1 Introduction

1.1 Background

Peet Forrestdale Syndicate (the ‘Proponent’) is continuing the ‘Hilbert Park Estate’ residential development, located on Lot 9001 Rowley road, Hilbert Park (referred to herein as ‘the site’). The site is located within the City of Armadale approximately 27 km southeast of the Perth. The site covers 74.47 ha and forms part of Precinct 21 (formally Precinct K) of the Wungong Urban Water (WUW) Master Plan area administered by Development WA (formerly the Metropolitan Redevelopment Authority (MRA) and the Armadale Redevelopment Authority). The Wungong River runs adjacent to the north eastern boundary, and flows in a north-western direction. The location of Precinct 21, the site boundary, and the Wungong River are shown in Figure 1.

The Local Structure Plan (LSP) for Precinct 21 (then Precinct K) (which includes the site) is provided in Appendix A and was previously approved in 2009.

The proponent is progressing with a LSP amendment over the site which will allow for the creation of 1,028 residential lots (including Stages 1-2 already constructed), a (4 ha) primary school, public open space (POS) (including Park Avenues), community parks, a neighbourhood activity centre and a foreshore that will be integrated with the Wungong River and associated reserve. The proposed LSP is provided in Appendix B.

1.2 Town planning context

The site is situated within the boundary of the Wungong Urban Water Redevelopment Scheme 2007 (WUW Scheme), and as a result the City’s Town Planning Scheme (TPS) No. 4 and the Metropolitan Region Scheme (MRS) are not applicable to the site. The WUW Master Plan, acts as a district-scale structure plan to allow for the implementation of the WUW Scheme (ARA 2013).

In accordance with the endorsed WUW Master Plan, the site is proposed for urban development. The majority of the site is zoned “Suburban Development”, with a portion also zoned “Urban Development” under the WUW Scheme. Additionally, the site contains areas zoned “Active Open Space” and “Neighbourhood Activity Centre”. The LSP proposed for the site has been prepared to generally align with the land uses set out in the WUW Master Plan.

1.3 Policy framework

The following Federal and State legal frameworks and policies are relevant to the site:

• Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) • Environmental Protection Act 1986 (EP Act) • Wildlife Conservation Act 1950 (WC Act) • Aboriginal Heritage Act 1972 (AHA) • State Planning Policy No. 2.9 Water Resources (SPP 2.9) (WAPC 2006a) • State Planning Policy No. 3.4 Natural Hazards and Disasters (SPP 3.4) (WAPC 2014)

Project number: EP17-097(13)|March 2021 Page 1 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

• State Planning Policy No. 3.7 Planning for Bushfire Management (SPP 3.7) (WAPC and DFES 2017) • Water Quality Improvement Plan for the Rivers and Estuary of the Peel-Harvey System (EPA 2008) • Wetlands Conservation Policy for Western Australia (Government of Western Australia 1997) • Environmental Protection Authority Position Statement No. 4 Environmental Protection of Wetlands (EPA 2004b) • Environmental Protection Authority Guidance Statement No. 33 Environmental Guidance for Planning and Development (EPA 2008) • Armadale Redevelopment Scheme 2 (Development WA 2020) • Waterwise Perth 2 Year Action Plan (Government of WA 2020).

In addition to the above policies, there are a number of published guidelines and standards available that are relevant to the site, and include:

• Wungong Urban Water Master Plan (WUWMP) (MRA 2009) • Public Open Space Policy (MRA 2013) • Wungong Urban Water (WUW) Redevelopment Scheme 2007 (ARA 2013) • Development Policies (MRA 2017a) • WUW Project Area Design Guidelines (MRA 2017b) • Report for Wungong Urban Water Project – Operational Water Quality Objectives (OWQO) (GHD 2011) • WUW Guideline for Water Monitoring (MRA 2015) • Subdivision and Development Guidelines (CoA 2014) • Stormwater Management Handbook (CoA 2015) • Landscape Guidelines for Public Open Space (CoA 2013).

1.4 Purpose of this report

As required under the Ministerial Statement 762, namely Condition 7-1, and Section 6.8(l) of the WUW Scheme, a landscape and irrigation management strategy (LIMS) is required to be prepared prior to the approval of a structure plan.

A LIMS was previously prepared by Cardno (2009) to support the previous LSP. The previous LIMS was approved in 2009 and is provided in Appendix C. The LSP has since undergone minor design changes, and hence the proponent is progressing with a LSP amendment over the site. The LIMS therefore requires updating to reflect these changes and to ensure that the previously proposed strategy is still applicable to the latest iteration of LSP. This LIMS addendum should therefore be read in conjunction with the previously approved LIMS.

A comparison between the previously approved LSP and the proposed LSP is further discussed in Section 2.

1.5 Objectives of LIMS

The objectives of the LIMS are consistent with the previous LIMS (see Section 1.3 in the report provided in Appendix C).

Project number: EP17-097(13)|March 2021 Page 2 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

2 Proposed Structure Plan

The structure plan amendment covers Lot 9001 Hilbert Road, and is provided in Appendix B. The LSP proposes the following land uses:

• Neighbourhood activity centre (including community centre) • Urban (250 m2) and suburban (380 m2) residential lots • Primary School (4 ha) • Part high school (portion of the oval) • Three community Parks (0.50 ha to 1.07 ha) • Community site (0.25 ha) • Park Avenues (0.55 ha – 2.04 ha) • Foreshore buffer (30 m wide) • Road network.

The previously approved LSP covered the entire of Precinct 21 and is provided in Appendix A. The proposed updates are relevant to only a portion of Precinct 21 (i.e. the site). In summary the LSP has undergone the following minor design changes:

• Minor realigning of the road network (including the main north-south road). • Park Avenues have been re-aligned to connect (and in turn discharge surface water) into the Wungong River. • Community parks have been co-located to surround the Park Avenues. • The eastern primary school has been slightly re-aligned to allow more interaction with the northern and southern Park Avenues.

3 Existing Environment

This LIMS has been informed by various recent management strategies and investigations, namely:

• District Water Management Strategy (DWMS) (JDA Hydrologists 2009) • Precinct K LWMS (Emerson Stewart 2009a) • Peet Forrestdale Stage 3 UWMP (Emerge Associates 2018) • Peet Forrestdale Stage 1 & 2 UWMP (JDA 2015) • Foreshore Management Plan (ENV 2011) • Flora and Vegetation Assessment, Brookdale Redevelopment Area (ATA Environmental 2006) • Precinct K Flora and Vegetation Assessment and Tree Survey (Cardno 2008) • Lot 1 Hilbert Road, Brookdale tree inspection (Arbor Logic 2007) • Wungong Flood Modelling and Drainage Study - Technical Report (DHI 2020).

3.1 Climate

The site experiences a dry Mediterranean climate of hot dry summers and cool wet winters. Long term climatic averages indicate that the site is located in an area of moderate rainfall, receiving 804 mm on average annually with the majority of rainfall received between May and August (BoM 2021).

3.2 Topography

The topography within the site is relatively flat with elevations generally ranging from 27 metres Australian height datum (m AHD) down to 25 m AHD (DWER 2021b). A localised low point of 24 m AHD is located towards the north-eastern boundary, along the Wungong River. The Wungong River adjacent to the site has inverts of approximately 24 m AHD at the northern end of the site to approximately 25 m AHD at the southern end of the site. The topographic contours for the site and surrounding areas are shown in Figure 2.

3.3 Geotechnical conditions

3.3.1 Regional geology

The majority of the site is characterised as Bassendean Sand or Guildford Formation and is described as sand (S8 and S10) or sandy clay (Cs) (Gozzard 1986). Soils near the Wungong River are described as clayey sandy silt (Msc1). Regional geology is presented in Figure 3.

3.3.2 Local geology and soil

A geotechnical investigation was conducted within Precinct 21 and surrounding precincts between 2007 to 2008 (PB 2008). Within Precinct 21, 43 test pits were excavated (TP01-TP43) up to 3 m below ground level (BGL). Test pit locations are shown in Figure 3. In summary, the geotechnical investigation (PB 2008) reported the soil profile beneath the site as follows:

• Topsoil throughout the entire site is a thin layer (average of 100 mm) of silty sand containing organic fines.

Project number: EP17-097(13)|March 2021 Page 4 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

• Underlain by a layer of silty sand - fine to medium grained, brown, non-plastic, cemented, up to 0.5 m BGL. • Underlain by a layer of clayey sand starting at 0.5 m BGL - medium to fine grained, with fines of low to medium plasticity encountered in majority of the test pits. • High plasticity clayey sand/sandy silt was encountered at TP17, TP22 and TP34, starting at 0.4, 1.8 and 2.3 m BGL, respectively.

No permeability testing was undertaken within the site, although the geotechnical investigation indicates that infiltration rates are expected to range between 0 m/day (sandy clays) and 30 m/day (sand and gravelly sand) (PB 2008).

3.3.3 Acid sulfate soils

There is a moderate to low risk of acid sulfate soils (ASS) occurring within 3 m of the natural surface across the site (DWER 2020a), as shown in Figure 4.

During geotechnical investigations by PB (2008), field pH testing was conducted on two test pits within the site, which were then sent for laboratory analysis. TP27 encountered potential ASS during field investigations at 0.5 and 2.5 m BGL, although laboratory testing results showed no ASS encountered. Laboratory analysis of TP35 found ASS soils from 0, 0.5, 1.0, 2.0 and 2.5 m BGL.

The locations of TP27 and TP35 are shown in Figure 4.

3.4 Surface water

3.4.1 Wetlands

The entire site is classified as a multiple use wetland (MUW) (UFI: 15797), associated with the Armadale palusplain (DBCA 2020). Located outside of the site and directly towards the east is a resource enhancement wetland (REW) (UFI: 15438) and a conservation category wetland (CCW) (UFI: 14475).

The location of these wetlands is shown in Figure 5.

3.4.2 Existing hydrological features

The Wungong River is an ephemeral watercourse which flows in a north-westerly direction along the eastern boundary of Precinct 21, as shown in Figure 6. The Wungong River becomes the Southern River at Passmore Street, Gosnells (Emerson Stewart 2009) and is a major tributary to the Canning River (part of the Swan-Canning River System). The eastern boundary is located adjacent to the Wungong River floodplain area (floodway and flood fringe), and the majority of the site is within the 1% annual exceedance probability (AEP) floodplain development control area (i.e. 300 m buffer around the floodplain area) as shown in Figure 6.

The Wungong River flows are regulated by the Water Corporation via Wungong Dam which is located approximately 4.5 km upstream of its crossing with South Western Highway (DHI 2020). In terms of surface flows, the site therefore represents a highly modified environment that is controlled by release flows from the Wungong Dam (DHI 2020).

Project number: EP17-097(13)|March 2021 Page 5 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

There are no other formal surface runoff channels across the site though runoff could potentially occur following significant or long-duration rainfall events due to the low permeable soils, which is consistent with a palusplain wetland. Surface runoff would be seen as shallow sheet flow and localised ponding due to the gentle topography, rather than any defined drainage pathway.

3.5 Flora

3.5.1 Vegetation communities

An ecologist from Emerge Associates attended site on 15 February 2021 and confirmed that the majority of the site supports non-native and planted vegetation, primarily dominated by non-native pasture grasses with planted Eucalyptus camaldulensis located within the southern portion of the site. Large stands of *Colocasia esculenta were present within the Wungong River.

A single native plant community, ErMr, was present within the northern portion of the site. This plant community consisted of Eucalyptus rudis and Melaleuca rhaphiophylla over non-native grasses.

The location of this community is shown in Figure 7.

3.5.2 Vegetation condition

Vegetation condition within the site was assessed by Emerge Associates using methods from Keighery (1994). The ErMr plant community was determined to be in ‘Degraded’ condition as it lacks native understorey species, whilst the remainder of the site is identified as being in ‘Completely Degraded’ condition.

The extent of vegetation by condition is shown in Figure 7.

3.6 Ecological linkages

A biodiversity linkage (No. 56) occurs along the north eastern boundary of the site and along the Wungong River to the north and south. An additional biodiversity linkage is located along the south west corner of the site (No. 61).

The location of these linkages (which are generally outside the site) is shown in Figure 7.

3.7 Fauna

An ecologist from Emerge Associates attended site in February 2021, and it was concluded that fauna habitat values within the site have been compromised by historical vegetation clearing and grazing. The areas of riparian vegetation along Wungong River represent the highest value fauna habitat when compared to the widespread areas of parkland cleared vegetation.

In consideration of the observed site characteristics, the overall diversity of native fauna in the site is expected to be well below pre-disturbance levels. Due to historical clearing and degradation of native vegetation, the majority of the site has limited natural values, and it is likely to be only utilised by generally common and widespread fauna species with non-specific requirements.

