Executive Summary

Krikis Tayler Architects engaged TRACE Environmental on behalf of The Property Investors Alliance (PIA) to

undertake a Preliminary Site Investigation (PSI) for the property located at 42-66 Junction Road, Schofields,

NSW (the site). The PSI is required to determine if the historical land use/s have the potential to have

contaminated the subsurface at the site which could affect the proposed medium density residential

redevelopment. The PSI was completed in accordance with Schedule B2 of the National Environment

Protection (Assessment of Site Contamination) Measure, Amendment 2013 (NEPM).

Based on the findings of this PSI, the following is concluded:

The site has been used for low density residential land use purposes since at least 1955. Also, small

scale agricultural activities and horse rearing/riding has occurred on the site historically. The site was

developed in its current configuration between approximately 1970 and 1994;

The site land use is currently low density residential;

It is proposed to redevelop the site with approximately ten low-rise apartment buildings;

The results of the historic searches and site inspection undertaken did not indicate a high potential for

contaminating activities to have occurred at the site historically;

The site is located in a low sensitivity environmental setting based on the preliminary Conceptual Site

Model (CSM) developed, and nearby land uses;

The site is not located in an area of known acid sulphate soils; and

The BCC DCP 2014 - Schedule Two for the Riverstone Precinct indicates that the north-eastern and

south-western corners of the site may be located within a region of higher salinity soils. An overlay of

the information from the Department of Infrastructure Planning and Natural Resources: Salinity

Potential in Western Sydney (Map: 2002) onto current aerial photographs indicates the site is within

an area of moderate potential for saline soils. The BCC map does not indicate that the site is located

with an area of known aggressive saline soils.

Based on the results of the PSI, there is considered to be a low potential for contamination to have occurred

at the site as a result of the current and historic agricultural and residential land uses of the property, and the

site is considered suitable for the proposed medium density residential redevelopment. In view of this, a

Detailed Site Investigation (DSI) is not considered necessary prior to the proposed residential redevelopment

of the site.

In the event that soil is excavated and requires off-site disposal during redevelopment, the soil should be

tested and classified in accordance with NSW EPA guidelines prior to disposal. Any imported material

brought onto the site, to achieve construction levels or for landscaping purposes, must be validated as being

suitable for the proposed residential land use.

If site specific soil salinity information is required, a subsurface investigation should be completed with the

collection of soil samples for indications of salinity. This is typically undertaken as part of a Geotechnical

Investigation. If the data indicates highly saline and/or aggressive soils, the data should be reviewed by

appropriately qualified structural and geotechnical engineers to ensure the structural design of the proposed

development takes into account any potentially aggressive soils which may exist at the site. The design of

any building structural components should be completed in accordance with Australian Standard AS 2159-

2009 Piling: Design and Installation. This standard includes tables on exposure classification of soils and

groundwater based on their aggressiveness to concrete and steel.

1 Introduction

Krikis Tayler Architects engaged TRACE Environmental on behalf of The Property Investors Alliance (PIA) to

undertake a Preliminary Site Investigation (PSI) for the property located at 42-66 Junction Road, Schofields,

NSW (the site). The PSI is required to determine if the historical land use/s have the potential to have

contaminated the subsurface at the site which could affect the proposed medium density residential

redevelopment. The PSI was completed in accordance with Schedule B2 of the National Environment

Protection (Assessment of Site Contamination) Measure, Amendment 2013 (NEPM).

A Locality Plan is presented in Figure 1 showing the location of the site, and a Site Plan showing the site

and surrounding features is presented in Figure 2.

The specific objectives of the PSI were to:

Assess the site condition relative to present and historical land uses;

Identify any current or historical potentially contaminating activities;

If applicable, identify the potential types and nature of contamination;

If applicable, identify potential human and ecological receptors;

Develop a preliminary Conceptual Site Model (CSM) to identify potential risks to human health and/or

ecological receptors that could potentially affect the use of the site; and

Provide conclusions and recommendations regarding the suitability of the site for the proposed

redevelopment, and identify any further investigation for potential site contamination, if considered

warranted.

2 Scope of Works

The following scope of works were undertaken in order to meet the objectives described above:

Conduct database searches and review of historical information from the following sources;

Current and historical certificates of title;

Council records including current and previous planning certificates;

NSW EPA administered environment management and contaminated land registers;

State Government records including a Dangerous Goods License search;

Review of available historical aerial photographs; and

Registered groundwater bore database search for bores in the site vicinity, to determine the

local hydrogeology and groundwater utilisation.

