Site Design. Grading, setbacks, and facility siting shall be designed to meet the operational programs of the park as defined in the city of Malibu parks master plan. Notwithstanding any other provision of this chapter, grading in all new parks shall be limited to not more than 1,000 cubic yards per acre, except that grading required for sports fields designed to accommodate commonly accepted facility dimensions shall be exempt from these limitations. This shall not include removal of natural scenic amenities, including large stands of trees, rock outcroppings, ravines and swales and removal of site defining topographic features. This standard recognizes that recreational trails are an integral part of parks and that park facilities may be visible from recreational trails. The facility shall be designed to minimize noise and disruption to nearby residents.
