George,
Attached are the revised TCP along with the detour plan. I don't have the luxury of being able to draw
anything to scale. The only thing I can work from is google maps. So the locations of existing topo are
estimated. What you have seen is a graphical representation of the traffic control. Everything is laid out based
on distances per MUTCD. If a sign or arrow board ends up in a driveway then it is shifted to avoid the opening.
This also goes for the area of construction, yes phase II looks small graphically but what is shown is the general
area of construction. What it comes down to is that I am free handing the existing topo and doing a lot of
guessing with very little data to work from. The topo will never be perfect without a detailed survey.
If the city wants to perform densities then the project could be sitting idle for three days while waiting on the
proctor. The way we operate is to remove and set up as quickly as possible. Removals on phase one should
take a max of two days more than likely one day. Then we set up and pour. We will be ready to set up and
pour before densities are ready to be taken. Wasn't it discussed that there is a possibility of proof rolling
instead of taking densities?
Thanks

Lee,
Please review the attached joint plan. We would like to see Keyway joints throughout the stamped areas.
Because the south median nose does not have enough room to fit the standard detail then we will just replace
the nose with a std 6" curb like what is out there today.

The geotech has not performed a proctor test yet. Once you are onsite and they are able to pick up a proctor
sample it will take them 3 days to complete.
On the tcp pans you gave me at the meeting, I have a few comments.
1) You are showing arrow boards and signs placed in driveways both north and south Denton Tap. Please keep
these out of the driveways.
2) Noticed that your map is not to scale. You have a 150' taper area that looks like it is longer than the 295'
transition area.
3) Show the road closure signs on Sandy Lake at the driveway openings both east and west.
4) Phase II, do not show right turn on Sandy Lake. We don't need people to be slowing down to turn and
backing up traffic more.
5) You will need roughly 60' in middle (50' dia +5' each side). Width of phase II construction area seems too
small.
Also, please don't forget about pedestrians.
Thank You, George

George,
Wanting to see where we stand on obtaining the following information on the Denton Tap & Sandy Lake Paver
replacement project.
Joint Layout plan
Detail on median nose replacement
Does testing lab already have a proctor on the project and ready to take densities.
I am working on the TCP for the detours and hope to have it complete today.
