Ryan,
We may be able to send along some of the monitoring reports to show him progress. I can ask Endemic about photos of the water diversions and gabions but otherwise I don’t have a diagram
of locations other than maybe Dick’s original blueprints.
I have some availability next week if we wanted to try to meet with him in person and I’m generally not available at all the week of November 21.

Good afternoon Ryan,
Thank you for providing this material and elaborating on the description of the drainage crossings. Would you happen to have any photos of the crossings that have been installed? Or
photos from the ground of where they are intended to be installed and where the gabions are intended to be installed?
Water quality and erosion (as well as impacts to all plants and wildlife that may be present) are a concern. We want to make sure that this is being addressed. I’m sure that the City
wants to protect the environment too and the site for the public and wildlife to enjoy. If you have any status reports on how the work is going or can show me additional photos of how
the work has been progressing, that would be greatly appreciated.
I think it may be beneficial to do a site visit and walk the trail with you and the City when we all have an opportunity. I have some other site visits scheduled this week and next,
but hopefully we can set up something soon.
Please provide this additional material and we can continue to coordinate on this project. Thank you for your time and assistance on this matter.
Warmly,
Fritz Rieman

Hello Fritz,
Thanks for your call earlier and I apologize for the misunderstanding with the project description on the website. I have included some selected photos of the southern loop of the trail
where nearly all of the work will be conducted, as well as a kmz showing the trail loop and the east and west ends of the widening/improvement along the southern loop. The northern
loop will be largely untouched other than one new bench area where there is already existing disturbance; the northern loop is an SCE access road for some transmission towers alongside
it so the road is already quite wide on the north. On the southern loop there is trail widening along most of the length that I’ve highlighted as well as some isolated occurrences of
gabion wall installations, stair installations, and new benches. The “drainage crossings” referred to on the City website refer simply to diversions to take rainfall off of the trail
during rain events. As you can see from the kmz and if you manipulate your viewpoint in Google Earth, the southern loop is at the top of the slope. There is nothing above it and no
waterways crossing through it; it is completely dry with no possibility of water unless it rains due to its position at the apex of the slope. The only waterway in the project area
is the one down at the bottom of the canyon between the north and south loop trails, which will not be touched and will not have any construction anywhere near it.
Please let me know if you have any further questions or if you’d still like to meet on-site to verify in person next week; the City has also expressed interest in attending if so.
Thank you!
