The challenge for any promoters of projects for the fast track will be that they recognise that dealing effectively with natural resources and planning effectively means doing a thorough effects assessment and knowing what natural resources we are dealing with in order to assess effects and then plan and design the project to avoid those. There was one project in Christchurch on the Ōpāwaho Heathcote River some years ago. There's a big loop on that river through Woolston that meant that floodwaters go more slowly to the sea, so the engineers thought they would do the Woolston Cut so that floodwaters would go more quickly. They didn't assess the fact that the saltwater wedge would go further up the river. That led to a much greater tidal influence, it led to the banks crumbling, and it led to trees dying because of that saltwater influence. So the engineers, by failing to take into account basic ecology, then had to build the Woolston barrage to prevent the water going that quickly to the sea.
