The program funded 18 projects in the implementation stream with $1,688,733; 1 project from the reserve list with $122,310; and to date, 13 projects in the planning stream with $725,000.
Ballina Shire Council
This project will undertake:
- Dredging of 2 areas within the main section of Shaws Bay to address long-term sedimentation and potential for reduction in tidal circulation.
- Utilisation of dredged sand for the nourishment of numerous beaches around Shaws Bay for the purposes of erosion control, foreshore revegetation, public access and amenity.
- Establishment of an ecological protection area, with creation of a new coastal saltmarsh and expansion of an adjoining stand of coastal cypress pine forest.
- Creation of a saltmarsh/mangrove boardwalk to link segments of the shared pathway circling Shaws Bay.
- Repurposing of an existing picnic pavilion with educational signage.
- Monitoring (hydrographic survey, saltmarsh establishment success, water quality).
Bega Valley Shire Council
This project seeks to restore the only remaining cleared riparian area on the lower Bega River Estuary. The proposed works will see the revegetation and stabilisation of a public reserve. This area was previously farmland used originally as a dairy and in recent years for beef cattle grazing. Due to unrestricted stock access and human visitation by campers and boaters along the river, the riparian zone is currently in poor condition.
This project seeks to rehabilitate 700 metres of estuary foreshore with a focus on weed control, bank stabilisation and revegetation.
A scoping study will be prepared for the Bega Valley local government area, which covers 225 kilometres of coastline and 29 estuaries. This will be the first step in preparing coastal management programs to guide future management of the coast and estuaries of the Bega Valley. The scoping study will review current management, identify issues, determine what studies are needed to fill knowledge gaps, undertake a risk assessment to prioritise threats and prepare a forward program for preparing coastal management programs.
Pambula Lake possesses significant ecological, recreational and socioeconomic values, all of which are reliant on good water quality and a healthy ecosystem. Key threats to the health of Pambula Lake are bank erosion, riparian vegetation degradation, presence of weeds, pollution inputs from agricultural land and insufficient stormwater drainage.
This project will provide a detailed assessment and prioritised list of specific locations for remediation works. On-ground works including habitat restoration, erosion reduction and management of pollution sources will be implemented at the top 10 priority sites.
Bellingen Shire Council
This project will implement actions identified in the Dalhousie Creek entrance management strategy. Dalhousie Creek, an intermittently closed and open lagoon at Hungry Head, Urunga is a very popular patrolled beach/lagoon precinct used by residents and tourists. Storms have caused significant erosion of the foreshore dunes and this has impeded the surf life saving club from safely patrolling the beach and users accessing the beach.
Through beach scraping, beach nourishment and dune management works, this project aims to mitigate immediate coastal erosion risks, reduce exposure to coastal hazards and improve resilience of the foreshore to impacts of climate change.
Central Coast Council
The open coastline of Central Coast extends approximately 80 kilometres from Budgewoi Beach in the north to Patonga in the south. Historically, coastal processes have threatened sections of this coastline and caused damage to public assets and impacted upon recreational amenity. These issues are likely to be intensified as a result of climate change and projected sea level rise.
Currently, Council are managing the open coastlines and lagoons through a number of management plans. This project will prepare a scoping study to align with the NSW coastal management framework. The primary purpose of this scoping study is to review progress that has been made in managing issues in coastal areas, develop a shared understanding of the current situation and identify the focus for a future coastal management program.
Clarence Valley Council
The Brooms Head Beach and Lake Cokora coastal zone management plan recommended extension of the foreshore reserve revetment at the north end of Brooms Head reserve to the southern bridge abutment, to ensure protection of public assets. This project will prepare a detailed design and environmental impact assessment. The design will allow for public foreshore access and stormwater management.
The Wooli Beach coastal zone management plan identified a beach nourishment scheme as being the key high priority action. Wooli Beach has a long history of coastal recession and the village of Wooli is at risk from coastal erosion. This project will complete a detailed design and environmental assessment for a beach nourishment scheme for the purposes of reducing current and future hazards/risks from coastal erosion and recession.
Coffs Harbour City Council
The scoping studies for Arrawarra, Corindi and Pipe Clay estuaries recommend that Council proceed with the development of the coastal management program (CMP). It is recommended that this be done through one joint CMP for the 3 estuaries and catchments, to gain efficiencies and to set a plan for strategically managing the estuaries into the future.
Willis, Woolgoolga, Darkum and Hearnes estuaries all have existing coastal zone management plans (CZMP's) prepared under the repealed Coastal Protection Act (1979). Under the new Coastal Management Act (2016), Council is required to update its existing plans into coastal management programs (CMPs).
This project will develop a scoping study, which sets a forward direction for a future CMP for Willis, Woolgoolga, Darkum and Hearnes estuaries.
Hunters Hill Council
This project will undertake 3 hectares of restoration works to improve ecological connectivity between Bushcare sites, restore endangered ecological communities, improve native fauna habitat and increase the resilience of these communities, which will then have a greater capacity to survive rising sea levels as a result of climate change.
Kempsey Shire Council
Implementation of management action 11 – Kempsey coastal zone management plan – South West Rocks foreshore upgrade
This project will replace existing (failed) foreshore erosion works with a 60-metre-long 'stepped' retaining wall constructed from large sandstone blocks to remediate foreshore instability and address erosion. This work will reduce public safety risks resulting from coastal process events and further damage to public infrastructure.
This project will fund additional work recommended from the scoping study. Sea level rise is anticipated to expose low-lying coastal areas within the Kempsey Shire to increasing coastal inundation impacts. The Macleay River, Killick Creek and Korogoro Creek scoping studies (2019) recommended, that:
- a tidal inundation study be undertaken to specifically model and map permanent tidal water levels within the estuaries and adjacent coastal landscapes
- coastal vulnerability area mapping is produced for the estuaries to enhance Council's capacity and knowledge to prepare and adapt to climate change/sea level rise scenarios and facilitate progression towards development of a combined coastal management program (CMP) for the 3 estuaries.
The Saltwater Creek and lagoon estuary is a principal feature and important asset to the local economy, environmental and social fabric. In recognition of the estuarine values, Kempsey Shire Council is committed to preparing a coastal management program (CMP) for Saltwater Creek and lagoon estuary.
This project will deliver stage one – a scoping study, that will form the first step of a Saltwater Creek estuary CMP, setting out long-term strategies for the coordinated management of land within the coastal zone.
Lake Macquarie City Council
This project involves the planting of 49,000 endemic coastal plants across 5 beaches. These areas are currently in a degraded state, the revegetation of these sites will significantly increase resilience from coastal processes and new weed incursions. This project will increase storm event resilience and the ecological value of the dune fields.
This project aims to restore degraded foreshore environments, which are contributing sediment into the lake via foreshore erosion, and to rehabilitate littoral vegetation to increase the buffering capacity of foreshores to treat stormwater runoff before it enters the lake.
This project will rehabilitate selected wetlands to improve the conditions and coverage of saltmarsh communities, which are vital in maintaining nursery areas for fish and prawns and habitat for shorebirds. Work to increase the coverage of saltmarsh will aim to re-establish saltmarsh, which has been reduced by up to 80%.
Nambucca Shire Council
This project will maintain and upgrade the outer revetment wall (seawall) at Scotts Head headland. This seawall is showing signs of age and failure and the proposed improvements are necessary to protect public infrastructure and open space located behind the wall.
Newcastle City Council
This project will conduct dune management and revegetation at Stockton Beach, to assist in regenerating the degraded dune system and assist in managing erosion in the area. The revegetation works will also provide amenity to the southern part of the beach, which is the most frequently used part of Stockton Beach.
Dune management and revegetation will also occur at Bar Beach, to address an area vulnerable to erosion. This will provide amenity for users of the beach area and Bathers Way coastal walk, which is elevated above the dune system.
This project involves the construction of 2 formal beach accessways to Stockton Beach at Griffith Avenue and Dalby Oval. The 2 accessways will provide appropriately managed entrance points to Stockton Beach and facilitate closure of formal and informal accessways that have resulted in erosion of the dune system. The project will also include the reconstruction of a beach access point at Stockton break wall that is used by the local surf life saving club for launching of equipment and vehicle access.
This project will monitor Newcastle coastal cliff lines via unmanned aircraft vehicle (UAV) to detect any change in the cliff face, potential rock falls or stability issues that may require management. Monitoring by UAV at a high resolution will allow Council to proactively manage risks to public safety from cliff stability hazards, particularly in association with the iconic Bathers Way coastal walk where it passes along or near cliff lines or headlands.
Northern Beaches Council
This project aims to improve Council preparedness and response to coastal storms through the preparation of a coastal zone emergency action subplan (CZEAS) for the Northern Beaches.
The CZEAS will outline the roles and responsibilities of Northern Beaches Council and other public authorities in response to emergencies immediately preceding or during periods of beach erosion, coastal inundation and cliff instability that occur through storm activity or an extreme or irregular event.
This project will develop a scoping study for Northern Beaches open coast and lagoons, as the first step towards development of coastal management programs (CMPs). A review of current coastal management arrangements will determine gaps, develop the scope and priorities.
This scoping study will cover; strategic context, CMP scope, first-pass risk assessment, a stakeholder and community engagement strategy, preliminary business case, studies needed for stages 2 and 3 and a time frame and cost for moving forward to prepare one or more CMP.
Port Stephens Council
Sand nourishment Corlette – priority 1 of Sandy Point/Conroy Park foreshore coastal zone management plan
Corlette Beach is subject to significant swell-driven, long-shore sediment transport from east to west, resulting in progressive erosion along the western side of Sandy Point and in front of Conroy Park and accumulation of sand east of The Anchorage breakwater. The coastal zone management plan identifies sand nourishment as the number one priority for the study area and identified the work as necessary to address the high degree of erosion immediately in front of and to the east of Conroy Park.
This project involves moving sand from precinct 1 (estimate 16,400 tonnes) and depositing it into precincts 2 and 3. This will restore beach width fronting Conroy Park and allow the proper operation of stormwater outlets adjacent to The Anchorage.
Rous County Council
Rous County Council will conduct water quality monitoring of key locations in the lower Richmond River to provide timely notice of potential negative water quality events, to assist stakeholders with water quality information and to provide important input into broader ecohealth assessment. Rous County Council water quality monitoring will include automated continuous data loggers at 5 sites and weekly manual sampling at 6 sites.
Rous County Council will coordinate the delivery of a scoping study for the Richmond River, in partnership with all local government authorities within the catchment. The scoping study will outline the proposed pathway for preparing a coastal management program (CMP). This will eventually form part of a whole-of-catchment Richmond River CMP to replace the existing Richmond River coastal zone management plan (CZMP).
Shoalhaven City Council
The Shoalhaven River estuary has complex social and environmental management challenges around entrance management, oyster production, recreational use, farming practices and acid sulfate soil. This project will update the existing estuary management plan to align with the Coastal Management Act 2016 to guide future management of this important estuary.
This project will develop a coastal management program for Lake Conjola, with the aim of maintaining and, where possible, improving the lakes' environmental condition and health. The coastal management program will provide Council with a plan to guide future management.
This project will deliver:
- Improved condition and resilience of 175 hectares of coastal endangered ecological communities.
- Support and improve the capacity of 13 volunteer Bushcare groups to protect, restore and rehabilitate coastal endangered ecological communities.
- Raised community awareness of the importance of coastal vegetation in protecting foreshore and estuarine landscapes.
Wollongong City Council
This project will protect and enhance the endangered ecological communities in the Bellambi Gully Creek estuary. The work will concentrate on the riparian areas along Bellambi Gully Creek and will involve weed control and revegetation across 4.6 hectares. This project will also promote community involvement in weeding and planting works through Council's Bushcare program.
Working together, Wollongong and Shellharbour City Councils will restore ecological function to key saltmarsh wetland and swamp oak communities around Lake Illawarra by eradicating large quantities of invasive weeds and reinstating endemic vegetation. The work will occur at 3 sites:
- Primbee foreshore
- Heritage Park at Windang
- Horsley Creek in Oak Flats.
The Perkins dune system is a 4-kilometre sand spit from Port Kembla to Windang and is one of the only examples of original remnant dune system along the Wollongong coast. This project will concentrate on weed control and revegetation across 6.5 hectares of dunes, to improve the condition and resilience of these important remnant vegetation communities.
Funding for these projects came from the NSW Government Coast and Estuary Management Program.
The program funded 19 projects in the implementation stream with $2,666,175; 4 projects from the reserve list with $260,750; 1 significant open coastal hazard project received $5,505,000; and 21 projects in the planning stream with $1,671,100.
Ballina Shire Council
This project will undertake riverbank stabilisation and rehabilitation along Emigrant Creek from Tintenbar downstream to the intersection of Old Bangalow Road and Tamarind Drive (just north of Ballina). The riparian zone is currently either bare of vegetation or dominated by weed infestation. In some areas, the banks are badly eroded and as a result the creek has a very high sediment load. Weeds will be killed and/or removed, endemic plant species planted, and erosion and banks stabilised to prevent further erosion.
