Marks Point Belmont South Foreshore Management Plan

The upcoming Marks Point and Belmont South Foreshore Management Plan focuses on erosion, inundation and public access along the foreshore at Marks Point and Belmont South and considers the impacts of rising lake levels. This plan is part of the implementation of the Marks Point Belmont South Local Adaptation Plan (LAP). We are reviewing concept designs for mitigation actions and preparing the draft Plan. It will be available for public review later this year.

The LAP implementation

Lake Macquarie City Council is now working to implement the adopted Local Adaption Plan for Marks Point and Belmont South. The plan will allow people to live and build in these areas, as sea and lake levels continue to rise.

We are working alongside local residents, community and stakeholders to implement the local plan. Council recently passed changes to development controls, including building heights, filling and adaptable housing. View the plan below.

About the Plan

Constructing sloping sea walls to protect the foreshore, raising and improving the design of infrastructure such as drains and roads, constructing new buildings with floor levels above projected flood levels and raising homes if required form the main actions in the plan.

The plan also recognises that retreat is not warranted in Marks Point and Belmont South and the adaptive approach outlined in the plan means that we plan for the worst and only act when necessary.

While the actions proposed in the plan will be spread over many years, up to the end of the Century, a more detailed 10-year action plan sets out specific tasks to apply new design standards to new buildings and infrastructure, review planning and development controls, and coordinate land filling with the raising of drains and roads.

    5 months ago

    With the end of the year fast approaching, it’s a good time to look back on what’s been happening behind the scenes this year to develop the draft Foreshore Management Plan for Marks Point and Belmont South.

    The Council and Community Working Group have continued to collaborate to build on the work completed for the Marks Point Belmont South Local Adaptation Plan. Throughout the year, the Group has met around ten times to progress investigations into issues and consider options to assist Council and the community to protect and manage our valuable foreshore areas.

    With the end of the year fast approaching, it’s a good time to look back on what’s been happening behind the scenes this year to develop the draft Foreshore Management Plan for Marks Point and Belmont South.

    The Council and Community Working Group have continued to collaborate to build on the work completed for the Marks Point Belmont South Local Adaptation Plan. Throughout the year, the Group has met around ten times to progress investigations into issues and consider options to assist Council and the community to protect and manage our valuable foreshore areas.

    When completed, the Foreshore Management Plan will provide guidance on how to implement foreshore protection works on public and private land. The Plan will help us to protect the foreshore from erosion in the short to medium term, without affecting the ability to adapt to permanent inundation over time or creating unacceptable impacts.

    It aims to address current and emerging issues impacting on the lake foreshore and residents and visitors to the area. Key issues identified by Council and the community include foreshore erosion and tidal inundation, public safety and amenity and foreshore access. The plan also incorporates long-term measures to protect communities against projected sea level rise.

    It’s a complicated task and we would like to thank and acknowledge the commitment from the Group’s volunteers and local residents in building strong foundations for the development of the draft Plan.

    Our current thinking is that the draft Management Plan will consist of four parts:

    • Part A: Why we need a Foreshore Management Plan for Marks Point and Belmont South
    • Part B: How the Plan was prepared
    • Part C: Key elements of the Plan
    • Part D: Implementing the Foreshore Management Plan

    In the coming months, the Group members will be reviewing draft foreshore concept designs and clarifying approval pathways for public and private works. We look forward to presenting the draft Plan for your review and feedback early next year. Stay tuned!

    If you would like ask the Council and Community Working Group a question or would like any further information, visit shape.lakemac.com.au/future-flood-planning or call Council on 49210333.

    Wishing you a Merry Christmas and wonderful New Year.

    A case study on tidal valves in Marks Point has been released by Local Government NSW for the Citizen Science and Foreshore Inundation Project.

    Marks Point is a low-lying area that experiences frequent tidal inundation from Lake Macquarie. Local tidal inundation is projected to increase as sea levels rise due to climate change.

    Marks Point is a low-lying area that experiences frequent tidal inundation from Lake Macquarie. Local tidal inundation is projected to increase as sea levels rise due to climate change. As part of the Marks Point and Belmont South Local Adaptation Plan, the community proposed to address this risk by using tidal flaps (or valves) on stormwater outlets to prevent the ingress of lake water into the stormwater system.

    In June 2016, with financial assistance from the NSW Government through its Environmental Trust (Local Government NSW / NSW Office of Environment and Heritage Building Resilience to Climate Change program), Council installed tidal flaps on two stormwater outlets at Marks Point to trial their effectiveness under local conditions. From June to December 2016, the community monitored the performance of the flaps during high tides and rainfall events.









    While the flaps were successful at preventing lake inundation during high tides, they caused the stormwater system to backup during rainfall events resulting in localised flooding. The trial has identified further design considerations including head pressure within the stormwater system.

    Thank you to the community members who were able to attend the onsite meeting on Thursday 27 July 2018 to discuss the draft designs for the Emily Street foreshore protection works. The following information is a summary of the meeting discussion and information:

    Council constructed demonstration foreshore protection works at the end of Emily Street in October 2015. Council has secured grant funding to undertake another demonstration project extending east of the existing works. The works will address current erosion and protect the foreshore in accordance with the Marks Point and Belmont South Local Adaptation Plan, while supporting ecological values.

    Thank you to the community members who were able to attend the onsite meeting on Thursday 27 July 2018 to discuss the draft designs for the Emily Street foreshore protection works. The following information is a summary of the meeting discussion and information:

    Council constructed demonstration foreshore protection works at the end of Emily Street in October 2015. Council has secured grant funding to undertake another demonstration project extending east of the existing works. The works will address current erosion and protect the foreshore in accordance with the Marks Point and Belmont South Local Adaptation Plan, while supporting ecological values.

