Dick,
Please see attached. This is the only copy that I have received to my recollection of the trail design. It's incomplete so I don't have the detail pages but it at least shows the basic
design. Anyway, this is specifically what we used to calculate permanent impacts for the project and this is what we emailed USFWS about.
So given the expanded trail and the disturbances out there, my question for you is this: are the areas that are currently being "temporarily" impacted and that will be re-seeded with
the erosion control mix later included in the areas that are shown as impacts in this PDF? If they are already included within the highlighted impact boundaries in this PDF then I think
we are all good. They have already been factored in as permanent impacts to be mitigated under the HMMP and that's an easy response to give back to USFWS. If these are different areas
that are not part of the acreage that we calculated then it may be a little more difficult to parse out.

Ryan,
Please note that these are construction plan CAD drawings and not a GIS overlay drawing so you won't find anything close to properly intersected and closed polylines depicting the impacted
areas, etc. That said, you would have to create the closed polylines by intersecting the various item layers that represents the outer limits of construction / impacted areas. Attached
is a PDF plan w/ lines highlighted in yellow that represents the outer limits for your reference in creating the close polygonal areas that you would need for determining the impacted
areas.
Thanks,
Khoon

Khoon,
Please find attached a response from GIS again. There appear to still be gaps in the data and our GIS guy on this project is wondering if they are intentional or if there are additional
layers that need to be added in.
Thanks!

Hi Ryan and Dick,
Please see below responses to the inquiry:
Item 1 - Yes, the red lines represents the proposed ditches which are located behind the proposed gabion walls. In regards to impact, the ditches and grading daylight lines should be
taken as the limits of disturbance.
Item 2 - The base file would be the pertinent file of interest, see "19-2266 Alignment & Profiles - South Loop.dwg". The layers that you would probably be interested in looking at is:
a. "_PG-DAYLIGHT" for the grading daylight lines b. "_DITCH" for the ditch lines
Hope that helps.
Regards,
Khoon

Ryan,
GIS has looked at the CAD files that were supplied and had some questions related to the two attached screenshots.
1. Canyon_Loop_CAD_1 - are the red lines supposed to be ditches or anything else that need to get incorporated into the impact calculations? We aren't sure what those represent.
2. Canyon_Loop_CAD_2 - this image depicts the list of CAD files that were included in the download package. First, we aren't sure which specific files are supposed to be used from
this list. Can the engineers identify the appropriate files so that we make sure we're using everything that's intended? Second, we aren't sure which layers specifically constitute
an impact as opposed to the existing condition. We also need clarification on this.
Thanks!

Hi Jeff,
MBI needs our CAD files to pull coordinates from for their environmental work so when you get a chance tomorrow morning, could you please do a pack and go of the CAD files and email
that over to Dick and copy me, thanks. BTW, the project is going to council for bid authorization tomorrow so it's finally happening.
Thanks,
Khoon
