Areas of compiled residue lots after survey 

The accuracy requirements for compiled residue lots (after the survey) are outlined in clause 26(3) Surveying and Spatial Information Regulation 2017.

Areas for lots that close within the acceptable limits should be shown as 'By Calc'.

Areas for lots that don't close or cannot be closed within the acceptable limits must be derived by subtracting the area of the surveyed lot(s) from the area shown on the base plan, and should be shown on the new plan as 'By Ded'n'. 

Note  Plans that comply with these requirements do not require prior written approval of the Plan and Title Advisor.