The Richmond River governance and funding project will develop a governance model to substantially improve strategic investment towards improving the health of the Richmond River. A new governance framework is necessary to mitigate the ongoing degradation of the river system and to improve environmental, economic, and social opportunities for current and future generations. The model will consider what resources are required, how these can be sustained into the future, and how they would be utilised efficiently across the catchment for maximum effect.
In 1997 Council completed the restoration of Lady Robinsons Beach between Sandringham Bay and Florence Street, Ramsgate. The project involved the construction of 8 rock and concrete panelled groynes and the placement of 151,000 cubic metres of sand between the compartments. In the 20 years since the above-mentioned project was completed, erosion has continued to occur along Lady Robinsons Beach. This project will undertake beach nourishment along Lady Robinsons Beach, using sand sourced from south of Dolls Point.
The western foreshore of Botany Bay continues to be affected by beach erosion and dune degradation, caused by both natural events and man-made structures in Botany Bay. A list of works to reinstate the beach amenity, stabilise the shoreline and manage coastal hazard risks has been prepared. This project will assess the works, undertake a condition survey along the beach, prepare detailed concept designs, undertake a cost-benefit analysis and commence construction plans.
Bega Valley Shire Council
Bega Valley Shire contains roughly one-eighth of the New South Wales coastline and, while the area is known for having some of the most natural and intact coastal ecosystems in New South Wales, coastal events and human pressures require Council to actively manage these systems. This project will map issues and develop a two-year implementation plan for 19 key Council managed beach and dune environments. The rehabilitation phase will involve access consolidation, weed removal, seed collection and propagation and revegetation.
Bellingen Shire Council
This project will undertake a scoping study, the first step towards developing a coastal management program. The scoping study will review and ascertain any data gaps in the current coastal and river studies, including the certified Bellingen coastal zone management plan. The scoping study will include a strategy to engage the community and other stakeholders.
Byron Shire Council
The Byron Shire coastline has endured a long history of coastal storms and coastal erosion and has been identified as an area undergoing long-term coastal recession. To provide a strategic and robust mechanism to manage these issues, Council will commence the process of preparing a coastal management program for the Byron coastline. This project will complete 2 scoping studies which will involve the synthesis of relevant literature and studies and the identification of any additional information needs.
The Jonson Street protection works are a public asset that protects Byron Bay town centre from coastal erosion and recession. The land area adjacent to the works is widely regarded as an iconic Australian coastal location. There is an immediate threat to the structural integrity of the protection works and the integrity of the Byron Bay memorial pool, adjacent land and infrastructure. Undertaking an investigation and design of potential future works is important to ensure the most appropriate design for the location. This project is the pre-construction phase of the project, focusing on the design investigation, financial appraisal, planning and approvals.
Central Coast Council
Pearl Beach Lagoon is a small and mostly closed coastal lagoon on the New South Wales Central Coast. The lagoon is a significant local landscape feature with both ecological and aesthetic value.
The primary goal of the Pearl Beach Lagoon coastal zone management plan is to improve the health of the lagoon. This project aims to address the initial stages through the investigation and design of 3 of the management actions listed in the plan, which relate to the hydrological and sedimentary processes occurring within the lagoon.
This project will investigate the feasibility and design for a seawall and beach nourishment program for Wamberal Beach, to protect against future coastal erosion. The project will develop a design and costing package, cost-benefit analysis, benefits distribution analysis and funding model for the works. This will allow for an informed decision to be made on the implementation of a terminal protection structure and beach nourishment.
Coffs Harbour City Council
This project will provide comprehensive water quality information for the Coffs Coast and Orara catchments. It will allow Council to identify and investigate any issues and monitor trends in ecosystem health over time. A simple report card will be developed for the community and a more comprehensive technical report detailing site condition and trends for Council.
This project will integrate the risks associated with coastal hazards into the Council's existing electronic asset management system. By utilising risk notifications in the asset register, appropriate and hazard-aware project design is triggered early in the asset planning process. This allows for the delivery of community services in a way that proactively responds to coastal hazards.
Council will investigate options to repair a popular area of Coffs Creek within Park Beach Reserve in a way that rehabilitates the shoreline habitat and formalises public access to the creek and beach. A range of different designs will be explored to maintain community access and current site usage, balanced with managing ecosystem requirements.
Council will commence the process of updating existing plans for these areas into coastal management programs. The scoping study will set the direction for these plans. The Coffs Coast is an important location and planning for the future is crucial to ensure the area is managed effectively.
This project will develop a stormwater management operational plan for Coffs Creek. The plan will explore and identify strategies and designs for the maintenance and upgrade of existing stormwater infrastructure, in the context of future coastal inundation and estuary health requirements.
Eurobodalla Shire Council
This project will protect and enhance Eurobodalla’s coastal environment, by undertaking river and foreshore restoration works including weeding, revegetation and erosion control as well as implementing localised community education programs to increase community awareness and participation in environmental protection works. It will improve the condition of 656 hectares of key estuarine endangered ecological communities and high-value foreshore vegetation.
Fairfield City Council
Green Valley Creek is a tributary of Orphan School Creek (a significant tributary of Prospect Creek) which has been severely impacted and degraded by various land use changes, weed infestation, sewerage and stormwater pollution. There is also significant erosion caused by poorly built infrastructure along the creek. This project will rehabilitate 780 metres of Green Valley Creek between the Cumberland Highway and the confluence of Orphan School Creek. The proposed works will utilise a combination of environmental rehabilitation, stormwater management and landscaping works. This will ultimately reduce bed and bank erosion, improve water quality, restore native vegetation and provide greater amenity for the local community.
Georges River Council
This project will undertake a scoping study to transition the existing Georges River estuary coastal zone management plan into a coastal management program. Eight councils will work together to achieve this. A summary report and a community and stakeholder engagement plan will be developed through this project.
Hawkesbury City Council
Council will implement a local-scale water quality monitoring program for the tidal section of the Upper Hawkesbury River. Water quality and biological data will be used to assess the health and baseline condition, and for the development of biennial report cards. The monitoring program will establish baseline water quality condition for the Upper Hawkesbury River which will allow Council to assess the benefits and impacts of future rehabilitation and restoration works in the estuary.
Hunters Hill Council
This project will involve sediment and weed removal to enhance coastal saltmarsh and mangroves in Tarban Creek. Sediment and weed removal works will focus on reinstating the natural substrate as far as practical to allow for optimum tidal regimes for the saltmarsh and mangroves.
Kempsey Shire Council
Implementation of management action 12 Kempsey coastal zone management plan (CZMP) Grassy Head option C
Recent coastal processes and community usage has damaged existing beach access provisions and is impacting on coastal environmental values. This project will result in improved and safer beach access for the general community and holiday park visitors and reduced environmental impacts such as dune destabilisation and native vegetation damage.
Lake Macquarie City Council
An integrated coastal zone monitoring program will be undertaken to monitor the physical and ecological condition of key components of Lake Macquarie’s coastal zone: beach/dune morphology, aquatic health of the estuary, and ecological health of foreshore inter-tidal zones.
This project will carry out work on the stability of the bed and banks of tributary creeks of Lake Macquarie to maintain estuary health. It will improve stream health at multiple sites commencing in Crokers Creek. Crokers Creek has been highly modified by urbanisation and carries a significantly increased amount of discharge compared to natural pre-development runoff.
Lane Cove Municipal Council
This project will protect, rehabilitate and stabilise the creek bed, bank and infrastructure in 3 drainage lines that run into Gore Creek. These areas have been prioritised for the following reasons: high levels of erosion causing massive movement of sediment, and risk to existing stormwater infrastructure and sewer. These works will greatly improve the 3 drainage lines but will also improve Gore Creek and its surrounds.
This project will address issues surrounding multiple unstable pedestrian beach access points at the southern end of Blueys Beach. It will improve pedestrian safety and allow for improved ecological management of the dunes.
This project will address water quality impacts in Forster and Wallis Lake through the implementation of water sensitive urban design. The project will focus on the refurbishment of the Townsend Street constructed wetland, which receives considerable stormwater flow from 90 hectares of the surrounding catchment. The constructed wetland requires refurbishment to ensure the effective treatment of urban stormwater to minimise pollutant loads to the Wallis Lake estuary. Additional erosion control works will also be carried out including rock lining and vegetation planting to stabilise 2 large inlet channels to the wetland.
This project will undertake ecological health assessments of the Wallis Lake estuary, Smiths Lake estuary and Karuah River estuary, focusing on key ecological indicators including:
- Chlorophyll, turbidity, temperature and dissolved oxygen.
- The health and extent of seagrass and reliant sponge communities within southern Wallis Lake and Smiths Lake.
The results will be reported to the community through 2 report cards and associated engagement activities. This information will also be used to monitor progress of management actions and identifying future actions that are needed.
The Big Swamp project is a broad-acre acid sulfate soil remediation project within the Pipeclay Canal-Cattai Creek catchment, which has been identified as one of the worst acid sulfate soil hotspots in the State. The project area consists of 2000 hectares of coastal floodplain that has been extensively cleared and drained for agriculture, resulting in the significant discharge of acid runoff into the Manning River estuary. The runoff has adverse impacts on water quality, aquatic ecology, oyster production and commercial and recreational fishing.
Mid-Coast Council will undertake a cost-benefit analysis and distributional analysis to quantify the cost and the economic, social and environmental benefits, of undertaking the rehabilitation project.
This project will develop an understanding of critical processes and drivers underpinning the health of the Manning River estuary on the mid-North Coast. This will be achieved through engagement with the community, key stakeholders and public authorities to identify the purpose, preliminary vision, objectives, issues and opportunities for the Manning River estuary. It will inform future management actions to protect and enhance the environmental values of the estuary in a sustainable, practical, socially and economically viable way.
Through this project, Council will identify potential solutions to mitigate hazards on Pacific Parade and Old Bar Beach, from the passage of Racecourse Creek across Old Bar Beach. This will be accomplished through the completion of a risk management study and plan for Racecourse Creek using a revised approach to combine catchment flooding and coastal inundation flooding behaviour. This study is essential for the development of the Old Bar/Manning Point coastal management program and identifying management solutions for this dynamic section of the NSW coast.
Nambucca Shire Council
Bellwood Park, Nambucca Heads, is a valuable asset for the Nambucca Shire community which provides facilities and open space for passive recreation. This project proposes to reconstruct a failed and ineffective foreshore protection structure which is presently causing safety issues for the public.
This project will replace the existing failed geofabric beach access path with a robust design, using recycled plastic planks at a beach access path connecting the V-Wall and Shelly Beach. The project will install the planks for the length of the path, which is about 150–200 metres, to improve the popular beach walking trail linking 2 popular local spaces and tourist destinations.
Newcastle City Council
The Newcastle coastline supports a range of natural landscapes, including open sandy shores and biologically diverse rock platforms, and constructed infrastructure such as urbanised seawalls and breakwaters that support the largest commercial shipping port in New South Wales. Managing the interaction of coastal processes and hazards on future and existing infrastructure, while still protecting the natural environment and preserving the coastal lifestyle, poses real challenges.
This project will develop a coastal management program for Newcastle. The coastal management program will set long-term strategies for the coordinated management of the entire coast in the local government area.
Northern Beaches Council
The June 2016 storm demonstrated that properties along Collaroy–Narrabeen Beach are under imminent threat of damage. This requires coastal protection works to be implemented in a coordinated manner. The proposed works are identified as suitable and desirable in the coastal zone management plan for Collaroy–Narrabeen Beach and Fishermans Beach and extend a length of 1.29 kilometres from South Narrabeen Beach to Collaroy Beach. They will provide effective protection to public and private assets from coastal storms.
The project benefits include ensuring public safety and preventing risks to human life, as well as maintaining public access, amenity and use of the beach and foreshore. These works will also significantly reduce the reliance on emergency response during and after coastal storms.
Port Macquarie–Hastings Council
At present, stormwater infrastructure on Illaroo Road directs runoff to Lighthouse Beach via 2 stormwater outlets. These existing outlets pose a risk of erosion to the beach foredune and subsequent potential undermining of Illaroo Road. This project will construct new stormwater infrastructure along Illaroo Road to direct stormwater runoff to the northern end of the road and discharge to Lake Cathie, therefore, bypassing the existing outlets on Lighthouse Beach.
Shellharbour City Council
This project aims to restore dune stability by replanting blow out areas due to natural deterioration of coastal wattle. The Warilla dune system was extensively planted in the 1990s and since has had areas that have died off. This project will increase the diversity of native species planted and will target the removal of environmental weeds including asparagus fern and turkey rhubarb.
