BIOPHYSICAL ASSESSMENT (EMERGE ASSOCIATES 2015C)

Biophysical Assessment of Blackadder Creek, Blackadder tributary and Woodbridge Creek (Emerge Associates 2015)

Prepared for Peet Stratton Pty Ltd and Joe Candeloro Doc No.: EP14-043(07)--014 | Revision: 1

ENVIRONMENTAL ASSESSMENT AND MANAGEMENT STRATEGY MIDVALE LOCAL STRUCTURE PLAN

Biophysical Assessment of Blackadder Creek and Woodbridge Creek

Background

Peet Stratton Pty Ltd (Peet) and Joe Candeloro are preparing a Local Structure Plan (LSP) for various lots on Farrall Road, Orchard Avenue and Morrison Road in the localities of Midvale and Stratton, within the City of Swan. This area is herein referred to as “the site”. The site is zoned “Urban” under the Metropolitan Region Scheme (MRS) and “Residential Development” under the City of Swan’s Local Planning Scheme (LPS) No. 17.

The Department of Water (DoW) “Hydrography” mapping shows three mapped surface water features within the site (DoW 2015): Blackadder Creek in the north of the site, a tributary drain line referred to herein as the “Blackadder tributary” in the centre of the site, and Woodbridge Creek in the south of the site. The locations of each of these mapped waterways are shown in Figure C1.

The Blackadder Creek runs through the north of the site, from developed urban areas east of the site through to Rural zoned land west of Roe Highway. The Blackadder tributary originates within the site, in an area of Bush Forever in the east, runs south of Blackadder Creek through the centre of the site and discharges to Blackadder Creek west of the site. Woodbridge Creek enters the site to the north of Morrison Road and east of Farrall Road. The creek meanders in a north westerly direction before leaving the site under Roe Highway to the west of the site.

Biophysical Assessment

Policy context

As part of understanding the environmental values and attributes associated with the site and to define an appropriate foreshore area for these waterways, a biophysical assessment was conducted for Blackadder Creek, the Blackadder tributary, and Woodbridge Creek. This assessment has been undertaken in accordance with the Department of Water (DoW) Operational policy 4.3: Identifying and establishing waterways foreshore areas (Operational Policy 4.3, DoW 2012) and the Water and Rivers Commission (WRC) Water Note 23: Determining foreshore reserves (WRC 2001).

Specifically, Operational Policy 4.3 outlines the process for identifying and managing foreshore areas, to ensure that foreshore areas will maintain or improve the environmental, social and economic values associated with waterways and adjoining lands.

The DoW has an expectation that an appropriate setback should be provided between a waterway and any land-use and development activities within or adjacent to a waterway, to protect the waterway, human infrastructure and the foreshore area. Broadly, the setback should be determined to avoid:

 Flooding risks to properties and infrastructure.  Risks to public health, or harm to social values such as visual amenity, recreation, heritage and sense of place.  Alteration of hydrological regimes, erosion, degradation of water quality and degradation of aquatic and riparian ecosystems.

ENVIRONMENTAL ASSESSMENT AND MANAGEMENT STRATEGY MIDVALE LOCAL STRUCTURE PLAN

The determination of an appropriate setback (foreshore area) is based on understanding the physical and biological features of a waterway, also described as biophysical criteria. Broadly, an understanding of these criteria will assist in defining an area of influence that is associated with a waterway, which will guide the determination of an appropriate foreshore area.

Emerge has undertaken the following investigations to support this assessment:

 Desktop assessment of the features and services of the waterway.  Two site assessments with Emerge Hydrology and Ecology personnel. Emerge personnel used a GPS device to track the mapped Blackadder tributary waterway to determine the presence of any defined channel or visible waterway attributes.

This assessment has highlighted that ecological values are limited across the site due to historic agricultural land clearing activities which have removed any riparian vegetation values associated with the Blackadder Creek. Additionally, due to historic and existing unauthorised vehicle access within the site, there are no features representing a natural waterway (i.e. no obvious waterway channel or floodplain area) associated with the mapped Blackadder tributary. Woodbridge Creek, while in degraded condition, still retains remnant ecological (riparian) and hydrological values.

