1. INTRODUCTION

This Environmental Management Plan (EMP) outlines the mitigation measures to be implemented to

manage any environmental impacts resulting from Amendment No. 2 of the Shire of Augusta-

Margaret River Local Planning Scheme No. 1 and the subsequent development of this land, which is

being proposed by LandCorp.

1.1 LOCATION

The Scheme Amendment relates to an area of land to the south-east of the existing Gracetown

townsite, located approximately 12 kilometres (km) north-west of Margaret River in the south-west of

Western Australia, 270 km south of Perth (Figure 1). The scheme amendment area is located within

Lot 300 Salter St, Gracetown, and is currently Unallocated Crown Land (UCL) (Figure 2). The

subject land covers an area of 14.67 ha.

1.2 BACKGROUND

The existing Gracetown townsite consists of 150 residential units, of which approximately 50 are

occupied by permanent residents. As part of a Cabinet decision, in principle agreement was granted to

plan and develop limited additional residential within the townsite of Gracetown.

LandCorp proposes to develop the scheme amendment area in order to meet market demand for

residential home sites in the area. LandCorp is proposing to expand the existing Gracetown townsite

for a residential development consisting of approximately 136 lots. Amendment of the Shire of

Augusta-Margaret River Local Planning Scheme No. 1 was required to allow development of the

proposed residential area; rezoning the subject land from ‘Parks and Recreation’ to ‘Future

Development’.

In October 2007, this proposed amendment was referred to the Environmental Protection Authority

(EPA) under Section 81 of the Planning and Development Act 2005. The EPA advised of its decision

to assess the scheme, outlining that an Environmental Review (ER) was required to be prepared, in

accordance with the Instructions issued concerning the scope and content of the ER. The proposed

amendment was not assessed by the EPA and the referral became null and void. In May 2011, this

proposed amendment was referred again to the EPA under Section 81 of the Planning and

Development Act 2005. In a notice dated 17 October 2011 the EPA advised of its decision to not

assess the scheme and provided advice and recommendations which have been taken into account by

this EMP.

1.3 PURPOSE AND SCOPE OF EMP

The overall purpose of this EMP is to describe measures to protect significant environmental features

in the scheme amendment area and surrounds. This EMP documents LandCorp’s environmental

management objectives and strategies in relation to the proposed development of the scheme

amendment area, including:

• measures to prevent, reduce and mitigate any potential environmental impacts from the Scheme

Amendment and subsequent development concept

• details of the timing and persons responsible for implementation of these measures

• monitoring and reporting procedures.

The EMP addresses the following factors through a suite of management plans that are detailed in

subsequent sections:

• biodiversity management

• drainage and nutrient management

• Aboriginal heritage management

• waste management

• soil contamination management

• dust management

• noise management.

Fire management is addressed separately in the Fire Management Plan (Appendix 1) prepared by

FirePlan WA (2010) (see Section 1.5).

1.4 STRUCTURE OF EMP

The management plans in this EMP have been prepared in accordance with EPA Position Statement

No. 8 – Environmental Protection in Natural Resource Management (EPA 2005) and relevant

Department of Environment and Conservation (DEC) guidelines. Each management plan:

• defines management objectives for the environmental factor it addresses

• describes management measures required to achieve the environmental objectives related to the

environmental factor

• provides a description of monitoring and performance criteria, as required, for meeting the

objectives related to the environmental factor

• describes contingency measures to be implemented in the event of unexpected or unacceptable

environmental outcomes

• outlines responsibilities and timing of implementation for described measures.


LAN10072_EMP_VA2 - 10/12/2012 5

The EMP also details the overall environmental management framework, including:

• communications and training

• environmental incident reporting

• public complaint resolution

• stakeholder consultation

• auditing

• review and revision.

1.5 FIRE MANAGEMENT PLAN

This EMP should be read in conjunction with the Fire Management Plan prepared by FirePlan WA

(2010) (Appendix 1).

The Fire Management Plan addresses fire management associated with the residential development

area and details:

• a bush fire hazard assessment

• fire management including:

• road system

• firebreaks and low fuel buffers

• dwelling construction

• building protection zones

• hazard separation zone

• external public open space

• multiple use corridors

• community education

• visitor safety in the event of a bushfire

• fire fighting facilities

• responsibilities of the property owners, developers and Shire of Augusta-Margaret River.

2. DESCRIPTION OF SCHEME AMENDMENT AND ASSOCIATED

DEVELOPMENT CONCEPT

2.1 ENVIRONMENTAL SETTING

The existing physical, biological and social environment of Gracetown and surrounds is detailed in

Chapter 1, Section 2 of the Environmental Review (ER) for the Scheme Amendment.

2.2 OVERVIEW OF DEVELOPMENT CONCEPT

The key components of the Scheme Amendment and associated development concept are:

1. The area of the townsite will be increased by 14.67 ha, to the south-east of the existing townsite,

to include approximately 136 lots which will accommodate 146 housing units.

2. The number of permanent residents in the town will increase by approximately 100 people, based

on the current concept plan for the area to be rezoned.

3. Solar voltaic panels on house roofs will generate electricity and any excess will be exported to the

grid for use elsewhere.

4. A reticulated sewerage treatment system will be established in both the new and existing town

site areas and will replace existing septic tanks.

5. All water required by Gracetown will continue to be supplied from within the town (i.e.

Gracetown will not be connected to Water Corporation Scheme water).

There will be a 21.1 ha fire management area surrounding the scheme amendment area and residential

development for bushfire management, of which approximately 13.42 ha will be within Lot 300.

