Sand Management Working Group

The Sand Management Working Group was established in November 2019.

The group’s purpose is to ensure a collaborative approach and peer-to-peer learning in tackling sand management issues faced by councils in Sydney such as beach erosion and accretion on coastal and estuarine beaches. The group comprises member councils with an interest in sand management including Sutherland Shire, Bayside and Northern Beaches councils and Woollahra Municipal Council. It also includes key representatives from Department of Planning, Industry and Environment, National Parks and Wildlife Service (NPWS) as well as industry and academic representatives. Meetings are held quarterly and include expert presentations and project presentations and updates from member councils.

Sand Management, in particular beach nourishment, has been recognised as a potential adaptive option to offset the adverse impacts of seal level rise and increasing storm intensity on coastal assets including the retention of public beaches. (Gordon, 2009 ‘The Potential for Offshore Sand Sources to Offset Climate Change Impacts on Sydney’s Beaches’). The potential devastating impacts are evident from the 2016 ‘D Day Storm’ which moved 410,000m3 of sand from the Collaroy-Narrabeen beach alone during this time. Several other councils are also experiencing beach erosion and, in some areas, unwanted beach accretion which also has an impact on private and public assets. Short term and long term impacts are considered in both local and regional contexts and opportunities for broad scale regional beach nourishment programs are explored.

To date, presentations have been provided by representatives from DPIE, NPWS, University of New South Wales, Geological Survey of NSW, MidCoast Council, Hunter & Central Coast Development Corporation and all participating councils on the Sand Management Working Group. All presentations have been recorded and are available for members in the ‘Members Area’ of the SCCG website.

A copy of the Terms of Reference is also available for members in the ‘Members Area’.

Greater Sydney Harbour Coastal Management Program

Watch our education video to find out more about the Greater Sydney Harbour Coastal Management Program (GSHCMP) and how it can help improve catchment and waterway health for our iconic Harbour.

 

Project Summary

Twenty councils within the Greater Sydney Harbour catchment are collaborating with state agencies to develop a whole-of-system Coastal Management Program for Greater Sydney Harbour. The SCCG is project managing the delivery of this CMP.

Greater Sydney Harbour Coastal Management Program Stage 1 Scoping Study identified urban stormwater discharge as a high priority threat to environmental and public health.

The Sydney Harbour Water Quality Improvement Plan has also been completed and provides a strong base for the development of the GSHCMP.

To assess threats posed by pollutants being carried into Harbour waters, a Stage 2 investigation will determine risks across all catchments feeding the Harbour and steps needed to mitigate those risks. The aim is to provide for coordinated action by councils, in partnership with state agencies and the community, to facilitate integrated waterway health management for the entire Greater Sydney Harbour system. This Stage 2 investigation will bring together available information on urban stormwater and apply existing tools (such as the Risk Based Framework) in a coordinated way, and enable individual councils working with State Agencies to develop projects/actions for consideration in Stage 3. The investigation will also involve community and stakeholder engagement.

Purpose of a Coastal Management Program  

Under the Coastal Management Act 2016 (CM Act) councils may prepare Coastal Management Programs (CMPs) which set out the long-term strategy for the coordinated management of the coast, with a focus on achieving the objects and objectives of the CM Act.

CMPs identify coastal management issues in the area, the actions required to address these issues, and how and when those actions will be implemented. They detail costs and proposed cost-sharing arrangements and other viable funding mechanisms.

The CM Act (and other relevant legislation) establishes specific roles and responsibilities for relevant Ministers, the NSW Coastal Council, public authorities and local councils, as well as providing opportunities for communities to participate when preparing and implementing a CMP.

The importance of the Greater Sydney Harbour 

Greater Sydney Harbour is one of the world’s greatest harbours and as such is a state, national and global asset. It stretches from its upper tidal limits on the Parramatta River downstream to the ocean entrance between North and South Head. Its catchments are the home of 3.07 million people (projected to go to 4.35 million by 2041) and the region is responsible for around 25% of the nation’s GDP[1].

Greater Sydney Harbour is a magnet for tourists the world over and a source of great ecological diversity. Its waters are threatened by possible adverse impacts of population growth and development and potential impacts of climate change including sea-level rise and high magnitude catchment runoff.

At the centre of Australia’s largest city, the harbour is subject to intense human activity which presents coastal managers with many challenges. Understandably, developing and delivering a whole-of-catchment CMP will be a complex task with the project team currently working with 33 stakeholders to plan and deliver the GSHCMP. Buy-in and participation by all levels of government and the community is imperative to achieving a strategic and coordinated management framework for the Harbour.

The Sydney Coastal Councils Group is the project manager for the GSHCMP. It will be whole-of-catchment and encompass Sydney Harbour tidal waterways and its catchment lands.

These conceptual models show the impacts of stormwater discharge into Greater Sydney Harbour under both wet and dry weather conditions. The models were developed by Sydney Water in partnership with the SCCG, PRCG and DPIE project team.

 

The importance of working together

A single, whole-of-system Coastal Management Program is needed to facilitate coordinated and integrated management of Australia’s most iconic and important waterway.

Local councils have a central role in managing the coast. The Sydney Coastal Councils Group promotes collaboration between member councils on environmental issues relating to the urban coastal and estuarine environment. We represent nearly 1.3 million Sydneysiders with six councils adjacent to Sydney marine and estuarine environments and associated waterways.

There are a host of benefits to working together in a holistic and integrated way as part of the Sydney Coastal Councils Group – improved environmental outcomes, improved capacity to address strategic and harbour-wide issues and interest, better communication, advocacy and promotion and efficiency savings to name a few.

Please contact SCCG if you’d like to join the many benefits of being a member council.
