Non-Aboriginal heritage

Non-Aboriginal heritage includes places and objects of high cultural value that contribute to a sense of history and identity for the community. It includes places and objects that are of aesthetic, archaeological, architectural, cultural, scientific or social significance.

While not typical, it can also include places or objects that have Aboriginal cultural heritage values.

Approach

The assessment of the non-Aboriginal heritage impacts of the project included multiple investigations undertaken as the project design evolved.

The potential for the project to impact non-Aboriginal heritage has been assessed by confirming the presence of the following heritage places and objects, and their values within and immediately adjacent to the project alignment:

World Heritage
National Heritage
State Heritage
Local Heritage
Representative Buildings (formerly known as contributory items)
the Department’s Roadside Significant Sites
Historic and Character Areas Overlays defined by the Planning and Design Code.

Once the non-Aboriginal heritage places and their values were confirmed, the potential for impacts during both construction and operation of the current design was considered. As a result, additional investigations for several non-Aboriginal heritage places were undertaken due to their immediate proximity to the design. These were the:

Hindmarsh Cemetery and Sexton's Cottage
Former Thebarton Sub-Control Station (WWII bunker)
Brickworks Hoffman kiln.

Representative Buildings

Representative Buildings are examples of buildings that contribute to the character of an area. These were previously known as contributory Heritage places.

To determine the number of buildings, a revised area of interest – with a 50m buffer each side of the project area was applied. This revised area was applied because the potential extent for indirect vibration impact to Representative Buildings from a tunnel boring machine (TBM) operations alone are anticipated to be less. This extent also aligns with targets in the Department’s Environment and Heritage Technical Manual (EHTM), Attachment 7D, the Management of Noise and Vibration: Construction and Maintenance Activities Environmental Instruction 21.7 .

Seventy-one Representative Buildings were identified within the revised non-Aboriginal heritage area of interest. Most of these buildings are in the area near the Northern Tunnels, above the tunnel alignment where the TBMs will be operating and include:

Impacts and mitigation measures

Without suitable mitigation measures, construction of the project has the potential to cause direct and indirect impacts on the form, fabric, setting, character and heritage values of heritage places.

Direct impacts are those that may result from construction at the surface which directly affects a heritage place.

Indirect impacts are caused by project activities that don't directly interact with a non-Aboriginal heritage item or place but can still cause impact to these structures during construction or operation. Vibration, visual impacts, changes to place and settings are all potential examples of indirect impacts caused by construction or operation of the project. An evaluation of each potential non-Aboriginal heritage impact was undertaken for both the construction and operational phases of the project.

The potential impacts to non-Aboriginal heritage have been assessed by applying the Project’s assessment methodology to the non-Aboriginal heritage area of interest. The objective of this methodology is to document and assess the social and environmental (including Heritage) risks from the project and identify management and mitigation measures to reduce these risks.

Construction impacts

The assessment identified the potential non-Aboriginal Heritage impacts during construction to be:

Direct impacts

The project will: manage undiscovered non-Aboriginal Heritage places or objects discovered during construction in accordance with requirements of the Heritage Places Act 1993 document in the CEMP or as sub-plan any actions required to manage undiscovered heritage and associated risks.

Operational impacts

Operational impacts are anticipated to be limited for this project as the direct and indirect impacts to State, Local, Representative Buildings, RSS and Heritage and Character Area Overlay areas will occur when the infrastructure is constructed, not once it is operating.

However, the impact assessment did identify the following operational non-Aboriginal heritage impact:

the State Heritage Place Hindmarsh Cemetery and Sexton's Cottage. A visual impact is anticipated to remain as a result of operating and maintaining the new bridge over the River Torrens / Karrawirra Parri.

See how impacts will be minimised or avoided for information regarding minimising impacts.

Operational impacts	Key mitigation measures
Operation (and maintenance) resulting in an indirect impact to a State, Local, Representative Building or RSS	The project will have: engaged a suitably qualified Heritage architect/specialist to undertake a Heritage impact assessment(s) where required liaised with the relevant government agencies regarding the requirements for the heritage sites and, if necessary, obtain any approvals and implement recommendations/requirements minimised the potential impact to non-Aboriginal heritage places during design. This includes identifying opportunities to enhance the setting and context of heritage places within the project corridor as part of the project’s Urban Design Strategy.

How impacts will be minimised or avoided

During design the project has confirmed that application of the Department’s Master Specification (MS), with its links to relevant parts of the Environment and Heritage Technical Manual (EHTM) will be used to mitigate the construction and operational impacts to non-Aboriginal heritage.

Of relevance to non-Aboriginal heritage are:

The MS and EHTM require the project to develop and undertake assessments and prepare reports that document required outcomes during construction. These include:

Heritage Impact Assessments (HIA) for impacts to State Heritage Places
conservation/Heritage Management Plan for heritage places impacted by the project
property condition assessments
compliance with the Departments Road Traffic Noise Guidelines
Construction Vibration Assessment (CVA)
Contractor’s Environmental Management Plan (CEMP)
Construction Noise and Vibration Management Plan (CNVMP)
