Introduction

The Building Development Group Pty Ltd commissioned 360 Environmental Pty Ltd (360 Environmental) to prepare a Foreshore Management and Landscape Plan (FMLP) for the proposed subdivision of Lots 104 and 105 BusseII Highway, Margaret River (the Project).

The Project area is located approximately two kilometres south of the Margaret River townsite on the western side of BusseII Highway (Figure 1). The Project area is traversed by two defined watercourses.

_P P u r p o s e a n d S c o n e o f Works

The Western Australian Planning Commission (WAPC) requires that a FMLP be provided prior to lodgement of subdivision. The purpose of the FMLP is to outline the management strategies required to conserve and rehabilitate the natural riparian environment of the two watercourses in the Project area while allowing access for community recreational use and appreciation of the natural area within the residential development.

The objectives of the FMLP are to:

CD Protect and conserve the natural values of the foreshore including vegetation, fauna habitats and water quality;

Promote the foreshore as a conservation, recreation and education resource for the use and enjoyment of the community;

GI Provide a strategy for the management of existing vegetation and implementation of a rehabilitation and landscape plan; and

Increase community awareness and understanding of the value of foreshores and the issues associated with their management.

2 Exist ing Information

The climate of the Project area is warm Mediterranean with warm summers and cold winters. Weather data from the Witchcliffe station located 8.1 kilometres (km) south of Margaret River over 17 years records the annual mean maximum temperature of 21.5°C and the annual mean minimum temperature at 10.7°C. The mean annual rainfall was recorded at 947.4 millimetres (mm) (Bureau of Meteorology 2016).

a l i d L a r l u t o r Tr, The 1:50 000 Cowaramup — Mentelle Regolith Mapping (DMP 2000) indicates the geology of the Project area is typically as follows:

• Colluvial. Undivided slopes silty of gravelly sand over mottled sandy clay;

Leeuwin Complex. Fresh to weathered, undivided felsic granulite and granite; minor mafic granulite and anorthosite; and

O Creek Areas - Alluvial. Stream channel; includes stream bed and banks (Figure 2).

The Project area contains two land units within the Cowaramup Land System (Tille and Lantzke 1990). These are described below:

O COu Cowaramup, undifferentiated upland phase land system: lateritic flats, low rises and gentle slopes: loamy gravels, duplex sandy gravels, semi-wet soils and

grey deep sandy duplexes: marri-jarrah forest and woodland; and

• COvw Cowaramup subsystem, wet vales phase land system: broad, swampy floored drainage depressions: wet and semi-wet soils, grey deep sandy duplexes, loamy gravels and duplex sandy gravels; marri-jarrahpaperbark- teatree woodland and forest.

Geotechnical investigations undertaken by Douglas Partners (2006) from test pits across Lots 104 and 105 describes the alluvial soil deposits of the waterways as very loose to loose, fine to medium grained, high plasticity, damp clayey sand and silty clayey sand between 0.3 metres (m) and 0.5 m.

The topography of Lot 105 is gently undulating from south-west to north-east. The topography of Lot 104 is generally flat. Elevations range between approximately 84 metres Australian Height Datum (mAHD) and 93 mAHD (JDA 2012).

360 environment:1,A

2 . 3 H y d r o l o g y e n d Drainage Two defined watercourses intersect the Project area. The first watercourse is a tributary of Darch Brook that starts in the south west of the Project area and flows in a north easterly direction. The second watercourse is a smaller creek that starts in the south east of the Project area and flows in a north easterly direction. The two watercourses eventually join in the south west portion of the Project area where surface water flows into a culvert under BusseII Highway (Figure 1).

Surface water discharge from the Project area flows through existing culverts under BusseII Highway and discharges into Brookfield Estate's drainage system, adjacent to the Project area (JDA 2012).

Acid Sulfate Soil (ASS) is the common name given to naturally occurring soil and sediment containing iron sulfides. When disturbed and exposed to air, however, they oxidise and produce sulfuric acid, iron precipitates, and concentrations of dissolved heavy metals such as aluminium, iron and arsenic. Release of acid and metals as a result of the disturbance of ASS can cause significant harm to the environment and infrastructure.

The Department of Parks and Wildlife (DPaW) and the Western Australian Planning Commission (WAPC) have released guidance notes on ASS, covering the requirement for assessing sites and the management of sites where ASS are identified (WAPC 2003).

The majority of the Project area has no known risk of ASS within 3 m of natural surface. The area directly adjacent to the watercourse within Lot 105 is classed as having a moderate risk of ASS within 3 m of natural surface (JDA 2012). An ASS investigation Cardno (2010) was broadly consistent with WAPC (2003) mapping, finding the presence of soils with existing acidity identified in soils containing iron associated rock fragments (laterite and ironstone) in areas of lower site elevation

The Project area is part of the Boranup vegetation system, situated in the Warren Botanical Sub-district of the South West Botanical Province (Beard 1981). Native vegetation within the Project area is mapped as:

C) Association 3: Medium Forest; jarrah-marri (Shepherd et al. 2001) (Figure 2).

The regional representation of each vegetation association has been compiled from the Government of Western Australia (2014) 2014 Statewide Vegetation Statistics. The current extent of Association 3 is presented in Table 1.

The Environmental Protection Authority (EPA) aims to retain ecological communities at a minimum of 30% of the pre-clearing extent of that community in a bioregion to meet the National Objectives and Targets for Biodiversity Conservation 2001-2005 (Commonwealth of Australia 2001) (EPA 2008). Vegetation Association 3 is retained at more than 30% of the pre-clearing extent.

The vegetation types and condition recorded in the foreshore area (Onshore Environmental Consultants 2006) are outlined below in Table 2.

