An overview of the key factors, rules and assessment criteria for each management zone is provided in the summary sheets which are available for download below. The summary sheets are included as a guide only.

A transitional provision has been included in the Floodplain Management Plan for the Macquarie Valley Floodplain 2021. This provision mitigates any disadvantage applicants may face as a result of significant delays in the assessment of the flood work applications while ensuring that a comprehensive of assessment criteria is applied to the application. The latter providing for the long-term protection of the floodplain, environmental assets, cultural values and flood flow paths. More information about this transitional provision is available in a fact sheet.

Plan status

The plan commenced on 24 September 2021 and is due for extension or replacement on 30 June 2032.

Community consultation

The department road-tested the major concepts of the plan with key stakeholders during a targeted (informal) consultation process over the period Thursday 11 to Friday 26 May 2017.

The feedback received from targeted consultation was considered by an Interagency Regional Panel prior to the preparation of the plan for public exhibition.

Community input into the preparation of the plan was invited during public exhibition over the period Monday 16 July 2018 to Thursday 13 September 2018. The department notified stakeholders via a media release, the Have Your Say portal, newspaper advertisements and notification letters to key stakeholders and landholders whose properties within Management Zones A and D within the plan area. The department also hosted individual appointments with interested stakeholders to provide greater detail about how the rules and assessment criteria would be applied to flood works in each zone. Appointments were hosted in Quambone, Nyngan, Warren, Narromine and Dubbo in July and August 2018.

A total of 49 submissions were received during the public exhibition period. The main areas of concern identified in the submissions were the method for mapping the draft management zones, the location of the draft management zones and the inclusion of existing works within the draft management zones.

All submissions were considered by an Interagency Regional Panel. A number of changes were made to the draft plan including refinements to the management zones (where supported by the management zone method including hydraulic, ecological and/or existing planning arrangements criteria).