    The draft designs take into account community comments and concerns as follows:

    • We heard your concerns about the height of the existing Emily Street demonstration project. For this project, it is proposed to construct the next stage of the demonstration works at the reduced height of 0.75m AHD compared to 1.25m AHD for the existing works.

    • We heard that the community want access to the Lake for recreation. The draft designs show staggered sandstone rocks along the foreshore with sandy, ramped access points in between. These will be wide enough to move small watercraft in and out of the Lake, while also allowing stormwater to drain to the Lake. The design should also assist seaweed wrack to breakdown.

    • We heard that the existing Emily Street foreshore works are too big and the garden beds are untidy. It is proposed to remove some of the garden beds from the existing Emily Street foreshore protection works. Rocks will be reused in the new works. However, the flat rocks around the street sign at the end of Village Bay Close will be retained as vehicle barriers. You told us that the rocks are preferable to bollards and that, because they are flat, they make great seats.

    • We heard that you do not want cobblestone. We will not use cobblestone on the foreshore for this project and some of the existing cobblestone will be reused on site as drainage behind the sandstone.

    • We heard that you prefer flat rocks because they reduce trip hazards, provide places to sit, and are more attractive. The proposed works will avoid rocks that protrude above the new 0.75m ground level of the foreshore. Preference will be given to the use of flat rocks.

    • We heard that you prefer lower plant species. It is proposed to trial the use of native saltmarsh species for landscaping. These species are low lying, so they will not block lake views, but will help to stabilise the banks and provide intertidal habitat. This includes replanting the existing works with saltmarsh species.

    Council staff appreciate the community input received for the designs. The designs will now be finalised and construction of the works is scheduled for the 2018-2019 financial year, subject to necessary approvals and permits.

    As mentioned during the onsite meeting, we welcome your cooperation in monitoring the performance of the works when constructed. Please provide any photos and / or feedback to council@lakemac.nsw.gov.au.



  • Foreshore Assessment of Shoreline Change and the Impact of Waves on Lake Macquarie

    The Foreshore Assessment of Shoreline Change and the Impact of Waves on Lake Macquarie study presents an assessment of the recession, and run-up and overtopping hazard at four estuarine foreshore localities across Lake Macquarie, with Marks Point/Belmont South forming the primary study location.

    The study also provides a discussion on the geomorphology and coastal processes at each location. The recession hazard has been assessed at a first pass level by applying a slight variation of Lake Macquarie Council’s ‘eShorance’ methodology for a range of sea level scenarios, with this output in the form recession hazard maps.

The recession hazard has been assessed at a first pass level by applying a slight variation of Lake Macquarie Council’s ‘eShorance’ methodology for a range of sea level scenarios, with this output in the form recession hazard maps.

    A necessary initial step in preparing adaptation plans is determining the potential extent or severity of the hazards which will change the nature of the Lake’s fringes. The recent floodplain management process of the Lake Macquarie waterway (WMA Water, 2012a, WMA Water, 2012b) derived the design depths and extents of extreme flooding within Lake Macquarie. However, changes around the foreshores are not limited to extreme flood levels. Other processes which require further consideration are:
    • enhanced foreshore flooding due to the additional impact of wind waves resulting in run-up and overtopping of the foreshore above the inundation water level. Some limited analysis of run-up is available in (WMA Water, 2012b), but more detail is necessary at the local scale to enable effective planning; and
    • the response (typically recession) of the unconsolidated foreshore to sea level rise.
    The aim of the present study was to develop a methodology for analysing these hazards then demonstrate its application to the Belmont South Marks Point Local Adaptation Plan.

    Appendix C of the report presents an Overtopping Design Study for Marks Point and Belmont South Shores in which overtopping rates for Marks Point to Belmont South shorelines (i.e. the primary study site) have been estimated for range scenarios to determine the ideal crest elevation for three typical shoreline protection designs used on Lake Macquarie’s foreshore.

    If you would like more information on the report or how it relates to the Marks Point and Belmont South Local Adaptation Plan please contact the project team at council@lakemac.com.au or through "who's listening" in the right navigation panel.

    Council’s Manager Integrated Planning, Sharon Pope said the award-winning process saw Council collaborate with local residents over three years to produce a long-term strategy and 10-year Action Plan to help manage the effects of future sea level rise on their communities.

    “We are now working alongside local residents and key stakeholders to implement the adaptation plan. Council recently passed changes to development controls, including building heights, filling and adaptable housing,” Ms Pope said.

    “We also completed foreshore protection works in Village Bay Close that allowed for future lake level rises, and have completed a model of the drainage system in the area, so we can assess what would occur if we alter drains or fill land in different locations.”

    The Marks Point and Belmont South Local Adaptation Plan is a leading model for climate change adaptation and is included as one of several ‘best practice’ case studies in the Federal Government’s online coastal planning guide, CoastAdapt.

    “The plan allows people to live in and enjoy these areas, even as sea and lake levels continue to rise. Council is currently working with residents of Pelican and Blacksmiths to develop a similar plan, and over the coming years Council will continue to develop plans to help manage sea level rise in all low-lying lakeside communities of Lake Macquarie City.”

    Flood modelling is one tool Council, the community and other stakeholders can use to plan for low-lying places subject to flooding, ineffective drainage and sea level rise over time.

    Flood modelling can be used to simulate the benefits and impacts of different flood mitigation and adaptation options on the community and the environment, such as filling land, raising the floor levels of houses and designing drains differently.
