Stock Pile Plan For North Airfield Laydown Area

LAX Stock PileThe “North Airfield Stockpile Grading Plan” at LAX provided a grading and erosion control plan for the placement of excess material from the Interim West Busing Terminal Project by Hatch MacDonald and their subcontractors.  The plans showed a contour graded stockpile mound in the contractor’s laydown area, including 4:1 side slopes, 10% and 5% ramps, and earthen swales for perimeter drainage.  The grading plans were prepared at 40 scale over a topographic survey of the area.  Erosion control plans were prepared showing the necessary facilities and devices needed to prevent erosion from the stockpile.
