1. BACKGROUND
1.1. Introduction
City Plan Heritage (CPH) has been engaged by the applicant to prepare the following Heritage Impact Statement (HIS) to accompany a State Significant Development Application (SSDA) for the subject site at Lot 9001/ DP 1206596 in East Leppington. The project relates to the proposed construction of a new public primary school to accommodate approximately 1,0121,000 students. The primary school will include 44 classrooms, a new multi-purpose hall for East Leppington, administration/staff centre, library resource centre, amenities and storage, staff car parking and site services. The proposed development is aimed to meet the education needs of the increasing population of East Leppington, a suburb experiencing urban and population growth. The proposed location for the primary school is consistent with the East Leppington 'indicative layout plan'1 and will provide a new school that is easily accessible for the primary school aged population anticipated within the Precinct. The proposed development has been constituted as State Significant Development (SSD 9476) in accordance with Division 4.7 of the Environmental Planning and Assessment Act 1979. In accordance with the relevant controls regarding heritage contained in the Campbelltown City Centre Growth Centre Precincts Development Control Plan (DCP) 2016 and the Growth Centres State Environmental Planning Policy (SEPP) 2006 will apply to the proposed development. This Heritage Impact Statement (HIS) assesses the likely impacts the works may have on the relative heritage values of the subject site and the heritage items in its proximity. All recommendations are made in accordance with statutory requirements and cultural heritage best practice. This HIS addresses the concept design phase only. City Plan Heritage (CPH) was not involved in the concept design process.
1.2. The Site
The subject site is located on the north-west side of Commissioners Drive, bordered by Willowdale Drive to the north-east, and Elkhorn Street to the south-west. The site also has a frontage to the heritage listed 'Upper Canal' to the north-west. East Leppington is approximately 39km south-west of the Sydney Central Business District (CBD). For a more detailed description of the site and its context, see Schedule 2.

Research for this HIS has adopted a two-stepped approach. Step 1 involving a desktop assessment and Step 2 being a site survey. This document provides the findings and recommendations resulting from this approach. Step 1 Research into the early development of the site was undertaken to get a better understanding of the place. In addition, the Aboriginal Heritage Information Management System (AHIMS) was searched to establish the location and background information on any Aboriginal objects or Aboriginal Places that are known to have special significance with respect to Aboriginal culture. Further, the SEPP 2006 and the NSW State Heritage Register were examined to determine the known heritage values of the subject site. Step 2 An onsite survey of the subject site and the context of its setting within Catherine Field was conducted by Samara Allen and Brittany Allen on 14 November 2018 with the purpose of photographing and understanding the place. All results are presented in Schedule 2 - Site Context and Description.

2. SITE CONTEXT AND DESCRIPTION
2.1. Site Context
The subject site is located in the new suburb of East Leppington to the south of Willowdale Drive, west of Commissioner Drive, and to the north of Elkhorn Street. East Leppington is an up and coming predominately residential suburb, and Willowdale Drive, Commissioner Drive and Elkhorn Street feature residential properties. The site was previously known as Dogwood Park (Google Maps) and is approximately 2.97km south-east of the Leppington train station. East Leppington is approximately 39km south-west of the Sydney Central Business District (CBD). To the north and east of the subject site the suburb is as yet undeveloped with a mixture of uncleared and cleared land. To the west of the subject site is the 'Upper Canal System (Pheasants Nest Weir to Prospect Reservoir)' (SHR no. 01373) listed heritage item (see Figure 3). The Canal is bordered on both sides by wrought iron fencing. The overall context of the local area is described as follows in the East Leppington Precinct Masterplan by LFA.2 Much of the Precinct is in single ownership and rural use and incorporates lands associated with the Campbelltown ‘Scenic Hills’ and remnants of the 1840’s Leppington House with its cultural heritage landscape. The following images provide an overview of the site's current context.

2.2. Site Context
The subject site is comprised of an undeveloped lot bordered by up and coming residential streets. The site is of a trapezoidal shape with an approximate area of 2.779 hectares. The subject site has previously been cleared and features a surface of compact red clay, tufts of grass and weeds. The surface is uneven, cracked and dry with evidence of litter, scattered rock and soil erosion (Figure 21, Figure 22 and Figure 23). Topography within the subject site is relatively flat, declining towards the canal in a gradual slope. The north of the subject site adjacent to the Upper Canal features a fenced-off portion of floodway approximately 30m wide x 175m in length. This floodway zone is denotated by signage and separated from the rest of the subject site with post and wire fencing (Figure 24). Grass and weeds in the floodway are overgrown, with a greater portion of vegetation than the rest of the site in comparison (Figure 24).

