Pilot Project with Department of Planning and Environment (DPE)

Earlier in March, Council met with the Department of Planning and Environment (DPE) to discuss a Pilot Project to further investigate the methodology and mapping used in our Conservation Zones Review and to explore potential changes to address community and stakeholder feedback.

This is important because the Department will have the final say about any proposed zoning changes resulting from the Review.

Site visit requests and mapping Investigations

We have also undertaken a review of all the submissions to the public exhibition. This has shown:

• Over three hundred submissions raised concerns with the accuracy of mapping, including approximately fifty which requested a site visit.
• Approximately forty submissions requested a site visit based on their concerns about the methodology.

We are conducting a desktop/ online assessment of those submissions which raised issues with mapping accuracy. This work will continue over the next few months concurrently with the Department of Planning and Environment Pilot Program.

Once we reach agreement with the Department of Planning and Environment on a revised methodology, site inspections will be arranged for landowners whose submissions on mapping have not been resolved.

Due to the timing of the Pilot Project with the Department, site visits may not now commence until July/August. We will contact those who requested a site visit to notify them of the delay.

Whilst Council is considering changes to its methodology to address submissions received, it does not propose to conduct site visits where a submission requests one based on methodology, as specific site conditions will not impact methodology.

We are aiming to complete all relevant work by early September.

The outcomes from the Review will help us develop a draft Northern Beaches Local Environmental Plan and Development Control Plan, which will be presented to Council and exhibited for community feedback in 2024.

We will continue to keep you updated.

We anticipate many of the issues raised can be resolved by potential changes to the draft methodology which Council is currently investigating.

Where areas of dispute remain about the accuracy of Council mapping of criteria used in the review, we will engage relevant consultants and contact those landowners who have requested a site inspection.

We are expecting to commence site visits from May 2023.

We are also meeting with the Department of Planning and Environment to discuss the Review, the submissions received, and possible changes. This is important because the Department will have the final say about any proposed zoning changes resulting from the Review.

The outcomes from the Review will help us develop a draft Northern Beaches Local Environmental Plan and Development Control Plan, which will be presented to Council and exhibited for community feedback in 2024.

We will continue to keep you updated.

The Draft Watercourse, Wetlands and Riparian Lands Study (the Study) summarises a series of technical studies undertaken by environmental consulting firm BMT Commercial Australia Pty Ltd, which reviewed existing planning controls across the three former Councils (Manly, Warringah, Pittwater) associated with watercourse, wetland and riparian matters, and provided recommendations and updated mapping to be incorporated into a single Northern Beaches Council Local Environment Plan (LEP) and Development Control Plan (DCP).

The Study comprises Council’s objectives, key terms and definitions, and a draft set of watercourse and wetland maps, including proposed buffers to riparian corridors and wetlands, that apply a consistent mapping methodology across the local government area (LGA).

Northern Beaches LGA has seven major catchments which drain to our coastal lagoons, directly on to the beaches, or into North Harbour, Middle Harbour and Pittwater. Approximately 637 kilometres of watercourses and 240 hectares of wetlands are in the LGA.

Watercourses, wetlands and the riparian land surrounding them are important ecological systems that support aquatic and terrestrial habitat and wildlife, provide connectivity and biodiversity, reduce impacts from stormwater runoff and pollution, and contribute to the character, aesthetics and recreational value of the local area. It is important to protect these areas not only for their own intrinsic significance, but also for the benefits they provide in terms of downstream waterbodies and in modulating flood response.

Northern Beaches Council aims to protect, enhance and restore watercourses, wetlands and riparian land while ensuring protection of public and private property across the Northern Beaches. Council must consider the environmental impacts and risks associated with development adjacent to watercourses and wetlands before giving development consent. The three former Councils mapped and assessed watercourses and wetlands differently, so this Study is necessary to provide a fair and consistent mapping methodology across the LGA.

The outcomes of the Study include:

• Consistent terms and definitions regarding watercourse, wetlands and riparian land.
• Objectives to protect or improve the environmental values and functioning of watercourses, wetlands, and riparian land
• Delineation of riparian corridor widths based on stream order and State Government guidelines, and the development of watercourse categories based on vegetation mapping - Category 1 (Native Vegetation) and Category 2 (Disturbed and Cleared).
• Proposed additional 30 metre buffer for riparian corridors on each side of the watercourse. A 100 metre buffer is proposed from the edge of wetlands.
• New proposed watercourse and wetland maps including proposed riparian and wetland buffers for inclusion in the Northern Beaches LEP/DCP (

The Study and associated maps provide a consistent and evidence-based approach to mapping watercourse and wetland values and buffers across the LGA.

Is the proposed approach to mapping watercourse, riparian corridors, wetlands and associated buffers in the Study a fair way of ensuring that impacts of development on watercourses, riparian corridors and wetlands are adequately considered?
