Structure Plan - Rural City of Murray Bridge

STRATEGIC CONTEXT 044.3.11 Stormwater Management StrategyWallbridge and Gilbert have recently prepared a draftStormwater Management Strategy for the Rural Cityof Murray Bridge. This is related to the existing townboundary and not the study area relevant to this study.The objective of this study was to determine the beststormwater management strategy accounting for:• Use and rationalisation of existing infrastructure;• Supply and demand analysis;• Current stormwater management plan;• Water independence strategy for Murray Bridge;• Known development activity;• Current capital works program; and• Available government funding.The strategy identifi ed the existing stormwater detentionbasins and pumping mains. It also identifi ed the potentialyields of the existing catchments.Possible options for consideration included the provisionof new pump-mains, existing basins which will requireadditional capacity and new basins. Also considered wasthe possible future supply of recycled water in conjunctionwith the District Council of Mount Barker.Supporting this strategy is the recent announcement ofa $7.115m grant approval to Council under the NationalUrban Water and Desalination Plan – StormwaterHarvesting and Reuse Projects.4.4 Implications forStructure PlanKey issues arising from these strategic investigationsinclude:• The State Strategic Plan establishes population and jobgrowth targets for both Greater Adelaide and RegionalSouth Australia;• The study area includes land which is located outsideof the existing township boundary/growth areasdesignated by the 30 Year Plan for Greater Adelaideand as such amendments to the Planning Strategywould be required to facilitate future urban developmentwithin those areas;• The Murray Mallee Region Plan indicates that MurrayBridge will accommodate the signifi cant majority ofgrowth for the region;• The Rural City of Murray Bridge has a clear strategicpolicy platform supporting sustainable growth;• The use of treated wastewater and stormwater reuseis a major opportunity to promote sustainable urbandevelopment;• Whilst an open space hierarchy has beenrecommended to Council (Suter Planning), revisionsto that hierarchy/strategy will be required pending thefuture growth areas arising from this Structure Planprocess. It is possible that additional neighbourhoodlevel open space may be required for some growthareas and other areas rationalised/consolidated,depending on their scale and spatial relationship andconnections to existing open space;• The 30 Year Plan for Greater Adelaide anticipatesa new urban form which includes higher dwellingdensities in appropriate locations;• The ageing of the population and other social changeswill lead to a signifi cant increase in lone personhouseholds thereby changing demands in respect todwelling form; and• Maintaining town character is an important strategicobjective.• Revitalisation and maintaining primacy of the RegionalTown Centre;• Reinforcing a distinct road transport hierarchy whichbalances infrastructure maintenance, urban characterand amenity, and accessibility.19
