These lengths can be extended to match site conditions. Minimum shoulder spaci g is 6 inches. See illustration below for example of shoulder length. Basal Area: The basal area is comprised of the total area where t e C-33 San edia is- in contact with the receiving soil. The minimum required ba at area is lated by dividing the design flow rate by the soil loading rate spec fied in 2 272A (local codes may have differing loading rates). .. : ,4�p to DWDY E.WAITE Combining Hydraulic Layout and Basal Area Requirement LICENSED DESIGNER "'." Dula To combine the coil layout and the basal area, start th the coil layout. Refer to Tables 4 or 5 for minimum shoulder lengths. Zero to 5 percent slopes (0.5% slope) are considered flat for basal area calculations a d set back considerations. It may be advisable to place the coils on the p side of the basal area when the slope is 2 % or more. On flat sites, the coils s ould be placed in the center of the basal area. The coils will be arranged in a sing, line, although the Line can be curved to match site contours. Also, no emitter s all be placed within 6 inches of the C-33 sand media shoulder. On sloping sites (>5 to 20% slope) the coils will be pla parallel to the contour and one edge of the coils must be placed about 12 i ches from the upslope basal boundary. There must be at least 6 inches sep ration added between the drip tubing in different OS-50 coils. With the 05-100 cot the spacing is already included with the 85 inch (7.1 foot) area. Side slope of the C-33 sand media is at least a 1 u 1 slope. Add the minimum coil long to e„si pes determine the minimum basa, area length.

The intent is not to have too much additional cover over the final C-33 sand layer. Placing too much cover will inhibit,plant root growth. Because the C-33 sand is sub-surface irrigated, grass and other ground cover will grow rapidly, forming a firm protective cover over the OSCAR. At the end of the first growing season the C-33 sand layer will be as firm as native soil to walk on. Options include: • landscaping jute mat with grass seed or ground cover plan 1ngs • a thin layer of mineral soil low in organic content (<10% orianics) • Thin layer of crushed or washed rock for wind erosion Prot ction. • Thin layer of bark to wood chips.