3. HISTORICAL OVERVIEW
3.1. Brief Suburb History
A detailed history of the Upper Canal System has been included in Appendix A.
3.2. History of the Subject Site
Prior to European arrival, the location of the subject site was land occupied and utilised by the Muringong people of the Dharug language group.3 The subject site was part of the 'Leppington Park' Estate officially granted to William Cordeaux in 1821, though some reports suggest he resided in the area earlier.4 Cordeaux had arrived in Australia onboard the convict transport ship Friendship and was appointed to the Commissariat Department of NSW in May 1817. Cordeaux took charge of the commissariat at Liverpool from 1821 and constructed a large house between 1823 - 1828 which he named Leppington House (Figure 26).5 Leppington House stood north of the subject site with a frontage to Denham Court Road (Figure 28). Leppington House was a large, two-storey dwelling complete with a ballroom, constructed by convict labour and known to have over 30 employees, 24 of them convicts.6 The Cordeaux family raised sheep and cattle on their land, the largest capacity in the district of the time.7 After Cordeaux passed away in 1839 at Leppington, his widow let the Leppington property to James Payten in the early 1870s and moved away.8 The Paytens continued to farm at Leppington until 1873 prior to relocating to the Woodbine estate. Following occupation by the Paytens, records show that Leppington was under the ownership of representatives of H. Bell into the 1890s and Charles Perry by 1906. Perry and his wife established a country tea garden at the homestead complete with a riding school which allowed visitors to hire horses and ride throughout the property. Perry also had a collection of various aviaries, kangaroos, wallabies and monkeys he kept on the land of the estate.9 During the 1880s part of the Leppington estate was resumed by the Public Works Department of NSW for the construction of the Upper Canal as part of the Upper Nepean Scheme (as seen in Figure 28). The area surrounding the Upper Canal and subsequently the subject site was described as very rugged and isolated country at the time of resumption.10 Leppington House fell into disrepair and later burnt down in the 1940s with some of its bricks re-purposed at Leppington Public School, which was established north-west of the subject site in 1923 as 'Raby Public

School'.11 The suburb surrounding the Leppington Public School and Post Office, established in 1924, later adopted the name of Leppington despite not having existed within the confines of Cordeaux's land grant.12 After Leppington House burnt down, the lands comprising Cordeaux's grant, including the subject site, were utilised by the army for target practice, scout camping grounds and for horse riding grounds.13 The subject site is currently denoted within the suburb of Denham Court according to Google Maps, but forms part of the East Leppington Development Precinct since its rezoning in 2013.14 Denham Court was named after Captain Richard Brooks' estate of the same name, though this was not the elected suburb name until the 1970s.15 The Denham Court estate was directly to the north of the Leppington estate and was subdivided into 444 blocks by Andrew Blomfield in 1884 (Figure 28).16 In the 20th century Denham Court developed with larger mansion housing dotted throughout, though areas to the south now encompassing 'East Leppington' have largely remained undeveloped. The subject site has most recently briefly been utilised as the Dogwood off-leash dog park which opened to the community in October 2017.17 Table 1 provides a summary of the history of the site.

