What is the reason for the curbing on 1/4 of the left side of the driveway? I would think you would want a uniform look even if it is just for water run off so mud doesnt wash onto the driveway. Second question: With a permeable application, what happens if mud,dirt,soil, and crap fill the cracks of the driveway. To me, each time the lawn crew is there, they are going to have a terrible time blowing off the driveway and getting grass out of the cracks without blowing the small rocks in the cracks out of the cracks. Third: Your work is amazing, and i cannot possible fathom the idea of landing a job this large scale, but your work is always top notch and i love the videos.