Determine the local environmental sensitivity, including geological, hydrogeological and hydrological

information and identification of nearby sensitive receptors;

Conduct an inspection of the site to:

Identify potential sources of contamination, assess surrounding sensitive land uses, and

evaluate the general condition of the site in relation to potential contamination;




Identify known or suspected areas of potential concern (if any); and

Interview site personnel, if available, regarding previous site activities and features.

Develop an initial CSM of the site, outlining potential contamination sources, and exposure pathways

and receptors which may be impacted, and undertake a preliminary environmental risk assessment;

and

If required, assess the suitability of the site for the proposed land use, and outline any

recommendations for further investigation that may be warranted to assess for potential contamination

at the site based on the results of the PSI.

3.2 Site Description & Adjoining Land Uses

A site inspection was completed by TRACE Environmental personnel on 30 March 2015. Photographs taken

during the site visit are included in Appendix B. Details of the site, as observed during the inspection and

gathered from other sources detailed in this report, are outlined in Table 3-2 below.

Table 3-2 Site Description

Category Observation

Current Use and Users/Occupiers

The site is approximately 41,000m2

in area. The site land use is currently low density residential with three separate dwellings; one on each lot listed above.

Future Use and Users/Occupiers

It is proposed to re-develop the site for medium density residential land use, comprising approximately ten low-rise apartment buildings. The future users of the site include construction workers during redevelopment and the future residents occupying the residences.

Current Zoning and Permitted Uses

All three lots that comprise the site are currently zoned as R3: Medium Density Residential (Blacktown Local Environment Plan 1988 and NSW Government’s Blacktown City Council Growth Centre Precincts Development Control Plan 2010) according to the Section 149 Certificate. Residential land use is a permitted use on the site.

Site features The site is roughly square in shape and covers an area of approximately 41,000m2. There

are three separate low density residential dwellings at the site (Photographs 1 through 3). The residence at 42 Junction Road appears to be unoccupied currently. Access to each residence is provided by driveways off Junction Road. There are two bitumen driveways and one unsealed driveway to provide access to 66 Junction Road. A pool is located on the 42 Junction Road property but appears that it has not been used recently (Photograph 4). There are also two unused small, metal sheds located at 42 Junction Road (Photograph 5) A series of metal and wood fences are installed to separate the various lots that comprise the site (Photographs 6 and 7). The former stable is still present in the central portion of the site. It is constructed of sheet metal and the walls have been covered with graffiti (Photograph 8). Most of the site is open, vegetated land with some trees (Photograph 9).




Category Observation

Underground Services The site is serviced by above and below ground utilities, and service pits were noted during the site visit in the southeast corner of the site. TRACE Environmental conducted a Dial Before You Dig (DBYD) search on 20 May 2015 which shows the approximate locations of underground and above ground services on the site. The DBYD plans are included in Appendix C. The site is serviced by a reticulated water supply and municipal sewer system. Additionally, Telstra fibre optic, water mains and power lines run along Junction Road and Advance Street.

Chemicals, raw materials and intermediate products storage and use

Reportedly, no chemicals, raw materials or intermediate products are currently or historically stored or used on-site. No signs of underground storage tanks (USTs) were noted during the site visit. Dangerous Goods records for the site, obtained from WorkCover NSW, did not indicate any quantities of dangerous goods being stored at the site currently or in the past.

Waste generation and storage

No hazardous waste is currently generated or stored on-site. Typical domestic waste is temporarily stored in bins prior to off-site disposal.

Reported spills, chemical losses, discharges to land/water and/or incidents/accidents

A search of the NSW EPA Contaminated Land Record on 20 May 2015 returned no results for the site. There are no reports of spills or incidents at the site.

Contaminated Land Records

A search of the NSW EPA Contaminated Land Record on 20 May 2015 returned no results for the site.

Surface covering/ Vegetation

Most of the property is covered with landscaping/vegetation including turf, flower beds, grass and some trees.

Electrical transformers/power generation

No electrical transformers were noted on-site. The site is provided power via above ground services.

Topography and infilling The site and surrounds are relatively flat with a gentle slope toward the east across the site. Any importation of fill historically would likely be limited.

