There are two concerns where the new paving meets with each parking area: drainage and protecting the edge of the pavement. The alley's grade varies greatly from driveway to driveway. The contractor will use existing driveway material, supplemented where necessary, to grade the driveway to "meet" the paving about one foot in. That means digging down in some driveways and building up to the pavement in others. It does not mean that the new pavement will provide each driveway with a one-foot "lip" of asphalt.