Several studies completed for Warilla Beach, highlight a need to reconstruct the beach's seawall to an appropriate engineering standard. While the seawall currently protects residential properties, infrastructure and public amenity, its future utility is uncertain.
This project will determine the feasibility and viability of management options, through a cost-benefit and distributional analysis.
The Council of the Municipality of Kiama
This project will assess the bank erosion issues along the Blue Angle Creek and develop an erosion control options assessment report. There are 2 priority areas where erosion is active which is impacting the social and environmental values of Blue Angle Creek and the Crooked River. Other areas to be looked at in the options analysis will include access points and potential future infrastructure to deal with the access ways into the creek, including the kayak launching area and potential for future fishing platforms on the bank of the creek. The preparation of an erosion control options assessment is essential for implementing works along Blue Angle Creek which will provide Council with sufficient technical and financial information to allow for future implementation of suitable erosion control recommendations.
This project will control asparagus fern and other wetland weeds impacting the estuarine wetlands at the northern end of Charles Avenue, Minnamurra. The main weed species to be dealt with include asparagus fern, cape ivy, moth vine, bridal creeper, Norfolk Island hibiscus and other incidental weeds being removed as required.
This project will develop a coastal management program to identify and address coastal hazards and vulnerabilities. It will identify management opportunities to develop locally relevant responses to issues in the areas of planning and development; infrastructure and asset management; environmental conservation; cultural heritage; and community use.
The Council of the Shire of Hornsby
This project will undertake a scoping study for the tidal waterways of the Hawkesbury River system. This study will engage with the community and set the strategy for the development of the coastal management program.
This project will cover the tidal waters of the Hawkesbury River system from the upstream area of Windsor at South Creek to the mouth of the estuary between Box Head and Barrenjoey Head in Broken Bay.
Tweed Shire Council
Tweed Shire Council will develop a coastal management program for managing the social, environmental and economic issues, and risks along its 37-kilometre coastline. This coastal management program will also set a long-term strategy for more sustainable management of the Tweed coast based on a risk management approach.
This project will prepare a scoping study to inform the preparation of a combined coastal management program for the open ocean coast of Sydney's eastern suburbs.
Woollahra, Waverley and Randwick Councils will work together to undertake this project, so they can implement a consistent and comprehensive approach to coastal management along the coastline in this area.
Wollongong City Council
Lake Illawarra is a highly valued natural resource within the Illawarra region and is immensely valuable from an ecological, social and economic perspective. The foreshore of the lake has major environmental problems, including invasive plants, fragmented remnant native vegetation and weedy drainage lines that run directly into the lake.
This project aims to restore and enhance the condition of estuarine riparian vegetation at 5 highly degraded sites along the foreshore of Lake Illawarra. These sites all have drainage lines and creeks that feed directly into the lake and are a source of sediments and nutrients. Priority actions include primary and secondary weed control and revegetation with appropriate native species. The objective is to increase estuarine habitat condition and connectivity in heavily weed infested areas and to enhance bank stability through targeted revegetation to improve the estuary health of Lake Illawarra.
The construction of a seawall at Wollongong North Beach is identified as a priority option within Wollongong City Council's coastal zone management plan: Implementation Plan. Wollongong City Council has developed a concept design and completed a cost estimate for the construction of a new seawall. This project will undertake a cost-benefit analysis and distributional analysis to confirm if the construction of a new seawall is the most cost-effective option for protecting coastal infrastructure and natural assets at North Beach.
Funding for these projects came from the NSW Government Coast and Estuary Management Program.
The program funded 13 projects in the implementation stream with $1,071,600; 24 projects in the planning stream with $1,520,275; 2 projects from the reserve list with $47,964.50; and 1 significant open coastal hazard project received $50,000.
Ballina Shire Council
This project expands on previous works to restore the hydrological regime of Chickiba Wetland. Chickiba Creek received an ecohealth grade of D+ in 2014. The main areas of concern are the lack of riparian vegetation and the water quality in the catchment. This project involves re-establishment of habitat within Chickiba Wetland including the creation of connectivity between Chickiba Creek (tidal waters) and Chickiba Wetland for aquatic fauna. This project also includes working with and educating the local community to explain the work undertaken and their role in its maintenance.
Lake Ainsworth coastal management program
Lake Ainsworth is a popular destination for visitors and locals and is a significant natural icon in the area. A recent report into the water quality of Lake Ainsworth has indicated reasons for concern, one of the main concerns is that nutrient levels have doubled since 1995 and resulted in cyanobacteria outbreaks. This project will develop a management frameworks, including a recreational use strategy, to preserve the ecological condition of the riparian zone and lake function while also allowing for public access and use. It will also establish the impacts of climate change in this area, including sea-level rise and coastal inundation.
North Creek is a complex system with significant estuary health issues. It is a relatively unstudied estuary and there no clear understanding of processes and interactions within the study area to identify cause and effect with respect to the significant health issues. As a result of reduced estuary health, the previously robust oyster industry is no longer viable and fish populations are compromised, with a reduced range and abundance of fish present. This project will undertake the first stage of a coastal management program, a scoping study. The study will review all relevant literature, aerial photographs, water quality data and other study results to determine the issues for further investigation and the likely methodologies to pursue these investigations. The structure of the scoping study has been designed to allow the stakeholders to provide detailed input.
Siltation and shoaling within Shaws Bay underlies a number issues within the bay including poor flushing and tidal exchange, poor water quality, smothering of seagrass and shallowing of high-usage swimming areas. Dredging will help address these issues and encourage users to sections of the bay with better water quality, allow the creation of an environmental zone in the northern section and generate material for the creation of sandy beaches. This project will determine the feasibility, environmental, legislative and logistical constraints and approvals of dredging so that implementation of dredging within Shaws Bay can be undertaken in an optimal manner. This project is a key component in the long-term management of Shaws Bay.
Shaws Bay East Arm habitat stabilisation and erosion control works
This project is the first priority of the Shaw's Bay Coastal Zone Management Plan and seeks to arrest bank erosion, create shoreline habitat and improve public amenity at this increasingly popular location. The project is considered an excellent candidate to showcase effective, functional and environmentally sensitive shoreline management measures. The resulting shoreline will consist of sandy beaches with saltmarsh fringes and mangrove habitat as well as a more traditional rock wall along a shady bank which is highly consistent with the aesthetics of the location.
Lady Robinsons Beach at Cook Park Kyeemagh is located on the western foreshore of Botany Bay and contains a narrow dune strip varying in width from six metres to 15 metres. Over the last 20 years Council has been undertaking works to restore the dunes that are constantly impacted by beach erosion and windblown sand impacts from storm events in Botany Bay. These works have resulted in a stable foredune however, the backdune that is partly protected by a steel corrugated wind control fence has deteriorated resulting in a steep unmanageable bank full of weeds and exotic plants that is a hazard to pedestrians using the adjacent pathway. In order to restore this 300 metre by five metre wide section of the dunes it is proposed to remove the metal barrier fence, regrade and recondition the bank and then plant out the bank with local coastal native trees which will merge into the stable frontal dunes.
Restoring degraded wetlands of western Botany Bay
This project will implement a number of priority actions identified in Council's Natural Areas Restoration Plan for wetlands stretching from Scarborough Ponds, Monterey in the north to the Georges River in the south. These works will focus on staged terrestrial and aquatic weed removal which will improve the condition of endangered ecological communities, wetland areas and waterways, as well as habitat for the threatened grey-headed flying-fox, southern myotis and migratory birds. This project will also create opportunities for community stewardship of the natural environment through Bushcare days, community planting days and wetland tours.
Bellingen Shire Council
This project will address impacts from coastal erosion and impeded beach access at Hungry Head Surf Life Saving Club. It will assist in maintaining safe pedestrian and surf club vehicle access to Hungry Head beach and also address the impacts of informal pedestrian access through native vegetation, which have arisen as a result of the impeded access. The project involves formalise access ways, fencing, weed control and revegetation.
Coastal management program – North Byron Shire coastline
This project will prepare a coastal management program for the northern precincts of the Byron Shire coastline including the townships of South Golden Beach and New Brighton. The coastal management program will build on existing studies and management plans that have been developed for the coastline and will identify viable management responses for this area of the Byron Shire coastline.
Cooks River catchment coastal management program – stage 1 scoping study
There are 3 major issues contributing to the physical degradation of the river: high volumes of stormwater adversely impacting stream flow regimes and degrading aquatic habitats; sewer overflow into the river during intense rainfall events; and degraded physical structures i.e. banks instability and sedimentation. This project will develop a scoping study to underpin and inform the development of a coastal management program for the Cooks River catchment. Undertaking a scoping study will assist in identifying management issues and prioritise management actions.
Umina/Ocean Beach erosion management strategy
Umina/Ocean Beach is in Broken Bay at the southern end of the Central Coast local government area. The sedimentary system within Broken Bay is extremely complex manifesting in medium to long term periods of cyclical beach erosion and accretion. During extended periods of erosion, the integrity and stability of The Esplanade behind the beach is often compromised and historically this has been managed through ad hoc protection and beach scraping.
This project aims to set the direction for the long-term management of coastal hazards within this embayment in accordance with the Gosford Beaches Coastal Zone Management Plan. This project will investigate 2 aspects: nourishment of the beach utilising sand from the Ettalong Shoal offshore of Half Tide Rocks; and protection of The Esplanade between Ocean Beach Surf Life Saving Club and Koorung Street boat ramp.
Developing a river watch monitoring program for the Parramatta River: Phase 1
The Parramatta River Catchment Group, an alliance of State and local government and the community, is working to make the Parramatta River swimmable again by 2025. This project will undertake Phase one of the Parramatta River Catchment Group’s proposed river watch monitoring program, which involves initial contaminant screening at 7 proposed swimming sites along the river. Contaminants to be monitored will include heavy metals, dioxins, polynuclear aromatic hydrocarbons, polychlorinated biphenyls, surfactants and pesticides.
Parramatta River seawall audit and options investigation
There are about 8.2 kilometres of seawalls along the Parramatta River in the City of Parramatta Council area which protect public and private assets. These seawalls are in various states of repair. Council is seeking to carry out an audit of the condition of all seawalls in the Council area to inform future repair and maintenance requirements. The audit will also investigate the possibility of making existing seawalls more environmentally friendly by providing improved habitat for local aquatic life.
Beach scraping at Wooli Beach
This project will trial beach scraping on Wooli Beach, with the aim of increasing dune volume to reduce the current coastal erosion risk, for sections of the beach profile with sand volumes less than 220 cubic metres per lineal metre. Scraping works will enhance natural dune rebuilding at the time of year when deposition most commonly occurs (spring/summer), when impacts on nesting fauna will be minimised and when dune revegetation will be more successful.
Cost benefit and distribution analysis for Campbells Beach protection works
This project will undertake a cost benefit analysis and distributional analysis for possible protection works at Campbells Beach. This analysis will assist in determining and justifying the best option for long-term protection at this location. It will also identify the distribution of costs and benefits among the different parties affected by the management actions.
Prepare Moruya and Wagonga Coastal Management Program
The Moruya Estuary Management Plan and Wagonga Estuary Management Plan Review identified projects and initiatives aimed at protecting and restoring key environmental assets and social amenity. A recent review of these plans determined that most of the high priority projects have been implemented, including major erosion control works, weed control and water quality monitoring programs.
This project will develop a new plan that considers changes in land use within the catchment and community opinion on how the estuaries are currently managed. It will deliver a structured framework for stakeholders to reference in managing and monitoring these estuaries. The outcome of this project is to maintain and where possible, improve the environmental condition and health of Moruya and Wagonga estuaries.
Georges River foreshore access and improvement plan
This project will develop a Georges River foreshore access and improvement plan, including mapping of current and future coastal hazards. Coastal inundation, tidal inundation and foreshore erosion mapping will be overlayed over these hazards to consider potential locations for the enhancement of endangered ecological community habitat.
This project will also identify locations within the publicly owned foreshore suitable for enhanced recreational access and amenity, and the construction of environmentally friendly seawalls. Concept designs and costings will be produced for these improvement works.
Kempsey Shire Council

Management action 11: Kempsey Coastal Zone Management Plan – investigate and design foreshore concept plan
Kempsey Coastal Zone Management Plan identified issues associated with foreshore erosion by coastal processes and increasing risks to public safety arising from the existing foreshore protection works adjacent to the South West Rocks Surf Life Saving Club and primary community beach access location. This project will investigate possible management options and prepare design concept plans to upgrade the existing foreshore protection works to abate future coastal processes impacts and facilitate improved public usage and safety in the area.
Lake Macquarie City Council
The stability of bed and banks of tributary creeks of Lake Macquarie is an important factor that contributes to the maintenance of estuary health. Slatey Creek, Dora Creek, Stoney Creek and Wyee Creek are identified as being subject to long-term sensitivity to the combined impacts of total suspended solids, bio-available nitrogen and organic enrichment from catchment sources.