Surface drainage Surface water is expected to drain from the roof and via gutters and pipes to a municipal storm water conveyance system. Most of the stormwater would infiltrate into the ground or flow along the surface with the natural topography.

3.3 Surrounding Land Use

The site is located within a predominantly low density residential area. At the time of the inspection, the

surrounding land uses comprised:

North: Low density residential with additional low density residential beyond;

East: Junction Road with low density residential and uncleared and partially wooded land beyond;

South: Low density residential with Schofields Road beyond; and

West: Uncleared, partially wooded land with low density residential beyond.

3.4 Surface Water Bodies

The closest surface water body is Eastern Creek, which is located between 1 and 1.2km west, northwest and

southwest of the site. Eastern Creek appears to flow toward the north, and eventually discharges to the

Hawkesbury River located approximately 11.5km north of the site.

3.5 Geology & Hydrogeology

The Penrith 1:100,000 Geological Series Sheet 9035 (Ed 1) (Geological Survey of NSW, 1991) indicates that

the site is underlain shale, carbonaceous claystone, claystone, laminite, fine to medium grained lithic

sandstone and rare coal and tuff. Bedrock below the site is mapped as Wianamatta Group Bringelly shale of




the middle Triassic period in the Mesozoic Era. Consistent with the lithology of surrounding sites, a layer of

unconsolidated, weather bedrock (overburden) exists above the bedrock. The site specific lithologic/geologic

conditions are not known at this time.

Groundwater may be present within the pore spaces of the overburden material and/or in the underlying

bedrock. The site specific hydrogeological conditions are not known at this time. However, regional

groundwater likely flows to the east and south east toward Strangers Creek with localised gradients in

various directions.

3.6 Registered Groundwater Bore Search

A search of the NSW NRAtlas database conducted on 27 March 2015, identified 14 registered bores within

an approximate 1 km radius of the site. However, no further information was available about these bores on

the NRAtlas website. The closest bore to the site is located approximately 290m to the southeast. Given the

distance and direction to this bore and likely direction of regional groundwater flow, it is not considered a

potential receptor of groundwater leaving the site. The other bores are located at greater distances to the

south, northwest, southwest and northeast. Given the distance and direction to this bores, they are unlikely

potential receptors of groundwater leaving the site.

This Lot and DP were transferred to other various private individuals since 1949 presumably for continued low density residential use.

Copies of title documents are provided in Appendix D.

4.2 Historical Aerial Photograph Review

Aerial photographs of the site for the years 1956, 1970 and 1994 were sourced from the NSW Land and

Property Management Authority, a 2009 photograph was sourced from Google Earth, and a 2014

photograph was sourced from NSW Land and Property Six Maps viewer. A summary of the photographs is

provided in Table 4-4, below. Aerial photograph extract images are presented in Appendix E.

Table 4-4 Summary of Historical Aerial Photographs

Aerial Photograph Description

1956 Black and White

The site appears cleared of some native vegetation but there are trees present in the central portion of the site. A low density residential dwelling is noted at the eastern boundary of the site. Most of the site appears unused/open vegetation but there are gardens and/or small orchid noted in the northern portion of the site. Surrounding areas are also cleared of native vegetation with some trees remaining and appear to be used for residential and/or farming/agricultural purposes.

1970 Black and White

The site development is consistent with the 1955 aerial photograph but there is an additional residence located in the northwest corner of the property. The gardens/orchids are no longer present on the site. The vicinity land use is consistent with the 1955 photograph with increased low density residential land use noted to the northwest.

1994 Colour

The site has been developed since the 1970 aerial photograph and is consistent with the current configuration. The site includes three low density residential dwellings and what appears to be a large shed or stable. A track is apparent in the western portion of the site which may be used for horse riding. Most of the site is cleared of vegetation but some trees are still present around the site. The vicinity land use is consistent with the 1970 aerial photograph with increased low density residential development noted in all directions.

2009 Colour

The site and vicinity development is consistent with the 1994 aerial photograph, except there is increased low density residential development noted.

2014 (Figure 2) Colour

The site and vicinity development is consistent with the 2009 aerial photograph.




