Part 3 - Boundaries

Question 1

7 Right-line boundaires

A right-line boundary must…

Answer 1

• follow the shortest distance between 2 boundary points

Question 2

8 Arc boundaries

An arc boundary must…

Answer 2

• follow part of the circumference of a horizontal circle

Question 3

9 Irregular boundaries

An irregular boundary must…(2)

Answer 3

• follow an irregular line

- not be used unless expressly allowed by these rules

Question 4

9 Irregular boundaries

An existing irregular boundary on a new primary parcel must be converted to 1 or more right-line boundaries unless…(3)

Answer 4

• it is accepted in accordance with rule 15 (acceptance of boundary)
• it is part of a new primary parcel that is either:
  
  • over 20ha and comprises more than 80% of the existing primary parcel being extinguished
  • over 100ha
• a former water boundary

Question 5

10 Water boundaries

A water boundary must follow the landward margin of… (3)

Answer 5

• a river/stream bed
• a lake bed
• a tidal area

Question 6

10 Water boundaries

if the margin of a water body has moved as a result of accretion and erosion, then… (2)

Answer 6

• any erosion that affects the water boundary must be accounted for unless the boundary is accepted under rule 15 (acceptance of boundaries)
• subject to above, the boundary may be adopted in its previously defined position if entitlement to accretion isn’t being claimed

Question 7

10 Water boundaries

If the margin of a water body has moved by processes other than accretion and erosion, the existing water boundary may be… (2)

Answer 7

• adopted and set in its previously defined postion as an irregular boundary
• converted to one or more right line boundaries

Question 8

11 Water centre-line boundary

What is a water centre-line boundary, new boundary, existing boundary? (3)

Answer 8

• a water centre-line boundary follows the line midway between the landward margins of a stream or river bed
• an existing irregular boundary that followed the centre-line of a water body may be adopted in its previously defined position as a water centre-line boundary
• a new boundary must not be a water centre-line boundary

Question 9

12 Height-limited boundaries

A height-limited boundary must… (1)

The boundary must be either… (2)

Answer 9

• define the upper or lower extent of a parcel
• a surface that is mathematically described, if at least 1 point has a reduced level
• a surface/bed of a water body
