Bega Valley Shire Council

Bega Valley Shire Dune Protection and Rehabilitation Program - Stage 3

This project seeks to build on a recently completed large-scale program of dune protection and rehabilitation which targeted the shire's urban beaches to rehabilitate and stabilise two sections of beach dunes. It will remove, repair and replace existing dune infrastructure in two areas on the Bega Valley Shire open coast at Short Point Beach (southern end) and Tathra Beach (northern end), as they have been identified as the next highest priority beaches requiring rehabilitation.

The project will be the third phase of the council's dune rehabilitation project. The nature of the works will include removing redundant infrastructure and replacement of infrastructure where required (including fencing, board and chain access ways and signage). Additional actions include weed removal, native species replanting in disturbed sites and installation of interpretive signage.

Byron Shire Council

New Brighton Beach Scraping Works 2013-14

The project entails implementing beach scraping works at New Brighton Beach in Byron Shire. It is envisaged that the works will be part of an ongoing beach scraping program at New Brighton over coming years.

New Brighton Beach was identified in the Byron Shire Coastline Hazard Definition Study (WBM Oceanics 2000) as subject to an immediate or short-term threat of coastal erosion and inundation, with both public infrastructure and private development lying within or just landward of the immediate coastal hazard zone. The aim of the beach scraping works will be to maintain, in the short term, a preferred dune profile, beach volume, beach accessibility and recreational amenity at New Brighton Beach. The works will not remove the immediate coastline hazard threat to infrastructure and private property from a design storm event (100 year ARI), but they are likely to modestly reduce the severity of the threat.

Clarence Valley Council

Shoreline erosion management at Sandon Village

A management plan is required to manage active shoreline erosion which has resulted in the loss of part of a public reserve and threatens private land/dwellings at Sandon Village. The adjacent waterway is within the Solitary Islands Marine Park and management of the coastal hazard must be sensitive to the high value environment and reduce the risk to public and private land, and public safety for users of the sandy beach environment. Ad hoc works have been completed in attempts to reduce erosion. These structures/treatments may cause adverse impact to unprotected sections of the shoreline and increase public risk to beach users as the structures degrade. An assessment of the coastal processes and management options will be made before the council determines a sustainable management response.

Investigation of sand sources in the vicinity of Wooli Beach

Wooli Beach is a designated coastal erosion 'hot spot'. The Wooli community has indicated during public exhibition of the draft Wooli Village/Beach Coastal Zone Management Plan (CZMP) that it supports protection of the village and beach environment rather than planned retreat. The community prefers that the sandy beach amenity is maintained with management solutions to preserve that amenity. Beach nourishment seems to be an essential component of any CZMP that aims to preserve beach amenity and the village assets into the future, whether used in combination with other management (such as terminal rock revetments, beach scraping) or on its own. Potential sand sources in the vicinity are not well documented. Further, they are likely to be located within national and/or marine park estates. In order to determine if local sources of sand are available, an investigative study/report is required. This will better inform draft actions in a revised draft CZMP.

Coffs Harbour City Council

Coastal Planning for Coffs Harbour: Implementation of CZMP

A high priority action in the recently adopted Coastal Zone Management Plan (CZMP) is the formulation of planning controls and updated policy for the coastal zone. The council's Coastal Processes and Hazard Definition Study and CZMP have defined coastal hazards and risk areas for different timeframes and sea level rise (SLR) scenarios. The council’s existing Coastal Policy and planning controls are very simplistic and do not provide adequate guidance for the range of SLR scenarios, planning timeframes and risk areas associated with the coastal zone as detailed in the coastal zone.

New coastal planning controls and policy are required to integrate the CZMP/Hazard studies into the council’s DCP and planning procedures. The project will also integrate coastal hazard planning into the Coffs Harbour LEP. The objectives of this project are to update council coastal planning controls and develop a DCP that is integrated with coastal hazard and coastal risk areas in line with State Coastal Policy and the LEP.

Eurobodalla Shire Council

Determination of Sea Level Rise Planning Benchmarks - Eurobodalla Shire

This project will examine the utility of local tide gauges to measure any trends of significance to the Eurobodalla coastline. This data will be analysed to determine a minimum baseline position to indicate what has occurred historically. An estimate of sea level rise projections will be determined through examination of the most recent literature published by leading Australian and international institutions. The projections will be separated into multiple planning periods to reflect different strategic applications such as short-term commercial development, residential housing, infrastructure planning and long-term land-use planning.