4.3 Contaminated Land Record Review

The NSW EPA environmental register for contaminated land records was accessed online on 20 May 2015

(http://www.epa.nsw.gov.au/prclmapp/sitedetails.aspx). No notices or declarations were listed for the site. A

copy of the search results is included in Appendix F.

4.4 Relevant Planning Information

The planning certificates, issued under Section 149(2) of the Environmental Planning and Assessment Act,

1979, was obtained from Blacktown City Council for each Lot and DP comprising the site. A review of the

Section 149 Planning Certificates indicates the following for all three Lots and DPs:

Land Use Zone – R3 Medium Density (Residential Blacktown Local Environment Plan 1988 and NSW

Government’s Blacktown City Council Growth Centre Precincts Development Control Plan 2010);

The site does not include critical habitat;

The site is not located within a conservation area;

An item of environmental heritage is not listed as being situated on the land;

The land is not affected by the operation of sections 38 or 39 of the Coastal Protection Act 1979, to

the extent that council has been so notified by the Department of Services, Technology and

Administration;

The land is not proclaimed to be a mine subsidence district within the meaning of section 15 of the

Mine Subsidence Compensation Action 1961;

The site is not shown as being subject to tidal inundation;

The site is not shown as being subject to subsidence;

The site is not shown as being subject to flood related development controls;

The site is not within a known acid sulfate soil area; and

Matters arising under the Contaminated Land Management Act, 1997 – Not applicable.

A review of the s149s indicates that the site has not been identified as significantly contaminated. A copy of

the planning certificates are provided in Appendix G.

4.5 Acid Sulphate Soil

A review of the NSW Department of Land and Water Conservation Acid Sulfate Soil Risk Maps shows the

site to be located outside of areas of known Acid Sulfate Soil (ASS). In addition, a review of the maps

provided online by the Australian Soil Resource Information System (ASRIS) shows the site to have a low

probability of occurrence for ASS.

http://www.epa.nsw.gov.au/prclmapp/sitedetails.aspx




4.6 Saline Soils

Saline soils are produced when salts stored in the soil profile are mobilised by the movement of water

through evaporation or accumulation. These processes can cause an increase in salt levels to the extent that

vegetation and building materials such as concrete and steel are affected. Highly saline soils can be

aggressive to building foundations and/or preclude the establishment of some types of vegetation. Therefore,

it is important to determine the potential of saline soils at a re-development site.

The BCC DCP 2014 - Schedule Two for the Riverstone Precinct indicates that the north-eastern and south-

western corners of the site may be within an area of potentially higher salinity soils. An overlay of the

information from the Department of Infrastructure Planning and Natural Resources: Salinity Potential in

Western Sydney (Map: 2002) onto current aerial photographs indicates the site is within an area of moderate

potential for saline soils. The BCC map does not indicate that the site is located with an area of known

aggressive saline soils.









4.7 Dangerous Goods Search

A search of the Stored Chemical Information Data Base (SCID) and the microfiche records held by

WorkCover NSW for the site was requested on 5 May 2015. A search of the SCID and the microfiche

records held by WorkCover NSW has not located any records pertaining to the site. The results of the

dangerous goods search are provided in Appendix H.

4.8 Historical Environmental Investigations

TRACE Environmental is not aware of any previous environmental investigations that have been conducted

at the site.




5 Initial Conceptual Site Model

The environmental risk assessment is based on a contaminant (source) - exposure pathway - receptor

methodology. This relationship allows an assessment of potential environmental risk to be determined, in

accordance with the current national guidelines. Central to the requirements for the assessment of risk is the

development of an initial conceptual site model (CSM), identifying each contaminant source and the

associated receptor exposures.

Generally, a CSM provides an assessment of the fate and transport of contaminants of potential concern

(COPCs) relative to site-specific subsurface conditions with regard to their of potential risk to human health

and the environment. The CSM takes into account site specific factors including:

Sources of potential subsurface impacts;

Identification of potential COPCs derived from the possible sources identified;

Vertical and lateral distribution of potential COPCs;

Site specific lithologic information including soil type(s), depth to groundwater, effective porosity, and

groundwater flow velocity; and

Actual or potential receptors focusing on future and current land use both of the site and adjacent

properties and sensitive ecological receptors.

Based on the information sourced in this PSI, a preliminary CSM has been developed and is outlined in

Table 5-1, below. Additional details are included in the sections that follow as necessary.

