Hi Sarah,
As an alternative to the method discussed in today’s meeting for adjusting the water lines at the 30” storm locations in the intersections, Daphne has provided below some suggestions that I believe may save additional time in the schedule. I agree with her suggestions below.
Please let us know your thoughts.
Thank you,

Subject: Molalla - 30" SD and Waterline Connection Options
Hi Jennifer,
Thanks for discussing the waterline connections at the 30” SD crossings. A suggestion for the Contractor to resolve the conflicts in these locations is to make the waterline connections and construct the new waterlines all the way to the locations of the proposed tee and valve.
For example, on 2nd Street, the Contractor could connect to the existing 6” waterline, go under the 30” SD, and continue the new waterline to the proposed 10”x6” tee and 6” gate valve. For the temporary condition, they would close the 6” gate valve and install a thrust block behind the tee. They would come back later and install the proposed 10” waterline in the north south direction and connect to the tee.
It is possible to remove the horizontal jog(s) if the Contractor removes the section of existing waterline along the existing water line alignment.
The suggestion of constructing the segments of waterline to their proposed valve and tee locations may be preferable for resolving the conflicts with the 30” SD.
I am available to review each intersection in more detail with the Contractors if that would be helpful. Tomorrow, I am not planning to be in the office but I will check email and respond as I am available.
Thanks,