A wastewater treatment plant is proposed to service the existing and new residences however, as it is

not relevant to this Scheme Amendment assessment, it is not addressed in this document.

Figure 3 provides a conceptual layout of residences within the scheme amendment area.

3. BIODIVERSITY MANAGEMENT PLAN

3.1 DESCRIPTION

3.1.1 Vegetation and flora

The majority of the scheme amendment area is covered by undisturbed native vegetation of the

Gracetown vegetation complex, 71% of this vegetation complex occurs in formal reserves. Two site

vegetation communities (and one ‘degraded’ category) were mapped in the proposed scheme

amendment area by Mattiske (2006a). None of these communities are listed as Threatened Ecological

Communities (TECs) by the DEC or listed under the Commonwealth Environment Protection and

Biodiversity Conservation Act 1999 (EPBC Act).

The condition of the vegetation in the scheme amendment area varies from a mosaic of ‘pristine’ and

‘excellent’, to ‘completely degraded’ in areas where access tracks have been created. The potential for

the occurrence of Dieback (Phytophthora cinnamomi) within the scheme amendment area is

considered relatively low (Mattiske 2008). Of the 35 introduced/weed taxa recorded on-site, only one

(Zantedeschia aethiopica – Arum Lily) is listed as a Declared Plant by the Department of Agriculture

and Food Western Australia (2007).

No Declared Rare Flora species, pursuant to the Wildlife Conservation Act 1950 (Wildlife Act) and

listed by the Western Australian Herbarium (2006), were recorded by Mattiske (2006a; 2006b) during

the two surveys of the scheme amendment area. No Threatened Flora species, pursuant to Section 179

of the Commonwealth EPBC Act, were recorded within the scheme amendment area. One Priority 2

species, Caladenia abbreviata, and one Priority 4 species, Banksia sessilis var. cordata, were recorded

within the scheme amendment area (Mattiske 2006a; Rooks 2008).

A more detailed description of vegetation and flora is contained in Chapter 3, Section 1 of the ER.

3.1.2 Fauna habitat

As mentioned in the Section 3.1.1 above, two vegetation communities occur in the scheme amendment

area and these habitats are common in the local area, including the nearby Leeuwin-Naturaliste

National Park.

The scheme amendment area contains feeding habitat for Carnaby’s and Baudin’s Black-Cockatoo and

is also known to support Quenda and the South-west Carpet Python. A Western Ringtail Possum

(WRP) was recorded on the adjacent Unallocated Crown Land and four dreys (self-built bird-like

nests) were located within the scheme amendment area, however no WRPs were observed during the

surveys.

3.1.3 Fauna

Terrestrial fauna

A total of 154 vertebrate fauna species including birds, mammals, reptile and amphibians could

potentially occur in the scheme amendment area. A variety of invertebrates could also occur in the

area (Western Wildlife 2007).

Conservation significant vertebrate species recorded within the proposed scheme amendment area are:


LAN10072_EMP_VA2 - 10/12/2012 9

• Calyptorhynchus baudinii (Baudin’s Black-Cockatoo)

• Calyptorhynchus latirostris (Carnaby’s Black-Cockatoo)

• Isoodon obesulus (Quenda)

• Merops ornatus (Rainbow Bee-eater)

• Morelia spilota imbricata (South-west Carpet Python)

• Pseudocheirus occidentalis (Western Ringtail Possum).

Four invertebrate species of conservation significance were identified on DEC’s Threatened and

Priority Fauna database for the area; however, they are unlikely to occur within the scheme

amendment area due to a lack of suitable habitat.

A more detailed description of the terrestrial fauna of the scheme amendment area is included in

Chapter 3, Section 2 of the ER.

Subterranean fauna

Subterranean fauna, both stygal and troglobitic, have been recorded from several locations in the

vicinity of Gracetown, though no sampling has been completed in Gracetown itself (Biota 2008).

Many of the records in the vicinity are associated with cave systems, although some are associated

with surface water drainage and karstic limestone areas that do not appear to contain significant caves

(Biota 2008).

A more detailed description of the subterranean fauna of the scheme amendment area is included in

Chapter 3, Sections 2 and 3 of the ER.

3.2 ENVIRONMENTAL ASPECTS TO BE MANAGED

The following aspects of the scheme amendment area development have the potential to affect

biodiversity values:

• clearing will remove vegetation and possible significant flora species, and may result in the loss

of terrestrial fauna or lead to the fragmentation or loss of connectivity of habitat

• earthworks and installation of infrastructure leading to alteration of infiltration and runoff

regimes may change the depth of the watertable affecting groundwater-dependent vegetation

and potentially the subterranean microclimate (temperature and humidity in caves and air

spaces). Altering the runoff regime may also affect vegetation through increased erosion or

flooding. Earthworks may also disturb karst and cave formations that may provide habitat for

subterranean fauna

• human presence in the scheme amendment area will increase the risk of further land

disturbance resulting in degradation to vegetation and habitat, and will increase risks associated

with weeds and bush fires. Human presence may also deter fauna from residing in the vicinity

of disturbance areas due to noise emissions and general human activity. Habitation will

increase the risk of introducing feral species (including domestic pets) which may compete for

habitat and food, and may also prey on native species

• vehicle movements during the construction period and associated with the long-term

establishment of development may increase fauna fatalities.

Dust may be generated during clearing and earthworks, and may also result from strong winds over

exposed soil surfaces. Management of dust emissions is outlined in the Dust Management Plan of this

EMP (see Section 9).


LAN10072_EMP_VA2 - 10/12/2012 10

The risk of bushfires and fire management practices are outlined in the Fire Management Plan

prepared by FirePlan (2010). This document has been summarised in Section 1.5 and is contained in

Appendix 1.

