Pelican and Blacksmiths: Planning for Future Flood and Coastal Risks

Planning for the future

Living by the coast and lake is a great lifestyle, and it is important that we manage this dynamic environment where sea and lake levels are gradually rising. Decisions we make now can have lasting impacts. New roads, drains and homes built today will still be around in fifty to one hundred years, so we have to plan for the future now.

Sea levels are rising gradually at a rate of around 2.6mm per year in the lake and off the coast of NSW. Based on the best available information it is expected that mean sea level will rise 0.4 metres above 1990 levels by 2050 and 0.9 metres by 2100. This means the rate of sea level rise is expected to accelerate, but it also allows us to have time to plan and prepare now.

Lake Macquarie City Council continues to meet with residents to listen and talk about opportunities for the community to help plan for the future of the area.

    Crowdsourcing concept to track Blacksmiths shifting sands

    An innovative new concept is set to harness the power of crowdsourcing to track the ever-changing shoreline of Blacksmiths Beach in Lake Macquarie.

    Known as CoastSnap, the initiative is based on a simple premise: install a mobile phone cradle at a key point along the Swansea Channel break wall where people can place their phones and take a scenic photo of the sweeping coastline to the north.

    Photos can then be uploaded to the CoastSnap database via email or social media, where they are compiled to gradually create a time-lapse movie. The first...

    Crowdsourcing concept to track Blacksmiths shifting sands

    An innovative new concept is set to harness the power of crowdsourcing to track the ever-changing shoreline of Blacksmiths Beach in Lake Macquarie.

    Known as CoastSnap, the initiative is based on a simple premise: install a mobile phone cradle at a key point along the Swansea Channel break wall where people can place their phones and take a scenic photo of the sweeping coastline to the north.

    Photos can then be uploaded to the CoastSnap database via email or social media, where they are compiled to gradually create a time-lapse movie. The first output video can be viewed HERE.

    Lake Macquarie City Council Environmental Systems Manager Brad Sutton said that over time, the images would reveal how the shoreline changed at Blacksmiths Beach, and how that change was affected by the movement of sand.

    “Because the photos are all taken from exactly the same spot, we can get quite a precise measurement of the width of the beach, the shoreline and how it moves,” Mr Sutton said.

    “The shape, location and nature of Blacksmiths Beach make it susceptible to shifting sands and shoreline changes. CoastSnap will help us better understand these processes and contributing factors.”

    Researchers from the University of NSW and the NSW Office of Environment and Heritage will review the data to record short and long-term beach erosion and recovery.

    A pilot project has already proven successful at Manly and Narrabeen Beaches in Sydney.

    Mr Sutton urged people visiting the break wall to make use of the CoastSnap cradle and contribute to the project.

    “It’s simple, quick and fun, and there is a step by step guide next to the cradle explaining exactly what to do,” Mr Sutton said.

    The Bureau of Meteorology website details the 2018 and 2019 tide charts for Swansea and other measuring stations.

    Want to know more? The Lake Macquarie coastline and Swansea Channel typically experiences annual king tides during December and January and again in June and July. A king tide is a naturally occurring extreme tidal event and a good preview for what sea level rise may look like in the future.

    View the new tides and tidal inundation fact sheet for planning for future flood risks for more information on tides, inundation and king tides.

    Tips for our community during a king tide:

    • Avoid driving through areas that are experiencing tidal inundation and stay out of the water. Remember, salt water can cause corrosion;
    • Continue to monitor tidal events in your local area; and
    • Get involved in adaptation planning with Lake Macquarie City Council. We currently have adaptation plans underway for Swansea, Pelican and Blacksmiths, and Marks Point and Belmont South.

    For further information on king tides, visit the Witness King Tides project by Green Cross Australia at witnesskingtides.org or contact the Local Adaption Planning team on 02 4921 0333. Please note Council will be closed from 12pm Monday 24 December 2018 until Wednesday 2 January 2019.

