(1)(a) The corners of lots, tracts, other parcels of land, aliquot corners not described in subsection (4) of this section, and any line points or reference points which are set to perpetuate the location of any land boundary or easement shall, when established on the ground by a land survey, be marked by reasonably permanent markers solidly embedded in the ground.

(b) A durable cap bearing the license number of the professional land surveyor responsible for the establishment of the monument shall be affixed securely to the top of each such monument embedded pursuant to this subsection (1).

(3)(a) If the monuments or markers required by subsection (1) of this section cannot practicably be set because of steep terrain, water, marsh, or existing structures, or if they would be lost as a result of proposed street, road, or other construction, one or more reference monuments shall be set.

(c) Reference monuments shall be set as close as practicable to the true corner and shall meet the same physical standards required to set the true corner.

(d) If only one reference monument is used, such reference monument shall be set on the actual boundary line or a prolongation thereof, otherwise at least two reference monuments shall be set.

(5)(a) The top of the monument for any corner required by this section which is within the traffic area of a publicly named dedicated or deeded street, road, or highway shall be placed one-half foot below the roadway surface.

(b) If the roadway surface is pavement two inches thick or greater, the monument shall include a monument box the top of which shall be set flush with the surface of the pavement.
