The Blue Mountains World Heritage Area is currently under threat from a NSW government proposal to raise Warragamba Dam.
If Warragamba Dam wall is raised by 14 metres, the dam will hold the equivalent of two additional Sydney Harbours. 4,700 hectares of World Heritage listed National Parks an 1,800 hectares of declared Wilderness Areas will be forever scarred from sedimentation, erosion and invasion of exotic plants.
The push of urban sprawl
The NSW Government has said the raising of Warragamba Dam will allow them to open 2,355 hectares of western Sydney floodplains to urban sprawl by creating flood mitigation capacity in the existing dam. This equates to an addition 94,000 houses squashed into western Sydney. This is a seriously dangerous idea.
The move area on the above map shows land earmarked for urban sprawl, and the blue area Hawkesbury-Nepean floodplains. Property developers think that raising Warragamba Dam will allow them to claim thousands of new houses they build on floodplains (overlap of pink and blue) will be safe from flooding. This will put thousands of human lives at risk, with a raised dam only having marginal impacts on reducing downstream floods.
