What is the policy regarding drainage?
Your lot has been graded per county/city requirements for proper drainage. It is the homeowner’s responsibility to plant grass or take other measures in un-sodded areas to prevent erosion and improper drainage from frequent rains. The homeowner is also responsible for replacing and maintaining any plants or grass in these areas. After periods of normal rain, you can expect water to drain off within 24 hours in most areas and 48 hours in swales. After a period of heavy rains, it may take considerably longer.
