measures beyond what is already being incorporated, and I had hoped to connect
with the appropriate person at USFWS to initiate that conversation. I had planned to put together a brief memo describing the project, past survey efforts, and proposed avoidance measures
and hopefully get something in writing back that the project impacts do not meet the level of significance requiring any sort of HCP and that the proposed measures are adequate to protect
the species.
Can you please point me in the right direction for whom I could talk to to get the ball rolling?
Thank you!

u start working on your insurances, business license, and submittals to avoid any delays after we receive the green light from City Council. I will provide more details as we go, but
hope this helps. Please let me know if you have any questions.