3.7.1.1 Species of conservation significance

Based upon a site walkover, it is considered that three species of conservation significance may use the site for some purpose, including:

• Calyptorhynchus latirostris (Carnaby’s cockatoo) Areas of non-native and planted vegetation represent foraging habitat for the species. Where larger endemic trees (DBH > 500 mm) occur within the site, these trees represent potential breeding habitat based on the EPBC Act referral guidelines for the species (DSEWPaC 2012). • Calyptorhynchus banksii naso (forest red-tailed black cockatoo) Areas of non-native and planted vegetation represent foraging habitat for the species. Where larger endemic trees (DBH > 500 mm) occur within the site, these trees represent potential breeding habitat based on the EPBC Act referral guidelines for the species (DSEWPaC 2012). • Calyptorhynchus baudinii (Baudin’s cockatoo) Where larger endemic trees (DBH > 500 mm) occur within the site, these trees represent potential breeding habitat based on the EPBC Act referral guidelines for the species (DSEWPaC 2012)..

The site supports limited black cockatoo roosting habitat in the form of large native and non-native trees. No evidence of roosting activity such as droppings, feathers or branch clippings were observed during the site visit.

3.8 Groundwater

3.8.1 Regional groundwater

The Water Register (DWER 2020c) indicates that aquifers beneath the site are the Superficial Swan (unconfined) and the Leederville aquifer (confined) (DWER 2020a). The Perth Groundwater Map (DWER 2020a) indicates that maximum groundwater beneath the site flows in a north-westerly direction, between 25 m to 27.5 m AHD (i.e. 0 to 1 m BGL) (DWER 2020a), as shown in Figure 2.

3.8.2 Local groundwater

The WIR database (DWER 2020d) indicates that two DWER bores (Ref: 61410154, 61410155) are located south of Precinct 21 (see Figure 2) and have monthly groundwater level data available. Bore 61410155 has insufficient information to characterise its nature and therefore its measured levels were not used for the purposes of this report. The data from bore 61410154 provides data which is considered to represent the recent and relevant groundwater levels beneath the site. Measured levels within bore 61410154 between 2010 – 2020 showed the maximum groundwater level (MGL) to occur in 2018 at 24.04 mAHD, or 3.43 mBGL.

JDA undertook regular groundwater monitoring from 2015 to 2017 at eight locations within the site as shown in Figure 2. Emerge Associates then continued groundwater monitoring from 2018 to 2019 at these existing bores. Bores MB06 and HB01 were historically monitored sporadically between 2014-2017 by JDA, however the bores were not monitored post 2017 and the results are deemed unreliable.

Project number: EP17-097(13)|March 2021 Page 7 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

Based on the depth of installation (approximately 6-7 m), measured MGLs from three bores (C50d, MB04, and MB05) are inferred to be associated with a low permeability layer, therefore are considered to represent perched groundwater, which is consistent with the findings in the geotechnical report and the regional geology. Results from these bores found that the seasonal perched groundwater is close to the surface, and is between 25.37 to 26.62 mAHD (i.e. 0.10 mBGL – 1.3 mBGL). Consequently, seasonal peak water levels close to the existing ground surface are likely due to localised low permeability soil conditions, and are not influenced by the regional/permanent aquifers.

The remaining bores are installed to greater depths (>14m) and are inferred to be a representative of the Superficial Swan aquifer. The maximum recorded level from these bores was found to also occur in 2018 (concurrent with the DWER bore 61410154), and ranged from 22.27 mAHD to 23.97 mAHD (i.e. 1.5 mBGL to 4 mBGL).

The MGL contours from the bores which were found to be a representation of the superficial aquifer are shown in Figure 2.

3.8.3 Groundwater quality

During groundwater monitoring Emerge Associates undertook quarterly water quality sampling in 2018 and bi-annual water quality sampling in 2019. Groundwater quality results are shown in Table 1.

While there is no nationally recognised guideline for groundwater quality, in order to provide some context the monitoring results were compared to the National Water Quality Management Strategy (NWQMS) guidelines (ANZECC and ARMCANZ 2018). This comparison indicates relatively acidic conditions with elevated reactive phosphorous, TN and TP concentrations mainly within bores; HPEB4, MB04 and MB05. Nutrients within these bores fluctuated throughout 2018 to 2019; e.g. bore HPEB4 recorded significantly elevated TN levels in March 2018 at 55.6 mg/L however recorded levels of 2.7 and 3.5 mg/L in December 2018 and July 2019, respectively. Similarly, bore MB05 recorded TN levels between 4-20 mg/L in 2018, whereas TN levels in 2019 were recorded between 46-50 mg/L. TP was elevated in the majority of samples during both 2018 and 2019 monitoring rounds, although recorded high levels in July and October 2019 at 7.6 and 8.7 mg/L, respectively.

Elevated nutrient concentrations, especially organic forms of nitrogen, are typical of agricultural areas due to the presence of livestock and use of fertilisers. This is consistent with the existing land use across the site.

3.9 Heritage

3.9.1 Indigenous heritage

In accordance with the Aboriginal Heritage Due Diligence Guidelines (DAA 2013), a search of the AHIS online database (DPLH 2020) was undertaken. Two heritage sites are located within the site being:

• Wungong Brook (Site 3512), a registered mythological site • Brookdale Archaeological Site 015 (Site 26094), a registered ‘artefacts/scatter, archaeological deposit’ site.

A detailed archaeological and ethnographic survey was conducted over the WUW Master Plan area in 2006 by Tempus Archaeology. This survey found a number of new archaeological sites, including Brookdale Archaeological Site 015.

The location of the registered Aboriginal sites within the site is shown in Figure 8.

Project number: EP17-097(13)|March 2021 Page 9 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

4 Landscape Master Plan

The areas of open space within the proposed LSP include the following:

• Community Parks • Park Avenues • Wungong foreshore area • Primary and High school open space

4.1 Community Parks

Community Parks will be located within the site which will be designed to fulfil the associated neighbourhood function and amenity. The parks will have a minimum of 60 m x 60 m of which is unencumbered by small rainfall event runoff (i.e. the first 15 mm). The parks however will incorporate drainage for major storm event runoff (1% Annual Exceedance Probability (AEP)) within flood storage areas (FSAs). The locations of Community Parks are shown in Appendix B.

Each Community Park will vary in facilities, such as shade structures, picnic facilities, playground equipment, large open turfed areas, fitness equipment, barbeques and seating so as to suit the local site conditions and requirements of the adjoining neighbourhood.

Two parks will be located adjacent to the living stream on its eastern side. These parks will be used for passive recreation and will include native planting some turf. There will be a provision of furniture, shelter and a dual use path (DUP) which will connect the park with the adjacent living stream/Park Avenue. The Community Park within the centre of the site will also focus on the retention and enhancement of the existing Aboriginal heritage site (DIA 26094). There will be a provision of interpretive signage and educational material to inform people of the Aboriginal heritage values associated with this location.

A third Community Park is located along the north-eastern boundary and will interact with the foreshore reserve. This park will include native planting with some turf area dedicated to passive recreation. A fourth park is also located on Hilbert Road and will interact with the adjacent landholdings (future stages of Hilbert Park).

4.2 Park Avenues

The two central Park Avenues (refer to Appendix B for locations) will have conveyance channels designed to convey runoff into the Wungong River. The conveyance channels will be designed based on the following living stream principles:

• A frequent flow channel (V-shaped) for small rainfall events and baseflow. This will be a 0.3 m deep channel with 1:3 side slopes. • A bankfull width that is determined by the area available following accommodation of suitable side slopes (1:6), the required flood depth and the width of the Park Avenue. This varies from 4.5 m to 8 m wide. • A broader (trapezoidal) channel that will convey events up to the 1% AEP event

Project number: EP17-097(13)|March 2021 Page 10 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

• The frequent flow channel will include meanders, pools and riffles within the base of the bankfull width which mimic a natural system. • The frequent flow channel will be stabilised with native plant species that are able to withstand episodic inundation and will assist in removing pollutants, and other appropriate surface treatments (e.g. cracked gravel) that will resist erosion. • The base of the living stream frequent flow channel within the Park Avenues will be underlain with an appropriate soil media to increase nutrient removal from runoff during conveyance, and that will also allow infiltration.

Living stream features will provide not only a drainage function but also a variety of ecological zones and restoration opportunities. These will include open woodland and parkland, revegetated riparian systems, shelters and boardwalks and an integrated path and walk trail network that links with the wider path system. The living stream features will include a DUP on both sides of the living stream and/or a walking trail.

Planting will consist of native and endemic species, as outlined in Appendix D with a variety of tree, shrub, groundcover, reed and sedge species. A typical cross section of the Living Stream is also provided in Appendix D and shows mostly revegetated areas and a passive recreational node.

4.3 Wungong Foreshore Area

The Wungong Foreshore area will be designed and managed as described in the original LIMS, including the philosophy to revegetate with native flora and to provide DUPs and associated passive amenity. Areas for passive recreation will be separated from rehabilitated areas with fencing.

Rainfall events greater than the small event (i.e. greater first 15 mm) will overflow from treatment structures (i.e. living streams, BRAs) to the foreshore reserve. As the Wungong River is not located within the site, no changes to the channel structure will be made.

Appendix D shows a typical cross section of the reserve, including dedicated revegetation to the riparian zone, as well as the planting pallet.

4.4 Primary and High school open space

Formal active recreation facilities will be associated with the primary and high schools (the site includes a portion of the high schools open space area). These open space areas will allow for the shared use of active recreation facilities with both the wider community and the schools. Typically, the schools will include a football and cricket oval, full sized mixed use sports court, cricket nets, high quality landscaping, turf and shade trees.

Project number: EP17-097(13)|March 2021 Page 11 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

5 Planning and Design

The following section summarises the minor amendments to the LIMS in accordance with the new LSP. All other principals and management practices proposed in the LIMS are consistent with the current intentions of the proposed LSP.

5.1 Vegetation retention

Recent flora investigations conducted across the site (see Section 3.5) identified that majority of vegetation across the site is in a degraded condition associated with past land uses. Additionally, due to the existing clay layer and perched groundwater system (see Section 3.3 and Section 3.8) fill will be required to ensure sufficient clearance to the design levels, which limits the possibility for tree retention within POS and drainage areas.

Vegetation around the foreshore buffer and within the aboriginal heritage site will be the key flora retention area within the site, however some alterations to the Wungong River banks will be required to give it a more natural form, and during this process some trees may be lost within the riparian zone. This will be further investigated during detailed design however is expected to involve retention where possible and re-vegetation.

Detailed landscape plans will be submitted during subdivision, and these plans will clearly identify vegetation which will be retained.

5.2 Proposed landscape planting

Landscape planting across the site will focus on native waterwise species, with some exotics and shade trees where necessary, as was proposed in Section 3.2.4 of the previous LIMS (see Appendix C). The planting pallet for the site, including the POS areas, water sensitive urban design (WSUD) features, and the foreshore area has undergone minor amendment, and is presented in the landscape Master Plan provided in Appendix D.

5.3 Drainage strategy

The drainage strategy for the site will incorporate various WSUD features and will revolve around the two central Park Avenues (shown in Appendix B) which will be designed using living stream principles.

The stormwater management strategy for the site is to retain and treat surface flows where possible, and detain remaining flows before discharging into the Wungong River. Runoff will be managed via various WSUD assets, including:

• Median & roadside swales within road reserves and open spaces • Living streams located within Park Avenues • Bio-retention areas (BRAs) located within public open spaces • Flood storage basins (FSAs) collocated with Community Parks • Waterwise landscaping.

Project number: EP17-097(13)|March 2021 Page 12 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

5.4 Irrigation strategy

5.4.1 Groundwater

Groundwater will be utilised for irrigation of the site, and the proponent has secured the following allocations:

• GWL169161 – 30,000 kL/ha/year for irrigation of up to 4 ha of POS. • GWL171022 – 76,850 kL/ha/year for dust suppression and earthworks purposes.

The location of groundwater abstraction bores for irrigation purposes is still to be determined pending confirmation of appropriate water quality and aquifer yield capabilities within proposed bores.

5.4.1.1 Irrigation

As noted in the landscape plan provided in Appendix D, the LSP provides 28,688 m2 of turf (within POS/community parks), which at a rate of 7,500 kL/ha/year will require 21,516 kL/annum of permanent irrigation. This will be supplied utilising the proponents existing groundwater licence of 30,000 kL/annum. Additional landscaped areas will be irrigated via the remaining groundwater allocation (i.e. 8,484 kL), via a temporary establishment licence, or via temporary hand watering.

5.4.2 Alternative water sources

An alternative non-drinking water supply was identified in the LWMS (Emerson Stewart 2009b) utilising third pipe infrastructure, and it is understood that the City are continuing to investigate alternative non-potable water sources. Designs for such a supply have not been progressed to date and the use of a regional non-potable water supply is likely to be most relevant to regional open space infrastructure in other precincts and it is therefore not considered as a potential supply for the site.

5.5 Waterwise gardens

Reductions in water use for irrigation by employing water efficiency measures can significantly reduce water usage. The following water efficiency measures will be used:

• Where required, soil shall be improved with soil conditioner certified to Australian Standard AS4454 to a minimum depth of 150 mm where turf is to be planted and a minimum depth of 300 mm for garden beds. • Garden beds to be mulched to 75 mm with a product certified to Australian Standard AS4454. • Implementation of hydrozoning design practices, which will group plant species with similar / same irrigation requirements. • Irrigation systems will have emitters which disperse droplets to minimise losses to evaporation. • Irrigation will not be utilised during winter months. • The adoption of xeriscaped gardens (garden beds are landscaped using ‘waterwise plants’) where possible. • Community awareness of water conservation will be promoted at the point of sale and during the development sales lifespan.