A list of native and non-native flora species occurring on site has been recorded and compiled (Appendix A). No flora protected under the Wildlife Conservation Act 1950 have been recorded in the Project area (Onshore Environmental Consultants 2006). One flora species listed as Priority 4, Bossiaea disticha was collected from the Project area. Priority 4 species are defined by DPaW as:

Rare, Near Threatened and other species in need of monitoring

(a) Rare. Species that are considered to have been adequately surveyed, or for which sufficient knowledge is available, and that are considered not currently threatened or in need of special protection, but could be if present circumstances change. These species are usually represented on conservation lands.

(b) Near Threatened. Species that are considered to have been adequately surveyed and that are close to qualifying for Vulnerable, but are not listed as Conservation Dependent.

(c) Species that have been removed from the list of threatened species during the past five years for reasons other than taxonomy (DPaW 2015).

A total of 22 weed species have been recorded in the Project area (Eco Logic Environmental Services 2011) (Table 3). Three weed species, *Asparagus asparagoides, *Rubus ulmifolius and *Zantedeschia aethiopica and listed as Declared Plants under the Biosecurity and Agriculture Management Act 2007 (the BAM Act) (WA) and one weed species, *Asparagus asparagoides, is listed as a Weed of National Significance (WONS) by the Australian Government.

Declared pests must satisfy any applicable import requirements when imported, and may be subject to an import permit if they are potential carriers of high-risk organisms. They may also be subject to control and keeping requirements once within Western Australia. Under the Biosecurity and Agriculture Management Act 2007 (the BAM Act), all declared pests are placed in one of three categories, namely C l (exclusion), 0 2 (eradication) or 0 3 (management). C l category (Exclusion) - Pests will be assigned to this category if they are not established in Western Australia and control measures are to be taken, including border checks, in order to prevent them entering and establishing in the State. 0 2 category (Eradication) — Pests will be assigned to this category if they are present in Western Australia in low enough numbers or in sufficiently limited areas that their eradication is still a possibility. 0 3 category (Management) — Pests will be assigned to this category if they are established in Western Australia but it is feasible, or desirable, to manage them in order to limit their damage. Control measures can prevent a 0 3 pest from increasing in population size or density or moving from an area in which it is established into an area which currently is free of that pest (DAF 2016)

360 envronmentb:

The Preliminary Environmental Assessment (Onshore Environmental Consultant 2006) recorded three senescent trees occurring in the south-west corner of the Project area which are considered to be hazardous owing to a significant north lean. Building envelopes should be positioned outside of the potential trees (Onshore Environmental Consultant 2006). These trees may require an assessment of whether they are hazardous within the foreshore reserve area.

The Project area contains remnant native vegetation that is likely to provide habitat for a range of fauna species including the following conservation significant fauna:

O Western Ringtail Possum (Pseudocheirus occidentalis) (listed as Endangered under the Wildlife Conservation Act 1950 (WC Act) (WA) and Vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) (C'wth);

• Carnaby's Cockatoo (Calyptorhynchus latirostris) (listed as Endangered under the WC Act (WA) and EPBC Act (C'wth));

• Baudin's Cockatoo (Calyptorhynchus baudinii) (listed as Endangered under the WC Act (WA) and Vulnerable under the EPBC Act (C'wth)); and

O Forest Red-tailed Black Cockatoo (Calyptorhynchus banksii naso) (listed as Vulnerable under the WC Act (WA) and EPBC Act (C'wth).

The Project area contains stands of Agonis flexuosa (Peppermint Tree), Eucalyptus marginata subsp marginata (Jarrah), Eucalyptus diversicolor (Karri) and Corymbia calophylla (Marri) (Environmental and Landscape Management 2013). Western Ringtail Possum populations have been known to be associated with the presence of Peppermint Trees (DotE 2016). Surveying of the Project area for the presence of Western Ringtail Possums was undertaken between October and December in 201 3 (Environmental and Landscape Management 2013). No evidence of Western Ringtail Possum activity was recorded in the Project area (Environmental and Landscape Management 2013).

Stands of Eucalyptus marginata subsp marginata (Jarrah), Eucalyptus diversicolor (Karri) and Corymbia calophylla (Marri) provide foraging, roosting and breeding habitat for the three species of Black Cockatoos. Trees with suitable nest hollows or a Diameter at Breast Height (DBH) of 500 millimetres (mm) or more are known to support breeding (DSEWPAC 2012). 59 trees were identified in the Project area as having a DBH of 500

mm or more (Environmental and Landscape Management 2013) (Figure 3). Hollows within these trees were inspected by qualified personnel for breeding activity. No breeding activity was observed at the time of inspection (Environmental and Landscape Management 2013).

C o n s e r v a t i o n Areas

The nearest conservation area is Bramley National Park located approximately two kilometres north east of the Project area (Figure 4). South West Regional Ecological Linkages throughout the south west of the State have been mapped by DPaW and the Western Australian Local Government Association (WALGA) (2009). The Project area does not occur within a mapped Regional Ecological Linkage. The Rails to Trails reserve is a linear strip that runs perpendicular to the western boundary of the Project area. This is an informal reserve that is yet to be placed in a conservation estate to be managed under the Conservation and Land Management Act 1984 (CALM Act). The reserve contains larger areas of remnant vegetation. The retention of remnant vegetation within the Project area may improve habitat linkages for wildlife through to the adjoining Rails to Trails Reserve.

C u r r e n t C o n d i t i o n o f ForeshorR

The condition of the watercourse foreshore has been assessed using the Pen-Scott method of riparian zone assessment (Pen and Scott 1995) (Appendix B). The assessment was undertaken on the main channel of the foreshore proposed to be retained. The Pen-Scott method provides a graded description of the watercourse foreshore which grades from Pristine (A grade) through to a Ditch (D grade). The foreshore of the watercourse was assessed as being in both B Grade and D Grade condition (Table 4).