This project aims to identify and redress stream bank and bed erosion through the design and implementation of in-stream stabilisation works in conjunction with riparian habitat restoration. The use of remote sensing technology (supported with ground truthing), will be trialled for the rapid assessment of stream and habitat condition. Works will include techniques such as bed and bank control structures, rock-fillets, bush regeneration, weed management and revegetation.
Seagrass health and extent is a key issue for the management of the Lake Macquarie estuary, as seagrass is critical to the ecological function and productivity of the estuarine system. Lake Macquarie contains the third largest area of seagrass within NSW. Mapping is the most cost effective mechanism to monitor its extent. A new assessment is required to provide contemporary information to feed into Council's Estuary Health Report Card, State of the Environment Report, Integrated Planning and Reporting Framework, and NSW State-wide Monitoring Evaluation and Reporting framework, and to aid in effective estuary management.
Lake Macquarie high priority estuary foreshore stabilisation project
This project will rehabilitate selected priority foreshore areas of Lake Macquarie which have become degraded over time due to a number of factors including vegetation loss, public use of the foreshore and subsequent erosion by wind waves. These combined factors act to elevate sediment loads in the Lake, reducing water quality, whilst loss of littoral vegetation diminishes the natural processes of filtering stormwater runoff before entering the Lake. All aspects of the foreshore rehabilitation will improve the overall health of Lake Macquarie.
The Lake Macquarie native dune vegetation and enhancement project aims to engage contractors and support ‘Coast Keeper’ teams to work along the entire coastline to plant about 20,000 native dune plants, eradicate bitou bush and other transformer weeds, reshape dunes and exclude vehicles to enhance and increase dune resilience.
Pelican foreshore stabilisation – concept design options and detailed design
The Pelican foreshore contains some of New South Wales most vulnerable assets, which are at risk from coastal erosion. Ongoing erosion is currently threatening essential emergency service facilities and recreational assets and if left unchecked, will threaten residential housing. The cause of this erosion (ongoing migration of Swansea Channel) is well understood, however, this largely unprotected stretch of foreshore at Pelican will continue to claim assets unless foreshore protection works are effectively designed, costed and installed. The high vulnerability of the Pelican area to sea level rise impacts necessitates that various adaptation pathways be considered, as part of the concurrent Pelican–Blacksmiths local adaptation planning process.
This project will prepare an agreed concept design for foreshore protection works, considering coastal processes on-site. The concept designs and detailed design produced by this project will also inform a climate change adaptation plan for the Pelican-Blacksmiths area.
This project will undertake wetland rehabilitation around Lake Macquarie. The identification of priority wetlands for rehabilitation has been informed by a process that considers current biological health of the wetland, on-going maintenance and the outcomes of a recent study. Works under this grant aim to improve water quality, restore/preserve habitat values, reduce poor management practice and improve the buffering capacity of wetlands against projected sea level rise.
This project will develop a coastal management program for Old Bar and Manning Point areas. This project will undertake extensive community consultation to enhance the communities understanding of coastal process. The coastal management program will determine the future management options of these areas.
Trial interim trucking program, Winda Woppa to Jimmy’s Beach

This project involves a trucking campaigns of 5000 cubic metres of sand from the stockpile on Winda Woppa to Jimmy’s Beach.
Nambucca Shire Council
The Nambucca Heads Surf Lifesaving Club and ancillary infrastructure at Main Beach Nambucca Heads is located in a vulnerable area of the coast affected by coastal erosion processes. Council's certified Coastal Zone Management Plan prioritises actions for the immediate and urgent maintenance of the seawalls at Main Beach with an aim to maximise the life of the existing infrastructure. This project will address the area adjacent to the club facilities, driveway, public foreshore and car parking area to the north of the club and also provide a new beach access point between the carpark and the Surf Club.
This project will support Nambucca Shire Council to prepare a coastal management program. This program will review and update Councils existing plans and strategies and consolidate them into a comprehensive guide for coastal management across the Nambucca local government area.
Collaroy–Narrabeen protective works benefit distribution analysis
This project will fund the development of a distribution analysis of costs and benefits among the various parties for construction of protective works along Collaroy–Narrabeen beach. Development along Collaroy–Narrabeen beach is classified as the most at risk in New South Wales from coastal processes. This site was subjected to coastal erosion during the June 2016 East Coast Low and significant impacts occurred to private and public properties.
Port Macquarie–Hastings Council
This project involves the completion of detailed designs, reports, documents and gaining all necessary approvals for the redirection of stormwater from two existing outlets which empty directly onto Lake Cathie beach directly opposite Illaroo Road.
This project involves the development of a funding model for the construction of the Lake Cathie revetment wall and ongoing beach nourishment.
The development of a funding model will use and expand on existing cost-benefit analysis work in this area, finalise actual costs and apportion those costs to all stakeholders that benefit from construction of the revetment wall and accompanying beach nourishment.
Active coastal erosion is undermining existing stormwater infrastructure along Lighthouse Beach, between Lake Cathie and Middle Rock. The Middle Rock Road project will involve the design and reconstruction of the degraded infrastructure and locally eroded dune (including shaping/filling, revegetation and fencing) to prevent ongoing localised erosion and damage to infrastructure. The Chepana Street project will involve maintenance of a degraded stormwater outlet and locally eroded dune to prevent ongoing localised erosion and damage to infrastructure.

This project will develop a coastal management program for Port Stephens waterways, that will set clear and transparent long-term strategy for the management of land within the coastal zone.
Shoalhaven City Council
The Shoalhaven coastline (165 kilometres) has a diversity of coastal features and coastal risks. This project will consolidate information from existing plans into a new coastal management program that includes the risks, consultation outcomes and management options that have been identified over the last 5 years.
Mollymook Beach South is at high risk of coastal erosion. Following storms in the 1970s, measures were taken to protect major sewage infrastructure, rising mains and the public pathway located in front of the golf club, as well as Ocean Street and the Surf Life Saving Club. The 160-metre gabion mattress revetment and 50-metre sandstone wall were damaged by storms in 2015 and 2016 and are now reaching the end of their lives. Concept designs to repair, replace and upgrade existing coastal protection structures to protect public and private assets are available. This project involves undertaking a cost-benefit analysis and impact assessment of the preferred options.
Bate Bay Coastline Management Program
Ongoing erosion of the beaches within Bate Bay has led to a gradual degradation of the recreational beach amenity and threat to public assets. This project will develop a coastal management program that addresses issues including beach use, water use, safety, flora and fauna, water quality and the impact of adjacent development.
This coastal management program will aim to improve Council’s knowledge and understanding of the physical dynamics of the Bate Bay system and will include objectives, strategies and actions related to the medium- and longer-term preservation, maintenance, development and use of Bate Bay and its foreshores.
Minnamurra River entrance foreshore rehabilitation project
The Minnamurra River bank is affected by erosion from the ocean waves and flood tides. This project will be stabilise the areas affected by erosion with bank rocks sourced on site and imported ballast, re-battered to a more natural bank grade, jute matting and replanted with low growing native vegetation. In addition, a stormwater flow line which causes erosion issues will be stabilised.
The Coastal Management and Estuary Management Grant Programs were separate programs in 2015–16. Changes to legislative and policy framework brought about by the Coastal Management Act 2016 resulted in the 2 programs being merged into the Coastal and Estuary Grant Program after the 2015–16 funding round.
In 2015–16, 18 projects were funded under the Coastal Management Program and 30 projects were funded under the Estuary Management Program.
Bega Valley Shire Coastal Zone Management Plan
This project will complete a Bega Valley Coastal Zone Management Plan that will focus on the key locations of Bermagui Coast, Cuttagee/Murrah Coast, Tathra Coast, Merimbula Coast, Twofold Bay and Wonboyn. The plan will allow Council to effectively understand and manage coastal risks.
Bega Valley Shire Council will complete a Coastal Zone Management Plan for the Bermagui River. It is a relatively small estuary which does not have a vast range of difficult management issues, however as this is a growth area an Estuary Management Plan is required to provide the best outcomes for its management into the future.
This project will review the estuary management plans for Wallaga Lake, Merimbula and Back Lake and Lake Curalo to consider new information, data, approaches to better estuary and catchment management and to capture changing views within the community in terms of how the estuaries are managed. Council has successfully implemented a range of actions from their existing plan and this review will help prioritise future actions.
New Brighton Beach scraping works 2015 to 2017
New Brighton Beach is subject to coastal erosion and inundation, with both public infrastructure and private development located adjacent to or intersected by the immediate coastal hazard zone. The primary aim of these works is to mitigate the immediate coastal erosion and inundation threat by increasing the dune volume adjacent to public and private property and land. The works will reduce the severity of the threat that currently exists.
Clarence Valley Council
The Everlasting Swamp has been referred to as the ‘Kakadu of the South’ but extensive drainage and modification since 1928 has significantly reduced its ecological attributes. This project will provide land managers with a detailed understanding of the water, soil and ecological processes that can then be used to develop strategies that will lead to the rehabilitation of the wetland. The project will also identify any risks or obstacles that need to be addressed for this to occur.
This project will undertake geotechnical assessment of strata and review the coastal hazard lines for the coastal hotspot. Data will be used to assist implementation of actions in the Brooms Head Beach and Lake Cakora Coastal Zone Management Plan. The Brooms Head is a coastal erosion hotspot. It will also inform landowners in the area who are of the view that, due to the existence of clay, rubble and other resistant material at the Lake Cakora entry, combined with distance from the ocean, the coastal hazard is not as significant as stated.
The Yamba Coastline Management Plan recommended further groundwater monitoring at Pilot Hill, Yamba. The purpose of groundwater monitoring is to enable more precise definition and possible reassessment of landslide risk. This project will review and analyse technical reports by consultants, daily rainfall records, groundwater data monitoring records and inclinometer measurement records taken over the past 10 years. Following the review, recommendations on actions to address all aspects of the Yamba Coastline Management Plan, stabilisation, subsurface drainage and classification of the landslide risk zones will be made.
Coffs Harbour City Council
This project will develop a Coastal Zone Management Plan (CZMP) for Bonville and Pine Creek. The CZMP will aim to preserve environmental and cultural values. The main issues relating to the creek are bank erosion, entrance management, Aboriginal heritage management and water quality. A CZMP for Bonville Creek will include the revision of existing studies, community consultation and an implementation schedule for strategic actions.

This project will conduct a geotechnical assessment at Woolgoolga Beach, Sandy Beach, Emerald Beach and Arrawarra Beach to determine the depth to bedrock in areas shown to be at extreme to high risk of erosion and recession by 2100, focusing on residential areas. Ground-truthing or field work exercises during the study shall focus on those properties found to be at immediate, high or extreme risk. The study will also identify other substrates that may provide suitable foundation capacity to withstand erosion and recession hazards.
Sydney Harbour Estuary Processes Study
This project will develop the Sydney Harbour Estuary Processes Study. The over-arching objective of the Sydney Harbour Estuary Processes Study is to assist decision-making for the prioritisation of management actions for a subsequent Sydney Harbour Estuary Management Plan. The Sydney Harbour Estuary Processes Study will provide a comprehensive report on the existing physical, chemical and biological condition of the estuary and those processes and interactions that influence the condition of the estuary, both within and external to the study area. It will also identify enhancement, development and management needs to ensure the long-term ecological sustainability of the estuary.
Eurobodalla Shire Council
This project will continue to control threats in the five major estuaries of the Eurobodalla Shire (Clyde, Tomaga, Moruya, Tuross/Coila and Wagonga estuaries). This project will expand on works already undertaken in previous stages and will commence work in a further four new sites. The project will involve undertaking weeding and revegetation works, as well as implementing localised community education programs to improve the condition of these habitats and increase the communities’ awareness and participation in environmental protection works.
This project will see the continuation of estuary health monitoring in the 6 main Eurobodalla estuaries, and the completion of up-to-date estuary health report cards that track how well each estuary is being managed over time. They will also inform the community of the current health of its estuaries. The project will also incorporate updated mapping of macrophytes in the 6 estuaries to expand on previous work.
This project will review the Tuross Coila Estuary Management Plan which was written in 2005. As Council have implemented a lot of activities from the plan, this plan review will consider proposed intensification of landuse within the catchment, and develop a new plan of management to capture changing views within the community in terms of how the estuary is managed.
Burdett Street gross pollutant trap installation
This project involves the installation of a gross pollutant trap on two stormwater pipes that discharge into Orphan School Creek. It will reduce the volume of gross pollutants, sediment and nutrient loads and contribute to enhanced water quality and estuary health in the Georges River.
Gosford City Council
The project aims to control weeds within the target wetlands. On-ground works will target Juncus acutus and Weeds of National Significance (WONS) including asparagus weeds and lantana and will be undertaken by appropriately qualified bush regeneration contractors using best practice bush regeneration techniques. In addition the project will work in partnership with the Central Coast Waterwatch program to implement a community engagement strategy. This will include activities such as water quality monitoring, workshops and field days, catchment crawls, preparation and dissemination of education materials. The engagement strategy will contribute to 4 of the 10 high priority catchment-wide management actions identified in the Coastal Zone Management Plan.
