This article relates to the information that is required to be included in a CSD Plan under rule 9 including information on PRMs, occupation, and how to deal with unofficial boundary marks.
The CSD Plan holds survey information designed for survey users. The information is necessary to provide a record of the survey as lodged and certified and to enable surveyors to use this information to re-establish the boundaries in the future.
Every CSD must include a CSD Plan [r 8.1(a) and r 11.3(a)].
This includes CSDs without survey information for unit and cross lease developments where the CSD plan and the Title plan may be quite similar. The majority of information will be aspatial information depicted on plan graphics.
A CSD Plan consists of both diagrammatic and non-diagrammatic information. The diagrammatic information must be depicted on a Diagram of Survey [r 9.6 and r 11.4.1].
In a CSD Plan, information not required to be presented diagrammatically includes information about:
- existing CSDs used for the survey [r 9.1(a)] (note, the land district reference is required for CSDs with a number less than 300 000),
- the location and description of PRMs [r 9.1(b)] (refer to Information for permanent reference marks below),
- horizontal and vertical datums used in the survey [r 9.2] (refer to Datum information in a CSD),
- adopted vectors, bearing adjustments, and the type of vectors [r 9.3] (refer to Recording vectors and dimensions in a CSD)
- adopted boundaries, the survey class, and the description of a water boundary [r 9.4] (refer to Recording class of survey in CSD plan and CSD diagrams must include physical description), and
- occupation and physical features [r 9.5] (refer to Occupation and physical features below).
Non-diagrammatic information may be in Diagram of Survey
In a CSD Plan, the surveyor can choose to include non-diagrammatic information on the Diagram of Survey. Its inclusion on the diagram satisfies rules 9.1 to 9.5.
A CSD Plan must include the description and location information for a PRM where that information is not already recorded in the cadastre [r 9.1(b)]. Historically this information was often recorded in a location diagram.
While the rule does not specify content, the information could include:
- the relationship of the mark to physical features and structures in close proximity,
- the mark's relationship to ground level, and
- a description of any material used to stabilise the mark (eg concrete).
It is recommended that this information is captured in the Landonline 'mark detail – description' field. This enables the information to be displayed on the Diagram of Survey and to be viewed with the object information tool in the spatial window. It will also appear in the 'mark and vector' schedule of the CSD plan.
Alternatively, this information can be provided on a location diagram in conjunction with the 'occupation diagram' that gets incorporated into the 'CSD plan'.
Descriptions for geodetic control marks included in the geodetic database satisfy rule 9.1(b).
Meaning of extent of occupier's use of land
A CSD Plan must include occupation information [r 9.5(a)].
If a field note is used to depict occupation, this note must be included in the CSD as an 'occupation diagram' so that it becomes part of the CSD plan.
The requirement to provide occupation information applies both when the extent of occupation is contained inside the parcel under survey and where the land used extends beyond the parcel boundaries as shown in Figure 2 below.
Historically, occupation has been interpreted as the physical objects in close proximity to a boundary rather than the extent of an occupier's use.
To satisfy rule 9.5, the information must now include the nature and age of the feature (fence) and its relationship to the parcel boundary.
When occupation information is required
The longstanding practice of including occupation information only for new boundaries and in some cases only where occupation was within 1 m of a boundary, no longer applies.
The requirement to include occupation in a CSD Plan applies to all:
- new primary parcel boundary points defined by survey on an existing boundary [r 9.5(b)(i)]. Line pegs are an example.
- existing points being marked or remarked [r 9.5(b)(ii)]. This applies to both primary and non-primary parcels.
- existing or new boundary points required to be defined by survey because of conflict or when there is the potential for another party to have an interest in the boundary location [r 9.5(b)(iii)].
Note that in this case the occupation must be in the form of a diagram [r 9.5(b)(iii)] to enable a layperson to easily interpret the relationship between the occupation and the boundary.
Relevant occupation can be inside or outside the parcel under survey.
OP no record can be occupation
If an old peg is not used as a boundary mark on the new survey, it must be recorded in the CSD Plan as occupation information [r 9.5(a)(iv)] (refer to Old mark no record). While the details to be provided are not specified, the information could refer to the mark being unofficial and having the appearance of a boundary mark.
The information required by rule 9.5(a)(iv) and mark position may be depicted on the Diagram of Survey as an alternative method of complying with this rule.