Project number: EP17-097(13)|March 2021 Page 13 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

Waterwise gardening (WWG) principles will be utilised within all open space areas (i.e. community parks, Park Avenues and the foreshore reserve) and WSUD assets (Swales, living streams, BRAs, FSAs) to encourage biological nutrient uptake, consistent with the Vegetation guidelines for stormwater biofilters in the south-west of Western Australia (Monash University 2014). Uptake of WWG practices for lot landscaping will be encouraged by the proponent at point of sale of lots through provision of educational material.

5.6 Nutrient management

The development of the site is anticipated to result in a reduction of nutrient levels consistent with the change in land use from agricultural to urban. The use of WSUD treatment infrastructure (detailed in Section 5.3) within the drainage network will further reduce the mobilisation of urban sourced nutrients.

5.7 Aboriginal heritage

The protection and enhancement strategy for the aboriginal heritage site (see Section 3.9) is still applicable to what is proposed in Section 3.2.12 of the previous LIMS (see Appendix C).

5.8 Ecological Corridors

The enhancement strategy for ecological corridors is still applicable to what is proposed in Section 3.2.13 of the previous LIMS (see Appendix C).

Project number: EP17-097(13)|March 2021 Page 14 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

6 Implementation of the Management Strategy

The management elements set out in this LIMS outlines the principles and practices required to achieve the vision of the Hilbert Park development and to satisfy federal, State and local Government statutory requirements. The management elements detailed within the LIMS and that are relevant to the site include:

• Construction management • Vegetation retention • Disease management • Weed management • Planting within open space areas • Bushfire management • Irrigation strategy • Aboriginal heritage management • Public furniture and art.

The key management actions applicable to the site are the ‘Key Management Actions and Responsibilities’ table provided in Appendix E. The table provides an overview of the management practices to be implemented during and post-construction and serves to guide the more detailed management and operational processes implemented at subdivision.

The key management actions detailed within Appendix E have been adopted from, and are consistent with, the relevant management strategies required under the Ministerial Statement 762 (as detailed within Section 1.3).

It should be noted that for areas where revegetation is undertaken, the full list of maintenance elements listed in Table 2 may not apply. As part of revegetation works, a plant survival rate of at least 75% is required to be achieved and the following actions completed where required:

• Vegetation monitoring • Ongoing weed management • Removal of tree guards • Stock or other protective fencing • Infill planting • Thinning • Ongoing pruning, irrigation, fertiliser application (if appropriate) and mulching.

In addition to the above, fire breaks are required to be checked annually with all potential fire fuel material removed in October. The criteria for fire management are established by the requirements of the City and the Bush Fires Act 1954. These criteria will be required to be presented in detail in a Fire Management Plan to support subdivision applications for developments adjacent to the Foreshore Reserve. The Fire Management Plan will include, as the primary contingency, for any vegetation encroaching within the firebreak to be removed.

7.1 Contract (developer) maintenance

The contract maintenance refers to the period in which the developer will maintain the open space areas following practical completion of works.

Practical completion relates to when landscaping construction works have been completed in accordance with the detailed landscape plans, to be submitted prior to the construction of the POS areas.

Following practical completion the developer will organise to:

• Carry out any remedial work noted during the practical completion inspection without delay • Undertake maintenance of the public open space areas as agreed with the City and MRA.

The developer will be required to maintain the POS areas for a minimum period of two years, following practical completion. During this period of maintenance, the developer must achieve a plant survival rate of at least 75%.

7.2 Scheduled handover

After the two year contract maintenance period the POS areas will be handed over to the City to control, fund and manage unless otherwise agreed. This may be considered appropriate by the developer due to the proximity of work in adjacent stages of subdivision and the need to manage any potential impacts, and/or in some instances it may be more practical for the developer to maintain these areas for a period longer than two years.

Project number: EP17-097(13)|March 2021 Page 18 Prepared for Peet Forrestdale Land Syndicate Ltd Doc No.: EP17-097(13)—025A| Version: 1 Landscape and Irrigation Management Strategy Addendum Lot 9001 Rowley Road, Hilbert Park

Prior to handover, the City will conduct a handover inspection. Following handover inspection and prior to the handover date, the developer shall:

• Rectify all major defects noted (not associated with standard wear and tear) during the handover inspection and others that may become evident prior to the handover date • Seek written confirmation that the City accepts responsibility for maintenance and liability for the location requested.

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

1. INTRODUCTION

1.1 Background

The locality of Brookdale is situated in the South East Corridor of Perth approximately 25 km from Perth, within the municipality of the City of Armadale. Brookdale is a constituent area of the Armadale Redevelopment Scheme and therefore falls under the planning jurisdiction of the Armadale Redevelopment Authority (ARA). The majority of Precinct K has a “Suburban” zoning classification under the Wungong Urban Water (WUW) Master Plan, (referred to within this report as “the Master Plan”). Portions of Precinct K are also zoned “Urban”, “Neighbourhood Activity Centre” and “Active Open Space”. The Master Plan links land use planning and urban water management across the Wungong Urban Water region (ARA, 2006). The locality of the study area is shown in Figure 1.

Identified as one of eight strategic regional centres under the Metropolitan Centres Policy Statement for the Perth Metropolitan Region (1991 and 2000), it was considered that Armadale as a regional centre was yet to share in the crucial public and private sector investment that had and is being enjoyed by many other areas in the metropolitan area (ARA 2004).

In early 2001 the State Government announced among its pre-election commitments the establishment of the ARA and, after assuming government, established the ARA. The purpose of the ARA is to establish a physical, social and environmental framework enabling the City to build on its existing strengths and assets, and develop the multi-dimensional place of civic, cultural and economic significance that a strategic regional centre should be. In establishing the City’s place in the metropolitan hierarchy, the redevelopment of Armadale is designed to draw upon and accentuate the points of difference that give Armadale its unique character (ARA 2004).

The WUW Redevelopment Scheme 2006 was referred to the Environmental Protection Act, and it was considered by the Environmental Protection Authority (EPA) that the proposed land use change had the potential to have a significant impact on the environment. Accordingly the level of assessment was set at “Assessed: Environmental Review Required” (EPA Assessment No. 1647).

An Environmental Review was prepared by ATA Environmental (2006) on behalf of the ARA to meet the requirements of the assessment process. Following the EPA’s assessment, Bulletin 1253 was released outlining the EPA’s advice to the Minister for the Environment on the environmental factors and recommended conditions relevant to the proposed scheme. A subsequent Ministerial Statement was then issued by the Minister for the Environment outlining the conditions (Ministerial Statement 762, 2008) to be applied in the scheme text.

The Master Plan was prepared by ARA to provide a framework for future development across the Master Plan area and provided a framework for local structure planning to

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

proceed in various precincts. A Local Structure Plan (LSP) has been prepared by Peet Limited (Peet) for the Precinct K area to meet the planning requirements outlined in the Master Plan and give a more detailed view of how development would proceed across the precinct. The LSP is supported by a number of technical documents, one of which is the Landscape and Irrigation Management Strategy (LIMS).

1.2 Purpose of Landscape and Irrigation Management Strategy

It is specified as a condition of the Ministerial Statement that a LIMS needs to be prepared prior to the approval of a structure plan. The wording of the condition is as follows: “A Landscape and Irrigation Management Strategy for the structure plan area shall be prepared by the developer and shall be advertised for public comment and the LIMS shall be finalised to the requirements of the Armadale Redevelopment Authority on advice of the Department of Environment and Conservation, the Department of Water, the City of Armadale and the Department for Planning and Infrastructure (Strategic Biodiversity Planning) as appropriate” (Ministerial Statement 762).

The ARA has developed an overall framework for the WUW Redevelopment area. A number of policies and guiding documents have been prepared to aid in the preparation of specific documents. The Revised Draft Integrated Open Landscape and Irrigation policy (ARA 2008) outlines specific requirements that are addressed in this LIMS.

This LIMS has been prepared to fulfill the condition outlined in the Ministerial Statement and in accordance with the Revised Draft Integrated Open Landscape and Irrigation policy (ARA 2008).

1.3 Objectives of LIMS

As outlined above, a key component of the WUW Master Plan is the successful preparation and implementation of a LIMS that outlines strategies for optimising efficiency and long term effectiveness for landscaping and irrigation. This LIMS was developed with a key consideration being the need to manage nutrient losses to the Southern River catchment.

As outlined in Ministerial Statement 762, the objective of the LIMS is to guide rehabilitation and management of remnant vegetation, fauna habitat and ecological linkages, new landscape planting and water sensitive urban design features within development and areas of open space.

Based on Ministerial Statement 762, the LIMS should include but not be limited to: • As appropriate, flora and vegetation studies to complement those reported in Flora and Vegetation Assessment Brookdale Redevelopment Area and guidance on more detailed work at subsequent stages of planning; • Rehabilitation and revegetation strategy employing native local provenance; • Enhancement of ecological corridors; • Fire management

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

• Mitigation strategies, including, in the case of unavoidable clearing of vegetation from key habitats, an offsets plan to the requirements of the Armadale Redevelopment Authority to include the planting and revegetation of POS areas; • Monitoring criteria to determine the success of rehabilitation and revegetation and an evaluation program; • Progress and compliance reporting; and • Timing, implementation and review schedules.

This LIMS has also been developed to meet the objectives of the Revised Draft Integrated Open Space and Landscape Policy which are as follows: • To facilitate the realisation of the Master Plan riverine, wetland and cultural landscape elements and their associated active and passive open spaces in accordance with Appendix One: Scheme Map WUW Master Plan. • To identify, promote and protect WUW’s unique sense of place, social, cultural, ecological and hydrological character. • To protect and preserve the native cultural and historic landscape elements in WUW. • To protect and enhance valued remnant vegetation and habitats and ensure proper consideration is given to their presence in planning, designing and constructing development. • To create new, and enhance existing, ecological and human movement corridors, and ensure development positively contributes to the visual and environmental amenity and unique landscape character of WUW. • To provide a balance between conservation, amenity and public recreation in the planning and development of WUW. • To help foster the health and well being of future residents of WUW through access to a high quality sustainable natural and cultural environment. • To ensure the safety and surveillance of passive and active open spaces within WUW are delivered through appropriate structuring and design. • To facilitate the connection of physical and social neighbourhoods within and surrounding WUW, encouraging community interaction within an ecological setting. • To provide a link to the associated WUW Policies on Public Design and Urban Water Management and the Place Codes. • To provide where necessary a link to the WUW Developer Contribution Scheme to ensure the development of:- o Wetland buffer areas and landscape elements identified in the Foreshore Management Plan; and o Passive and active open space areas of appropriate quality and quantity, provided in a timely and cohesive manner in accordance with the WUW Master Plan.

1.4 Structure of Document

The structure of this LIMS document is as follows:

• Section 1 provides an introduction to the LIMS. • Section 2 outlines the existing environment that is specific to Precinct K. • Section 3 outlines general landscape principles as well as specific information regarding the reason for and planning of landscaping and irrigation within Precinct K. This section also addresses revegetation, retention of native flora and the integration of Public Open Space (POS) areas. • Section 4 details the treatment of POS and the location of areas to be revegetated. • Section 5 provides specific information which will assist future landowners to implement the LIMS through detailed landscape design and management plans that comply with this LIMS. • Section 6 provides guidance on reporting to occur in association with the LIMS. • Section 7 indicates the responsibilities of individual landholders in adopting this LIMS.

This document has been prepared by Cardno for Peet who are the main landowner representative for Precinct K. It has been prepared in close consultation with the following project team:

• McNally Newton Landscape Architects; • Taylor Burrell Barnett - Town Planning and Urban Design; • Emerson Stewart - Civil Engineering; and • Bruce Aulabaugh - Traffic Planning.

2. EXISTING ENVIRONMENT

2.1 Climate

The Master Plan area experiences a Mediterranean climate having wet, mild winters and warm, dry summers.

Annual rainfall recorded at the Armadale Post Office (Bureau of Meteorology Site No 9001) has been measured since 1908, and shows a maximum annual total of 1367mm in 1917 and a lowest annual total of 499mm in 1914. The long-term average for the station is 869mm (1908-2003) with a more recent average of 810mm between 1975 and 2003.

Over the summer period (December to February), the average summer rainfall for the Master Plan area is 30mm (3% of annual total) compared to 154mm and 298mm (25% of annual total) for Sydney and Melbourne respectively. Therefore, this means in relation to other capital cities in Australia, Perth has a very dry summer with little annual rainfall occurring in this season.

Windy conditions are experienced from late winter through spring and summer. The prevailing winds in July and August are west, northwest and north, while summer winds deviate from the southwest through to the south and east in the typical anti-cyclone cycle.

2.2 Landforms

The Master Plan area is situated on the Swan Coastal Plain. The Swan Coastal Plain is generally flat, approximately 20 – 30kms wide and consists of a series of geomorphic entities running parallel to the coastline. The coastal plain is low lying, often swampy with some dunes and therefore the soils predominately consist of recent sands or swampy deposits (Beard, 1990).

