That are lots of variables that determine the quality of drainage around your home.  Often IMPROPER SLOPE (i.e. rise/run) is a commonly overlooked issue when installing a new landscape.  Proper drainage systems are a difficult for the home owner and contractor to come to terms on.  It’s a expense that can be quite costly and is usually all buried underground and gives no asetic benifit to the home.  Designscape’s favorite solution is to use the skill of grading to revert water to more ideal locations.  A great way is through a dry creek bed.  Installation methods vary but the best method is the look at one built by mother nature and try to recreate it.