Table 4: Pen-Scott System of Foreshore Condition Rating (Eco Logic Environmental Services 2011) (Figure 5)

B GRADE FORESHORE

Environmental Protection Authority (2008) Environmental Guidance for Planning and Development-Guidance Statement No. 33 (Attachment 85-1 Determining foreshore reserves).

Riparian vegetation along this section consists of scattered native sedges to a width of approximately 2 to 10 m either side of the creek channel corresponding with the drainage landform

Valuable habitat areas are contained with the vegetated western section of the creekline with native vegetation recorded to be in Very Good and Degraded to Good condition

Highly modified with only scattered trees and few native understorey species remaining

Extent of riparian vegetation could not be assessed in this

area

The creekline channel has become unstable in this section through trampling by livestock, undercutting from water action and bank subsidence. Livestock grazing has caused substantial soil erosion through this area lowering the surface ground level. The channel has subsequently widened and deepened as a result of the erosion. This action is causing the undermining of several trees along the bank and contributing nutrients and sediments to waterways downstream. There are small pockets of the creekline channel remaining through this area that are approximately 1- 2 m in width

The biophysical assessment concluded that a 20 m creekline buffer (10 m either side of the creek channel) will encompass all areas of riparian vegetation, some areas of upland vegetation and the floodplain landform on both sides of the creekline. The buffer will protect habitat while providing erosion control and nutrient stripping, with the potential to improve the habitat quality and functions of the buffer through foreshore restoration.

The modification of the central and eastern sections of the creekline will require re- contouring of the creekline channel and river restoration works including revegetation. The restoration works within the proposed 20 m creekline buffer would improve and adequately protect the ecological values of the waterway (Eco Logic Environmental Services 2012).

V e n e t F y t i n n MannqRmPnt

Native vegetation within the Project area will be protected through the retention of a 20 m wide creekline buffer and 0.33 hectare (ha) of remnant native vegetation in the north west portion of Lot 105 (Figure 5).

Retention of 0.33 ha of native vegetation in the north west portion of Lot 105 will protect Western Ringtail Possum and Black Cockatoo habitat and may improve habitat linkages for wildlife through to the adjoining Rails to Trails Reserve. This vegetation will be retained as common property.

Native vegetation will be planted within the creekline buffer and retained where possible, improving habitat and maintaining erosion control and nutrient stripping functions. The foreshore reserve area is to be incorporated into the POS amenity and integrated with the flood management system. The smaller creekline starting in the south east of the Project area is proposed to be piped through to a bio-retention basin.

3 . 1 . 1 R e h a b i l i t a t i o n o f t h e F - o r e s h o r e Reserve

Existing riparian vegetation within the 20 m wide creekline buffer is in a degraded state in some areas due to weed invasion and historical land uses such as clearing and stock grazing. For the purposes of this plan, the foreshore has been divided into two zones to reflect the variation in foreshore conditions (Figure 5). These zones will vary in the:

0 Management objectives of the zones;

O Vegetation condition and foreshore condition rating;

O Species and density of planting required for revegetation; and

O Weed management.

Zone 1 is the western section of the creekline buffer that has been classified using the Pen-Scott method as B3:Degraded-Weed Dominated (Figure 5). Given that the zone contains native vegetation already, rehabilitation will focus on undertaking weed control to reduce the presence of weeds and allow for the natural regeneration of native species. Where natural regeneration is low, minor infill planting may be undertaken. All native vegetation in this zone will be retained and protected during weed control. It should be noted that patches of native grasses including Spear grass (Austrostipa sp.) and Wallaby

grass (Austrodanthonia sp.) were recorded along the creekline banks in this zone. These native grasses are likely to appear to be grass weeds to a weed control operator and will need be flagged and protected from weed control measure

Zone 2 in the central and eastern sections of the creekline buffer has been classified using the Pen-Scott method as D l : Ditch-Eroding (Figure 5). This area has been highly modified by past landuse.

Zone 2 will require weed control measures and extensive planting of local native seedlings to restore the riparian habitat. Apart from pasture grasses, the only significant weed species in this Zone were Blackberry bushes (*Rubus ulmifolius) on the north side of the creekline.

Fringing vegetation plays an important role in maintenance of a biologically balanced and healthy waterway. The restoration of the riparian vegetation in this Zone through weed control and revegetation will improve biodiversity and wildlife habitat values, as well as providing bank stability, sediment and nutrient retention and improved water quality.

The majority of the weed species were recorded in Zone 1 in the vegetated western section of the creekline. Three weed species are listed as Declared Plants including Blackberry (*Rubus ulmifolius), Arum Lily (*Zantedeschia aethiopica) and Bridal Creeper (*Asparagus asparagoides). The removal and/or control of these three weeds

are considered to be a priority.

A weed control program is recommended with resources focused towards eradicating or controlling the introduced species that have the greatest potential to invade other areas and complete with native species. To facilitate natural regeneration of native species, weed control will need to be implemented for a minimum of two years. Follow up weed control (including spot spraying and isolated hand removal) should be continued for at least another two years following initial weed control to avoid the re-establishment of weed species (particularly the Declared Plants).

Weed control should be undertaken by appropriately trained operators following the correct usage, storage, handling and safety instructions on the herbicide labels. Incorrect application of herbicides near waterways has the potential to cause harmful effects to non-target organisms such as frogs, fish and other aquatic life. The following guideline should be considered when planning to use herbicides near waterways:

Water Cooperative Research Centre for Australian Weed Management Herbicides: Guidelines for Use in and Around (2005).