3.3 ENVIRONMENTAL OBJECTIVES, TARGETS AND INDICATORS

The environmental objectives, targets and key performance indicators (KPIs) for biodiversity are

detailed in Table 1 below.

Table 1 Environmental objectives, targets and indicators for biodiversity management

LAN10072_EMP_VA2 - 10/12/2012 18

4. DRAINAGE AND NUTRIENT MANAGEMENT PLAN

4.1 DESCRIPTION

The scheme amendment area is located over freely draining Spearwood sands, underlain by a base of

Tamala Limestone, allowing rapid subsurface drainage. Rapid drainage, combined with the high

quartz content and low clay content of the soils means that opportunities for nutrient adsorption and

attenuation are limited. Drainage speed may be further enhanced by the presence of karst features in

limestone, such as sinkholes and channels, which allow rapid flow to occur.

The scheme amendment area forms part of a catchment that drains (though not through a defined

course) to the coastline north of the Gracetown townsite. Cowaramup Brook is the largest surface

water feature in the area and is located approximately 400 m north-east of the proposed development

site and is unlikely to receive surface runoff from the scheme amendment area. No other significant

surface water features have been identified within the area.

There is likely to be a high infiltration and throughflow rate in the proposed scheme amendment area

due to the geomorphology and the high porosity of the soils and geology. Infiltrated rainfall is

expected to flow westerly towards the coastline from the upslope areas to the east of Gracetown.

Groundwater is expected to be at least approximately 30 m below ground level within the scheme

amendment area.

A more detailed description of the geology and karst in the scheme amendment area is contained in

Chapter 3, Section 3 of the ER. A more detailed description of the surface and groundwater of the

scheme amendment area is included in Chapter 3, Section 4 of the ER.


The following environmental aspects of the scheme amendment area development may have the

potential to affect surface water and off-site groundwater quality and/or quantity:

• removal of native vegetation could lead to increased runoff and erosion

• installation of infrastructure and sealed surfaces such as roads and housing, could lead to

ponding, localised erosion, the interception, diversion and redirection of surface water pathways

and infiltration

• application of fertilisers and other nutrient sources in gardens may lead to increased nutrients

in surface water runoff and infiltrated rainfall

• spillage of hydrocarbons and unauthorised rubbish dumping may contaminate soils and

surface water.

Groundwater abstraction or discharge is not proposed as part of the development at the proposed

scheme amendment area, and as such, the proposed Scheme Amendment and subsequent development

will have no direct impact on the local groundwater aquifer. LandCorp is investigating the potential to

inject recycled wastewater from the development into the groundwater system. Groundwater injection

is not an aspect of the proposed Scheme Amendment, and will be addressed during subsequent

approval stages.


The environmental objectives, targets and KPIs for drainage and nutrient management are detailed in

Table 5 below.

4.4.3 Compliance with policy

EPA’s Instructions (issued in relation to the ER required to be prepared for Amendment No. 175),

outlined that the following policies and guidelines were required to be considered:

• Draft Guidance Statement No. 33: Environmental Guidance for Planning and Development,

Chapter C3 (this has since been finalised and released in May 2008) (EPA 2008)

• Statement of Planning Policy No. 6.1 – Leeuwin-Naturaliste Ridge Policy (WAPC 1998)

• Statement of Planning Policy No. 2 – Environment and Natural Resources Policy (WAPC 2003)

• Statement of Planning Policy No. 2.9 – Water Resources (WAPC 2006)

• Department of Water’s Stormwater Management Manual for Western Australia, including the

Decision Process for Stormwater Management in WA, with a specific mention of water-sensitive

urban design (DoW 2004).

The following sections demonstrate that, in relation to surface and groundwater quality and quantity,

the Scheme Amendment and associated development concept are in accordance with these documents.

Guidance Statement No. 33 – Water management

The Water Management section of this Guidance Statement specifically addresses stormwater

management, point source pollution and on-site effluent management. In terms of on-site effluent

management, a wastewater treatment plant is proposed to service the existing and new residences;

however, this is not addressed in this document as it is not relevant to this Scheme Amendment

assessment.


LAN10072_EMP_VA2 - 10/12/2012 21

A number of checklists, outlined in the Water Management section of this Guidance Statement, were

considered during the planning phases of the proposed residential development concept including

water issues during broadscale planning, point source pollution and inclusion of specific stormwater

management measures.

Geotechnical and hydrogeological assessments have been completed in relation to the proposed

scheme amendment area to provide information on the existing environment, with additional detailed

surveys providing further information. Various potential impacts and threats to surface and

groundwater quality and quantity have been identified. Management measures to address potential

impacts are outlined in this Drainage and Nutrient Management Plan, which includes specific

management objectives, targets and key performance indicators, and monitoring to ensure the

objectives are achieved. This Plan places particular emphasis on water-sensitive urban design and

reducing the risk of contamination, addressing all phases of development and providing for long-term

water management in the scheme amendment area.

Further details of the incorporation of stormwater management measures are provided in the

‘Stormwater Management Manual of Western Australia’ section below.

SPP No. 6.1 – Leeuwin-Naturaliste Ridge Policy

The proposed Scheme Amendment and associated development concept are in accordance with the

relevant surface and groundwater quality and quantity policies of the Leeuwin-Naturaliste Ridge

Policy (Table 7).

SPP No. 2 – Environment and Natural Resources Policy

State Planning Policy No. 2 – Environment and Natural Resources Policy outlines the position of the

Western Australian Planning Commission (WAPC) in relation to any proposed development which

has the potential to impact various environmental and natural resources. Section 5.2 of the policy

addresses Water Resources, and specifies six key considerations to be encompassed in planning

policies and decision making processes (Table 8).

