low (5 sites) is based on the low acreage need (98) divided by the high site size (98 divided by 20). The high sites (23) is <br />based on the high acreage need (229) divided by the low site size (229 divided by 20). <br />The average sites needed is the arithmetic mean of the low and high, rounded to the nearest whole number. For example, <br />for sites 10 to 20 acres, the average between 5 and 23 sites is 14 sites. <br />Table 33 shows Eugene's industrial land and site needs for employment <br />on sites larger than 10 acres. It shows that Eugene will need a total of 820 <br />suitable gross acres of industrial land on sites larger than 10 acres over the <br />20-year planning period. Table 33 shows: <br />Needed Sites, based on the average shown in Table 32 (e.g.,14 sites <br />between 10 and 20 acres). <br />Average site size, generally based on the average between the low <br />and high site size in Table 33. For example, the average site size for <br />sites between 10 to 20 acres is 15 acres. <br />• Suitable Gross Acres needed, the number of needed sites <br />multiplied by the average site size. <br />Table 33.
