Lonsdale Residential amendment

Current status

The Lonsdale Residential Development Plan Amendment (DPA) (6.0 MB PDF) was approved by the Minister for Planning by notice in the South Australian Government Gazette on 2 July 2020.

Purpose of the amendment

The DPA proposed to rezone approximately 12 hectares of vacant land in Lonsdale, located between the SA Water desalination plant (Sigma Road) and residential development in Hallett Cove (Bolingbroke Road), to provide for low to medium density residential development.

With the closure of the oil refinery in 2009 and the subsequent development of the SA Water desalination plant reducing the impacts on the surrounding environment, the land is now able to be considered for residential purposes by rezoning through a Development Plan Amendment process.

In determining the future policy framework for this site, the DPA process considered a range of noise and air quality investigations into potential nearby sources. The Environment Protection Authority has provided advice during the DPA process.

The DPA also sought to rezone approximately six hectares of adjacent land owned by the City of Marion from Open Space to Coastal Conservation Zone to affiliate it with the broader Hallett Headland coastal reserve.

Area affected by the amendment

The community information sheet (1.9 MB PDF) includes a map of the area affected and also provides details about the proposed amendment and the amendment process.

The DPA affects land within the Marion Council Development Plan and Onkaparinga Council Development Plan .

Council boundary realignment

As the City of Marion and Onkaparinga boundaries bisect the subject land, the landowner has advised the SA Local Government Boundaries Commission of its intention to lodge an application (if and when the rezoning is approved) to realign the Council boundaries so that the entire site is within the City of Marion. This will enable a consistent approach to managing the development and into the future.

This process is separate to the rezoning process and is undertaken under the Local Government Act 1999 and the SA Local Government Boundaries Commission. It will require a separate public consultation process before completion. Nonetheless, the public is invited to consider the matter as part of this DPA process.

Have your say

Consultation on Ministerial DPAs is managed by the South Australian State Planning Commission, an independent statutory body which provides advice to the Minister on planning and development issues.

An information/drop-in session was held on 23 November 2019 at the Cove Civic Centre.

The period for receiving written submissions closed on 18 December 2019, followed by a public meeting held on 16 January 2020.
