1. INTRODUCTION

The draft 'Heathcote Ridge Program Report' dated December 2011 and the draft 'Strategic Impact Assessment Report' dated December 2011 was jointly exhibited with the ‘State Significant Site Study’ dated December 2011. This public exhibition and comment process meets the requirements of the EPBC Act and the NSW Environmental Planning and Assessment Act 1979 (EP&A Act).

As a result of the submissions made during the exhibition process, amendments have been made to the program which are incorporated into the final 'Heathcote Ridge Program Report' and 'Strategic Impact Assessment Report' dated August 2011.

The study and draft PR and SAR were exhibited from 14 December 2011 to 29 February 2012.

The Proponent (GLALC) has considered the issues raised in the submissions made during the exhibition period and has implemented various actions in relation thereto. This includes some significant changes to the structure plan and associated planning controls which are described in the final Program Report for the Strategic Assessment of the Heathcote Ridge Development, West Menai, under the Environment Protection and Biodiversity Conservation Act (1999) dated August 2012.

2. EXECUTIVE SUMMARY

Gandangara Local Aboriginal Land Council’s proposal for Heathcote Ridge at West Menai is the largest Aboriginal owned and managed project in Australia. Covering around 850 hectares, the project seeks to help address ’s housing and employment land shortages whilst still protecting two thirds of the site for conservation.

Capital raised by the fifteen to twenty year project will fund education, employment, housing and transport programs for Aboriginal people in Sydney’s south west in an effort to break welfare dependency and help Aboriginal people achieve the type of financial and social independence that other Australians take for granted.

The project itself will:  provide thousands of quality local jobs;  help ease local housing pressures;  enable more local residents to live near their work;  open up a spectacular conservation park for public enjoyment;  provide recreational and retail hubs for the local community;  rehabilitate areas degraded by decades of dumping; and  provide nearly $100 million of improved local roads and infrastructure at no net cost to government.

The Heathcote Ridge State Significant Site Study (SSS Study) was submitted to the Department of Planning and Infrastructure (DP&I) in December 2011 and publicly exhibited for a period of almost three months - to the end of February 2012.

The consultation with community, government agencies and interested stakeholders in the lead up to and during the formal consultation phase for the SSS Study has been extensive. GLALC hosted two immediate neighbour forums, three broader community forums and two community information display sessions with experts on hand to answer community questions. More than 30 different stakeholders have been directly consulted.

Following the exhibition and consultation phase, GLALC had an opportunity to consider all the submissions and take on board the variety of feedback received. An amended Land Use Structure Plan for the site has been prepared (Figure 1).

The key elements of the revised proposal are:  The provision of a conservation area comprising an area of 566 hectares (66.7%) of the site which is an additional 50 hectares;

J:\2009\09191\Reports\strategic assessment\FINAL JULY 2012\Response to EPBC Report - Final.doc 3

 Of the remaining 283 hectares of land, the proposed urban purposes comprise: o 51.4 hectares of employment land (including a new village centre) estimated to provide 4,700 jobs; o 182.7 hectares of land for residential and associated purposes including local open space capable of accommodating an estimated 2,400 homes (7,200 persons); o New sportsfields and other open space (17.2 hectares), provision for a school and community facilities; and o A visitors and cultural heritage centre as a gateway to the proposed Heathcote Conservation Area;  Creation of distinct residential neighbourhoods linked together via walking trails, pathways and a central collector road spine;  Provision of an east west arterial road connecting New Illawarra Road with Heathcote Road;  The provision of bushfire management measures including asset protection zones, access routes and water services and neighbourhood safe places.

Overall the project continues to deliver on GLALC’s vision to create a high quality, environmentally-sustainable new community that is well connected, protects important ecological areas, integrates with adjoining urban and bushland areas and provides a range of living, working and recreational opportunities in the .

The protection of both Aboriginal cultural heritage and important biodiversity on the site has always been a key consideration in the design of the development footprint. All the relevant studies, plus the guidance of an independent advisory committee, have resulted in a footprint that operates on the ‘avoidance’ principle.

