Natural grading (with the dirt, natural rock and gravel material only) of your property when done properly is the best way to divert water away from your home and walls then out toward the street.

This is done by pitch of grade only and water being diverted properly. This is why builders leave backyards that are sloped away from walls and your home creating a V like area in the center (seen above) of your yard that leads out toward the front on most homes.

When you are installing a pool and landscaping drainage pipes are to be used only when the path of the water is blocked by an obstruction. —  Tim H., Pool Contractor

When you are installing a pool and landscaping drainage pipes are to be used only when the path of the water is blocked by an obstruction (pavers, concrete, synthetic turf etc…). If obstructed the water needs to be diverted through a drainage pipe or deck drain (on pools) and directed passed the obstruction only leading back to the V depression in the dirt.

When decorative rock is installed you should not flatten out your landscape. Install the decorative rock on top of the grading left by builder and leave the grading pitched away from your home, walls and leading to the front with the V shape depression. The water will build up in this V shaped depression and slowly flow through the decorative rock out to the front.

When there is excessive rain there will be some build up in the areas where the water is accumulating in the V shape depression and these areas will become soft so if you walk on them you may sink in. This is normal so don’t walk in these areas until they dry out a bit. The majority of the time most of the water will drain into the ground returning to the water table which is the goal. During an intense downpour it will flow in this V depression out through the decorative rock and through a drainage brick (brick with gaps for water) left by builder in the center of your wall or can simply drain through a gate entry.

While it takes no special training or certification to do basic yard tasks, some states require professional licensing in order to practice landscape design or landscape architecture professionally. Although years of experience working under a licensed landscaping professional might be enough to become a licensed landscape architect or designer, it usually requires a formal college degree in one of the two disciplines.
