Presentation title: History never repeats?

This paper presents a number of thoughts on the potential implications for the contaminated land sector resulting from large scale redevelopment planned to make Auckland the world’s most liveable city over the next 30 years.  Council’s contaminated land specialists have a pivotal role in directing resources and expertise, enabling appropriate development and managing health and environmental risk. The Auckland Plan and the Unitary Plan are planning for a predicted population growth of an additional one million persons seeking the opportunities and quality of life that the region has to offer.  This growth will be accompanied by an increase in demand for housing, with something like 400,000 additional dwellings being required by 2040.  It also follows that there will need to be expanded commerce and industry to provide workplaces, not to mention infrastructure and support services.  Auckland’s historical growth has seen a range of industries including gas works, manufacturing, military sites, vehicle related industry and intensive horticulture that have contributed soil contaminants, which have then been moved around the region through indiscriminate soil transport and filling.  Ubiquitous contaminants include asbestos containing materials and lead which remain in situ around industrial and residential sites. The draft “blue print” for the future growth of greater Auckland has identified that between 60 and 70% of growth will need to be accommodated through urban intensification.  Brownfields redevelopment will comprise some of this and the management of soil contamination under the NES will feature for many industrial, commercial and residential sites linked to the HAIL.  Redevelopment of historic landfill and fill sites is already being undertaken and will intensify.  Greenfields development of rural lands, particularly those with an intensive horticulture past, will also trigger NES controls.  This is a good time for the contaminated land sector to focus on the future and identify the potential challenges that will come with such unprecedented growth and development.
