1519 Surveying, LLC (1519) completed the schematic design survey for approximately two (2) miles of Farm to Market Road 428 and County Road 55/Glendenning Parkway, from 1,000 feet west of Dallas Parkway to 1,000 feet east of SH 289 (Preston Road), for the Texas Department of Transportation (TxDOT). 1519 established four (4) permanent horizontal and vertical control monuments and set secondary control points along the proposed route. 1519 ﬁeld crews recovered property corners and right-of-monuments and 1519 oﬃce personnel completed the right-of-way veriﬁcation map for the proposed route. Field crews also surveyed the locations of drainage structures, utilities, signs, and creeks within the existing right-of-way.
1519 completed the aerial mapping of the proposed route, which included seven hundred (700) feet on each side of the proposed alignment. The planimetric (2D) features were extracted by processing the ortho imagery obtained from a ﬁxed wing UAV ﬂight, and the .tin (3D) data was created by using the Lidar point cloud data gathered from a helicopter ﬂight.
Deliverables included signed and sealed control sheets, imagery and point cloud ﬁles, and Microstation ﬁles completed to TxDOT standards.
