All,
Please see below, USFWS is happy with the response that I provided and Lauren will get back to Robb et al. as well regarding the concerns that were raised.
Thanks all for your assistance in helping me fill in the gaps with my project knowledge!

Hi Ryan,
Thanks so much for the detailed response. We thought the pictures looked pretty much consistent with the plans you had sent for our review so it's good to hear that everything is going
as planned. Also, thank you for getting the additional BMPs installed ahead of the rain. We will let the folks expressing concern know that the project is in compliance with what was
presented to us.

Hi Lauren,
Thank you for the notification, I appreciate it! I apologize for the delayed response as well, I’ve been out of the office.
Regarding the two points below:
1. The project is designed to reduce and/or prevent future trail erosion, which has historically been an issue with the trail. The City has in the past required a contractor to come
out to regrade the trail after rains due to the ruts and rills that develop following big events. Regarding current erosion control BMPs, earlier rainfalls this season mostly occurred
prior to the bulk of the grading on the project, so there was minimal, if any, erosion of project materials during previous rain events. The surrounding areas are generally at relatively
flat grades with the trail anyway, which further reduces possibilities for erosion outside of a few steep areas. Unfortunately some material has been side cast during the construction
process. The City’s Maintenance Superintendent has directed the contractor to install appropriate BMPs today and tomorrow before the next forecasted rains this Thursday to prevent any
of the current stockpiles/material from eroding into adjacent vegetation, and this will be a consideration moving forward as well. Excess materials will also not be left in place and
will be removed before the project is complete.
2. The project is being built according to plan. This calls for an area wider than 5 feet to be cleared during construction in areas where the cross-slope grade immediately adjacent
to the final trail bed does not fall within the requisite 2% minimum and 5% maximum cross-slope grades against the new trail. These areas will not be left bare like this and they will
not constitute a part of the future trail. The final trail width will be 5 feet. Once the adjacent areas, where necessary, have been fine-graded to the correct level they will then
be pulled back and reseeded with the “native erosion control mix <https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ssseeds.com%2Fproduct%2FBasic-Native-Erosion-Control-Mix.aspx&
data=05%7C01%7CRyan.Winkleman%40mbakerintl.com%7C2a927c7955e246d72ca108dad269e0b4%7C4e1ee3db4df64142b7b9bec15f171ca4%7C0%7C0%7C638053649449694450%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV
2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=ONwnGliUDFhrhHJ%2B8pbjsPWkDmJPUHDAdLis2dA53gE%3D&reserved=0> ” from S&S Seeds to further control future erosion along the
sides of the trail. These “expanded” areas were what were calculated and sent to the Service as permanent impacts and they are what will be mitigated through an HMMP. The current permanent
impacts to CSS vegetation along the sides of the trail are still well within what was calculated and presented to the Service during our earlier conversations a couple months ago.
a. Of 0.009 acre of California sagebrush – black sage scrub that was calculated for impacts, the project has permanently removed 0.0049 acre.
b. Of 0.128 acre of disturbed California sagebrush – black sage scrub that was calculated for impacts, the project has permanently removed 0.0572 acre.
c. Of 0.050 acre of coast prickly pear scrub that was calculated for impacts, the project has permanently removed 0.0159 acre.
These are current prior to today. There was some minor grading today that I don’t have the numbers for yet. Again, these are the areas that have been widened along the trail and that
are currently being questioned in the correspondence you received from Robb et al. They were what was factored in as permanent impacts in the numbers we previously provided to you and
they’ll be mitigated for on-site.
Please let me know if you have any other questions, and please confirm that you’ll handle the ITP response on your end. Thank you!

Hi Ryan,
I wanted to give you a heads up that we've gotten a complaint from a concerned citizen about the impacts associated with the Canyon Loop Project. We just wanted to check in and make
sure everything is being implemented as laid out in the MND. The specific concerns appear to be regarding the erosion control BMPs and width of the trail. If you could confirm that
the project is being built as planned and that all BMPs are appropriately placed, we would greatly appreciate it and we will be happy to prepare a response regarding the ITP question.
