Ariah Park and Springdale Floodplain Risk Management Study and Plan

The Ariah Park and Springdale Floodplain Risk Management Study and Plan is at the stage of final draft for public exhibition.

Objectives

The overall objectives of the Ariah Park and Springdale Floodplain Risk Management Study were to:

• Assess the impacts of flooding on existing development,
• Review existing Council policies as they relate to development of land in flood liable areas,
• Consider measures for the management of flood affected land and
• Develop the Ariah Park and Springdale Floodplain Risk Management Plan which:

1. Proposes modifications to existing Council policies to ensure that the development of flood affected land is undertaken so as to be compatible with the flood hazard and risk.
2. Sets out the recommended program of works and measures aimed at reducing over time, the social, environmental and economic impacts of flooding.
3. Provides a program for implementation of the proposed works and measures.

Outcomes

A summary of the study and plan outcomes are:

• Indicative extent and depth of inundation for the 1% AEP (1-in-100 year event) and a range of floods between 20% AEP and probable maximum flood
• Recommending a graded set of controls over development according to flood risk including minimum habitable floor levels
• Recommending a flood warning system for Springdale and a vegetation management plan
• Recommending investigating a concept design of a trunk drainage upgrade for Ariah Park

At their meeting held on Tuesday 11 October 2023, the Ariah Park and Springdale Floodplain Risk Management Committee recommended that the draft study and plan be placed on public exhibition.
