Some communities are surrounded by water, and the only option is to fill up the area to enable people to build. As long as there is development and people are living in this area, it is not a stress for investors to come in.
At this point this is where I will have to speak, land related activities are not usually to be conducted without survey, hence I don't think there will be any problems if the land is in a water area as long as LandDao has it's surveyors done there work on how the water could react to a level, I don't even encourage the project to be taking to a level where the RWA asset will be acquired in a waterlog area because if found out it's definitely going to affect the investors and eventually lead to sell off the property in loss and hence no investor will like to be in lost not even me.