Land use topics and policies Design strategies and mitigation measures (as outlined in Table 6), which demonstrate the scheme amendment and development concept are in accordance with the policy

Settlement

PS 1.6 Modified grid patterns for road layouts in subdivisions will respond to landform and vegetation features.


PS 1.10 Innovative, clustered subdivision design will be promoted with the aim of retaining a greater proportion of land for agricultural use and for the conservation of remnant vegetation.

Nestled battleaxe lots reduce clearing of native vegetation.

Maintain a minimum of 40% of the scheme amendment area for public open space (approximately 5.8 ha).


PS 1.11 Proposed urban development will be assessed against a range of design criteria, including water-sensitive design and other environmental features.

All residents are to install a rainwater tank for water supply purposes.

Septic tanks are not to be installed in the scheme amendment area.

Bores are not to be installed in the scheme amendment area.

All stormwater generated from the scheme amendment area shall be directed to on-site swales for infiltration, as far as practicable.

Permeable materials shall be used for all sealed surfaces (except roads), within the scheme amendment area.

PS 1.17 Development which necessitates servicing and infrastructure requirements may be supported provided:

• there is effective effluent disposal

• effective nutrient management.

There are no significant surface water features within the scheme amendment area.

The scheme amendment area forms part of a catchment that drains to the coastline.

A wastewater treatment plant is proposed to service the existing and new residences; however, this is not addressed in this document as it is not relevant to this Scheme Amendment assessment.

The Construction Contractor shall not store more than 500 L of hydrocarbons within the scheme amendment area.


No highly soluble phosphate fertilisers (i.e. phosphate fertilisers with a water solubility of more than 40%) shall be applied to rehabilitated/landscaped areas.

Nature conservation

PS 2.8 Proponents of development must ensure that it does not adversely affect the quality or quantity of surface and groundwater resources where required for the conservation of natural environmental values.

Refer to management objectives outlined in Table 5 and mitigation measures outlined in Table 6.

Resources

PS 7.6 The principles of ‘Integrated Catchment Management’, particularly nutrient management, will be applied to development and land use applications where appropriate.






LAN10072_EMP_VA2 - 10/12/2012 23

Table 8 Compliance of the Drainage and Nutrient Management Plan with water resource

considerations outlined in WAPC State Planning Policy No. 2

Considerations regarding water resources Design strategies and mitigation measures (as outlined in Table 6), which demonstrate the scheme amendment and development concept are in accordance with the policy

Consider mechanisms to protect, manage, conserve and enhance:

• wetlands of importance, Ramsar wetlands and wetlands identified in any relevant Environmental Protection Policy

• waterways

• estuaries

• marine environments

• gazetted public drinking water source areas

• other water sources which sustain catchments and identified environmental values.


The scheme amendment area forms part of a catchment that drains to the coastline.




Refer to Table 6, which outlines numerous mitigation measures to be implemented to manage potential effects on surface and groundwater quality and quantity.

Take account of the availability of water resources to ensure maintenance of water quality and quantity for existing and future environmental and human uses.

All residents shall install a rainwater tank for water supply purposes.



A wastewater treatment plant is proposed to service the existing and new residences; however, this is not addressed in this document as it is not relevant to this Scheme Amendment assessment. The treated wastewater is proposed to be utilised via a ‘third pipe’ system.

Encourage urban water management through water-sensitive design approaches that better manage stormwater quality and quantity; that reduce the impact of stormwater flows to streams, wetlands and coastal waters; and that control or remove pollutants and nutrients so as to improve water quality, retain habitats, conserve water and provide for recreational opportunities and conservation functions through multiple use drainage systems.



Rehabilitate and/or landscape disturbed areas that are not to be utilised post-construction, to stabilise soils and reduce erosion.


Ensure the provision of adequate setbacks between development and the foreshores of wetlands, waterways, estuaries and the coast, in order to maintain or improve the ecological or physical function of water bodies.


The scheme amendment area is located over 400 m from the coast shoreline and is behind the existing Gracetown townsite.

Consider flood risk by identifying floodways and land affected by 1 in 100 year flood events and avoid intensifying the potential for flooding as a result of inappropriately located land uses and development.



Consider the risks associated with nuisance or disease vector insects, in particular mosquitoes and midges, and ensure appropriate measures are applied to manage potential conflicts with community amenity and health, and environmental values.



There is likely to be a high infiltration and throughflow rate in the proposed scheme amendment area, therefore residence times for water would be low.


LAN10072_EMP_VA2 - 10/12/2012 24

Stormwater Management Manual for Western Australia

The overarching objective of the Stormwater Management Manual is sustainable development, by

promoting a balance between economic, social and environmental outcomes through policy, planning

and development. A variety of stormwater management options are presented for use in various built

environments. The Western Australian Stormwater Management Principles are listed in Table 10,

with examples of how these principles have been incorporated in the planning and design of the

scheme amendment area.

Table 10 Compliance of the Drainage and Nutrient Management Plan with the management

principles outlined in the Western Australian Stormwater Management Manual

Stormwater management principle Response regarding incorporation of these principles in the planning and design of the scheme amendment area

Incorporate water resource issues as early as possible in the land use planning process.

Water resource issues were incorporated in the initial scoping documents and concept plans.

Address water resources issues at the catchment and sub-catchment level.

This has been addressed by a number of mitigation measures including:

• all stormwater generated from the scheme amendment area shall be directed to on-site swales for infiltration, as far as practicable

• bores are not to be installed in the scheme amendment area

• septic tanks are not to be installed in the scheme amendment area

• a wastewater treatment plant is proposed to service the existing and new residences, with the treated wastewater to be utilised via a ‘third pipe’ system in residences.