The Master Plan area has a generally flat character with the main topographic variation associated with the Wungong River. The landscape is highly modified as it has been mostly cleared for agricultural and grazing purposes. The Master Plan area is located within four different landform units. These are the Southern River, Beermullah, Guildford and Forrestfield landform units (Churchward and McArthur 1980).

Regional landform mapping indicates that the majority of Precinct K consists of the landform unit Beermullah (Bm), described as “soils located in poorly drained plains comprising saline and sodic soils with well structured B horizons (solonetzic soils), bog iron ore and some shallow sands over bog iron ore” (Churchward and McArthur 1980).

2.3 Topography

The Master Plan area is relatively flat and has limited notable topographic characteristics. The low-lying wetlands and drainage lines provide some visual relief, but it is noted that

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

there is relatively little change in elevation west of the Wungong River, where Precinct K is located. The natural surface height within Precinct K ranges from approximately 24 Metres Australian Height Datum (ADH) along the western edge of the precinct to 28 Metres AHD along the eastern edge, and gives Precinct K a slight westerly aspect. Precinct K is boarded to the north by the Wungong River. The Wungong River in this area is highly modified and flows gently through the landscape without notable topographic relief from flat agricultural land to the south. Topographic contours across Precinct K are shown in Figure 2.

2.4 Soils

As outlined above, Precinct K is located on the Swan Coast Plain. In terms of geomorphology, the Swan Coastal Plain consists of the Pinjarra Plain and three dune systems (Quindalup, Spearwood and Bassendean) of differing ages of deposition and with soils at different stages of leaching and formation. Precinct K is located within the Pinjarra Plain.

Regional geological mapping over Precinct K (Gozzard 1986) indicate the soil types evident within Precinct K include “Sand”, which occurs over sandy clay to clayey sand of the Guildford formation and “Sandy Clay” which consists of white-grey to brown fine to course- grained subangular to rounded sand, clay of moderate plasticity gravel and silt layers near the scarp. The distribution of soils units across Precinct K are shown on Figure 3.

2.5 Surface Water

The Master Plan area is located primarily within the catchment of Southern River, with the southwestern portion draining to the Peel Harvey catchment (JDA 2004). The Wungong River is the main watercourse within the Master Plan area and flows in a north westerly direction toward Southern River. The Wungong River starts as a narrow channel that is fed from flows originating in the Darling Scarp and broadens as it passes through the alluvial fans deposited at the foot of the Scarp. The river passes through a series of natural floodplains and man-made channels until adjoined by the Neeriden Brook South then Neerigen Brook North in the proximity of Armadale Road.

Wungong River flow is currently regulated by the Water Corporation’s Wungong Dam, located approximately 8km upstream of the Master Plan area (JDA 2004). Regulation of the Wungong River for public water supply purposes, commenced in 1925 with a pipehead dam, and the current dam has been in operation since 1979. Storage capacity of the dam is 60 GL (or million cubic metres) and regulation is in excess of 80% of the long term mean annual flow of approximately 25 GL.

A network of Water Corporation, local authority and private drains exists throughout the Master Plan area. The Birrega drain flows though the southern portion of Precinct K and is shown in Figure 4.

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

The entirety of Precinct K is also classified as Multiple Use wetlands and this is further discussed in Section 2.6. The foreshore reserve for the Wungong River as shown in the WUW Master Plan is also shown in Figure 4.

As mentioned previously, the Wungong River is part of the Southern River Catchment. The Southern River is a natural river system that commences at the confluence of Wungong River and Neerigen Brook (North Drain) and flows into the Canning River near the Fremantle Road Bridge in Gosnells. It is fed by a number of drains and natural waterways and contributes the greatest volume of water (approximately 30%) of any tributary to the Canning River. The Swan River Trust monitors nutrients within the system and nutrient concentrations are of particular concern for this catchment as it flows through historic agricultural land and is a known source of nutrient discharge.

2.6 Wetlands

Areas of wetlands have been mapped previously by Hill et al. (1986) across the entire Swan Coastal Plain. This mapping has been converted into a digital dataset that is maintained by the Department of Environment and Conservation (DEC) and is referred to as the “Geomorphic Wetlands of the Swan Coastal Plain” dataset. This dataset has become the key wetland reference information for the Swan Coastal Plain. This dataset contains information on “geomorphic wetland types” and assigned “management categories” that guide the ultimate management approach for each wetland area. The management categories now adopted by the DEC are described below in Table 1.

Table 1: Wetland management categories and management objectives

According to the Environmental Review (ATA 2006a), the entirety of Precinct K is classified as a Multiple Use Wetland (MUW). MUW areas are afforded no statutory and minimal policy protection by the EPA. The prevailing policy framework focuses on ensuring that all

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

reasonable measures are implemented to retain the wetland’s hydrological and other wetland functions. Generally speaking MUWs require no specific protection through the Western Australian environmental planning and approvals frameworks.

The Wungong River flows along the north-eastern boundary of the site and is also classified as an area of MUW. This area is significant because as it is part of the Wungong River and has key ecological and hydrological functions within the Master Plan area. The Wungong River acts as an ecological corridor and provides potential habitat for native fauna in the area.

2.7 Flora and vegetation

2.7.1 Historic Flora and Vegetation Surveys

A Flora and Vegetation assessment was undertaken by ATA in October 2006 for the Master Plan area and was documented in the report Flora and Vegetation Assessment Brookdale Redevelopment Area 2006 (ATA 2006b). This document outlined that a large proportion of the Master Plan Area has been cleared for a variety of purposes. According to broad scale mapping, (Churchward and McArthur, 1980) the remnant vegetation belongs to the Southern River, Guildford, Forrestfield and Beermullah Vegetation Complexes.

Precinct K is mostly cleared as a result of clearing for historic farming purposes and has been extensively grazed by livestock. The vegetation assessment (ATA 2006b) outlined that there are a few patches of remnant vegetation within Precinct K. The vegetation complex that occupied most of Precinct K prior to European development was the Beermullah complex: “A mixture of low open forest of C. obesa and open woodland of C. calophylla – E. wandoo – E. marginata. Minor components include closed scrub of Melaleuca spp., and occurrence of Actinostrobus pyramidalis”.

It was also noted in the Environmental Review (ATA 2006) that there was a small area of Low Open Woodland (MpCcLOW), which was the only section of vegetation within Precinct K classified as “Good” or better. Figure 5 and 6 shows the condition rating of the vegetation within Precinct K as shown in the Flora and Vegetation Assessment (ATA 2006b). This area was dominated by pasture or private gardens, with scattered native and non-native trees and shrubs. The areas of remnant vegetation were dominated by Melaleuca preissiana with scattered Corymbia calophylla and Melaleuca thuphilphyllaa over a Tall Open Shrubland to 4m dominated by Kunzia gibbrescens and Melaleuca thynoides with occasional Acacia fulchella over an Open habitat of Zentideschia athiopic and Juncus pullicus murate fiaccinta over introduced grasses. The vegetation around Wungong River was classified as “Good-Degraded” and there was a small patch of remnant vegetation in the south of Precinct K that was classified as “Degraded-Good Degraded”, with the remainder of Precinct K classified as “Completely Degraded”.

2.7.2 Detailed Surveys for Precinct K

In addition to the broad scale Flora and Vegetation Assessment (ATA 2006b), further site specific surveys were undertaken within Precinct K. This included two surveys by Cardno and one by Arbor Logic, both of which were conducted in 2008.

The subject site was traversed on foot by a botanist and environmental scientist from Cardno on the 1st February 2008 and a follow-up survey was conducted on the 19th February 2008 to gather data for the initial tree survey within Precinct K. In addition to this, Wungong River was traversed on foot by a botanist and environmental scientist on the 1st of April 2008. This information was used to develop priority ratings for the patches of remnant vegetation, which are shown in Figure 7 and 8. The data from these surveys is presented in the document Precinct K: Flora and Vegetation Assessment and Tree Survey (Cardno 2008) and Lot 1 Hilbert Road, Brookdale (Arbor Logic 2008) (See Appendix 2). A summary of all the information presented in these documents is presented below.

Cardno found limited ecological values remaining within the subject site as the area has been largely cleared for historic agricultural uses and heavily grazed. Vegetation condition across Precinct K ranged from “Good-Degraded” to ‘Completely Degraded” with only a small patch of vegetation within the northern portion of Lot 5071 in “Good-Degraded” condition. This was in variance to the data presented by ATA Environmental (2006b), which described the patch of Low Open Woodland (MmCcLOW) in the western portion of Precinct K as in ‘Good’ condition, yet when assessed in 2008 by Cardno was found to be ‘Completely Degraded’. The vegetation condition in the remainder of Precinct K was rated as ‘Degraded’ to ‘Completely Degraded’. The original structure of the vegetation has been highly modified and all that remains are a number of overstorey tree species.

Given these findings, it was considered difficult to recommend retaining any areas based on their ecological value alone, therefore the retention of vegetation should be based on ecological and aesthetic value. The aesthetic values of the trees within the subject site were determined by a number of attributes such as height, health, colour and shape. Trees that are mature, tall, and healthy and have a diversity of colour and shape were given a higher aesthetic rating compared with smaller trees with higher stress levels, lacking any striking features.

The trees rated according to aesthetic values are listed in order of value below:

• High - Large mature exotic Eucalyptus species, and a number of native Casuarina obesa and Agonis flexuosus trees that occur along the boundaries of lots 103, 104 and 105 and a number of large specimens occurring within the lots;

• Medium - Large mature Casuarina obesa (Sheoak) and Corymbia calophylla (Marri) trees;

• Medium to Low - Denser pockets of Casuarina obesa within Lots 105 and 106 and large mature Melaleuca preissiana within Lot 5071; and

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

• Low – two small pockets of small Melaleuca rhaphiophylla trees on Lot 106 and Lot 5071 and a small dense pocket of Melaleuca preissiana trees on Lot 5071.

The ecological value of the vegetation associated with the Wungong River within Precinct K is minimal due to the limited number of native species present, with the area described as largely cleared and degraded as a result of historic agricultural practices. Most of the original riparian vegetation has been historically removed, except two native tree species, Eucalyptus rudis and Melaleuca rhaphiophylla and one native sedge species, Bolboschoenus caldwelii. In addition, the weed species Cynodon dactylon (Couch grass), Zantodeschia aethiopica and Gomphocarpus fruticosus were found adjacent to the river. These species are ‘Declared’ weeds under the Agriculture and Related Resources Act (1983). Despite this limited number of native species, the remaining trees provide other functions, which include the stabilisation of the river bank by increasing the strength of the bank material with their roots. A stabilised bank reduces the likelihood of erosion occurring, reducing sediment transport into the river. In addition to bank stabilisation, they also provide limited habitat and food resources for bird, reptile and insect species.

2.8 Fauna

The majority of the Master Plan area comprises paddocks for pasture and is highly degraded. Consequently the habitat available is generally highly degraded and fragmented. The report Vertebrate Fauna Assessment – Brookdale Redevelopment Area (ATA 2006c) outlines the findings from a Level 2 fauna assessment undertaken across the Master Plan area. The report suggested that most of the remaining areas of potential fauna habitat are generally small in area and mostly isolated with only a few sizable remnants that are relatively undisturbed and considered to be in good condition. There were no key fauna habitats identified within Precinct K.

Riparian vegetation associated with the Wungong River and the fauna habitat along the river varied from “Good” to “Degraded” condition. The vegetation was found to be mainly dominated by Melaleuca sp., Flooded Gum (Eucalyptus rudis) and occasionally Marri (Corymbia calophylla). There is very little to no understorey and it is mostly introduced grasses. The Wungong River and its associated vegetation provide a key linkage corridor through the Master Plan area. The overstorey trees that are evident along the banks of the Wungong River along the northern boundary of Precinct K are likely to still provide habitat for local birds and some mammal species such as possums and bats.

2.9 Aboriginal Heritage

A full ethnographic and archaeological investigation was conducted by Tempus Archaeology in 2006 for the Master Plan area. This investigation discovered a number of new isolated archaeological sites within Precinct K and further investigated one previously recorded Aboriginal site (Tempus 2006).

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

Two new sites (lodged with the Department of Indigenous Affairs (DIA)), DIA 26092 (BAS- 10) and DIA 26094 (BAS-15) and one isolated artefact (BIF 028, not lodged with the DIA as a site) were found within Precinct K during this investigation. One previously recorded ethnographic site DIA 3512 Wungong Brook was also identified.

DIA 26094 is comprised of a stone artefact aggregation located on an isolated sandy rise and has some further research potential. This site is currently protected through strategic POS location within the Master Plan. DIA 26092 is comprised of a minor archaeological sample with little future research potential and is recommended to be managed in accordance with a regime of ‘preservation by record’ (Tempus 2006).

BIF-34 was described by Tempus Archaeology (2006) as an isolated artefact with little research potential. This artefact has been fully recorded and no additional action is proposed. This site has not been lodged with the DIA.

