Frank, Attached is a new concept from the folks over at Homeyer. I am concerned about grass areas that are flatter than 1%. I am not sure what the FAA Circulars advises on this. Could you review and let me know if you have any comments? Thanks, Clay Barnett, P.E. Town Engineer Town of Addison 16801 Westgrove Drive Addison, TX 75001-2818 Office: (972) 450-2857 From: Steve Homeyer [mailto:shomeyer@homeyer-engineering.com] Sent: Friday, December 17, 2010 1:30 PM To: Clay Barnett; joel.jenkinson@addisonairport.net Cc: Steve Homeyer; Ben White 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.
