Boorowa Floodplain Risk Management Study and Plan - Community Consultation

Hilltops Council (Council) commissioned the Floodplain Risk Management Study and Plan for the township of Boorowa. 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:\r\ni) 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.\r\nii) Proposes Flood Planning Levels for the various land uses in the floodplain.\r\niii) Sets out the recommended program of works and measures aimed at reducing over time, the social, environmental and economic impacts of flooding.\r\niv) Provides a program for implementation of the proposed works and measures.\r\n\r\nThe FRMS focuses on Main Stream Flooding from the Boorowa River, Ryans Creek and Ryans Tributary, as well as two major un-named tributaries, Minor Tributary Flooding caused by high flows in the minor un-named tributaries which drain to the aforementioned watercourses, and Major Overland Flow areas which occur in the urbanised parts of Boorowa and its immediate surrounds.希托普斯郡议会（Hilltops Council，以下简称“议会”）委托开展布尔瓦（Boorowa）镇区的洪水平原风险管理研究与规划项目。本次洪水平原风险管理研究（Floodplain Risk Management Study, FRMS）的总体目标为：评估洪水灾害影响，审查议会现行涉及洪水易发区域土地开发的相关政策，研讨受洪水影响土地的管理方案，并制定洪水平原风险管理规划（Floodplain Risk Management Plan, FRMP），该规划需达成以下目标： 一、提出对议会现行政策的修订方案，确保受洪水影响土地的开发活动与洪水灾害及风险相适配； 二、针对洪水平原内各类土地用途拟定洪水规划水位； 三、列明旨在长期降低洪水带来的社会、环境与经济影响的推荐工程计划与应对措施； 四、拟定拟议工程与措施的实施计划。 本次FRMS的研究范围涵盖布尔瓦河（Boorowa River）、莱恩溪（Ryans Creek）及莱恩支流（Ryans Tributary）的干流洪水，以及两条主要无名支流；同时包括汇入上述水系的小型无名支流因高流量引发的小型支流洪水，以及布尔瓦镇区及其周边城市化区域内出现的主要陆上径流区域。