The proposed approach will facilitate more flexibility in the assessment of development through consideration of a wider range of planning periods, development designs and projected risk over the life of the development. An accompanying guide note on the application of the planning benchmarks will be produced to assist planners and the community understand the application of sea level rise planning benchmarks.

Great Lakes Council

Jimmy's Beach - Trial Nourishment from Winda Woppa

This project will trial sand nourishment from Winda Woppa to Jimmy's Beach by physical movement over a two-year period, as recommended in the Jimmy's Beach Sand Nourishment Assessment report 2012. The project is designed to address the overwhelming issue of sand erosion faced along the beach. The stages of the project will gain approvals from authorities, commence trial nourishment regimes from Winda Woppa and conclude with a long-term feasibility report. Beach profile monitoring programs will also supplement the trial nourishment regimes to provide recommendations and evaluate the effectiveness of the beach nourishment management.

Elizabeth Beach Inundation Coast Zone Management Plan

The drainage basin behind Elizabeth Beach is subject to coastal inundation during various design sea conditions. Sea water can enter via a large arch culvert along the small coastal creek located in the eastern corner of Elizabeth Beach, flooding the basin area and affecting inland margins of Boomerang and Blueys beaches. Preliminary investigation has shown that, under 1% AEP (annual exceedence probability) sea conditions, the ocean level will have sufficient time to equilibrate with levels inside the drainage basin. Sea level rise will increase internal flooding by the commensurate amount. The existing arch culvert (council asset) on the creek forms a convenient control point to moderate the amount of sea water allowed into the basin. The project will investigate the use of flood gates to reduce coastal inundation risk while still allowing for appropriate environmental flooding to maintain hydrological regime and water quality.

Greater Taree City Council

Old Bar coastal habitat restoration

The project aims to protect and conserve the dunes at Old Bar Beach, while ensuring that access to the beach can be achieved as per the Emergency Action Plan (EAP) and the draft Coastal Zone Management Plan (CZMP). The project will:

  • educate the community by providing interpretive signage at key locations along Old Bar Beach, outlining the potentially adverse impacts of human activities on the dunal system
  • minimise the potential for erosion to the dunal system
  • remove a beach access point to reduce erosion
  • provide a central pedestrian access to the beach to minimise the potential for erosion.

Hunter Councils

Applying an objectives-based decision support framework to identify management options and pathways

This project will provide specialist mentoring and facilitation to assist Wyong and Gosford Councils apply the decision support framework ('The Handbook') developed for Hunter and Central Coast Councils to objectively identify, assess and determine management options and pathways for vulnerable coastal areas located at North Entrance, Toowoon Bay and Wamberal Beach. The project will enable councils to:

  • establish clear, agreed management objectives for the coastal hazards
  • develop and implement effective communication and engagement strategies for key decision-makers, stakeholders and the wider community
  • filter a range of potential management options (such as development and strategic land-use planning controls, infrastructure protection and maintenance, protection works, planned retreat) for each site
  • identify potential adaptation pathways, along with triggers and thresholds to inform the timing of implementation of management options identified through the filtering process
  • determine the most appropriate economic options assessment method (encompassing social and environmental impacts) for informing the final selection of preferred management options and pathways.

Lake Macquarie City Council

Slip slidin' away - Lake Macquarie headland cliff stability and safety project

The Headland Cliff Stability and Safety project will improve safety and access for the public on coastal headlands and rock platforms on the Lake Macquarie coast. A detailed geotechnical assessment of cliff hazards will be conducted at several at-risk headland locations identified in the Lake Macquarie Coastline Hazard Study, including Dudley, Redhead, Swansea Heads, Caves Beach and Catherine Hill Bay. Based on the findings of the geotechnical investigation, risk assessments for priority sites will consider the consequences of the hazard on structures, such as roads and dwellings, and activities, such as walking, sight-seeing, rock fishing and surfing. Risk-mitigation works will be carried out in locations identified in the risk assessment. The works may include installing signs, managing access with fencing and defined pathways, and minor stabilisation and revegetation works.

Nambucca Shire Council

Nambucca Beaches Access Ways Program Stage 2

Many of the shire's existing pedestrian beach access points have been eroded through high water levels and storm events, and are unusable and unsafe for many beach users who are disabled or frail. A project is currently underway to create all-conditions access to at least six of the highest priority accessways, and funding sought under this grant program will enable us to continue the implementation of the works we have identified as needing treatment in stage 1. This project will enable the council to continue implementation of actions in the Nambucca Coastal Zone Management Plan in constructing at least five high quality, all-season access points to beaches that provide greater public safety and protect sensitive coastal landforms.