Weed control in Zone 1 will require a mix of hand-removal, cutting and pasting with herbicide and targeted spot spraying to minimise impacts on the remnant native vegetation. Weed management in the open areas of pasture grasses in Zone 2 can include a more broad-scale herbicide treatment. It is recommended to spray the appropriate herbicide in strips along the contour and leave some strips of exotic grasses

360 environment-al

unsprayed to reduce the potential for erosion of the stream channel and bank. These

areas can be designated for weed control in the second year and subsequent in-fill planting with local native species. Refer to Appendix C for weed control methods for the weed species identified in the foreshore reserve.

Revegetation will be required at different densities within Zone 1 and 2 in the foreshore

reserve. Following earthworks, the flood attenuation area will be in a degraded state requiring extensive revegetation. The rehabilitation of this area will require consultation

on species and planting densities with the project engineer when the Urban Water Management Plan (UWMP) for the Project area is finalised.

The vegetated area of Zone 1 will require some infill planting of shrubs and groundcovers after targeted weed control measures have been implemented. Infill planting in between bare areas will stabilise the soil surface, prevent weed recolonisation and provide fauna habitat. Zone 2 has been highly modified and will require extensive planting of all levels of the stratum including trees, shrubs, sedges, rushes and groundcovers. The planting of dense riparian vegetation along the foreshore in Zone 2 will serve to dissipate the energy of the water reducing the erosive capacity of the flow, improve water quality and enhance ecological values.

Planting is the most appropriate technique for embankments and in-stream vegetation, where direct seeding is difficult due to excessive weed competition and water flows. The revegetation techniques for the foreshore area are outlined below:

O Local native species will be used in the areas requiring rehabilitation;

O Seedlings will be grown in soil that is weed free so that no additional weed species are introduced to the foreshore area;

O Seedlings will only be planted in weed free areas;

O Seedlings will be planted in late autumn to early winter following winter rainfall;

O Seedlings should only be planted after initial rainfall has thoroughly moistened the soil;

• No fertiliser will be used at the time of planting;

O Seedlings will have tree guards installed to protect them from feral/pest animals grazing and pulling them out. Tree guards will not be used for sedges, rushes or other species to be planted in the stream channel;

O Care should be taken to ensure plants are randomly placed to achieve a natural effect; and

O It will not be necessary to water the plants on planting provided they are well watered before planting and the planting precedes good winter rainfall.

Appendix D lists the suite of local native species recommended for planting in the foreshore reserve. A typical cross section of the foreshore post-revegetation is provided in Figure 6. All tubestock will be obtained from nurseries accredited under the Nursery Industry Accreditation Scheme of Australia. Any tubestock that is unable to be supplied in the quantities required may be replaced with another native species.

O Plant and retain native vegetation within the 20 m wide creekline buffer (foreshore reserve) where possible;

O Retain all native vegetation within the 0.33 ha area to be retained as common property;

O Undertake weed control of Declared Plants, Blackberry (*Rubus ulmifolius), Bridal Creeper (*Asparagus asparagoides) and Arum Lily (*Zantedeschia aethiopica) as a priority;

O Flag and protect native vegetation within the foreshore area during weed control, particularly native grasses;

O Implement ongoing weed control for a least the first 2 years according to the appropriate methods outlined in Appendix C, including strip spraying in Zone 2 to prevent erosion;

O Spot-spraying with chemicals or physically removing isolated re-occurences of weed species will continue for at least 2 years to avoid the re-establishment of weed species, particularly Blackberry, Arum Lily and Pittosporum;

O All weed control should be conducted by a professional operator trained in the

use of herbicides;

O Implement the revegetation plan over two years using local native species and plant densities as outlined in Appendix D; and

O Undertake in-fill planting in the second year using local native species and densities as outlined in Appendix D.

. . - l ab i t a t Maintenance

The Project area is known to contain habitat that may potentially be utilised by threatened fauna including Black Cockatoos and the Western Ringtail Possum. Refuge and habitat for native fauna will be protected through the retention of native vegetation within the 20 m wide creekline buffer and portion of native vegetation to be retained as common property in the north west portion of Lot 105 (Figure 5). The retention of these

areas provides a linkage between native vegetation in the Project area and the Railway Reserve.

360 environment,a1

Creekline habitat elements such as rocks, fallen logs and in-stream woody debris provide habitat for aquatic fauna. These elements are also important to the stability and ecology

or creekline systems. Materials such as rocks, fallen logs and woody debris should be retained in the foreshore reserve where possible. Where these materials are unable to be retained they may be located or improved.

Where a tree is deemed unsafe to retain (due to a decline in the tree's health or death) these trees should be inspected by a qualified Tree Surgeon. The Tree Surgeon should develop a plan for pruning or removal of the tree with an emphasis on retaining the tree where possible.

Disturbance to fauna will be minimised through discouraging access directly adjacent to the creekline and areas of retained native vegetation. Pedestrians will be encouraged to stay on formal pathways. Signage should be provided to increase community awareness of fauna habitat within the area.

Prior to clearing activities, areas of native vegetation to be retained should be clearly demarcated by star pickets, coloured tape or bunting and personnel should be made

aware of the requirement to protect native vegetation in this area. No dead, standing or fallen timber should be removed unnecessarily. Logs (hollow or not) and other debris resulting from land clearing should be placed in retained vegetation to enhance fauna habitat.

Vegetation considered to be habitat for Black Cockatoos will be identified prior to clearing. Trees that have openings greater than 12 cm in diameter would be suitable for a Black Cockatoo to enter for nesting. Based on typical breeding and fledging times of Black Cockatoos, the best time to carry out clearing at the site would be in the months of April to June. Where clearing cannot be undertaken at this time, trees with hollows should be inspected by a suitably qualified wildlife consultant for the presence of breeding birds prior to clearing. If active Black Cockatoo nests are located in any of the hollows, the tree and nest will be left undisturbed until fledglings have left the nest.

Vegetation considered to be habitat for Western Ringtail Possums will be identified prior to clearing. A suitably qualified zoologist or 'possum spotter' will be on-site during any clearing operations. This person will provide advice to all personnel involved in clearing works and will report directly to and advise the contract manager or supervisor.

