General Residential and Miscellaneous Development Plan Amendment

We recommend viewing this page in Google Chrome. 

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.

To explain what is changing and why, we have produced a short, descriptive video that can be viewed on YouTube.

What areas are affected by the DPA?

All properties within the Residential Zone and in particular the Medium Density Policy Area 40 are affected by the DPA.

Community Engagement

Statutory consultation on the drat DPA took place from 30 May to 26 July 2017. The draft DPA was granted interim authorisation by the Minister, giving the amendment immediate effect on 30 May 2017 to prevent inappropriate development and promote orderly planning.

Through the consultation period, our comprehensive engagement program included:

  • a direct email to over 158 community contacts and also people who requested to be on our database
  • a mail out to every home in the Residential Zone (approximately 66,000) with a flyer informing people of the DPA engagement
  • three advertisements in the Southern Times Messenger on 31 May, 7 June and 5 July 2017
  • one advertisement in The Advertiser on 30 May 2017
  • a Southern Times Messenger ‘Onka News’ article on 7 June 2017
  • four community information sessions at Noarlunga, Aberfoyle Park and two sessions at Seaford
  • displays at all Customer Service Centres, libraries and Community Centres
  • Facebook and Twitter feeds
  • a public meeting held on 1 August 2017. 

Response to submissions - how has my feedback affected the outcome?

We received 101 submissions including two petitions. All written submissions received during the consultation period, along with the verbal submissions heard at the public meeting, have been summarised and responded to in the Summary of Consultation and Proposed Amendment (SCPA) report.

General Residential DPA imageThe General Residential and Miscellaneous DPA policy has been amended taking into consideration the submissions made during the consultation period and those who spoke at the public meeting, along with the outcomes of the elected member workshop held on 5 September. The information in the SCPA report has formed the basis for the recommended changes to the General Residential and Miscellaneous DPA – ‘The Amendment’. The Minister for Planning will now need to agree to the changes in order for them to become consolidated into the Development Plan.

Next Steps

The Summary of Consultations and Proposed Amendments (SCPA) Report and the General Residential Development Plan Amendment (DPA) has been submitted to the Minister for Planning for consideration.

The Minister seeks to complete the DPA by December 2017. He may accept the Development Plan Amendment as submitted by Council, or may propose amendments to the document after further consultation with Council.

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).

Background information

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.

What are we changing?

The DPA reflects the outcomes of the community engagement and incorporates improved design parameters and encourages new housing in close proximity to high quality public transport infrastructure.

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).