Wungong Brook (DIA 3512) is described as a mythological site and listed as permanent on the DIA register. The brook is located within an area designated Foreshore Reserve on the Master Plan and is proposed to be managed in accordance with environmental protocols outlined in the Wungong Urban Water Redevelopment Area Foreshore Management Plan (ENV Australia 2007).

Based on the Aboriginal heritage investigations undertaken to date, further Aboriginal Heritage Investigations of Precinct K will be required. Section 18 approvals will be necessary to disturb any Aboriginal sites identified within Precinct K. These investigations are in the processes of being completed for Precinct K and will support the lodgement of Section 18 applications to disturb Aboriginal sites within Precinct K, with the intention to occur prior to subdivision.

2.10 European Heritage

A cultural heritage survey of the Master Plan area has been undertaken. This survey included a desktop review of available documentary resources and a physical survey of the Master Plan area and is outlined in the document Brookdale Master Plan – Cultural Heritage Survey (Heritage and Conservation Professionals, 2004). The physical survey of the Master Plan area comprised a drive through survey that was limited to places that were visible from the road or were previously identified in existing heritage lists and reports. No private properties were accessed during this survey. Places of heritage significance were assessed on the basis of their aesthetic, historical, social and scientific significance as defined by the Heritage Council of Western Australia.

Based on this cultural heritage survey, there are currently no places located in the Master Plan area that are included on the Register of Heritage Places and therefore there are no statutory requirements under the Heritage of Western Australia Act 1990.

3. PLANNING AND DESIGN

3.1 Outline of LSP

An LSP has been prepared by Peet for Precinct K (Figure 9) of the ARA’s WUW Master Plan. It covers an area of approximately 177.84 ha and is bounded by the Wungong River to the northeast, the existing Peet Adios special residential subdivision and Hilbert Road in the southeast, Rowley Road and a proposed “living stream” to the south, Tonkin Highway to the west and a proposed “park avenue” to the north. The Precinct comprises a number of landholdings, however the largest of these are owned by two Peet syndicates, being the Peet Forrestdale and Peet Oakford Syndicates. Precinct K will be developed around a range of open space opportunities. There are a range of open space locations within the LSP, which include neighbourhood parks, the Wungong River foreshore reserve, park avenues and living streams. Treatments and design aspects of the open space areas within Precinct K are discussed in more detail in Section 4.

The design of the Master Plan took into consideration the location of significant environmental attributes of the site. The location of Public Open Space (POS) and reserves coincides with areas of high ecological value such as wetlands and remnant vegetation. The park avenues are positioned not only to provide aesthetic appeal, but to connect the areas of POS and vegetation and to encourage ecological corridors throughout the Master Plan area, to allow for the movement of fauna.

The LSP builds on these principles whilst providing a more detailed development concept for Precinct K. The locations of POS areas have been strategically placed, allowing for the retention of vegetation and Aboriginal Heritage sites. The Wungong River foreshore has been focused on to enhance this local amenity. A living stream and numerous park avenues have been incorporated into the LSP to enhance the aesthetic appeal of the precinct and to encourage the retention and enhancement of ecological corridors. The overall design of the LSP addresses the principles outlined in ARA policy and follows the broad scale planning provided by the Master Plan.

3.2 Landscape Principles

A number of landscape principles have guided the design and proposed treatment of landscaping and irrigation within Precinct K. These principles are in accordance with the Revised Draft Integrated Open Space and Landscape Policy (ARA 2008) and the requirements outlined in Ministerial Statement 762. These principles are outlined further below.

3.2.1 Public Open Space

Public Open Space (POS) is the focal point for the development’s creation of character, community gathering and activities, informal recreation, public facilities, and visual relief from the urban form. The design of these POS areas aims to locate various facilities and

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

feature elements at focal points which are easily visible from vehicles and by pedestrians. This maximises passive surveillance and clearly conveys the facilities available. All passive and active POS areas within Precinct K are integrated and linked through the implementation of park avenues, a living stream and an overall footpath system.

As outlined in the Flora and Vegetation and Tree Assessment (Cardno, 2008), there are areas that have been identified within Precinct K that carry a higher priority for vegetation retention. The POS areas have been strategically placed over these identified areas. This will provide both aesthetic and ecological functions for Precinct K. The depth of fill required in the final development will determine the extent to which this vegetaion is able to be retained. It may be the case that some of these areas are lost if high levels of fill are required.

Planting in POS areas will consist mainly of native species which will enhance the original nature of the site and reduce the amount of turfed areas over the Precinct. In general there will be an emphasis on native plantings as opposed to turf. In areas where it is necessary to have turf there will be irrigation and fertiliser management measures applied.

The Wungong River will be a key feature within Precinct K. This area will not only provide for the retention of vegetation and an ecological corridor, but will also provide key recreation nodes which will help enhance the natural character of Precinct K.

3.2.2 Recreation Facilities

Recreation facilities throughout Precinct K will cater for a wide range of residents. There will be off the shelf discovery and learning playgrounds catering for children two to five years old as well as one adventure level playground catering for children five to 14 years old. Shelters and arbors will be established to cater for parents and informal gatherings as well as BBQs and gathering spaces.

Integrated path systems and boardwalks will create areas suitable for walking, dog walking, cycling, skateboarding and similar. Informal open recreation spaces will be available for a wide range of uses as well as formal recreation spaces associated with schools and organised sports for all ages. There will be fitness trails for active persons and smaller contemplative spaces for less active persons, suitable for all ages.

3.2.3 Vegetation Retention

The retention of existing vegetation in defined locations will cater for retention of existing habitat, preservation of the site’s natural assets and provide visual relief in an urban environment.

Whilst most of the vegetation on site has been degraded through impacts associated with past land uses, stands of vegetation will be retained to deliver enhanced environmental outcomes.

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

As outlined in flora and vegetation survey (Appendix A and Appendix B) there are areas of vegetation with high retention priority, these areas have been strategically located within POS areas as previously mentioned.

Detailed landscape plans will be submitted during subdivision, and these plans will clearly identify vegetation which will be retained. The POS descriptions in Section 4 provide detail on the retention of vegetation and the treatment of these POS areas.

The retention and protection of existing vegetation within POS and reserves will be an important consideration during construction. Retention and protection strategies shall include temporary fencing and signage to all retained areas and individual specimen trees and ongoing monitoring during construction.

The Wungong River is the key ecological feature within Precinct K and there will be an emphasis on the retention of vegetation where possible along the Wungong River and within the associated foreshore reserve. The Wungong River has historically been “channelised’ and therefore in its current form is representative of a trapezoidal drain. Some alterations to its banks will be required to give it a more natural form. During this process there may be trees that are lost from the riparian zone. However, this area will be revegetated, which will improve the natural function and look of the river and contribute to the development of an ecological corridor within the area. The Wungong River will be the key vegetation retention area within Precinct K and there will be an emphasis on revegetation of the foreshore area as detailed in Section 4.2.

3.2.4 Proposed Landscape Planting

The provision of planting in public areas and streetscapes serves to provide character, shade, interest, habitat and a point of reference in major streets or feature locations.

The locations of public planting and types of vegetation will have a focus on native species with some exotics plants and shade trees at feature points. Exotic feature tree avenues will be planted in nominated street or entry locations. Turf will be planted to enhance formal or informal usable space and recreation areas.

Native habitat trees will be planted in nominated locations, and native avenue plantings will occur within residential streetscapes. There is proposed bushland and habitat regeneration in disturbed areas, namely the Wungong River foreshore reserve. Within the swales and watercourse, reed and sedge planting is to occur. These swales and watercourses include the Wungong River, the living stream and drainage swales within the park avenues and POS areas.

Proposed ecological restoration areas will be predominantly within the Wungong River foreshore reserve. It is also likely that some revegetation work will be undertaken within the living stream area, park avenues and possibly surrounding areas of Aboriginal heritage significance. Shrub planting will assist in screening and adding spatial definition to areas,

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

this includes groundcover planting on medians, planters and areas’ requiring clear view sheds.

The proposed mix of endemic native species and exotic cultural plantings in feature locations will provide a blend of character and define feature points. A blend of character will be provided by the variety in plant species, foliage colour, flowering characteristics and overall aesthetic value. In cases where deciduous species are utilised, maintenance practices will be incorporated to reduce the impact of decomposing leaves on the stormwater system and water quality. These will include minimal use of such trees, drain covers to reduce leaf litter entering stormwater systems and treatment of water in swales and basins before entering the Wungong River and living streams. Below, Table 2 and 3 outlines the species to be included. From these lists, deciduous species should not to be incororated within park avenues, living streams and the Wungong River foreshore reserve.

To ensure feature points achieve a high impact it will be important to define these areas through the use of mature plant species and species that differ somewhat from the surrounding area. Typically native trees are not available at a significant mature size and as such it is proposed to utilise mature exotic species where natives are not available to ensure a high level of finish is achieved within a short period of time.

Table 2 and Table 3 outlines species to be utilised within park avenues, POS areas and streetscapes. .

The ultimate selection and placement of species shall consider future maintenance requirements, public health and safety issues, service alignment and maintenance, promoting the survival and health of the vegetation and providing ongoing social and visual benefits.

The seasonal influence of shade on adjacent facilities and areas would be considered as well as passive solar benefits influencing adjacent built form and residential dwellings. Plant selections have been based on suitability to local climate, soils, rainfall and temperatures as well as reduced maintenance, trimming, pruning, fertilising and irrigation. Consideration would be given to the provision of seasonal visual colour and a seasonal food source to local fauna. Buffer screening will be provided to residential or sensitive areas where required.

Along major roads, planted trees will form a strong visual avenue, and not impede traffic flow, safety or sightlines. In residential streets, the roads may vary in character, however are characterised primarily as smaller scale pedestrian friendly environments. Therefore residential street trees will be of a smaller scale and will take advantage of passive solar principles allowing summer shade and winter sun.

3.2.5 Entry Treatments

The entry road design into a project provides direct access and expresses the design character of the project and conveys various detail treatments and materials. The entry treatments will connect the entrance areas to the rest of the development. The presence of street trees and landscaping will connect the entrance with areas of remnant vegetation within POS areas and planted vegetation within park avenues.

Street trees will reinforce the significant nature of these major roads by forming strong visual avenues where appropriate. Views to distant feature elements and close views of materials and details significantly enhance initial perceptions of the development. Landscape design options shall be tailored to meet all necessary civil design standards while expressing the projects design theme.

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

3.2.6 Drainage/Stormwater

The LSP for Precinct K aims to utilize water sensitive urban design principles. Water sensitive urban design recognises the linkages in the water cycle between residential development, stormwater systems and the quality of downstream ecosystems. Within Precinct K, this will include stormwater detention in POS areas to minimise downstream flows following major storm events and bio-retention swales to collect stormwater runoff. Swales/basins will also provide for multiple uses including recreation and storm water management. They also encourage fauna habitat creation. Reed and fringing vegetation will be planted to provide a nutrient stripping function. A species list outlining the species that will be used in the drainage basin planting areas is provided in Table 4 below.

The Local Water Management Strategy (LWMS) prepared by Emerson Stewart (Emerson Stewart 2008) outlines the water sensitive design within Precinct K and how drainage and stormwater will be dealt with across the various landholdings within Precinct K.

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

3.2.7 Irrigation Strategy

A general principle has been adopted throughout the planning stage to reduce the amount of irrigated areas within Precinct K. Turf areas require a high level of irrigation and have therefore been minimised with an emphasis on restoring native vegetation throughout Precinct K. Reduced irrigation use methods throughout Precinct K include reduction in areas of turf, avoidance of species which require extensive irrigation and the design of irrigation systems for efficiency (to be detailed at subdivision).

Irrigation, when necessary shall aim to incorporate elements of subsurface, drip and trickle water application methods, with water application based on seasonal need and a reduced number of areas under surface spray water application. As described above, water-wise principals will be employed to achieve a minimum 30% of POS not requiring irrigation. This will ensure that Precinct K meets the Department of Water guidelines that groundwater allocation be 7500 kilolitres/hectare/annum.

An internal non-potable water reticulation system (3rd pipe system) is proposed to be constructed within the Master Plan area for connection into a proposed Master Plan community bore distribution system. This is discussed further in Section 5.5 and in the LWMS (Emerson Stewart 2008). If this initiative has not been implemented at the commencement of development it is proposed to install groundwater bores utilising local groundwater to irrigate the public areas. Each of these bores and associated infrastructure will be designed and specified to suit local conditions. It is anticipated that the bores and associated infrastructure will be transferred to the City of Armadale following the two year developer’s maintenance period.

3.2.8 Water Wise Planting

In line with the overall principle to reduce irrigation water demands it is proposed that native species will be utilised wherever possible to minimise irrigation requirements. Soil conditioning will be employed to reduce leaching and increase soil moisture holding capacity. All garden beds will be mulched to reduce water loss through evaporation.

As outlined above there is a general principle throughout the landscaping of Precinct K to minimise turf within POS areas and this will reduce the irrigation and maintenance required. Turf will be used within areas of passive recreation along the park avenues, within some areas of POS and at selected locations along the Wungong River foreshore reserve.

