All residential lots receive a grading certificate showing positive drainage that is signed and stamped by a professional land surveyor or a professional registered engineer. Your builder should provide you with a copy of this document. Commonly, drainage problems occur as the result of changes in the grading when resident's create or change landscaping. Please take into consideration the drainage patterns in your yard when you are landscaping. If changes you make to the drainage of your yard adversely affect another's yard, you are liable. If this is not the case, it is an issue that you need to address with your home builder.
