Hi Joe,
A lot of work was put into the updated Dry Utility Plan. Our plan review indicates that the installation of the proposed
ductbank, and the direction drill, should not interfere or conflict with the District's water facilities.
We noted that the ductbank was moved out into the street in 234t" so that we now have roughly 7' between the 8"x 4"
meter tee and the ductbank (or roughly 5-1/2' between the block and duct trench). The separation between the
restrained water and the ductbank is acceptable. Also no issues with the proposed WA-Ductbank crossings or the
directional drill WA -conduit crossing.
It does appear that a small portion of the ductbank has already been installed parallel to 99. Rather than along the south
side of the proposed sidewalk as previously proposed it now runs through the planter between the walk and the
curb. The installed ductbank therefore crosses the two FH runs and we assume that this work was completed without
issues.
Thanks
Peter

Peter,
The City has been reviewing the dry utilities plans in detail and we've had a couple rounds of revisions. Attached are the
latest plans, which show the ductbank out further in 234t" per their request. They've also requested the ductbanks have
5' of cover in 230 (and anywhere in the ROW where they're not already installed).
This pushes the ductbanks deeper and further away from the water main connections, which have been installed. We
would appreciate your review and approval (or comments) on the proposed layout.
Thanks in advance and please let us know if you have any questions or comments. Thank you,
Joe Taflin P.E., LEED AP

Good Afternoon Everybody,
I just talked with Cody at OVWSD and the water -duct bank configuration as proposed below will be acceptable to the
District.
Let me know if you have questions.
Thanks

Hi Caitlin,
We looked at the typical profile info and typical sections shown on the Dry Utility Plans. Based on earlier watermain
pothole info (unrelated to this issue), typical duct bank depth, and the horizontal alignment, it looks like there would be
a conflict with the watermain, especially with the thrust blocks behind the tees.
However, in coordination with Joe Taflin we proposed a solution that, if acceptable to the District, would also need to be
provided to Frontier/SnoPUD for approval. What we recommended is the following:
- Push back the duct bank by a foot and reduce ductbank cover by about 7". This would bring the elevation of the
bottom of the ductbank to the crown of the WM.
- Most of the thrustblock could be placed against undisturbed soil. Also, there would be some separation to the
edge of the CDF ductbank to allow work on the tee if needed.
- To more than make up for a slightly less optimal thrust block configuration, the fittings and pipe should be
restrained. See below screenshot for illustration.

PACE to get buyoff from the District on the proposal that is described below.
Once District confirms that propose is acceptable, Navix/Developer to provide the proposed change to Frontier and
SnoPUD for their approval.
Navix/Developer will then need to provide direction to the utility contractor for them to restrain pipe and fittings for the
connections. A field change that is noted in the redlines should be enough. Finally, as soon as we have confirmation

that Frontier & PUD have approved, and that the Contractor has been notified of the change, we can provide our formal
approval to the City.
Thanks