The 'possum spotter' will inspect any trees or vegetation that is proposed for clearing prior to any work commencing. Clearing works will be scheduled around the findings of the 'possum spotter'. Works may be delayed and re-scheduled to allow the Western Ringtail Possum to move out of the immediate area.

The 'possum spotter' will record all relevant information regarding the presence of Western Ringtail Possum during the clearing operations (including drey locations). This data will be formalised for submission to the DPaW within 28 days of the completion of the vegetation clearing or any building demolition works.

O Areas of native vegetation to be retained will be clearly demarcated prior to clearing;

O Black Cockatoo and Western Ringtail Possum habitat will be inspected prior to clearing;

O Where Black Cockatoos or Western Ringtail Possums are found to be utilising the Project area, works will be delayed or re-scheduled to allow these fauna to move out of the immediate area;

O Aquatic habitat such as fallen logs, woody debris and rocks will be retained for their habitat value where possible;

O Disturbance to fauna habitat will be prevented through education and the provision of formal pathways.

F e , r e l F ind D n m e s t i c AnimalF,

Given that the development is adjacent to large areas of native vegetation and farmland, it is possible that feral animals including rabbits, foxes and cats may be present. The removal of cats and foxes is not feasible considering the location of the Project area.

Rabbits have the potential to hinder revegetation efforts as well as disturbing the soil through digging creating an environment for weeds to proliferate. The total removal of rabbits from the Project area is not feasible, given the proximity to nearby suitable habitat, however seedlings can be protected from rabbit grazing through the use of tree guards.

In regard to controlling pets, community involvement and awareness promoting the control of pets such as dogs and cats is an important aspect of managing predation on native fauna. Dogs should be prohibited from uncontrolled access to the foreshore

reserve. Dog owners should have their dogs on a lead and use the proposed pathway system. Owners of cats should be encouraged to keep them in at night, and preferably at all times.

e m e n t Recommendations

GI Install tree guards on native seedlings on the creek bank and higher slopes of the creek channel;

O Permit Cat and Dog Ownership by residents in accordance with the Local Government Dog Act 1976 and other relevant Local Government regulations;

360 envtronmersal

Install community awareness signs for the impact of pets such as cats and dogs

on the local fauna in the natural environment.

DiebacK

Disease in natural ecosystems of Australia, caused by the introduced plant pathogen Phytophthora cinnamomi (Dieback), is listed as a key threatening process under the EPBC Act (C'wth). It is possible that Dieback may be present in native vegetation within the Project area. Precautionary management measures should be taken to prevent the introduction or spread of Dieback in the Project area.

' 3 . 4 . 1 1 v r r cTrrriJcr

• Strictly manage the movement of soils and plant material into the Project Area;

• Ensure all plant, machinery, vehicles and equipment is inspected immediately prior to entering the Project area to ensure it is free of weeds and soil; and

As far as practical, time the clearing phase of the operation to occur during the dry months to reduce the risk of spreading the disease.

3 . E A c i d S u l f a t e Soils

Risk mapping for the Project area in relation to Acid Sulphate Soils (ASS) indicates there is no risk within 3 metres of the existing ground level for the vast majority of the Project

area (J DA 2012).

Where excavation or dewatering is required below three metres of the ground level, an ASS investigation may be required in consistency with the Department of Environment Regulation (DER) (formerly the Department of Environment and Conservation) Identification and Investigation of Acid Sulfate Soils and Acidic Environments (DEC 2009).

The investigation should be followed by the development of an Acid Sulfate Soils and Dewatering Management Plan (ASSDMP) to appropriately manage the handling and treatment of ASS and dewatering effluent.

S u r f a c e W a t e r Management

There is a significant catchment which drains through the Project area from upstream for which flow paths will need to be maintained post development. A Local Water Management Strategy (LWMS) report has been produced by JDA Consultant Hydrologists (2012) for Lots 103-106 Bussell Highway, Margaret River.

The LWMS is required by the Western Australian Planning Commission (WAPC) to support the Outline Development Plan (ODP) and subsequent subdivision. The LWMS provides high-level drainage planning for the site and a recommended approach for total water cycle management consistent with sustainability principles.

The main creekline running south west to north east through Lot 105 will be rehabilitated

as a Living Stream with a bio-retention basin proposed in the north east corner of the Lot adjacent to the BusseII Highway. The creekline entering from Lot 106 to the south in the south-east section of the Project area is proposed to be piped underground into the bio- retention basin proposed for Lot 105.

Key elements of the ODP related to surface water management include:

O Rehabilitation of the existing waterways ultimately discharging to Margaret River via Brookfield Estate under BusseII Highway as living streams;

O Establishment of buffers for the future protection of the waterway and use of these areas for POS amenity and integration with the proposed flood management system;

O Use of ephemeral detention areas for management of local stormwater;

O Maintenance of flow paths for upstream catchment through the Project area; and

O Maintenance of existing discharge points from the Project area to the receiving environment; and housing is proposed for Lots 104 and 105.

An UWMP will be developed and submitted to DoW to support the subdivision application for various stages of the development in due course. The UWMP will provide detailed guidance on measures to be undertaken for management of surface water.

2 . 7 F i r e Menagement

A Bushfire Management Plan has been developed for the Project area (RUIC 2016). The Bushfire Management Plan has been prepared to satisfy subdivision requirements. The Bushfire Management Plan outlines bushfire minimisation measures and strategies that will provide adequate protection from wildfires.

