General Residential and Miscellaneous Development Plan Amendment

The City of Onkaparinga is planning to improve its policies related to general residential and medium density development through the General Residential and Miscellaneous DPA.

This comprehensive refinement to policy seeks to improve outcomes throughout the residential area while still enabling diverse housing to support a growing and changing population.

In order to prevent inappropriate development and promote orderly planning, the draft DPA has been granted ‘interim authorisation’ by the Minister for Planning, giving the amendment immediate effect.

Improving our medium density policies

To explain what is changing and why, we have produced a short, descriptive video. View this video on YouTube.

What are we changing?

The proposed changes seek to encourage medium density development where it works best.

Some areas from the Medium Density Policy Area will be removed and the greatest varieties in housing types (and the highest densities) are encouraged in new ‘Targeted Infill Precincts’. These precincts are located at 200 metres from Regional and District Centres (and Woodcroft Neighbourhood Centre).

Minimum allotment sizes will be increased in the remainder of our Medium Density Policy Area 40 and also in the Residential Zone. This may reduce the number of new dwellings possible on a site.

These changes will be supported by design improvements including reduced heights to two storeys (other than in the Targeted Infill Precincts and in the Medium Density Policy Area along the coast and adjoining public open space), increased setbacks and increased on site car parking, improved opportunity for landscaping and bin storage (to name a few).

Why are we undertaking this DPA?

Our city currently provides approximately 2200 hectares of land designated for medium density residential infill. The Medium Density Policy Area 40 was introduced in 2010 to support higher density housing in proximity to centres, public transport and open space. 

Across the Residential Zone, particularly in the Medium Density Policy Area 40, dwellings are being developed in a variety of forms, densities, heights and styles – ranging from one to three storeys. However, we understand that not all new developments are welcomed by the community due to the design concerns including setbacks, loss of privacy, parking on the street, bin storage and lack of landscaping opportunities. We also want to encourage growth where it works best – nearby major activity centres and public transport. Through the General Residential and Miscellaneous DPA we are hoping to resolve many of these concerns.

Community Engagement – Have Your Say

Council has previously engaged with the community on this issue from 24 November until 23 January 2015. This consultation on the draft Statement of Intent (SOI) was not a statutory requirement but rather an opportunity for council to learn from the community at the early stages of the project to inform its scope.

The local community has a continued interest in this issue and will have an opportunity to have a say regarding the future policy for medium density residential development as part of the formal 8 weeks statutory consultation period. The community engagement period will extend from 30 May to 26 July 2017.

We will be holding community information drop-in sessions across the council area at the following venues:

  • Noarlunga Civic Centre 15 June 6-8pm
    Ramsay Place
    Noarlunga Centre

Southern residents will have another opportunity to have their say at:

  • Seaford Library
    29 June, 5-6.30pm
    Grand Boulevard, Seaford

We will also be attending the Northern Community Forum:

  • Aberfoyle Community Centre (Northern Community Forum)
    19 June 7.30-9.30pm
    1 Jessica Street, Aberfoyle Park

If you wish to make a submission, the guide to making submissions and submission form is available below. Written submissions regarding the DPA should be submitted no later than 5pm on Wednesday 26 July 2017. All submissions should be addressed to

All submissions should clearly indicate whether you wish to be heard in support of your submission at the public hearing.  If you wish to lodge your submission electronically, please email it to

Copies of all written submissions received will be available for inspection by interested persons at our Noarlunga Office, Ramsay Place, Noarlunga Centre from Thursday 27 July 2017 until the conclusion of the public hearing.

If required, a public hearing will be held at our Noarlunga Office, Ramsay Place, Noarlunga Centre in conjunction with the Council’s Strategic Directions Committee meeting at 7pm on 01 August 2017 at which time interested persons may be heard in relation to the DPA and the submissions.  There will be no public hearing if no submissions are received or if no submission makes a request to be heard.

How will my feedback affect the outcome?

Once the engagement period has finished, we will summarise all submissions and respond in a ‘Summary of Consultations and Proposed Amendments Report’. The policy may then be amended to address concerns. Council’s Committee will have an opportunity to review the Summary of Consultations and Proposed Amendments Report and final draft policy prior to us sending to the Minister.

What is the process for amending the Development Plan?

The process of amending a Development plan is outlined in the Development Act, 1993 and explained by the Department of Planning, Transport and Infrastructure through their Guide to Development Plans and Development Plan Amendments 

This DPA process has been informed by previous Council investigations and consultation with the community (as shown in the diagram below).

Next Steps

Following the close of community engagement, we will hold a public hearing on the DPA at Council’s Noarlunga office at 7pm on Tuesday 1 August 2017. Those who made a written submission will have an opportunity to speak in support of their submission.

A summary of all submissions will be presented to Council. We will take into consideration written and verbal submissions in making any recommendation to alter the DPA policy.
