Properties around water logged areas can be developed actually they are usually one the very good areas that capture people's interests especially when they have started being developed.
I don't think a property in a water logged area could be suitable for the LandDAO team, not just for them but for the buyers that would be interested to be a land parcel. A water logged area may requires huge amounts of sand to refill the area before it will be suitable for any building construction.
If you want to sell a land or you have a land you want the team contributors to review, it must be a good and cheap land that will be suitable for whether building or recreational purposes.
