ISBN 1-85312-917-8 Design for sustainability in the Hill Road Corridor precinct, Millennium Parklands, Homebush Bay, Sydney, Australia A,R. McCormick Hassell Pty Ltd, Australia Abstract The Millennium Parklands site comprises nearly 500ha of highly disturbed landscapes and sensitive habitats including woodlands, saltmarshes and intertidal wetlands. Once complete, the parklands wil~be one of the largest metropolitan parks in Sydney, The initial stage of development was completed prior to the Sydney 2000 Olympic and Paralympic Games. The parklands played a major role in providing a setting for the games. The Sydney Olympics were known as the Green Games, Sustainability was a key requirement of all Olympic projects. The design for the Millennium Parklands was used extensively to publicise how the Olympic Co-ordination Authority (OCA) met its sustainability objectives. This paper focuses on how the Hill Road Corridor precinct of the parklands was designed for water conservation and wetland habitat development. Located between the Athletes Village and the Olympic Stadium, the corridor was the site of a former landfill and ordinance disposal area. The parklands are acknowledged as one of the greatest legacies of the Sydney 2000 Olympic Games. The design is widely regarded as a model for how degraded sites can be returned to productive natural and cultural landscapes in major urban areas. 1 Introduction A multidisciplinary team led by HASSELL was appointed to undertake the conceptual design of Millennium Parklands in March 1997. An extension to this work involved the design development of the water management infrastructure and wetlands of the Hill Road Corridor Precinct in September 1997, Further concept refinement was done by team members in 1998/99, This paper draws upon the work done by the team over this period. The team membership is listed in Appendix A, © 2002 WIT Press, Ashurst Lodge, Southampton, SO40 7AA, UK. All rights reserved.

ISBN 1-85312-917-8 A project such as the design of Millennium Parklands is complex, and the diversity of skiils available via the team assembled for the project was necessary to ensure a holistic approach could be pursued and sustainable outcomes delivered. The Homebush Bay site selected for the development of many Olympic sporting venues and the Athletes Village was highly degraded. Some 160ha of the 760ha site was used for the mainly uncontrolled disposal of much of Sydney’s waste since the 1940’s. The residue of the site was developed for a variety of industrial uses including Sydney’s main abattoir and brick making plants and the navy’s largest armaments depot. Chemical, building products and other manufacturing industries also existed on the site. In addition to industrial pollution, the gradual filling of the bay/chanellisation of tributary waterways meant that about 80% of the land area at Homebush Bay was “new” lands ie, those derived from development. A key principle in the development of the Homebush Bay site for the Olympic Games was the desire to decontaminate and reinstate the degraded lands. For the Millennium Parklands, this meant not only the healing of the land but the re-establishment of the ecology and sustainable natural processes of the estuarine landscape, What made the design concept for Millennium Parklands novel was that the team proposed a “program” concept as well as a “physical” concept. This was aimed at providing a wider ownership or constituency for the parklands. One that extended beyond the obvious recreation consumer. The parklands were to be used to tell the story of how degraded sites can be healed, habitats re-created and natural processes reinstated. The program envisaged the involvement of scientists, artists and the community under the egis of the “Millennium Institute” to use the developing parklands for monitoring, research and inspiration. The Millennium Institute was also to be the vehicle for the “virtual park” to involve distant interested parties in the activities and evolution of the parklands. Such an initiative was to take advantage of the web based infrastructure, developed for the Sydney 2000 Olympic Games, and extended to explore various parkland themes, The design concept and some of the matters that led to its resolution, with particular emphasis on water conservation are the subject of this paper. 2 Millennium Parklands design concept overview 2.1 Vision The Olympic Co-ordination Authority (OCA) was committed to the delivery of a quality, visionary, ecologically sustainable and innovative design in the development of Homebush Bay (Refer Figure 2, over page).

It comprises the initial stage of Millennium Parklands development. The precinct is one of the most visible parts of the parklands and some two thirds of its length will comprise a park dominated by water.

ISBN 1-85312-917-8 “Homebush Bay will be a place of recreation, sport, education, training, employment and industry. One can visualise all of Homebush Bay as a huge park, a future park in which the interaction of development and landscape enables a sustainable relationship between our society and our ecosystems, and at the same time is a place which fosters positive human exchanges. The future park of Homebush must move beyond the concept of the picturesque landscape, beyond images of embalmed nature, and beyond the realm of landscape as a spectacle for the masses. The landscape at Homebush Bay is not intended to be experienced as a fixed element, nor an object of desire, but an on-going process of evolution”. The concept developed for Millennium Parklands is to provide a place and a program which is treasured by the community for the opportunities it provides for recreational, inspirational and educational experiences derived from interaction with a diversity of distinctly Australian natural and cultural settings. The designers strove to deliver a design that not only responded to the inherent complexity of natural systems, but was an artful interpretation that helped tell the story of the place in a setting of great beauty. 3 Hill Road Corridor 3.1 Context Commissioning of the team to design the Millennium Parklands happened relatively late in the planning process for Homebush Bay. This was understandable given the imperatives dictated by the requirements to deliver major urban infrastructure capable of supporting the 2000 Olympic Games on a significantly degraded site. At the time of park concept team appointment, various government authorities and private enterprise organisations were involved in a range of projects along the Hill Road Corridor. These were largely focused on dealing with the resolution of single issues. In effect, those responsible for the various projects were lobbyists for realising their objectives with limited consideration of issues beyond their immediate area of concern. What was to be the titure prime use of the Hill Road Corridor (ie. as parklands) was not well represented at the project “table” at that time. Progress was moving apace on many fronts which would have a significant effect on the quality and function of the parklands. Some of the key projects underway at the time were as follows: ● remediation of both contaminated soils and unexploded ordinance; ● flood mitigation; ● freshwater wetland habitat enhancement; ● major road, busway and car park design; ● Athletes Village design; c Olympic related sports facilities design; and ● major services infrastructure design. © 2002 WIT Press, Ashurst Lodge, Southampton, SO40 7AA, UK.