There are no known Aboriginal sites in the development area and any potential sites in the footprint will undergo further investigation during the Development Application stage following rezoning. If any additional actual sites are found in the development footprint, they too will be protected. Any sites indirectly impacted will also attract management actions as the project proceeds depending on their type, location and most effective protection action on a case by case basis.

Similarly, the conservation area, now 566 hectares, will be managed under a Biodiversity Management Plan which will ensure the area is actively managed for conservation in perpetuity and funded by the capital raised by the project. This provides an offset ratio of 2:1 and is a net gain for the environment. The removal of the former southern precincts provides an expansion of the important north-south wildlife corridor running through the site.

While the reduction in traffic volume afforded by the reduction in the size of the employment area and residential areas is significant (trips on local and regional roads will be cut by approximately 40% from the exhibited plan), the proponent still proposes to upgrade a range of local infrastructure including funding the critical east-west transport link between Sutherland and Liverpool which will provide benefits to the community through reduction in travel times and provision of new public transport services.

In its entirety this proposal will assist the NSW State Government to meet housing and job targets, provide a new, vibrant integrated bushland community in West Menai and protect forever a large conservation area for the people of Sydney, Sutherland and beyond.

Lack of Demand for  The proposal does not demonstrate demand for the proposed Based on submissions received and Employment land addition of 71 hectares of new ‘employment land’ and forecast discussions with DPI, the amount of projections of 10,000 to 15,000 for the site can be achieved in the employment land has been reduced to 51.4 subregion. The ‘Economic and Social Benefits Study’ (Final Report ha and the nature changed. 2009) prepared for the proponent states, “The higher proportion of [employment land] supply relative to the quantity of jobs suggests that the study area [South Sydney] may already have capacity to accommodate more jobs within existing employment lands, before additional employment lands are required” (pg 38). This assessment was omitted from the Urbis 2011 report, which forms part of the applicant’s submission, though it is still consistent with the findings of the ELDP 2010 report.

 Demand for large sites is not a compelling argument The potential for a range of lot sizes is seen as advantageous.

 Take up rate for employment land questioned Noted, see above.

Since the exhibition of the Heathcote Ridge SSS, amendments have been made to the project which have reduced the development footprint to provide a higher retention of biodiversity values. As a result of these amendments, an additional 22.71ha of Angophora hispida – Eucalyptus haemastoma Heath-Woodland will be retained within the project area. Under the current proposed footprint, the project would directly impact 188.85ha or 78.66% of this community within the project area (previously 88.03% under the exhibited zoning plan) which represents 5.78% of the community within the locality (previously 6.47% under the exhibited zoning plan).

Retained areas of Angophora hispida – Eucalyptus haemastoma Heath-Woodland will be zoned E2 – Environmental Conservation and will be managed under a Biodiversity Management Plan.

Since the exhibition of the Heathcote Ridge SSS, amendments have been made to the project which have reduced the development footprint to provide a higher retention of biodiversity values. As a result of these amendments, an additional 2.11ha of Banksia ericifolia Damp Heath will be retained within the project area. Under the current proposed footprint, the project would directly impact 1.83ha or 16.84% of this community within the project area (previously 36.08% under the exhibited zoning plan). The reduction is proposed to occur in the south eastern portion of the community, which forms the largest extent within the project area.

Some retained portions of this community will be in close proximity to the development footprint. As noted within the Ecological Assessment (Appendix 9 of the SSS Study), the portions of the community adjacent to the development footprint will be indirectly impacted by edge effects and alteration of hydrology. The design of the development footprint has incorporated an APZ which includes modified vegetation and stormwater retention basins in an effort to minimise impacts to adjacent vegetation.

Retained areas of Banksia ericifolia Damp Heath will be zoned E2 – Environmental Conservation and will be managed under a Biodiversity Management Plan, which is proposed to include measures for enhancement and rehabilitation of Coastal Upland Swamp. Further details of the proposed content of the Biodiversity Management Plan are outlined within Section 5.4.3 of the Ecological Assessment (Appendix 9 of the SSS Study).

