	The [[238.2 Land Surveying#238.2.18 Location Survey Plan\|location survey]] includes ties between the highway survey alignment and corners of the U.S. Public Land Survey System. A legal land survey corner is defined as one that is witnessed or monumented by a professional land surveyor. Location survey plans, with certification and seal, of these witnessed or monumented corners and reference ties, are filed with the county recorder of deeds. All physical corners of record within the right-of-way corridor must be referenced. The appropriate state land surveyor form is also completed by the surveyor for submitting to the State Land Surveyor. The survey must be tied to all physical corners of record for each ¼ section through which the survey passes. Ties must be sufficient to ensure that at least one public corner per section, and all other pertinent public corners are referenced to the highway survey alignment. The ties between the highway survey alignment and the land survey corner monument include the station and angle at the highway survey alignment, and the distance to the monument. Bound notebooks or data collectors are used for recording the field notes and observations. The description of the land survey corner monuments must be complete and definite; e.g., 4" x4" Limestone, 1/2" Steel Pin, or 1" Axle, S 1/4 cor. of Sec. 6, T56N, R14W.

	Existing ground profiles are to be parallel to the roadway, unless the [[media:747 Bridge Survey Location Request.docx\|Bridge Survey Location Request]] provides additional guidance. One profile at the centerline of the roadway and the other two offset beyond the outer extents of the roadway fill and ditch lines on each side. The offset profiles are obtained at a distance sufficient to provide a true representation of the terrain features; profiles in ditches or on existing roadway fill are not representative and should be avoided. Where the centerline of the roadway does not coincide with the survey centerline (e.g. surveys along the centerline of the median for divided lane facilities), an offset profile along the centerline of the roadway is required. Where dual structures for divided lane facilities are separated by more than 64 ft., offset profiles are obtained on each side of each structure. These profiles cannot be taken from cross sections.

	In order to provide the best possible structural design, it is imperative that the bridge survey be completed as fully and accurately as possible. The completed [[media:747 Bridge Survey Location Request.docx\|Bridge Survey Location Request]] form should be used to provide guidance on survey activities (see [[:Category:747 Bridge Reports and Layouts#747.1 Bridge Survey Location Request\|EPG 747.1 Bridge Survey Location Request]]). Consultation with the Bridge Division early in the project to answer questions or resolve issues is encouraged. Bridge surveys require the following minimum information:		In order to provide the best possible structural design, it is imperative that the bridge survey be completed as fully and accurately as possible.

	Water surface profiles are typically required for drainage ditches to help determine the slope of the stream flow. Water surface elevations should be taken at least two locations on each side of the crossing at 100 ft. intervals from the roadway centerline, but may be omitted if flow in not present. The need for a water surface profile will be indicated on the [[media:747 Bridge Survey Location Request.docx\|Bridge Survey Location Request]] form.
