With all the rain that the valley experienced last week, it is appropriate that we touch on landscape drainage. Because the ground conditions in the Phoenix area are typically dry, when heavy rains hit it causes fast flowing water that will erode landscape and wash away granite and dirt. When planning your landscape make sure your designer understands that proper drainage is key to maintaining your landscape during these storms. The use of river rock and drains can help control the flow of water throughout your property and keep your landscape from washing away. This landscape in the north Phoenix area has some extreme conditions and shows the need for planning for drainage. If this yard did not have drains, river rock and boulders to control the water, it would have been a disaster when the rains hit last week.
