PRECONSTRUCTION

Field Witnesses

Be sure to contact the Region Surveyor by writing prior to work commencing for permission to not use straight line witnesses(821.01.B.2). All objects used as witnesses to reestablish the point shall not be marked as remove or adjust in the plans and will be outside of the potential construction activity & utility relocation limits. The witnesses shall be field measured and turned into the Region Surveyor before construction(821.01.B.1). If the Region Surveyor agrees to not using straight line witnesses the points must still be verified by witnesses and not set by coordinates alone.

CONSTRUCTION

Land Corner Recordation Certificate

Before recording the LCRC’s for all PLSS corners and alignment points a draft of the Land Corner Recordation Certificate must be submitted to the Region Surveyor for review, prior to recording(821.01.B.4). PLSS corners that have not been re-monumented still needs to be recorded and a comment in Part B stating, “Found before construction”. Notes if available from the Region Surveyor should also be included in the LCRC, along with the MCS coordinate values of the points. The observation date, Datum and Epoch will be listed with each coordinate value. For all points marked as Preserve or Protect a table of all corners shall be submitted to the Region Surveyors.
