Mr. Larry Davis City of Coppell Post Office Box 478 Coppell, Texas 75019 Re: City of Coppell Village Parkway Pump Station Additions Dear Mr. Davis As you requested, we have completed the As Built survey of the driveway turn-out constructed by NTMCC with the Village Parkway Pump Station Additions project. This survey was conducted to verify the finished grade elevations of the constructed driveway. As shown on the enclosed exhibit, the finished grade at the end of the drive way is high (Survey Point 20) and a section of the driveway approximately 25 feet in length is flat (Survey Point 14 to Survey Point 21). In order to correct the problem, we recommend NTMCC grind or remove a section of the driveway from survey point 14 to survey point 20 until the finished grade is in conformante with the project plans or positive drainage is achieved. We are available to discuss this further at your convenience. Sincer Enclosure J:\Coppell\94156~L\Const~Driveway. doe EXIST. ~ ,.d"' PVMT. ~ ~.y,/ 39.42 L.F. EXISTING CURB '5_,~.:~/'' 32 L.F.
