Register for project updates

We are extremely fortunate on the Northern Beaches to have a natural environment that features rare flora and fauna, coastal beaches, headlands, harbours, lagoons, waterways and extensive bushland.

Our incredible coastline is increasingly under pressure from climate change, development and population growth. It’s important we effectively plan and adapt, actively managing our coastal areas now and into the future.

One way we achieve this is through the development of Coastal Management Programs (CMPs) which identify coastal management issues and provide actions, timeframes, costs and funding mechanisms required to address them.

We've prepared a Scoping Study as the first stage of the program - we invite you to review the report and share your feedback.

Overview

  • What is a CMP?

    A CMP is a plan of action for Council, public authorities, and land managers responsible for management of the coastal zone to:

    • address coastal hazard risks
    • preserve habitats and cultural uses and values
    • encourage sustainable development in the coastal zone
    • maintain or improve recreational amenity and resilience, and
    • adapt to emerging issues such as population growth and climate change.
  • Stages of a CMP

    There are 5 stages in preparing and implementing a CMP, and it can take up to 5 years to have a certified program that has been thoroughly researched, developed and consulted on.

    Learn about the 5 stages

Frequently asked questions

What is the purpose of a CMP?

The purpose of a CMP is to create a long-term strategic and integrated plan for the 2,137 km of NSW coastline. CMPs are used by local councils around NSW to establish coastal management goals and actions. Developed in consultation with the community and state government, a CMP creates a shared vision for management and provides the steps of how to get there through local input and costed actions.

We already have Coastal Zone Management Plans (CZMPs) and Estuary Management Plans that cover our coastline. What’s the difference between these and a CMP?

The development of the CZMPs within NSW occurred under the former Act (Coastal Protection Act 1979). Council has two certified CZMPs under the former Act - ‘Bilgola and Basin Beach’ and ‘Collaroy-Narrabeen-Fisherman's Beach’. The transition from the CZMP to CMP occurred in 2016 with the introduction of the Coastal Management Act 2016. The Council’s existing CZMP’s have now expired and will be updated in the ‘Open Coast and Lagoons’ and ‘Collaroy-Narrabeen’ CMPs.

CMPs will also incorporate Estuary Management Plans that are currently in place for our four lagoons.

Why are there multiple CMPs? 

The Northern Beaches Council area will be covered by 4 CMPs:

  • Open Coast and Lagoons
  • Collaroy-Narrabeen Beach
  • Hawkesbury-Nepean (incorporating Pittwater waterway)
  • Outer Sydney Harbour (incorporating North and Middle Harbour).

Each CMP targets a specific area which has its own unique communities, coastlines, stakeholders and challenges.

Northern Beaches Council is leading the development for the Open Coast and Lagoons and Collaroy-Narrabeen, while other councils are leading the remaining CMPs which only include part of the Northern Beaches area.

The Open Coast and Lagoons CMP includes all the beaches and lagoons between Palm Beach and Manly except for Collaroy- Narrabeen Beach.

Collaroy-Narrabeen Beach has experienced more extensive erosion and storm events than any other area in the Northern Beaches and has very specific challenges, which is why we are creating a stand-alone CMP for this area.

After successfully completing Stage 1 for the Open Coast and Lagoons CMP, future stages are proposed to progress separately for the open coast and lagoons to give focused attention to coastal and catchment issues. More information relating to the development of the 2 CMPs will be available in the coming weeks.

How long will it take to complete a CMP?

The NSW Government CMP manual prescribes a mandatory five-stage process to developing a CMP. Typically, each stage takes a year to complete, however the time it takes varies upon the baseline information, level of complexity, size and area, and community engagement that has previously been undertaken.

The Open Coast and Lagoons CMP covers a large area (Palm Beach to Manly) and has a wide range of issues. As with all CMPs, it will require technical studies and community and stakeholder engagement, and is likely to take around 5 years to complete.

For the Collaroy-Narrabeen CMP, extensive technical studies and community engagement will occur with Council aiming to have a certified CMP in place by 2026.

The Hawkesbury-Nepean CMP (incorporating Pittwater waterway) and Outer Sydney Harbour CMP (incorporating North and Middle Harbor) are at Stages 4 and Stages 2-4 respectively.


How is this funded? 

Council funds the development of CMPs with assistance from the $83.6m NSW Government Coastal and Estuary Grants Program. Council is eligible to apply for funding for both the preparation of reports and implementation of actions identified in the Program.

Who can be involved in the CMP’s development?

There will be a wide range of people involved in the development of all the CMPs. These include technical consultants, subject matter experts, public authorities, other councils, general community, and First Nations people.

Importantly, anyone who would like to be involved in the development of a particular CMP will be given many opportunities to comment, provide feedback and guide each stage in alignment with the values that matter most to them. Click +Follow at the top of the page to sign up for regular updates on the project.

Under what framework do CMPs sit?

Local councils and public authorities are required to manage their coastal areas and activities in accordance with relevant state legislation, policies and plans.

The framework for managing the NSW coast includes:

  • Coastal Management Act 2016 (CM Act)
  • State Environmental Planning Policy (Resilience & Hazards) 2018 (R&H SEPP)
  • Coastal management programs (CMPs), prepared in accordance with the NSW coastal management manual.

Stage 1: Scoping Study

We're currently in Stage 1: Identify the scope of a CMP, often called a Scoping Study.

The study area covers about 38 km of coastline from North Head in Manly to Barrenjoey Headland in Palm Beach. It includes 20 beaches and 4 coastal lagoons (Manly, Curl Curl, Dee Why, and Narrabeen). Beaches are embayed by prominent headlands and rocky reefs, stunning scenery and exceptional habitat.

These beaches are often exposed to energetic ocean swells, which can create ideal conditions for recreation, but also pose risks to coastal structures and coastal activities.