 Recommends that Leptospermum polygalifolium Damp Heath be  Leptospermum polygalifolium Damp included as CUS. Heath has been subject to modification with the majority of the community having been cleared prior to 1978. This clearance has resulted in the presence of a highly modified community and as such, as noted within the Ecological Assessment, it is difficult to ascertain specific details on distribution and conservation status given. The community has affinities with Angophora hispida – Eucalyptus haemastoma Heath- Woodland and Banksia ericifolia Damp Heath, the latter of which corresponds to the Coastal Upland Swamp EEC.

Cumberland Ecology undertook floristic analysis of the quadrats undertaken within Leptospermum polygalifolium Damp Heath in relation to the final determination for Coastal Upland

21

No Submitter Issues Raised Response and Mitigation Strategy Swamp. The results of this analysis indicated that this community does not conform to Coastal Upland Swamp. The analysis determined that very few of the species recorded within the relevant quadrats are characteristic of Coastal Upland Swamp. In particular, Leptospermum polygalifolium dominates the community within the project area but is not listed as a characteristic species for Coastal Upland Swamp within the final determination.

Additional information regarding the analysis of floristic data in relation to the final determination for Coastal Upland Swamp is provided within the SSS Study Response.

Since the exhibition of the Heathcote Ridge SSS, amendments have been made to the project which have reduced the development footprint to provide a higher retention of biodiversity values. As a result of these amendments, all 0.94ha of Lepidosperma neesii – Shoenus brevifolius Wet Heath will be retained within the E2 – Environmental Conservation zone. The northern edge of this community which adjoins the development footprint is proposed to be buffered by the establishment of an APZ.

Retained areas of Lepidosperma neesii – Shoenus brevifolius Wet Heath will be zoned E2 – Environmental Conservation and will be managed under q Biodiversity Management Plan, which is proposed to include measures for enhancement and rehabilitation of Coastal Upland Swamp. Further details of the proposed content of the Biodiversity Management Plan are outlined within Section 5.4.3 of the Ecological Assessment (Appendix 9 of the SSS Study).

 The removal of EEC Coastal Upland Swamp is not considered  Since the exhibition of the Heathcote acceptable Ridge SSS, amendments have been made to the project which have reduced the development footprint to provide a higher retention of biodiversity values. As a result of these amendments, an additional 3.05ha of Coastal Upland Swamp will be retained within the project area. The proposed amendment to the development footprint includes the reduction of vegetation clearance within south eastern portion of the community, which forms the largest extent within the project area. Under the current proposed footprint, the project would directly impact 1.83ha or 15.46% of this community within the project area (previously 41.04% under the exhibited zoning plan).

The proposed amendment of the development footprint has been developed to minimise impacts to the largest occurrence of Coastal Upland Swamp within the project area. The reduction is proposed to occur in the south eastern portion of the community, which forms the largest extent within the project area. Areas of Coastal Upland Swamp most impacted by the proposed footprint predominately comprise the smaller occurrences of this community within the project area.

Retained areas of Coastal Upland Swamp will be zoned E2 – Environmental Conservation and will be managed under a Biodiversity Management Plan, which is proposed to include measures for enhancement and rehabilitation of the community. Further details of the proposed content of the Biodiversity Management Plan are outlined within Section 5.4.3 of the Ecological Assessment (Appendix 9 of the SSS Study).

Conservation of 10.01ha of Coastal Upland Swamp within the project area, and the proposed ongoing management through the implementation of a Biodiversity Management Strategy, is considered a suitable outcome for the project.

 Cumberland Ecology undertook floristic analysis of the quadrats undertaken within Corymbia gummifera – Eucalyptus pilularis Woodland in relation to the final determination for Shale/Sandstone Transition Forest. The analysis determined that although the quadrats included some of the characteristic understorey and ground stratum species within the final determination, the dominant diagnostic tree species specified by the final determination are completely absent. Additional information regarding the analysis of floristic data in relation to the final determination for Shale/Sandstone Transition Forest and

Corymbia gummifera – Eucalyptus pilularis Woodland was initially considered to have potential affinities within the following SMCMA communities:

 -Woronora Sandstone Exposed Bloodwood Woodland;

 -Hinterland Sandstone Transition Grey Gum Forest:

 -Coastal Shale/Sandstone Forest; and

 -Southern Sydney Sheltered Forest.

