Integrated Development is an efficient way for Heritage Council of NSW and a local council to both assess proposals that will impact a State Heritage Register listed item.
Integrated Development and the Heritage Act 1977
If you lodge a Development Application (DA) with a local council for development to a State Heritage Register item, that application will become an Integrated Development Application (IDA). This is unless approval under the Heritage Act has already been obtained and provided as part of the DA, or an exemption applies.
Local councils cannot issue development consent under the Environmental Planning and Assessment Act 1979 (EP&A Act) unless the Heritage Council advises it will grant approval under the Heritage Act 1977 when an application is later made to it.
What are the benefits of an Integrated Development Application?
The IDA process enables local council and all approval bodies to assess a development application at the same time. This allows heritage issues to be identified and resolved before you lodge an application for approval under the Heritage Act, and means you know how that application will later be dealt with. If the Heritage Council tells the local council it will grant approval for the development under the Heritage Act, it must grant that approval when you apply. If the Heritage Council advises the local council it will not issue an approval under the Heritage Act, council must refuse the application.
The IDA process reduces the need to modify approvals to address concerns of council and other approval bodies. It can also save you time, as applications will only be publicly exhibited once under the EP&A Act.
You can choose to obtain your Heritage Act approval first, however the IDA process is generally the recommended pathway.
What is the IDA process?
The main steps in this process are:
1. The IDA is lodged with the local council.
The council must refer the IDA to the Heritage Council within 14 days via the NSW Planning Portal. The Heritage Council can request additional information about the development.
2. The IDA is placed on public exhibition.
IDAs involving the Heritage Act must be exhibited by local council for at least 28 days.
3. The Heritage Council considers the IDA.
Following public exhibition, copies of any submissions received are sent to the Heritage Council. The Heritage Council then has 21 days to finish its assessment of the IDA and advise council if it will grant approval under the Heritage Act.
4. The IDA is determined under the EP&A Act.
If the local council grants consent for the IDA under the EP&A Act, you must then apply for approval with Heritage NSW, attaching council’s notice of determination and a copy of the approved plans along with the other essential supporting documents.
What supporting documents are required?
If the local council grants consent for the IDA under the EP&A Act, you must then apply for approval with Heritage NSW.
To enable an assessment of an IDA we require:
- Statement of Environmental Effects
- Statement of Heritage Impact
- Drawings and drawing table
- Council’s notice of determination
- a copy of the approved plans
and when there are known or suspected relics to manage on site:
- Historical Archaeological Assessment
- Archaeological Research Design
Refer to "Essential supporting documents" tab on the Concurrence and referral page for how to prepare, label and submit these documents.
Can an IDA approval be modified?
If you wish to modify a development consent granted under the EP&A Act or an approval granted under the Heritage Act, you should first lodge a s4.55 modification application under the EP&A Act with the local council.
Once determined, attach the consent to a s65A modification application under the Heritage Act and submit it to Heritage NSW.
For general information on the IDA process, contact your local council.