The retention of native vegetation in the Project area as common property and foreshore

reserve requires consideration as a potential bushfire threat. Bushfire Attack Levels (BALs) have been calculated for the Project area to determine potential bushfire impact. The BAL analysis assumes that:

O Retained vegetation within the Public Open Space will either be landscaped and managed trees and lawn excluded from the BAL analysis under AS 3959 c2.2.3.2(f) or Class A Forest (whereby trees are between 10-30 m high, typically dominated by Eucalypts) and;

O The creekline buffer will be revegetated to Class C Shrubland (whereby shrubs

are to 1.5 m high and represent >30% foliage cover).

Under these assumptions, sufficient separation from future habitable buildings will

ensure a maximum BAL-29 rating is achieved (Figure 7). Maintaining a BAL rating of BAL-29 in the development will need to consider the following:

360 erivironme,-,LLI

O Bushfire Attack Levels (BAL) BAL-40 and BAL-FZ habitable building exclusion

zones will be implemented within lots with this rating to ensure that all habitable buildings will be constructed on maximum BAL-29 land;

• Understorey fuel within the 21 m buffer will be permanently removed and the

canopy will be opened up so that this area will be excluded from the BAL Analysis in accordance with AS 3959-2009 c2.2.3.2(f). The buffer must be permanently maintained in this low threat state

O Species used in landscaping design will be consistent with AS 3959-2009 c2.2.3.2(f) (low threat vegetation) to ensure vegetation does not contribute to bushfire intensity;

O Where areas of bushland are to be included as part of landscaping design, ensuring they are consistent with AS 3959-2009 c2.2.3.2(c) being less than 0.25 ha in area and not within 20 m of each other or proposed dwellings, or less than 1 ha in area and not within 100 m of other vegetation being classified (AS 3959 c2.2.3.2(b));

O Where strips of vegetation are to be incorporated into landscaping design, ensuring they are less than 20 m in width (measured perpendicular to the elevation exposed to the strip) and not within 20 m of the site, or each other, or other areas of vegetation being classified (AS 3959 c2.2.3.2(d)); and

O Utilising non-vegetated areas, such as roads, footpaths and waterways, within the development consistent with AS 3959-2009 c2.2.3.2(e) to provide enhanced separation between buildings and vegetation identified as a bushfire threat external to the site boundaries (RUIC 2016).

3 . 7 . 1 M e n a p e m e n t Recommencietions

O Select plant species for use in revegetation or landscaping with a height of no more than 1.5 m at full maturity;

O Ensure planting in the foreshore reserve does not occur within 7 m of proposed dwellings;

• Remove understorey vegetation and open canopy within the 21 m buffer; and

O Ensure 0.33 ha area of native vegetation to be retained as common property is not within 21 m of proposed dwellings.

R i v e r Restore/747)r

Due to disturbances including clearing, grazing and weed invasion the foreshore reserve area has been degraded. The creekline channel in the vegetated western section is stabilised (Zone 1), however the central and eastern sections (Zone 2) have become unstable through minor undercutting from water action and bank subsidence. The

channel has subsequently widened and deepened to adjust to the new amount of water volume. This action is causing the undermining of several trees along the bank and contributing nutrients and sediments to waterways downstream.

Unstable and degraded sections of the watercourse will be converted to living streams through revegetation. Planting of vegetation will stabilise banks and improve nutrient stripping and erosion control functions (refer Section 3.1). In some areas, revegetation of the creekline banks may not be possible due to the steepness of the slopes. In these

areas, other bank protection measures may be used such as brushing, rock pitching or jute matting. These measures will be incorporated into the final design of the living stream.

Re-contouring of the creekline channel will also be required in areas where the channel has become highly modified. Re-contouring will reinstate natural surface water flows and prevent erosion, sedimentation and nutrient input downstream. The creekline should be re-contoured so that the natural geomorphology of the watercourse is followed where possible (Waters and Rivers Commission 2002a). Designs for re-contouring of the creekline channel will be detailed in the subdivision stage and during development of the Urban Water Management Plan (UWMP).

Erosion of the creekline channel and bank can be attributed to high velocity water flows caused by changes in natural stream patterns. The velocity of surface water flows may need to be controlled in degraded areas to stabilise flows and reduce the transportation of sediments and nutrients downstream. The construction of pool-riffle sequences consists of improving channel stability through the addition of stabilised bed material such as rocks or large woody debris. Sediment accumulates behind the riffle and vegetation can be established on the flanks, stabilising the banks. By locking the sediment and reducing flow velocities, nutrients in the water column can be removed through biological processes or remain bound in the bed material. Water quality is also improved as the riffle creates turbulence that aerates the water, which in turn supports microbial activity that breaks down organic matter and assimilates nutrients (Waters and Rivers Commission 2001).

Permits are granted by the Department of Water to authorise interference or obstruction of the bed and banks of a watercourse or wetland. An application for a section 11/17/21A permit to interfere with bed and banks should be sought from the Department of water prior to river restoration works commencing.

The rehabilitation of the creekline to a living stream will maintain or improve the water quality of the creekline to relative pre-development conditions. Water quality of the main creekline is proposed to be improved through the construction of a bio-retention basin in the north east corner of Lot 105, adjacent to BusseII Highway. Basins provide water

360 envIronmental

quality treatment by removing fine sediment, trace metals, nutrients, bacteria and organics (Davis et al., 1998). Basins are designed to capture or either temporarily detain stormwater runoff before the water is released to the environment. The use of retention and infiltration systems and creation of surface water quality targets will be considered where possible at the UWMP stage.

• Revegetate banks and channels of watercourse;

O Re-contour areas of the creekline where the bank has been widened and deepened following natural geomorphology of watercourse where possible;

O Install bank protection measures where required;

O Install riffles along watercourse if appropriate, and in consultation with the project engineer; and

O Include addition of bioretention basins in final UWMP.

L a n d s c a p e Piar

Landscaping will be undertaken within three areas of the proposed development:

O 20 m Lot buffer:

O Road reserve; and

O 20 m wide landscape buffer (Figure 8).

