All surface run-o me Sd area drains to the driveway artd heads -n>mpeded ou, of the narrow driveway chute directly a»°ss |he road lake This is roughly the same line that a skidding automobile I^uldlonow on a frLh driveway surface once downward travel on the steep grade began with no oail-out position. Proposal The solution we propose is a driveway that enters at the eastern edge of the site addressing the concern for sitelines on Bayside Road but then turns generally to the West and traverses he bank with a gradual 8% straight-line driveway that ^ natural contour as it approaches the West line. A relief P°st'on ( nearly flat) occurs at this point allowing the driver to turn North ind agL ascend even more gradually ( 6% grade ) ^ ° the building pad. This second leg follows very near^ the natural contour requiring minimal revision of the existing surface. The benefits of this solution are found in every area of concern. This plan calls for the least soil removal and site *^® available courses of action. Cuts in the bank average 10 in depth as the driveway crosses the lot requiring the removal of aoDroximately 900 CY. Retaining walls would be installed on the uphill side of the drive as it traverses the bank. Only the number of trees would be lost and the existing vegetation would only be disturbed in the area of the cut and to allow for construction of the retaining walls. The downhill side of the bank would be protected and left undisturbed as much as possible. The surface water run-off would be allowed to drain rnuch as it does now. Water traveling down the West leg of the driveway would able to leave the drive and travel down the bank approximately 50‘ before reaching the road. Only water moving down the traversing slope would exit directly onto the road.
