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 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.

What are we changing?

The proposed changes seek to encourage medium density development where it works best. This will result in reducing the overall size and amending the Medium Density Policy Area 40 boundaries so that our highest densities are located within:

  • 400m catchments of strategic (higher order centres being District and Regional) that are well serviced by frequent public transport
  • 800m catchments of train stations
  • 400m catchments of high amenity coastal open space serviced by local shops/cafes and frequent public transport.

This means that there will be some new Medium Density Policy Areas that meet the criteria as above in Aberfoyle Park, Morphett Vale, Christies Beach, Port Noarlunga, Noarlunga Downs and Aldinga.

The Medium Density Policy Area will be removed from some areas that are outside of centre and transport walking distance catchments.

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). These precincts have minimum site area, building height and siting criteria to reflect desired concentrations of higher density and encourage infill development in these locations

Minimum allotment sizes will be increased in the remainder of our Medium Density Policy Area 40 and also in the Residential Zone to provide for a stepped transition to 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 

The formal engagement period for the DPA ran for eight weeks and ended at 5pm on 26 July 2017.

To ensure our community was aware of the changes in the DPA, our comprehensive engagement program included:

  • a mail out to every home in the Residential Zone (approx. 66,000)
  • advertisements in the local Messenger on 31 May, 7 June, 5 July
  • article in Messenger 7 June (page 5)
  • advertisement in the Advertiser on 30 May 2017
  • website active from 30 May which has a link to an animated video and interactive map
  • displays at Customer Service Centres (Noarlunga, Aberfoyle Park, Woodcroft, Aldinga and Willunga)
  • displays at all Council Libraries and Community Centres
  • social media: Council’s Facebook and Twitter

We held 4 community information sessions across the council area during June 2017 (with approx. 175 people attending) at:

  • Seaford Community Centre (1 June)
  • Noarlunga Civic Centre (15 June)
  • Aberfoyle Community Centre (19 June Northern Community Forum)
  • Seaford Library (29 June)

You can download copies of all the written submissions we received during the consultation period below:

A public meeting was 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 were heard in relation to the DPA and the submissions.  

How will my feedback affect the outcome?

We will take into consideration written and verbal submissions in making any recommendation to alter the DPA policy. These submissions will be summarised and responded to in a ‘Summary of Consultations and Proposed Amendments Report’. The DPA policy may then be amended to address concerns. Council’s Strategic Directions 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

The Summary of Consultations and Proposed Amendments Report and the final Amendment will be considered at the 17 October 2017 Council meeting prior to submission to the Minister for Planning for approval.