Newcastle City Council

Coastal Educational Signage

Newcastle's coastline is an exceptional natural asset for residents and visitors. The foreshore and rock platforms of the coastline are home to a great diversity of flora and fauna, including a number of threatened shorebird species. The council has completed studies on the intertidal and avian values of the Newcastle coastline and investigated the levels of human use of the coastal rock platforms. All of these studies have recommended the council implement a community education program to highlight and protect the biodiversity values of the coastline.

The proposed project will include the design, development and installation of educational signage along the Newcastle coastline. The aim of the project is to educate the community about the biodiversity values of the coastline and outline how the community can minimise its impact on the flora and fauna of the coastline.

Coastal Cliff Stabilisation Works at Shortland Esplanade - Construction Stage

This project involves the implementation of coastal stabilisation works at Shortland Esplanade, Newcastle East. Sandstone rock cuts have been identified at this location in the draft Newcastle Coastal Zone Hazard Study, with rockfalls onto Shortland Esplanade recorded at this site, both historically and currently. The draft study recommends that loose and detached blocks are removed from the rock face. In addition, the study identifies weed vegetation growing in the rock defects is to be poisoned to allow for assessment of the condition of the existing concrete revetments and retaining walls. Native vegetation reflecting the local coastal species palette is to be used in revegetation/stabilisation works.

Pittwater Council

North Avalon Beach Dune Restoration

The frontal dune at North Avalon Beach has blown out and moved off the beach and up into the adjacent reserve. The problem has been exacerbated by removal of dune fencing by local surfers and loss of vegetation as well as the major access track onto the beach, funnelling sand up onto the reserve. The council proposes to push the sand now on the reserve back onto the dune, reorientate the access track, construct dune fencing to all edges and revegetate the affected area through plant propagation and dense planting of the indigenous Coastal Foredune Wattle Scrub Association vegetation. The council, at its own cost, will look at rebuilding the car park edge to better accommodate local surfers being able to view the surf. The project has been developed through a Plan of Management process for the whole of Avalon Beach.

Mona Vale Beach Dune Restoration

The dunes at Mona Vale Beach are continually windblown, resulting in sand deposits in the adjacent reserve. The council proposes to remove all existing fencing to the dune north of the Surf Life Saving Club and reshape the dune. Fencing will then be upgraded or replaced as appropriate and the dune revegetated, through a plant propagation and dense planting of the indigenous coastal foredune species. Additionally, a timber board accessway will be installed to encourage appropriate pedestrian access. The council, at its own cost, will returf the adjacent reserve area and upgrade picnic facilities to improve recreational amenity.

Port Macquarie-Hastings Council

Lake Cathie Coastal Sedimentary Processes Conceptual Model

The township of Lake Cathie and its associated beach are located approximately 18 km by road to the south of Port Macquarie on the Mid-North Coast. This project will develop a coastal sedimentary processes conceptual model for the coastal region adjacent to the lake entrance, extending north and south with a particular focus on the beach area adjacent to Illaroo Road and Chepana Street.

Lake Cathie Coffee Rock Photogrammetric Analysis

Coastal assets along a stretch of beach fronting Illaroo Road and Chepana Street at Lake Cathie are at risk of immediate and longer term coastal recession. The project will involve undertaking a photogrammetric analysis of the available records in order to quantify the historical long-term recession rates of indurated sands (coffee rock) at the location. Analysis of historical records will enable predictions of future recession rates to be made more accurately.

Port Stephens Council

Sandy Point to Conroy Park Process Study, Drainage Adaption and Seawall Redesign

This project will undertake a coastal processes study of the Sandy Point to Conroy Park foreshore to develop a plan for holistic sustainable erosion management and protection of the foreshore, its homes, Conroy Park Beach and the immediate aquatic environment.

Currently the area is experiencing significant erosion problems: existing structures are ill-designed and in many cases illegal and significant erosion of the unprotected beach stretch has resulted in a steep beach scrap. At present the seawall at the eastern part of Sandy Point is sinking, three groins are stopping sand migrating along the foreshore, causing beach erosion to the west and the three drainage outfalls are adversely affecting the littoral movement of sand in the area. The drainage outfalls are also having a negative effect on the surrounding seagrass beds.

