Coffin Bay

  • client: District Council of Lower Eyre Peninsula, SA
  • year: 2012
  • collaboration: TLC

DesignFlow first developed a strategy to mitigate stormwater coastal outfalls across Eyre Peninsula and then designed a rain garden to upgrade CoffinBay’s main foreshore.

The award-winning rain garden treats stormwater from the surrounding streets and business area, before flows discharge at the town’s main swimming beach. Local limestone was used for the retaining walls and for erosion protection.