This project will involve a review of the Council’s lagoon entrance management regime so the desired environmental values are better considered and options are identified for adjusting practices to facilitate desired ecological benefit while meeting the flood mitigation imperatives. The review will be applied operationally to eight lagoon entrances across the Gosford Local Government Area.
Miles Island weed and feral pest animal control project
Miles Island is a recreationally and biologically important asset. Historical land use and modification has allowed invasion by a range of noxious and invasive weeds and there is a substantial population of foxes known on the island. This project will provide for the deployment of a coordinated and integrated suite of noxious and environmental weed and fox controls to enhance the condition, function and resilience of Miles Island. The project will also include community awareness and promotion and facilitated natural regeneration.
Greater Taree City Council
The project will address the sedimentation of the Manning River by stabilising at least one kilometre of severely eroding riverbank located on private land within the Manning River estuary in partnership with local landholders. The project will involve the implementation of a suite of best practice riverbank stabilisation techniques including rock revetment, rock fillets, stock exclusion fencing, weed management and the revegetation of the riparian zone. The project will result in an improvement in water quality and the enhancement of key fish habitat within the lower Manning River.
The Big Swamp project is a broad-acre acid sulfate soil remediation project within the Pipeclay Canal-Cattai Creek catchment. Significant discharge of acid sulfate soil products into the Manning River estuary has adverse impacts on water quality, aquatic ecology, oyster production and commercial and recreational fishing. The project proposes to acquire and remediate a further 200 hectares of land which will result in a reduction in acid sulfate soil discharge into the Manning River and an improvement in estuarine health.
Hunter Local Land Services
The project will stabilise the eroding river bank on the south arm of the Hunter River between Cobbans Creek and Ramsar Road at Kooragang Wetlands. Rock revetment will be installed to prevent further erosion of the river bank while allowing public access to the river. This stage of the work covers the construction at the next highest priority section of the site. Planting of riparian vegetation will be undertaken to restore the construction site.

Implementation of management strategies 8 and 11: Macleay River Estuary Coastal Zone Management Plan
There are issues with riverbank erosion and proliferation of spiny or sharp rush (Juncus actutus) within the lower Macleay estuary. This project aims to rehabilitate 300 metres of lower Macleay River estuary foreshore by: removing environmental weeds identified as posing a high threat to a saltmarsh endangered ecological community, reinstating foreshore stability, enhancing the riparian zone, and expanding fisheries habitat within the intertidal zone through a combination of timber/rock fillet protection works.
There is a lack of information about migratory and threatened bird species in the Macleay River estuary. This project will gather up-to-date information to help identify bird usage patterns, species richness, threats and management issues and high-conservation-value habitats in the Macleay River estuary. It will subsequently develop appropriate management outcomes to protect migratory and threatened bird species in the Macleay River estuary.
Dover Park West foreshore remediation project
This project involves the design and construction of a revetment structure to reduce ongoing erosion on a steep sediment foreshore slope in Dover Park West. This will involve reducing the existing foreshore slope, installing a sandstone rip-rap treatment on sections to increase foreshore strength while also increasing the variability of habitat on the existing, habitat poor foreshore. The revegetation of a section with riparian and saltmarsh will also be a part of this project.
Lake Macquarie City Council
This project seeks to increase dune resilience and links to coastal hazard reduction. The activities will include dune reshaping, revegetation, bitou bush eradication and pedestrian exclusion strategies (signage, fencing and access restrictions). The project supports a combined Coastal Land Managers Group and a Coast Keepers team for work along the coastline.
This project will undertake a detailed geotechnical assessment of locations identified as being at high risk from coastal cliff instability and in proximity to assets such as roads, services and homes. The assessment will prepare a fine-scale study of erodibility of geological strata, jointing and other geophysical features, mine subsidence, sea level rise, and historical slips and block falls to predict the likely extent of clifftop instability up to 2100, and recommend suitable development setbacks and planning controls.
The ecological health of the Lake Macquarie estuary is highly dependent on inflows from its catchment and tributaries. Altered hydrology from urbanisation has resulted in many of these tributaries exhibiting increased erosion, sedimentation and weed problems. This project aims to undertake stream stabilisation and riparian restoration at priority sites to enhance green corridor connectivity and reduce pressures impacting on the Lake. Works will include soft engineering solutions such as rock fillets, bed control structures, bush regeneration, weeding and planting with provenance tube stock as required.
This project will rehabilitate selected priority foreshore areas of Lake Macquarie which have become degraded over time due to a number of factors including vegetation loss, public use of the foreshore and subsequent erosion by wind and waves. These combined factors act to elevate sediment loads into the Lake, reduce water quality, whilst loss of littoral vegetation diminishes the natural processes of filtering stormwater runoff before entering the lake. The rehabilitation of degraded foreshores of Lake Macquarie will contribute to improving and maintaining the water quality of the lake.
This project will continue to undertake wetland rehabilitation across the city. The identification of priority wetlands for rehabilitation will be informed by a process that considers current biological health of the wetland, on-going maintenance and the outcomes of a recent study. These works aim to improve water quality, restore and preserve habitat values in these areas, exclude poor management practice and, as a management response, improve the buffering capacity of wetlands against projected sea level rise.
Bushland Park stormwater improvements Stage 1 – investigation and design
Poor stormwater quality, sediment and gross pollutants from the Gore Creek catchment flow into the Lane Cove River estuary damaging saltmarsh areas, reducing river water quality and threatening the critically endangered Hygrocybeae Fungi community which grows along the banks of Gore Creek in Bushland Park. This project will undertake a feasibility study to investigate the best location, environmental controls and options to install stormwater quality improvement devices and erosion works to improve stormwater quality. This feasibility study will include stormwater modelling and some geotechnical assessment.
Fairy Bower seawall remediation and protection project Manly NSW
Fairy Bower seawall forms part of a continuous seawall stretching along Manly Ocean Beach to Shelly Beach Manly. The Fairy Bower seawall is in need of upgrade to address immediate risk of failure of the toe section and to increase the height of the seawall crest to address wave overtopping. The project involves detailed design and construction work to raise the seawall crest, add a wave return parapet and provide structural support to the base of the seawall and the Manly Ocean outfall sewer contained within the seawall.
Nambucca Shire Council
This project will restore 200 metres of river bank on the Nambucca River at Macksville through bank stabilisation and erosion protection works including the construction of rock fillets, weed management and revegetation. The project will be a pilot for future treatment in similar locations along the Nambucca River and its upper catchment.
This project will provide an assessment of the health of Nambucca catchments using standardised indicators and reporting. The project will assess estuaries and freshwater river reaches using hydrology, water quality, riparian vegetation and habitat quality, and macroinvertebrate assemblages as indicators of ecosystem health in streams of the Nambucca region. This scientific information will contribute to the development of a report card system for communicating the health of the estuarine and freshwater systems in the Nambucca Local Government Area.
This project will include maintaining and upgrading seawall protection, designing and implementing stormwater improvements, beach access improvements, dune and weed management and facility improvements. The project will facilitate the long-term protection of significant community assets, ensure beach users’ safety, and assist in the protection of the local environmental attributes including coastal habitat and endangered ecological communities.
This project will include increasing the remnant size and restoring two coastal habitats at Valla Beach. The project will mitigate the long-term effects of sea level rise and climate changes on a riparian endangered ecological community (EEC). Increasing the remnant size of the coastal headland habitat adjoining an EEC will be achieved through revegetation of a significant area of coastal headland and riparian vegetation and weed management techniques.
Newcastle City Council
The Themeda Grassland Endangered Ecological Community (EEC) within King Edward Park was listed as the highest priority coastal/estuarine vegetation site in Newcastle in the recently completed Newcastle Coast and Estuary Vegetation Management Plan. In 2014/15 Council commenced works in the park to restore and protect the EEC. The proposed project will include ongoing weeding and revegetation works within the Themeda Grassland EEC to ensure that the good condition of the EEC is maintained and protected.
In 2013 the final floodgates of Ironbark Creek were opened to restore tidal inundation to Hexham Swamp. As anticipated, the inundation has led to dieback of the Swamp Oak Forest, which is slowly converting to an estuarine vegetation system. This project will undertake a site investigation to determine what actions Council needs to undertake to manage the conversion of the Swamp Oak Forest to an estuarine system. It is expected that the required actions may include ongoing monitoring, weeding, revegetation, bank stability and/or groundwater management works.
Pittwater Local Government Area coastal dunes restoration
The coastal dunes in the Pittwater local government area are continually degraded and destabilised as a result of invasive weed species outcompeting native species. In order to prevent or minimise future environmental and asset damage, Council proposes to upgrade or replace fencing where appropriate to delineate access pathways for the public and revegetate a large proportion of the Pittwater coastal dunes through weed eradication and plant propagation of indigenous coastal fore dune species.
Port Macquarie–Hastings Council
Port Macquarie–Hastings Council will conduct environmental restoration works on public land to protect the ecological values and resilience of this important estuarine corridor between two estuarine lakes. The area supports numerous threatened species and endangered ecological communities. The works will include weed removal, bush regeneration and vertebrate pest control.
This project includes the replacement of a section of existing dilapidated vertical retaining wall, nearshore stormwater improvements and landscaping works. A new seawall will be constructed to replace the existing dilapidated retaining wall at Flynns Beach. The wall will comprise various elements including rock rubble, vertical wall and stepped concrete. The project will also include stormwater management using water sensitive urban design principles to avoid local beach scour, reduced beach amenity and adverse impacts on bathing water quality and marine ecology from local stormwater runoff. This grant covers the replacement of the northern most section of vertical wall.
Water Quality Monitoring – Richmond River Catchment
The Richmond River and its tributaries frequently suffer from poor water quality and occasional fish kills. The floodplain contains large areas of drained acid sulfate soils causing acid drainage and Monosulfidic Black Ooze deposition and growth of exotic grasses and crops which can cause deoxygenation events (blackwater) during summer floods. This project will fund the ongoing maintenance of key data loggers, which monitor water quality, to keep them operational. Funding will also enable the continuation of real time monitoring via the website to enable a quick response to events.
Wanda to North Cronulla Dune Maintenance Plan Development
The North Cronulla to Wanda Beach dunes stretch approximately 1.5 kilometres from Dunningham Park in the south to Wanda Reserve in the north. The dunes are being impacted by vegetation loss and erosion. This sand migration is affecting adjacent infrastructure. A Dune Maintenance Plan is proposed to provide a planned and practical response to these issues.
Tweed Estuary Coastal Zone Management Plan Preparation
This project will prepare a Coastal Zone Management Plan that identifies the current condition of the estuary ecosystems in the Tweed Local Government Area. It will also present a prioritised set of policies, strategies and actions that can be implemented over 10 years to enhance ecosystem condition. It will include community input into the uses of, and future preferences for use of, the Tweed River to balance the demand for recreational access and ecosystem condition.
Bronte Seawall – Technical Assessment and Design Project
This project proposes to undertake coastal asset management at Bronte beach to ensure the Bronte seawall is structurally adequate to withstand future sea level rise and minimise the risk of collapse due to potential coastal impacts. This project will involve an independent technical assessment and design by an expert to determine the seawall's current stability and identify options to upgrade the existing infrastructure to minimise effects of future climate-related risks and related coastal hazards on the surrounding locality.
Lake Illawarra Coastal Zone Management Study and Plan
Wollongong City Council will work jointly with Shellharbour City Council to develop a Coastal Zone Management Plan for Lake Illawarra. This project will undertake an analysis of the work already undertaken, fill in the identified gaps (including a comprehensive community consultation) and produce a Coastal Zone Management Plan that will identify strategies that Wollongong and Shellharbour City Councils can use to address the management issues for the lake through an intensive stakeholder consultation process.
Reconstruction of Lyne Park Rose Bay North-east Section of the Seawall
In 2013 Woollahra Council completed the first stage of the Woollahra Coastal Zone Management Plan (CZMP) which provided a detailed investigation including all sea walls along the Woollahra foreshore area. The CZMP identified that significant lengths of Lyne Park seawall require urgent repair within two to three years. This project covers the reconstruction of the seawall.
Foreshore Rehabilitation at Noamunga Crescent, Gwandalan
Wyong Shire Council will address an area of significantly eroding lake foreshore in the suburb of Gwandalan. Sedimentation is known to deteriorate water quality, impact estuarine habitat and reduce the recreational amenity of Lake Macquarie. Rehabilitation of this site aims to address the erosion and prevent further sedimentation of Lake Macquarie from this site and improve the foreshore habitat.
The Coastal Management and Estuary Management Grant Programs were separate programs in 2014–15.
