The following information relates to the use of an arc boundary to define the horizontal extent of a parcel.

### Arc boundaries only for horizontal extent of parcel

An arc boundary may be used to define the horizontal extent of a parcel boundary [r 6.5(a)(ii)] but not the vertical extent.

### Size and location of arc line expressed as a chord bearing

The size and location of the boundary is normally expressed by a chord bearing, arc distance, and radius [r 9.6.14(a)(ii)].

### Associated boundary points of arc boundary

Each arc boundary terminates at an associated boundary point as illustrated in Figure 1 above.
