Areas of lawn, garden and, if nominated, areas of indigenous/low water use plant species MUST be indicated on your development application plans.
If nominating indigenous/low water use plant species, a landscape plan listing individual plant species MUST be submitted with the development application.
For garden areas containing large existing trees, a maximum ground area of 4m² per tree, located directly underneath the tree, can be nominated as low water use. This applies to any tree species, provided the existing trunk size of the tree is greater than 30cm diameter, measured at 1 meter above ground level.

Allocating common landscape areas to central alternative water systems.
As the central water tanks or recycled water system may not be able to provide alternative water to all common landscape areas you will need to tell BASIX the area of common landscape that will be serviced by each central system.
All areas of lawn and garden included in your development must be on your development application plans.
BASIX requires you to enter your total area of lawn and/or garden as measured directly from the development application plans and this is the area in square metres nominated as lawn and/or garden beds, including any areas of indigenous/low water use plant species.
For Landscape Area Method 1, the total area is the entire pervious vegetated area. This includes:
For Landscape Area Method 2, the total area is limited to the formal garden and lawn area. This includes:
In the single dwelling tool if no garden area is nominated for your development BASIX will calculate outdoor water use based on an assumed garden area relative to the size of your site and the footprint of your proposed development.
Please refer to the apportionment guidelines here to determine the landscaping area associated with the proposed dwelling on a site with an existing dwelling.
Alternatively, if the proposed dwelling on a site with an existing dwelling contains only 1 bedroom, you may specify “0” or a small value as the area of garden and lawn. However, you will need to apply to have this adjustment made to your BASIX project through alternative assessment. Please contact the BASIX helpdesk for more details.
Low water use species means a species of vegetation identified as a 'one drop plant' under Sydney Water's Plant Selector Water Drop Rating Scheme (available at www.sydneywater.com.au), or a species of vegetation which the local council for that area deems is a low water use species in that area. These can include Indigenous species that are suited to the environment and climatic conditions of the area.
Indigenous species means a species of vegetation identified in a local council list as being indigenous to the land on which the proposed development is to be carried out (available by pdf download below), or a species of vegetation which the local council for that area deems is an indigenous species in that area.

If your LGA is not listed in the table above, you need to contact your local council for a list of low water demand and/or indigenous species which they will accept as part of a landscape plan to meet your BASIX water commitments.
You should also consider the suitability of species selected for your site in terms of soil type, exposure, shade, mature plant height, and on-going maintenance issues such as the potential impact on sewerage services. Further information is available from your local council and the Sydney Water plant selector.