3.2.9 Public Area Furniture

The provision of public area furniture will be in line with the intended use of POS and reserve areas. The inclusion of quality street furniture elements reinforces the intended design theory, develops a sense of community and ownership among residents and encourages and caters for outdoor use.

The location of street furniture elements will closely correspond with more intensive areas of human use, gathering and recreation. Basic functional requirements shall include the

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

local availability for the quick and cost effective installation, ongoing replacement and maintenance of installed furniture.

Public area furniture will have a robust design to minimise the effects of vandalism or weathering and appropriate fixing methods to allow maintenance and prevent theft. Colour will be defined but neutral where possible to enable the maximum blending with other site elements and have galvanised and powder coated finishes to maximise lifespan.

Elements shall provide a visually recognisable, clear and useful function. The types of street furniture envisaged would include, picnic settings, shade structures, bridges/causeways, BBQs, seating (formal and informal), rubbish bins, tree guards and bollards.

3.2.10 Public Art

The selection and installation of appropriate public art creates interest, social discussion and promotes a sense of community and ownership to public spaces. Public art can provide indigenous heritage, historic, social, cultural and environmental comment and act as a reference to define a local area, resident profiles and community values.

It is intended that public art be distributed at either high profile points or community gathering spaces to ensure its value in place making is maximised. Locations should include vista and axis views from roads or pedestrian paths and inclusion into playgrounds and picnic locations. Individual lighting may be desirable in some instances to provide focus to specific pieces and importance.

3.2.11 Maintenance Minimisation

A key consideration for all landscaped areas will be to minimise long term maintenance requirements given that these areas will ultimately be transferred to the City of Armadale. In conjunction with the detail design of public open space and verge areas to be vested and controlled by the Council, a maintenance minimisation review will be undertaken by the design consultant team to best reduce likely future maintenance costs at the time of subdivision detailed design.

The reduction of turf areas and use of native species will minimise the maintenance required throughout Precinct K. Native planted trees and revegetated areas will not only be water wise options but require low maintenance in comparison to highly landscaped and turfed POS areas.

3.2.12 Aboriginal Heritage

From the aboriginal heritage investigations undertaken Aboriginal Heritage Site DIA 26094 is the primary site to be preserved and will be included within the design of POS (Park 9) in accordance with ARA, Government guidelines and Aboriginal representatives. The treatment of this POS area is further discussed in Section 4.4.

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

Consideration will be given to the protection and enhancement of this local Aboriginal heritage site. The site will be treated in a sensitive manner with an emphasis on increasing awareness of the cultural importance of the site through the strategic use of interpretive signage and educational material. The site will be linked strongly to the surrounding landscapes and will form an important part of the cultural and environmental experience for local residents.

3.2.13 Ecological Corridors

Precinct K is consistent with the “Wungong Green Corridors” as outlined in the Master Plan. The design of these corridors through out the Master Plan area aims to create corridors to link ecological habitats. This will be achieved through the use of park avenues, which will have planted trees along the edges, the creation of a living stream and rehabilitation of the Wungong River foreshore reserve.

The Wungong River is considered a key area within Precinct K to ensure ecological linkage values. This area will be reserved for conservation and recreation uses and revegetation will occur along the foreshore to preserve and enhance ecological values. The rehabilitation and revegetation of the Wungong River foreshore will use native local provenance and an initial species list is listed in Section 5.4.4. The provision of a living stream corridor joining the Wungong River foreshore reserve within Precinct K and the restoration of this area will encourage the use of this as an ecological corridor, enhancing fauna movement throughout the precinct.

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

4. AREAS OF POS AND RESERVES

The key POS objective is to provide a readily usable, aesthetic and liveable environment to potential residents from the beginning. Landscaped open space areas shall incorporate features and facilities to encourage both residential growth and to provide public, aesthetic and site character building amenities to residents. Landscape works shall contain and maximise aesthetic and functional uses where possible.

POS areas have been strategically located within areas that have remnant vegetation and other significant values, such as heritage sites and areas identified as ecological corridors.

The areas of POS within Precinct K have been separated into broad categories based on their specific treatments and design for the purpose of discussion in this LIMS. Figure 10 shows the location of these areas and includes the following:

• park avenues; • Wungong River and foreshore; • living streams; • neighbourhood parks; • primary school and local open space; • high school and local open space; and • road reserves.

The treatment of these areas is addressed in more detail below.

4.1 Park Avenues

The linear park avenues will provide a “Multiple Use Corridor” providing passive recreation and drainage management functions. The park avenues will provide a drainage function through Precinct K, which will involve the placement of drainage swales within these areas. To enhance the uptake of nutrients within the drainage swales it is expected that the park avenues will combine a range of native plants with an emphasis placed upon the use of suitable reed and sedge species as outlined in Section 3.2.4.

Native trees, as specified in Table 2 and Table 3, will define the area. Trees will be formally and evenly spaced and will be in line with the side boundaries of the park avenues. Some informal tree planting will occur throughout the avenues. Planted trees and revegetation of the central area of the park avenues will provide an ecological linkage system between the POS areas. No deciduous species should be utilised within park avenues, these have been highlighted in Table 2 and Table 3.

Dual Use Paths (DUPs) will also border the boundaries of the park avenues and will connect to the various neighbourhood parks and the Wungong River foreshore path systems. In accordance with ARA policy, the park avenues follow those delineated on the

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

WUW Master Plan and form a matrix to interconnect movement, parkland and drainage networks.

Figure 11 represents a typical cross section of the avenues and is representative of the treatment the majority of park avenues will receive. There will be a DUP on either side which will provide a hard edge to the system. There will be direct lot frontage onto the park avenues providing passive surveillance. The majority of the park avenues will be dedicated to native revegetation with native shrub plantings on the banks and native reed and sedge planting on the base of the drainage conveyance channel. This will also enhance nutrient uptake.

Figure 11 Park Avenue Cross Section A

Figure 12 demonstrates an area within a park avenue which is aligned with a road. There is still a DUP on both sides of the park avenue, native plantings along the centre and direct lot frontage. There will be feature tree planting along the road reserve and car parking on the boundary of the park avenue.

Figure 12 Park Avenue Cross Section B

At several points along the park avenues it will be necessary to have bio-retention basins with native reed and sedge planting at sub-soil drainage outlet points. An example of this is below in Figure 13.

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

Figure 13 Park Avenue Cross Section C

Some areas within the park avenues will support areas for passive recreation. This will involve turfed areas and parkland trees. Figure 14 indicates roll on turf to the bank at 1:6 maximum grade to allow for passive recreation to the base of the swale. In addition to this there would be a 4 metre wide, 500 millimetre deep drainage channel with rock work, native reed and sedge planting and irrigated native shrub planting to the bank.

Figure 14 Park Avenue Cross Section D

4.2 Wungong River and Foreshore

The Wungong River and foreshore reserve will be developed and managed for the purposes of conservation, water quality protection and passive recreation, in line with the requirements outlined in the Foreshore Management Plan (ENV 2007). The philosophy will be to rehabilitate a large portion of the currently degraded foreshore with native species and to provide recreational opportunities for future residents. The rehabilitation of this area will enhance the ecological corridor that the Wungong River naturally provides throughout the Master Plan area.

Although the emphasis of the Wungong River foreshore reserve will be on rehabilitation, there will also be passive recreation opportunities within the foreshore reserve that will include DUPs, less formalised walk trails, boardwalks and shelters. Interpretative signage will be located along the footpath and boardwalk network informing users of the importance of the wetlands and highlighting local flora and fauna.

The stabilisation and revegetation of the Wungong River will be undertaken to restore the existing creek line. Existing significant vegetation will be retained and revegetation using indigenous flora will aim to create a variety of wildlife habitats. Areas of restoration will be linked to wider path networks, boardwalks and shelters. Rehabilitaion will be undertaken in line with Section 5.4.4, described further within the LIMS.

The Wungong River has been historically “channelised’ and therefore is representative of a trapezoidal drain in its current form. Some alterations to its banks will be required to give it a more natural form. During this process there may be trees that are lost from the riparian zone. However, this area will be heavily revegetated and will contribute to a more natural looking and functioning area that will be an effective ecological corridor.

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

Stormwater runoff from rainfall events greater than the 1:100 events will overflow from the primary infiltration swales within the development site into the Wungong River foreshore reserve. Here it will be intercepted by vegetation before entering the river.

The majority of the Wungong River Foreshore Reserve will be dedicated to revegetation of the riparian zone. Figure 15 shows a typical cross section of the rehabilitated Wungong River and associated foreshore reserve.

Figure 15 Cross Section A: Wungong River and Foreshore Reserve

In some instances, private lots will interface directly with the Wungong River foreshore reserve. To protect foreshore values and ensure passive surveillance, a DUP will provide a hard-interface between the suburban area and foreshore, while the lots will be serviced by a laneway. The laneway will ensure that houses are orientated such that passive surveillance of the foreshore reserve is achieved at detailed design stages. It is also likely that Detailed Area Plans will be required as part of the subdivision process in these areas.

There will be some areas along the Wungong River with feature shelters and BBQ facilities and Figure 16 shows an example of this type of passive recreational node. This cross section also shows an elevated residential lot with screen planting to the frontage of the lot and a turf and dual-use path buffer.

Figure 16 Cross Section B: Wungong River and Foreshore Reserve

At selected locations along the Wungong River there will be foreshore nodes in which a key feature is a viewing platform to encourage interaction with Wungong River and native revegetation. Figure 17 shows an area of passive recreation along the Wungong River. Areas for passive recreation will be separated from rehabilitated areas with fencing.

4.3 Living Streams

Living streams will provide not only a drainage function but also a variety of ecological zones and restoration opportunities. These will include open woodland and parkland, revegetated riparian systems, shelters and boardwalks and an integrated path and walk trail network that links with the wider path system. There are two areas within Precinct K that will be subjected to treatment as a living stream including Birrega Drain on the southern boundary of the Precinct.

Planting will consist of native and endemic species, as outlined in Table 4 with a variety of tree, shrub, groundcover, reed and sedge species.

All restoration and construction works of the meandering stream will be as outlined in the Department of Environment’s River Restoration guidelines. The living stream will include a DUP on both sides of the living stream and a walking trail. There will be native shrub planting on banks and native reed and sedge planting to enhance nutrient uptake. Creek stabilisation will be incorporated into the design and a variety of tree species will be used to provide a diverse tree canopy. Figure 19 shows a typical cross section of the living stream with mostly revegetated areas and a passive recreational node.

Some areas along the living streams, as outlined in Figure 20, will include parkland turfed areas for passive recreation.

Figure 20 Living Streams Cross Section B

Figure 21 below shows the cross-section for the treatment of Birrega Drain as a living stream. In accordance with ARA policies, Birrega Drain will include similar features to the living streams described above while retaining the ability to convey water as required by the Water Corporation. This living stream will combine with a park in the southern portion of Precinct K to create a formal passive recreation area, with play equipment, BBQ’s, DUPs and boardwalks.

avenues to provide a fully integrated path network. Avenues of trees and minimal shrub planting are preferred. Planted species will be a mix of natives and some exotic species at high impact points. Drainage areas may be required in these open spaces, and where provided will be landscaped basins, serving a recreational and amenity function. Drainage swales within POS areas will likely be turfed. A brief outline of the character and design of each Park located within Precinct K is given below.

Park 4 is situated on the western edge of Precinct K, adjacent to Tonkin Highway. It is a very small neighbourhood park and will include passive recreation and native planting with a footpath connection. There is no remnant vegetation within this site.

Parks 5 and 6 are located adjacent to the living stream on its eastern side. These mediums sized parks will be used for passive recreation and will include native planting and some turf. There will be a provision of furniture, a feature shelter and a DUP system. The DUP system will connect the park with the adjacent living stream.

Park 7 is located just south of Rowley Road over a patch of Melaleuca preissiana and adjoins a park avenue. This medium sized park will be used for passive recreation with native planting and some turf. The DUP system will connect the park to the adjacent living stream. Within, there will be a provision of a feature shelter, furniture and possible picnic and BBQ facilities.

Park 8 is located south of Rowley Road on the southern boundary of Precinct K. This medium sized park will be used for passive recreation and will include native planting and some turf. Consideration should be given to the retention of existing remnant vegetation, including Melaleuca rhaphiophylla. There will be provision of furniture and a DUP system.

Park 9 is located in the north east of Precinct K and will focus on the retention and enhancement of the existing Aboriginal heritage site (DIA 26094). There will be a provision of interpretive signage and educational material to inform people of the Aboriginal heritage values associated with the site. The park will include native planting with some turf area dedicated to passive recreation. Formal use of shade trees will be employed and the provision of feature shelter and furniture. A DUP will connect the park to the adjacent park avenue.

Park 10 is a large park located to the south of the primary school and will be used for passive recreation and will include native planting and some turf. Consideration shouldl be given to the retention of existing remnant vegetation. There will be a provision of furniture and a DUP system.

4.5 Primary School and Local Open Space

Formal active recreation facilities will be associated with the primary school located within Precinct K. These open space areas will allow for the shared use of active recreation facilities with both the wider community and the primary school. Typically the primary

school will include a football and cricket oval, full sized mixed use sports court, cricket nets, high quality landscaping, turf and shade trees.