Ensure stormwater management is part of total water cycle and natural resource management.



Define stormwater quality management objectives in relation to the sustainability of the receiving environment.

Refer to Table 5, which includes the following objective:

To prevent adverse changes to surface and groundwater quality resulting from development of the scheme amendment area.

The ultimate receiving environment for stormwater generated from the scheme amendment area is groundwater and eventually, the ocean. A number of mitigation measures have been implemented to minimise any potential impacts on water quality, including installing a wastewater treatment plant to service the existing and new residences.


LAN10072_EMP_VA2 - 10/12/2012 26

Stormwater management principle Response regarding incorporation of these principles in the planning and design of the scheme amendment area

5. LEEUWIN-NATURALISTE NATIONAL PARK MANAGEMENT PLAN

5.1 DESCRIPTION

The Leeuwin-Naturaliste National Park was established in 1957. The National Park generally hugs

the coastline from Bunker Bay in the north to Augusta in the south, though some areas extend further

inland. The Leeuwin-Naturaliste National Park is classified as Category II under the IUCN’s World

Commission on Protected Areas.


The following aspects of the scheme amendment area development and associated fire management

area have the potential to affect the Leeuwin-Naturaliste National Park:

• clearing will remove vegetation and may result in the loss of terrestrial fauna or lead to the

fragmentation or loss of connectivity of habitat

• human presence in the scheme amendment area will increase the risk of further land

disturbance resulting in degradation to vegetation and habitat, and will potentially increase risk

levels associated with weeds and bush fires. Human presence may also deter fauna from

residing in the vicinity of disturbance areas due to noise emissions and general human activity.

Habitation will increase the risk of introducing feral species (including domestic pets) which

may compete for habitat and food, and may also prey on native species. Increased human

presence may also improve surveillance of the surrounding area and deter unfavourable

activities

• vehicle movements during the construction period and associated with the long-term

establishment of development may increase fauna fatalities

• physical attributes of housing and associated significant infrastructure may obstruct or

change views of existing natural features considered aesthetically significant. The housing and

associated infrastructure may, in itself, be aesthetically displeasing.

Management of the potential impacts to visual amenity are discussed in Section 7.


The environmental objectives, targets and KPIs for the Leeuwin-Naturaliste National Park are detailed

in Table 13 below.

Table 13 Environmental objectives, targets and indicators for the Leeuwin-Naturaliste

National Park


To ensure that clearing is as approved for the Scheme Amendment and as outlined in the Fire Management Plan.

No clearing or disturbance outside of pre-defined boundaries within the scheme amendment and fire management area, during construction.

6. ABORIGINAL HERITAGE MANAGEMENT

6.1 DESCRIPTION

One registered Aboriginal site, DIA ID #21930 Gracetown Burial, Midden and Massacre Site lies

within the proposed residential development area. The site was previously identified in three studies

of the Gracetown region and identified by the Aboriginal heritage report (Fisher 2008) carried out for

the scheme amendment area. Whilst this area is considered of significant Aboriginal heritage value by

the authorised representative of the relevant Native Title claimants groups, Fisher (2008) states that

this recorded location may represent an amalgam of various components that may have already been

registered separately. Additionally, the coordinates are listed as ‘unreliable’ by the Department of

Indigenous Affairs (DIA).

The archaeological survey, carried out as part of the Aboriginal heritage report (Fisher 2008) also

identified a shell midden and some mounds, which may represent burial mounds located near the

football ground and not within the proposed residential development

Non-registered heritage sites (exact location undefined) have also been identified within the

Gracetown region, where artefactual material may exist below ground.

A more detailed description of the Aboriginal heritage of the scheme amendment area is contained in

Chapter 3, Section 5 of the ER.


The following aspect of the scheme amendment area development has been identified as requiring

management to minimise effects on Aboriginal and cultural heritage values:

• earthworks and installation of infrastructure during construction may disturb known and/or

unknown heritage sites and affect ethnographic values.


The environmental objectives, targets and KPIs for Aboriginal heritage management are detailed in

Table 17 below.


LAN10072_EMP_VA2 - 10/12/2012 32

7. VISUAL AMENITY

7.1 DESCRIPTION

The landscape values of the scheme amendment area were assessed by Ecoscape (2009) in terms of

their biophysical character and socio-cultural character. The surrounding area is characterised by the

steep natural topography with mostly unbroken ridgelines, crescent-shaped bay and the existing

Gracetown settlement.

Development of the scheme amendment area has the potential to affect the visual amenity of the area

by altering the landscape values of the site. The landscape values of the scheme amendment area may

be affected if the development significantly alters view (e.g. “skylining” of buildings above the natural

ridgeline where there wasn’t previously) or if the building design or materials are aesthetically

incompatible with the landscape values.


The following aspects of the scheme amendment area development have been identified as requiring

management to ensure they do not adversely impact natural landscape values:

• Clearing vegetation will alter the appearance of the natural environment which may be visible

from identified significant sites

• Physical attributes of housing and associated significant infrastructure may obstruct or

change views of existing natural features considered aesthetically significant. The housing and

associated infrastructure may, in itself, be aesthetically displeasing.

The clearing of vegetation is covered in the Biodiversity Management Plan (Section 3).


The environmental objective for visual amenity is:

• to create a new built environment in harmony with the natural elements of the landscape.


Specific mitigation measures have been identified to assist in achieving the visual impact objective

(Table 21).

