REAL ESTATE LAWS BUILDER LIABILITY IN NORTH CAROLINA?

I have the couple of questions yet the many critical subject is What can I do?

Situation

My father as well as I paid for the residence code brand new in 2004 from the builder Pine Grove Corporation

There was the drainage tide about 4 feet far-reaching as well as may be dual feet low when you purchased the home in the distant behind dilemma of the property. Since my family home has the rivulet which floods you asked if this rivulet would inundate (The answer to which was no it will not inundate the tide it is only the run off for rain} Well it floods as well as floods bad the single nearby resident only mislaid their residence over their small run off as well as I had to be taken from my residence in the rescue vessel even yet the H2O never done it in to the residence itself only up to the porch) On the consult from the builder it states which there in no creeks, streams, lakes, river, or using H2O nearby the property,

Question How can they state this when it goes by everyone’s property?

Next Situation
The family which mislaid their residence the word association is still starting by their box yet they found out the builder did not have the permits to set up the houses where he did, his association built twenty residence in wetland?

Question
What if anything can the home owners do? Can you sue the builder? And what have been the contingency of us winning?

I consider he should during slightest buy the houses behind with the land given it came in the package understanding when he sole it. I don’t even caring about the thousands I have put in to this residence I only wish the builder to repay the homeowners upon what you paid him.