4.6 High School and Local Open Space

Formal active recreation facilities will be associated with the high school located within Precinct K. This open space area will allow for the shared use of active recreation facilities between both the wider community and the high school. Typically the facilities associated with a high school site would include: a football and cricket oval, soccer and hockey pitches, full sized mixed use sports court, basketball/netball and tennis courts, cricket nets, high quality plants, turf and shade trees

4.7 Road Reserves

Road reserves will be treated to provide an attractive, shaded and safe environment for pedestrians and cyclists and shaded areas for vehicle parking. There are several different treatments that will be implemented for road reserves within Precinct K, which are described below. Road reserves allow for footpaths on both sides of the road and are important in maintaining tree lined areas within Precinct K, contributing to the aesthetic attributes of the Precinct.

Figure 22 shows an area with a 16 metre road reserve and a 1.8m wide footpath to both sides of road and then turf to the verge. There will be native trees planted on 2.7 metre offset from lot boundary and trees will be located central to the residential lots.

The road avenue along Hilbert Road, shown in Figure 29, will aim to preserve a row of existing trees, comprised of predominantly Eucalyptus rudis. This will be achieved through the use of a four metre no trenching zone to protect the root zones of the trees and to ensure their long-term survival. In combination with the trees already present, there will be a total of two rows of native trees on both sides of the carriageway and the planted trees will be spaced at 8 metre maximum centres where possible to ensure a continuous canopy is created.

4.8 Lot Landscaping

While there are numerous separate land owners within Precinct K, it is generally expected that individual developers will provide incentives for lot purchasers to follow environmentally sound guidelines for the installation of all lot landscaping within the development area, with particular focus on water-wise landscaping.

Emphasis will be placed on the utilisation of native water wise plants and trees, water wise irrigation techniques, 5-star rated water-wise appliances and minimising turf use. This is to be in line with the overall aesthetics and theme of the development area.

5. IMPLEMENTATION, MONITORING AND MAINTENANCE

5.1 General Aspects

Implementation, monitoring and maintenance of the various requirements outlined in this LIMS will be the responsibility of the individual landowners within Precinct K as they seek the development of their landholdings. It is envisaged that this plan provides a framework for how land will be developed at the subdivision stage. Detailed plans lodged with individual subdivision applications can be assessed against the requirements outlined in this LIMS.

Maintenance schedules will depend on the areas of POS and/or reserves in question and will need to be case specific. The maintenance schedule will extend for two years after works are complete. Detailed maintenance schedules will be submitted at subdivision stage outlining specific maintenance activities to be undertaken within Precinct K and the basis for undertaking them.

Monitoring of the landscaped and revegetated areas will not only determine the success of the implementation of this LIMS but help to determine effective and efficient irrigation and fertiliser requirements for these areas. Monitoring will be undertaken across Precinct K during construction and post construction stages. Monitoring and regular inspections will be required during construction to ensure that existing vegetation is protected during activities. The inspections will ensure that designated areas are cleared for construction and reserved areas of remnant vegetation are protected.

Post construction monitoring will assess the progress and success of the landscaped and revegetated areas. This will include areas such as the Wungong Foreshore and POS are protected.

Below outlines the implementation, monitoring and maintenance associated with applying this LIMS.

5.2 Dieback Management Strategy

Phytophtora cinnamomi, commonly known as ‘Phytophtora Dieback’ is a soil borne fungal pathogen that is a serious threat to the flora of Western Australia. Phytophtora dieback is spread through surface and sub-surface water flows. Consequently, the movement of infested water and soil play a key role in the spread of this pathogen. Human activities such as road building, earth moving, timber harvesting, wildflower picking, bush-walking, four-wheel driving, firebreak management, and planting diseased nursery stock have contributed significantly to the rapid and widespread distribution of the species (Dieback Working Group 2008; Centre for Phytophtora Science and Management 2008). Currently, there has been no Phytophtora Dieback observed within Precinct K. The Precinct is recognized as a low priority Phytophtora Dieback management area as it has

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

limited pockets of remnant vegetation. Although it is a low priority, certain measures need to be undertaken to maintain this status due to the high level of surface and sub-surface water within the area.

Some of these measures include: • Ensure machinery and equipment arrive on site mud and soil free; • Select firebreak locations low in the landscape to limit spread of pathogen; • Schedule activities that require soil disturbance during dry soil conditions (November – March); • Limit duplication of existing access ways; • Purchase plant species from nurseries with a Nursery Industry Accreditation; • Plant Phytophtora Dieback resistant species; • Where Phytophtora Dieback resistant plant species are not available or are planted, group species together to improve the management of the pathogen if it presents; and • Using fill certified as being free from the pathogen.

Throughout Precinct K, the greatest potential for infection will be as a result of soil being transported into the area during construction. Therefore management will primarily focus on hygiene, the clean entry and exit of vehicles and machinery to the site.

5.3 Fire Management Strategy

The Swan Coastal Plain has historically been susceptible to fires, which is a result of inherently flammable vegetation, dry summers, periodic drought and lightning ignitions. The fire season for the subject area corresponds with the summer months’ high temperatures and low rainfall.

The fire season can occur from September to April with the proclaimed bushfire season being between October and March. The proposed development falls under the Armadale jurisdiction for fire fighting operations.

Parkland areas within Precinct K will need to have controlled vehicle access and access to wells and other water resources to ensure firefighting vehicles have resources available in the case of a fire. There are no large areas of remnant vegetation within Precinct K that will pose a significant fire risk and therefore fire management is not a major consideration.

However, detailed plans will be submitted at subdivision stage and will show fire management provisions such as the location of vehicle access into the Neighbourhood Parks and Wungong Foreshore Reserve, water access locations and consideration for Phytophtora Dieback management. Vehicle access will be sited along paths to minimize disturbance to native vegetation. Confirmation is currently being sort for these requirements, from which the land developers will subsequently incorporate into future plans, as required to ensure compliance. Table 5 outlines fire management and maintenance actions below.

5.4 Landscape Management Strategy

It is widely thought that the local climate is undergoing a drying trend and that as Perth’s population grows and demand for potable water increases, consideration should be given to how water resources are currently utilised. Within Precinct K an overall principal in developing the area is to reduce the irrigation demands and maintain natural landscape and waterways to compliment the wider Wungong area. In line with this, the following approaches will be applied: • Utilising local and native vegetation; • Minimising water requirements for the establishment of POS; and • Minimising water requirements for POS maintenance

Local planning policies by the Eastern Metropolitan Regional Council (EMRC) and within the City of Armadale (ENG 14 and PLN 2.9) encourage the use of local native species and Geraldton sand-plain species to improve biodiversity within an urban setting. Increasingly local government is required to undertake development in a sustainable way, including the

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

protection and enhancement of local natural resources (EMRC 2008). In line with local government policy, local native species will be utilised where ever possible within the POS and landscaping of Precinct K.

Another set of design criteria promoted by the Water Corporation’s Water-wise Display Village program are described below: • The irrigation system shall be designed and installed according to best water efficient practices; • Within POS, garden beds and community areas are landscaped using ‘water-wise plants’, which are local native species that require less water inputs than exotic species; • Soil should be improved with a soil conditioner certified to Australian Standard AS4454, to improve water and nutrient retention capabilities; and • Garden beds should be mulched with a product certified to Australian Standard AS4454

It is envisaged that implementing these measures will add to effective and efficient landscape and irrigation practices within Precinct K.

5.4.1 Fences

In the Foreshore Management Plan, it is outlined that the location of the public access ways must be developed with strong regard for ecology and rehabilitated land, together with opportunities for environmental education and public awareness. Fencing should be located in areas that are degraded, and be placed around those areas that will be predominantly for conservation purposes. The Wungong River foreshore within Precinct K is the only area to undergo significant revegetation for conservation purposes. For this reason, the foreshore area is likely to be the only area to receive fencing treatments.

Fencing will need to be installed along the Wungong River foreshore reserve where there is an interface between rehabilitated areas and passive recreational nodes. This fencing should be adequate to discourage public and vehicle access and the DEC should be contacted for up-to-date advice on fencing specifications. Detailed plans will be submitted at subdivision stage and outline the exact locations of fencing along the Wungong River foreshore reserve.

5.4.2 Weed control

Throughout Precinct K, weed control measures will be implemented in newly landscaped areas and in areas of revegetation. This will involve spot spraying, manual removal and mowing. Weeds represent a major issue contributing to the degradation of native bush land areas and can prevent rehabilitation efforts. Weed species require control in order to maintain natural areas and their ecological integrity. In order to minimise the damage caused by weeds an Environmental Weed Strategy for Western Australia was developed (CALM,

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

1999). This strategy rates weed species according to a criteria based on invasiveness, distribution and environmental impacts.

Within Precinct K, weed control within the Wungong River Foreshore Reserve, the Living Stream and the Park avenues will be a major contributor to the success of revegetation. Of particular concern is the weed species Cynodon dactylon (Couch grass), which was identified as present on the water fringes of the Wungong River within Precinct K (Cardno 2008). Other species observed adjacent to the river are Zantedeschia aethiopica and Gomphocarpus fruticosus. These species are ‘Declared’ weeds under the Agriculture and Related Resources Act (1983) and found within the Environmental Weed Strategy for Western Australia.

Primarily there are two main methods for removing weeds and preventing invasion, these include: • Manual weeding, which is labour intensive; and • Using chemicals (herbicides) to eradicate weed species

There is growing community concern about the levels of residual chemicals present in the environment and as such manual removal of weeds will be maximised where possible within Precinct K, with chemicals used discretely when manual removal will not achieve weed control outcomes.

Table 6 below summarises the weed management and maintenance actions required.

5.4.3 Signage

It is envisaged that interpretive signage will be installed in various locations across Precinct K, but most notably at the Aboriginal heritage site DIA 26094 located in Park 9 and the Wungong River foreshore reserve.

Generally the themes included in the signage across Precinct K may include: • Identified archaeological sites and the history surrounding the area; • Reference boards for information, maps and identifiers at gateway locations; • History of the Amendment area; • Identifier signs for species and how ecological relationships work. These will need to be simple concepts; • Weed control and how the public can assist; • Water conservation and how Wungong is conserving water. This is particularly good for signs in toilets; • Fertiliser and the effects of using too much. This should also suggest how to reduce fertiliser use in gardens; • Illegal dumping of rubbish within the Foreshore Reserve and within the water bodies and how it will have an adverse effect on the conservation effort; and • Risk of Phytophtora Dieback and prevention of the pathogen.

Thorough plans submitted at subdivision stage will provide detail regarding proposed interpretive signage to be implemented.

5.4.4 Rehabilitation and Revegetation

The most significant areas of revegetation and rehabilitation will be along the Wungong River foreshore reserve. The majority of this area will be dedicated to the restoration of the riverine environment to a natural state. This reserve will be planted with species intended to produce a rich diversity of endemic plants, which are environmentally attractive, provide ecological functioning attributes and produce suitable fauna habitat.

The plant types to be used in the rehabilitation of the Wungong River fall into three form categories, namely sedges, shrubs and trees. The sedges will form the riparian zone and will be predominantly planted within the wetter areas. Shrubs and understorey plants will be situated mid way up the bank edges, in the slightly drier zones. Tree species will be located towards the upper slopes and across the dryland foreshore buffer area. It is anticipated that there will be variations in the species selected and with landscaping in some sections of the river foreshore.

The extent of revegetation will depend on the bank slope and the water flows. For example, emergent planting of sedges will be planted within differing distances from the low water mark of the Wungong River, depending on the height of the river, shallowness of the bank profile and the water requirements of the particular species. The Foreshore Management Plan (ENV 2007) includes a list of recommended species to use in

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

rehabilitation of the Wungong River foreshore area and these species are listed in Table 7 below.

Local provenance will be used to ensure the genetic integrity of this area is maintained. Root stock can be grown in local nurseries and transferred to the Wungong River foreshore as part of the restoration process. Plant taxa listed below (Table 7) will be collected from nearby local sites, germinated and then planted by experienced native revegetation contractors.

As a part of these plans, recommended planting densities in line with those of the City of Armadale Streamcare Kit include: • Trees: 20 plants per 100 square metres; • Embankment shrubs: 100 – 150 plants per 100 square metres; and • Watercourse beds and fringes: 400 plants per 100 square metres.

5.4.4.1 Monitoring and Evaluation

The purpose of vegetation monitoring is to provide information about the success of rehabilitation and revegetation within Precinct K and to adjust the way in which the rehabilitation is undertaken if the outcomes of the current methods are not satisfactory in returning natural biodiversity to the area.

Vegetation monitoring will involve setting up permanent monitoring quadrats within the foreshore and living streams in order to adequately sample the rehabilitation areas. From extensive revegetation work undertaken by ALCOA on bauxite mine rehabilitation they concluded that to provide adequate data on rehabilitation success, 3 to 5% of the total area

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

must be sampled. Less than 3% provides too little data, while over 5% provides too much (Grant and Koch 2006). Therefore monitoring quadrats will need to be set up within each management zone to cover approximately 4% of the total area within each management area. In addition to monitoring quadrats within the next stage, control-monitoring plots should be established within surrounding undisturbed/natural vegetation to provide a mechanism for comparison.

