Thank you, Mr Mayor. Recently in this chamber, we know we had a notice of motion from Councillor Zamprogno, which was asking us to take a firm stance in support of the raising of the Warragamba Dam wall. At the time, the majority said no , they did not want to take that stance, and generally that was based on the requirement of getting more information about what is going on with this process. Since that time, and actually since I wrote this notice of motion, there has been a lot of frantic activity. There's been a lot of media coverage. There's been a lot of questions asked in State Parliament. There's been an update at the Flood Committee. There's been a change, I believe, in Labor Party policy.
So all of that's happened. So I'm just saying at the start, I'm open to strengthening this notice of motion if anyone wants to contribute to it, because since I wrote it, a few things have changed. We saw a bill enter the Parliament. It had a parliamentary inquiry in the Legislative Council. It then passed both houses, and all of that was done within one month, which is quite an extraordinary time frame for the passing of a bill. So what was the big rush on this bill, was the question people have been asking, and quite an unusual state of affairs when it comes to legislation to do so so rapidly. And the reason given was that it was required to change the National Parks Act to enable inundation upstream behind the dam wall.
It was needed for that legislation to be changed to enable the EIS, the Environmental Impact Study, to be completed. An odd suggestion, I would have thought. And during the parliamentary inquiry, this question was put to the Chief Executive of Infrastructure New South Wales, Jim Betts, who said, No, that is not necessary. We do not need that legislation changed to proceed with the EIS. So there was no real need. There has been no real need to push that forward. And as we put in a submission to the inquiry , that we were concerned with the limited amount of time that was given to stakeholders, of which we are one of the major stakeholders here, that we didn't feel there was enough time to contribute our position on that particular bill and the inquiry that was attached to it, and that we're still waiting on the release of the regional flood study, which is being prepared by Infrastructure New South Wales, and also that to date we have not been given any of the findings of the environmental impact study, which has been done to date.
All things that, as major stakeholders, it is quite important that we should be being told about. We know from the recent briefing that we had from Infrastructure New South Wales at the last floodplain meeting, we know that the mapping is underway for the flood study, that possibly this is going to be released by the end of the year. We saw some of the graphs, we saw the extent of the flooding. It's quite detailed. However, it does not include consideration of localised flooding or cumulative overland flooding, and so that's a gap. It also does not, of course, encompass the inundation from the other catchment areas such as the Macdonald Valley or from the Colo River, and even as we heard when we went out to St Albans, the possible inundation from the Hunter region from the rivers down there.
So why is the government withholding this information and not giving it to us? This is a huge issue for us in this area because if the business case is solid and if the environmental damage is minimal and if the real driving force behind this project is not development, then why can't we see it? Why can't we see what these studies are bringing forward? We've seen a huge degree of change in land use in the floodplain, which is not necessarily being considered. There appears to be an assumption that the modelling for the flooding is going to be that we presume that floods will occur as they've always occurred. And this isn't necessarily true because now we know that there are changes due to unprecedented climatic changes and that floods are not the same.
Our climate is in a state of severe disruption. The evidence is there that the climate is so disrupted that we simply cannot rely on past events. And we've seen this in the floods that they had in Forbes, and we've seen them in the floods in Japan. It's not characteristic. You cannot just think that a flood is going to come the same as it's always come. The intensification of the water cycle and the changed land use, so the amount of vegetation and soil that has been removed, the grading of the land and the construction of drainage networks all feeding into the streams that feed into the rivers all will change the flood behaviour. Now. From what I gathered from our update the other day, this is not being considered.
Those specific changes are not being considered. The flood modelling is being done on different scenarios, but I believe it's being done on past flood information. So we need transparency in this regard. And when you get to point three, we need to see what data has been used when the other options as alternatives to the raising of the dam wall have been carried out. Minister Ayres has said that all infrastructure and non-infrastructure options have been looked at, but where are the data and where are the conclusions? Because in the strategy itself, there's footnotes that say that this has occurred, but the documents that form the footnotes are not available to the public, and I believe they're not available to parliamentarians as well.