In 2014–15, 20 projects were funded under the Coastal Management Program and 44 projects were funded by the Estuary Management Program.
Ballina Shire Council
The Chickiba wetlands are of significant environmental value in a highly fragmented landscape which has suffered from wide-ranging human induced impacts. It is a designated SEPP 14 site, which is dominated by endangered ecological communities and threatened species. An action plan to rehabilitate the wetland by restoring its natural hydrology has been developed, which aims to improve the health of over eight hectares of native vegetation. Improvements to the drainage of the wetland involve the clearing and enhancement of existing drains and the installation of a weir barrier to reduce saltwater inundation. Vegetation rehabilitation works will be undertaken to compensate for native vegetation that is disturbed by the drainage works and to restore the SEPP 14 wetland to its original condition.
This project will implement the actions identified in the coastal zone management plan for the Richmond River Estuary and the Northlakes Water Quality Improvement Management Plan to improve water quality within and discharged from the lakes immediately and into the future. A partnership with Wetland Care will provide a professional, focused and friendly way for the community to be involved in managing the lakes, with council undertaking the technical works involved. This project addresses a long-standing issue for local residents and surrounding subdivisions, which is a source of poor quality water entering North Creek close to oyster leases, recreational fishing sites and popular swimming areas. On-ground works will include drain clearing to increase drainage and tidal flushing to reduce water retention times, increase water flushing and improve water quality.
Bega Valley Shire Council
The existing log and rubble retaining wall currently in place at Beach Street has aged significantly and is in a state of disrepair. The original wall was installed in the 1960s and constructed without the use of geofabric matting; thus, leaching of sediments are affecting nearby seagrass and mangrove communities. Moreover, this also has negative impacts on the local oyster industry, which is sensitive to sediment entering the waterway after rainfall. The current state of the wall also poses public safety risks and has a negative impact on the recreational use of the facility. Bega Valley Shire Council aims to remove the aged wall and replace it with a modern-designed rock wall using the same techniques carried out on previous stages of the Merimbula Lake rock wall program. This project is seen as the last step in completing the major foreshore stabilisation and erosion control works required around the front section of the lake.
This project aims to rebuild and rehabilitate the degraded dune environment at Cocora Beach in Eden. The current dune environment is dilapidated, highly erodible and contains very little native vegetation. This lack of native vegetation paired with prevailing winds has led to the development of a flat incipient dune that provides a limited storm buffer.
Bega Valley Shire Council aims to conduct a ‘Rapid Catchment Assessment’ on 3 catchments within the shire (Cuttagee Lake, Nelsons and Middle Lagoons). These intermittent closed and open lakes and lagoons (ICOLLs) possess significant ecological, recreational and socioeconomic values, all of which are reliant on good water quality. The aim of this project is to identify actual and potential threats within each catchment and provide council with recommendations based on appropriate remediation or land-use management techniques for the issues identified. Recommendations will be implemented into a catchment management plan and implemented as funding allows. This rapid visual assessment will be based on the successful Healthy Rivers Commission approach which has been showcased in other local studies conducted by Local Land Services. This approach identifies the processes and drivers in the catchment and assesses the waterway for areas of conservation potential, targeted repair and longer-term sustainable use.
Since the early 1900s Short Point has experienced high levels of visitation, as a result of this long history of intensive use, it has a range of management issues including loss of native vegetation cover, erosion, degraded beach / headland access and environmental weeds intrusion. This project will develop and implement a comprehensive restoration plan for Short Point.
Friesians & Fish - Bellinger River foodplain and estuary water quality improvement
This project aims to improve dairy effluent management practices to reduce potential impacts on water quality in the Bellingen River estuary - an important environmental, social and economic public asset. Three floodplain endangered ecological communities remain along the estuary and provide habitat for at least nine threatened species. Dairy farming is the dominant land use surrounding the estuary and in 2011, 11 dairy farms undertook a voluntary assessment of effluent management practices. This project will provide matched incentive funding for implementation of priority actions including: underground pipes for effluent irrigation field expansion to best management targets; concrete aprons and laneways to reduce sedimentation; riparian fencing and bush regeneration to reduce erosion and improve native vegetation; and a field day for industry/community education and networking. This project is a partnership between Bellingen Shire Council, Landcare and dairy farmers, with support from Local Land Services, Norco Dairy Cooperative, Urunga Anglers and oyster growers.
Coffs Harbour City Council
The development of the Arrawarra Coastal Zone Management Plan (CZMP) for Arrawarra Creek will aim to preserve environmental and cultural values. The main issues relating to the creek are bank erosion, entrance management, Aboriginal heritage management and water quality. The CZMP for Arrawarra Creek will include the assembly of existing data on the creek, community consultation, development of an Estuary Condition Study, CZMP, and an implementation schedule of strategic actions.
Key objectives for completed estuary management plans within the Coffs Harbour local government area (LGA) include estuary ecosystem and water quality health checks. Ecohealth is a cost-effective way to undertake an estuary health check - a periodic (three to four year) assessment of key ecosystem and water quality indicators. This form of assessment allows council to address any issues identified and to monitor trends in system health over time. Council initiated ecohealth in 2010. A technical report was produced by the University of New England indicating some sites are in good health and others in poor health. Since 2010 there have been changes in catchment land use. Council intends to revisit estuaries in the LGA and reassess estuarine condition. The project will also refine trigger values and produce up-to-date estuary health report cards that track how well each estuary is being managed. It will also inform the community of the current health of its estuaries.
This project will rehabilitate 200 linear metres of Woolgoolga Beach between the boat ramp and surf club. A series of beach erosion events have eroded the beach profile significantly. The project will rebuild the dunal system and rehabilitate the dune with low-lying vegetation.
Endangered Ecological Communities Conservation works across Eurobodalla Estuaries 2015
This project will involve weeding and revegetation works, as well as implementing localised community education programs to improve the condition of five major estuaries of the Eurobodalla Shire and increase community awareness and participation in environmental protection works.
Orphan School Creek Rehabilitation - Avoca Road to Cumberland Highway, Canley Heights
Orphan School Creek is the most significant tributary of Prospect Creek and the second longest creek in the Fairfield City Council area. It is also one of the city's most valuable natural assets. Like many urban creeks it has been severely impacted by increased stormwater runoff caused by land clearing and urban development. This has led to significant bed and bank erosion and weed infestation. This threatens remaining riparian vegetation and public assets. The goal of this project is to rehabilitate 800 metres of Orphan School Creek between Avoca Road and Cumberland Highway at Canley Heights. The proposed work will utilise a combination of environmental rehabilitation, stormwater management and landscaping works. This will ultimately reduce bed and bank erosion, improve water quality, restore locally native vegetation and provide greater amenity for the local community.
Great Lakes Council
The project involves the design, installation and testing of an efficient sand transfer system using terrestrial sand from the Winda Woppa spit for ongoing nourishment of the Jimmys Beach. The sand transfer system will provide for the on demand nourishment of Jimmys Beach.
Great Lakes Council will undertake an ecosystem health assessment of the Wallis Lake Estuary, focusing on key ecological indicators including chlorophyll, turbidity, temperature and dissolved oxygen, and the health and extent of seagrass and reliant sponge communities within southern Wallis Lake. This project will also include a ten-year review of the ecological health of the upper reaches of the Wallis, Myall and Karuah catchments to assess stream health.
This project addresses poor water quality, focusing on rehabilitating the most degraded part of Wallis Lake. A bio-retention trench will be constructed downstream of a stormwater drain to filter nutrients and sediments prior to entering Wallis Lake. The project also involves the investigation and assessment for refurbishment of the Townsend Street constructed wetland in Forster.
Catchment land-use has been identified as a primary threat to the ecological health of the Karuah River, Myall Lakes and wider Port Stephens estuary; in particular land management practices which contribute to high turbidity, elevated nutrient levels and poor riparian zone health. Through education and engagement, this project aims to improve land manager understanding of catchment processes and the role that land management practices play within the catchment, to facilitate positive changes to land management and long term improvement of water quality and ecological condition.
A comprehensive foreshore management plan for the crown reserve system for the foreshore area will be completed. The plan will identify priority management issues for water quality, biodiversity and cultural heritage protection in southern Wallis Lake. A comprehensive community engagement process will be undertaken to help direct the plan and make recommendations for appropriate public use of foreshore areas and adjacent lands, and future community education programs.
Greater Taree City Council
The Big Swamp rehabilitation project is a broad acre wetland remediation project within the Pipeclay Canal - Cattai Creek catchment, which is predominantly degraded agricultural land with some areas containing significant coastal wetland communities. Currently, the site discharges significant volumes of acid sulfate soil products into the Cattai Creek Manning River estuary which is highly detrimental to the estuary's health. So far, about 700 hectares of land have been acquired and rehabilitated. The project aims to rehabilitate an additional 40 hectares of the Big Swamp landscape to minimise acid sulfate discharge into the Manning River and improve estuarine health, while also achieving additional ecological benefits of a rehabilitated landscape.
This project proposes the continuation of the existing funded Estuary Management Plan project ’Protecting the Health of the Manning‘, which aims to achieve:
- implementation of a monitoring program in the Manning River which is effective in providing estuary health information consistent with NSW monitoring, evaluating and reporting standards and protocols
- collection, analysis and collation of water quality data for inclusion in a report card for community dissemination, and to enable comparison with other estuaries in New South Wales
- producing and publishing a State of the Manning Annual Report Card to promote the results of the water quality monitoring program and raise community awareness of the health of the estuary and associated human-induced impacts.
This project is planned to partially remove an existing fish barrier (Dyers Crossing Weir) and construct a rock fish ladder to scale the remaining lower half of the weir wall to enable fish access to upstream habitat for breeding purposes. Community consultation has already commenced with adjacent landholders who are concerned about loss of the entire weir wall. The weir pool is an important local platypus habitat, a stock watering pool and serves as a barrier between private properties. Partially removing the wall and constructing a fish ladder to scale the remaining half of the wall is proposed to enable fish passage without the complete loss of the weir pool.
This project includes works to repair riparian areas of the Manning River Estuary, and includes river bank erosion repair works, removal of Sharp Rush, and rehabilitation of saltmarsh areas. This project aims to address immediate threats to the riparian areas through stabilisation of active erosion sites, removal of environmental weeds, and addressing threats to saltmarsh through fencing, grazing removal and weed control for habitat protection and water quality improvements.
The project aims to implement works to rehabilitate saltmarsh, and this will be done through a variety of methods identified for each site; including fencing to exclude stock, weed control, soil erosion treatments, and other methods as appropriate. Removal of Sharp Rush has been identified as a priority action as Sharp Rush is currently spreading in the Manning River Estuary and dominating saltmarsh sites. It spreads by seed on water and stock (legs) to new sites, and smothers saltmarsh vegetation as it is taller and more vigorous than the native Saltmarsh Rush. About 10 hectares is currently known in the estuary. River bank erosion involves implementation of works at active river bank erosion sites to reduce soil loss from sites into the estuary, and works normally involve a number of treatment methods including fencing to exclude stock, rock fillets (in estuary) to enable Mangrove recruitment, earthworks (to reshape banks to reduce steepness and enable access), surface erosion control (hydromulching and seeding) and revegetation (Lomandra and riparian trees/shrubs) to provide long-term stability and deep soil keying-in.
The aim of this project is to protect water quality in the Manning River estuary and includes projects to assist landholders to implement riparian fencing (to exclude stock from river frontages to provide infiltration zones of ungrazed vegetation to allow natural regeneration, improve river bank stability and reduce sediment and nutrients entering the waterway from overland flows). The project plans to implement projects in collaboration with private landholders. The project also includes implementation of roadside erosion works to reduce sediment and nutrients from entering waterways and into the estuary. The project plans to involve the Local Land Services in the development and implementation of projects given their history of work in this area, and their cost benchmarks will be used to assess project proposals. Landholders will be required to involve Greater Taree City Council staff in development of the project to ensure they are technically sound, and contribute to the implementation and ongoing maintenance of the project.
This project aims to protect the water quality of the Manning River estuary, and includes projects to review and upgrade eight gross pollutant traps (GPT), implement additional measures to reduce pollutants from urban waterways, implement dairy nutrient management works within the floodplain, and undertake soil erosion control works to reduce sediment inputs into the estuary. Browns Creek in Taree will be a focus for implementation of the works as Greater Taree City Council (GTCC) is currently developing a pollution control strategy with the Friends of Browns Creek group, which will prioritise sites and identify a range of treatment options (e.g. surface swales, GPTs, table drain treatments etc). If there are sufficient funds then additional sites will be used to implement additional works (such as Racecourse Creek at Old Bar, Wards Creek at Harrington, etc). The Dairy effluent management projects will be developed using the existing programs and networks developed by the Dairy Advancement Group and the Hunter Local Land Services. The results of the proposed programs will be monitored via GTCC's existing Manning River Monitoring Program.
