PURPOSE: This rule prescribes the type of monument to be installed to preserve the position of the United States Public Land Survey Corner.

1. (1) All corner witness and reference monuments shall be permanent monuments of a type providing a degree of permanency consistent with that of the adjacent terrain and physical features. Monuments will meet the requirements for a permanent monument in accordance with 4 CSR 30-16.060.
2. (2) In such cases where the placement of a required corner monument at its proper location is impractical, it shall be permissible to set a reference or witness monument or mark near that point, and if such reference monument or mark is set, its location shall be properly shown on the documentation.
3. (3) All monuments shall be marked and designated in accordance with 4 CSR 30-17.060. The precise position shall be marked by a point, cross, or appropriate symbol on the monument.
4. (4) Where possible, four (4) reference ties (distance and/or direction) to durable objects will be made to provide the means for relocating the marked corner if the monument is disturbed. Durable objects include, but are not restricted to: house corners (fully describe), marks on concrete structures or pavement, marks on ledge or bedrock, trees, additional permanent monuments, fence posts, utility poles, and crosses on curbs.
5. (5) In some special cases where an existing monument is found and it is deemed appropriate to preserve the monument in its original location, a reference or witness monument may be installed nearby.
6. (6) At locations where a stone, iron pin, pipe or other monument is to be replaced by a permanent monument, the existing monument will be removed and buried or placed alongside the permanent monument. If there is an “X” or other mark on the old monument, it should be buried facing down or on its side so as not to be confused with the permanent monument.