4. ASSESSMENT OF SIGNIFICANCE
4.1. Understanding Heritage Significance
Each place is unique and has its own combination of values. Therefore, before making decisions about the future of a heritage item it is essential to understand its heritage values so that these will be retained when making future decisions about the place. The statement of heritage significance summarises an item’s heritage values. The following assessment of significance has been prepared in accordance with the ‘Assessing Heritage Significance’ guidelines from the NSW Heritage Manual. a) an item is important in the course, or pattern, of the local area’s cultural or natural history The subject site is within close proximity to the Upper Canal built as part of the Upper Nepean Scheme, and was originally part of the Leppington estate granted to William Cordeaux. The subject site has been greatly disturbed in the following years and is not deemed important in the course of the historical context of the surrounding landscape. It does however hold some significance as it reflects the subdivision pattern of the Leppington estate and the recent boom in residential development in the greater Sydney Metropolitan area. b) an item has strong or special associations with the life or works of a person, or group of persons, of importance in the local area’s cultural or natural history The subject site was part of the land of the Leppington estate and can be associated with the life of William Cordeaux but this is not a primary significance in terms of historical associations. c) an item is important in demonstrating aesthetic characteristics and/or a high degree of creative or technical achievement in the local area The subject site does not demonstrate important aesthetic characteristics of a high degree of creative or technical achievement in the local area. The subject site is a vacant lot with no built or landscape features of note. d) an item has strong or special association with a particular community or cultural group in the local area for social, cultural or spiritual reasons Historical research to date has not identified a strong or special association between the subject site and a particular community or social group for social, cultural or spiritual reasons. e) an item has potential to yield information that will contribute to an understanding of the local area’s cultural or natural history Historical research to date does not suggest that the subject site has the potential to yield information that will contribute to an understanding of the local area's cultural or natural history. f) an item possesses uncommon, rare or endangered aspects of the local area’s cultural or natural history The subject site does not feature any items possessing uncommon, rare or endangered aspects of the local area's cultural or natural history. g) an item is important in demonstrating the principal characteristics of a class of the local area’s cultural or natural places; or cultural or natural environments

Heritage Impact Statement Proposed East Leppington School Commissioners Drive, Denham Court NSW 2565 Project # H-19069 September 2019
The subject site does not consist of features important in demonstrating the principal characteristics of a class of the local area's cultural or natural places, or cultural or natural environments. However, it does reflect subdivision of the Leppington Estate and the more recent residential development.
4.2. Statements of Significance
4.2.1. The Subject Site
The subject site is not identified as having any cultural heritage value that would warrant its listing on a statutory heritage register. It is encompassed within the Camden area, traditionally lands occupied by the Muringong people of the Dharug language group. In 1821 2000 acres of land were granted to William Cordeaux as the 'Leppington'. The subject site has been associated with horse riding lands, army target practice, scout training, and most recently an off-leash dog park.
4.2.2. The Upper Canal
The following statement of significance has been extracted from the State Heritage Register (SHR) form compiled for this State heritage item, 'Upper Canal System (Pheasants Nest Weir to Prospect Reservoir)' (SHR no. 01373).18 The Upper Canal System is significant as a major component of the Upper Nepean Scheme. As an element of this Scheme, the Canal has functioned as part of Sydney's main water supply system since 1888. Apart from maintenance and other improvements, the Upper Canal has changed little. As part of this System, the Canal is associated with Edward Moriarty, Head of the Harbours and Rivers Branch of the NSW Public Works Department. The Canal is aesthetically significant, running in a serpentine route through a rural bushland setting as an impressive landscape element with sandstone and concrete-lined edges; The Canal is significant as it demonstrates the techniques of canal building, and evidence of engineering practice. The Canal as a whole is an excellent example of 19th century hydraulic engineering, including the use of gravity to feed water along the canal… The Upper Nepean Scheme is significant because: * In its scope and execution, it is a unique and excellent example of the ingenuity of late 19th century hydraulic engineering in Australia, in particular for its design as a gravity-fed water supply system. * It has functioned as a unique part of the main water supply system for Sydney for over 100 years and has changed little in its basic principles since the day it was completed. * It represented the major engineering advance from depending on local water sources to harvesting water in upland catchment areas, storing it in major dams and transporting it the city by means of major canals and pipelines. * It provides detailed and varied evidence of the engineering construction techniques prior to the revolution inspired by reinforced concrete construction, of the evolution of these techniques (such as

the replacement of timber flumes with wrought iron and then concrete flumes), and of the early use of concrete for many engineering purposes in the system. * The scheme possesses many elements of infrastructure which are of world and national renown in technological and engineering terms. * Many of the structural elements are unique to the Upper Nepean Scheme.

The construction of a multi-storey teaching/administration building within the subject site will allow for the potential new views of the Upper Canal heritage item previously unavailable due to the surrounding topography. The scale of the proposed building is not, however, considered to be of any adverse impact for the heritage item's setting, which is in the process of being dramatically changing. In accordance with this clause, this HIS has given careful consideration to the proposed works and their impact on the significance of the heritage item located in proximity. A detailed impact assessment has additionally been provided under the controls for the Campbelltown City Council Growth Centre Precincts Development Control Plan (DCP) 2016 discussed in Section 5.2 above.