    Please visit Council online at lakemac.com.au/city/emergencies or NSW State Emergency Service at ses.nsw.gov.au for information on safety during flood and tidal inundation events.

  • Community Group working tirelessly to progress the Pelican Blacksmiths Local adaptation plan to final stage.

    Late in 2016, a small group of dedicated residents joined with Council to start developing the Pelican Blacksmiths Local Adaptation Plan. Since that time, the Pelican Blacksmiths Community Working Group has met more than 30 times and spent countless hours helping their community to develop a plan for potential future sea and lake level rise.

    The Plan has been designed to address current and future inundation of land and protect assets from sea level rise, higher tides, beach erosion and higher flood levels. Local adaptation plans are created specifically for the local area. It’s not a one size fits all...

    Late in 2016, a small group of dedicated residents joined with Council to start developing the Pelican Blacksmiths Local Adaptation Plan. Since that time, the Pelican Blacksmiths Community Working Group has met more than 30 times and spent countless hours helping their community to develop a plan for potential future sea and lake level rise.

    The Plan has been designed to address current and future inundation of land and protect assets from sea level rise, higher tides, beach erosion and higher flood levels. Local adaptation plans are created specifically for the local area. It’s not a one size fits all approach and although we learn from previous experience and domestic and international examples, the plan must be custom built to address the unique environmental landscape of the local area. This could not have been achieved without the dedication and commitment of the Community Working Group.

    Together, with input from the local community, the Group identified hazards in their local area that needed to be addressed in the plan, including ongoing sea level rise, higher flood levels, higher ocean tides, landward movement of the sand dunes, dune over-topping from wave run-up and storm surge and channel evolution (movement of the channel landward).

    The agreed Plan objective was to adapt Pelican and Blacksmiths to the expected effects of sea level rise, in accordance with the principles of ecologically sustainable development, so that the community, economy and environment become more resilient.

    One of the key successes of the Group was the development of measuring criteria to assess the adaptation options that are feasible and best meet the needs of the community, they include:

    • Does the adaptation option agree with our objective?

    • Will it work technically (does it manage the hazard in line with our objective)?

    • How easy is it to adapt over time? How might it affect other options?

    • Will it harm the environment and are impacts manageable?

    • Does it maintain community well-being (health, safety, financial, business and leisure)?

    • Will costs outweigh benefits?

    • Do we need additional info or advice from experts?

    • When is it needed / best time to implement?

    • Who is responsible? Who pays?

    After assessing the adaptation options from the community and further research, the Groupidentified a short-list of recommended adaptation options for unique precincts in the study and planning area. They proposed a timeframe or trigger for when it was best to implement the recommended adaptation options for each precinct.

    At a community workshop in April, Council and a number of the Group’s members presented these precincts to the wider community and key project stakeholders for feedback and further ideas. More than 20 community members attended to participate in this process and progress the plan.

    The Group has now completed a further review of the precincts, hazards and adaptation options, which are presented in the following documents:

    Precinct Planning Adaptation Concepts for Pelican Blacksmiths LAP – this booklet is a progress report on the Plan and explores the recommended precincts in more detail.

    Review of Precinct Planning Adaptation Concepts for Pelican Blacksmiths – this report examines the secondary and other available adaptation options for each precinct and provides assessment for each option.

    This work by the Group and Council will help inform the probabilistic hazard assessment for Pelican, Blacksmiths and Swansea that is currently being carried out by Salients Pty Ltd and the University of Queensland. Information on the probabilistic hazard assessment and the proposed cost benefit analysis will be available later this year.

    The Group has done an outstanding job in identifying and reviewing hazards; assessing options proposed by the community and developing the precinct concepts for use in the next stages of the planning process.

    Following the probabilistic hazard assessment and cost benefit assessment, the Group and Council will commence Phase D, in which the draft Local Adaptation Plan will be placed on public exhibition for public review then recommended to Council for adoption and implementation of the Plan.
