The Public Health and Wellbeing Act 2008 specifies Council’s role in creating an environment that supports the health of the local community and strengthens the capacity of the community and individuals to achieve better health. Models such as the Environments for Health framework further guide councils to think broadly about public health and wellbeing. Particularly, the Framework identifies that the social, economic, natural and built aspects of the world around us have an impact on health and quality of life. Moonee Valley City Council acknowledges that our health and wellbeing are impacted by the places in which we live, work, play and visit. Background East West Link The Victorian Government is planning to build an east west road link across Melbourne, spanning approximately 18 kilometres across the city. This project has been divided into an Eastern section and a Western section, with the Eastern section. The Eastern section will connect the Eastern Freeway with CityLink, and will include a tunnel section, taking the road underground across parts of Melbourne, with above ground sections of road linking to the Western section. The Western section will link the Port of Melbourne to West Footscray and the Western Ring Road. This section will be completed in stage two, and is yet to receive funding commitment. An indicative project map (the referenced design) for the first stage of the East West Link has been developed, however the full extent of the impact the project will have on Moonee Valley and our residents. From the information currently available it is likely that the East West Link will increase noise and air pollution for people living in, and visiting, areas around the new freeway. Our community The City of Moonee Valley is a largely residential area covering 43 km², located between four and 13 kilometres from Melbourne's CBD. The city is divided into three wards – Rose Hill, Buckley and Myrnong. Around 116,000 residents or 45,000 households call Moonee Valley home. The community is culturally and linguistically diverse, with more than a quarter of the population born overseas. East West Link: the health effects of proximity to major roads Page 1 Demographic data1 for the three suburbs within Moonee Valley that are most likely to be impacted is included below. Flemington Overall, 21.9 per cent of the Flemington population was aged between 0 and 17 and 30.1 per cent of households had children, with 12 per cent of households having young children. Flemington is the suburb with the lowest Socio-Economic Indexes for Areas (SEIFA) index (892), indicating that the population of this Moonee Valley suburb experiences the most disadvantage when compared to other Moonee Valley suburbs. In the 2011 Census, relatively high levels of unemployment were recorded in Flemington (10.7% of the labour force) and Travancore (10.6%). A higher incidence (33.%) of households in Flemington fall within the lowest quartile of household income (less than $871 per week) when compared with greater Melbourne. Health inequalities are demonstrated by the findings of the 2012 health screens conducted with the Flemington African Australian community. 71.8 per cent of respondents were overweight or obese, higher than national levels. In addition, 13.8 per cent of respondents were measured to have probable Type 2 diabetes, almost four times the national average.2 Health screens also found that healthy sleep habits were of concern with one in ten individuals sleeping less than five hours per night. Moonee Ponds Overall, 19.1 per cent of the population was aged between 0 and 17, and 18.6 per cent were aged 60 years and over. Of the Moonee Ponds population, approximately one-quarter (24.3%) are parents or homebuilders. Households with children account for 37.2 per cent of households and 17 per cent of households have young children. Travancore Overall, 34.1 per cent of the population are part of the young workforce and 21.3 per cent fall within the ‘tertiary education and independence’ category. 17.9 per cent of households have families, 8 per cent with young children. 1 Moonee Valley Profile .id, (2013).

East West Link: the health effects of proximity to major roads Page 2 Literature review Negative health outcomes associated with major roads are well established.3 It is important to consider the available literature regarding health impacts of major roads, given sections of the East West Link in Moonee Valley will be above ground. Many studies consider the health effects of new roads above and beyond road traffic incidents4 and numerous systematic reviews have found statistically significant associations between residential proximity to traffic and one of a number of adverse health effects.5 The World Health Organization (WHO)6 investigated health effects of transport-related air pollution in 2005. When considering the impact of traffic-related pollution in Europe, WHO estimated that the death rate is on par with that of road toll deaths.7 In a review of the urban development and transport impacts on public health with particular reference to Australia,8 the negative health effects of pollutants included: Exposure to particulate matter has been associated with a short-term increase in mortality and morbidity from cardiovascular and respiratory diseases. Studies have found long-term average mortality rates 17 to 26 per cent higher than expected in communities with high levels of fine particulate matter. Diesel exhaust and nitrogen dioxide have been tied to increased asthma symptoms and response to allergens. Exposure to diesel exhaust has been associated with increased rates of lung cancer and mortality and morbidity. Air toxics can cause negative health effects including cancer and respiratory, neurological, reproductive, and developmental effects. Long-term exposure to traffic-related air pollutants have shown a variety of health risks, including: o significant increase in the risk of death from cardiopulmonary causes o significant increase in asthma prevalence in children o impacts on lung development in children o increased cardiac arrhythmias.9 3 Van Poppel, M., Panis, L.I., Govarts, E.A., Van Houtte J., Maenhaut, W.

East West Link: the health effects of proximity to major roads Page 3 It has also been demonstrated that exposure to air pollution, particularly common in urban areas, is an independent risk factor in adverse birth outcomes such as pre-term birth and low birth weight.10,11 In addition to transport noise having effects on physical health, some research documents the link between noise and negative emotional states.12 Literature varies when estimating the distance of living proximity associated with health impacts; this in part is due to the broad range of measures (particular pollutants or contaminants). Some research suggests that “persons [residing] or spending substantial time within 200m of highways are exposed to [numerous] pollutants more so than persons living at a greater distance, even compared to living on busy urban streets”.13 Other research has found significantly elevated levels of pollutant concentration both indoor and outdoor within 50 meters of major roads due to roadway emissions.14 It is also important to consider whether negative health effects are likely to affect some groups of people more than others. Research by Black and Black (2009)15 identify groups of people who are more vulnerable to the negative health outcomes associated with transport impacts. These groups include the elderly, young children and children with asthma and persons with diabetes. Application Fair Foundations the VicHealth framework for health equity describes the social determinants of health inequities. The framework considers social position within three layers of influence: socioeconomic, political and cultural context, daily living conditions and individual healthrelated factors and how this leads to differences in health and wellbeing outcomes. Exposure to increased road traffic, noise and air pollution is likely to have an impact on daily living conditions for Moonee Valley residents, particularly those residing in Flemington, Moonee Ponds and Travancore. The reviewed literature indicates that the health impacts of the East West Link will are likely to be negative and broad. There is also evidence to suggest that health inequities will be heightened and that particular populations are at a higher risk of negative health outcomes due to their age and existing economic and health vulnerabilities. 10 Yorifuji, T., Naruse H., Kashima, S., Takao, S., Murakoshi., T., Doi, H.
