There are many stakeholders involved in this decision-making process including: Council, NSW Government, beachside property owners, interest groups and the broader community members. It's a great beach to go to if you want to break away from the hustle and bustle of Terrigal. The terminal protection structure (seawall) and sand nourishment have been recommended by experts as a preferred erosion strategy at Wamberal Beach for several decades. Recovery works continue at Wamberal Beach following severe erosion which saw homes partly crumble into the ocean back in July. The Taskforce meets on monthly basis. How much will the proposed program of works cost. We will be seeking the communities experience and input again through the current MHL coastal engineering and economics study that is underway. Wamberal is famous for its Wambie Whopper hamburgers at a takeaway shop not far from the beach. Following the July 2020 storm event which saw the emergency response place 2,400 tonnes of large rocks, over 2,000 tonnes of rock bags and 4,000 tonnes of sand along Wamberal Beach, the NSW Government Wamberal Seawall Advisory Taskforce was set up to provide technical advice and assistance to Council in progressing a long-term solution for Wamberal. Coastline Management Plan The coastal economics assessment will be help guide the development of possible funding models. Council adopted the EIS for the seawall and sand nourishment solution in 2004. 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. The program of works would be delivered to appropriate coastal engineering standards. This funding would be the catalyst to really tackle the complexity of erosion at Wamberal Beach. Wamberal Beach Erosion. Following days of powerful surf barrelling towards beach-front properties, severe beach erosion is occurring at Wamberal. Wamberal Beach has a long history of coastal erosion, with beachside infrastructure exposed to impacts from coastal storms. Any long-term solution must be technically feasible, legally permissible, environmentally and socially acceptable and financially viable. At this stage, concept designs for a terminal protection structure (seawall) and sand nourishment solution are being worked through. Whereas Terrigal Beach attracts large summer crowds, Wamberal is quiet and spread out. There are no plans in place to purchase private property. The Wamberal Terminal Protection Working Group was established in November 2017 to bring together all the stakeholders to progress discussion relation to coastal erosion at Wamberal Beach - representatives are Council staff, Department of Planning and … A ‘Seabee’ seawall, spanning lagoon to lagoon, was designed and modelled in detail. Dr Phil Watson has been appointed as the Chair of the Taskforce with Council’s CEO, Member for Terrigal Adam Crouch MP, representatives from the Department of Planning, Industry and Environment, and Council’s appointed project manager. 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). The seawall footprint from the previously approved Wamberal terminal protection structure was located across a mix of private and public land. The preferred long-term solution for Wamberal Beach includes a sand nourishment program to ensure long-term outcomes for Wamberal Beach. Sand nourishment is central to the long-term solution being investigated. This earlier study assessed the economic merits of the generic coastal management scenarios for Wamberal Beach. How long will any proposed (seawall and nourishment) solution last? (Nine)Wamberal on the NSW Central Coast has been hard-hit … When Wamberal is in an eroded state, the ad hoc protection materials interact with the waves. This coastal engineering and economics study will ensure Council progresses the Wamberal Beach based actions in the CZMP. The next steps for Wamberal Beach are as follows: Who will pay for the delivery of the long term (seawall and nourishment) solution? The $400,000 study is being funded by both the state government and council. The coastal engineering and economics study underway is being co-funded (50:50) through the NSW Coastal and Estuaries Grants Program. Good coastal management outcomes can only be achieved through active involvement and support from coastal communities. 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. There is no guarantee that all the factors required to facilitate the seawall and sand nourishment solution will be satisfied. These questions include: A funding model is yet to be determined. Coastal erosion is a way of life in Wamberal, north of Sydney. In the late 1990’s a range of coastal protection options were proposed by WRL (1998) for Council. On 29 January 2019, Central Coast Council resolved to work with the NSW Government to progress designs for a terminal protection structure (seawall) at Wamberal. such as erosion, deposition, beach recession and sea level rise are complex and interact with Terrigal beach and Terrigal lagoon. In addition, workshops were held with the Council’s Catchments and Coast (advisory) coastal sub-committee established at that time. Boulders rubbish, car bodies and the remains of houses were dumped as a makeshift wall and the sand eventually returned. The big swells that have pounded the New South Wales coast this week have caused a lot of damage. View our privacy statement. 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. There are many steps to work through before a long-term solution can be implemented at Wamberal Beach. The community were consulted as part of the Gosford Beaches Coastal Zone Management Plan (CZMP; 2017), and preceding Coastal Zone Management Study (CZMS; 2015). view the frequently asked questions available below, TW11: Terminal protection- Council to action review, design and funding of terminal protection structure for Wamberal, TW14: Investigation of sources of sand and determination of the feasibility of beach nourishment for Wamberal Beach. sea level rise). Wamberal Beach erosion following this week's storms. This assessment will incorporate up-to-date cost estimates specific to the concept design being proposed. 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. But as the Marden Jacobs report detailed, the trade-off from protecting about 60 beachfront properties with a seawall would be the potential loss of visits due to the loss of the beach. An east coast low has whipped up the strong waves for several days, causing erosion. The Gosford Beaches Coastal Zone Management Plan (CZMP) contains an action to progress a long-term solution for Wamberal Beach erosion. 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. 18 homes at Wamberal will be evacuated today, as wild seas continue to batter the Central Coast. Wamberal Beach is one of the locals’ favourite beaches on the NSW Central Coast. However, the decisions were made hastily and without extensive community consultation. “A seawall will provide benefits to beachfront properties by reducing the impacts of coastal processes,” the report by Marsden Jacobs found. 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). Former coastal council member and engineer Angus Gordon says the answer lies in changing the Local Government Act to allow councils to recoup the costs of the seawall from waterfront property owners over time, though a long-term levy on the affected properties.