8. WASTE MANAGEMENT

8.1 DESCRIPTION

Development of the scheme amendment area will generate waste both during construction (e.g.

building materials, fuel rags) and from habitation of the residential lots (e.g. general domestic waste).

Both waste streams have the potential to result in detrimental impacts on the environment and as such,

will require specific management.


The following aspect of the scheme amendment area development has been identified as requiring

management to ensure that waste generation does not adversely impact environmental values:

• disposal of wastes generated during construction and by residential occupants.


The environmental objectives, targets and KPIs for waste management are detailed in Table 22 below.

9. SOIL CONTAMINATION MANAGEMENT

9.1 DESCRIPTION

Development of the scheme amendment area may expose potential soil contaminants during the

planning and construction phase including asbestos. A baseline contamination investigation of the

scheme amendment area has been conducted and evidence of fly tipping has been identified in the

northwest corner of the scheme amendment area containing some small pieces of asbestos cement

(GHD 2009).

The presence of soil contaminants has the potential to present an environmental and/or human health

risk in the immediate area and potentially to neighbouring properties if the contaminants spread which

will greatly increase the cost of investigation and remediation. The Contaminated Sites Act 2003

(Contaminated Sites Act) is the main mechanism for identifying and managing known and suspected

contaminated sites. The Contaminated Sites Act requires owners or occupiers of a site, such as the

scheme amendment area, to report known or suspected contaminated sites to the DEC.

Prior to construction of the proposed residential development, investigations will be conducted in the

area identified as receiving fly tipping in accordance with the Guidelines for the Assessment,

Remediation and Management of Asbestos Contaminated Sites in Western Australia (DoH 2009) and

the DEC Contaminated Sites Management Series Guidelines to assess the degree of soil contamination

and recommend appropriate remediation actions (if required).



management to ensure the development does not pose a health related and/or environmental risk due

to the presence of soil contaminants:

• site clearing and earthworks to level-off certain areas of the site for later residential

construction

• disposal of waste during the construction phase of the scheme amendment area development

Site clearing and earthworks may expose potential soil contaminations at levels that exceed

contamination guideline levels and require remediation measures to prevent further health related

and/or environmental impacts. Disposal of waste during the construction of the development has the

potential to contaminate the site unless disposed of appropriately.


The environmental objectives, targets and KPIs for soil contamination management are detailed in

Table 26 below.

Table 26 Environmental objectives, targets and indicators for soil contamination

10. DUST MANAGEMENT

10.1 DESCRIPTION

Construction activities, such as clearing and earthworks, and general vehicle movements on unsealed

roads in and around the scheme amendment area are likely to increase the risk of atmospheric dust

emissions. These emissions may result in off-site environmental impacts and public concern,

particularly when activities are undertaken close to residences (in some cases it will be adjacent to

existing houses along Langley Crescent). Dust also has the potential to smother vegetation close to

the dust source and irritate fauna.

The majority of the airborne particles associated with dust emissions from construction activities are

likely to be larger than PM10 and are associated with nuisance rather than public health problems.

Furthermore, the larger particles tend to settle back to the ground within a short range (<300 m) from

the source, thereby reducing the potential impact.

The risk of activities resulting in off-site dust emissions is generally dependent on:

• the frequency at which a dust generating activity takes place

• meteorological conditions, such as wind speed and direction

• composition of dust, including particle size distribution, particle density and moisture content

• the condition of the source.



management to ensure dust emissions do not affect the amenity of nearby dust-sensitive premises:

• physical disturbance of the land surface during clearing and earthworks

• vehicle movement on unsealed roads and movement of heavy vehicles with uncovered loads

• wind erosion of dry exposed surfaces such as cleared areas prior to the establishment of housing

and ground cover.


The environmental objectives, targets and KPIs for dust management are detailed in Table 30 below.

Table 30 Environmental objectives, targets and indicators for dust


To minimise the effect of dust generated by construction activities on the amenity of nearby residents.

No public complaints relating to dust generated during construction activities.

No obvious and unacceptable deposition observed off-site.

11. NOISE MANAGEMENT

11.1 DESCRIPTION

Noise has the potential to be of nuisance to nearby residents; the closest residences being those

adjacent to Langley Crescent which is the northern boundary of the scheme amendment area. Noise

will be generated by activities associated with clearing and earthworks, as well as construction of

residences within the scheme amendment area. Noise from these activities at sensitive receptors can

be further exacerbated by certain meteorological conditions, such as atmospheric temperature

inversions and the speed and direction of wind.

The assigned noise levels in the Environmental Protection (Noise) Regulations 1997 (Noise

Regulations) do not apply to construction activities carried out between 0700 and 1900 hours on any

day except Sunday and public holidays provided:

• construction work is carried out in accordance with Section 6 of the Australian Standard 2436-

1981 “Guide to Noise Control on Construction, Maintenance and Demolition Sites”

• the equipment used is the quietest reasonably available

• the CEO of the Shire of Augusta-Margaret River may request that a Noise Management Plan be

submitted for the construction work at any time.

Activities outside normal working hours (0700 and 1900 hours on any day except Sunday and public

holidays) will be undertaken in accordance with the a Noise Management Plan approved by the Chief

Executive Officer or delegate (in this case the Shire of Augusta-Margaret River).



management to ensure noise emissions from the development do not affect the amenity of nearby

noise-sensitive premises:

• site clearing and earthworks to level-off certain areas of the site for later residential

construction

• construction of residences including minor excavation for foundations and transport of

materials.

Construction activities may result in minor increases in traffic noise on roads leading to the scheme

amendment area, and may cause localised temporary disruption to fauna in areas adjacent to the site.

