Scope of Work The proposed paving area is 39,227 S.F. The total limits of disturbed area is 53,461 S.F. which includes the proposed paving and 14,234 S.F. peripheral disturbance for Ditch Regrading and Slope/Shoulder Tie-In to ensure positive drainage around the parking lot. Resurfacing will take place on top of the existing Gravel Lot. The existing Gravel Lot will be fine graded and then a 2” layer of Base Stone (21-A) will be applied to supplement existing gravel base and provide a leveling course prior to applying pavement. Estimated Stone including edge and shoulder treatment, is about 325 Cubic Yards or 657 Tons. Sequence of Construction: A. Install Erosion & Sediment perimeter controls. B. Install traffic control, remove existing culvert pipe and install new culvert at entrance. C. Immediately stabilize ditch line at entrance once new pipe installed. D. Re-pull/grade existing swale along the southwestern side of the parking lot to ensure positive drainage and immediately stabilize with blankets and matting. E. Fine grade existing parking lot area and apply 2” leveling course of 21-A, proof rolled/compacted. F. Begin paving operations. G. Install traffic control at entrance for tie-in to existing road (WP-2). H. Fine grade shoulder area around the perimeter of parking lot. I. Apply permanent seeding and mulch to all disturbed areas around the perimeter of parking lot not otherwise stabilized with pavement or gravel. J. Remove E&S controls once seeded areas are established.
