Managemnt zones were defined based on hydraulic, ecological, cultural and socio-economic criteria. The seven zones include:MZ AD - Major Discharge Areas, Defined FloodwaysMZ AID - Major Discharge AreasIll Defined Floodways MZ BL - Flood Storage and Secondary Flood Discharge Areas, MZ BU - Flood Storage and Secondary Flood Discharge AreasMZ C - Flood Fringe and Flood Protected Developed AreasMZ CU - Urban areas managed by Local CouncilMZ D - Special Environmental and Cultural Protection ZoneFollowing the Floodplain Management Plan, the management zones indicate what rules apply for the granting or ammendment of flood work approvals.The risk to life and property from the effects of flooding is addressed in the design of the management zones and the rules for granting or amending flood work approvals by:identifying hydraulic thresholds within management zones where the local and cumulative impact of flood work development should be limited to prevent flood flow redistribution, increased flood velocities and flood levels, anddeveloping rules to limit the granting of flood work approvals for flood works that are minor in nature, including flood protection works to protect infrastructure and livestock, in zones where major flood discharge occurs (Upper Namoi Management Zones AD, AID and D), anddeveloping rules to allow landholders to apply for certain flood protection works in Upper Namoi Management Zones BU and BL (where temporary storage of large floods occurs) without requiring advertising, to protect infrastructure, crops and livestock from flood events, andspecifying the nature of flood works that can be constructed. |
