(A) Primary horizontal control points will be used when surveying each tract being subdivided. These primary horizontal control points must be established by using centimeter-grade accuracy Global Positioning System devices, procedures and methods that meet the state’s standards. New primary horizontal control points must be established and monumented for each subdivision.
(B) Primary horizontal control points shall be tied to at least one National Geodetic Survey mark and the point will be identified as the datum point on both the hard-copy and digital plat submittals.
(C) The minimum number of required primary horizontal control points (reference corners) is based upon the overall plat size in acres as described in Table 153.1632(A) of this chapter.
(D) The plat must include the X-Y coordinates for each of the primary horizontal control points, and consistent and appropriate bearings between each of the primary horizontal control points. These primary horizontal control points will be provided in NAD83 United States survey feet, State Plane Coordinates for the state.
(E) All primary horizontal control points shall be permanently identified with monumentation set to the state’s Board of Land Surveyor’s minimum standards.
