Excerpts from Onsite Inspector’s Weekly Report: August 6, 2009

posted in: WRIA 11 Nisqually | 0

Every week I will post highlights from the on site inspectors report. The Inspector is taking daily notes on progress, difficulties, etc.  At the end of each construction week (Mon- Thurs), these notes are forwarded to the project manager in the form a summary.

Test pits were dug on both Tuesday and Wednesday of this week with ground water not being encountered until depths of between 6.5 and 11.5 feet were dug EXCEPT near Hwy 7 which encountered water at 4.5 feet.. Test hole photos were taken and Mark the operator laid out ‘scoops’ side by side by side with at- depth materials, showing turf, alluvium, sandier mix and then bluish clay. We were pleased with the groundwater so deep.  It appeared as if the excavator had NOT been steam cleaned recently and I mentioned this to Ben.  Prior to channel construction it’s a requirement of the permits.

A critical reference photo is WHERE the new channel will come into the existing one.  Since the control –verified staking is NOT yet installed, we agreed next mid-week would be good for a site visit for completing the photo point establishment.

His main needs are photo opportunities for tracking:

CHANGES IN HYDROLOGY

CHANGES IN VEGETATION

STABILITY OF NEW CHANNEL

CHANNEL FORM / RESPONSE ..is it incising? Staying put?

TYPICAL LWD STRUCTURES  AND X-SECTIONS
