Note the horizontal and vertical datums used by the project on the Dimensional Control Plan, along with the grid to surface scale factor if surface coordinates were used. Show and label local survey control points clearly on the plans, along with corresponding northing, easting, and Z (elevation) coordinates.
All work and materials shall be in accordance with the City of Grand Prairie Construction Standards and Specifications and the North Central Texas Council of Governments (NCTCOG) Public Works Construction Standards. Should a conflict be found between publications, the City of Grand Prairie Standards and Specifications shall take precedence. In the event that an item is not covered by the City of Grand Prairie Construction Standards and Specifications, the most current edition of NCTCOG Public Works Construction Standards shall apply. Reference to any other documents contained in the project specifications shall be made to the latest edition of such documents, and shall include the referenced specification in its entirety.
- Note that if civil engineering plans are submitted for review prior to site plan/plat approval, changes to the plans may be required as a result of site plan/plat approval conditions.
- Beginning October 1, 2017, should a construction project require the interruption of traffic on any existing roadway, or the closure of any shoulder or alley, a detailed traffic control plan shall be provided in accordance with the Texas Manual on Uniform Traffic Control Devices (TMUTCD).