TW15: Beach nourishment coupled with a terminal revetment to increase the buffer against storm erosion. 211K Views . 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. The CZMP outlines a preferred protection solution (terminal protection structure) and the technical studies needed to inform further decision making, but it does not provide for the delivery of a seawall and sand nourishment. There is no simple answer to this question. Coastal beach erosion and home damage at Wamberal on the NSW Central Coast. Chris Rogers, who lives on … Letting properties slide into the sea is politically unpalatable and the cost of buying up the waterfront properties far more expensive than it was 50 years ago when the first problems emerged. Terrigal lagoon sits directly behind Wamberal beach and currently drains into the sea just to the south of the slipping houses, but locals says the lagoon used to drain to the beach at a different spot, suggesting active coastal processes. Councils up and down the coast face a dilemma: should they require their entire ratepayer base, which often includes many retirees, to support costly seawall projects that often involve ongoing requirements for beach replenishment? What is the MHL coastal engineering and economics study? A CZMP Community Engagement Strategy was developed and endorsed by Council in November 2013, this document guided consultation throughout the CZMS – CZMP processes. Council will be engaging with the Wamberal and broader Central Coast community throughout this project. These materials have been placed in front of the erosion scarp by various entities since the 1970’s. Coastal engineers have also been called in to assess the damage. In a Facebook post, Terrigal Fire and Rescue said the homes were at "significant risk of structural collapse due to beach erosion." The June 2016 storm again decimated the beach at both locations. Technical, financial, environmental, social, legislative and land ownership challenges must be addressed. What are the next steps for the Wamberal Beach terminal protection structure (seawall) and sand nourishment project? A report says a trade-off of protecting about 60 beachfront properties with a seawall would be a potential drop in visitors due to loss of the beach. The beach at Wamberal was vulnerable to erosion long before the first homes were built. Beachside properties along the shore near Wamberal Beach are on the brink of falling into the ocean after days of big swells. A cost-benefit analysis of options for a seawall at Wamberal beach commissioned by the New South Wales government in 2017 found that none of the six engineering options considered would deliver a net public benefit and that erosion would only increase with rising sea levels. “However, in the longer term, more properties in this area are likely to experience greater damage and loss of property values from the increased flooding of Terrigal lagoon associated with sea level rise. Wamberal on the NSW Central Coast has been hard-hit by beach erosion after the coastline was smashed by strong winds and wild seas. The plan was certified by the Minister for the Environment in May 2017 and identifies several key management actions for Wamberal Beach, including: Were the community consulted through the CZMP? Funding however could not be secured and the approved protection works did not progress further. Gosford Beaches Coastal Zone Management Plan adopted by Council and certified by the Minister, Council resolution to progress Wamberal CZMP actions, Engage independent experts to investigate and develop concept designs, Phase one community consultation on values and uses for Wamberal Beach, Phase one community consultation results available, Phase two community consultation (workshop) begins, Phase two community consultation results available, Concept design placed on public exhibition, register to attend a drop-in information session, stay updated on this project by registering here, register to attend a virtual drop-in information session, Submit a question and we’ll get back to you, Gosford Beaches Coastal Zone Management Plan (CZMP), Coastal Hazard Definition Study (CHDS, 2015), Coastal Zone Management Study (CZMS, 2017), Coastal Zone Management Plan (CZMP, 2017). Other schemes, at Collaroy, have involved subsidies from state and local government, with waterfront home owners still facing $400,000 bills to build the wall. “This loss of visitors may create some concern in the wider Central Coast local government area, especially as 32% of the beachfront properties that would potentially be protected by a seawall (at the expense of the beach) are only occupied occasionally,” Mardsen Jacobs said. Emergency services and Central Coast Council have met with locals who's homes are at risk of washing into the sea. Four years later in June 1978, beach and dune erosion attributed to an intense rip cell undermined and destroyed two houses at Wamberal (Plate 1). Or should councils be looking at adaption strategies that accept that coasts are dynamic – some areas such as Wamberal, Collaroy, Byron Bay and Port Stephens more so than others – and that the battle to protect inappropriately located development will become even more difficult due to sea level rise?

Erosion at Wamberal has been a problem since before the first homes were built there. Since that time Council has actively pursued a coastal management strategy for Terrigal/Wamberal Beach to secure development while protecting the recreational beach amenity as a community asset. The NSW Government has laws in place that guide how the NSW coastline is managed. The Gosford Beaches Coastal Zone Management Plan (CZMP) contains an action to progress a long-term solution for Wamberal Beach erosion. Terrigal lagoon sits directly behind Wamberal beach and currently drains into the sea … This document also outlines the responsibilities of local, state and private landholders in the implementation and funding of identified management actions on … Has Council applied for funding from the $83.6 million available from the State Government’s Coastal Management Grants Program? Did you know that ad hoc protection works have been placed at Wamberal Beach for many decades? The Central Coast Council has also urged the NSW government to fast-track recommendations of the Wamberal Beach Management Options: Cost Benefit snd Distribution Analysis Report finalised in 2017. Finding a solution that strikes the right balance is not straight forward. Today the erosion escarpment left by these storms crosses some 90% of the seafront properties. Mr Persson said he had been administrator for three councils with significant coastal erosion issues, however none were as great as the problems at Wamberal. There are several financial questions that need to be worked through prior to the delivery of a long-term solution for Wamberal Beach. Two storms in the 1970s – in May 74 and June 78 – saw several houses on the strip claimed by the sea. Yet there remains concerns about both the environmental impact of seawalls and how they will perform in the future.
