The following information relates to recording a stratum boundary, and its related witness marks and PRMs where required, in a CSD.
A Diagram of Survey must describe the spatial relationship between the stratum boundary and the other boundaries [r 9.6.10]. This information must meet the boundary accuracy standards and boundary witnessing standards.
Where a stratum boundary is used, the required witness marks and PRMs and vectors between them (refer to rules 7.3.1(d), 7.3.2, 7.4.3(d), and 9.6.10) must be electronically captured and depicted in Landonline generated diagrams.
Most of the information relating to a unit CSD or cross lease CSD is depicted on plan graphics. On these CSDs the Diagram of Survey will include an additional Landonline generated diagram of the required witness marks and PRMs and the vectors between them.
Where a stratum boundary is the surface or the bed of a water body, the Diagram of Survey and Diagram of Parcels must describe the legal boundary that is the stratum boundary [r 9.6.7(c) and r 10.4.5(c)]. Examples are '80 m contour (Moturiki Datum)' or 'bed of lake'.
Note, the requirement for a legal description must not be confused with the physical description although, in some cases, they may be the same.
