What is deep planting?
Deep planting is planting that is 100% open to the sky (no overhead structures) and 100% in natural ground with no underground infrastructure (no underground car parks or service conduits encased in concrete).
What is not deep planting?
- Deep planting must be within the site boundaries so anything in council verge cannot be included.
- Podium planting
- Bio-retention basins
- Anything under a shade structure
The grey areas:
- Any deep planting that has a minimum dimension smaller than 3 or 4m (dependent on applicable code) and a minimum area of 25m2
- Paved areas
- Private open space
The term deep planting is specific to Brisbane City Council and specific outcomes about deep planting can be found in the following codes within the Brisbane City Plan 2014:
- Multiple dwelling code
- Centre or mixed-use code
- Childcare centre code
Although not yet implemented, it is important to be aware of the future changes to the Multiple Dwelling Code for residential projects in Brisbane City Council, namely townhouse and apartment developments.
The most significant changes proposed to deep planting include:
- Specifying 4m as the minimum dimension in the multiple dwelling code
- Changes to the way open space and deep planting interrelate, most notably that private and communal open space will no longer be allowed to be included in the area that makes up deep planting
Implications of these changes:
If adopted by Council, these changes may substantially reduce the net usable space of a site, which may, in some cases, create feasibility issues for our clients.
