Floodplain Risk Management Study and Plan

Blackmans Swamp Creek and Ploughmans Creek Flood Risk Management Study and Plan

Study Objectives

Orange City Council (Council) commissioned the preparation of the Blackmans Swamp Creek and Ploughmans Creek Flood Study (Flood Study) and the Blackmans Swamp Creek and Ploughmans Creek Floodplain Risk Management Study and Plan (FRMS&P).

The objective of the Flood Study was to define the nature of both main stream flooding and major overland flow at Orange for flood frequencies ranging between 20 and 0.2 per cent Annual Exceedance Probability (AEP), as well as for the Probable Maximum Flood (PMF). The Flood Study is the source of present day flooding conditions and was used as the basis for preparing the FRMS&P.

The objectives of the FRMS&P were to assess the impacts of flooding in Orange, review the measures that were recommended in 2009 FRMS&P along with Council’s current policies as they relate to development of land in flood liable areas, consider measures for the management of flood affected land and to develop a contemporary Floodplain Risk Management Plan for Orange 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.