However, increased noise emissions will be temporary.


The environmental objectives, targets and KPIs for noise management are detailed in Table 34 below.

• identification of their legal obligations.


LAN10072_EMP_VA2 - 10/12/2012 49

12.2 ENVIRONMENTAL INCIDENT REPORTING

Environmental incidents are events or occurrences that result in, or have the potential to result in,

unacceptable impacts to the environment, for example unauthorised clearing of vegetation and

vehicles deviating from designated roads and access tracks.

Environmental incidents include any breaches or non-adherences to objectives and procedures

prescribed in this EMP and other environmental management procedures applied to the site by

LandCorp.

All incidents will be reported on an Environmental Incident Report form and/or registered in an

electronic database. Incidents will be tracked to ensure that the appropriate corrective actions and

measures are taken to prevent the incident from reoccurring. Environmental incidents will be

reviewed on a monthly and annual basis to determine incident trends. This will enable targeting of

areas that require further management and will assist in preventing future incidents.

Environmental incidents shall be assigned a level of severity. Levels are yet to be finalised, however,

proposed levels may be as follows:

LEVEL 1: Minor non-adherence to procedure and/or a negligible environmental impact.

LEVEL 2: Minor non-adherence to procedure and minor environmental impact that requires little

management to be rectified.

LEVEL 3: Moderate breach of procedure and/or an environmental impact that requires management/

mitigation to be rectified.

LEVEL 4: (Serious incident) Extreme breach of procedure and/or environmental impact that could

lead to a breach of environmental approval conditions.

The proposed procedures to follow in the event of an environmental incident are listed in Table 38 and

vary depending on the level of incident occurring.

Table 38 Proposed environmental incident procedures

Procedure Responsibility

1. The incident shall be reported to the Contractor Supervisor/Foreman or the Contractor Environmental Control Officer as soon as practical. Whichever of the two is notified first, shall contact the other.

Person responsible or first on the scene

2. The level of environmental incident shall be determined. This may be up/down graded later depending on further advice from LandCorp, its consultants or government agencies.

CECO*

3. LandCorp shall be advised within 24 hours of a Level 2 incident and as soon as practicable within four hours following a Level 3 or 4 incident.

12.3 PUBLIC COMPLAINT RESOLUTION

A Public Complaint Register System will be operated to maintain a system of records that provide full

documentation of complaint handling.

The following will be recorded in the event that a public complaint is received:

• the date and time of the complaint

• the name of the person who received/recorded the complaint

• the method by which the complaint was made (e.g. phone, letter)

• personal details of the complainant

• the nature of the complaint

• the action to be taken in relation to the complaint and the person/s responsible for taking that

action

• potential for environmental incident.

Following investigation of the complaint, the Public Complaint Register System will be updated to

include:

• an outline of the investigations undertaken

• the action taken in relation to the complaint (including supplementary monitoring and corrective

actions)

• the reason for any decisions of inaction

• time and date of follow-up contact and resolution with the complainant

• the nature of, and outcomes from, follow-up contact with the complainant

• environmental incident report number (if applicable)

• any other details relevant to the complaint.

If the investigation of a complaint concludes that the nature of the complaint justifies its inclusion as

an Environmental Incident, it will be promptly acted upon according to the procedure outlined in

Section 12.2.

12.4 STAKEHOLDER CONSULTATION

LandCorp will seek advice and comment from the Shire of Augusta-Margaret River and DEC during

the finalisation of the various components of this EMP. LandCorp will continue to consult with the


LAN10072_EMP_VA2 - 10/12/2012 51

wider community regarding the development by providing information on their website and through

regular newsletters.

A Sustainability Review Committee and a Design and Sustainability Guidelines Audit Group will be

formed with a membership comprising community members, LandCorp and Shire of Augusta-

Margaret River representatives. The Committee will be responsible for:

• reviewing the effectiveness and relevance of the Design and Sustainability Guidelines and

implementation of the Sustainability Framework

• making recommendations to the Shire of Augusta-Margaret River for modification and

improvement, with particular reference to sustainability initiatives

• audit compliance with the fire management plan.

The Group will be responsible for:

• providing advice to prospective lot purchasers in respect to the Design and Sustainability

Guidelines

• assessing development applications for compliance with the Design and Sustainability

Guidelines, and providing the Shire of Augusta-Margaret River with an audit report.

The Committee and Group will provide another consultation avenue for the major stakeholders

associated with the residential development area.

12.5 AUDITING

LandCorp will conduct internal audits of its contractors to ensure compliance with the relevant scheme

conditions and implementation of the management actions outlined in this EMP, or other relevant

documents. The Shire of Augusta-Margaret River may also conduct audits to ensure development of

the scheme amendment area is in accordance with Local Planning Scheme No. 1 text.

Persons responsible for environmental auditing shall be suitably qualified (e.g. accredited under

Registrar Accreditation Board Society of Australasia [RABQSA]).

Where auditing finds particular environmental management actions are not effective, the audits may

recommend changes to procedures.

12.6 REVIEW AND REVISION

This EMP shall be reviewed as required throughout the duration of the development. Upon review,

the document shall be revised and re-issued where appropriate. In addition, continued improvement of

the plan will occur in response to environmental incident resolutions, audit findings, monitoring

results, continuous improvement and changes in regulatory and corporate requirements.

The Shire of Augusta-Margaret River will be advised of any minor changes to the plan and provided

with the revised document. Major changes will not be undertaken without consultation with the Shire

of Augusta-Margaret River and DEC (where necessary).

and Building Demolition

DEC (2010)

PROCEDURES TO MINIMISE RISK TO WESTERN RINGTAIL POSSUMS

DURING VEGETATION CLEARING AND BUILDING DEMOLITION

(June 2010)

IMPORTANT: Contact DEC Busselton on 9752 5555 prior to clearing commencing.