The quadrats should be established in autumn before rehabilitation work begins and the initial data recorded. The second round of monitoring should be undertaken in the spring of that year, followed by two more monitoring periods in the autumn and spring of the following year. The information gathered from the monitoring indicates the success of the current practices and the most successful methods of rehabilitation. Monitoring is required to determine if the completion criteria is fulfilled.

Monitoring quadrats should be established before rehabilitation works begin so initial baseline data can be recorded. The number of the monitoring quadrats within each management zone will be dependant on the area, but will need to cover 4% of the area to provide adequate data. All quadrats must be the same dimensions so that comparison between plots and across data can be made. 5 x 5m monitoring quadrats will be used where possible. Specific monitoring will include a visual inspection and a visual representation (e.g. photograph).

Once the quadrats have been established the following data should be recorded for each plot: • Quadrat Number; • Location; • Dimensions of the area; • Visual representation e.g. photograph, from a set point; • List of all vascular plants present; • Number of individuals of each native plant species; • Number of individuals of each exotic plant species; • After root stock have been planted, record species and number of root stock; and • After seed have been sown, record species and densities sown.

To determine the success of the monitoring, the following completion criteria should be achieved by the final spring monitoring period: • Root stock are healthy in appearance, diverse with no mass losses or species dominance; • The average seedling height has increased between assessments; • More than 75% of tube stock (from original and replacement plants) plants are alive; • Weed presence is minimal and not inhibiting native plant survival and growth; and • Wind break fencing is intact and functioning appropriately

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

These expectations are for a period of normal weather conditions and limited access to the site. Temporary signage will be erected around the rehabilitation and revegetation areas to alert the community of the rehabilitation works underway to ensure success.

As the area is highly disturbed and with weeds present, ongoing maintenance will need to address weed control, infill planting and the integrity of protection features such as windbreaks, fences and stakes to ensure success.

5.4.5 Enhancement of Ecological Corridors

The Precinct K LSP is consistent with the “Wungong Green Corridors” as outlined in the WUW Master Plan.

The Wungong River has been recognized as a key ecological corridor, home to a unique riverine and wetland system and has been reserved for conservation and revegetation, as outlined in Section 3.2.13 and 4.2. The Wungong River will serve as the key ecological corridor through Precinct K. Ecological linkages will also be strengthened through the established living stream and park avenues that are key areas for human movement, passive recreation, water management and the re-establishment of the riverine environment. In accordance with the Wungong Urban Water Master Plan Revised Draft Integrated Open Space and Landscape Policy, these green corridors will link ecological habitats, be coordinated to manage stormwater flow and link movement within the precinct.

Detailed plans will be submitted at subdivision stage clearly outlining revegetation works that will occur along the Wungong River foreshore reserve, the park avenues and the living streams to enhance these corridors.

5.4.6 Landscape Maintenance

The landscape maintenance strategy will evolve alongside those described above. The maintenance requirements of Precinct K will generally include the following for the landscaped areas and be in conjunction with the irrigation strategy outlined in Section 5.5: • Hand removal of weeds throughout garden beds and streetscapes; • Spraying of weeds in grassed POS and basins using appropriate herbicides; • Additional watering during plant establishment; • Replacement of failed plants; • Turf mowing and reseeding of bare/poorly established grass areas; • Spraying for control of insects; • Irrigation system surveillance • Cleaning of paved areas; and • Regular litter removal

Typically, the maintenance of POS areas is highly involved. It is anticipated that following the establishment of the garden beds, some degree of maintenance may be required to ensure that planted trees and shrubs survive. The turfed POS areas will require ongoing

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

maintenance and the extent of the turfed areas will be known closer to subdivision of areas within Precinct K when detailed plans are prepared. This maintenance includes:

• Ensuring turf areas are maintained to a standard that creates an aesthetically pleasing environment; • Providing a turfed area that will meet sporting and recreational requirements; • Ensuring the immediate and long-term health of the turfed areas; and • Controlling the spread of undesirable weeds and other pests that compete with turf.

Maintenance of streetscapes that will occur during initial establishment of the trees and groundcover may include the use of shelters for protection against wind, vehicles and vandals. As all trees and groundcover species have an expected growth habit, correct pruning and maintenance techniques in line with the species should be employed on an ongoing basis. Tree pruning is primarily to be undertaken for the following reasons:

• Formative pruning during initial planting stages; • Removal or limbs that constitute a physical or visual obstruction; and • Removal of invasive or destructive roots.

If a tree should become a safety or functional obstruction, or diseased removal may be required.

Maintenance of areas planted with native species will be ongoing, but restricted to servicing drainage and storm water infrastructure, resurfacing paths and firebreaks, reducing flammable undergrowth and eradication of invasive weeds.

Below Table 8 outlines the ongoing landscape management and maintenance requirements.

5.5 Irrigation Management Strategy

The purpose of this irrigation strategy is to ensure that irrigation is applied to Precinct K in an effective and efficient manner so as to avoid run-off from excessive irrigation and maintain water balance.

The general principle adopted throughout Precinct K will be to reduce the amount of irrigated areas. Turf areas require a high level of irrigation and have therefore been minimised with an emphasis on restoring native vegetation throughout the Precinct, which

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

requires less irrigation and maintenance. Irrigation methods throughout Precinct K will include reduced areas of turf, avoidance of species which require extensive irrigation, and the design of systems for water use efficiency.

As noted in Section 3.2.7 an internal non-potable water reticulation system (3rd pipe system) is proposed to be constructed within the Master Plan area. This initiative is in its infancy within Western Australia and it is envisaged that the system will be firstly connected to localised groundwater sources. The development of this system will follow guidelines established by the Department of Water and the Department of Health. It is anticipated that there is capacity within the groundwater management area to facilitate some allocation of irrigation water for the proposed development. Each of these bores and associated infrastructure will be designed and specified to suit local conditions.

Irrigation, when necessary, shall aim to incorporate a number of water conservation strategies, which include: • Use of subsurface, drip and trickle water application methods; • Reduced areas under surface spray water application • Installation of adequate irrigation control systems to ensure water can be supplied selectively, within the development and seasonally; • Application of water-saving mulch; and • Use of drought tolerant turf species throughout turfed areas

5.5.1 Soil Management

A key consideration of any water conservation strategy is the types and characteristics of landscape soils. A soil’s physical properties, such as structure and organic content, are often the most significant in relation to water retention. Well-structured and permeable soils with high organic content will tend to provide the greatest capacity to store and release water for plant needs. As water-holding capacity increases, greater intervals between irrigation can occur and maximise use of rainfall (Hassell, 2007).

The following soil management measures will be adopted to ensure improvement of moisture retention of the soil:

• Test and establish soil infiltration rates for a range of the garden and turf areas to guide irrigation cycles; • Improve and maintain soil permeability by preventing and managing compaction; • Avoid planting species with high water requirements in areas of hydrophobicity; • Applying preventative and continuing programs of wetting agents to known areas of dryness over warmer months; • Continue to apply mulches to maintain organic content; and • Review and progressively replace irrigation sprays that exceed soil infiltration rates with more suitable sprinklers.

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

5.5.2 Turf Management

Precinct K typically experiences a Mediterranean climate, with sporadic rainfall throughout the irrigation season, meaning rainfall is of little value in displacing irrigation demand. As such within this development turfed areas have been minimized. An appropriate irrigation rate will involve a balance between supporting plant growth and minimizing excessive and unnecessary use of water where possible.

Generally, watering requirements of active areas of turf are greater than typical garden bed requirements due to the additional growth that occurs as a result of anthropogenic disturbances. Addition water deficit stresses such as the following can affect turf: • Interception of rainfall by tree canopies; • Competition with tree roots for available water; • Hydrophobic soil conditions; • Irrigation scheduling conflicts due to overlap of hydro-zones between areas of open turf and under tree plantings; • Excessive thatch levels which inhibit water penetration; • Soil compaction; and • Mown height of turf is too short for the environmental conditions.

These considerations will be taken into account when developing turfed areas and irrigating them. It is anticipated that during summer one watering period a week will be delivered to the grassed area by the non-potable water reticulation system, while no water will be required over winter.

At the initial installation and establishment of the turf, the area will need to be kept moist during the first 2-3 weeks.

5.5.3 Garden Bed Management

Throughout Precinct K it is recommended that the garden beds are designed to ensure that plants with similar water requirements are grouped within a common irrigation zone and scheduling regime.

As described previously, it is preferable that plant species selected for the garden beds exhibit some morphological and physiological adaptation to water deficits. This will assist in ensuring irrigation requirements are maintained at a minimal rate, promoting water conservation. As the species are to be native, one watering period during summer is anticipated to be enough, while during winter no watering period will occur.

Mulching of all garden beds is recommended, with mulch composition and timing of application to be appropriate for the plant species and soil characteristics. This forms an integral part of water conservation as mulch reduces evaporation losses, improves soil characteristic and decreases water losses from run-off.

Version 2 V8100-KMK80003.20--JDH.doc

PRECINCT K WUNGONG URBAN WATER MASTER PLAN LANDSCAPE AND IRRIGATION MANAGEMENT STRATEGY

In establishing and maintaining POS and associated areas, it is anticipated that variation in the irrigation regime will be required. To ensure the successful establishment of new plants, temporary irrigation will be required. However, it is advised that where possible, this additional water be applied by hand to avoid excessive irrigation of the whole garden bed. For established tree and shrub transplants, the manual watering may extend for a year or more.

5.5.4 Drainage Controls

As described in Section 3.2.6, drainage controls will involve water sensitive urban design principals. Stormwater will be directed to POS areas, living streams and park avenue swales/basins in order to minimise effects on downstream flow following storm events. A conventional piped network with ‘leaky’ side entry/gully pits will be employed to convey stormwater and will be designed to suit appropriate spread rates. Additional flows will be directed to the Wungong foreshore for retention, detention and overland flows. The temporary storage of stormwater within the centre of the POS can be expected to reduce the POS water requirements.

5.5.5 Irrigation Maintenance

The irrigation schedule should be based on recommendations of this management strategy; however some variation may be required to account for local conditions. Specific irrigation requirements will be based on site specific data acquired through monitoring of the landscaped areas and administered as needed.

To meet the water requirements of the planted areas and to account for seasonal variations in rainfall and water content, irrigation should be adjusted monthly. The cumulative volume of water pumped by the irrigation system will be recorded on a monthly basis for the first two years. A manipulation of a water meter attached to the irrigation system will account for this. A record will also be maintained detailing the frequency, times and rate of irrigation. Detailed landscape plans will be submitted at subdivision stage outlining specific irrigation design and management requirements.

Table 9 summarises the ongoing irrigation management and maintenance requirements associated with the details above.

5.6 Mitigation Strategies – Avoidance and Offsets

As outlined in the Flora and Vegetation Assessments, there was limited ecological value within Precinct K as very little remnant vegetation remains with the area historically cleared and grazed.

Any remnant vegetation within Precinct K has been attempted to be retained through strategic positioning of POS, in line with that proposed within the Master Plan and within the reservation of Wungong River as a conservation area.

Throughout the planning stage of Precinct K, there has been an emphasis on native revegetation. There will be significant revegetation of the Wungong River as well as the living stream and within park avenues.

Based on the existing condition of Precinct K and the future rehabilitation works (especially along the Wungong River), any vegetation lost during construction (dependant on fill levels), will be offset through planting and rehabilitation. On this basis it is thought that no further mitigation strategies will need to be implemented.

6. REPORTING

Individual landowners will be responsible for developing progress and compliance reports to be submitted to the ARA and the City of Armadale.

An initial compliance report should be submitted to the City of Armadale and the ARA after the completion of POS construction and subsequent landscaping. During the two-year developer maintanance period, a further four separate reports will be generated, one every six months over the two-year period. Therefore in total five reports will be submitted to the City of Armadale and the ARA.

The reports will outline how the developer/landowner has complied with the LIMS, specifically Section 5 and will be specific for each landholding. Aspects of the landscaping areas that should be reported on include the Wungong River foreshore reserve, living streams, park avenues, areas of POS and any additional areas subject to landscaping, such as road reserves.

Within the report the overall condition of the POS, landscaped areas and foreshore reserve will be monitored in line with the criteria described in Section 5.4.4.1. Monitoring will involve a visual assessment of the growth and maintanence of components (e.g. existing and planted vegetation, presence of rubbish, condition of new infrastructure and weed infestation). The report should indicate the condition of the POS, landscaping (growth and maintenance) and the basin and drainage system based on photographs taken from set points.

7. RESPONSIBILITIES

The Precinct K Wungong Urban Water Master Plan LIMS provides a framework that the individual developer can utilise to assist in establishing landscape and irrigation management methods that have been based upon site-specific investigations and are consistent with relevant State and Local Government policies. The responsibility for working within the framework established by the LIMS rests with the individual developers. It is anticipated that additional details for the management of the landscape and POS will be developed in consultation and consideration with relevant agencies, policies and documents.
