PROJECT REVIEWER: Zelin Canchola,
TDOT Review Section

DOT Review Section has reviewed the PIA Plan for Traffic Engineering. The proposed striping and signing is acceptable. However the following changes/redlines is required for approval:

1. Page 2 of 23. Pavement marking notes, # 2 Change reference from Pima County to city of Tucson. Replace "Pima County pavement marking supervisor (520 740-2624) " with "City of Tucson Traffic Engineering (520 791-4259)

2. Page 13 0f 23. Add markings and signs to the proposed southbound right turn lane from Houghton Road to Drexel.

3. Add quantities for striping and signs on the plan.


If you have any questions I can be reached at 837-6659 or zelin.canchola@tucsonaz.gov
05/16/2017 LPETERS2 DOT PERMITS & CODES REVIEW Denied I have reviewed this plan and have the following comments:

1. On sheet 9 - Detail C - The paving detail mentions a rolled concrete mix design. Is this just typicla concrete paving? What is the psi on this proposed concrete?
2. On sheet 9 - - Detail C - This calls out local streets and residential collectors. It appears that the project is dealing with Drexel only, which I would think would be the reisdential collector. Is this correct?

No further comments.