Biophysical criteria assessment

The biophysical criteria considered for Blackadder Creek, the Blackadder tributary and Woodbridge Creek has been outlined in the following sections, along with a summary of the findings. Within this assessment, Blackadder Creek, Blackadder tributary and Woodbridge Creek have been considered separately for each biophysical criterion. This assessment has been based upon a review of available desktop and background information, plus detailed site visits conducted by Emerge Associates. The biophysical features of the waterways are also shown in Figure C2.

Topography, landform and soils

The site is generally flat. Available contours indicate that topography within the site ranges from approximately 15 metres Australian Height Datum (mAHD) in the west to 17 mAHD in the east. Elevation rises in the east of the site associated with the existing railway line interface, ranging between 22-24 mAHD. Detailed Light Detection and Ranging (LiDAR) data for the site shows a clear channel associated with Blackadder Creek and Woodbridge Creek, but no channel in the location of the mapped Blackadder tributary.

Environmental geology (surface soils) across the site has been mapped by the Geological Survey of Western Australia (Gozzard 1986). The site is largely comprised of pebbly silty sand overlying clay consistent with the Guildford Formation with a small portion in the east of the site comprising medium- grained yellow sands of the Yoganup Formation. This was confirmed in the geotechnical survey undertaken across the site (Douglas Partners 2014). The underlay of clay soils is indicative of the Multiple Use wetlands that cover the large majority of the site.

Based on the geotechnical investigations undertaken for the site (Douglas Partners 2014), there is no notable change in soil types in the area of the Blackadder tributary that would represent a waterway. Aerial photography and detailed LiDAR contours show a clear channel associated with the Blackadder Creek and Woodbridge Creek, while there is no evidence of a channel in the mapped location of the Blackadder tributary. Two separate site inspections undertaken by Emerge personnel found there to be no landform features (i.e. channel) representative of a waterway in the location of the Blackadder tributary, as shown in Plate C1 and Plate C2 below, compared to the clear channel present in Blackadder Creek (Plate C3 and Plate C4 below) and Woodbridge Creek (Plate C5 below).

ENVIRONMENTAL ASSESSMENT AND MANAGEMENT STRATEGY MIDVALE LOCAL STRUCTURE PLAN

Plate C5: Field photograph from the location of the Woodbridge Creek showing clearly defined waterway channel

Woodbridge Creek was found to have a distinct meandering waterway channel of approximately 2-4 metres deep, and is known to convey flows all year round. The banks of Woodbridge Creek show signs of significant erosion, presumably a result of the extensive historic disturbance within the site. Blackadder Creek also has a clearly defined waterway channel through the majority of the site, however it is shallow and currently only conveys a small amount of seasonal flow through the site. Historic disturbances within the site, particularly the removal of remnant/riparian vegetation and unauthorised vehicle access, have significantly impacted on the already shallow banks, resulting in the erosion of portions of the waterway channel.

Vegetation extent and condition

The majority of the site has been historically cleared and used for grazing purposes, therefore remnant vegetation coverage is limited across the site. Other than one small area of woodland in the east of the site that is in ‘Good’ condition and vegetation in the east associated with Bush Forever that is in ‘Excellent’ condition, any remnant vegetation across the remainder of the site is in ‘Completely Degraded’ to ‘Degraded’ condition.

Historic aerials show a complete lack of riparian vegetation associated with the Blackadder Creek and Blackadder tributary as far back as aerials are available (to 1953), with generally scattered vegetation visible across the area (as shown in Plate C6 to Plate C9 below), however since the majority of the site contains wetland areas, this vegetation cannot be seen to be specific to the waterways and, in the case of the Blackadder tributary, there is no distinct waterway channel with riparian vegetation.

Due to the lack of available historic evidence (historic aerials) showing the presence of riparian vegetation (at any point in time) associated with the Blackadder tributary, it is difficult to ascertain whether this is a natural waterway feature or a drainage flow path resulting from extensive farming

Historic aerials of the Woodbridge Creek show the continued presence of vegetation in varying densities and condition, generally following the alignment of the waterway since 1953 (earliest publically available aerial). The alignment of the vegetation suggests it is associated with Woodbridge Creek, and has been assessed as riparian vegetation which is made up of sparse woodland of

Hydrology

Groundwater levels within the site are generally shallow which, combined with the clayey soils, results in the seasonal inundation/water logging of areas within the site. This was confirmed through site observations by Emerge personnel and is shown in Plate C12 and Plate C13 below.

