Braidwood Floodplain Risk Management Study and Plan

Study Objectives

Queanbeyan-Palerang Regional Council commissioned the Floodplain Risk Management Study and Plan (FRMS&P)for the township of Braidwood. The overall objectives of the Floodplain Risk Management Study (FRMS) were to assess the impacts of flooding, review existing Council policies as they relate to development of land in flood liable areas, consider options for the management of flood affected land and to develop a Floodplain Risk Management Plan (FRMP) 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. Proposes Flood Planning Levels for the various land uses in the floodplain.
  3. Sets out the recommended program of works and measures aimed at reducing over time, the social, environmental and economic impacts of flooding.
  4. Provides a program for implementation of the proposed works and measures.

The FRMS focuses on Main Stream Flooding along Gillamatong Creek, Monkittee Creek, Mona Creek, Flood Creek and Recreation Ground Creek, Minor Tributary Flooding that occurs along an unnamed tributary which joins Monkittee Creek downstream of the Wallace Street bridge (denoted herein as “Unnamed Tributary”), and Major Overland Flow in parts of the Recreation Ground Creek catchment.

Study Activities

The activities undertaken in this FRMS&P included:

  1. Undertaking a consultation program over the course of the study to ensure that the Braidwood community was informed of the objectives, progress and outcomes over the course of the study.
  2. Review and updating of flooding patterns in Braidwood for flood events up to the Probable Maximum Flood (PMF).
  3. Assessment of the economic impacts of flooding, including the numbers of affected properties and estimation of flood damages.
  4. Review of current flood related planning controls for Braidwood and their compatibility with flooding conditions.
  5. Strategic review of potential floodplain risk management works and measures aimed at reducing flood damages, including an economic assessment of the most promising measures.
  6. Ranking of works and measures using a multi-objective scoring system which took into account economic, financial, environmental and planning considerations.
  7. Preparation of a FRMP for the town.
