built space but, equally clearly, not all employment can be <br />accommodated this way. <br />The city lost more than 15,000 jobs during the recession, between <br />2006 and 2010. It is likely that some of the future job growth in <br />Eugene could be accommodated in the existing built space that <br />was vacated. <br />Table 24 shows the amount of jobs lost during 2006-2010 that <br />could be accommodated through existing built space: <br />o Commercial and retail. We project that the vacant spaces <br />resulting from commercial and retail jobs lost during the <br />2006 to 2010 period will be refilled with new employment <br />growth. <br />o Industrial. Refill of built industrial space is not as efficient <br />as refill of commercial space since industrial sites are often <br />custom-built for special purposes. Due to re-purposing <br />inefficiencies, we project that industrial built space will <br />refill on sites smaller than 10 acres to only a portion of pre- <br />recession capacity. Table 24 assumes that 3,454 new <br />employees will locate in existing industrial built spaces, <br />which is 55% of the industrial jobs that were lost during <br />the 2006-2010 period. <br />Table 24.

The City of <br />Eugene used the Employees per acre (EPA) measurement. EPA is the total <br />number of employees divided by the size of the site. <br />Part 11 - Eugene Economic Opportunities Analysis ECONorthwest Page 107 <br />