Table 5-1: Preliminary Conceptual Site Model

Conceptual Site Model Element

Description

Site History/Contaminant Sources

According to historical information, the site was cleared of natural vegetation and utilised for low density residential purposes as early 1949 and likely earlier. It appears that small scale agriculture use occurred on-site from 1955 to sometime before 1970. Based on the aerial photographs and historical titles, it appears the site has been used for low density residential land use since at least 1949 to the present. The results of this PSI do not indicate any significant potential sources of subsurface impacts resulting from historical land uses.

Site Current and Future Use The site is currently occupied and used primarily for low residential land use. It is proposed to redevelop the site for medium density residential land use.

Site Geology Site specific geological information is not known at this time. According to geological maps, the site is underlain by shale and sandstone. Consistent with the lithology of surrounding sites, a layer of unconsolidated, weather bedrock (overburden) likely exists above the bedrock. The thickness of the overburden and the depth to the bedrock at the site is unknown.

Site Hydrogeology Groundwater may be present within the pore spaces of the overburden material and/or in the underlying bedrock. The site specific hydrogeological conditions are not known at this time. However, regional groundwater likely flows to the west toward Eastern Creek with localised gradients in various directions.

COPCs – Soil There are no known historical releases, or evidence of any significant potential sources of subsurface impact identified. Therefore, no COPCs have been identified for soil.

COPCs – Groundwater There are no known historical releases, or evidence of any significant potential sources of subsurface impact identified. Therefore, no COPCs have been identified for groundwater.

Adjacent Residents (dermal exposure, inhalation, ingestion). Future potential human receptors include:

Construction Workers (dermal exposure, inhalation, ingestion);

Site Residents (dermal exposure, inhalation, ingestion); and

Adjacent Residents (dermal exposure, inhalation, ingestion).

Potential Environmental Receptors

Eastern Creek is located between 1 and 1.2km west, northwest and southwest of the site. Eastern Creek appears to flow toward the north, and eventually discharges to the Hawkesbury River located approximately 11.5km north of the site.

5.1 Preliminary CSM Summary and Risk Assessment

Historical information indicates the site was cleared prior to the 1950s and was utilised for low density

residential land use, small scale agriculture and potentially horse rearing/riding since at least 1949. The

results of the PSI did not indicate any significant potential sources of sub-surface impacts resulting from the

historic land uses. The overall environmental sensitivity and risk at the site is deemed low based on the

preliminary CSM. No evidence of any significant importation of fill material was identified at the site.

Regardless, any soil requiring removal from the site for development purposes should be classified in

accordance with the NSW EPA Waste Classification Guidelines. Any soil imported to the site for construction

and/or landscaping purposes should be validated as suitable for the proposed land use.

5.2 Data Gaps and Uncertainties

No significant data gaps have been identified that impact the conclusions or recommendations of this PSI.




6 Conclusions and Recommendations

6.1 Conclusions

Based on the findings of this PSI, the following is concluded:

The site has been used for low density residential land use purposes since at least 1955. Also, small

scale agricultural activities and horse rearing/riding has occurred on the site historically. The site was

developed in its current configuration between approximately 1970 and 1994;

The site land use is currently low density residential;

It is proposed to redevelop the site with approximately ten low-rise apartment buildings;

The results of the historic searches and site inspection undertaken did not indicate a high potential for

contaminating activities to have occurred at the site historically;

The site is located in a low sensitivity environmental setting based on the preliminary Conceptual Site

Model (CSM) developed, and nearby land uses;

The site is not located in an area of known acid sulphate soils; and

The BCC DCP 2014 - Schedule Two for the Riverstone Precinct indicates that the north-eastern and

south-western corners of the site may be located within a region of higher salinity soils. An overlay of

the information from the Department of Infrastructure Planning and Natural Resources: Salinity

Potential in Western Sydney (Map: 2002) onto current aerial photographs indicates the site is within

an area of moderate potential for saline soils. The BCC map does not indicate that the site is located

with an area of known aggressive saline soils.

6.2 Recommendations

Based on the results of the PSI, there is considered to be a low potential for contamination to have occurred

at the site as a result of the current and historic agricultural and residential land uses of the property, and the

site is considered suitable for the proposed medium density residential redevelopment. In view of this, a

Detailed Site Investigation (DSI) is not considered necessary prior to the proposed residential redevelopment

of the site.
