Bill,

 

            Just a heads-up that TAS has a little matter of drainage still to resolve along Taxiway Sierra. The approved plans included a concrete flume in the grass area between their
hangar and the taxiway, which for some reason they did not build. I’m not certain it’s a big problem, but it does need to be addressed, which is what the attached is about. In spite
of the below e-mail being addressed to me, I have no intention of replying … Clay is the P.E., and I’m happy to stand back and let him do what he does. (Thanks, Clay!)

Subject: Proposed Grading Modifications

 

Clay and Joel,

I have attached a PDF of a proposed grading plan for the area between Taxiway Sierra and the existing parking area at Turbine Air.  There is positive drainage from the taxiway to the
parking areas if we can allow a straight grade between the two locations (slopes are provided).  On the west end of the property near the existing inlet, we are proposing to leave the
grading “as-is”.  On the east end, we are proposing a swale with a slope of 0.5% to drain this area to the parking area.  Please review and let me know if you have any questions.  As
soon as you can let us know that this is acceptable, we will prepare a formal plan submittal so that the contractor can complete the work.

 

Thanks

Steven R. Homeyer, P.E.
