Estuary Management Planning

What is council doing to look after our estuaries, lagoons and wetlands?

Council has worked with its community to develop a series of catchment-focussed management plans which aim to improve the health of coastal wetlands while enabling their sustainable use.

Lower Hawkesbury Estuary Management Plan 2009

The Lower Hawkesbury Estuary Management Plan provides strategic management for the estuary from Wisemans Ferry to Broken Bay, excluding Pittwater and Brisbane Water.

This plan was adopted by Hornsby Shire Council on 11 March 2009 and by Gosford City Council on 18 March 2009.

The plan contains a list of recommended strategies that have been prioritised according to the goals and objectives identified during workshops which were attended by members of the Berowra and Brooklyn Estuary Management Committees, key stakeholder groups and government agencies.

The plan includes timeframes, costs, responsibilities, measurables and other information related to each of the strategies and will direct council's investment and strategic direction for estuary management for the next 10 years.

The plan also provides a mechanism for future monitoring and evaluation of the success of the plan’s implementation, along with contingencies in the event that specific targets and/or overarching goals and objectives are not met.

The implementation of this plan is overseen by the Lower Hawkesbury Estuary Management Committee.

Brisbane Water Estuary Processes Study (2009)

Before management options for Brisbane Water could be meaningfully considered, it was necessary to define the ‘baseline’ conditions of the various estuarine processes and interactions between them by carrying out an Estuary Processes Study.

The Brisbane Water Estuary Processes Study was adopted by council in 2009.

Brisbane Water Estuary Management Study (2010)

The Estuary Management Study uses the information from the Estuary Processes Study, together with feedback obtained from the community and additional studies, to define management objectives, options and impacts.

The Brisbane Water Estuary Management Study

  • Identifies the significance of Brisbane Water in terms of broader coastal planning issues;
  • Identifies essential features of the estuary, be they physical, chemical, biological, aesthetic, social or economic;
  • Documents current uses and conflicts of use in Brisbane Water;
  • Identifies possible land uses and assesses their impact on the essential features;
  • Assesses the need for nature conservation and remedial measures;
  • Identifies and assesses management objectives; and
  • Assesses planning controls, works and other strategies to achieve these objectives.

Coastal Zone Management Plan for Brisbane Water Estuary 2012

A Coastal Zone Management Plan for Brisbane Water was adopted by council on 3 July 2012. The Plan consists of a scheduled sequence of recommended activities that need to be undertaken to achieve the following overarching aims for the management of the Brisbane Water estuary:

  • Protect, rehabilitate and improve the natural estuarine environment;
  • Manage the estuarine environment in the public interest to ensure its health and vitality;
  • Improve the recreational amenity of estuarine waters and foreshores;
  • Recognise and accommodate natural processes and climate change; and
  • Ensure ecologically sustainable development and use of resources.

The plan adopts the recommendations of the Estuary Management Study and includes a list of 183 actions for implementation.

In recognition of the fact that resources are limited, and that some actions are dependent upon the implementation of other actions, it is recommended that, in the first instance, the implementation focuses upon the top 72 highest priority management actions.
