We believe that TNP is using a different coordinate system than we use, and that is causing this discrepancy. If you are aware of this, and are doing it intentionally to make our drawings work with the SH 121 widening project, then we can apply some sort of conversion to our data collection to rectify the situation. If this is an inadvertent use of a different system, then we will ask you to correct the drawings to shift your work into the appropriate coordinate system. Keith Marvin, P.E.
