Ties to Public Land Survey Corners
Idaho Code 50-1304 (g) requires survey ties to at least two (2) Public Land Survey corner monuments in one (1) or more of the sections containing the subdivision, or in lieu of Public Land Survey corner monuments, to two (2) monuments recognized by the County Surveyor.
In addition, Ada County Code 8-6-4-3(g) requires that the plat show at least two (2) primary control points, officially recognized by the County Surveyor and ties to such control points. Primary control points must be Public Land Survey corners or officially recognized corners. Corner perpetuation and filing recording instrument numbers shall be shown.
The definition of “Public Land Survey corner” appears in Idaho Code 50-1301(9), Plats and Vacations, 55-1603(10) Corner Perpetuation and Filing Records, and 55-1902(8) Records of Surveys laws. By definition, a “Public Land Survey corner” is “any point actually established and monumented in an original survey or resurvey that determines the boundaries of remaining public lands, or public lands patented, represented on an official plat and in the field notes thereof, accepted and approved under authority delegated by congress to the U.S. General Land Office and the U.S. Department of Interior, Bureau of Land Management”.
Also, the definition of “controlling corner” can be applicable as to what is shown on the plat in some cases. A "property controlling corner" for a property is a Public Land Survey corner, or any property corner, which does not lie on a property line of the property in question, but which controls the location of one (1) or more of the property corners of the property in question.
Public Land Survey corners are interpreted as meander corners, quarter corners and section corners (corners set in the original government surveys), and are the corners used by the Assessor’s office for tax parcel mapping purposes. While the County Surveyor has accepted corners other than public land survey corners, the corners are not accepted for plats unless they have a Corner Perpetuation and Filing Record filed on them.
· Are there two Public Land Survey corners shown? Only Section corners or Quarter corners. Anything other than this gets passed on to the PLS review.
· Are CP&F’s shown for the corners?
· Are the corners labeled with the sections, and are the sections labeled on the correct side of the line?
· If corners are on a township and/or range line, is the township and/or range line labeled?
· If there are sectional corners shown that are not Public Land Survey corners and are used for controlling corners, are they labeled?
· If a corner is described in the Certificate of Owners, is it shown on the plat the same way? If it is described in the Certificate of Owners as the SE corner of the NW-1/4 of the NW-1/4, is it labeled on the map as the SE Corner of the NW-1/4 of the NW-1/4, instead of the NW-1/16 corner?
· Do the monuments shown match the legend, or are the monuments labeled with the type of monument and LS number? Do the monuments shown in the CP&F match what is shown on the plat?
· Do the bearings and distances match previous dimensions of record for this line? If they do not, are the record distances shown?
