Patio With Gravel Drainage Area

Below is a Patio we built. (the pergola was built by the homeowner) Every project is interesting, and this one is no exception. We installed 12" of Clean gravel under the pavers and ran pipes from the downspout into the area. Now instead of flooding the small back yard, the rain water will be dispersed into the gravel 'holding' area under the patio. We give the homeowner and his friend the credit for the idea.
