- What is the misclose of the level run?
- Is this acceptable? Why or why not?
2. The site plan attached below shows a proposed cottage on a typical residential block of land. The proposed cottage is single storey and has a side setback requirement of 900mm (i.e. the wall to boundary dimension for the side boundaries).
The house is shown set 900mm from the Southern boundary.
- Determine if the northern side boundary complies with minimum 900mm setback.
- Calculate the dimensions of the side boundaries, ‘ad’ and ‘ce’.
Show all your working.
3. The second site plan attached below depicts a 20 x 40m block of land with a 5 x 5m grid shown in dotted lines. The grid is identified west to east with the numerals 1 to 5 and north to south A to I.
The table below gives the ‘spot’ levels taken on the grid points. The levels have been recorded to the nearest 10mm.

Plot the spot levels on the site plan grid and draw the contour lines at an interval of 0.500m intervals.
If you require clarification, please contact your teacher at OTEN to discuss.
