South Collaroy Foreshore & Stormwater Improvements

Project update: May 2025

Construction of the South Collaroy Foreshore & Stormwater Improvements project has been delayed.

Our team is actively engaged in developing a revised construction staging strategy to ensure the best outcomes.

We will keep you updated as we approach the commencement of construction.

Thank you for your understanding and patience.

Overview of the proposed works

The damaged section of the existing seawall, along with a stormwater outlet at the Rock Pool will be upgraded with new infrastructure designed to contemporary engineering standards, restoring the structural integrity of the seawall, promenade and stormwater culvert.

The work will be conducted using a staged approach to improve the efficiency and increase the capacity of the stormwater network. Additionally, it will enhance pedestrian safety, beach access and visual amenity.

The details of proposed works include:

reconstructing around 70 metres of damaged seawall
reconstructing around 112 metres of the existing stormwater culvert from the Collaroy Surf Club Carpark to the Rock Pool outlet
reconstructing the existing beach access staircase, and
construction of a new junction pit with wet weather surcharge slot.

What you shared during consultation

We sought community feedback on the detailed design plans for the foreshore improvements. Stage 1 consultation on this project occurred in 2021 with key targeted stakeholders informing the concept plans. Stage 2 consultation on the detailed plans took place from 18 July to 18 August 2024.

13 responses were received with majority giving supportive feedback on the design, with some minor suggestions for consideration during construction.

Overview of the Environmental Assessment

In accordance with Part 5 of the Environmental Planning and Assessment Act 1979 (EP&A Act), a REF was prepared by independent consultants for the proposed works.

The REF examines any potential environmental, social, economic, and cumulative impacts of the works and the ways we will mitigate these impacts, including during construction. The REF is an important document to ensure we are considering and protecting our valued beach and surrounding environment.

The REF considers the potential impacts of the proposed works including influence on any physical and chemical, biological, community, natural resource, cultural heritage and matters of national environmental significance.

Key findings of the REF include:

there will be negligible effects to coastal processes both in the near shore and offshore
no environmental harm to fauna and flora species will occur in the vicinity of the works, howver, Council will be applying for a NSW Fisheries permit to undertake the works in order to follow due process.
no Aboriginal or European heritage is expected to be unearthed or impacted during construction
cumulative impacts are considered to be negligible, and,
there is potential for short term environmental impacts during construction and actions are identified to mitigate this risk.

The REF concludes that the proposed works would not result in significant environmental impacts using the proposed mitigation measures.

To minimise any potential impacts from the proposed coastal protection works, a number of mitigation and management safeguards are incorporated into the REF.

The REF lists required actions to mitigate environmental impacts during construction. These actions will be included in a site-specific Construction Environmental Management Plan (CEMP) prepared by the construction Contractor. The Contractor will implement the CEMP during construction to mitigate the risk of environmental impacts.