Of these communities, Corymbia gummifera – Eucalyptus pilularis Woodland had the highest affinity with Woronora Sandstone Exposed Bloodwood Woodland. However, the presence of Eucalyptus pilularis indicated that the community could also share affinities with other SMCMA communities, hence it not being assigned an equivalent SMCMA community within the Ecological Assessment.

As this community was not considered to confirm to Shale/Sandstone Transition

No Submitter Issues Raised Response and Mitigation Strategy Forest, the design of the development footprint did not seek to exclude the extent of the community. The project will retain 40.03ha of this community, which represents 71.91% of the extent within the project area. It is considered that a sufficient representation of this community will be retained within the project area. The biodiversity value of this community will be increased through the implementation of a Biodiversity Management Plan.

 Since the exhibition of the Heathcote Ridge SSS, amendments have been made to the project which have reduced the development footprint to provide a higher retention of biodiversity values. As a result of these amendments additional areas of ridgetop and upper slope woodland and heath vegetation including Angophora hispida – Eucalyptus haemastoma Heath- Woodland and Corymbia gummifera – Angophora costata Woodland has been retained. Retained areas of these will be zoned E2 – Environmental Conservation and will be managed under a Biodiversity Management Plan.

As a result of these amendments, additional areas of potential habitat for Acacia bynoeana will be conserved, primarily within Angophora hispida – Eucalyptus haemastoma Heath- Woodland.

Additional occurrences of Acacia bynoeana have been recorded within the project area, including within the development footprint and within the conservation area. The individuals occurring within the conservation area will be protected under an E2 – Environmental Conservation zone and will be managed under a Biodiversity Management Plan. Management of known occurrences of Acacia bynoeana within the conservation area will include monitoring of the species and management of its habitats. This will assist in the ongoing persistence of the species within the project area. The persistence of this species can contribute

As such Allocasuarina diminuta subsp. mimica was not addressed in detail as it is not listed under the TSC Act or EPBC Act.

Habitat for this species is primarily comprised of Angophora hispida – Eucalyptus haemastoma Heath- Woodland. However, this species was also recorded within Corymbia gummifera – Eucalyptus punctata Woodland.

Allocasuarina diminuta has been recorded within Holsworthy Military Area. Given the records within the project area and surrounds as well as the presence of Hinterland Sandstone Dwarf Apple Heath-Woodland, the records are considered likely to be individuals of Allocasuarina diminuta subsp. mimica.

As noted within the Ecological Assessment, Angophora hispida – Eucalyptus haemastoma Heath- Woodland is the vegetation community that would be most impacted by the proposed project. The regional context of this vegetation community was taken into consideration in the impact assessment. As shown in Figure 4.2 of the Ecological Assessment, mapping by SMCMA indicates that Hinterland

Additional areas of this community and known occurrences of Allocasuarina diminuta subsp. mimica occur within Lucas Heights Conservation Area.

Since the exhibition of the Heathcote Ridge SSS, amendments have been made to the project which have reduced the development footprint to provide a higher retention of biodiversity values. As a result of these amendments, an additional 22.71ha of Angophora hispida – Eucalyptus haemastoma Heath-Woodland will be retained within the project area. Under the current proposed footprint, the project would directly impact 188.85ha or 78.66% of this community within the project area (previously 88.03% under the exhibited zoning plan) which represents 5.78% of the community within the locality (previously 6.47% under the exhibited zoning plan).

Reduction and modification of the corridors linking the central and northern portions of the project area to Holsworthy Military Area is not considered to lead to isolation of the site. Connectivity from the project area to Holsworthy Military Area will be maintained through retention of habitat along the southern portion of the western boundary. Within the project area, this connection is approximately 1km in length and extends further south of the project area. Connectivity will also remain to the north of the project area through Georges River National Park.