Water ponding on the ground surface observed during site visits was considered unrelated to the Blackadder tributary (i.e. evidence of a channel), rather a result of the high groundwater levels combined with the altered contours of the site from extensive vehicle access. There were no obvious channel flows in areas of surface water ponding or in areas mapped as part of the Blackadder tributary. Water was observed within the Woodbridge Creek waterway channel during a survey of the site by Emerge botanical personnel in October 2014 (as shown in Plate C11 above).

ENVIRONMENTAL ASSESSMENT AND MANAGEMENT STRATEGY MIDVALE LOCAL STRUCTURE PLAN

Based on DoW Hydrography mapping the Blackadder tributary is shown to originate within the Bush Forever Site in the east of the site, flowing in a westerly direction across Farrall Road and the site, through to ‘Rural’ zoned land west of the site. Based on site observations by Emerge personnel, there is no evidence of the mapped Blackadder tributary within the Bush Forever Site, nor are there any culverts to allow this feature to pass under Farrall Road.

Detailed flood modelling undertaken for the site (Emerge Associates 2015a) indicates that, for the majority of the Woodbridge Creek waterway, the 100 year flood flows are contained within the existing channel while a small area of the eastern portion of the waterway (east of Farrell Road) requires a flood conveyance corridor of 5 – 15 m beyond the current Woodbridge Creek waterway banks (Emerge Associates 2015a). Blackadder Creek in the north of the site will require a flood corridor of up to 30m in width to convey upstream flows and incorporate major runoff events (flood storage areas) from the development prior to discharge from the site.

Indigenous heritage

Based on a review of the Department of Aboriginal Affairs (DAA) ‘Aboriginal Heritage Inquiry System’ online database (DAA 2014), there is a registered Indigenous heritage site covering the site, generally associated with the waterways that traverse the site. The details of this registered heritage site are as follows: Site ID # 3720 Blackadder & Woodbridge Ck – Mythological.

Previous Section 18 approvals (pursuant to the Aboriginal Heritage Act 1972) over the site indicate that there are potential Indigenous heritage values specifically associated with those portions of the Blackadder Creek and Woodbridge Creek that occur within the site. It is not believed that these values extend to the Blackadder tributary. Indigenous heritage values will be addressed through future Section 18 approvals.

Surrounding proposed land uses

Land use zoning within the site, including the waterways, is currently ‘Urban’ under the MRS and ‘Residential Development’ under the City of Swan’s LPS No. 17, although the site is currently used for agricultural/grazing purposes. The proposed future urban development of the site will restrict current unauthorised vehicle access which is the major ongoing degrading factor within the site.

The future urban development has the potential to increase the export of pollutants into the waterways through stormwater runoff; however this will be managed through water sensitive design measures to be incorporated into the development.

Summary

The following section summarises the main points resulting from the biophysical assessment of the Blackadder Creek, Blackadder tributary and Woodbridge Creek:

 There is no riparian vegetation values associated with the Blackadder Creek and the Blackadder tributary, rather scattered wetland vegetation in ‘Completely Degraded’ to ‘Degraded’ condition in the general proximity of both waterways. The majority of the site contains wetland areas, and therefore this vegetation is likely to be associated with wetland soils and groundwater rather than riparian vegetation associated with the waterway. Riparian values associated with the Woodbridge Creek occur in the south of the site.  While hydrological values remain in the Blackadder Creek and Woodbridge Creek waterways (waterway flow and distinct channel), the historic removal of riparian vegetation from the Blackadder Creek and the ongoing disturbance within the site (grazing and unauthorised access)