Landscaping between the development and the highway is intended to provide a noise buffer and vegetation screen. Understorey vegetation within the road reserve will be removed and remaining trees will be pruned or removed so that groups of trees are no more than 5 m in width or singular trees have a height of no more than 3 m with a canopy of less than 5 m2 consistent with the Guidelines for Planning in Bushfire prone Areas (Department of Planning (DoP), Western Australian Planning Commission (WAPC) and Department of Fire and Emergency Services (FESA) 2015).

Planting will be undertaken in the 20 m Lot buffer to provide a vegetation screen and noise buffer. Native species chosen for planting in this area will grow to a height of no more than 1.5 m at full maturity and will be planted at a density of 1 plant per 2m2.

Remnant vegetation in the 20 m Lot buffer will be thinned so that all understorey is removed and remaining trees have a height of no more than 3 m with a canopy of less than 5 m2. Areas devoid of native vegetation will be mulched or landscaped as lawn.

Mulch will be applied to all landscaped areas at a depth of 75 millimetres (mm). Any imported composted mulch materials shall comply with AS 4454. The mulch (chipped vegetation materials) shall be free of fine or fibrous particles and suitable for placing on soil surfaces. All sourced mulch should be certified Dieback free sources.

0 Remove understorey;

O Remove trees so that aggregate tree groups are no more than 5 m in width measured perpendicular to the closest building;

O Prune existing trees to 2-3 m above ground level and a canopy of less than 5m2;

O Select plant species for use in landscaping with a height of no more than 1.5 m at full maturity; and

O Place mulch on ground to a depth of 75 millimetres.

The preliminary landscaping concept plan undertaken by Plan E Landscape Architecture, contains features including passive recreational POS areas, a gazebo, limestone retaining walls, seating, pedestrian bridge and a pathway system adjacent to the foreshore reserve through to natural bushland areas and the Railway Reserve trails.

The pathway system and proposed viewing areas will enable residents and visitors the opportunity to view and appreciate the foreshore environment. The implementation of the revegetation plan will provide a natural barrier to the movement of people beyond the proposed access path. The pathway will also form the boundary for weed control

measures. Access to the foreshore reserve will be limited to strategic areas and managed by providing designated paths that meander through the area. Access to the flood attenuation area should not be made available to the general public. The side slopes of the flood attenuation area are planned to be 1 in 6 (v:h) from the stormwater modelling undertaken by JDA Consultant Hydrologists (2012). It is envisaged that the plant species located along the margins of the foreshore and the flood attenuation area will be dense enough to discourage the public from entering these areas. Signs will be erected informing the public of potential water depths and not to enter the flood attenuation area or areas deemed unsafe along the foreshore reserve.

O Appropriate signs will be erected informing the public not to enter the flood attenuation area and in the revegetation areas.

3 . 1 1 E c i u u t i L l u r i L i no iwriaw, Interpretative signs should be used to inform residents and the general public of the on- going revegetation works and weed control to improve the riparian environment and enhance the habitat for native fauna species. There could also be information on large metal signs of local plant, mammal, reptile, amphibian or bird species. Safety signage should include a warning of any potential hazards including water safety and for child supervision.

360 environmental

Signage should be clearly visible but not detract from the aesthetic appeal of the viewing areas. Interpretative signs could consist of painted waist high posts with sturdy metal plaques. Public safety signs should be clearly visible and may need to be taller and of

more notable design.

Residents should be informed about the potential implications of their actions and encouraged to reduce possible impacts on the creekline. This could include minimising the use of fertilisers and pesticides on gardens, appropriate disposal of paints and chemicals, sensible use of detergents, waterwise gardening, discouraging dumping of garden waste and controlling pet cats and dogs movement within the areas. This could be done through leaflets or newsletters for new residents.

O Install interpretative signage informing the residents about the natural values of the creekline environment;

• Install safety signage informing residents and the public not to enter the water body, or pools, in the foreshore reserve including the flood attenuation area;

O The sign should include the slope gradient of the flood attenuation area and the potential depth; and

O Provide educational and interpretative information to the residents by means such as a leaflets or newsletters.

4 Monitoring It is important to monitor the progress of rehabilitation works over time to assess changes at the site and allow for contingency measures to be undertaken where required. Photo-points are sites where a series of photos are taken regularly, from the

same location at set intervals and using a standard method. Photopoints may be established to record changes in the landscape associated with revegetation works. 10x10 quadrats can also be used to assess native species survival rates and weed cover post weed control. The success of the revegetation and weed control works will be monitored using several permanent quadrats randomly spaced throughout the foreshore

reserve. The quadrats will record the presence/absence of native species and weed species, their percentage cover, height and health. The location of the quadrats will be marked using star pickets or by using existing features such as a large trees. Global Positioning System (GPS) coordinates will be taken at each quadrat to ensure that the

same locations are monitored each time. Monitoring of each quadrat will be undertaken quarterly over a two year period. Completion criteria have been developed to provide improved management through the monitoring period.

Completion criteria will be:

O A revegetation plant survival rate of at least 60%;

O Removal of Declared Weed Species Blackberry (*Rubus ulmifolius), Bridal Creeper (*Asparagus asparagoides) and Arum Lily (*Zantedeschia aethiopica);

O Reduce remaining weed populations to below 20% coverage within the sample quadrats;

Rehabilitation works, maintenance and monitoring within the foreshore reserve will be the responsibility of the developer for a two-year period (unless otherwise negotiated) until handover of management to the Body Corporate. After this time the weed control and revegetation program should be well established.

O The rehabilitation program will be monitored quarterly over a 2-year period to determine its performance. If the completion criteria (Section 4) are not met then contingency measures will be undertaken to improve required outcomes;

O The monitoring program will be conducted by an experienced botanist/ecologist.