This project includes works to repair riparian areas of the Manning River estuary and includes river bank erosion repair works, removal of sharp rush, and rehabilitation of saltmarsh areas. It aims to address immediate threats to the riparian areas through stabilisation of active erosion sites, removal of environmental weeds, and addressing threats to saltmarsh through fencing, grazing removal and weed control for habitat protection and water quality improvements.
The project aims to implement works to rehabilitate saltmarsh, and this will be done through a variety of methods identified for each site, including fencing to exclude stock, weed control, soil erosion treatments, and other methods as appropriate. Removal of Sharp Rush has been identified as a priority action as Sharp Rush is currently spreading in the Manning River estuary and dominating saltmarsh sites. It spreads by seed through water and stock (legs) to new sites, and smothers saltmarsh vegetation as it is taller and more vigorous than the native saltmarsh rush. About 10 hectares are currently known to be affected in the estuary. River bank erosion involves implementation of works at active river bank erosion sites to reduce soil loss from sites into the estuary, and works normally involve a number of treatment methods including fencing to exclude stock, rock fillets (in estuary) to enable Mangrove recruitment, earthworks (to reshape banks to reduce steepness and enable access), surface erosion control (hydromulching and seeding) and revegetation (Lomandra and riparian trees/shrubs) to provide long-term stability and deep soil keying-in.
Hunter Local Land Services
The project aims to provide detail on priority areas for riparian restoration in the Lower Hunter estuary so that efforts can be concentrated towards achieving on-ground works. The process will begin by providing detail to the concept masterplan. Stage 2 will review available riparian assessments, consult with stakeholders and provide details on current feasibility of sites for works consistent with Strategy 6 of the Hunter Estuary Management Plan 2009. Identification of priority areas will help to make best use of available funding. This process can also be used to form collaborations for identified sites to assist in implementing on-ground works. Riverbank monitoring techniques will be reviewed and the most suitable techniques will be trialled as part of the process of monitoring, evaluation, review and improvement of restoration activities.
This project proposes to stabilise the eroding riverbank along the south arm of the Hunter River between Cobbans Creek and Ramsar Road at Kooragang Wetlands (Ash Island) in the Hunter River estuary through the construction of rock revetment. Rock revetment will prevent further erosion of the riverbank while allowing public access to the river bank. This stage of the work covers the construction at the highest priority section of the site. Planting of riparian vegetation will be undertaken to restore the construction site.
This project fulfils the State Consent conditions for 2 adjacent sites:
- Area E will monitor hydrodynamics, vegetation (including saltmarsh), shorebirds and occurrence of the green and golden bell frog following management of hydrology in Area E to restore saltmarsh as shorebird habitat. The response to vegetation restoration works will be assessed. These results will be made available in a report that can assist in the design and implementation of similar works locally and further afield.
- Baseline monitoring for Dead Mangrove Creek project has been undertaken, now the Consent Conditions for pre-construction will be implemented.
Upper Boggywell Creek Water Quality Improvement Scheme stage 1 design
Upper Boggywell Creek is located in Gannons Park and receives stormwater runoff from the adjacent urban and light industrial areas of Peakhurst. The stormwater runoff contains nutrients and sediments which drains untreated directly into the Georges River Estuary. The quality of this water is poor and lies outside the ANZECC and Georges River regional guidelines. Gannons Park has significance both as a recreational space and also as a habitat for native flora and fauna. The Upper Boggywell Creek Water Quality Improvement Scheme proposes the installation of a bioretention system, storage pond and the daylighting of stormwater lines through the use of swales to increase the quality of the water flowing to Boggywell Creek and the Georges River Estuary. Additionally, the project will lead to the creation of habitat to improve biodiversity and amenity. Concept and detailed designs will be produced as the first stage of this project.
Kempsey Shire Council
Korogoro Creek is a small coastal estuarine environment located adjacent to the coastal village of Hat Head, NSW. Extensively modified by flood mitigation works in the late 1960s, the estuary is approximately 4.5 km long and is currently experiencing varying degrees of riverbank erosion. Management Issue 4 of the adopted Korogoro Creek Estuary Management Plan (2009) identified river bank erosion within the mid to lower sections of the estuary as an issue of concern. This project will include strategically positioning suitably sized, locally sourced rock to construct rock armouring along a number of eroded bank sites (whilst maintaining public accessibility), and construction of mangrove rock fillets when riverbank and river shelf banks allow.
Saltwater Creek and Lagoon is an estuarine ICOLL environment (intermittently closed and open lagoons and lakes) located within the Kempsey Shire local government area. The estuary is adjacent to an expanding urban landscape. A number of stormwater outlets discharge directly into the system. In 2006 the Saltwater Creek & Lagoon Estuary Management Study and Plan was developed. The Estuary Management Program (EMP) identified that the estuary is already at or exceeding its natural capacity to accept catchment loads. Strategy 'U' of the EMP recommends retrofitting stormwater outlets with filtration devices. Funding will assist Council in retrofitting two stormwater outlets with filtration mechanisms.
The development of a standardised means of collecting, analysing and presenting riverine, coastal and estuarine assessments of ecological condition has been identified as a key need for coastal Catchment Management Authorities (now Local Land Services) and local councils who are required to monitor natural resource condition and water quality in these systems. Using the framework of the South East Queensland Ecosystem Health Monitoring Program and protocols developed by the NSW Monitoring, Evaluation and Reporting estuaries team, this monitoring program will provide consistency in monitoring and reporting, and establish the partnerships required for local and regional dissemination of outcomes. It will provide a means of benchmarking the health of the estuary against historic data and will provide a vital mechanism to educate the community about estuary health and the issues influencing it. The project will also provide a means of refining and updating the remedial actions and direction of the established Estuary Management Plans for the estuary and contribute to State of Environment reporting.
Lake Macquarie City Council
Lake Macquarie City Council has been preparing a single Coastal Zone Management Plan for the Lake Macquarie coastal zone. This project will deliver a community consultation program to engage with all stakeholders in the Lake Macquarie coastal zone, and the local community prior to finalisation of the new Coastal Zone Management Plan.
Foreshore erosion around the shores of Lake Macquarie is known to result in a deterioration of water quality, loss of habitat and a reduction in the amenity of these popular areas. This project will rehabilitate eroding foreshores at priority locations using a mix of proven rehabilitation techniques, and the refinement of proven treatments to trial innovative techniques to deal with a projected rise in lake water levels due to climate change. Preliminary works have been undertaken to develop designs to accommodate higher lake levels and using these results a site will be selected to use for demonstrating these techniques. For the other sites the cobble beach treatment, which Council has used successfully in other areas, will be implemented.
The health of the Lake Macquarie estuary is highly dependent on inflows from its catchment and tributaries. The increasing volumes of runoff from urbanised catchments is resulting in an increasing proportion of lake sediment inflows (and other pollutants) being generated by eroding stream banks. This project aims to undertake stream bank stabilisation works and riparian vegetation rehabilitation in priority tributaries throughout the lake catchment. Development of priority sites has been informed by studies and management plans, including the Cockle Creek Improvement Study, the Lake Macquarie Ecological Response Model Project Stage 1 (OEH, 2011) and the Lake Macquarie Estuary Management Plan, as well as ground-truthing of sites by qualified staff. Works will include stream bank and bed stabilisation, rock fillet construction, bush regeneration and riparian revegetation as required. Outcomes from undertaking this project will include: bed and bank erosion control, water quality improvements, improved riparian habitats, as well as increased riparian corridor connectivity.
This is Stage 3 of the Citywide dune enhancement work undertaken by Council in partnership with OEH. This project will increase dune resilience and involve activities including dune reshaping, revegetation, bitou bush eradication, vehicle and pedestrian exclusion strategies (signage, fencing and access restrictions) and dune formation fencing.
The project aims to address the ongoing degradation of wetland areas around Lake Macquarie by undertaking restoration works in priority locations (as identified in the Lake Macquarie Estuary Management Plan and subsequent management plans). These works aim to improve water quality, restore/preserve habitat values, exclude poor management practice and, as a management response, improve the buffering capacity of wetlands against projected sea level rise.
Jacqui Osmond Reserve stormwater outlet protection, Cabramatta Creek
Sedimentation is a major issue for the Georges River estuary where it damages aquatic flora and causes increased turbidity. This project will address a serious erosion issue around a headwall on Cabramatta Creek where there's scouring of the bank and creek. The site is located within Jacqui Osmond Reserve at Warwick Farm and is part of the Cabramatta Creek Catchment which flows into the Georges River estuary. The works will include bank stabilisation using sandstone rocks and some revegetation works to stop the erosion.
Fairy Bower seawall remediation design
The Marine Parade seawall along the Fairy Bower section of Manly Ocean Beach has been identified as being at immediate risk of geotechnical failure, due to undermining by wave action and overtopping during storm events. Wave overtopping constitutes a hazard to pedestrians and buildings behind the seawall crest. This section of Marine Parade is highly utilised by locals and visitors to Shelley Beach, including international tourists. It is also a popular access point for swimming and snorkelling in the adjacent Cabbage Tree Bay Aquatic Reserve.
To identify remedial options and provide detailed cost analysis for seawall remediation, a site-specific study will be required. The proposed project will address public safety risks. It essentially involves design work, for example, conceptual and preliminary design for the seawall remediation, including physical model testing for wave overtopping, assessment of remediation options and scoping design.
Nambucca Shire Council
The Nambucca Heads Surf Lifesaving Club at Main Beach, Nambucca Heads is located in the active hazard area of the beach and is threatened with eventual inundation. The building and the reserve adjoining it are fronted by a stepped concrete seawall which is severely damaged. A consultant&rlsquo;s preliminary report recommends the construction of a static structure to prevent further erosion of the reserve and the inundation of the building. As the building is in relatively good condition, protection of the existing building at this time is more economical than retreat or relocation options.
This project will restore the natural estuarine environment at multiple locations in the Nambucca River around Stuart Island. The estuary health improvements will occur through erosion protection works, including the construction of rock revetments and fillets with artificial reef balls incorporated into the subsurface rock walls, and the revegetation of approximately 400 m of river bank. The project will have benefits for estuarine health by decreasing erosion and creating habitat for estuarine organisms.
Gross Street Reserve Tighes Hill – estuarine creek rehabilitation
The Gross St Reserve, Tighes Hill Estuarine Creek Rehabilitation Project will restore the habitat and ecological performance of approximately 200m of watercourse and 2,500 square metres of associated riparian zone. The creek currently conveys untreated urban stormwater runoff, with significant sediment, nutrient, litter and other pollutants into Throsby Creek and the lower Hunter River Estuary. This project will re-establish natural area values, biodiversity connectivity and local amenity through civil engineering and revegetation.
Rangihou Reserve – Saltmarsh expansion project
This project will undertake saltmarsh protection and expansion in foreshore parkland. Parramatta's Rangihou Reserve is very urbanised and has a very restricted tidal zone resulting in thin strips of remnant saltmarsh species behind existing mangroves. Large areas of turf compete with existing saltmarsh in areas of inundation. The project involves the removal of fill adjacent to the mangrove zone in order to provide a valuable area for fish breeding and other aquatic organisms. The project will also involve a native planting buffer zone to protect the saltmarsh/mangrove zone from encroachment by weeds and nutrient runoff, and to separate critical habitat areas from other parkland activities and impacts, including a new cycleway. The project is 600 metres upstream from two previous saltmarsh expansion projects undertaken by Parramatta City Council in 2007 and 2011.
Mona Vale beach dune restoration – Stage 2
The dunes at Mona Vale beach are continually windblown resulting in dune creep and sand deposits in the adjacent reserve. In order to prevent or minimise future environmental damage, Council will remove all existing fencing to the dune south of the Surf Life Saving Club to the end of Surfview Rd and reshape the dune. Fencing will then be upgraded or replaced as appropriate and the dune revegetated.
Tanilba Bay foreshore erosion management works
This project will implement the second stage of the Tanilba Bay foreshore erosion management plan. Stage 2 of the project will install rocky headlands and pocket beaches along the remainder of Peace Park in Tanilba Bay. This will support the successful outcome of Stage 1 and result in longer term foreshore stability whilst providing intertidal habitat.
A hazard risk assessment of Randwick's ocean beaches and cliff lines
The project will undertake coastal risk hazard assessment in accordance with the requirements of the Coastal Protection Act 1979 for beaches and headlands on the open coastline within the Randwick Local Government Area, including Coogee and Maroubra beaches. These iconic beaches provide regional recreational opportunities for the broader Sydney metropolitan area and are international tourist destinations in their own right. Although still featuring significant elements of natural beach systems, these beaches also demonstrate some degradation from the ongoing and increasing pressures of coastal processes and intensive recreational use. Coastal risk assessment will provide direction and critical information for the development of a Coastal Zone Management Plan for Randwick.
