Protecting and enhancing coastal environments Print

Due to the sensitivity and values of estuaries and coastal margins, it is important to provide coastal environments with a resilient buffer to the effects of stormwater runoff. 

Upper catchment WSD responses reduce combined sewer overflows, mitigate lower catchment flooding, and capture contaminants prior to entry into marine environments. In particular, sediments should be captured before entrained contaminants such as heavy metals accumulate in marine sediments and bio-accumulate in benthic fauna (ARC, 2004). 

Point source stormwater management is important for coastal and marine environments, including buffering land use activities, managing coastal outfalls to prevent erosion, and ensuring a level of water quality treatment appropriate for the sensitivity and values of the coastal receiving environment. ​