has resulted in the removal of significant ecological values from Blackadder Creek, specifically floristic and/or fauna habitat corridor values. There are no remaining hydrological values associated with the mapped Blackadder tributary.  Emerge personnel used a GPS device to track the mapped Blackadder tributary waterway to determine the presence of any defined channel or visible waterway attributes. No clear channel associated with the Blackadder tributary was observed throughout this waterway assessment.  Extensive observations were recorded on site while tracking the mapped Blackadder tributary (from the DoW hydrography mapping). Water ponding on the ground surface was visible across the majority of the site as well as in the area of the mapped Blackadder tributary; however this is considered to be a result of high groundwater levels and altered ground contours from unauthorised vehicle access within the site. Vehicle tracks are clear in Plate C12 and Plate C13 above, with water ponding following the line of the vehicle tracks rather than a natural waterway channel.  No evidence of the Blackadder tributary was found within the Bush Forever Site in the east of the site (the mapped origin of the tributary).  Soils within the site do not differ in the area of Blackadder Creek, Woodbridge Creek, or the mapped Blackadder tributary.  Based on flood modelling undertaken by Emerge Associates, the flood conveyance function of Blackadder Creek can be incorporated into a 6-30 m wide flood corridor (incorporating the waterway channel and flood conveyance requirements).  Based on flood modelling undertaken by Emerge Associates, the flood conveyance function of Woodbridge Creek can, for the majority of the waterway, be entirely accommodated within its existing waterway channel. A small area of the eastern portion of the waterway (east of Farrell Road) will require a flood conveyance corridor of 5 – 15 m beyond the existing banks of Woodbridge Creek.

Conclusions

Based on the results of the desktop and site analysis of the waterway values within the site, this assessment concludes that:

 While hydrological values are retained by the Blackadder Creek, there are no ecological values remaining. Therefore the alteration or realignment of this waterway through the development process within the site will not result in the removal or degradation of riparian values where the flow and floodplain capacity are retained and managed.  Both hydrological and ecological values are retained by the Woodbridge Creek.  There is no waterway present in the area of the mapped Blackadder tributary. No natural channel is present in the area, nor is there any historic evidence of the waterway occurring naturally. Based on available information, there are no riparian vegetation values or specific soil changes in the area of the mapped Blackadder tributary that would represent a current or historic natural waterway. We conclude that either all natural values have been removed through historic disturbances associated with previous land uses, or that the waterway was incorrectly mapped.

Subsequent to these conclusions, we make the following recommendations:

 The Blackadder tributary does not require consideration in any future LSP design, as there are no hydrological or ecological values associated with this feature.

 Given the absence of ecological values within Blackadder Creek, there are no issues with realignment of the waterway to incorporate existing remnant vegetation into the proposed floodplain area.  Existing riparian vegetation associated with Woodbridge Creek is to be retained within an appropriate waterway buffer/foreshore area for conservation purposes.  Based on flood modelling undertaken by Emerge Associates, the flood conveyance function of Blackadder Creek can be accommodated within a 6-30 m wide flood corridor (incorporating the waterway channel and flood conveyance requirements). This area should be incorporated into public open space within the LSP, which should also seek to improve riparian values through revegetation.  Based on flood modelling undertaken by Emerge Associates, the flood conveyance function of Woodbridge Creek can, for the majority of the waterway, be entirely accommodated within its existing waterway channel. A small area of the eastern portion of the waterway (east of Farrell Road) will require a flood conveyance corridor of 5 – 15 m beyond the existing banks of Woodbridge Creek.  Adequate vertical separation will be required to any built form adjacent to the Blackadder Creek and Woodbridge Creek floodplain areas (recommended minimum 1.2 m above the maximum groundwater level).  A 20 m waterway buffer should be provided on each side of the Blackadder and Woodbridge Creeks to accommodate existing hydrological and ecological values. These buffer areas should be excluded from future urban development through the placement of public open space areas.

Based on the information summarised above, the biophysical criteria considered most relevant for determining the foreshore area for Blackadder Creek and Woodbridge Creek are:

 Extent of remnant riparian vegetation.  Surrounding land use.  Indigenous heritage.

The Biophysical Assessment undertaken for Blackadder Creek and Woodbridge Creek determined the foreshore area between the waterways and surrounding urban development in order to maintain their ecological and hydrological function. A 20 m waterway buffer on each side of the creekline for Blackadder Creek will provide a suitable allowance for conveyance of floodwater from upstream catchments and runoff events from the adjacent development, while allowing for the retention of any remnant vegetation in the vicinity of the waterway. A 20 m waterway buffer on each side of the creekline should also be applied to Woodbridge Creek to ensure that remnant riparian values are retained within the associated public open space. These waterway buffers should be applied to the LSP design within specified public open space areas, with the intention that these areas are excluded from urban development. This will provide sufficient protection for the physical and biological values of these waterways during the future urban development of the Midvale LSP.
