For the purposes of this USFWS email I think the most important parts of your email to understand are the trail width parts and those are what I will summarize. The BMPs will require a response from Anthony/Fabian. Can you please clarify why it’s necessary to take greater than 5 feet in order to achieve the ultimate goal of 5 feet wide? I can see this being a point of contention. If we can demonstrate that the expanded trail width that they’re calling out now is temporarily necessary for “X” purpose during construction then that’s a positive response we can send back, but we need to explain why it is necessary. In areas where the trail was less than 5 feet wide and is now greater than 5 feet wide during construction but will ultimately be reconstructed to 5 feet wide by the completion of the project, how will that be accomplished? I think the restoration is going to be in a specific area unrelated to the trail (like off on the northeast side?), right? So what is going to be done for areas that currently exceed 5 feet in order to cut them down to be only 5 feet at the end? In other words, they’re measuring out a 7-foot wide trail right now at least in some places, so what are those areas going to look like at the end? What’s going to happen to those extra 2 feet in order to say that the official trail is still only 5 feet wide? If I’m not articulating well please let me know.

The Bid Form (Item #12) indicates the construction of 571 LF of swales, as does the Construction Note #4 on the Title Sheet. Concrete swales are being constructed in (7) locations, as follows: * (2) locations for shade shelter pads * (3) locations where adjacent to new timber steps * (1) location adjacent to/behind Gabion Wall No. 1 * (1) location adjacent to widened trail at T-intersection with existing Summit Ridge Trail. At this location, the completed concrete swale will be filled up with rock cobble, so as to avoid pedestrians’ mis-stepping off the trail and into the concrete swale. * Reduction of Erosion and Surface Soil Displacement * Throughout the trail length, (exclusive of the steep segments now receiving timber steps) where the grade of the trail, longitudinally, is great enough where potential erosion down the trail surface is likely (historically been occurring in significant rain events), strategically-placed Trail Water Diverters are being constructed to quickly remove more significant flows of rain water, directing such flows off the trail and down the lower side of the trail topography while still in small quantities. All “run-off” water is being directed into natural vegetation areas, where it will be absorbed into the natural terrain in small volumes. There are (19) Trail Water Diverters (Construction Item No. 3 on the Title Sheet). * The bottom line goals for this project includes REDUCING natural erosion activities which this trail system has encountered over its many years of existence. * No run-off water, from this project’s trails improvement work, is anticipated to get within 650 feet of any established storm water conveyance systems. * Concerning the trail width: * All trail improvements are to be reconstructed to 5’-0” in width at the completion of the project (Construction Notes #1 on Title Sheet). * The note on the plans at various locations say: “Existing Trail/Protect in Place”. This note has been used in those locations where new grading and/or trail widening is not necessary. HOWEVER, (just as was anticipated), in order to widen those portions of the trail prior to/after these noted “protect-in-place areas”, there will be trail disturbance (within the existing 5’ trail width) due to hauling construction materials over them with mechanical equipment, and must be fine-graded and compacted again. The purpose of this Protect-in-Place note is to differentiate between trail distances needing widening to 5’-0” and those trail areas which already meet the 5’-0” width, as well as to pre-determine how much square footage of native vegetation areas will be impacted (and reported within the Environmental Documents for the project). * In all areas where the existing trail was less than the 5’-0” designated width (to be attained at the completion of the project), and residual grading must occur on either one side or both sides, the limited displacement of existing vegetation (some of which will be native vegetation, while substantial growth is actually invasive weed material) will be necessary. These designations are being called out by the project’s botanist team, which have been on-site during clearing and grubbing activities to help guide where the removal of plant material has the least impact on native vegetation. During project design, the design team made anticipated calculations of the amount of (SF) area projected for disturbance; and the actual areas are being calculated by the naturalists as the project progresses. * For discussions regarding clarifications on the BMP’s, please communicate with the City Engineering staff (Fabian?) Hopefully this information will be helpful.

See below and attached. I know Ryan and I talked briefly about the Lee Paulson letter early last week but now that we’ve got a federal agency asking about it I think it may be better for me to get official text from the City and/or Dick regarding the project design and width. I do not want to misstate anything from my perspective and cause any additional questions. Can one of you send me something back, or at least confirm that the project is being implemented as designed in Dick’s plans and that there haven’t been any major changes? I can throw the latest permanent impact acreages into my response back to her. I am not sure about BMPs but the photos certainly don’t show any that I can see (such as silt fencing, etc.). In many cases this is not a big deal because there aren’t many appreciable slopes down the sides and it is generally very gradual and flat-ish but it is probably most relevant in the switchback area where the illegal trail is being cut off, as that is a steep grade and there are clearly piles of sediment coming down the sides. I looked in the IS/MND and saw that the project is required to have a SWPPP with applicable BMPs. Do we have the SWPPP and do we know if the contractor has implemented any BMPs from it, at least when rain is forecast? This is especially important this week because there is rain forecast in a few days. I’m currently seeing about 1.25 inches forecast between Thursday and Sunday, with the bulk on Thursday. Did they put any BMPs in place for the prior rain days? I think these were days when the biologists weren’t around anyway. Obviously the sooner I can respond the better, because right now USFWS is clearly on our side by the fact that she’s reaching out just to me personally and in such an informal manner. I don’t want to leave her waiting too long before I get back to her. Btw note that the drone photos include multiple shots of that v-ditch, which will probably trigger a response from CDFW. Thanks very much!

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.

We were grateful for Ryan's attention and help. This morning, I sent an email request for information to Ryan. His automatic email message states he is out of the office until December 5th. Will you please help me obtain this information today or tomorrow? I would like to come in to observe these records if they cannot be assembled quickly and sent to me via email in PDF format. I request this information PDF to this email address, in any case. PUBLIC INFO REQUEST I request all forms of communication and correspondence between the City of Diamond Bar and anyone in the United States Fish and Wildlife agency, regarding the presence of the California Gnatcatcher in the city and on the Canyon Loop Trail. Specifically, I wish to learn HOW the determination that an Incidental Take Permit was not necessary, occurred. I appreciate the City's response and transparency in this matter. Thank you.
