HomeMy WebLinkAboutRe_ Canyon Loop Trail (5)Good morning,
I'm out of state this week but I believe we have the monitor scheduled for one day this week and that should be the end of ground disturbance. Thanks,
Ryan

Understood thanks But please note the biological monitors are there just for the biology our services are needed for all ground disturbances per the compliance conditions of the project
. That said if you are confirming ground disturbances have ended then we are ok.

Good afternoon everyone. Danny Daher with DD Systems has confirmed in writing all ground disturbance has ended and if for any reason that changes in the future, we will reach out
to the Kizh team.
Please note the team of biologists will periodically check it on-site, but thanks again to Armando for his support.

Hello Ryan,
Can you confirm the status of ground disturbances. Armando campos was told All ground disturbances were completed is that correct?

Good Morning,
Just a friendly reminder, we will meet this Monday, October 24 at 9am at the same location. DD Systems is currently staking the trail and all grading/ground disturbance will commence
after the 9am meeting Monday. Please let me know if you have any questions.
Thank You,

Good Afternoon,
Thank you all for your time this morning to chat briefly about the project. I just wanted to provide this email which includes everyone from the meeting in case you needed a point
of contact. To reiterate, all ground disturbance will begin Monday, October 24 per DD Systems, Inc.
Please note we will meet each Monday at 9am for weekly updates and previous weeks’ reports are also due electronically each Monday morning.
Thanks Again,

t. 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.
Best,
Dick Fisher
