wamberal beach erosion management

Council has been working with the community on a long-term management solution to the Wamberal Beach erosion issue for some time. hosting community workshops to refine the process and the draft concept designs. July 17, 2020. Watch the full report in the video above. At this stage, concept designs for a terminal protection structure (seawall) and sand nourishment solution are being worked through. Another company, Royal Haskoning DHV, looked at short-term measures. “Higher sea levels will result in the increasingly frequent inundation of hundreds of properties surrounding the Terrigal lagoon, the loss of the beach, and impacts on council assets such as water, electricity, sewerage and roads,” it found. We do not yet know what the planned footprint of each concept option is and what the land implications will be. Instead it continued to approve development, requiring new homes to have deep piles into the sand. Wamberal Beach Terminal Protection and Sand Nourishment - Investigation and Concept Design This project is currently open for consultation. Wamberal Beach has a long history of coastal erosion, with beachside infrastructure exposed to impacts from coastal storms. Fire & Rescue officers were on Thursday night called to Ocean View Drive in Wamberal to respond to several beachfront homes at "significant" risk of structural collapse due to coastal erosion, Terrigal Fire Station said on Facebook. This was prepared by the former Gosford City Council but only certified by the Minister in April 2017 after formation of Central Coast Council, as published in the Government Gazette on 2 June 2017. Two homes fell into the sea at Wamberal in 1978 during big seas, as this image shows. Most recently, Council investigated the erosion issue and what to do about it, through a Coastal Hazard Definition Study (CHDS, 2015), a Coastal Zone Management Study (CZMS, 2017) and the preparation of a Coastal Zone Management Plan (CZMP, 2017). There is no simple answer to this question. The Marsden Jacobs study on Wamberal was informed by a detailed study by the then-NSW Office of Environment and Heritage, which found that the coastal processes acting on the dune that separates Terrigal lagoon from Wamberal beach – and where the most vulnerable houses are located – are complex and will get worse with sea level rise. This is because all of the seawall options would result in the loss of beach areas, and without sand replenishment the beach would quickly disappear, with significant costs to the local tourism industry. These materials have been placed in front of the erosion scarp by various entities since the 1970’s. Against the tide: storm-battered residents cling to beachfront homes on Australian east coast, NSW Central Coast houses partially collapse after beach erosion caused by swells. In May 2020, Council engaged Manly Hydraulics Laboratory to prepare concept plans for a terminal protection structure (seawall) and sand nourishment solutions for Wamberal Beach. This coastal engineering and economics study will ensure Council progresses the Wamberal Beach based actions in the CZMP. Mayor Smith said a working group had been established to implement the Coastal Zone Management Plan options for Wamberal Beach which also considers erosion measures. Name wamberal-lagoon-nature-reserve-plan-of-management-930003.pdf The nature reserve encompasses one of the best remaining examples of coastal lagoon, wetland and barrier dune on the Central Coast. Rocks and rubble have been placed along the back of the beach by various governments and individuals during this time. public exhibition of draft documents (CZMS, CZMP), CZMS - targeted community presentations to discuss potential management options for each study area, including Terrigal/Wamberal (2015), community drop-in sessions (include at Terrigal SLSC; 2015). There are emerging opportunities for sourcing sand for nourishment purposes at Wamberal Beach, which were not available previously. Beachside properties along the shore near Wamberal Beach are on the brink of falling into the ocean after days of big swells.

Two storms in the 1970s ruined several homes, a point at which the council declined to buy back the properties and instead continued to approve development, The Guardian reported. Yet there remains concerns about both the environmental impact of seawalls and how they will perform in the future. Beach erosion continues after heavy seas lashed Wamberal Beach on the NSW central coast. However many seawalls on the Australian open coast are over 100 years old. When the beach system naturally recovers (builds out) over time, the rock and rubble become buried. Picture: NCA NewsWire/Troy Snook Picture: NCA NewsWire/Troy Snook By Anton Nilsson Council understands that the best coastal erosion management solutions are developed when state and local governments, residents and the broader community work together. Marsden Jacobs said it was not clear which seawall option would lead to the fastest loss of the beach but all would result in an unusable beach by 2064, without a major sand replenishment program, “The cost of sand replenishment is very high and outweighs the benefits of retaining a beach in front of a seawall,” it said. There are many steps to work through before a long-term solution can be implemented at Wamberal Beach. Indeed, the solution is complex - requiring input and agreement from a number of parties. The management of coastal erosion by Central Coast Council is guided by the management actions within the Certified Gosford Open Beaches Coastal Zone Management Plan 2017 (including the Emergency Action Sub-Plan for Wamberal). Residents from Wamberal Beach on the NSW Central Coast have been evacuted as homes collapse due to severe erosion of sand dunes. In May this year, Central Coast council commissioned Manly Hydraulic Laboratory to design a concept plan for a seawall solution. Has Council applied for funding from the $83.6 million available from the State Government’s Coastal Management Grants Program? Coastline Management Plan In the mid-1990s a Coastal Processes Study (PWD, 1994) and Coastline Management Plan (WBM, 1995) detailed the nature of the erosion issue and recommended either ongoing sand nourishment or a terminal protection in the form of a seawall. Gosford City Council formed a coastal committee in 1984. An Environmental Impact Statement (EIS) for the coastal protection solution was finalised in 2003 by MHL, which found that a seawall with periodic small-scale sand nourishment was acceptable. Wamberal Beach Terminal Protection and Sand Nourishment - Investigation and Concept Design. What are the next steps for the Wamberal Beach terminal protection structure (seawall) and sand nourishment project? continue with the coastal engineering and economics study looking at concept option and feasibility for implementing the Gosford Beaches CZMP actions, continue to consult with the community on erosion solutions for Wamberal Beach at all stages of the study, continue to participate in the NSW Government Wamberal Seawall Advisory Taskforce. However, in the absence of a long-term solution the risk of further erosion impacts will remain. Wamberal Beach erosion following this week's storms. Developing a methodology that can support the coordinated delivery of an embayment-wide solution across a mix of private and public land is one of the key challenges that needs to be worked through. These two beaches are located near Gosford, 80 kilometres north of Sydney. The beach at Wamberal was vulnerable to erosion long before the first homes were built. Any long-term solution must be technically feasible, legally permissible, environmentally and socially acceptable and financially viable. Erosion at Wamberal has been a problem since before the first homes were built there. Who decides if the proposed terminal protection structure (seawall) and sand nourishment works program is delivered? Asbestos and other building waste has been unearthed along Wamberal beach following severe erosion. NSW weather: heavy rain, flooding and huge waves threaten homes on south and Central Coast. The terminal protection structure (seawall) and sand nourishment have been recommended by experts as a preferred erosion strategy at Wamberal Beach for several decades. “Only a Planned Retreat option (Option 8) -retreat by managing the duration, type and intensity of future development within the coastal hazard area – provided greater benefits than a continuation of the current approach.”. In the late 1990’s a range of coastal protection options were proposed by WRL (1998) for Council.
