Young Shire Council commissioned the Floodplain Risk Management Study and Plan for the town of Young. 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 bordering Burrangong Creek and its tributaries, consider options for management of flood affected land and to develop a draft Floodplain Risk Management Plan (FRMP) which:

• 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.

• Proposes Flood Planning Levels for the various land uses in the Floodplain.

• Sets out the recommended program of works and measures aimed at reducing over time, the social, environmental and economic impacts of flooding.

• Provides a program for implementation of the proposed works and measures.

The FRMS focusses on main stream flooding from Burrangong Creek and its tributary streams, as well as flooding on three principal overland flow paths in the urban sub-catchments on the northern slopes of town, which discharge to the creek through the Central Business District (CBD) area. Flooding problems on these overland flow paths arise from surcharges of the local trunk stormwater system which comprises a mix of pipes, culverts and open drains.

The solutions of problems resulting from surcharges of the minor stormwater system in individual allotments, remote from the creeks and the above overland flow paths, which may occur during localised storms, are outside the scope of the present investigation.
