Ryan:
The proposed cobble swale, approximately 175 feet east of the westerly end of the Canyon Loop Trail Improvements, was originally indicated on the approved plans to be constructed at
the top of a proposed 2:1 graded slope, starting just prior to the proposed timber step assembly #2, and running the length of the slope to the westerly beginning of this trail improvement
project. During site construction, it was determined that the 2:1 slope grading is not appropriate. Therefore, the channeling of "rain event run-off" via a cobble swale was diverted
to be constructed immediately adjacent to the new proposed timber step assembly #2. This modification is projected to provide stronger protection of the adjacent hillside terrain than
the originally-proposed swale location.
Thanks

Good morning again Dick,
I hope you're doing well. Can you look at the notes from November 29th attached? It includes the cobblestone swale on the West End of the project. I know these were slightly relocated
due to drainage and the oak tree.
Can you send me just a paragraph with your professional reasoning why we did. I don't see it being an issue, I just wanted to include it in our notes for FWS.
Thank you,
Ryan

**Please exercise caution when opening attachments or clicking links, especially from unknown senders.** Hi Ryan,
Please see attached for the monitoring reports for the weekly check-ins for last week and for the planned ground disturbance this week. I apologize for forgetting to send the one last
week prior to Monday morning, but I think you were on vacation still anyway.
I'll give you a call a little later in the morning to catch up about where the project's at.
Thanks!

Danny was running both pieces of equipment simultaneously on Tuesday morning until the monitor was able to get him to stop. I’ve asked Endemic to remind him, if it happens again, that
this was an agreement with USFWS in order to minimize undue disturbance to gnatcatchers from having two pieces of equipment running at the same time along the trail.
* One of the crew members mentioned being able to disturb 9 feet of trail width (see page 9 on the 10/27 report). Alex will be following up with that today to find out what they are
talking about but the monitors have been stressing to them that they need to stick to what has been approved (i.e. a 5-foot wide trail unless it’s in one of the areas like the gabion
walls or gazebo areas) and so far the crew members do seem to be following the monitors.
* There seems to be repeated confusion with the crew about working in areas that aren’t approved for work, i.e. areas that are specifically written in Dick’s plans as “existing trail
protect in place.” See the area below, this is at least one of the areas that the crew is trying to work in and that monitors have had to show them are not included as part of the construction
plans. I told Alex that ultimately this is a question for you and Dick and that if you are comfortable with them grading the trail itself to smooth it out or whatever then that’s your
decision but that they should not cause any permanent vegetation loss in these excluded areas, at least not until after all other veg removal has occurred so that we can be sure that
they won’t exceed the acreage that has been allocated. From a bio perspective ideally they’d follow the plans and not remove anything at all in these “protect in place” areas but if
really necessary it should come at the end of all other removal work and only after acreage has been pre-confirmed.
* As of the end of last week the project has permanently removed approximately 0.0295 acre of CSS, or approximately 16% of the approved limit of all CSS.
Finally, Alex had a couple questions for me that I told her I’d pass on to you because I think they fall more within your area.
1. Should the crew be removing vegetation or casting it aside into piles on the side of the trail? This is not specified in the MMRP, but it does say in the MMRP under the Aesthetics
measure that vegetation piles should be, “staged and screened from public view in a designated construction staging area. Staging areas shall be approved and subject to periodic field
inspections by the City of Diamond Bar Parks and Recreation Department, or responsible designee(s).” This indicates to me that they shouldn’t be just casting vegetation to the side
of the trail as they go but I wanted to confirm an approach with you.
2. Does the project have an oak tree permit? This was pointed out in the original bio report that removal or pruning of oaks and walnuts (both of which are on-site and may require pruning)
may require a permit under Chapter 22.38 of the Diamond Bar Municipal Code; however, I’m uncertain if the City itself would need a permit for its own project or if any pruning would
simply be conducted under the City’s oversight pursuant to the municipal code.
Again I won’t be able to make it to the meeting this morning. However, I am happy to talk over the phone later today if you want to catch up on any of these items or make sure we’re
in agreement with everything. I will also be in touch with Alex later today as well to follow-up on things.
Thanks!