The reduction in linkages to the west is not considered likely to result in the extinction of the threatened species known within the project area. Approximately 566ha of the project area forms the conservation area. This provides sufficient habitat for a range of threatened species known and

No Submitter Issues Raised Response and Mitigation Strategy potentially occurring within the project area. For species with larger home ranges, connectivity exist primarily through a north south corridor, as well west through the southern portion of the project area and to the north of the project area through Georges River National Park.

Staged development is proposed, which will allow fauna to relocate into adjacent woodland without assistance by using surrounding habitat connectivity to facilitate dispersal. Habitat improvement resulting from the implementation of a Biodiversity Management Plan will enhance the retained corridors within the project area which will facilitate ongoing movements throughout the conservation area and adjacent land.

A suite of mitigation measures are either utilised or proposed to occur to minimise impacts to retained vegetation. These mitigation measures are outlined within Section 5.3 of the Ecological Assessment. Retained vegetation will be managed under a Biodiversity Management Plan, which is proposed to include measures for erosion and sediment control, weed management and monitoring of the effectiveness of mitigation measures.

As a result of these amendments, and changes to local hydrology. an additional 3.05ha of Coastal Upland Swamp will be retained within the project area. The proposed amendment to the development footprint includes the reduction of vegetation clearance within south eastern portion of the community, which forms the largest extent within the project area. Under the current proposed footprint, the project would directly impact 1.83ha or 15.46% of this community within the project area

59

No Submitter Issues Raised Response and Mitigation Strategy (previously 41.04% under the exhibited zoning plan).

The proposed amendment of the development footprint has been developed to minimise impacts to the largest occurrence of Coastal Upland Swamp within the project area. The reduction is proposed to occur in the south eastern portion of the community, which forms the largest extent within the project area. Areas of Coastal Upland Swamp most impacted by the proposed footprint predominately comprise the smaller occurrences of this community within the project area.

Retained areas of Coastal Upland Swamp will be zoned E2 – Environmental Conservation and will be managed under a Biodiversity Management Plan, which is proposed to include measures for enhancement and rehabilitation of the community and management of edge effects. Further details of the proposed content of the Biodiversity Management Plan are outlined within Section 5.4.3 of the Ecological Assessment (Appendix 9 of the SSS Study).

Conservation of 10.01ha of Coastal Upland Swamp within the project area, and the proposed ongoing management through the

Although it is off-sets not appropriate but the scale of the off-sets is also not recognised that the project will impact appropriate. the habitat for these communities and species, the combined avoidance, mitigation and compensatory measures to be implemented are likely to sufficiently ameliorate these impacts to the extent that no communities or threatened species are likely to become extinct as a result of the project.

Since the exhibition of the Heathcote Ridge SSS, amendments have been made to the project which have reduced the development footprint from 332ha to 283ha. The conservation area will increase from 511ha to 566ha. The amendments to the development footprint includes the reduction of impacts to EECs and threatened species habitat and reduction in the edge to area ratio. Additional information regarding these amendments is provided in the SSS Study Response.

Under the currently proposed footprint, the offset ratio for land within the project area would be 2:1 (previously 1.5:1 under the exhibited zoning plan). This ratio meets the minimum standard of 2:1

62

No Submitter Issues Raised Response and Mitigation Strategy recommended within the Interim policy on assessing and offsetting biodiversity impacts of Part 3A, State significant development and State significant infrastructure projects (OEH 2011).

Requirements for offsetting will vary depending upon the geographic location of a project because the nature and extent of human impacts varies across NSW, as does the proportion of the landscape that is conserved. As discussed within the Ecological Assessment, the project area is in proximity to a substantial reserve system that supports habitats similar to those within the project area and are afforded long-term security. For this reason, the need for an offset ratio well above the minimum standard is not considered necessary for the project.

The proposed avoidance, mitigation and compensatory measures proposed for the project are considered to sufficiently ameliorate the impacts of the project.

The Committee’s views were endorsed by Council on 31 August 2011 and are submitted in full as Attachment 1 to this submission.)

