Hi, I am looking to buy a property to live in, in the Blacktown council area in western Sydney. Was researching flooding are etc using their online map. Came across bold dash line marked area in many places on the map. An example is shown in the image below and it's marked as "Development Control Plan Items": I did search on the council's website and their development plans, I could not find any detail. I have seen this marking in along a busy road and also on a quiet road as the one in the picture. What would be possible cases for this marking? Road extension? What to expect if I buy a property around it?
