Hello Carol,
The Canyon Loop Trail Improvement Project in Diamond Bar has now begun. The contractor has a foot crew and a Bobcat skid-steer loader to assist with the necessary vegetation removal
for the trail widening.
The contractor is now also requesting to use a mini excavator in order to help smooth bumpier parts of the trail as well for gabion wall construction. The mini excavator is 68" wide,
comparable in size to the Bobcat. We had previously specified in my letter to you that only one piece of equipment would be used on the project. He has agreed to, if granted permission,
only using one piece of equipment on the trail at a time (either the Bobcat or the mini excavator but not both).
Is USFWS okay with this concession and allowing the additional piece of equipment as long as only one is in active use on the trail at any given time?
Thank you!

Ryan,
Please accept my apologies for the delay in responding to your request We have reviewed the City of Diamond Bar's proposal as presented in your July 22, 2022, letter. The information
provided therein included: project description, survey results, and avoidance and minimization measures. Because the work will be done outside the breeding season, will involve very
narrow zones of disturbance, and will be distributed across the territories of three coastal California gnatcatcher (Polioptila californica californica; gnatcatcher) territories, we
agree that the project is not likely to result in impacts that would warrant an Incidental Take Permit for the gnatcatcher.
We appreciate the City's willingness to offset impacts to coast prickly pear scrub at a ratio of 5:1, resulting in a total of 0.250 acres to be mitigated onsite. This will benefit the
gnatcatcher and the cactus wren (Campylorhynchus brunneicapillus), which was also identified as using the site. However, as specified in your letter, a total of 0.187 acre of gnatcatcher
habitat will be impacted in the course of the planned activities. The Service recommends that this loss be offset at a 2:1 ratio, for a total of 0.374 acres of coastal sage scrub. Because
it is clear from the territory mapping that the gnatcatchers are using the coast prickly pear scrub, that 0.250 acres of mitigation can be counted towards the 0.374-acre recommended
offset for gnatcatchers. The remaining offset needed to achieve the 2:1 ratio would therefore be 0.124 acres of coastal sage scrub. There appear to be ample opportunities within the
context of the site to achieve this goal. We would be happy to coordinate with you on appropriate plants to use for this purpose.
Please feel free to contact me if you have any questions. Thank you for the opportunity to provide input on the project.
Sincerely,
-Carol (she, her, hers)

Hello Carol,
As we have previously discussed and met about, please find attached a memo for you to evaluate the potential impacts on California Gnatcatchers from the Canyon Loop Trail Improvement
Project in the City of Diamond Bar. Although gnatcatchers are known to be present in the area, it is our belief that the project’s avoidance and minimization strategy and proposed habitat
mitigation outweigh the otherwise relatively minimal effects that the project may have on the species, and that the net effects do not rise to the level of the project requiring an
Incidental Take Permit to proceed.
If you have any questions or want to meet with me again, please don’t hesitate to let me know.
Otherwise we look forward to your response. Thank you!
