Note: the minimum canopy tree requirement may be met with either an existing canopy tree, by planting a new canopy tree, or a combination of both.
| Site area | Canopy tree requirement |
|---|---|
| 100 sqm or less | 1 tree |
| 101 sqm to 200 sqm | 2 trees |
| 201 sqm to 500 sqm | 3 trees |
| 501 sqm to 700 sqm | 4 trees |
| 701 sqm to 1000 sqm | 6 trees |
| Above 1001 sqm | A total canopy cover within the site that is equal to at least 20 per cent of the site area * |
* Note:
If the site has an area of more than 1000 square metres and the existing total canopy cover within the site is more than 20 per cent of the site area, the canopy trees on the site should achieve a total canopy cover within the site that is equal to at least 20 per cent of the site area plus 50 per cent of the area of existing canopy cover that exceeds 20 per cent.
Example:
If the site area is 2000 square metres and the existing total canopy cover within the site is 30 per cent of the site area, the required total canopy cover is 25 per cent (20% + [(0.5 x (30% -20%)] = 25%).
The minimum canopy tree requirement may be met with either an existing canopy tree, by planting a new canopy tree, or a combination of both.A new canopy tree should be planted in:
a minimum deep soil area of at least 12 square metres with a minimum dimension of at least 2.5 metres; or
in a planter with a minimum volume of 12 cubic metres with a minimum depth of at least 0.8 metres of planter soil; or
if the proposed canopy tree has an expected canopy diameter of more than 8 metres at maturity, deep soil area or a planter area that is to the satisfaction of the responsible authority.
