	==238.3.31 Land Survey Ties==		==238.3.31 Land Survey Ties==

	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. The project development engineer is advised early in the survey concerning the location and number of corner monuments that need to be re-established or witnessed so this work can be completed prior to submittal of plans to ~~the~~ [~~http~~://~~wwwi~~/~~intranet~~/rw/ Right of Way ~~Division~~].

	Survey personnel are in an excellent position to promote good public relations for MoDOT. They are usually the first representatives of the department to contact people affected by proposed highway improvements. Therefore, it is the district survey party chief’s responsibility to ~~insure~~ their personnel present a good appearance at all times. Additionally, the district survey party chief acquires general information concerning the proposed improvement to inform people encountered during the survey.

Line 349:		Line 349:
	An extreme high water elevation is obtained for the centerline profile, either by observation of visible high water marks or by conferring with maintenance personnel or local residents. When sufficient information is available to make an accurate determination, extreme high water elevations are obtained for each of the valley sections. The location and elevation of the high water elevations are included in the survey notes while the location is tied to the survey centerline or base lines. The best procedure is to obtain information from local residents and then confirm this information by observation. Quite often local residents may exaggerate, or the high water elevation remembered by them will be far beyond the flood frequency to which the structure is to be designed. Particular care is exercised in obtaining this information since it is used as the basis for laying out the proposed structure. If any doubt exists as to high water marks reported to the survey party, give location and elevation of all such marks and in every case give dates of occurrence. Survey personnel are encouraged to mark and record, for future reference, high water elevations for at least all major streams during or immediately after floods.
