Joel,
I dug through all the files that we had. All I could find was a part of a report that Reed Engineering did for Coffman. It is attached. I have called Ron Reed with Reed Engineering
and asked for the complete report. He said he would email it to me. When I receive it, I will forward it to you. I am not sure if it what you are looking for, but it looked promising
and may help us with Alpha and some of the other taxiways.
Thanks,
Clay Barnett, P.E.

Nancy / Clay,
Per Frank’s inquiry, do you have any soil borings or geotech reports for the shaded areas in the attached graphics? Except for the north RSA, I think the only borings we
have are through pavements, but I will take a look. As I mentioned to Frank, we hit a lot of rock when the AWOS was installed; I think it’s definitely a concern.
Regards,
Joel

Joel:
As we refine our RSA grading and drainage design, especially on the west side, I am becoming concerned that ditch excavation may encounter rock. Without soil borings, we can’t estimate
the rock excavation. Do you have old geotechnical reports and/or soil boring logs for the areas shown on the attached exhibit?