A GRADE FORESHORE

A l :Pristine The river embankment and/or channel are entirely vegetated with native species and there is no evidence of human presence, or livestock damage.

A2:Near Native vegetation dominates but introduced weeds Pristine are

occasionally present in the understorey, though not the extent that they replace native vegetation. Otherwise there is no human impact.

A3:Slightly There are areas of localised human disturbance disturbed where the soil may be exposed and wed density is

relatively heavy, such as along walking or vehicle tracks. Otherwise, native plant dominate and would quickly regenerate in disturbed areas should human activity decline.

B GRADE FORESHORE

Bl:Degraded Weeds have become a significant component of the to Weed understorey vegetation. Although native species Infested remain dominant, a few have probably been replaced

or are being replaced by weeds. B2:Degraded In the understorey, weeds are about as abundant as to Heavily native Weed species. The regeneration of some tree and large Infested shrub species may have declined. B3:Degraded- Weeds dominant the understorey, but many native Weed species Dominated remain. Some tree and large shrub species may have

declined or disappeared.

C GRADE FORESHORE

C l : Erosion While trees remain, possibly some large shrubs or Prone grass tress, the understorey consists entirely of

weeds, mainly annual grasses. Most of the trees will be of only a few resilient of long-lived species and their regeneration will be mostly negligible. In this state, where the soil is supported by short-lived weeds, a small increase in physical disturbance will

expose the soil and render the river valley vulnerable to serious erosion.

02: Soil Here, the annual grasses and weeds have been Exposed removed through heavy livestock damage and

grazing, or as a result of recreational activities. Low level soil erosion has begun, by the action of either wind or water.

C3: Eroded Soil is being washed away from between tree roots, trees are being undermined and unsupported embankments are subsiding into the river valley.

D GRADE FORESHORE

Ditch- Fringing vegetation no longer acts to control erosion. Eroding Some trees and shrubs remain and act to retard

erosion in certain spots, but all are doomed to be undermined eventually.

D2: Ditch- No significant fringing vegetation remains, and Freely erosion is Eroding completely out of control. Undermined and subsided

embankments are common, as are large sediment plumes along the river channel.

D3: Drain- The highly eroded river valley has been fenced off Weed enabling Dominated colonisation by perennial weeds. The river has

become a simple drain, similar if not identical to the typical major urban drain.

*Holcus sp. (Yorkshore Fog)

*Homalanthus populifolius (Bleeding Heart)

1,2 Remove isolated plants before they set seed. Spray glyphosate 0.5% in spring or when the first seed head appears for optimal translocation to roots. Regular slashing reduces its vigour, but should not be done while plants are seeding. Severe defoliation and repeated herbicide treatment provide the best control. Controlled burning in spring or autumn can be a potential useful tool for suppression.

ETHOD OF MANAGEMENT AND C - (ELORAI3ASE 2 0 1 5

Hand remove small infestations and/or isolated plants, ensuring the taproot is removed. Alternatively wipe rosettes with glyphosate at 30%. For dense infestations, apply Lontrel® 10 ml / 10 L + wetting agent. Apply herbicide regularly to prevent seeding.

1,2 Prevent seed set. Hand pull or spray with

grass selective herbicide such as Fusiladee Forte in winter 4-6 weeks after opening rains. For larger plants up to flowering, increase rates of grass selective herbicide 3 to 4 fold. In agricultural areas, populations may be resistant to these herbicides and glyphosate

may be needed. Spray 10 m1/10 L glyphosate when plants are vegetative up to when seed heads are emerging. Late season applications of herbicide can reduce the numbers of seeds produced, viablity and seedling fitness.

WEED SPECIES

*Paspalum dilatatum (Paspalum)

DEGREE OF IN.

Scattered Scattered clumps 1 Cut out small populations and isolated plants,

ensure rhizome removal. Remove seed heads for safe disposal. At early head stage spray with glyphosate 10 ml/L. For established actively growing adult plants spray with Fusilade0 Forte 16 ml / L + wetting agent. Older stands can also be controlled with 1% glyphosate, preferably pre- or early flowering. Alternatively, cut near ground level and immediately wipe with 10% glyphosate. A repeat application may be required for well established plants. Follow-up control of seedlings with 2 ml/L Fusilade® Forte + wetting agent. Use hygiene practices - clean machinery and footwear after working in infested areas. Mowing and slashing will

remove flowering heads but will not control established plants and can spread seed.

*Physalis angulata (Cape Gooseberries)

regrowth at 0.5 m with metsulfuron methyl 1 g/10 L in summer to autumn. May be harder to kill than R. anglocandicans as the latter is considered to have the more vigorous growth habit of the two species. Will require follow up for a number of years.

*Solanum nigrum (Blackberry nightshade)

*Tropaeolum majus (Nasturtium)

A few scattered 1 Prevent seed set for several years. Hand weed plants small infestations. In bushland situations,

manually remove plants before flowering. For large infestations, 1 L/ha Starane® (20 m1/10 L) applied when actively growing in summer, will provide reasonably selective control. Do not use in or near wetlands. Control infestations within 5 km of the target area to reduce dispersal of seed by birds. 1 L/ha 2,4-D amine (500 g/L) or 20 m1/10 L can also be used for control of young plants in early

s tim mer. A few scattered 1 Pull up all vegetation and dispose of it. plants Spray: glyphosate 10m1/L water in spring to

Approximately 10 1 Spot spray metsulfuron methyl or chlorsulfuron plants in the creekbed 0.4 g/15 L of water + Pulse® or 5g /ha + in the eastern end of Pulse®. Herbicide application can send some Zone 1 tubers into dormancy therefore any control

program needs to continue for five years. Apply any time between June and September. Early management prevents flowering and seed set but may miss later sprouting tubers.