Terry’s Creek and Lane Cove River catchment enhancement project
The Lane Cove River is a highly valued estuary draining a catchment area of 88 square kilometres. The catchment includes Terry's Creek, Ryde. This creek has experienced high degradation and change from urban development resulting in consistently high nutrient pollutant levels that connect to the larger estuary, erosion and water quality issues. This project will complete on-ground works at a total of eight locations within Terry's Creek to improve overall water quality to the estuary. This will be achieved by implementation of two stormwater quality improvement devices, using bush regeneration works to remove invasive weed species, plant new riparian areas for habitat improvement and bank stabilisation and construct four erosion control projects to reduce erosion, stabilise creek banks and improve water quality.
Warilla Beach dune and habitat rehabilitation
Warilla Beach is located about 10 kilometres south of Wollongong, adjacent to the entrance of Lake Illawarra. The beach is about 1.8 kilometres in length and is backed by residential property. Historically, there has been no formal management framework for coastal dunes within the Shellharbour Local Government Area. Through the preparation of the Shellharbour Coastal Zone Management Study and more recently the Draft Shellharbour Dune Management Plan, Council is now guided by a management framework that allows for a systematic, coordinated and outcome-driven approach to dune management.
This project is a continuation of a progressive works program for the Warilla Beach dune system. A staged approach to rehabilitation of the dune system has been implemented to allow for feasible milestones and outcomes to be achieved. Previous works have focused on primary and secondary weeding followed by the planting of predominately herbaceous stabilising plants and scrub or woodland species. This project will incorporate similar works, targeting the eradication of noxious weed species and also include the planting of coastal heath or forest plants (e.g. Melaleuca species, Eucalyptus species and Banksia species) with the aim of increasing longer-term dune stability and habitat value.
Shoalhaven City Council
Acid sulphate soil drainage has been identified as a significant contributor to poor water quality in the Shoalhaven River estuary. The project will implement an acid sulphate soil engagement strategy with land owners across the whole Shoalhaven River floodplain and develop drainage remediation demonstration sites for two priority drainage sub-catchments.
Shoalhaven City Council has gathered a large body of knowledge on coastal management which has been incorporated into a draft Coastal Zone Management Plan. This project will design and deliver a remediation strategy that will require a community engagement strategy to explain the fundamentals of coastal management, discuss the implications of coastal risk, address misconceptions, answer questions and explore adaptive management options for coastal communities.
Orient Point displays typical bank erosion of a shoreline adjoining a trained river entrance due to tidal scour alteration. This project will improve bank stabilisation using multiple groyne structures, sand nourishment, foreshore access management and revegetation.
Stormwater works to improve water quality and corridor along Tarban Creek
This project will improve water quality in Tarban Creek through the installation of a gross pollutant trap in the tributary of the creekline. Coastal saltmarsh (an endangered ecological community) and mangroves downstream are deteriorating rapidly due to the impacts of dissolved and gross pollutants, sediments and high nutrient waters from stormwater run-off, sewage overflows and weed invasion. Riverglade Reserve and Tarban Creek Reserve form part of a regionally significant wildlife corridor linking the Parramatta and Lane Cove rivers. They support small breeding populations of indigenous birds that have disappeared from much of urban Sydney, e.g. small passerine (perching songbirds) birds. Bush regeneration works will restore 5 hectares of core habitat, particularly for small passerine and migratory birds and threatened animals; i.e. the grey-headed flying fox.
The works above have been identified as high priority actions in the Parramatta River Estuary Coastal Zone Management Plan (2013) and Estuary Vegetation Rehabilitation Action Plan (2011) for the reserves.
The Council of the Shire of Hornsby
Estuarine health is influenced by the quantity and quality of runoff. Consistent and frequent water quality data collection will assist catchment managers in the assessment and reporting of estuarine health matters. Currently Hornsby Council manages 5 real-time water quality monitoring buoys in the Lower Hawkesbury, which provide useful information to commercial fishers, oyster farmers, recreational fishers, boaters, researchers and catchment managers. The information collected during the last five years has been integrated into a number of tools that assist community and estuary users with their operations, in particular, the measurement and management of algal blooms. These tools offer community and estuarine users swimming condition maps and access to publicly available real-time water quality conditions.
Funding is sought to continue this program in order to keep monitoring the health of the Hawkesbury. In particular, the ongoing monitoring will assist in the quantification of inter-annual variability and environmental trends. Maintaining long-term data series is vital under current changing climatic conditions. Quantifying environmental changes and identifying exceedances of water quality thresholds associated with current warming of oceans and estuaries will assist with the management of potential emerging aquatic diseases, pests and harmful algae blooms. Data collected from this monitoring program will assist researchers to better understand estuarine processes and will complement and enhance the state-wide monitoring and evaluation reporting initiatives.
Restoration of public foreshore vegetation and tributaries flowing into the Hawkesbury River estuary is a high priority for the Lower Hawkesbury Estuary Management Plan (2009). This project delivers an on-ground works program to restore and rehabilitate riparian buffer vegetation at Brooklyn Park, Salt Pan Reserve and Bar Island. In particular, the extent and quality of endangered ecological communities, including swamp sclerophyll forest on coastal floodplains, swamp oak floodplain forest and coastal saltmarsh will be improved. Furthermore, restoration of riparian vegetation will reduce impacts from stormwater by removing and retaining pollutants (e.g. nutrients) that would, otherwise, enter the estuary. The on-ground restoration work will improve vegetation condition with natural regeneration and supplementary planting in identified areas. Drainage lines will be planted to reduce erosion, sedimentation, nutrient loading and weed dispersal before reaching the Hawkesbury River. Foreshore restoration works will reduce weed encroachment, stabilise embankments, improve water quality and enhance the habitat quality. Six hands-on activities (i.e. native plantings, flora and fauna surveys) will be organised to raise community awareness of the local riparian environment.
Tweed Shire Council
River bank erosion is a serious issue affecting a large proportion of the middle and upper reaches of the Tweed Estuary. In many locations, erosion directly impacts main roads and the proximity between bank erosion and roads (often less than 4 metres) necessitates the use of full bank height structural rock revetment in stabilisation projects. Bank protection structures are acknowledged to have serious ecological and amenity impacts. Where possible, Council is seeking to undertake erosion stabilisation projects that utilise a bio-engineered approach and maximise ecological outcomes. Designs are being developed to protect bank toes from scour while enhancing riparian vegetation. This project presents an opportunity for Council to stabilise a significant reach of eroding bank (400 m) without the need for full structural revetment. Works will include stock fencing, revegetation and if appropriate, the construction of wake wave energy dissipation structures (rock fillets) to create sheltered embayments where phragmities can regenerate.
Kingscliff Beach foreshore has major public assets within the immediate hazard zone. Severe coastal erosion in recent years has highlighted the vulnerability of these public assets. Following extensive community consultation and consideration of issues, council has adopted a protection strategy for a 500-metre length of Kingscliff foreshore. Preliminary studies and some on-ground works have been completed. This project is the preparation of an integrated environmental impact study (EIS) for the adopted public foreshore protection option at Kingscliff, being construction of a seawall and implementation of sand nourishment. This project is Stage 3 of the EIS and approvals process, the previous stages being feasibility and preliminary impact assessments of the sand nourishment placement and sand extraction from the Tweed River. The project will provide an integrated assessment of all elements of the foreshore protection plan.
Technical guidelines for the design of protective works at Collaroy–Narrabeen
The Collaroy–Narrabeen Beach embayment is characterised as having the most highly capitalised shoreline in Warringah. Development along the beach is also classified as the third most at-risk nationally, and most at-risk in NSW, from coastal processes. Collaroy–Narrabeen Beach also has a history of ad-hoc emergency protection works being undertaken during and after coastal storms.
The project will develop guidelines on the design requirements for new and upgraded protective works at Collaroy–Narrabeen Beach. The requirements will include design standards, alignments and required setbacks. Additionally, the guidelines will address council's intention to have all future protective works contained on private property and existing protective works on public land be removed.
This information will provide the council and property owners with clear direction on the suitability and requirements for all proposals to upgrade or build new protective works at selected locations along Collaroy–Narrabeen Beach. Application of the guidelines will ensure that any future protective works are constructed to the prescribed standards ensuring consistency in siting and quality as well as maintenance of the beach environment.
Lake Illawarra estuary health monitoring and reporting
The 2010 NSW State of the Catchments Report for Estuaries and Coastal Lakes indicates that Lake Illawarra is in very good condition, but subject to high pressure. The pressure on the lake is intensifying, as large greenfield areas in its catchment continue to be developed. How the estuary is responding to increasing catchment pressure and whether better control measures are necessary to protect its health requires a targeted monitoring, evaluation and reporting framework that can provide the information to address these issues. This project will review past monitoring activities to formulate and implement a monitoring, evaluation and reporting framework that will assist Wollongong and Shellharbour Councils to respond to the emerging challenges of protecting the health of Lake Illawarra, whilst delivering other community goals in this region.
The project aims to undertake weeding and revegetation at 5 sites (Tallawarra, Fred Finch Park, Windang Peninsula Heritage Park, Wollamai Point Reserve, and Brooks Creek Estuary) around the Lake Illawarra foreshore. This project will improve 5 km of lake foreshore over an area of 9.5 hectares. Weed control will improve the condition of the lakefront endangered ecological communities, including Swamp Oak Floodplain Forest and Saltmarsh, and revegetation will increase estuarine riparian habitat and improve bank stability to improve water quality draining into the lake.
Whartons Creek is a small intermittently closed and open lake or lagoon with a catchment of 210 hectares draining to Bulli Beach. Whartons Creek periodically opens to the north, causing steep scarping of the dunes at Bulli Beach. This dune erosion greatly reduces accessibility and amenity at the beach. This has resulted in council seeking necessary approvals and manually excavating the creek entrance to open it in a direct easterly path to the ocean.
This project aims to investigate local coastal processes which influence the entrance behaviour and cause shoreline erosion, and to recommend strategies for council to more effectively manage the stabilisation of the entrance. The project will result in an entrance management study and policy, and a review of environmental factors for adopted management options to allow improved and efficient ongoing management of the entrance of Whartons Creek.
Councils need to understand the factors influencing the spatial and temporal patterns of change along their coastlines in order to make effective coastal zone management decisions. For Wollongong City Council, beach and dune management issues have become a significant challenge in recent years, and management intervention has sometimes been necessary without a full understanding of their likely long-term impact. This project involves continuing beach and dune monitoring at selected locations where works have been undertaken or are planned, for a better understanding of the coastal processes that shape these landforms and the likely impacts of any intervention works. This information will assist council in ensuring that management actions undertaken bring about effective and enduring solutions.
This project seeks to restore and enhance the dune vegetation behind the patrolled areas of 7 beaches of the Wollongong Local Government Area: Bulli, Woonona, Bellambi, Corrimal, Towradgi, Fairy Meadow and Wollongong City beaches. Key dune vegetation management actions were included in the 'Dune Management Strategy for the patrolled swimming areas of 17 beaches' prepared in 2013. The project includes mapping the existing vegetation in the designated areas, preparing site management plans for each beach, undertaking weed control, removal of dead and senescent vegetation (particularly subspecies of Acacia longifolia), undertaking revegetation works with appropriate native species and setting up a Dune Care Volunteer Program.
Woollahra Municipal Council
In 2013 council completed the first stage of the Woollahra Coastal Zone Management Plan (WCZMP: Stage 1), which provides an understanding of seawall condition along with a geotechnical assessment of the seawalls within the Woollahra foreshore area. In this plan Lyne Park Seawall was reviewed and it was recommended that ‘significant lengths of wall require urgent repair within 2 to 3 years&rlsquo;.
This project covers the preparation of detailed design, investigation, review of environmental factors and all relevant approvals from state government agencies for the staged construction of the north-eastern section of Lyne Park seawall in future financial years.
In 2013, Woollahra Council completed the first stage of the Woollahra Coastal Zone Management Plan (CZMP) which provides an understanding of coastal processes, estuary health, foreshore and seawall condition. Stage 1 summarises the existing and potential future issues, identifies data gaps, and provides a list of potential management options for Council consideration. The investigations carried out in Stage 1 provide Council with comprehensive and scientifically-based information to inform operational changes, monitoring programs, urban planning decisions, community consultation and education activities. The findings of the investigations and the list of potential management options identified in Stage 1 will be used as a starting point to develop a clear action plan for Council. Completion of the CZMP will involve addressing some of the data gaps identified in Stage 1, conducting consultation activities with key internal and external stakeholders, and developing a final CZMP for Woollahra.
Soldiers beach restoration plan – investigation and design
Soldiers Beach coastal foredunes are degraded and unable to perform their natural function as a buffer to coastal storms. This project will prepare a restoration plan that will address actions identified in the Coastal Zone Management Plan. The plan will be utilised to reduce exposure of coastal development to erosion hazards, improve resilience of coastal ecological communities and improve recreational amenity.
