Council currently undertakes a range of activities at the Maroochy River entrance and Maroochydore Beach in order to maintain the social, economic and environmental values associated with the area.
A number of Maroochy River mouth coastal structures, for example geobag groynes and revetment walls, have now reached the end of their useful life.
Investigation into future coastal infrastructure upgrades is now taking place as part of the broader Maroochy River mouth management and in line with council’s endorsed Shoreline Erosion Management Plan (SEMP) 2014.
Council is seeking further feedback from the community for the preferred option for the renewal of the Maroochy River groyne field.
Option 1(a) replace existing groynes - geobag to geobag
Option 1(b) replace existing groynes - geobag to rock
Option 2 new 200m rock groyne at Cotton Tree
Option 3 northern channel with constructed beach
Option 4 northern channel with breakwater
Sunshine Coast Council has accepted a recommendation of the independent Maroochy River Estuary Consultation Group (MRECG) to extend the timeframe to consider groyne renewal options at the Maroochy River to March 2018. Community engagement is ongoing via the MRECG.
The first phase of community engagement was to establish the Maroochy River Estuary Consultation Group (MRECG) - this was completed in August 2017.
In addition to the MRECG, local residents have been invited to share their views by attending local community information sessions, completing a survey or providing a submission to the MRECG.
Phase 1 - Maroochy River Estuary Consultation Group
The MRECG charter provides information on the role of the group.
The extent of area covered by the MRECG is represented by the Maroochy River Estuary map.
Professor John Martin, an Emeritus Professor at La Trobe University, has been appointed as the independent chair for the MRECG.
A full list of MRECG members is now available.
Council invited all residents of the region and community interest groups, through an Expression of Interest (EOI) process, to take part in the establishment of the MRECG. A number of the positions on the MRECG are fixed and numbers limited to ensure a fair regional representation.
Expression of interest applications closed on 22 May, 2017.
Phase 2 - Consultation sessions and survey
Online Survey - submissions closed Friday 6 October 2017
Community Information Sessions - closed 29 August 2017
During August five community consultation sessions were hosted by council across the region with 350 people registering their attendance.
Frequently asked questions have been developed in response to feedback from the community consultation process and will continue to be updated throughout the consultation period.
Where to from here
The community information sessions and feedback from the MRECG will provide the community with an opportunity to understand the details of each option available to council, including a breakdown of the social, economic and environmental factors.
Members of the community have made representations and submission to the Maroochy River Estuary Consultation Group for consideration. Submissions closed on 31 October 2017.
All feedback received from the MRECG, information sessions and online survey will be used to assist council to make an informed decision on the selection of a suitable option for upgrades of the Maroochy River mouth coastal structures.
The results of the cost benefit analysis report are now available.
For more information about the project is available in the summary factsheet.
The Maroochy River entrance position naturally migrates in response to the prevailing coastal and estuarine processes with the entrance being located both north and south of Pincushion Island since the 1940’s.
Southern migration of the entrance in the 1990’s saw erosive pressure placed against the Cotton Tree Holiday Park. In 2003 council constructed of a number of groynes and section of seawalls to protect park assets.
A number of these coastal structures have now reached the end of their useful life.
In line with council’s endorsed Shoreline Erosion Management Plan (SEMP) 2014, investigation into future coastal infrastructure upgrades is now taking place.
The SEMP provides a ten year action plan that describes key coastal processes along the Sunshine Coast. The SEMP recommends preferred management options that are underpinned by sound science, coastal engineering principles, community values and the relationship of coastal dynamics.
In January 2017, a report was presented to council at the Ordinary Meeting that sought direction for the future coastal infrastructure upgrades as part of the broader Maroochy River mouth management.
The report included an assessment by WBM consultancy of a range of options in relation to the renewal of the river mouth groyne field.
Council resolved to:
- undertake a further analysis of the economic, tourism, social and environmental impacts of the available options -including the retention of geofabric bags at the Maroochy River entrance groyne
- undertake wide community engagement on the available options to inform any future recommendations.
Post this January meeting, council staff commissioned a condition report of the groyne field utilising the services of coastal consultants International Coastal Management (ICM). The purpose of this report was to identify any immediate risks of the structure whilst consultation was conducted to inform the renewal process.
This assessment was limited to an aerial and visual based inspection where less than 1% of the footings were inspected (note all of these footing investigations showed bags with visible damage or that they had been dislodged). The ICM report identifies significant issues with the structure and recommends an options assessment process including investigating alternate materials. A full response to this report is provided in the Frequently Asked Questions (FAQ's) factsheet.