So the level of concern within the community is growing. At the start, people were wanting to know, to see what the business case would be, to see what the environmental impact statement would bring up, and then suddenly the government has thrown in this projectile of a bill passing rapidly through, which will actually allow upstream inundation of a World Heritage location, which is of huge concern. So that leads people to making an inference that this is all about development. So this is the big question. Many believe that it is. There's mixed messages coming out through the media. We saw when the corridor meetings were on, we had Infrastructure New South Wales telling us one thing and Department of Planning telling people in the room another thing.
Why would the government be proposing to put more people in a floodplain? It just goes beyond belief. And so there were various, I just looked up some various statistics and so on about how much. There were questions asked in Parliament recently about how many hectares of land in different local government areas are actually flood prone. So in the Hawkesbury, there are 23,900 hectares of flood prone land, 11 and a half thousand hectares in Penrith LGA, and 4,700 hectares in Blacktown. And so how many hectares of land. .. which are currently flood prone, will have development potential if the Warragamba Dam is raised by 14 metres. That appears to be the question, but I'm pretty sure this question wasn't answered.
And so we have to wait until the Department of Planning has done a study, which is called a regional land use planning framework, which is part of the floodplain strategy, which is fine. That would be good if that was done, but my concern is relating to the absence of information feeding into the order of how the information is coming out. It does seem that the government has yet again made a decision and gone back to be filling in the gaps and finding the things to justify their decision as it's going on. Another question that I thought was interesting and which I think that we should be getting explanations for is regarding the amount of properties in the North West Priority Growth Area which are flood prone.
So 21,000 dwellings in the North West Growth Sector are on flood prone land. Now that's a lot of houses. And then we have had from the government, and it came out in the inquiry, that they're anticipating putting another 134,000 people in the floodplain. So I just find a lot of this. I was pleased to read, though, that MP Kevin Conolly did say in a speech the other day that only lower density development zones are being located on flood prone land, with zones for medium or higher density development being placed above the PMF. That was encouraging, given that there's proposed new developments in Marsden Park North and Dean Park, which could be flood affected as well. So I've brought this forward.
I think that we deserve to have these questions answered. I think that if we are a major stakeholder, and this is a major public expenditure of public funds, that we should be seeking this information. And I think that we're owed that information about the future for planning. I know we've asked about it, for example, for the Oakville area. We've asked what the future is there. We need to know what they are intending to do. We deserve to know, and they should not be making major decisions like this without actually telling us what exactly the future plans are. If the future plans are to put development there, well, say that to the people and let the people decide if that's the risk they want to take in the floodplain, because that's what that's all about.
But you can't hide it and infer it's for one thing and then have a hidden agenda about that. And just to finish off, also the other thing was often in the media and the parliamentary speeches, there's references to the Brisbane floods and what happened in Brisbane. And when we're at the floodplain management conference, it was quite clear that there were issues with the dual use of a dam in Brisbane being for water storage and also for flood mitigation, which is exactly what this is proposed to be. And I don't think using that as a referral is a very good way to sell the proposal to people anyway. So last weekend, amid a flurry of various media articles that have come out, was an article by Elizabeth Farrelly in the Sydney Morning Herald, which I expect Councillor Connolly will call a left-wing paper, but before he does, I'd just like to point out that the Sunday Telegraph's front headline last week was Get kids off Nauru.
So things are changing. So I want to read just this quote from Elizabeth Farrelly. Which she said, floodplains are fertile, so they make good farms but bad suburbs. Destroying farmland for sprawl was dumb to start with. Destroying wilderness to protect and propagate that sprawl verges on mindlessness. So our call to the government is to give us the information so we as stakeholders can properly engage in the decision that they're making and that we know the truth about what the intentions are for this particular project.
