PO1

Reconfiguration of lots does not compromise or adversely impact upon the efficiency and integrity of major electricity and bulk water supply infrastructure networks.

PO2

Lot reconfiguration integrates major infrastructure sites and corridors within the overall layout. In particular, the neighbourhood design:

1. ensures land of sufficient size and suitability is allocated to accommodate the existing and future major infrastructure network
2. as far as possible, minimises the likely visual prominence of major infrastructure, and
3. provides for an interface or relationship with surrounding uses that minimises the potential for nuisance (including noise and odour), health and safety concerns.

No acceptable outcome is nominated.

Note—Applicants should consult with the electricity providers early in the master planning process to determine electricity infrastructure requirements.

PO3

Landscaping is provided which substantively assists in screening and softening poles, towers or other structures and equipment associated with major infrastructure.

AO3

A minimum 5m wide densely planted landscaped buffer is provided, including provision for advanced trees and shrubs that will grow to a minimum height of 10m.

Note—Applicants may find further guidance in Powerlink's "Screening your home from powerlines – A guide for planting trees and shrubs outside of easements to screen powerlines".

PO4

Development within a water supply pipeline and buffer identified on the Regional infrastructure overlay map:

1. is located, designed and constructed to protect the integrity of the water supply pipeline, and
2. maintains adequate access for any required maintenance or upgrading work to the water supply pipeline.

AO4

Buildings and structures (other than those associated with electricity infrastructure) are setback a minimum of 10m from a water supply pipeline as identified on the Regional infrastructure overlay map.

PO5

Where the reconfiguration involves a major electricity infrastructure corridor, the corridor is incorporated within a useable public open space network wherever possible.

PO6

Where major electricity infrastructure is located within public open space, the dimensions and characteristics of the open space area are sufficient to accommodate the electricity easement or site, in combination with compatible recreational facilities and landscaping, so that:

1. it has an open and expansive character, with landscape design which assists in breaking up the linear and vertical dominance of the infrastructure
2. landscaping is located outside the easement area and substantively screens and softens the appearance of poles, towers or other structures, and
3. recreational facilities and landscaping are compatible with the electricity infrastructure, having regard to safety, height, the conductivity of materials and access to the electricity infrastructure by the electricity provider.

No acceptable outcome is nominated.

Note—The figures below provide an example of a well–integrated transmission corridor.

PO7

Where major electricity infrastructure is located in a road:

1. an attractive, functional and safe streetscape is achieved
2. street furniture, planting and lighting are compatible with the electricity infrastructure, having regard to safety, height, the conductivity of materials
3. the reserve has sufficient width to accommodate significant landscaping which assists in screening and softening poles, towers or other structures and equipment from nearby sensitive land uses
4. the clearances required under schedules 4 and 5 of the Electrical Safety Regulations 2002 can be achieved, and
5. convenient access to the infrastructure by the electricity provider is maintained.

PO8

Development does not increase risk to community health or safety, or the operation and reliability of major electricity or bulk water supply infrastructure.

PO9

Development involving a sensitive land use is sufficiently separated from major electricity or bulk water supply and wastewater infrastructure to minimise the likelihood of nuisance or complaint.

For electricity infrastructure.

AO9.1

Buildings (other than class 10 buildings) maintain a setback of at least:

1. 50m from a transmission (Powerlink operated) substation
2. 20m from any other substation, and
3. 20m from a transmission line easement.

For water or wastewater treatment plants

AO9.2

Sensitive land uses are not established or intensified within the buffer of a water or wastewater treatment plants identified on the Regional Infrastructure Overlay Map.

PO10

Development avoids potential noise nuisance from substations.

AO10

Noise emissions do not exceed 5db(A) above background noise level at the facia of a building measured in accordance with AS 1055.

PO11

Other than where they are separated from the infrastructure by a road, buildings are oriented to avoid direct overlooking of major electricity infrastructure or substations.

No acceptable outcome is nominated.

Note—The figure below provides an illustration of buildings oriented away from infrastructure.

PO12

Development includes sufficient space within the site to establish landscaping which substantively assists in screening and softening poles, towers or other structures and equipment associated with major electricity infrastructure and substations.

AO12

A minimum 3m wide densely planted landscaped buffer is provided along the boundary adjoining the major electricity infrastructure, including provision for advanced trees and shrubs that will grow to a minimum height of 10m.

Note—The figures below provide an example but are not drawn to scale. Applicants may find guidance in Powerlink's "Screening your home from powerlines – A guide for planting trees and shrubs outside of easements to screen powerlines". Applicants should also note that vegetation will need to maintain statutory clearances (refer Ergon's Standard for Vegetation Management and Standard for Vegetation Clearance Profile.) Applicants should also note that vegetation will need to maintain statutory clearances (refer Ergon's Standard for Vegetation Management and Standard for Vegetation Clearance Profile)

PO13

Major electricity or bulk water supply infrastructure within private land is protected by easement in favour of the service provider.

AO13

Existing easements are maintained and where none currently exist, new easements are created which are sufficient for the provider's requirements.

PO14

Development does not compromise or adversely impact upon the efficiency and integrity of major electricity and bulk water supply infrastructure networks.

AO14

For bulk water infrastructure, buildings and structures (other than those associated with electricity infrastructure) are setback a minimum of 20m from a water supply pipeline.

No acceptable outcome for major electricity infrastructure.

PO15

Development within a water supply infrastructure buffer is located, designed and constructed to:

1. protect the integrity of the water supply infrastructure
2. maintains adequate access for any required maintenance or upgrading work to the water supply infrastructure.
