Development on contaminated land

If you intend to develop land that is contaminated, or has a history of contamination (e.g. former banana growing land), you may be required to take steps to investigate, remediate and validate the land contamination as part of your development proposal. This is to ensure the land is suitable for the proposed land use. 

Develop on contaminated land

Step 1.Check whether your land is contaminated

We have mapped land contamination in our local government area. You can view this in Council’s Online Mapping Tool by selecting the 'Planning & Environment' module and the 'Banana Cultivation 1943-94' layer.

Step 2.Seek advice

While Council can provide some general information, we recommend you seek specialist guidance and advice on all aspects of land contamination from a Certified Contaminated Land Consultant.

Step 3.Assessment may be requested

When a Development Application (DA) is submitted for a property which is mapped as potentially contaminated, or is known to have had historic use for banana cultivation, Council will generally request an assessment to be undertaken by a suitably accredited contaminated land consultant to determine if the land is contaminated.

Step 4.If the land is not contaminated

If the consultant deems that the site is not contaminated, Council’s records and Mapping system will be updated to reflect these findings. 

Step 5.If the land is contaminated

If contamination is found on the property, the Contamination Land Consultant will need to develop a Remedial Action Plan (RAP).

The Remedial Action Plan outlines the steps required to remediate the land to ensure it is suitable for its intended use.

Where remedial action has been carried out, the site must be validated to ensure that the objectives stated in the RAP have been achieved.  

Step 6.What if my land is not mapped as potentially contaminated but I know that a potentially contaminating land-use occurred on my land?

You will need to speak with a certified contaminated land consultant who can provide specialist guidance and advice on the potentially contaminating land-use.

It is also important to notify Council so that the contaminated land records for the site can be updated.
