TThe densification of housing along the edges of the Linear Park negates decades of scientific advancement towards the improvement of coastal water quality and marine life. By infilling backyards with housing and concrete driveways, we reduce the area of land available for uptake of rainwater. Instead, rain falls onto roofing and concrete that is delivered into the storm water system, including the River Torrens. The River Torrens is part of an urban catchment that receives and carries pollutants from our urban activities to our coast. This delivery system has driven loss of marine life, with the larger population-sizes causing larger losses (Gorman et al. 2009).
It is worth knowing that our state scientists and managers have pursued environmental improvements needed to underpin the recreational and commercial values of coastal Adelaide. These improvements represent millions of dollars of investment in science and infrastructure for the long-term benefits of South Australia. By recognizing this pursuit and investment, a better considered 30 –Year Plan is needed for the long-term benefit of South Australians.
