Draft Wamberal Beach Terminal Protection Structure Engineering Design Requirements
The Wamberal Beach Terminal Protection Structure Engineering Design Requirements, which outlines minimum engineering specifications and details for coastal erosion protection works in the Wamberal embayment, has been finalised and adopted at the 11 October 2022 Council Meeting following a review of 247 formal submissions received during recent community consultation on the draft document.

Overview
Council engaged Manly Hydraulics Laboratory to draft the Wamberal Beach Terminal Protection Structure Engineering Design Requirements which outline specific criteria for assessment of Wamberal Beach coastal protection development applications.
These Design Requirements outline engineering specifications and details such as the alignment, length of construction, material selection, landscaping, and maintenance requirements. These requirements reflect what the community said was of value and importance during the community consultation period.
This milestone follows on from the completion of extensive community consultation, and expert technical studies to identify an effective and viable long-term solution to beach erosion at Wamberal Beach.
Once adopted these requirements will be used in conjunction with the Environmental Planning and Assessment Act 1979, Coastal Management Act 2016 and Resilience and Hazards SEPP 2018 during development application assessments.
Have your say
Council is performing its regulatory function as a Local Government to develop planning controls which will enable Wamberal foreshore property owners to undertake approved development to protect their assets whilst the beach public amenity and environment is protected appropriately.
The community is invited to:
- Read the Draft Wamberal Beach Terminal Protection Structure Engineering Design Requirements
- View the frequently asked questions (available below)
- Register to attend a virtual drop-n information session to discuss the Design Requirements with project staff
Submissions were to be addressed to the Chief Executive Officer, Mr David Farmer between 29 June and 27 July 2022 via:
- The online submission form (now closed)
- Email: ask@centralcoast.nsw.gov.au
- Post: PO Box 20, Wyong NSW 2259
The Draft Design Requirements note that any development application for a section of seawall at Wamberal Beach will be subject to public exhibition, providing the public with additional opportunities to comment on the detailed design drawings, environmental impact assessments, construction programs and maintenance plans.
When providing feedback to Council your attention is drawn to the provisions of the Government Information (Public Access) Act 2009 which allows for possible access to certain public and personal documentation. View our privacy statement.

Who's listening
Why did Council develop Design Requirements for terminal protection structures (seawalls) and Sand Nourishment at Wamberal Beach?
Council has drafted Design Requirements which outline specific criteria for the assessment of Wamberal Beach coastal protection development applications.
Once adopted these guidelines will be used in conjunction with the Coastal Management Act 2016 and Resilience and Hazards SEPP 2018 during development application assessments.
These Design Requirements outline engineering specifications and details such as the minimum footprint, length of construction, material selection, landscaping, and maintenance requirements. These guidelines reflect what the community said was of value and importance during the community consultation period.
What are the key design requirements identified in the draft Wamberal Beach Terminal Protection Structure Engineering Design Requirements?
- Guidelines for preferred concept design – alignment of seawall – concept design and alignment drawings, site specific geotechnical requirements and shadow modelling design criteria, including guidelines for design life including future modifications
- List relevant legislation
- Guidelines for contamination assessment and remediation and reuse of removed material
- Guidelines for terminal end controls during and post construction, beach access points and beach safety during construction and other environmental aspects.
- Guidelines for construction impacts
- Guidelines for construction schedule
- Guidelines for landscaping and aesthetics
- Guidelines for certification
- Guidelines for seawall maintenance and ongoing responsibility and security
Will the community be able to have a say when development applications for terminal protection at Wamberal Beach are submitted?
Yes. The Draft Design Requirements note that any development application for a section of seawall at Wamberal Beach will be subject to public exhibition, providing the public with additional opportunities to comment on the detailed design drawings, environmental impact assessments, construction programs and maintenance plans.
Will the Wamberal Seawall Advisory Taskforce still operate?
Yes. The Taskforce Terms of Reference were recently revised to provide a focus on sand nourishment. Council will continue to work closely with the NSW Government, through the Wamberal Seawall Advisory Taskforce, to implement a sustainable long-term solution to the coastal erosion issues on Wamberal Beach.
What information was used to inform the development of the draft Design Requirements?
Council has been working with Manly Hydraulics Laboratory (MHL), property owners, the Wamberal Seawall Advisory Taskforce and the broader Central Coast community to understand how to achieve a long-term solution to coastal erosion at Wamberal Beach.
The draft Design Requirements reflect the findings of the MHL Wamberal Terminal Protection and Sand Nourishment technical studies. The $498,996 project was 50:50 funded by NSW Government through the NSW Coastal and Estuaries Grants Program.
The draft Design Requirements support a solution, based on the feedback received from the community and expert engineering advise, to maximise both the amenity of the public beach and the net present value (NPV) for a coastal protection seawall at Wamberal Beach.
How can I find out more information on the draft Design Requirements?
For more information on the draft Design Requirements, you can:
- View the information available on this page
- Contact the Project Manager:

How can I have my say on the draft Design Requirements?
Council encouraged the community to provide feedback on the draft Design Requirements.
Between 29 June and 27 July 2022 the community were invited to:
- Register for a virtual information session with the project team (hosted via Microsoft Teams)
- Provide feedback via the online feedback form (now closed)
What are the next steps for the draft Design Requirements?
Following this public exhibition period, the final Design Requirements will be presented to Council for adoption and then used in conjunction with the Environmental Planning and Assessment Act 1979, Coastal Management Act 2016 and Resilience and Hazards SEPP 2021 during development application assessments.