These procedures are generally for development activities that occur on smaller lots (<2ha). The

clearing of vegetation on larger lots should be discussed with DEC.

Identify trees to be retained

Clearing of native vegetation within the proposed development site should avoid any unnecessary

clearing of trees. Trees retained within the development site, proposed Public Open Space and within

road verges provide valuable habitat for WRP. Trees to be retained should be marked so that they are

clearly recognised by clearing contractors.

Suitable expertise on-site

A suitably experienced zoologist or WRP rehabilitator (‘possum spotter’) should be onsite when

clearing is being undertaken, that is, during the entire duration of the clearing. The ‘possum spotter’ is

to provide advice and direction to contractors undertaking the clearing in relation to WRP matters.

The contract manager or supervisor is the person responsible for all work undertaken and the safety of

all personnel on site at all times.

It is suggested that the ‘possum spotter’ attend the site the day before clearing commences to be

familiar with the location of any WRP and dreys. A person who is required to handle WRP during a

clearing event that is part of development proposal should hold a Regulation 17 (scientific) licence.

Advice to clearing contractors

Prior to clearing, clearing contractors should be properly inducted by the ‘possum spotter’ about the

identification and protection of trees to be retained, trees to be cleared and about the likely presence of

WRP among trees and other vegetation that will be cleared. No dogs should be taken on the site.

Tree removal

The ‘possum spotter’ with the clearing supervisor is to inspect all trees to be removed and agree on a

process and timetable for clearing. Trees that have WRP currently in them may need to be left for a

subsequent day when the tree may be vacant. Where possible clearing should be undertaken in a

systematic manner that minimises disruption to WRP. If there is suitable habitat adjoining the

development site, a clearing pattern that encourages the movement of WRP to this habitat should be

adopted.

In moderate or high-density sites, if a machine operator sees a WRP in a tree that is about to be

cleared, trees should be bumped or shaken firstly. Following this the machine operator should wait

and observe the tree for a short time. If present, the shaking of the tree may cause any WRP and other

fauna to move and, hopefully, opportunity to safely evacuate. It would also increase the chance that

the machine operator will see the animal/s prior to pushing down the tree.

In the event that a WRP is observed in a tree that is about to be cleared and there is a tree marked for

retention near the tree which is to be cleared, then the tree should be gently lowered to the ground to

give the animal opportunity to safely evacuate. The animal/s then need to be encouraged to move

towards and occupy the trees to be retained.

If there are no trees to be retained within proximity of a tree that has a WRP and needs to be cleared,

then the WRP can be removed by the ‘possum spotter’ using an elevated platform or by lowering the

tree to the ground. The WRP is to be relocated to the nearest suitable habitat.

Dreys should be inspected prior to clearing and possibly removed. Dreys that remain in the tree

during clearing have to be checked as soon as possible as baby WRP may remain in the drey.

Clearing should be undertaken on a face so as to drive WRP towards suitable habitat.

Services

The proponent will need to identify where underground services are to be installed and to ensure any

detrimental impact from these services is minimised.

Understorey vegetation

There will always be a possibility that WRP, Southern Brown Bandicoots, etc, will be found in under

and midstorey vegetation. Care needs to be taken when clearing this vegetation with a check to be

undertaken by foot prior to machines entering the areas and clearing this vegetation.

Injured WRP

If contractors encounter injured WRP during clearing operations, then the ‘possum spotter’ needs to be

notified immediately so that arrangements can be made for the welfare of the injured animal.

Stockpile practices

Contractors need to be made aware that displaced WRP may shelter within stockpiled vegetation.

Therefore, to minimise any accidental injury or death of WRP, personnel involved in the removal or

disposal of stockpiles need to be made aware of and be prepared for the potential presence of WRP. If

WRP are encountered then the Department needs to be immediately notified. Any dreys in fallen trees

are to be removed prior to stockpiling as WRP have been known to return to their dreys/trees.

The preference is that vegetation is not stockpiled but removed on the same day clearing occurs. If

vegetation is to be stockpiled on-site, then it is preferable to place it in cleared areas as far as possible

from retained remnant vegetation. Chipping of removed debris is to be undertaken away from retained

habitat to minimise the noise impacts on WRP.

In large clearing events where chipping will be undertaken over a number of days, it is preferred that

the chipper remains in one position and vegetation is brought to the chipper as opposed to the chipper

moving through the site. This is to consolidate the noise impacts in one area of the development site.

Buildings

Site workers are to be advised about the potential presence of WRP in derelict buildings and to stage

works to minimise potential injuries to WRP during demolition works. Prior to clearing works

commencing, the roof and ceilings on derelict buildings should be removed prior to demolition to

allow for dispersal of WRP. DEC should be immediately notified of any WRP that may be

inadvertently injured during demolition works.

There is a risk to WRP if rat or mouse baiting is undertaken prior to demolition. Appropriate methods

of baiting need to be engaged if rats or mice are to be controlled prior to demolition. One method is to

place the poison out of WRP reach, inside poly pipe secured to a beam in the roof space. The pipe

should be about 1m long and no greater than 50mm in diameter. Another method is to place a plastic

ice-cream container upside down over rate poison with small arches cut into the side of the container.

The arches should be a maximum height and width of about 50mm and the container secured to a

rafter.

Post Clearing Reporting

The proponent is to provide DEC with a report on the impact on WRP during the habitat removal

process within 28 days of completion of vegetation clearing or building demolition works.
