GawlerRiver FloodMitigationScheme
What will theMark TwoScheme Include?
(Note these stepsmayoccur concurrentlyandnot necessarily in the following order)
One Reconfirmwith theConstituent Councils that a 1 in 100 year level of protection is theprotection standard that is tobe pursued in the development of the
Gawler River FloodMitigationScheme -Mark TwoStrategy.
Two Determine if a second dam on theNorthParaRiver is an option. TheGRFMABoard has recentlyaccepted a tender for aFindingsReport to undertakean
assessment todetermine if a second dam is required and feasible.
Three TheGawler River FloodplainMappingModel should bemaintained as the reference tool to demonstrate the level of flood protection and validityof design
of land proposed for development as part of the approval process. To achieve this, themodel shouldbe upgraded to include recent works such as the
NorthernExpresswayworks and theadditional floodplainmapping completedas part of the Light River TemplersCreek Salt CreekMappingStudy by the
District Council of Mallala.
Four To further develop the preliminaryassessment of possible local area levees prepared in the 2008Gawler River FloodplainMappingStudy at Gawler, Angle
ValeandTwoWells and develop a levee strategy for Virginia to a robust design standardwitha staging plan. Undertakea cost benefit study for each stage
of theplan.
Five Establish a protocol with theFloodplainCouncils that wheredevelopment of land in areas
identified as ‘at risk of flooding’ is planned to proceed by the
implementation of a local area levee that mapping of theproposed levees on theGawler River FloodplainMappingStudyModel will be required.
Maintain aworking relationshipwith theAustralianRail TrackCorporation to ensure that any changes toRailtrack infrastructureof culverts and rail heights
aremapped on theGawler River FloodplainMappingStudyModel to identify any changes to flooding impacts.
Seven Developa funding strategy for flood protection that is deliveredby local area levees on thequestions of who shouldown andmaintain the levees and
whether local area levees are regional works that theGRFMA should fund or are they local works that are the responsibility of the local Council.
Eight Investigate opportunities for funding partners and grants toundertake the necessaryassessments and designs.
Nine TheSchemewill also seek to clarify, through the Local Government Association, thepolicyand legal framework aroundmaintenance of rivers and creeks
where those rivers and creeks are part of the regional floodmanagement plan. Under current legislation a landowner is responsible for the condition of a
creek or waterway on private land.
