  "account": "Horseshoe Bay, a popular beach located in Port Elliot, South Australia, is projected to lose up to 12 meters of shoreline by 2050 if substantial engineering work is not undertaken. The impending erosion is attributed to rising tides, and the situation has prompted a call for urgent action from the local community. The beach, which is part of Alexandrina Council and attracts around 31,500 residents, is a significant tourist destination renowned for its picturesque views and surfing opportunities.\n\nVarious options are being considered to mitigate the erosion, including repairing and extending the existing breakwater, extending the seawall, and replenishing sand from external sources. Mayor Keith Parkes emphasized that a state government grant would be necessary to fund these costly initiatives. However, he stressed that the council cannot afford to do nothing, given the projected 12-meter loss by 2050.\n\nCr Parkes advocated for repairing the breakwater as a priority, alongside seawall upgrades and sand replenishment. These estimated costs range from $18 million for the breakwater repair to $1.5 million per year for sand nourishment and between $3 to $4 million for seawall repairs and extensions. The Alexandrina Council is one of many coastal councils grappling with the financial burden of maintaining coastal assets in the face of climate change.\n\nThe local council is currently in the process of deliberating on the appropriate course of action and has deferred a final decision until a workshop can be held to discuss the management of the entire 26-kilometer-long Alexandrina Council coastline. The state government's Coast Protection Board offers financial assistance, covering up to four-fifths of the costs associated with coastal protection projects.",