5.4. Upper Canal, Pheasant's Nest to Prospect Reservoir, Conservation Management Plan (CMP) 2004
The section below addresses the 2004 CMP compiled by Higginbotham and Associates. The CMP classes the subject site as within the 'Ingleburn Dam; sluice gates; former cottage site - Section 7' addressed in Section 2.7 of Volume 1. The CMP states the following: 2.7 Ingleburn Dam; sluice gates; former cottage site - Section 7 2.7.1 Description: Between Raby and St Andrews Roads (near the extant colonial homesteads Raby to the west and Varrovile to the east along St Andrews Road) are two remnant groups of plantings relating to the Ingleburn Dam. To the West of the dam along the ridge is a group of Monterey Pines while to the north of the dam there is another former cottage site with remnant plantings of two further pines and several Coral Trees ((Erythrina x sykesii). As with the gully landscape noted under the previous item (2.6) and the following for the Liverpool Offtake Reservoir (Item 2.10), the present site contains an extensive area of native grassland featuring Kangaroo Grass and represents a valuable ecological resource. 2.7.2 Physical Condition: Generally good. 2.7.3 Integrity/intactness: In the case of both the former cottage group and the ridgeline pines the existing trees are likely the surviving remnant of more numerous plantings and are therefore only partially intact. 2.7.4 Significance:
Page | 44
Heritage Impact Statement Proposed East Leppington School Commissioners Drive, Denham Court NSW 2565 Project # H-19069 September 2019
The extant plantings of Monterey Pine and Coral Tree further reinforce the importance of the Upper Canal corridor as a major public utility development. The surrounding native grassland area represents something of the indigenous flora prior to European occupation and currently provides an important habitat resource and useful ground cover. 2.7.5 Conservation Management Recommendations: - Conserve the remnant tree groups. - Reinforce the pine group along the ridge to the west of the dam - preferably on the basis of further research. - Manage the surrounding area as indigenous grasslands ensuring appropriate maintenance techniques to enhance its ecological values…

As the proposed development does not involve any works to the heritage item, an updated CMP has not been prepared. The existing 2004 CMP compiled by Higginbotham and Associates has been considered in detail in Section 5.4. Some interpretation of the Upper Canal heritage item has been identified in the concept design for the proposed works for inclusion onsite. This will consist of a winding brick and sandstone path to represent the history and significance of the Upper Canal. Further specific detail regarding the interpretive design has yet to be established.
5.6. 'Statements of Heritage Impact' (NSW Heritage Manual)
The following table addresses the proposal in relation to relevant ‘questions to be answered’ in the NSW Heritage Manual ‘Statements of Heritage Impact’ guidelines relating to a new development adjacent to a heritage item (including additional buildings and dual occupancies).
Questions to be answered This proposal relates to these matters as follows:

The subject site is located within an upcoming suburban area, surrounded by residential development on either side of the Upper Canal heritage item.

6. CONCLUSION AND RECOMMENDATIONS
In conclusion, it is considered by City Plan Heritage that the proposed development, including construction of a new public primary school with 44 classrooms, a joint-use for a new multi-purpose hall for East Leppington, administration/staff centre, library resource centre, amenities and storage, staff car parking and site services will result in a negligible impact to the heritage significance of the nearby heritage item. The new school proposed for development will be set back from the Upper Canal heritage item and separated from it by the tall wrought iron fence which has previously been installed on either side of the canal. This separation will minimise physical access to the heritage item. Views toward the heritage item will be positively increased; in its current condition the heritage item has little visibility from the subject site due to the topography of the site and that the canal is at a lower elevation. In addition, the tall wrought iron fencing obscures the canal from ground level. The proposed development will increase the potential for views of the canal from the upper storeys of the new structures, which were previously unavailable. Views from the heritage item, due to the lowered elevation of the canal, will remain primarily unaffected. Overall the proposed development will have a positive to neutral effect on the adjacent section of the Upper Canal. Historical and cultural archaeological values of the site are currently being assessed by Biosis Pty Ltd and will be considered when their findings are known. The proposal demonstrates compliance with the existing controls regarding heritage conservation and is therefore recommended to Council for approval.