 The Aboriginal Heritage Assessment that forms part of the Discussed in response to DoP&I

No Submitter Issues Raised Response and Mitigation Strategy

Submission states that there are 41 recorded Aboriginal heritage sites and 40 newly recorded sites with proximity to potentially developable areas. In addition, Aboriginal people consulted as part of the process suggested two areas of potential Aboriginal cultural significance. However, it is Sutherland Shire Council’s view that the number and type of recorded Aboriginal heritage sites does not reflect the complete heritage value of the area. The Heathcote Ridge area is part of the biggest cultural heritage library and museum in Southern and South Western Sydney.

Agreed. This is the basis for the detailed management planning outlined in Section 8 of the MDCA report.  The study also needs to address the proposed land use mix and make specific recommendations as to what land uses are most compatible with the long term protection and management of the sites. The consultant’s report states on page 71 that “the most likely threat to Aboriginal heritage from future subdivision within the subject lands is related indirect impacts from increased visitation which is to an extent inevitable from the adjacent residential subdivisions”.

Bushfire  If the bushfire protection measures necessary to provide an Addressed in SSS Study (Appendix 11) and in acceptable level of risk to life, property and the environment response from RFS. cannot be implemented with certainty and in a way that results in acceptable economic, environmental and social implications, then the land should not be rezoned to allow for such development.

 Having regard to the overarching principles for rezoning of land for residential development contained in Chapter 2 of Planning for Bushfire Protection 2006, the proposed planning scheme fails outright to satisfy two of the principles and when the feasibility of the proposal is taken into account, fails to satisfy the remaining heads of consideration. These two principles (page 4 of Planning for Bushfire Protection 2006) are:

 Minimising the perimeter of the area of land, interfacing the hazard, which may be developed: Separation at the interface is proposed by  Council’s estimate is that some 40 kilometres of way of perimeter roads.

Fire fighting resources will potentially be spread more thinly, protecting multiple interface areas, as well as those existing interface areas at Menai. While the proposed development will break up the current fire path to Menai across the site, sufficient areas of bushland remain to pose a significant threat to this area.

 The economic viability of the east west connection is questionable. The theoretical ability to provide such access is not sufficient grounds for stating that the development is suitable on This is a matter for State Government bushfire grounds. It is also necessary to look at the social, environmental and economic costs of the necessary bushfire protection measures. In these terms, the proposed level of development which generates the need for such costly transport routes, is unsupportable.

Water Quality – DGs  Identify all watercourses, riparian land and wetlands that could Watercourses and riparian corridors have Study Requirements be potentially affected - The Riparian Corridors Assessment failed been identified and addressed. not met to identify all riparian lands and water courses likely to be affected by the proposal. No wetlands were mapped or identified as part of this process and no recommendations were made in relation to adequate buffer zones for protection of the wetlands on the site. Additionally, watercourses and riparian lands were not identified in the south eastern portion of the proposed development. Watercourse assessment and identification was also undertaken during a prolonged dry spell which is not conducive to accurate mapping of watercourses. Therefore it is considered that the proposal has not identified all watercourses, riparian lands and wetlands that could be affected by the proposal.

 Assess the potential impacts of the development on water quality This is a matter for consideration at DA and quantity of receiving waterways, riparian land, wetlands and stage. downslope vegetation: No data is provided as to the status of existing water quality in receiving waters and waterways. Many broad assumptions are made, but are not backed up by sampling data or even detailed site observations in downstream receiving waters. Without such baseline data is difficult if not impossible to accurately assess impacts to these environments.