Rockdale City Council

Sandringham Bay - Bank stabilisation

Over the past 12 months due to a combination of beach sediment transport and storm action in Botany Bay, severe shoreline erosion has occurred along Sandringham Bay south of Vanston Parade/Lena Street, Sans Souci. This beach erosion has caused the partial collapse of the existing sandstone boulder embankment, undermining of the adjacent public pathway, exposed the roots of two large pine trees and undermined the concrete seawall of Sandringham Baths.

To address this erosion and stabilise the bank and seawall, it is proposed to supply and place a series of geotextile sand pillows along Sandringham Bay, south of Lena Street over a distance of 130 m. In addition to these sand pillows, a 20-m length of sandstone boulder revetment will be restored near the existing pine trees. Sand pillows will also be supplied and placed along a 31-m section of the stepped seawall to address the undermining of the concrete seawall at Sandringham Baths.

Shellharbour City Council

Warilla Beach Dune and Habitat Rehabilitation

Warilla Beach is located approximately 10 km south of Wollongong, adjacent to the entrance of Lake Illawarra. The beach is approximately 1.8 km in length and backed by residential property. The proposed project involves continued rehabilitation of dune vegetation to re-instate the dune ecosystem. Previous works have focused on primary and secondary weeding followed by the planting of predominantly 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 (such as Melaleuca, Eucalyptus and Banksia species) with the aim of increasing longer term dune stability and habitat value. The project will also focus on rehabilitating areas within the dune system that have experienced recent dieback of Acacia species. Rehabilitation of these areas will reduce further impacts on the dune system, including loss of sand, native vegetation and habitat, uncontrolled access and the spread of noxious weed species.

Entrance Channel Dredging and Warilla Beach Renourishment

Warilla Beach is located approximately 10 km south of Wollongong, adjacent to the entrance of Lake Illawarra. The beach is approximately 1.8 km in length and is backed by residential property. The Lake Illawarra Entrance Channel is a dynamic channel system of marine sands which accumulates within sections of the channel. The Shellharbour Draft Coastal Zone Management Plan has identified the central/southern end of the beach as requiring nourishment of the beach area in front of the seawall for public access, amenity and hazard mitigation. Currently there are sections of seawall that are exposed where there was not enough sand from previous nourishment works to fully cover the exposed seawall. Further opportunistic renourishment of Warilla Beach will increase the sand buffer to storm processes, which helps extend the life of the seawall by keeping it largely buried. Known problem areas of shoaling in the Lake Illawarra Entrance Channel will be targeted for dredging to also improve navigation and minimise channel movement. Sand dredged from these areas will be used for the renourishment of Warilla Beach.

Shoalhaven City Council

Coastal erosion: road stormwater impact assessment

Undertake a city-wide road stormwater erosion impact assessment and development of a risk/priority remediation plan for future funding consideration. Preliminary investigations and priority sites were identified in the 2008 SMEC Slope Instability Study.

Sutherland Shire Council

North Cronulla to Wanda Beach: upgrade of beach accessways 26, 17 and 9 and dune maintenance

This project will upgrade beach accessways at North Cronulla Beach (Accessway 26), on the beach side of Elouera Surf Club (17) and the beach side of Wanda Surf Club (9). All three provide access to and from the beach for Surf Club and Council lifeguard vehicles and vessels. The accessways will be upgraded, using recycled plastic decking (which has a grooved surface and provides excellent slip resistance).

Ongoing dune maintenance work will also be undertaken from North Cronulla Beach to Wanda Beach, including dune profiling, weed control, revegetation and fence repairs.

Warringah Council

Warringah Dune Restoration Project

North Curl Curl dunes are largely covered with lantana and acetosa and have limited native vegetation cover. This project involves the removal of target weeds from select dune bays, planting out the area with native coastal species and carrying out ongoing maintenance. Fences delineating the dune bays require repair or installation in order to keep pedestrians out of the sensitive dune vegetation. There is a large amount of bitou bush (a Weed of National Significance) at Dee Why dunes that requires strategic removal. Removing bitou bush at Dee Why would tie in with the Bitou Threat Abatement Plan currently underway at nearby Long Reef headland and help prevent further spread of bitou into adjoining lagoon vegetation.

Wyong Shire Council

Review and update of the Coastal Zone Management Plan for the Wyong Coastline

This project aims to fund a review and update of the adopted Coastal Zone Management Plan for the Wyong Coastline (CZMP) to further identify potential future coastal hazards reflecting local conditions, and prepare for a smooth transition to the new arrangements being developed by the State Government for future coastal hazard management.