APPENDIX A The following history has been extracted from the State Heritage Inventory (SHI) form compiled for the site of 'Upper Canal System (Pheasants Nest Weir to Prospect Reservoir)' (SHR no. 01373).20 Upper Canal System: By 1869 it was recommended that construction commence on the Upper Nepean Scheme. This consisted of two diversion weirs, located at Pheasant's Nest and Broughton's Pass, in the Upper Nepean River catchment, with water feeding into a series of tunnels, canals and aqueducts known as the Upper Canal. It was intended that water be fed by gravity from the catchment into a reservoir at Prospect. This scheme was to be Sydney's fourth water supply system, following the Tank Stream, Busby's Bore and the Botany (Lachlan) Swamps. Designed and constructed by the Public Works Department of NSW, Prospect Reservoir was built during the 1880s and completed in 1888. Credit for the Upper Nepean Scheme is largely given to Edward Orpen Moriarty, the Engineer in Chief of the Harbours and Rivers Branch of the Public Works Department from 1858-88. The Upper Canal System is an integral element of the Upper Nepean Scheme which collects water from the four major dams on Cataract, Cordeaux, Nepean and Avon Rivers. The 64km long Upper Canal is the man-made section of the Scheme between Pheasant's Nest Weir and Prospect Reservoir and still operates as a gravity supply. The Scheme delivered its first water in January 1886 and functioned until…the Upper Nepean Scheme was fully-commissioned into use in 1888, along with Prospect Reservoir. The Canal was built using a variety of materials and structure types to suit the nature of the countryside through which it was passing. Above ground the water was channelled in open canal sections. Where the ground was soft the Canal was V-shaped and lined with shale or sandstone. In other sections, it was U-shaped and lined with sandstone masonry or left unlined where the Canal cut through solid rock. Where the water had to pass through hills or rises, tunnels were excavated and left unlined where they passed through rock and lined with brick where they cut through softer material. Over creeks and other deep depressions, the water moved through wrought iron aqueducts. Other original design features included: stop boards to allow sections of the Canal to be closed for cleaning and repair; flumes to ensure that stormwater from surrounding lands did not enter the Canal to pollute; bridges to carry major roads; and 'occupation bridges' to allow access for property owners. Throughout the late-19th and early 20th century the water supply through the Upper Nepean Scheme was managed by a resident engineer who lived on site in various locations over time including Prospect Reservoir, Potts Hill and Pipe head. Maintenance men and inspectors were living along the Canal housed in cottages owned by the Water Board. There were also valve controllers living at the weirs at the southern end and Prospect Reservoir in the north, to regulate the discharge of water along the Scheme. Most of these houses have been demolished, but the sites of some remain in archaeological form… Day-to-day communications between workers were enabled by a telephone line along the Canal's length, which was in operation by 1898. Some of the original poles from this line still exist within the Canal corridor. Movement along the Canal was assisted by roads or tracks alongside, which were

gradually added from the mid-to late 1890s. In some areas access was difficult until 1935 when the larger creek crossings were bridged… Larger scale repairs and maintenance were usually scheduled during winter, when lower demand for water allowed sections of Canal to be de-watered. By the 1900s this included relining some lengths of open canal. In the early 20th century the demand on the scheme increased with Sydney's increasing population. In 1902 a Royal Commission was established to make a full inquiry into Sydney's water supply. This considered a range of matters across the supply network including the Upper Canal. Although its initial recommendations were to undertake major works to the Nepean Tunnel, only minor work was required to bring the Upper Canal's capacity to its current 150 million gallon per day capacity. This included improving flow characteristics by concreting rough spots on the bottom and sides of the canal and tunnels and replacing some of the stone pitching with concrete. By-passes were also provided around the wrought iron aqueducts to enable their internal maintenance… A 54" diameter woodstave main was built from the Upper Canal at the 39 mile point to take water directly to Pipe Head basin. In 1937 it was replaced with permanent 72" diameter steel main between the Upper Canal at Prospect Reservoir and Pipe Head (Guildford). In 1958 when water from Warragamba (Dam) became available an 84" diameter steel pipeline was commissioned. The 1920s and 30s also saw construction of a range of new over-bridges and flumes, improving access and water quality. Another phase of bridge and flume upgrades occurred in the 1970s and 80s. The cottages occupied by maintenance staff along the Canal appear to have passed out of use at this time… In the 2000s all of the trash racks at the tunnel and aqueduct portals were replaced and new safety railing installed at various points along the Canal system to ensure safer working conditions for operational staff. This period also saw a range of works to prevent or rectify impacts of coal mining subsidence including propping and re-lining of aqueducts, propping and repairs to collapsed or unstable sections of open canal and temporary raising of the freeboard…