80

No Submitter Issues Raised Response and Mitigation Strategy

Council has significant concerns over the accuracy and validity of this modelling given the lack of input data, including assumed degree of imperviousness of the various catchments, and the assumed performance of many of the WSUD measures on this site. Council is concerned that the WSUD measures proposed to treat and manage site stormwater are not appropriate for the shallow and clayey coils of this site and will result in suboptimal performance and excessive maintenance. There has no identification or assessment of impacts to wetlands on this site. Overall Council considers that the proposal has not assessed the potential impacts to receiving waterways, riparian lands, wetlands and downslope vegetation. The Riparian Corridor Assessment (Appendix  Establish minimum riparian widths required to maintain channel 8) states that: stability and significant ecological values: The Riparian Corridors Assessment (RCA) identifies appropriate riparian corridor widths DECC (2010) states that the Vegetated Buffer for much of the development to west of the site along Heathcote (VB) should be wide enough to protect the CRZ Road. There has been little or no assessment of such riparian from weed invasion, micro-climate changes, corridors to the south east of the site, nor has there been any litter, trampling and pollution and the assessment of the need for riparian buffers to the wetlands recommended width is 10 metres although this is present on the site. The RCA notes that the recommended subject to merit assessment. As a general rule, riparian corridor widths may be varied on a case by case basis, this assessment recommends a 20m buffer on each side of the CRZ for all 1st order drainage but no case specific justification is provided for any such CRZ's. However, a 10m VB is justifiable for some of variations. While riparian corridor widths are recommended for the 1st order drainage lines on the western large areas of the site there is no assessment of compliance of catchment where there is currently little the development with these recommended riparian widths. vegetation already present Council considers that while appropriate recommendations have been made for riparian widths, they have not been adequately Additional investigations have been applied to the whole of the development.

 Assess constraints and strategies for stormwater management: No infiltration is proposed. Measures are The Water Sensitive Urban Design Initiatives Report and the proposed and will be investigated in greater Stormwater Management Strategy, provide a catalogue of detail at DA stage. potential measures to manage stormwater. However there is limited to no assessment of their direct applicability to this site. In fact, much of the strategy ignores the constraints of the site, such as shallow soils and low infiltration capacity, making the majority of the proposed measures unsuitable for this site. Other strategies proposed rely on significant ongoing management from a centralised body, such the greywater reuse system, without providing any indication of what such a management system would be, how it would be managed and who would be responsible. Ongoing management of the stormwater system represents a significant constraint, posing a substantial financial and resource burden. There has been no consideration of how these matters will be addressed in the long term and no overall management proposal put forward. Overall Council considers that there has not been adequate assessment of any of the constraints of the site in relation to the proposed strategies for stormwater management.

 The applicant has proposed a network of pumping stations rising mains and gravity mains for the development to provide a better environmental outcome within the proposed Conservation Areas.

 Sydney Water has also indicated that the provision of a local recycled water scheme incorporating sewer mining would significantly reduce the impact of, and presumably reduce the cost of, any proposed sewerage system. The disadvantage of such a scheme would be that Sydney Water proposes no recycled water scheme for the development and therefore

 The disconnected urban form produces means that central playing fields will not serve the future community’s needs. In addition, Sutherland Shire has extremely high participation rates The development will generate a demand on organised sports at all levels. The proposed rate of active for open space similar to other open space simply falls far short of minimum requirements. The development in the Shire. However the distribution of playing fields should reflect the pattern and density Structure Plan has been amended to make of development. Given that Precinct 3 – Residential North and provision for additional playing fields in a Precinct 4 – Residential Core North make provision for over 1500 centralised location. Space is provided for dwellings, at least three (3) playing fields are required. passive open space also.

 These playing fields should be located with passive open space to enhance their utility. The residential population of Precinct 5 – Residential Frame West will combine with the higher population density of the local centre to create a significant precinct. As the central place, a further two (2) playing fields should be located with the school and passive open space. The physical separation of Precinct 6 – Residential South West and Precinct 7 – Campus Park South is such that future residents will not be able to readily access other playing fields. One playing field needs to be located in this precinct adjacent to the passive open space. Similarly, a playing field should also be provided to the community of 806 dwellings in Precinct 10 – Residential “The Bridges”.

 In total, Council estimates that at least seven (7) playing fields will be required to serve the planned community’s local sporting needs. To embellish the land to the standard required, an allowance in the order of $7 million dollars is required. As it currently stands, the draft VPA seriously under funds open space provision.

 The draft VPA also makes an allowance of $5 million for a 50 metre swimming pool. Sutherland Shire does not have the financial capacity to meet the ongoing costs associated with a
